Description

Waterborne foam wallpaper using natural materials {omitted}

The present invention relates to an aqueous foam wallpaper using a natural material and an aqueous foam material.

As a result of developing and producing the wallpaper using the existing natural materials (Special Publication No. 1998-0019564), various problems occur and suggest a new concept of production method.

Existing biodegradable wallpaper is composed of wallpaper paper-adhesive-biodegradable plaster-top coating layer.

In this way, it is impossible to print the difference in comparison with the general wallpaper (not possible due to the roughness of the surface), and impossibility of the embossing work When painting on the back during construction, a large amount of water is transferred to the natural material, so that the water dissolution time can be extended for a long time (usually, water dissolution time is about 4 to 12 hours, but within 30 minutes to 2 hours for wallpaper using natural materials) When the wallpaper is suitable, if the time elapses, the wallpaper is weak due to moisture and tearing occurs, or the glued back contact surfaces adhere to each other and dry on the adhesive surface during water dissolving work. It is a limiting point for the generalization of the state where the wallpaper construction is impossible due to the transfer of water to the grass).

An aqueous foaming agent is added to the synthetic resin to form a compressed layer under pressure during embossing and to form flatness on the surface to improve printability to provide a new type of wallpaper.

When described in detail according to the accompanying drawings an embodiment of the present invention as follows.

As shown in FIG. 1, the difference between the adhesive of the aqueous foaming agent added to the wallpaper base and the adhesive of the conventional product (biodegradable wallpaper) is that the adhesive of the existing product is any one of acrylic, PE, and EVA-based adhesives 1㎡. Apply about 30-50g of sugar and dry natural materials.

As such, when the general adhesive is used, the above phenomenon occurs when the water is melted by pasting the back of the wallpaper during the construction of the product after the completion of the product.

Such a phenomenon is that general adhesive is not completely formed into film even after it is applied to wallpaper paper and dried, so it is easy to permeate moisture. Also, if film is formed too much, water cannot be melted during construction, which makes it difficult to install wallpaper. Lose. In addition, since there is no pressing layer due to pressure during embossing, there is no embossability.

The present invention solves this problem by forming a foam layer that can be compressed during proper water passage and embossing work, and any one or a mixture of acrylic, EVA, and water-based urethane-based adhesives, 20 to 50% by weight, water 5 to 10 wt%, 5-10 wt% methanol and alcohol, 2-7 wt% aqueous foaming agent, 0.1-0.5 wt% emulsifier, 20-40 wt% Ca Co _3, 5-10 wt% talc and mildew powder, TiO ₂ 2 ~ 5% by weight, 2 ~ 5% by weight of far-infrared radiation such as jade, 0.1 ~ 0.1% by weight of ammonia water, 0.1 ~ 0.2% by weight of thickener, 0.1 ~ 0.5% by weight of dispersant, 0.1 ~ 0.5% by weight of antifoam, etc. Apply about 50 ~ 150g (solid content) per 1㎡ by comma cotta, gravure copper plate and rotary screen method.

At this time, the use of methanol and alcohol in the formulation is used to control the penetration rate of the adhesive to the wallpaper base material and to improve the drying rate, and the use of emulsifiers by adding an aqueous foaming agent in the gelling operation (drying) and the liquidity of the liquid during mixing Non-ionic emulsifier, anionic emulsifier, cationic emulsifier, amphoteric emulsifier can be used, and water-based foaming agent uses aqueous foaming agent filled with GAS such as isobutane, iso, pentane, etc. The use of the radioactive material is applied to the wallpaper base with comma-cotta, gravure roll, rotary screen, etc., and then only the surface of the water-based foam toner is dried first due to the high temperature heat of the drying oven during gelling. Ideally the coated surface will swell or foam non-uniformity of the aqueous foaming agent will occur.

This phenomenon occurs because only the surface is dried first and the moisture inside can not evaporate. In order to solve such a phenomenon, the present invention adds far-infrared radiation materials such as elite, jade, elvan, ceramic, feldspar, zeolite, and germanium to enhance the internal drying of the aqueous foamed soil or coating layer by using the radiant heat of the radiation materials. The uniformity of drying should be given. In addition, the use of ammonia water is used to maintain the pH between 7 and 8 after mixing to prevent shock during mixing by adjusting the pH between raw materials in aqueous foamed soil or blending.

In addition, the antifoaming agent used in the formulation uses a silicone-based and non-silicone-based thickener is Collulose Type-based and acrylic. The dispersant may be any system such as special anion, anion complex, and special nonionic complex.

In this way, after applying a certain amount of water-foamed tona mixed with the above-mentioned mixture to the wallpaper base material, materials such as wood flour, royal chicken powder, green powder, mugwort powder, hay powder, dry water grass powder, mineral charcoal powder, and thermally swelled vermiculite, etc. Separating (Used by classifying into 40 ~ 60 mesh, 60 ~ 80 mesh, 80 ~ 100 mesh, 100 ~ 120 mesh, etc.) Electrostatic charging method (aka: used as flocking method in fiber), that is, high voltage current (about 60,000W To generate static electricity so that natural materials can be adhered to the water-based foamed toner or upper part by the magnetic of static electricity (50 ~ 150g / m2 per 1㎡). Rotary screen, high pressure spraying method , After bonding by the scattering method, etc., apply 50-300 g / m2 (solid basis) of the above water-based foaming toner on the top again with a comma-coating gelling work (between 150-200 ℃)-printing process-top coating work After doing The bosing the job. At this time, the reason of recoating aqueous foam tona on top of natural materials is to form smoothness to enable printing work and to improve the embossability during embossing work.

In addition, the top coating is carried out to prevent the fouling resistance of the wallpaper and to protect the printing film. The top coating agent is an aqueous wax (using high temperature paraffin type, PE type, carnava wax, etc.) and aqueous meramine resin, in acrylic resin and urethane resin. Mix one or more of water-based epoxy water repellents and silicone water repellents, add 2-15 parts by weight, and apply 10-50 g / m2 as a solid content (based on solids). (At this time, natural materials can be used singly or in mixture of two kinds.)

In addition, the method shown in FIG. 2 is coated with 100 to 300 g / m 2 (based on solids) of the aqueous foamed toner on a wallpaper base material, and then the natural material is adhered to the upper portion thereof. It is increased by ~ 4,000 CPS in order of comma cotta work-drying-embossing work.

At this time, an aqueous blowing agent may be added to the top coating liquid (2-5% by weight) to impart embossing moldability.

In this case, when the flame retardancy is given to the wallpaper, the flame retardant treated wallpaper is generally used, and the flame retardant is an inorganic flame retardant of aluminum hydroxide.

At this time, the mixing ratio is 20 to 50% by weight, 5 to 10% by weight of water, 5 to 10% by weight of methanol and alcohol, 2 to 5% by weight of TiO ₂ , 2-7% by weight of aqueous foaming agent of butane and isopentane, 1 ~ 0.5% by weight of emulsifier, 5-10% by weight of talc and soft mica, 2 ~ 5% by weight of far-infrared radiation such as jade, flame retardant of aluminum hydroxide 20 ~ 30 A method for producing a flame retardant wallpaper having a flame retardant composition blended by weight%, ammonia water 0.01-0.1 weight% thickener 0.1-0.2 weight%, dispersant 0.1-0.5 weight%, antifoaming agent 0.1-0.5 weight% and the like.

The present invention is to provide an eco-friendly wallpaper that is applied by laminating the aqueous foaming tona and the above natural materials to the wallpaper paper by adding an aqueous foaming agent to the synthetic resin.
