Definitions
- the present invention relates to a process for producing a multicoat paint system in which a basecoat film or several directly successive basecoat films are produced directly on a metallic substrate coated with a cured electrocoating, a clearcoat film is produced directly on one or the uppermost of the multiple basecoat films, and then the one or more basecoat films and the clearcoat film are cured together.
- the present invention relates to a multi-layer coating, which was prepared by the process according to the invention.
- Multicoat paint systems on metallic substrates for example multicoat paint systems in the automotive industry, are known.
- such multicoat paint systems comprise, viewed from the metallic substrate, an electrodeposition coating layer, a layer applied directly to the electrodeposition coating layer, usually referred to as surfacer layer, at least one layer containing color and / or effect pigments and generally referred to as basecoat layer and a clearcoat layer.
- the electrophoretically applied electrodeposition coating layer basically serves to protect the substrate from corrosion.
- the surfacer layer serves primarily to protect against mechanical stress, such as, for example, falling rocks, and also to fill in unevennesses in the substrate.
- the next layer, referred to as the basecoat layer is primarily responsible for creating aesthetic properties such as color and / or effects such as the flop, while the subsequent ones Clearcoat especially the scratch resistance and the gloss of the multi-layer coating is used.
- the production of these multicoat paint systems is generally carried out by initially applying or depositing an electrodeposition paint, in particular a cathodic electrodeposition paint, electrophoretically on the metallic substrate, for example an automobile body.
- the metallic substrate can be pretreated differently prior to the deposition of the electrodeposition coating, for example, known conversion coatings such as phosphate coatings, in particular zinc phosphate coatings, can be applied.
- the deposition process of the electrocoating generally takes place in corresponding electrocoating pools.
- the coated substrate is removed from the basin, optionally rinsed and flashed and / or intermediately dried, and finally the applied electrodeposition paint is cured. In this case, layer thicknesses of about 15 to 25 micrometers are desired.
- the so-called filler is applied directly to the cured electrodeposition coating layer, optionally flashed off and / or intermediately dried and then cured.
- layer thicknesses of, for example, 25 to 45 micrometers are desired.
- a so-called basecoat containing color and / or effect pigments is then applied, optionally flashed off and / or intermediately dried, and a clearcoat applied directly to the basecoat film thus prepared without separate curing.
- the basecoat film and optionally also previously flashed and / or intermediately dried clearcoat film are cured together (wet-on-wet process).
- the cured basecoat film generally has comparatively small layer thicknesses of, for example, 10 to 20 micrometers, layer thicknesses of, for example, 30 to 60 micrometers are desired for the cured clearcoat film in order to achieve the application-technological properties described.
- the application of filler, basecoat and clearcoat can be carried out, for example, via the application methods of pneumatic and / or electrostatic spray application known to those skilled in the art. Filler and basecoat are now increasingly used for environmental reasons as aqueous coating materials.
- this coating layer which is not separately cured, is then often referred to as the basecoat film (and no longer as the filler film) or, in contrast to a second basecoat film applied thereto, is referred to as the first basecoat film.
- the coating layer produced directly on the electrodeposition coating layer is flashed off only at room temperature and / or intermediately dried at elevated temperatures, without curing, which is known to require regularly increased curing temperatures and / or long curing times.
- the basecoat (b. 2.1) or at least one of the basecoats (b.2.2.x) comprises at least one aqueous polyurethane-polyurea dispersion (PD) comprising polyurethane-polyurea particles, wherein the polyurethane-polyurea particles contained in the dispersion (PD) are anionic and / or or groups which can be converted into anionic groups and have an average particle size of 40 to 2000 nm and a gel fraction of at least 50%.
- PD aqueous polyurethane-polyurea dispersion
- the polyurethane-polyurea particles contained in the dispersion (PD) are anionic and / or or groups which can be converted into anionic groups and have an average particle size of 40 to 2000 nm and a gel fraction of at least 50%.
- the abovementioned method is also referred to below as the method according to the invention and is accordingly the subject of the present invention.
- Preferred embodiments of the method according to the invention are given in the description below and in the subclaims.
- the present invention is a multi-layer coating, which was prepared by the method according to the invention.
- the inventive method allows the production of multi-layer coatings waiving a separate curing step of the coating layer produced directly on the electrodeposition coating layer.
- this coating layer is referred to in the context of the present invention as a basecoat film.
- this basecoat film is cured together with optionally further basecoat films below the clearcoat film and the clearcoat film together.
- multi-layer coatings which have excellent stability against pinholes.
- the overall visual impression and the adhesion of these multicoat paint systems are also excellent and are at least at the level of multicoat paint systems which were produced by the standard process described above.
- the application of a coating agent to a substrate or the production of a coating layer on a substrate are as follows.
- the respective coating agent is applied such that the coating layer produced therefrom is arranged on the substrate, but does not necessarily have to be in direct contact with the substrate.
- other layers may be arranged between the coating layer and the substrate.
- the cured electrodeposition coating layer (E.1) is formed on the metallic substrate (S), but a conversion coating such as a zinc phosphating as described below may be disposed between the substrate and the electrodeposition coating layer.
- the same principle applies to the application of a coating agent (b) to a coating layer (A) produced by means of another coating agent (a) or to the production of a coating layer (B) on another coating layer (A).
- the coating layer (B) does not necessarily have to be in contact with the coating layer (A), it merely has to be arranged above it, that is to say on the side of the coating layer (A) facing away from the substrate.
- applying a coating agent directly to a substrate or producing a coating layer directly on a substrate is understood as follows.
- the respective coating agent is applied such that the coating layer produced therefrom is arranged on the substrate and is in direct contact with the substrate. In particular, no other layer is arranged between the coating layer and the substrate.
- Coating layers in direct contact so are arranged directly on top of each other.
- flash drying, intermediate drying and hardening are to be understood as meaning the term contents familiar to the person skilled in the art in connection with processes for producing multicoat paint systems.
- venting understood basically as a name for the evaporation or evaporation of organic solvents and / or water of a coating applied during the preparation of a coating coating at most ambient temperature (ie room temperature), for example 15 to 35 ° C. for a duration of, for example, 0.5 to 30 minutes.
- ambient temperature ie room temperature
- organic solvents and / or water which are contained in the applied coating agent evaporate.
- the coating material since the coating material is still flowable directly after application and at the beginning of venting, it can run during the venting process. Because at least one applied by spray application coating agent is usually applied droplet-shaped and not in a homogeneous thickness.
- the coating layer is not yet ready for use after it has been flashed off. It is, for example, no longer flowable, but still soft or sticky, possibly only dried. In particular, the coating layer is not yet cured as described below.
- Intermediate drying is therefore also understood to mean the evaporation or evaporation of organic solvents and / or water of a coating agent applied during the production of a coating, usually at a temperature of, for example, 40 to 90 ° C., higher than the ambient temperature, for a duration of, for example, 1 to 60 min. Even with intermediate drying, the applied coating agent will thus lose a proportion of organic solvents and / or water. With respect to a particular coating agent is generally considered that the intermediate drying in comparison to bleeding at, for example, higher temperatures and / or for a longer period of time is done, so compared to bleeding and a higher proportion of organic solvents and / or water from the escaped coating layer escapes.
- the coating agent can already be crosslinked or intertwined with one another as a binder as described below.
- a proportion of the polymers contained in the coating agent can already be crosslinked or intertwined with one another as a binder as described below.
- no ready-to-use coating layer is obtained, as is the case with the curing described below.
- curing is clearly differentiated from flash off and intermediate drying.
- hardening of a coating layer is understood to mean the transfer of such a layer into the ready-to-use state, that is to say into a state in which the substrate equipped with the respective coating layer can be transported, stored and used as intended.
- a cured coating layer is thus no longer particularly soft or sticky, but conditioned as a solid coating film, which no longer substantially changes its properties such as hardness or adhesion to the substrate even upon further exposure to curing conditions as described below.
- coating compositions can basically be cured physically and / or chemically, depending on the constituents contained, such as binders and crosslinking agents.
- thermal-chemical curing and actinic-chemical hardening may be considered.
- a coating composition may, for example if it is thermally-chemically curable, be self-crosslinking and / or externally-crosslinking.
- a coating agent is self-crosslinking and / or externally crosslinking, it is to be understood in the context of the present invention that this coating composition contains polymers as binders and optionally crosslinking agents which can crosslink together accordingly.
- the underlying Mechanisms as well as usable binders and crosslinking agents are described below.
- thermally curable or the term “physical curing” means the formation of a cured coating layer by release of solvent from polymer solutions or polymer dispersions, the curing being achieved by entanglement of polymer chains.
- Such coating compositions are usually formulated as one-component coating compositions.
- thermalally-chemically curable or the term “thermal-chemical curing” means the crosslinking of a lacquer layer initiated by chemical reaction of reactive functional groups (formation of a hardened coating layer), the energetic activation of this chemical reaction by thermal energy is possible.
- different functional groups which are complementary to one another can react with one another (complementary functional groups) and / or the formation of the hardened layer is based on the reaction of autoreactive groups, that is to say functional groups which react with each other with groups of their type.
- suitable complementary reactive functional groups and autoreactive functional groups are known, for example, from German Patent Application DE 199 30 665 A1, page 7, line 28, to page 9, line 24.
- This crosslinking can be a self-crosslinking and / or an external crosslinking. If, for example, the complementary reactive functional groups are already present in an organic polymer used as a binder, for example a polyester, a polyurethane or a poly (meth) acrylate, self-crosslinking is present.
- Crosslinking is present, for example, when a (first) organic polymer containing certain functional groups, for example hydroxyl groups, reacts with a crosslinking agent known per se, for example a polyisocyanate and / or a melamine resin.
- the crosslinking agent thus contains reactive functional groups which are identical to those used in the Binder used (first) organic polymer are complementary to existing reactive functional groups.
- the components to be crosslinked for example organic polymers as binders and crosslinking agents, are present next to one another, that is to say in one component.
- the prerequisite for this is that the components to be crosslinked react with one another only at relatively high temperatures of, for example, above 100 ° C., that is, undergo curing reactions. Otherwise, the components to be crosslinked would have to be stored separately from one another and mixed with one another shortly before application to a substrate, in order to avoid premature, at least proportional, thermochemical curing (compare two-component systems).
- hydroxy-functional polyesters and / or polyurethanes with melamine resins and / or blocked polyisocyanates may be mentioned as crosslinking agents.
- the components to be crosslinked for example the organic polymers as binders and the crosslinking agents, are present separately from one another in at least two components which are combined only shortly before application.
- This shape is chosen when the components to be crosslinked react with each other already at ambient temperatures or slightly elevated temperatures of, for example, 40 to 90 ° C.
- hydroxy-functional polyesters and / or polyurethanes and / or poly (meth) acrylates with free polyisocyanates as crosslinking agents may be mentioned.
- an organic polymer has as binder both self-crosslinking and externally crosslinking functional groups and then combined with crosslinking agents.
- actinic-chemical hardening or the term “actinic-chemical curing” is to be understood as meaning the hardening using actinic radiation, namely electromagnetic radiation such as near infrared (NIR) and UV radiation, in particular UV radiation, as well as corpuscular radiation such as electron radiation for curing is possible.
- UV radiation is usually initiated by free-radical or cationic photoinitiators.
- Typical actinically curable functional groups are carbon-carbon double bonds, which usually radical photoinitiators are used. The actinic hardening is therefore also based on a chemical crosslinking.
- curing is effected by different mechanisms, which of course also make different conditions necessary during the curing, in particular different curing temperatures and curing times.
- curing preferably takes place between 15 and 90 ° C. over a period of 2 to 48 hours.
- the curing of flash-off and / or intermediate drying thus differs possibly only by the duration of the conditioning of the coating layer.
- a differentiation between flash off and intermediate drying is also not useful. It would be possible, for example, first to ventilate or temporarily dry a coating layer produced by applying a physically curable coating composition at 15 to 35 ° C. for a period of, for example, 0.5 to 30 minutes and then to cure at 50 ° C. for a period of 5 hours.
- the coating materials to be used in the process according to the invention are preferably thermally-chemically curable, more preferably thermally-chemically curable and externally crosslinking.
- the curing of thermally-chemically curable one-component systems preferably takes place at temperatures of 100 to 250 ° C., preferably 100 to 180 ° C. for a period of 5 to 60 minutes, preferably 10 to 45 min is carried out, since these conditions are usually necessary to convert the coating layer by chemical crosslinking reactions in a cured coating layer.
- a pre-cure buffing and / or intermediate drying phase occurs at lower temperatures and / or for shorter times.
- it may be flashed off at 15 to 35 ° C for a period of, for example, 0.5 to 30 minutes, and / or intermediately dried at a temperature of, for example, 40 to 90 ° C for a period of, for example, 1 to 60 minutes.
- the curing of thermally-chemically curable two-component systems at temperatures of, for example, 15 to 90 ° C, preferably 40 to 90 ° C for a period of 5 to 80 min, preferably 10 to 50 min is carried out.
- a pre-cure buffing and / or intermediate drying phase occurs at lower temperatures and / or for shorter times.
- a pre-curing or intermediate drying phase can, for example, take place at 15 to 35 ° C. for a period of, for example, 0.5 to 30 minutes, but at any rate at lower temperatures and / or for shorter times than the subsequent curing.
- thermally-chemically curable two-component system is cured at higher temperatures.
- a basecoat or multiple basecoat films cured together with a clearcoat. If both thermally-chemically curable one-component and two-component systems are present within the layers, for example a one-component basecoat and a two-component clearcoat, the joint curing is of course determined by the curing conditions necessary for the one-component system.
- a multicoat system is built up on a metallic substrate (S).
- Substrates containing or consisting of, for example, iron, aluminum, copper, zinc, magnesium and their alloys, as well as steel in a wide variety of shapes and compositions are generally suitable as metallic substrates (S).
- S metallic substrates
- Preferred are iron and steel substrates, for example typical iron and steel substrates as used in the automotive industry.
- the substrates can be shaped as desired, that is, it can be, for example, simple sheets or even complex components such as in particular car bodies and parts thereof.

- the electrodeposition paint (e.1) used in step (1) of the process according to the invention may be a cathodic or anodic electrodeposition paint. It is preferably a cathodic electrodeposition paint.
- Electrocoating paints have long been known to the skilled person. These are aqueous coating materials which contain anionic or cationic polymers as binders. These polymers contain functional groups that are potentially anionic, that is, that can be converted into anionic groups, for example, carboxylic acid groups, or functional groups that are potentially cationic, that is, that can be converted into cationic groups, for example, amino groups.
- the conversion into charged groups is usually achieved by the use of appropriate neutralizing agents (organic amines (anionic), organic carboxylic acids such as formic acid (cationic)), which then produce the anionic or cationic polymers.
- the electrocoating paints contain typical anti-corrosive pigments.
- the cathodic electrodeposition paints preferred in the context of the invention preferably comprise cationic polymers as binders, in particular hydroxy-functional polyetheramines, which preferably have aromatic structural units. Such polymers are used in the rule by reacting corresponding bisphenol-based epoxy resins with amines such as mono- and dialkylamines, alkanolamines and / or Dialkylaminoalkylamine obtained.
- the electrodeposition coating (e.1) is therefore preferably a thermally-chemically curable coating composition, in which case it is in particular externally crosslinking.
- the electrocoat material (e.1) is preferably a thermally-chemically curable one-component coating composition.
- the electrocoating (e.1) contains a hydroxy-functional epoxy resin as a binder and a fully blocked polyisocyanate as a crosslinking agent.
- the epoxy resin is preferably cathodic, in particular containing amino groups.
- the workpiece acts as an electrode which migrates non-volatile constituents of the electrodeposition paint due to the described charge of the polymers used as binders through the electric field to the substrate and deposit on the substrate, whereby an electrodeposition coating layer is formed.
- the substrate is thus connected as a cathode, where the hydroxide ions formed there by the electrolysis of water neutralize the cationic binder, so that it is deposited on the substrate and forms an electrodeposition coating. It is then an application by the electrophoretic dipping method.
- the coated substrate (S) is removed from the basin, optionally with, for example, water-based rinsing solutions rinsed, then optionally flashed off and / or intermediately dried, and finally the applied electrodeposition paint is cured.

- the electrodeposition coating (e.1) is a thermo-chemically curable one-component coating composition as described above.
- the electrodeposition coating is a curable coating agent in other ways and / or other Abllust-, embrocknungs- and curing conditions are used.
- the layer thickness of the cured electrodeposition coating layer is, for example, 10 to 40 micrometers, preferably 15 to 25 micrometers. All layer thicknesses specified in the context of the present invention are understood as dry layer thicknesses. It is therefore the layer thickness of the respective cured layer. If, therefore, it is stated that a lacquer is applied in a certain layer thickness, it is to be understood that the lacquer is applied in such a way that the said layer thickness results after hardening.
- step (2) of the process according to the invention (2.1) a basecoat film (B.2.1) is prepared or (2.2) several directly successive basecoat films (B.2.2.x) are prepared.
- the layers are produced by applying (2.1) a aqueous basecoat (b.2.1) directly to the cured electrodeposition coating layer (E.1) or (2.2) directly successive application of several basecoats (b.2.2.x) to the cured electrodeposition coating layer (E.1).
- the directly successive application of several basecoats (b.2.2.x) to the cured electrodeposition coating layer (E.1) is thus understood to mean that first a first basecoat is applied directly to the electrodeposition coat and then a second basecoat is applied directly to the layer of the first base coat is applied. An optionally third basecoat is then applied directly to the layer of the second basecoat. This process can then be repeated analogously for further basecoats (ie a fourth, fifth, etc. basecoat).
- the basecoat film (B.2.1) or the first basecoat film (B.2.2.x) is thus arranged directly on the cured electrodeposition coating (E.1) after production.
- the terms basecoat and basecoat film in relation to the coating agents and coating layers applied in step (2) of the process of the invention are used for the sake of clarity.
- the basecoat films (B.2.1) and (B.2.2.x) are not cured separately, but cured together with the clearcoat. Curing thus takes place analogously to the curing of so-called basecoats used in the standard method described in the introduction.
- the coating compositions used in stage (2) of the process according to the invention are not hardened separately, as are the coating compositions designated as fillers in the standard process.
- the aqueous basecoat (b.2.1) used in step (2.1) is described in detail below. In a first preferred embodiment, however, it is at least thermally-chemically curable, particularly preferably externally crosslinking.
- the basecoat (b.2.1) is preferably a one-component coating agent.
- the basecoat material (b.2.1) preferably comprises a combination of at least one hydroxyl-functional polymer as binder selected from the group consisting of polyurethanes, polyesters, polyacrylates and copolymers of said polymers, For example, polyurethane polyacrylates, and at least one melamine resin as a crosslinking agent.
- This embodiment of the invention is particularly suitable if, for example, an exceptionally good bonding adhesion of the multi-layer coating according to the invention should result.

This results clearly and directly from the below described step (4) of the method according to the invention. Since the basecoat film is only cured in stage (4), it can not be cured in stage (2), because then curing in stage (4) would no longer be possible.
- aqueous basecoats (b.2.2.x) used in step (2.2) of the process according to the invention are also described in detail below.

- it is equally possible and thus likewise a preferred embodiment to use at least one basecoat (b.2.2.x) which only contains small amounts of less than 5% by weight, preferably less than 2.5% by weight.
- the basecoats (b.2.2.x) can be applied by the methods known to those skilled in the art for the application of liquid coating compositions, for example by dipping, knife coating, spraying, rolling or the like.

- the basecoats (b.2.2.x) are applied via the pneumatic spray application and / or the electrostatic spray application.
- the basecoats and basecoats are generally characterized by (b.2.2.x) and (B.2.2.x), while in naming the specific individual basecoats and basecoats, the x can be replaced by correspondingly appropriate other letters.
- the first basecoat and the first basecoat film can be labeled a, the topmost basecoat and the topmost basecoat film can be labeled z. These two basecoats or basecoats are present in the stage (2.2) in any case.
- Optionally interposed layers may be consecutively labeled b, c, d and so on.
- a basecoat film (B.2.2.a) is thus produced directly on the cured electrodeposition paint film (E.1).

- exactly one further basecoat film (B.2.2.x) can be produced, this then being disposed in the finally produced multicoat paint system directly below the clearcoat film (K) and thus being referred to as the basecoat film (B.2.2.z) (cf. also Figure 2).
- the basecoats (b.2.2.x) can be identical or different. It is also possible to produce several basecoat films (B.2.2.x) with the same basecoat and one or more further basecoat films (B.2.2.x) with one or more other basecoats.

- the application is obviously carried out in two stages, so that the corresponding basecoat in the sense of the method according to the invention corresponds to a first basecoat (b.2.2.a) and another basecoat (b.2.2.z).
- the described construction is often also referred to as a single-layer basecoat layer structure produced in two jobs. Since, however, due to the technical conditions in a paint shop between the first job and the second job, a certain period of time always elapses, during which the substrate, for example the automobile body, is conditioned at, for example, 15 to 35 ° C. and thus vented, the characterization of this structure as a two-layer basecoat construction is formally more distinct.

- the basecoat material (b.2.1) to be used according to the invention comprises at least one, preferably exactly one, specific aqueous polyurethane-polyurea dispersion (PD).

- the system is a dispersion containing discrete particles with a measurable mean particle size, but due to their molecular nature, they are dissolved in suitable organic solvents, whereas macroscopic networks would only be swollen.
- the microgels represent structures that are between branched and macroscopically crosslinked systems, thus combining the characteristics of suitable organic solvent-soluble macromolecules with network structure and insoluble macroscopic networks, the proportion of crosslinked polymers may not change until after isolation of the solid polymer Water and optionally organic solvents and subsequent extraction can be determined. It makes use of the fact that the originally soluble in suitable organic solvents microgel particles retain their internal network structure after isolation and behave in the solid as a macroscopic network. The crosslinking can be checked via the experimentally accessible gel fraction. Ultimately, the gel fraction is the fraction of the polymer from the dispersion which, as an isolated solid, can not be dissolved in a solvent in a molecularly disperse manner.
- the polyurethane-polyurea particles contained in the aqueous polyurethane-polyurea dispersion (PD) preferably have a gel content of at least 60%, more preferably of at least 70%, particularly preferably of at least 80%.

- the polyisocyanates are generally reacted to form urethanes with polyols, especially diols.
- suitable polyols are saturated or olefinically unsaturated polyester polyols and / or polyether polyols.
- polyester polyols in particular those having a number average molecular weight of 400 to 5000 g / mol (method of measurement see example), are used.
- polyester polyols preferably polyester diols
- polyester diols can be prepared in known manner by reaction of corresponding polycarboxylic acids, preferably dicarboxylic acids, and / or their anhydrides with corresponding polyols, preferably diols, by esterification.
- monocarboxylic acids and / or monoalcohols may also be used proportionately for the preparation.
- the polyester diols are preferably saturated, in particular saturated and linear.
- polyester polyols preferably polyester diols
- phthalic acid isophthalic acid and terephthalic acid, of which isophthalic acid is advantageous and is therefore preferably used.

- Dicarboxylic acids which can also be used are dimer fatty acids or dimerized fatty acids, which are known to be mixtures which are prepared by dimerization of unsaturated fatty acids and can be obtained, for example, under the trade names Radiacid (Oleon) or Pripol (Croda).
- the use of such dimer fatty acids for the preparation of polyester diols is preferred in the context of the present invention.
- Preferably used polyols for the preparation of prepolymers (Z.1 .1) are thus polyester diols which have been prepared using dimer fatty acids.
- Particular preference is given to polyester diols, in the preparation of which at least 50% by weight, preferably 55 to 75% by weight, of the dicarboxylic acids used are dimer fatty acids.
- polyester polyols examples include ethylene glycol, 1, 2 or 1, 3-propanediol, 1, 2, 1, 3 or 1, 4 Butanediol, 1, 2, 1, 3, 1, 4- or 1, 5-pentanediol, 1, 2, 1, 3, 1, 4, 1, 5 or 1, 6-hexanediol, hydroxypivalates , Neopentyl glycol, diethylene glycol, 1, 2-, 1, 3- or 1, 4-cyclohexanediol, 1, 2-, 1, 3- or 1, 4-cyclohexanedimethanol and trimethylpentanediol. Preference is therefore given to using diols.
- Such polyols or diols can of course also be used directly for the preparation of the prepolymer (Z.1 .1), that is to say reacted directly with polyisocyanates.
- polyamines such as diamines and / or amino alcohols for the preparation of the prepolymers (Z.1 .1).
- diamines hydrazine, alkyl or Cycloalkyldiamine such as propylene diamine and 1-amino-3-aminomethyl-3,5,5-trimethylcyclohexane and as amino alcohols ethanolamine or diethanolamine.
- the prepolymers (Z.1 .1) contain anionic and / or anionic groups convertible groups.
- starting compounds can be used in the preparation of the prepolymers (Z.1 .1) which, in addition to groups to be reacted in the preparation of urethane bonds, preferably hydroxyl groups, also contain the abovementioned groups, for example carboxylic acid groups. In this way, the corresponding groups are introduced into the prepolymer.
- Suitable compounds for introducing the preferred carboxylic acid groups, if containing carboxyl groups are polyether polyols and / or polyester polyols.
- the expression "low molecular weight compound” is to be understood as meaning, in contrast to relatively high molecular weight compounds, in particular polymers, those to which a discrete molecular weight can be assigned as preferably monomeric compounds, ie a low molecular weight compound is in particular no polymer, because the latter always represent a mixture of molecules and must have average molecular weights to be discribed.
- the term low molecular weight compound is preferably to be understood as meaning that the corresponding compounds have a molecular weight of less than 300 g / mol. Preferably, the range is from 100 to 200 g / mol.
- Preferred compounds in this sense are, for example, monocarboxylic acids containing two hydroxyl groups, for example dihydroxypropionic acid, dihydroxysuccinic acid and dihydroxybenzoic acid.
- alpha, alpha dimethylolalkanoic acids such as 2,2-dimethylolacetic acid, 2,2-dimethylolpropionic acid, 2,2-dimethylolbutyric acid and 2,2-dimethylolpentanoic acid, in particular 2,2-dimethylolpropionic acid.
- the prepolymers (Z.1 .1) are therefore preferably carboxy-functional. They have, based on the solids, preferably an acid number of 10 to 35 mg KOH / g, in particular 15 to 23 mg KOH / g.
- the number-average molecular weight of the prepolymers can vary widely and is for example in the range from 2000 to 20 000 g / mol, preferably from 3500 to 6000 g / mol (measuring method see example part).
- the prepolymer (Z.1 .1) is isocyanate group-containing. It preferably has, based on the solids, an isocyanate content of 0.5 to 6.0 wt .-%, preferably 1, 0 to 5.0 wt .-%, particularly preferably 1, 5 to 4.0 wt .-% (Measurement method it sample part).
- the hydroxyl value of the prepolymer will, as a rule, be very low.
- the hydroxyl number of the prepolymer, based on the solids, is preferably less than 15 mg KOH / g, in particular less than 10 mg KOH / g, more preferably less than 5 mg KOH / g (measuring method see example).
- the preparation of the prepolymers (Z.1 .1) can be carried out by known and established methods in bulk or solution, particularly preferably by reacting the starting compounds in organic solvents, such as preferably methyl ethyl ketone Temperatures of for example 60 to 120 ° C, and optionally using catalysts typical for polyurethane production. Such catalysts are known to the person skilled in the art, an example being dibutyltin laurate. It is of course to proceed so that the ratio of the starting components is selected so that the product, that is, the prepolymer (Z.1 .1) contains isocyanate groups.
- organic solvents such as preferably methyl ethyl ketone
- the solvents should be selected so that they do not undergo any undesired reactions with the functional groups of the starting compounds, ie are inert to these groups insofar as they do not hinder the reaction of these functional groups.
- the preparation is preferably already carried out in an organic solvent (Z.2) as described below, since this must be present in any case in the composition (Z) to be prepared in stage (I) of the process.
- the groups which can be converted into anionic groups in the prepolymer (Z.1 .1) can also be present proportionally as corresponding anionic groups, for example by the use of a neutralizing agent. In this way, the water-dispersibility of the prepolymers (Z.1 .1) and thus also of the intermediate (Z.1) can be adjusted.
- Suitable neutralizing agents are, in particular, the known basic neutralizing agents, such as, for example, carbonates, bicarbonates or hydroxides of alkali metals and alkaline earth metals, for example LiOH, NaOH, KOH or Ca (OH) 2.
- suitable for neutralization and preferably used in the context of the present invention are organic, nitrogen-containing bases such as amines such as ammonia, trimethylamine, triethylamine, tributylamines, dimethylaniline, triphenylamine, dimethylethanolamine, methyldiethanolamine or triethanolamine and mixtures thereof.
- the neutralizing agent can also already be added during or before the beginning of the actual polymerization, in which case, for example, the carboxylic acid group-containing starting compounds are neutralized.
- the neutralizing agent may be added, for example, in such an amount that a proportion of 35 to 65% of the groups is neutralized (degree of neutralization). A range of 40 to 60% is preferred (calculation method see example part). It is preferred that the prepolymer (Z.1 .1) after its preparation and before its use for the preparation of the intermediate (Z.1) is neutralized as described.
- the preparation of the intermediate (Z.1) described here comprises the reaction of the described prepolymer (Z.1 .1) with at least one, preferably exactly one polyamine (Z.1.2a) derived from a polyamine (Z.1.2) ,
- the polyamine (Z.1.2a) contains two masked primary amino groups and one or two free secondary amino groups.
- masked amino groups are to be understood as those in which the hydrogen radicals, which are present in free amino groups, are substituted on the nitrogen by reversible reaction with a masking agent. Due to the masking, the amino groups can not be reacted as free amino groups via condensation or addition reactions, so are not reactive in this regard and thus differ from free amino groups. Only the removal again of the reversibly attached masking agent, which in turn gives rise to the free amino groups, then evidently allows the known per se reactions of the amino groups. The principle thus resembles the principle of blocked or masked isocyanates likewise known in the field of polymer chemistry.
- the primary amino groups of the polyamine ⁇ ZA .2a) can be masked with the masking agents known per se, for example with ketones and / or aldehydes. With such a masking, ketimines and / or aldimines which do not contain any nitrogen-hydrogen bonds are thus formed, with the release of water, so that no typical condensation or addition reactions of an amino group with another functional group such as an isocyanate group can take place.
- Reaction conditions for preparing such a masked primary amine for example a ketimine
- a corresponding masking can be realized.
- the resulting water of reaction is removed during the reaction to prevent the otherwise possible reverse reaction (unmasking) of the reversible masking.
- the reaction conditions for unmasking masked primary amino groups are known per se.
- the conversion of a masked amine into the aqueous phase is sufficient to shift the equilibrium back to the side of the unmasking by the then existing concentration pressure of the water, thereby producing primary amino groups free of water and a free ketone.
- Preferred masking agents for masking the primary amino groups of the polyamine (Z.1.2a) are ketones.
- ketones particularly preferred are those which are an organic solvent (Z.2) as described below.
- solvents (Z.2) must be present anyway in the composition (Z) to be prepared in step (I) of the process.
- the use of ketones (Z.2) for masking therefore makes it possible to use the correspondingly preferred production process of masked amines without the possibly undesired masking agent having to be removed in a complicated manner. Instead, the masked amine solution can be used directly to prepare the intermediate (Z.1).
- Preferred masking agents are acetone, methyl ethyl ketone, methyl isobutyl ketone, diisopropyl ketone, cyclopentanone or cyclohexanone, particularly preferably the ketones (Z.2) are methyl ethyl ketone and methyl isobutyl ketone.
- the preferred masking with ketones and / or aldehydes, in particular ketones, and the resulting production of ketimines and / or aldimines also has the advantage that selectively primary amino groups are masked. Existing secondary amino groups apparently can not be masked and thus remain free.
- a polyamine (Z.1.2a) which also contains one or two free secondary amino groups in addition to the two masked primary amino groups, easily via the said preferred masking reactions of a polyamine (Z.1 .2), which free secondary and primary Contains amino groups can be prepared.
- the polyamines (Z.1.2a) can be prepared by masking the primary amino groups of polyamines (Z.1.2) containing two primary amino groups and one or two secondary amino groups.
- any desired aliphatic, aromatic or araliphatic groups can be present.
- monovalent groups arranged as terminal groups on a secondary amino group or divalent groups arranged between two amino groups are possible.
- aliphatic is understood as meaning all organic groups which are not aromatic.
- aliphatic hydrocarbon groups that is groups which consist exclusively of carbon and hydrogen and are not aromatic.
- These aliphatic hydrocarbon groups may be linear, branched or cyclic, which may be saturated or unsaturated. Of course, these groups may also contain both cyclic and linear or branched portions. It is also possible that aliphatic groups contain heteroatoms, in particular in the form of bridging groups such as ether, ester, amide and / or urethane groups. Possible aromatic groups are also known and require no further explanation.
- the polyamines (Z.1 .2a) have two masked primary amino groups and one or two free secondary amino groups and they have as primary amino groups exclusively masked primary amino groups and as secondary amino groups exclusively free secondary amino groups.
- the polyamines (Z.1.2a) have a total of three or four amino groups, these being selected from the group of the masked primary amino groups and the free secondary amino groups.
- Very particularly preferred polyamines are those which consist of two masked primary amino groups, one or two free secondary amino groups and aliphatic-saturated hydrocarbon groups.
- Examples of preferred polyamines (Z.1.2) from which polyamines (Z.1.2a) can also be prepared by masking the primary amino groups are diethylenetriamine, 3- (2-aminoethyl) aminopropylamine, dipropylenetriamine and N1- (2 (4- (2-aminoethyl) piperazin-1-yl) ethyl) ethane-1,2-diamine (one secondary amino group, two primary amino groups to be blocked) and triethylenetetramine and N, N'-bis (3-amino) aminopropyl) ethylenediamine (two secondary amino groups, two primary amino groups to be blocked).
- the preparation of the intermediate (Z.1) comprises the reaction of the prepolymer (Z.1.1) with the polyamine (Z.1.2a) by addition reaction of isocyanate groups (Z.1.1) with free secondary amino groups (Z. .1 .2a).
- This reaction which is known per se, then leads to the binding of the polyamine (Z.1 .2a) to the prepolymer (Z.1 .1) to form urea bonds, whereby ultimately the intermediate (Z.1) is formed.
- preferably no other amines with free or masked secondary or free or masked primary amino groups are used.
- the preparation of the intermediate (Z.1) can be carried out by known and established methods in bulk or solution, in particular preferably by reaction of (Z.1 .1) with (Z.1.2a) in organic solvents. It is immediately apparent that the solvents should be selected such that they do not undergo any undesired reactions with the functional groups of the starting compounds, ie that they are inert or largely inert towards these groups.
- the solvent used in the preparation is preferably at least partly an organic solvent (Z.2), in particular methyl ethyl ketone, as described below, since this must be present in any case in the composition (Z) to be prepared in step (I) of the process.
- a solution of a prepolymer (Z.1 .1) in a solvent (Z.2) is preferably mixed with a solution of a polyamine (Z.1 .2a) in a solvent (Z.2), the reaction described taking place can.
- the intermediate (Z.1) prepared in this way can be neutralized during or after the preparation with neutralizing agents already described above in the manner also described above for the prepolymer (Z.1 .1).
- the prepolymer (Z.1 .1) is already neutralized in the manner described above prior to its use for the preparation of the intermediate (Z.1), so that neutralization during or after the preparation of (Z.1) is not is more relevant.
- the degree of neutralization of the prepolymer (Z.1 .1) must be equated with the degree of neutralization of the intermediate (Z.1). If no further addition of neutralizing agents is carried out in the course of the process, the degree of neutralization of the polymers present in the finally prepared inventive dispersions (PD) must be equated with the degree of neutralization of the prepolymer (Z.1 .1).
- the intermediate (Z.1) has masked primary amino groups. This is evidently achieved by reacting the prepolymer (Z.1.1) and the polyamine (Z.1.2a) to react the free secondary amino groups, but not to react the masked primary amino groups. As already described above, masking ensures that no typical condensation or addition reactions with other functional groups such as isocyanate groups can take place. Of course, this means that the conditions in the reaction are to be chosen so that the masked amino groups remain masked, thereby providing an intermediate (Z.1). Appropriate The expert knows how to adjust conditions and is realized, for example, by the already preferred reaction in organic solvents.
- the intermediate (Z.1) is isocyanate group-containing. Accordingly, in the reaction of (Z.1 .1) and (Z.1 .2a), the ratio of these components must, of course, be chosen such that the product, ie the intermediate (ZA), contains isocyanate groups.
- the intermediate (Z.1) formed by reacting isocyanate groups of (Z.1.1) with the free secondary amino groups of (Z.1.2a) has an excess relative to the masked primary amino groups of isocyanate groups. This is ultimately achieved by selecting the molar ratio of isocyanate groups of (Z.1.1) to the total amount of free secondary amino groups and masked primary amino groups of (Z.1.2a) to be such that even after the preparation of (Z.1) and the corresponding consumption of isocyanate groups by the reaction with the free secondary amino groups remains a corresponding excess of the isocyanate groups.
- the polyamine (Z.1.2a) has a free secondary amino group and two masked primary amino groups
- the molar ratio between the isocyanate groups of (Z.1.1) to the polyamine (Z.1.2a) in the whole particularly preferred embodiment set with 5/1.
- the consumption of an isocyanate group in the reaction with the free secondary amino group would then mean that for the above-mentioned condition 4/2 (or 2/1) is realized.
- the proportion of the intermediate (Z.1) is from 15 to 65 wt .-%, preferably from 25 to 60 wt .-%, more preferably from 30 to 55 wt .-%, particularly preferably from 35 to 52.5 wt. -% and in a very particular embodiment from 40 to 50 wt .-%, each based on the total amount of the composition (Z).
- the determination of the proportion of an intermediate (Z.1) can be carried out as follows: The solid of a mixture which contains only organic solvents in addition to the intermediate (Z.1) is determined (measurement method for determination of the solid (also solids content or solids content) called) see example). The solid then corresponds to the amount of the intermediate (Z.1). By taking into account the solids of the mixture, the proportion of the intermediate (Z.1) in the composition (Z) can thus be determined or determined. Since the intermediate (Z.1) is preferably already produced in an organic solvent, that is to say it is anyway present in a mixture after preparation, which contains only organic solvents in addition to the intermediate, this is the method of choice.
- composition (Z) also contains at least one special organic solvent (Z.2).
- the solvents (Z.2) have a solubility in water of not more than 38% by weight at a temperature of 20 ° C. (measuring method see example part).
- the solubility in water at a temperature of 20 ° C is less than 30 wt .-%.
- a preferred range is from 1 to 30% by weight. Accordingly, the solvent (Z.2) has a rather moderate solubility in water, in particular is not completely miscible with water or has no unlimited solubility in water. Fully miscible with water is a solvent when it can be mixed in any proportions with water, without causing a segregation, that is two-phase formation.
- solvents (Z.2) are methyl ethyl ketone, methyl isobutyl ketone, diisobutyl ketone, diethyl ether, dibutyl ether, dipropylene glycol dimethyl ether, ethylene glycol diethyl ether, toluene, methyl acetate, ethyl acetate, butyl acetate, propylene carbonate, cyclohexanone or mixtures of these solvents.
- No solvents (Z.2) are thus solvents such as acetone, N-methyl-2-pyrrolidone, N-ethyl-2-pyrrolidone, tetrahydrofuran, dioxane, N-formylmorpholine, dimethylformamide or dimethylsulfoxide.
- the selection of the special solvents (Z.2) with only limited solubility in water achieves, in particular, that a homogeneous solution can not be formed directly in the aqueous phase in the dispersion of the composition (Z) in step (II) of the process. It is believed that the present dispersion allows the crosslinking reactions (addition reactions of free primary amino groups and isocyanate groups to form urea linkages) proceeding under step (II) to proceed in limited volumes, ultimately allowing the formation of the microparticles as defined above.
- Preferred solvents (Z.2) in addition to the described water solubility have a boiling point of at most 120 ° C, more preferably of at most 90 ° C (at atmospheric pressure, that is 1, 013 bar).
- step (III) of the process is to say the at least partial removal of the at least one organic solvent (Z.2) from the dispersion which is prepared in step (II) of the process.
- these solvents can be removed, for example, by distillation be removed without the simultaneous significant amounts of the introduced in step (II) of the process water.
- step (PD) eliminates the costly yielding of water to obtain the aqueous character of the dispersion (PD).
- the proportion of the at least one organic solvent (Z.2) is from 35 to 85 wt .-%, preferably from 40 to 75 wt .-%, more preferably from 45 to 70 wt .-%, particularly preferably from 47.5 to 65 wt .-% and in a very particular embodiment of 50 to 60 wt .-%, each based on the total amount of the composition (Z).
- the described components (Z.1) and (Z.2) in total preferably make up at least 90% by weight of the composition (Z).
- the two components preferably make up at least 95% by weight, in particular at least 97.5% by weight, of the composition (Z).
- the composition (Z) consists of these two components.
- these neutralizing agents are included in the calculation of the amount of an intermediate (Z.1) the intermediate.
- the intermediate (Z.1) in any case has anionic groups, which go back to the use of the neutralizing agent. The cation present after the formation of these anionic groups is therefore likewise attributed to the intermediate.
- the composition (Z) contains other components in addition to the components (Z.1) and (Z.2), these are preferably only organic Solvents.
- the solid of the composition (Z) thus corresponds to the proportion of the intermediate (Z.1) in the composition (Z).
- the composition (Z) thus preferably has a solids content of 15 to 65 wt .-%, preferably from 25 to 60 wt .-%, more preferably from 30 to 55 wt .-%, particularly preferably from 35 to 52.5 wt. % and in a very particular embodiment from 40 to 50% by weight.
- a particularly preferred composition (Z) thus contains in total at least 90% by weight of the components (Z.1) and (Z.2) and contains, in addition to the intermediate (Z.1), exclusively organic solvents.
- composition (Z) An advantage of the composition (Z) is that it can be prepared without the use of environmentally and harmful organic solvents such as N-methyl-2-pyrrolidone, dimethylformamide, dioxane, tetrahydrofuran and N-ethyl-2-pyrrolidone. Accordingly, the composition (Z) preferably contains less than 10 wt .-%, preferably less than 5 wt .-%, more preferably less than 2.5 wt .-% of organic solvents selected from the group consisting of N-methyl-2 - pyrrolidone, dimethylformamide, dioxane, tetrahydrofuran and N-ethyl-2-pyrrolidone. Preferably, the composition (Z) is completely free of these organic solvents.
- composition (Z) is dispersed in aqueous phase.
- step (II) a demasking of the masked primary amino groups of the intermediate (Z.1) is thus realized in step (II). Because the conversion of a masked amine into the aqueous phase releases the reversibly attached masking agent while consuming water, and free primary amino groups are formed. It is also clear that the resulting free primary amino groups then also present with isocyanate groups of the intermediate (Z.1) or the unmasked from the intermediate (Z.1) unmasked intermediate by addition reaction to form urea bonds are reacted.
- step (II) of the process described here the composition (Z) is dispersed in water, wherein a unmasking of the masked primary amino groups of the intermediate (Z.1) and a reaction of the resulting free primary amino groups with the isocyanate groups of the intermediate (Z. 1) and the isocyanate groups of the demasked intermediate formed from the intermediate (Z.1) by addition reaction.
- Step (II) of the process described here that is, the dispersion in the aqueous phase
- the composition (Z) can be carried out in any desired manner.
- the composition (Z) which may be present after preparation, for example, at room temperature, that is 20 to 25 ° C, or at room temperature increased temperature, for example, 30 to 60 ° C, are stirred into water, whereby a dispersion is formed.
- the water introduced, for example, has room temperature. It can be dispersed in pure water (deionized water), that is, the aqueous phase consists only of water, which is preferred.
- the aqueous phase may also contain proportionate typical auxiliaries, such as typical emulsifiers and protective colloids.
- typical auxiliaries such as typical emulsifiers and protective colloids.
- suitable emulsifiers and protective colloids can be found for example in Houben Weyl, Methods of Organic Chemistry, Volume XIV / 1 Macromolecular substances, Georg Thieme Verlag, Stuttgart 1961, S 41 1 ff.
- step (II) of the process that is, in the dispersion of the composition (Z) in the aqueous phase, the weight ratio of organic solvents and water is chosen so that the resulting dispersion has a weight ratio of water to organic solvents greater than 1, preferably from 1.05 to 2/1, particularly preferably from 1.1 to 1.5 / 1.
- step (III) of the process described here the at least partial removal of the at least one organic solvent (Z.2) takes place from the dispersion obtained in step (II).
- step (III) of the process other solvents, which were present, for example, optionally in the composition (Z), are removed.
- the removal of the at least one organic solvent (Z.2) and optionally further organic solvents can be carried out in any known manner, for example by vacuum distillation at temperatures slightly elevated from room temperature, for example 30 to 60 ° C.

- the proportion of water in the dispersion (PD) is preferably 45 to 75 wt .-%, preferably 50 to 70 wt .-%, more preferably 55 to 65 wt .-%, each based on the total amount of the dispersion.
- the dispersion (PD) to be used according to the invention can be formulated such that it contains at least 85% by weight, preferably at least 90.0% by weight, very particularly preferably at least 95% by weight. and more preferably at least 97.5% by weight of the polyurethane-polyurea particles and water (the associated value being obtained by summation of the amount of the particles (that is the polymer, determined by the solids content) and the amount of water) , It has been shown that the dispersions are in each case very stable, in particular storage-stable, despite this small proportion of other components, in particular organic solvents. This brings together two relevant benefits.
