Description
Fremgangsmåte til fremstilling av ildhemmende barriere-eller kjernefilm. Process for the production of fire-retardant barrier or core film.
Oppfinnelsen vedrører en fremgangsmåte til fremstilling av et med herbare fenolformaldehydharpikser impregnert papir som kan anvendes som kjernefilm for ildhemmende lagpress-stoffer resp. som ildhemmende belegningsfilm (barrierefilm) ved brennbare trematerialer, og idet fenolformaldehydharpiksen inneholder ildhemmende nitrogen-fosfor-forbindelser. The invention relates to a method for producing a paper impregnated with curable phenol-formaldehyde resins which can be used as a core film for fire-retardant laminated materials or as a fire-retardant coating film (barrier film) for combustible wood materials, and as the phenol-formaldehyde resin contains fire-retardant nitrogen-phosphorus compounds.
Til lagpress-stoffer stilles meget ofte det krav at de skal være tungt brennbare resp. ha. ildhemmende egenskaper. Disse krav møter man spesielt når slike materialer anvendes i skipsbygning ved fremstilling av ferdighus og lignende. Layer press materials are very often required to be highly flammable or have. flame retardant properties. These requirements are particularly encountered when such materials are used in shipbuilding in the manufacture of prefabricated houses and the like.
Man har tidligere i første rekke forsøkt å oppnå disse egenskaper ved at man appreterer de bærebaner hvorav disse lagpress-stof f er er oppbygget med i det vesentlige uorganiske fyllstoffer. Således har man f.eks. som bærebaner anvendt papirbaner som inneholder større mengder antimonoksyd. Den ildhemmende virkning av antimonoksyd kan dessuten økes ved at man i tillegg tilsetter i varmen klorhydrogen-avgivende forbindelser. In the past, attempts have primarily been made to achieve these properties by preparing the carrier webs of which these layered press fabrics are built up with essentially inorganic fillers. Thus, one has e.g. paper webs containing larger amounts of antimony oxide are used as carrier webs. The fire-retardant effect of antimony oxide can also be increased by additionally adding chlorine-hydrogen-releasing compounds to the heat.
Man har også behandlet det ferdige papir med salt-oppløsninger. Derved betjener man seg i første rekke av ammonium-salter som f.eks. av ammoniumfosfat og ammoniumbromid. Også alkali-borater er allerede anvendt for dette formål. The finished paper has also been treated with salt solutions. Thereby, one uses primarily ammonium salts such as e.g. of ammonium phosphate and ammonium bromide. Also alkali borates have already been used for this purpose.
Man kan også til harpiksoppløsningene sette ammonium-salter, spesielt ammoniumfosfater. Imidlertid er det for slike tilsetninger satt grenser ved at over en bestemt mengde virker det til-satte ammoniumfosfat utsaltende og den vandige fenolharpiksoppløs-ning adskiller seg i to sjikt, hvorav det ene i det vesentlige inneholder fenolharpiksen og det andre i det vesentlige ammoniumfosfatet. Man kan delvis imøtegå disse vanskeligheter ved at man overholder snevert begrensede konsentrasjoner resp. anvender hjelpeoppløsnings-middel. Imidlertid forblir det også i disse tilfelle som ulempe at den herdede film på grunn av nærvær av vannoppløselig ammoniumfosfat i forholdsvis stor grad er vannfølsom og derfor har ugunstige bruksegenskaper. Ammonium salts, especially ammonium phosphates, can also be added to the resin solutions. However, limits have been set for such additives in that above a certain amount the added ammonium phosphate has a salinizing effect and the aqueous phenolic resin solution separates into two layers, one of which essentially contains the phenolic resin and the other essentially the ammonium phosphate. These difficulties can be partially countered by adhering to narrowly limited concentrations or uses auxiliary solvent. However, it also remains a disadvantage in these cases that the cured film is relatively water sensitive due to the presence of water-soluble ammonium phosphate and therefore has unfavorable application properties.
Overraskende ble det nå funnet at de ovenfor omtalte ulemper på enkel måte kan overvinnes ved at man til den vandige opp-løsning av en fenolformaldehydharpiks ved siden av fosforsyre og ammoniakk setter bestemte mengder formaldehyd. Surprisingly, it has now been found that the disadvantages mentioned above can be overcome in a simple way by adding certain amounts of formaldehyde to the aqueous solution of a phenol formaldehyde resin next to phosphoric acid and ammonia.
Fremgangsmåten ifølge oppfinnelsen er følgelig karakterisert ved at man til en oppløsning av fenolformaldehydharpiks setter 0,05 til 0,15 mol fosforsyre pr. mol fenol og minst 3 mol ammoniakk pr. mol fosforsyre og så meget formaldehyd at minst 1 mol formaldehyd pr. mol ammoniakk foreligger i en til fenol ikke bundet form, hvorpå papiret impregneres med nevnte oppløsning på kjent måte. The method according to the invention is consequently characterized by adding 0.05 to 0.15 mol of phosphoric acid per mol to a solution of phenol formaldehyde resin. mol of phenol and at least 3 mol of ammonia per mol of phosphoric acid and so much formaldehyde that at least 1 mol of formaldehyde per moles of ammonia is present in a form not bound to phenol, after which the paper is impregnated with said solution in a known manner.
Det er selvsagt også mulig istedenfor de enkelte kom-ponenter, fosforsyre, ammoniakk og formaldehyd, å anvende omsetnings-produkter av disse forbindelser. Således kan man eksempelvis istedenfor fosforsyre og ammoniakk tilsette tertiært ammoniumfosfat eller primært resp. sekundært ammoniumfosfat og tilsvarende mengder ammoniakk til den vandige fenolformaldehydharpiksoppløsning. Man kan også først la ammoniumfosfat reagere med formaldehyd og til oppløs-ningen sette et omsetningsprodukt, som man eksempelvis får ved reak-sjon med 1 mol fosforsyre, 3 mol ammoniakk og 3 mol formaldehyd. De angitte minstemengder av ammoniakk og formaldehyd kan overskrides, da et overskudd av disse forbindelser ikke influerer på fremgangs-måteproduktenes bruksegenskaper. Mengden av fosforsyre, nemlig 0,05 til 0,15 mol pr. mol fenol, angir den mengde som man hensiktsmessig anvender ved en økonomisk arbeidsmåte. Man kan også øke mengden av fosforsyre, imidlertid forbedres ikke vesentlig ildbe-standigheten ved ytterligere tilsetninger, men vannbestandigheten blir stadig dårligere. It is of course also possible to use reaction products of these compounds instead of the individual components, phosphoric acid, ammonia and formaldehyde. Thus, for example, instead of phosphoric acid and ammonia, you can add tertiary ammonium phosphate or primary resp. secondary ammonium phosphate and corresponding amounts of ammonia to the aqueous phenol formaldehyde resin solution. You can also first let ammonium phosphate react with formaldehyde and add a reaction product to the solution, which is obtained, for example, by reacting with 1 mol of phosphoric acid, 3 mol of ammonia and 3 mol of formaldehyde. The stated minimum amounts of ammonia and formaldehyde can be exceeded, as an excess of these compounds does not influence the performance of the process products. The amount of phosphoric acid, namely 0.05 to 0.15 mol per moles of phenol, indicates the quantity that is appropriately used in an economical way of working. You can also increase the amount of phosphoric acid, however, the fire resistance is not significantly improved by further additions, but the water resistance becomes progressively worse.
Hensiktsmessig blir ved fremgangsmåten ifølge oppfinnelsen formaldehyd tilsatt i form av dets vandige oppløsning. Det er selvsagt også mulig i stedet for fritt formaldehyd å anvende slike forbindelser som frigjør formaldehyd, som f.eks. paraformaldehyd. Appropriately, in the method according to the invention, formaldehyde is added in the form of its aqueous solution. It is of course also possible instead of free formaldehyde to use such compounds which release formaldehyde, such as e.g. paraformaldehyde.
Fremgangsmåten ifølge oppfinnelsen skal forklares ved hj elp av følgende eksempler. The method according to the invention will be explained with the help of the following examples.
Den for forsøkene anvendte fenolharpiks kondenseres på vanlig måte av 1 mol fenol, 1,25 mol paraformaldehyd, 0,25 mol formalin, 30$-ig, og 0,025 mol natriumhydroksyd ved temperaturer på ca. 70°c under tilbakeløpskjøling. Reaksjonstemperaturen økes etter den eksoterme reaksjons avslutning til 85 til 90°C, inntil det er oppnådd en viskositet som gir en utløpstid på 80 til 120 sekunder i et DIN-beger med en 4 mm dyse ved en temperatur på 20°C. Den ferdige harpiksoppløsning har en konsentrasjon på 89%. Eksempler. The phenol resin used for the experiments is condensed in the usual way from 1 mol of phenol, 1.25 mol of paraformaldehyde, 0.25 mol of formalin, 30$-ig, and 0.025 mol of sodium hydroxide at temperatures of approx. 70°c under reflux cooling. The reaction temperature is increased after the end of the exothermic reaction to 85 to 90°C, until a viscosity has been obtained which gives an outflow time of 80 to 120 seconds in a DIN beaker with a 4 mm nozzle at a temperature of 20°C. The finished resin solution has a concentration of 89%. Examples.
A) Fremstilling av harpiksen ifølge oppfinnelsen. A) Production of the resin according to the invention.
Al) 1565 g fenolformaldehydharpiks som fremstilles på ovenfor omtalte måte blandes med 90 g vann, 750 g 30%- ig formalin, 172 g 25^-ig ammoniakkoppløsning og 163,2 g sekundært ammoniumfosfat . Den således dannede harpiksoppløsning er klar og har en pH-verdi på ca. 4,5. Harpiksoppløsningen er 63,6%-ig. Al) 1565 g of phenol formaldehyde resin, which is produced in the manner mentioned above, is mixed with 90 g of water, 750 g of 30% formalin, 172 g of 25% ammonia solution and 163.2 g of secondary ammonium phosphate. The resin solution thus formed is clear and has a pH value of approx. 4.5. The resin solution is 63.6%.
Sammenblander man de ovennevnte bestanddeler i de angitte mengder imidlertid uten tilsetning av formalin, så får man ingen klar harpiksoppløsning. Ammoniumfosfatet utkrystalliserer også ved høyere tilsetning av vann eller metanol. However, if the above-mentioned ingredients are mixed together in the indicated amounts without the addition of formalin, no clear resin solution is obtained. The ammonium phosphate also crystallizes when more water or methanol is added.
A 2) 1565 g av den som angitt ovenfor fremstilte fenolharpiks tilsettes 225 g paraformaldehyd, oppløst i 302,8 g vann. A 2) 225 g of paraformaldehyde, dissolved in 302.8 g of water, is added to 1565 g of the phenolic resin prepared as stated above.
En oppvarraning ved 80°C begunstiger oppløsningen. Deretter tilsettes 162j2 g metanol, 172 g 25%- ig ammoniakkoppløsning og 163,2 g sekundært ammoniumfosfat. Man får igjen en klar harpiksoppløsning med en pH-verdi på ca. H, 5, som inneholder 70, 5% faste bestanddeler. B) Fremstilling av filmen ifølge oppfinnelsen. Warming at 80°C favors dissolution. 162j2 g of methanol, 172 g of 25% ammonia solution and 163.2 g of secondary ammonium phosphate are then added. A clear resin solution with a pH value of approx. H, 5, which contains 70.5% solids. B) Production of the film according to the invention.
Med de ifølge eksempel A 1 eller A 2 ifølge oppfinnelsen fremstilte harpiksoppløsninger fuktes et sugedyktig, ulimt natronkraftpapir av 150 g/m<2> som inneholder 20 vektprosent kaolin og tørkes ved 130°C. Etter impregnering og tørkning har den dannede film en flatevekt på 250 g/m2 og et innhold av flyktige bestanddeler på 7j5 til-9*0$. Filmen kan oppvikles på ruller uten å sammenklebes eller brytes. With the resin solutions prepared according to example A 1 or A 2 according to the invention, an absorbent, unglued soda paper of 150 g/m<2> containing 20 percent by weight of kaolin is moistened and dried at 130°C. After impregnation and drying, the formed film has a basis weight of 250 g/m 2 and a content of volatile constituents of 7.5 to -9.0%. The film can be wound on rolls without sticking together or breaking.
C) Forarbeidelse av filmen ifølge oppfinnelsen. C) Processing of the film according to the invention.
C 1) Fremstilling av et lagpress-stoff. C 1) Production of a layer press fabric.

C 2) Sponplatebelegning med filmen ifølge oppfinnelsen som barrierefilm. C 2) Chipboard coating with the film according to the invention as a barrier film.
En melaminharpiksdekorfilm av 200 g/m , 8 lag av A melamine resin decorative film of 200 g/m , 8 layers of
filmen ifølge oppfinnelsen og en fenolharpiksfilm; på 180 g/m på-presses sammen på en'10 mm tykk normal tresponplate. Presstiden ut-gjør 11 minutter, presstemperaturen 145°C og presstrykket 20 kg/cm<2>. De enkelte filmlag kieber ved disse pressbetingelser meget godt til hverandre og lar seg heller ikke etter lengere lagringer i vann skille fra hverandre. D) Brannprøving av platene fremstilt med filmen ifølge oppfinnelsen. the film of the invention and a phenolic resin film; of 180 g/m is pressed together on a 10 mm thick normal chipboard. The pressing time is 11 minutes, the pressing temperature 145°C and the pressing pressure 20 kg/cm<2>. Under these pressure conditions, the individual film layers adhere very well to each other and do not allow themselves to separate from each other after longer storage in water. D) Fire testing of the plates produced with the film according to the invention.
Brannprøvingene ble gjennomført etter de meget strenge metoder ifølge Statens Provningsanstalt Stockholm (Box-metode). Ved denne prøve er platene utsatt for innvirkning av en justert propan-gassflamme. Ved hjelp av et termoelement måles temperaturen av de uttredende røkgasser og opptegnes ved hjelp av en temperaturskriver. Samtidig måles ved hjelp av en lampe og en fotocelle tettheten av den uttredende røk og angis i prosent av absorbert lys. Den ifølge eksempel C 1 fremstilte lagstoffplate ble pålimt ved hjelp av et koldherdende fenolharpikslim på en 10 mm sponplate og deretter klimatisert i normalt klima. Den ifølge eksempel C 2 fremstilte belagte sponplate ble bare klimatisert og deretter undersøkt. The fire tests were carried out according to the very strict methods according to the Statens Provningsanstalt Stockholm (Box method). In this test, the plates are exposed to the influence of an adjusted propane gas flame. Using a thermocouple, the temperature of the exiting flue gases is measured and recorded using a temperature recorder. At the same time, using a lamp and a photocell, the density of the escaping smoke is measured and expressed as a percentage of absorbed light. The laminated board produced according to example C 1 was glued using a cold-hardening phenolic resin adhesive on a 10 mm chipboard and then conditioned in a normal climate. The coated chipboard produced according to example C 2 was only conditioned and then examined.
Resultat: I begge prøver lå røkgasstemperaturen bare maksimalt 40°C over nullkurven, mens røkgasstettheten ga en maksimal lysabsorpsjon på 5%. Platene har altså i meget utmerket grad be-stått brannprøven. Result: In both samples, the flue gas temperature was only a maximum of 40°C above the zero curve, while the flue gas density gave a maximum light absorption of 5%. The plates have therefore passed the fire test very well.
Ved et med normal kjernefilm fremstilt lagstoff stiger røkgasstemperaturen derimot omtrent 200-i|00°C over nullkurven. In the case of a laminate made with a normal core film, on the other hand, the flue gas temperature rises approximately 200-100°C above the zero curve.
