Description
Denne oppfinnelse angår en med herdbare kunstharpikser impregnert og belagt bærematerialbane og en fremgangsmåte til fremstilling derav. Oppfinnelsen er angitt i kravene, og det vises til disse. This invention relates to a carrier material web impregnated and coated with hardenable synthetic resins and a method for its production. The invention is stated in the claims, and reference is made to these.
Det er kjent å impregnere bærebaner, særlig ensfarvede eller trykkdekorerte papirbaner, med varmeherdbar aminoplast eller fenoplast som er oppløst i vann eller vann-alkohol-blanding, og deretter tørre de erholdte filmer eller belegningsbaner. Disse er bestemt til å forbindes innbyrdes eller med trematerialer, så som sponplater, fiberplater og kryssfiner, ved hjelp av trykk og varme. It is known to impregnate carrier webs, in particular plain-coloured or print-decorated paper webs, with heat-curable aminoplast or phenoplast which is dissolved in water or a water-alcohol mixture, and then dry the resulting films or coating webs. These are intended to be connected to each other or to wooden materials, such as chipboard, fibreboard and plywood, using pressure and heat.
Den harpiksmengde som påføres på bærebanen ved impregneringen, er normalt tilstrekkelig til å bevirke en fast forbindelse med The amount of resin that is applied to the carrier during the impregnation is normally sufficient to effect a firm connection with
underlaget; i mange tilfeller blir det dessuten påført et strøk med lim eller en limhinne mellom underlaget og den herdbare kunstharpiks-hinne i tillegg til harpiksimpregneringen. the substrate; in many cases, a coat of glue or an adhesive membrane is also applied between the substrate and the hardenable synthetic resin membrane in addition to the resin impregnation.
Det er også kjent at det er mulig å utføre impregneringen It is also known that it is possible to carry out the impregnation
med aminoplast eller fenoplast i to eller flere på hinannen følgende trinn, hvor de forskjellige impregneringstrinn foretas med harpikser som med hensyn til sammensetning, viskositet og reaktivitet er innbyrdes forskjellige. with aminoplast or phenoplast in two or more consecutive steps, where the various impregnation steps are carried out with resins which are mutually different in terms of composition, viscosity and reactivity.
Ved høyverdige belegningsmaterialer, spesielt ved belagte trematerialer, er det videre vanlig at belegget bygges opp av flere lag, hvorunder aminoplast- eller fenoplast-impregnerte papirlag på-føres etter hverandre eller samtidig. Ved denne fremgangsmåte skiller man mellom papir som er "underlay", dekorpapir og "overlay". In the case of high-quality coating materials, especially coated wood materials, it is also common for the coating to be built up from several layers, under which aminoplast or phenoplast-impregnated paper layers are applied one after the other or simultaneously. With this method, a distinction is made between paper that is "underlay", decorative paper and "overlay".
Belegningen av trematerialer med på en bærer påførte kunst-harpikshinner er imidlertid ikke begrenset til anvendelsen av aminoplast henholdsvis fenoplast. Man har anvendt eller foreslått andre polykondenserbare eller polymeriserbare harpikser; spesielt er det allerede kjent å impregnere papir med polymeriserbare forbindelser, for eksempel diallylftalat(-prepolymerer) eller med fornettbare polymerer av typen umettede polyesterharpikser. Også disse belegningsmaterialer kan forbindes med egnede trematerialer ved hjelp av trykk og varme. En oversikt over de hittil kjente muligheter er eksempelvis å finne i "Moderne Beschichtungsverfahren fur Holzwerk-stoffe" av W. Enzensberger, publisert i "Holz als Roh- und Werkstoff", 27. årgang, hefte 12. However, the coating of wood materials with artificial resin membranes applied to a carrier is not limited to the use of aminoplast or phenoplast. Other polycondensable or polymerizable resins have been used or proposed; in particular, it is already known to impregnate paper with polymerisable compounds, for example diallyl phthalate (prepolymers) or with crosslinkable polymers of the unsaturated polyester resin type. These coating materials can also be connected to suitable wood materials by means of pressure and heat. An overview of the hitherto known possibilities can be found, for example, in "Moderne Beschichtungsverfahren fur Holzwerk-stoffe" by W. Enzensberger, published in "Holz als Roh- und Werkstoff", volume 27, issue 12.
De kjente muligheter til overflateforedling av trematerialer er særdeles mangesidige. De kjente harpikspreparater og teknikken ved deres forarbeidelse er imidlertid i mange tilfeller ikke til-fredsstillende når de forhåndenværende maskinelle muligheter til forarbeidelsen skal utnyttes optimalt. De maskinelle forarbeidel-sesmuligheter innsnevres i mange tilfeller også ved selve tremate-rialets og hjelpestoffenes egne begrensninger. The known possibilities for surface treatment of wooden materials are extremely versatile. However, the known resin preparations and the technique for their processing are not satisfactory in many cases when the existing mechanical possibilities for the processing are to be utilized optimally. The mechanical processing possibilities are in many cases also narrowed down by the wood material itself and the auxiliaries' own limitations.
Eksempelvis kan man ikke ved laminering av trematerialer og filmer fremstilt på basis av aminoplast eller fenoplast oppnå overflater som oppviser lakkerte flaters høye glans. Av denne grunn blir belagte materialer, dvs. materialer som ved bruk av trykk og varme er forsynt med et beskyttelsessjikt, ofte forsynt med et egnet lakksjikt i et separat arbeidstrinn og eventuelt dessuten polert for oppnåelse av den ønskede høye glans. For example, by laminating wooden materials and films made on the basis of aminoplast or phenoplast, you cannot achieve surfaces that exhibit the high gloss of lacquered surfaces. For this reason, coated materials, i.e. materials that are provided with a protective layer through the use of pressure and heat, are often provided with a suitable varnish layer in a separate work step and possibly also polished to achieve the desired high gloss.
Spesielt sterkt innsnevret er mulighetene for oppnåelse av overflateglans når belegningen foretas med aminoplastisk eller fenoplastisk bundne bærematerialer og man herunder anvender den økonomisk fordelaktige såkalte korttaktmetode, hvor man gir avkall på en tilbakekjøling av pressplatene. The possibilities for achieving a surface gloss are particularly narrowed when the coating is carried out with aminoplastic or phenoplastic bonded carrier materials and one uses the economically advantageous so-called short-stroke method, where one foregoes a cooling of the press plates.
Filmer av umettede polyesterharpikser eller diallylfta-latpolymerer eller blandinger derav har lakkaktig glans også uten tilbakekjøling; belegning med slike harpiksfilmer, hvor det må bru-kes forholdsvis store materialmengder sammenlignet med eksempelvis lakkering, medfører imidlertid høye kostnader på grunn av utgifte-ne til harpiks, og den uunngåelige bruk av organiske løsningsmid-ler er en teknisk ulempe ved belegningsmetoder hvor det anvendes umettede polyesterharpikser eller diallylftalat. Films of unsaturated polyester resins or diallyl phthalate polymers or mixtures thereof have a lacquer-like gloss even without recooling; coating with such resin films, where relatively large amounts of material must be used compared to e.g. painting, however, entails high costs due to the expenses for resin, and the inevitable use of organic solvents is a technical disadvantage of coating methods where it is used unsaturated polyester resins or diallyl phthalate.
Dessuten hefter polyesterharpikser ikke godt til bærematerialer av papir eller lignende, hvorfor det i BRD-off.skrift 2 136 378 i den senere tid er blitt foreslått å fremstille dekora-sjonsplater ved hjelp av slike harpiksbehandlede papirmaterialer hvis fibre - eventuelt allerede i papirfremstillingstrinnet - er forbehandlet med eksempelvis melamin- eller urinstoffharpikser og deretter impregnert med en polyesterharpiks eller en diallylftalat-harpiks. I motsetning til den foreliggende oppfinnelse går forsla-get ifølge ovennevnte off.skrift, kort uttrykt, ut på å skaffe et polyesterharpiks-belegg med forbedrede hefteegenskaper. Dette forslag er ikke sammenlignbart med den foreliggende oppfinnelse, Furthermore, polyester resins do not adhere well to carrier materials made of paper or the like, which is why in BRD-off.skrift 2 136 378 it has recently been proposed to produce decorative panels using such resin-treated paper materials whose fibers - possibly already in the paper production stage - are pre-treated with, for example, melamine or urea resins and then impregnated with a polyester resin or a diallyl phthalate resin. In contrast to the present invention, the proposal according to the above-mentioned publication, briefly stated, aims to provide a polyester resin coating with improved adhesion properties. This proposal is not comparable to the present invention,
da det her hovedsakelig dreier seg om et aminoplastharpiks-belegg hvis overflatestruktur forbedres. as here it is mainly an aminoplast resin coating whose surface structure is improved.
Den foreliggende oppfinnelse angår et bæremateriale som er impregnert og belagt med herdbare kunstharpikser, for overflateforedling av trematerialer og bestående av en bærematerialbane som a) på i og for seg kjent måte er impregnert med en herdbar aminoplastisk eller fenoplastisk impregneringsharpiks og b) på den ene side er forsynt med et belegg av en umettet herdbar polyesterharpiks, karakterisert ved at belegget av umettet herdbar polyesterharpiks består av en ved fortykning gjennom oppvarmning størknet blanding av 20-98 % av en ikke krystalliserbar og 2-80 % av en krystalliserbar polyester som ved romtemperatur er tungt oppløse-lig i de vanlige monomerer som virker fornettende og som tjener som løsningsmiddel, samt eventuelt de vanlige fornetningsdyktige oppløsningsmidler for umettede polyesterharpikser. Fremgangsmåten ifølge oppfinnelsen til fremstilling av bærematerialbanen følger stort sett beskrivelsen av oppbygningen av banematerialet, se krav 2. The present invention relates to a carrier material which is impregnated and coated with hardenable synthetic resins, for the surface treatment of wooden materials and consisting of a carrier material web which a) is impregnated in a manner known per se with a hardenable aminoplastic or phenoplastic impregnation resin and b) on one side is provided with a coating of an unsaturated curable polyester resin, characterized in that the coating of unsaturated curable polyester resin consists of a solidified mixture of 20-98% of a non-crystallisable and 2-80% of a crystallisable polyester which at room temperature is solidified by thickening through heating poorly soluble in the usual monomers which have a cross-linking effect and which serve as solvents, as well as possibly the usual cross-linking-capable solvents for unsaturated polyester resins. The method according to the invention for producing the carrier material web largely follows the description of the structure of the web material, see claim 2.
Det harpikspreparat som anvendes som belegg, betegnes i det følgende for enkelhets skyld "polyesterharpiksblanding". The resin preparation used as a coating is referred to in the following for simplicity as "polyester resin mixture".
Av nedenstående vil det sees hvordan oppfinnelsen skiller seg fra det som er kjent.Det ér kjent at polyestere som er oppbygget av utstrukket-symmetrisk oppbyggede syre- eller alkohol-mole-kyler, og altså inneholder eksempelvis fumarsyre-, tereftalsyre-, adipinsyre- eller sebacinsyre-enheter på den ene side og uforgre-ne'de eller symmetrisk' forgrenede dioliske grupper på den annen side, som i etylenglykol, butandioler (1,4), (i alminnelighet a,w-polymetylenglykoler) eller eksempelvis i neopentylglykol og i hydroksypivalinsyre-neopentylglykolester, er krystalliserbare og foreligger i fast form i krystallinsk tilstand. From the following it will be seen how the invention differs from what is known. It is known that polyesters which are made up of extended symmetrically structured acid or alcohol molecule chains, and therefore contain, for example, fumaric acid, terephthalic acid, adipic acid or sebacic acid units on the one hand and unbranched or symmetrically branched diol groups on the other, such as in ethylene glycol, butanediols (1,4), (generally a,w-polymethylene glycols) or, for example, in neopentyl glycol and in hydroxypivalic acid-neopentyl glycol esters, are crystallizable and are available in solid form in a crystalline state.
Disse krystallinske eller krystalliserbare polyestere er av kjente årsaker vanligvis tungt løselige, særlig i løsnings-midler (monomerer) som kan fornettes,, så som styren, diallylftalat eller metylmetakrylat, som vanligvis danner oppløsningsgrunn-laget for'flytende, umettede polyesterharpikser. Videre er de uoppløselige i de ved romtemperatur flytende, ikke-krystalliserbare polyestere og selvsagt også i blandinger derav med monomerer. These crystalline or crystallizable polyesters are, for known reasons, usually poorly soluble, especially in solvents (monomers) which can be cross-linked, such as styrene, diallyl phthalate or methyl methacrylate, which usually form the solvent base for liquid, unsaturated polyester resins. Furthermore, they are insoluble in the non-crystallisable polyesters which are liquid at room temperature and of course also in mixtures thereof with monomers.
Krystallinske polyestere er eksempelvis beskrevet i US-patent nr. 3 396 128, 3 455 870 og 3 510 457, og det henvises herved til disse. I det sistnevnte patentskrift angis under .krystallinske polyestere også såkalte "partielle krystallinske polyestere", og også disse kommer i betraktning innenfor den foreliggende oppfinnelses ramme. Crystalline polyesters are, for example, described in US Patent Nos. 3,396,128, 3,455,870 and 3,510,457, and reference is hereby made to these. In the latter patent, crystalline polyesters are also referred to as "partially crystalline polyesters", and these too come into consideration within the framework of the present invention.
Polyestere som mer eller mindre statistisk er oppbygget av Polyesters that are more or less statistically made up of
de vanlige, særlig da av de billige dikarboksylsyrer, for eksempel o-ftalsyre og tilsvarende dioler, ér derimot vanligvis lett løse- the common ones, especially those of the cheap dicarboxylic acids, for example phthalic acid and corresponding diols, on the other hand, are usually easily soluble
lige eller flytende og stivner eventuelt i amorf (glassaktig) tilstand. Disse amorfe polyestere danner den langt overveiende mengde av de vanlige umettede polyesterharpikser som anvendes sombelegnings-eller impregneringsmiddel, og utgjør også det vesentlige råmateriale for de såkalte glassfiberforsterkede kunstharpikser (GFK). straight or liquid and possibly solidifies in an amorphous (glassy) state. These amorphous polyesters form the vast majority of the usual unsaturated polyester resins used as coating or impregnating agent, and also form the essential raw material for the so-called glass fiber reinforced synthetic resins (GRP).
I henhold til oppfinnelsen oppnås, på basis av polyesterharpiks-preparater og i forbedret form, belegg for aminoplast- eller fenoplast-impregnerte (kjerneimpregnerte) papirmaterialer ved anvendelse av én blanding av forskjellige, dvs. minst én krystalliserbar og én ikke-krystalliserbar polyester, eventuelt i tilsvarende suspensjon eller oppløsning. According to the invention, on the basis of polyester resin preparations and in an improved form, coatings for aminoplast or phenoplast-impregnated (core-impregnated) paper materials are obtained by using one mixture of different, i.e. at least one crystallizable and one non-crystallizable polyester, optionally in corresponding suspension or solution.
Anskuelig sagt danner den krystallinske komponent i poly-esterharpiksblandingen her et fortykningsmiddel av en spesiell art: Under impregneringsprosessen danner den krystallinske fase en relativt lettflytende suspensjon; herunder anvendes vanligvis romtemperatur. Deretter følger en fortykningsprosess, som ut- Apparently, the crystalline component in the polyester resin mixture here forms a thickening agent of a special kind: During the impregnation process, the crystalline phase forms a relatively easy-flowing suspension; below, room temperature is usually used. Then follows a thickening process, which
føres ved 50-120°C, og som følges av en midlertidig smeltning av den krystallinske fase; etter avkjølingen danner den på ny utskilte krystallinske masse et nettverk som har en meget forsterkende virkning. is conducted at 50-120°C, and which is followed by a temporary melting of the crystalline phase; after cooling, it forms a network on the newly separated crystalline mass which has a very reinforcing effect.
Polyesterharpiksblandingene inneholder vanligvis dessuten The polyester resin compositions usually also contain
ca. 0,5-5% av et uorganisk fortykningsmiddel, gjerne på basis av et jordalkalihydroksyd eller -oksyd, som griper inn i fortykningsprosessen. Det ble overraskende observert at den i og for seg kjente fortykningsprosess ved ikke-krystalliserbare polyestere, som man antar består i en salt- eller kompleksdannelse mellom Mg<++->ioner og karboksylgrupper, overraskende akselereres ved tilsetning av selv ganske små mengder krystalliserbar polyester. En mengde på 5-40% about. 0.5-5% of an inorganic thickening agent, preferably based on an alkaline earth hydroxide or oxide, which intervenes in the thickening process. It was surprisingly observed that the per se known thickening process of non-crystallizable polyesters, which is assumed to consist of a salt or complex formation between Mg<++->ions and carboxyl groups, is surprisingly accelerated by the addition of even quite small amounts of crystallizable polyester .

Harpiksene kan også inneholde mindre mengder aven- og flerverdige karboksylsyrer eller alkoholer, så som benzoesyre, olje-syre, trimelitsyre, pyromellitsyre, etylheksanol, trimetylolpropan, glycerol, pentaerytritol og andre. De ikke-krystalliserbare polyestere er overveiende blandingskondensater av de ovenfor nevnte monomerer. ;Syrer og alkoholer er som kjent normalt tilstede i ekvivalente mengder, dog kan det foreligge opp til 20% avvikelse fra ek-vivalens nedover eller oppover. De umettede polyestere har i alminnelighet syre- henholdsvis hydroksyl-tall mellom 20 og 70. ;Ved mengden av dobbeltbindinger i den umettede dikarbok-sylsyre i forhold til den totale syremengde og ved valg av alkohol er det mulig å variere konsentrasjonen av kopolymeriserbare dobbeltbindinger i polyesteren innenfor vide grenser. Da omsetningen av disse dobbeltbindinger delvis bestemmer fornettingstettheten, og da man i alminnelighet tilstreber en høy fornettingstetthet, bør polyesteren oppvise en høy grad av umettethet. Særlig fordelaktig er slike ikke krystalliserbare polyestere som ved romtemperatur og i fravær av løsningsmidler eller monomerer er faste og klebefrie, og som ved passende valg av komponentene, henholdsvis forpolymeri-satenes molekylvekt kan fremstilles uten videre på i og for seg kjent måte. ;Mens de ikke-krystallinske polyester-forpolymerer, som er faste ved romtemperatur, smelter ved en temperatur vanligvis under 70°c og da går fra en glassaktig tilstand til en flytende tilstand, smelter eller mykner de krystallinske polyestere vanligvis først ved en temperatur over 70°C. Et spesielt skilledyktig kriterium er imidlertid oppløseligheten, for eksempel i styren, ved 20-25°c: Mens de krystallinske eller delvis krystallinske polyestere har en oppløselighet på under 10%, slik at de i en mengde på over 10% alltid danner en suspensjon med styren, er de ikke-krystallinske polyestere alltid mer enn 10% oppløselige og vanligvis blandbare med styren i alle forhold. Selv oppløsninger som inneholder mer enn 70% polyester i styren, er flytende ved 20-25°C. For andre monomere løsningsmidler gjelder naturligvis i prinsippet det samme. ;Spesielt godt egnede polyesterblandinger består av 10-80%, særlig 10-50%, av en etylenisk umettet polymeriserbar monomer og 20-90%, særlig 50-90%, polyester som består av en blanding av 20- ;98%, særlig 60-96%, av ikke krystalliserbare polyestere og 2-80%, særlig 4-40%, av krystalliserbare polyestere. ;De ufornettbare forpolymerisaters klebefrihet og fasthet ved romtemperatur kan oppnås ved omsetning med metallsalter, særlig - ;som nevnt ovenfor - metalloksyder eller metallhydroksyder, hvorved det dannes saltaktige bindinger mellom nabomolekyler, slik at det øyeblikkelig oppstår en tilsynelatende molekylvekf-forhøyelse. De ofte harpiksaktige eller klebrige produkter blir på denne måte hårde og klebefrie. ;Fornettingsmidler, eller monomerer, som i passende ;mengder delvis også er egnet som løsningsmidler, er slike etylenisk umettede kopolymeriserbare forbindelser som inneholder en eller flere dobbeltbindinger i molekylet, som for eksempel styren, klorstyren, metylmetakrylat, butylakrylat, diallylftalat, divinylbenzen; ennvidere for-polymerer av de polyfunksjonelle fornettingsmidler med frie dobbeltbindinger, som for eksempel for-polymerer av diallylftalat, ;som også i og for seg har filmdannende egenskaper eller kan herdes med kjente midler. ;Som katalysatorer kan det anvendes slike forbindelser som under pressbetingelsene, dvs. over 100°C, leverer radikaler, for eksempel azoforbindelser, peroksyder og andre. ;Som tilsetninger til såvel impregneringsharpiksene som po-lyesteroverflateharpiksene som påføres ifølge oppfinnelsen, kan det eksempelvis anvendes uorganiske fyllstoffer, så som kritt, dolomitt, kalk, uorganiske eller organiske pigmenter så som titandioksyd, kiselsyregeler, organiske, svakt fornettede, pulverformige materialer som er istand til å svelle sterkt, som for eksempel partielt fornettede umettede polyesterharpikser, ennvidere forløps-hjelpemidler, tiksotropi-hjelpemidler og andre. ;Det er en spesiell fordel i henhold til oppfinnelsen ;at belegget eller filmen allerede med presstider på ca. 30 sekunder ved anvendelse av en temperatur på ca. 160°c kan påpresses på sponplater og fiberplater uten at pressplatene må kjøles etter pressingen. Ved denne såkalte korttaktmetode oppnås i henhold til oppfin- ;nelseri overflater med høy glans; med konvensjonelle amino- ;plastiske bindemidler har dette hittil ikke vært mulig. ;Det er herunder fordelaktig at det presstrykk som skal 'anvendes"4, er forholdsvis lavt, f .eks. innen området mellom 7,5 dg 10 kp/cm . Dette lave trykk skåner platemateria-let,"spesielt hår det gjelder sponplater, med lav tetthet, pg muliggjør også påføring av særlig tynne overflatebeskyttelses-sjikt, daudet underliggende tremateriales , struktur ikke så lett fremtrer på overflaten ("gjennomtelegraf erer") ved/.dette lave 'presstrykk.

Vis-kositeten av aminoplast- henholdsvis fenoplast-impregneringshar-piksløsningene, som i regelen har et faststoffinnhold mellom 45 og 55%, ligger vanligvis mellom 30 og 65 cp. En beskrivelse av egnede aminoplastiske impregneringsharpikser finnes eksempelvis i boken av CP. Vale, Aminoplastics, London 1950. ;Impregneringsharpiksløsningenes reaktivitet kan innstilles ;på den nødvendige eller ønskede presshastighet ved tilsetning av herdemidler. Vanligvis inneholder harpiksløsningen også fuktemidler til å forbedre gjennomtrengningen av papiret, og dessuten for eksempel skumhindrende midler. ;Det etter impregneringen av bærematerialbanen innskutte tørketrinn er i og for seg kjent. Da man nå vanligvis anvender kon-tinuerlige belegningsmetoder, utføres også tørketrinnet i kontinu-erlig arbeidende anlegg, for eksempel en svevetørke. ;I henhold til oppfinnelsen blir den forimpregnerte og tør-rede bærematerialbane nå påført den nevnte blanding av ikke krystalliserbar og krystalliserbar, tungtløselig polyester. Pre-parater av denne art inneholder vanligvis foruten bindemiddelet også fornetningsmidler, katalysatorer og andre tilsetninger. Påføringen av preparatene kan for eksempel skje ved støping, valsing, sprøyting, påstryking eller lignende. Vedkommende arbeidsteknikk vil være kjent for fagfolk og behøver derfor ikke gis noen uttømmende omtale her. De anvendte mengder kan variere etter omstendighetene; det dreier seg imidlertid vanligvis om mengder av polyesterharpiks som er relativt små i forhold til den aminoplastiske eller fenoplastiske impregneringsharpiks, og som bare i sjeldne tilfeller når den samme størrelsesorden. Mengden av polyesterblandingen kan med fordel ut-gjøre 20-l0O% av impregneringsharpiksens vekt. Denne på sin side anvendes i en mengde på eksempelvis 50-180% av papirvekten. ;Ved tilsetning av metalloksyder eller metallhydroksydér, som for eksempel magnesiumoksyd, kalsiumoksyd og ekvivalente hydrok-syder kan polyesterpreparatene om nødvendig fortykkes, eventuelt inn-til det dannes nesten klebefrie geler, som uten videre forandring kan lagres i lengre tid, og som kan fornettes først ved oppvarming. Ved valg av egnede midler kan imidlertid også en for-fornetning tilveie-bringes ved hjelp av tilsetninger som utløser ionisk polymerisasjon. ;Det er ikke ubetinget nødvendig at polyesterharpiksen påfø-res i et løsningsmiddel eller en løsningsmiddelblanding. For fremstilling av klebefrie, senere godt herdbare dekksjikt er det imidlertid ofte fordelaktig å tilsette til dan reaktive monomer, som normalt utgjør hovedmengden av løsningsmiddelet, også et lettflyktig løsningsmiddel og fjerne dette ved en varmebehandling etter påførin-gen. ;Fremstilling av forskjellige ikke-krystalliserbare polyesterharpiks-preparater (deler betyr vektdeler) a) 400 deler av en 60%'s acetonisk oppløsning av en umettet polyester med et mykningspunkt (etter KSN) på 75-80°C, som var fremstilt av maleinsyre, tereftalsyredimetylester og propylenglykol-1,2 i molforholdet 1:1:2 (syretall ca. 20), blandes med 103 deler av en diallylftalat-prepolymer og homogeniseres ved 24 timers omrøring ved romtemperatur. ;Til blandingen tilsettes 6% tert.-butylperoktoat. Etter henstand utskilles et bunnfall, som dog lett lar seg røre opp. Til harpiksblandingen tilsetter man under omrøring 2,5% av en pulverformig, partielt fornettet polyesterharpiks. ;b) 80 deler av en 50%'s oppløsning av diallylftalat-prepolymer i monomert diallylftalat og 400 deler av en 60%<*>s acetonisk In addition, it includes the use of fur materials for road materials, such as carrier materials, such as these often used in the production of layer materials. ,<v; W* ;In accordance with the objective of the invention; after- ;■ .;.v i-.v:; v ■ > i - i ->v JTT... «•---•' •. ■'" ; action of the aminoplast,-_ or phenoplast-impregnated-support material^.- .: clay with an artificial resin. on the basis. of, a certain: unsaturated-polyester: ' ^ however id^ generally limited : ti 1 such r t« rematerials which will form the outermost or uppermost layer of the final product such as non-crystalline or non-crystallizable polyester resin different . systems are suitable. ; ;>>j •aul.'." ^ A^ ui! j;c.t-.--y...S :■■ ;, Thus, you can use polymerized polyestersMmedietV' • ; • < solid cross-linking agent. , ;further.,,you can.,you can use unsaturated polyesters .:' :: dissolved in a ..liquid f cross-linking agent,. r for example, styrene; f.ogosome' ;contains a thickening agent, such as magnesium oxide. ;As unsaturated, non-crystallizable polyesters, polyesters based on raaleic acid can be used, for example, fumaric acid, tetrahydrophthalic acid as unsaturated dicarboxylic acids; phthalic acids, adipic acid, succinic acid, hexachloroendomethylenetetrahydrophthalic acid and others as saturated dicarboxylic acids; ethylene glycol, propylene glycol, butanediols, neopentyl glycol, hydroxypivalic acid-neopentyl glycol ester, hexanediol-1,6, hydrogenated bisphenol A, dioxalkylated bisphenol A and others such as diols. The resins may also contain smaller amounts of mono- and polyhydric carboxylic acids or alcohols, such as benzoic acid, oleic acid, trimellitic acid, pyromellitic acid, ethylhexanol, trimethylolpropane, glycerol, pentaerythritol and second. The non-crystallizable polyesters are predominantly mixture condensates of the above-mentioned monomers. As is well known, acids and alcohols are normally present in equivalent amounts, however there can be up to 20% deviation from equivalency downwards or upwards. The unsaturated polyesters generally have an acid or hydroxyl number between 20 and 70. By the amount of double bonds in the unsaturated dicarboxylic acid in relation to the total amount of acid and by choosing the alcohol, it is possible to vary the concentration of copolymerisable double bonds in the polyester within wide limits. As the turnover of these double bonds partly determines the cross-linking density, and as one generally strives for a high cross-linking density, the polyester should exhibit a high degree of unsaturation. Particularly advantageous are such non-crystallisable polyesters which at room temperature and in the absence of solvents or monomers are solid and non-sticky, and which, by appropriate selection of the components, respectively the molecular weight of the prepolymers, can be produced without further ado in a manner known per se. ;While the non-crystalline polyester prepolymers, which are solid at room temperature, melt at a temperature usually below 70°C and then go from a glassy state to a liquid state, the crystalline polyesters usually melt or soften only at a temperature above 70 °C. However, a particularly distinguishing criterion is the solubility, for example in styrene, at 20-25°c: While the crystalline or partially crystalline polyesters have a solubility of less than 10%, so that in an amount of more than 10% they always form a suspension with styrene, the non-crystalline polyesters are always more than 10% soluble and usually miscible with styrene in all proportions. Even solutions containing more than 70% polyester in styrene are liquid at 20-25°C. Naturally, the same applies in principle to other monomeric solvents. Particularly suitable polyester mixtures consist of 10-80%, especially 10-50%, of an ethylenically unsaturated polymerizable monomer and 20-90%, especially 50-90%, polyester which consists of a mixture of 20-;98%, especially 60-96%, of non-crystallizable polyesters and 2-80%, especially 4-40%, of crystallizable polyesters. The non-crosslinkable prepolymers' non-stickiness and firmness at room temperature can be achieved by reaction with metal salts, in particular - as mentioned above - metal oxides or metal hydroxides, whereby salt-like bonds are formed between neighboring molecules, so that an apparent increase in molecular weight immediately occurs. The often resinous or sticky products become hard and non-sticky in this way. Cross-linking agents, or monomers, which in appropriate amounts are partly also suitable as solvents, are such ethylenically unsaturated copolymerisable compounds that contain one or more double bonds in the molecule, such as styrene, chlorostyrene, methyl methacrylate, butyl acrylate, diallyl phthalate, divinylbenzene; further pre-polymers of the polyfunctional cross-linking agents with free double bonds, such as for example pre-polymers of diallyl phthalate, which also in and of themselves have film-forming properties or can be cured with known means. As catalysts, such compounds can be used which, under the pressure conditions, i.e. above 100°C, deliver radicals, for example azo compounds, peroxides and others. As additives to both the impregnation resins and the polyester surface resins that are applied according to the invention, inorganic fillers can be used, for example, such as chalk, dolomite, lime, inorganic or organic pigments such as titanium dioxide, silica gels, organic, weakly cross-linked, powdery materials that are to swell strongly, such as partially cross-linked unsaturated polyester resins, further flow aids, thixotropy aids and others. It is a particular advantage according to the invention that the coating or film already with pressing times of approx. 30 seconds using a temperature of approx. 160°c can be pressed onto chipboard and fiberboard without the pressing plates having to be cooled after pressing. With this so-called short stroke method, according to the invention, surfaces with a high gloss are obtained; with conventional amino-plastic binders this has not been possible until now. It is also advantageous that the pressure to be used4 is relatively low, e.g. within the range between 7.5 dg 10 kp/cm. This low pressure protects the sheet material, especially when it comes to chipboard, with low density, pg also enables the application of particularly thin surface protection layers, the structure of the underlying wood material does not appear so easily on the surface ("through telegraphs") at this low pressure. In this way, it is possible to.fr.emsti-lle no. layer-coated chipboards in a particularly cheap way. in the case, respectively, of plastic binders on the underlayer of wood, acts against the polyester resin layer, which forms the outermost surface of the product to be produced. : les, which héf témediates and prevents gout.... Rich-:-; lies in the possibility of a particularly fast processing and in the "good joining effect. -,. ;Furthermore, a surface is obtained which, due to its elasticity, and its fluidity during pressing, is closed and quite free of cracks, with the so-called graphite test, a very good result is obtained. The pre-impregnation of the carrier web is carried out in a known manner. The viscosity of the aminoplast and phenoplast impregnation resin solutions, as in has a solids content between 45 and 55%, is usually between 30 and 65 cp. A description of suitable aminoplastic impregnation resins can be found, for example, in the book by CP. Vale, Aminoplastics, London 1950. The reactivity of the impregnating resin solutions can be adjusted to the required or desired press speed by adding curing agents. Usually, the resin solution also contains wetting agents to improve the penetration of the paper, and additionally, for example, anti-foaming agents. The drying step inserted after the impregnation of the carrier material web is known in and of itself. As continuous coating methods are now usually used, the drying step is also carried out in a continuously operating plant, for example a suspended dryer. According to the invention, the pre-impregnated and dried carrier material web is now applied to the aforementioned mixture of non-crystallisable and crystallisable, sparingly soluble polyester. Preparations of this kind usually contain, in addition to the binder, cross-linking agents, catalysts and other additives. The preparations can be applied, for example, by casting, rolling, spraying, brushing or the like. The relevant work technique will be known to professionals and therefore need not be given an exhaustive description here. The quantities used may vary according to the circumstances; however, it usually involves amounts of polyester resin that are relatively small in relation to the aminoplastic or phenoplastic impregnation resin, and which only in rare cases reach the same order of magnitude. The amount of the polyester mixture can advantageously be 20-100% of the weight of the impregnation resin. This, in turn, is used in an amount of, for example, 50-180% of the paper weight. By adding metal oxides or metal hydroxides, such as magnesium oxide, calcium oxide and equivalent hydroxides, the polyester preparations can be thickened if necessary, possibly until almost adhesive-free gels are formed, which can be stored for a longer time without further change, and which can be cross-linked first during heating. By choosing suitable agents, however, a pre-crosslinking can also be provided by means of additives which trigger ionic polymerisation. It is not absolutely necessary that the polyester resin is applied in a solvent or a solvent mixture. However, for the production of adhesive-free, subsequently well-hardenable cover layers, it is often advantageous to add to the then reactive monomer, which normally makes up the bulk of the solvent, also a volatile solvent and remove this by a heat treatment after application. ;Preparation of various non-crystallizable polyester resin preparations (parts means parts by weight) a) 400 parts of a 60% acetone solution of an unsaturated polyester with a softening point (according to KSN) of 75-80°C, which was prepared from maleic acid , terephthalic acid dimethyl ester and propylene glycol-1,2 in the molar ratio 1:1:2 (acid number approx. 20), are mixed with 103 parts of a diallyl phthalate prepolymer and homogenized by stirring for 24 hours at room temperature. 6% tert-butyl peroctoate is added to the mixture.

Harpiskbelegget ut-o A lightly filled decorative paper with print, which was produced from a-cellulose and had a basis weight of 80 g/m 2 , is impregnated with an aqueous solution of a mixed condensate of urea, melamine and formaldehyde (resin absorption is approx. 90% of the paper weight). The residual moisture content, determined by a 5-minute post-drying at 160°C, is 5.6%. In another work step, the unsaturated polyester resin mixture described above is applied to the upper side.

Det impregnerte og belagte papir dekkes med en termoplastisk polyesterfolie "Hostaphan" fra Farbwerke Hoechst AG) og behandles ved 80°C i en svevetørke i 3 minutter, hvoretter den hurtig bringes på romtemperatur. Dekkfolien kan uten beskadigelse trekkes av, og laminatet legges uten mellomsjikt på en 19 mm tykk sponplate med polyestersjiktet opp. The impregnated and coated paper is covered with a thermoplastic polyester film "Hostaphan" from Farbwerke Hoechst AG) and treated at 80°C in a hover dryer for 3 minutes, after which it is quickly brought to room temperature. The cover foil can be removed without damage, and the laminate is laid without an intermediate layer on a 19 mm thick chipboard with the polyester layer facing up.
Deretter presses i en såkalt korttaktpresse i 120 sekunder ved 160°C under et trykk på 4 kp/cm<2>. Den således belagte sponplate tas ut av den varme presse uten tilbakekjøling. Allerede ved dette lave trykk oppnås overflater som oppviser en høy glansgrad, og som utmerker seg ved en fremragende lukkethet og rissfasthet. It is then pressed in a so-called short stroke press for 120 seconds at 160°C under a pressure of 4 kp/cm<2>. The chipboard coated in this way is removed from the hot press without recooling. Already at this low pressure, surfaces are achieved which exhibit a high degree of gloss, and which are distinguished by their excellent sealing and crack resistance.
