gunstig kombinert virkning med hensyn til brannhemmende og gløde-hemmende effekt, idet virkningen av blandingen av de to stoffer forener de gunstige virkninger stoffene har hver for seg. Ved impregnering av materialer med alle de ovenfor omtalte midler, er materialet ført gjennom en vandig oppløsning av middelet eller midlene, og derefter tørket. favorable combined effect with regard to fire-retardant and flame-retardant effect, as the effect of the mixture of the two substances combines the beneficial effects of the substances individually. When impregnating materials with all of the agents mentioned above, the material is passed through an aqueous solution of the agent or agents, and then dried.
I de senere år er de såkalte høytrykkslaminater, dvs. impregnert kraftpapir sammenpresset med et dekkskikt på den ene eller begge overflater, blitt meget aktuelle for diverse formål, for eksempel innredning og møbler. In recent years, the so-called high-pressure laminates, i.e. impregnated kraft paper pressed together with a cover layer on one or both surfaces, have become very relevant for various purposes, for example interior design and furniture.
Disse laminater er relativt brennbare, og for spesielle anvendelser, for eksempel ved bruk i skip, er det stillet opp strenge krav til redusert brennbarhet og til liten røkutvikling for overflatematerialer, og som et resultat herav må slike høy-trykkslaminater tilføres brannhemmende midler. Hvis man for-søker å oppløse de vanligste uorganiske fosfater og eventuelt andre brannhemmende salter, for eksempel ammoniumbromid, i den alkoholiske oppløsning av fenolformaldehydharpiks, som anvendes som bindemiddel ved laminatfremstillingen, får man en utfelling av harpiks eller salter lenge før de nødvendige konsentrasjoner er nådd. Kraftpapiret impregneres derfor først med en vandig oppløsning av ett eller flere brannhemmende midler, vanligvis uorganiske salter, hvorefter papiret tørkes og så impregneres med en oppløsning av fenolformaldehydharpiks i vandig alkohol. These laminates are relatively flammable, and for special applications, for example when used in ships, there are strict requirements for reduced flammability and for little smoke development for surface materials, and as a result of this, such high-pressure laminates must be supplied with fire retardants. If you try to dissolve the most common inorganic phosphates and possibly other fire-retardant salts, for example ammonium bromide, in the alcoholic solution of phenol formaldehyde resin, which is used as a binder in the manufacture of laminates, you get a precipitation of resin or salts long before the required concentrations are reached . The kraft paper is therefore first impregnated with an aqueous solution of one or more fire retardants, usually inorganic salts, after which the paper is dried and then impregnated with a solution of phenol formaldehyde resin in aqueous alcohol.
Denne konvensjonelle to-trinns impregnering er komplisert og dyr, og ulempene ved de vanlige to-trinns prosesser for fremstilling av laminater har ført til mange forsøk på ett-trinns prosesser, og et slikt forsøk er beskrevet i britisk patent nr. 989.HO, hvor det for første gang anvendes et fosfat som er oppløselig i harpiksoppløsningen, nemlig et fosfat av et organisk amin. Denne prosess betyr utvilsomt et fremskritt, men impregnering med fosfat alene betinger store mengder, for eksempel ca. 20 vektprosent, for å tilfredsstille kravene til brann- og glødehemmende virkning, og bruken av så store mengder fosfat er kostbart og medfører dessuten sprøhet og tendens til delaminering i det ferdige laminat. This conventional two-stage impregnation is complicated and expensive, and the disadvantages of the usual two-stage processes for the manufacture of laminates have led to many attempts at one-stage processes, and such an attempt is described in British Patent No. 989.HO, where a phosphate which is soluble in the resin solution is used for the first time, namely a phosphate of an organic amine. This process undoubtedly means progress, but impregnation with phosphate alone requires large amounts, for example approx. 20% by weight, in order to satisfy the requirements for fire and glow-retarding effect, and the use of such large amounts of phosphate is expensive and also entails brittleness and a tendency for delamination in the finished laminate.
Fra U.S. patent nr. 2,415.113 er det kjent å anvende blandinger av ammoniumbromid og alkylsubstituerte diammonium-fosfater sammen med tiourinstoff i vandige oppløsninger for impregnering av tekstiler og andre cellulosematerialer for å gjøre disse brannsikre. I henhold til patentet anvendes tiourinstoff som primær brannhemmende bestanddel, og det nevnes intet om fremstilling av laminater eller de oppløselighets- From the U.S. patent no. 2,415,113, it is known to use mixtures of ammonium bromide and alkyl-substituted diammonium phosphates together with thiourea in aqueous solutions for impregnating textiles and other cellulosic materials to make them fireproof. According to the patent, thiourea is used as the primary fire-retardant component, and nothing is mentioned about the production of laminates or the solubility
og stabilitetsproblemer som man har ved laminatfremstilling og som søkes løst i henhold til foreliggende oppfinnelse. and stability problems that one has when manufacturing laminates and that are sought to be solved according to the present invention.
Vi har utført forsøk for å undersøke nærmere virkningen av ammoniumbromid og ammoniummetylfosfater (og delvis også andre ammoniumalkylfosfater) som brannhemmende bestanddeler i laminater. Forsøkene ble utført på følgende måte: I et kubisk prøvekammer ble 3 vegger og taket belagt med laminatet under prøvning. På den fjerde veggen var det montert en propanbrenner, som under forsøket brant med en fast mengde propan tilført pr. minutt, på samme vegg over brenneren var det et utløp som førte til en cyklon hvor partikler ble ut-skilt, og i røret som førte videre ut fra cyklonen, var det montert apparatur for måling av temperatur og lystransmisjon for undersøkelse av henholdsvis røktemperatur og røkutvikling. We have carried out experiments to investigate in more detail the effect of ammonium bromide and ammonium methyl phosphates (and partly also other ammonium alkyl phosphates) as fire-retardant components in laminates. The tests were carried out in the following way: In a cubic test chamber, 3 walls and the ceiling were coated with the laminate during testing. A propane burner was mounted on the fourth wall, which during the experiment burned with a fixed amount of propane supplied per minute, on the same wall above the burner there was an outlet that led to a cyclone where particles were separated, and in the pipe that led further out from the cyclone, apparatus was mounted for measuring temperature and light transmission for investigating smoke temperature and smoke development respectively .
Det ble funnet at ammoniumbromid hadde en bedre re-duserende virkning på røktemperaturen (som er et tegn på brannhemmende virkning) enn ammoniummetylfosfater, mens det motsatte var tilfelle for røkutviklingen. Bruk av ammoniumbromid alene vil derfor medføre at man må anvende uforholdsmessig store mengder for å få en tilfredsstillende lav røkutvikling, mens bruk av ammoniummetylfosfater (eller andre uorganiske eller organiske fosfater) alene -medfører at man må anvende uforholdsmessig store mengder for å få en tilfredsstillende brannhemmende virkning. Dette bekrefter også nødvendigheten av å anvende de store mengder fosfat som benyttes i henhold til ovennevnte britiske patent, idet det kun er selve fosfatgruppen i det anvendte brannhemmende fosfat som utøver noen brannhemmende virkning. Ammonium bromide was found to have a better reducing effect on smoke temperature (which is a sign of fire retardancy) than ammonium methyl phosphates, while the opposite was the case for smoke development. Using ammonium bromide alone will therefore mean that you have to use disproportionately large amounts to get a satisfactory low smoke level, while using ammonium methyl phosphates (or other inorganic or organic phosphates) alone - means that you have to use disproportionately large amounts to get a satisfactory fire retardant effect. This also confirms the necessity of using the large amounts of phosphate used in accordance with the above-mentioned British patent, as it is only the phosphate group itself in the fire-retardant phosphate used that exerts any fire-retardant effect.
Vi har nu overraskende funnet at det er mulig å ut-nytte den gunstige kombinerte effekt av disse to i og for seg kjente typer brannhemmende midler ved en ett-trinns prosess for fremstilling av laminater, hvilken gunstige kombinerte effekt består i at moderate mengder av begge de to typer brannhemmende midler i kombinasjon gir både en tilfredsstillende brannhemmende virkning og tilfredsstillende lav røkutvikling hos laminater fremstilt med harpiksoppløsninger inneholdende disse. Dette oppnåes ved at det som oppløsningsmiddel for de brannhemmende bestanddeler og harpiksen anvendes en alkohol-vann-blanding med et særlig avpasset forhold mellom alkohol og vann. I défté av-passede miljø er det ikke bare mulig å få inn de ønskede brannhemmende bestanddeler, men også den nødvendige mengde harpiks. Herved oppnåes ikke bare en utnyttelse av den fordelaktige kombinerte virkning av de to brannhemmende stoffer, men fenolformaldehydharpiks-oppløsningen med de brannhemmende bestanddeler har en lagringsstabilitet på flere måneder, hvilket langt overstiger det som hittil har vtcrt kjent for harpiksoppløsninger med brannhemmende tilsetninger» We have now surprisingly found that it is possible to exploit the favorable combined effect of these two types of fire retardants known per se in a one-step process for the production of laminates, which favorable combined effect consists in moderate amounts of both the two types of fire retardants in combination provide both a satisfactory fire retardant effect and a satisfactory low smoke development in laminates produced with resin solutions containing these. This is achieved by using an alcohol-water mixture with a particularly suitable ratio between alcohol and water as a solvent for the fire-retardant components and the resin. In a specially adapted environment, it is not only possible to get the desired fire-retardant components, but also the required amount of resin. This not only makes use of the advantageous combined effect of the two fire-retardant substances, but the phenol-formaldehyde resin solution with the fire-retardant components has a storage stability of several months, which far exceeds what has so far been known for resin solutions with fire-retardant additives."
I henhold til oppfinnelsen tilveiebringes således en brannhemmende, lagringsstabil fenolformaldehydharpiks-oppløsning som er særlig egnet for ett-trinns impregnering av kraftpapir for fremstilling av laminater, og harpiksoppløsningen karakteri-seres ved at den består av: According to the invention, a fire-retardant, storage-stable phenol-formaldehyde resin solution is thus provided which is particularly suitable for one-step impregnation of kraft paper for the production of laminates, and the resin solution is characterized by the fact that it consists of:
a) 35-50 vektprosent fenolformaldehydharpiks,a) 35-50 percent by weight phenol formaldehyde resin,
b) 30-62 vektprosent C1 ^ alkanol og vann i et vekt-forhold alkanol/vann på minst 0,60, fortrinnsvis mellom 0,85 og 2, og som synergistisk virkende, i og for seg kjente brannhemmende midler: c) 1-10 vektprosent C-j_4alkylfosfater og/eller ammoniumsalter derav, samt b) 30-62 percent by weight C1 ^ alkanol and water in a weight ratio alkanol/water of at least 0.60, preferably between 0.85 and 2, and as synergistically acting, fire retardants known in and of themselves: c) 1- 10 weight percent C-j_4 alkyl phosphates and/or ammonium salts thereof, as well as
d) 2-10 vektprosent ammoniumbromid.d) 2-10 percent by weight ammonium bromide.
Angitte vektprosent er regnet som tørrstoff på total Stated weight percentages are calculated as total dry matter
oppløsning av harpiks + brannhemmende stoffer.solution of resin + fire retardant substances.
Hvis man går høyere enn 50 vektprosent harpiks (tørr vekt) blir stabiliteten av harpiksoppløsningen for dårlig til langvarig oppbevaring, og går man lavere enn 35 vektprosent, får man en oppløsning som inneholder for lite harpiks til å gi tilfredsstillende laminater. If you go higher than 50% by weight resin (dry weight) the stability of the resin solution becomes too poor for long-term storage, and if you go lower than 35% by weight, you get a solution that contains too little resin to give satisfactory laminates.
EksempelExample
En oppløsning A ble fremstilt av 450 g av en fenolformaldehydharpiks-oppløsning og 150 g etanol. Penolformalde-hydharpiks-oppløsningen består av ca. 65 vektprosent alkali-katalysert fenolformaldehydharpiks med et molforhold formaldehyd/ fenol på 1,44, 17 vektprosent vann, 11 vektprosent etanol og 7 vektprosent fri formaldehyd og fenol, slik at 450 g derav inneholder ca. 295 g harpiks, 75 g vann, 50 g etanol og 30 g uomsatt formaldehyd og fenol. En oppløsning B ble fremstilt av 44 g ammoniumbromid, 41 g vandige ammoniummetylfosfater (bestående av ca. 65 vektprosent ammoniummetylfosfater og 35 vektprosent A solution A was prepared from 450 g of a phenol formaldehyde resin solution and 150 g of ethanol. The phenol formaldehyde-hyde resin solution consists of approx. 65 weight percent alkali-catalyzed phenol formaldehyde resin with a formaldehyde/phenol molar ratio of 1.44, 17 weight percent water, 11 weight percent ethanol and 7 weight percent free formaldehyde and phenol, so that 450 g of it contains approx. 295 g resin, 75 g water, 50 g ethanol and 30 g unreacted formaldehyde and phenol. A solution B was prepared from 44 g of ammonium bromide, 41 g of aqueous ammonium methyl phosphates (consisting of approximately 65% by weight ammonium methyl phosphates and 35% by weight
vann, dvs. henholdsvis ca. 27 og 14 g) og 60 g vann.water, i.e. respectively approx. 27 and 14 g) and 60 g of water.
De to blandinger A og B ble blandet omhyggelig og justert til en pH-verdi på ca. 5,2 ved hjelp av 25 #ig ammoniakk. Den resulterende blanding hadde således et innhold av ammonium-metylf osf ater på ca. 3,5 i» og av ammoniumbromid på ca. 6 vektprosent, og et etanol/vann-forhold på ca. 1,3. Blandingen var homogen og forble fullstendig klar i mer enn 4 måneder ved rom-temperatur. Laminater fremstilt ved hjelp av denne blanding til-fredsstilte med meget god margin de krav som stilles for flamme-spredning og røkutvikling av det Norske Veritas for overflatematerialer til bruk i korridorer og trappeoppganger. The two mixtures A and B were mixed carefully and adjusted to a pH value of approx. 5.2 using 25 #ig ammonia. The resulting mixture thus had an ammonium methyl phosphate content of approx. 3.5 i» and of ammonium bromide of approx. 6 percent by weight, and an ethanol/water ratio of approx. 1.3. The mixture was homogeneous and remained completely clear for more than 4 months at room temperature. Laminates produced using this mixture satisfied with a very good margin the requirements set for flame spread and smoke development by the Norske Veritas for surface materials for use in corridors and stairwells.
Istedenfor ammoniummetylfosfater kan man også anvende ammoniumetyl-, -propyl- og butylfosfater, men eftersom ammoniummetylfosfater inneholder mest av den aktive fosfatgruppe pr. vektenhet og dessuten gir de mest stabile oppløsninger, fore-trekkes disse. De rene Cj_^ alkylfosfater kan også anvendes, selv om stabiliteten av oppløsningene inneholdende disse ikke vil være så god som for oppløsninger inneholdende ammoniummetylfosfater. Instead of ammonium methyl phosphates, you can also use ammonium ethyl, -propyl and butyl phosphates, but since ammonium methyl phosphates contain most of the active phosphate group per unit of weight and also give the most stable solutions, these are preferred. The pure C 1-4 alkyl phosphates can also be used, although the stability of the solutions containing these will not be as good as for solutions containing ammonium methyl phosphates.
