Description
Oppfinnelsen vedrører en fremgangsmåte for fremstilling av dimensjons-stabile, plane materialer av celluloseholdig materiale, hvilket er belagt på den ene siden og som p.g.a. egen-artede fysikalske egenskaper for celluloseholdig materiale, som på den ene siden er påført et belegg, har en tendens til å slå seg, bøye seg eller på annen måte miste den plane formen. The invention relates to a method for producing dimensionally stable, planar materials of cellulose-containing material, which is coated on one side and which, due to peculiar physical properties of cellulosic material, which is coated on one side, tends to buckle, bend or otherwise lose its planar shape.
Materialer av celluloseholdig materiale er, så snart de blir belagt på den ene siden, ikke dimensjons-stabile, d.v.s. de slår seg, og plane materialer bøyer seg, mer eller mindre avhen-gig av platens tykkelse. Således har f.eks. papirbaner, papp, hardfiberplater av slipmasse eller annet celluloseholdig materiale, eller vulkanfiberplater, hvis de har belegg på den ene siden, den ufordelaktige egenskap at de alt etter luftfuktigheten slår seg mer eller mindre. Dette vanskeliggjør i de fleste tilfeller anvendelsen og den fulle utnyttelse av f.eks. slipebånd, smergelpapir eller slipepapir, så vel som selvklebende folier eller selvklebende tapeter. Hardfiberplater av tremateri-ale eller cellulosemasser anvendes ved møbeltilvirkning, for hus-vogner og i karosseri-innredninger. De anvendes videre som bygge-elementer i ferdighus. Ved anvendelsen av ensidig belagte hardfiberplater kan en deformasjon bevirke en forvridning, og de av platene tilvirkede artikler kan få et stygt utseende. Også sam-menføynings—arbeider som forekommer i byggebransjen, f.eks. liming eller sammenspikring, kan p.g.a. denne deformeringsfare bare gjennomføres med vanskelighet,og uten at man kan gi en garanti for holdbarheten. Den eneste kjente motforholdsregel overfor forvridning besto i at slike plater eller papirark ble symmetrisk belagt på begge sider og på samme måte. Dette er imidlertid -i praksis nesten, aldri mulig å realisere. Materials of cellulosic material are, as soon as they are coated on one side, not dimensionally stable, i.e. they buckle, and flat materials bend, more or less depending on the thickness of the plate. Thus, e.g. paper webs, cardboard, hard fiber boards made of sanding compound or other cellulose-containing material, or volcanic fiber boards, if they have a coating on one side, the disadvantageous property that, depending on the humidity, they settle more or less. This makes it difficult in most cases to apply and fully utilize e.g. sanding tape, emery paper or sandpaper, as well as self-adhesive foils or self-adhesive wallpaper. Hard fiber boards made of wood material or cellulose pulp are used in furniture production, for house-carts and in body fittings. They are further used as building elements in prefabricated houses. When using one-sided coated hard fiber boards, a deformation can cause a distortion, and the articles made from the boards can have an ugly appearance. Also joining work that occurs in the construction industry, e.g. gluing or nailing together, can due to this danger of deformation is only carried out with difficulty, and without being able to give a guarantee for durability. The only known countermeasure against warping was that such plates or sheets of paper were symmetrically coated on both sides and in the same way. However, this is -in practice almost, never possible to realize.
Med nærværende oppfinnelse var det en.oppgave å fremskaffe en behandlingsmåte slik at disse uheldige egenskaper hos belagte materialer av celluloseholdig materiale ikke lenger fikk gjøre seg gjeldende, dvs. at disse materialer blir dimensjons-stabile. With the present invention, it was one task to provide a treatment method so that these unfortunate properties of coated materials of cellulose-containing material could no longer apply, i.e. that these materials become dimensionally stable.
Denne oppgave ble overraskende løst- ved hjelp av en fremgangsmåte for fremstilling av dimensjons-stabile, ensidig overtrukne, plane gjenstander av celluloseholdig materiale., i form av papir--baner , plater eller .•folier-., hvilke gjenstander, .på den ene side er forsynt med et overtrekk, eventuelt i form av en påpresset folie, som dekker materialet lufttett, hvorved man umiddelbart før eller etter påføring av det ensidige overtrekk eller etter herding av dette eller etter gjenfuktning av materialet i tilslutning til en herdeprosess påfører en 0,1-50%'s, fortrinnsvis 3-10%'s, oppløsning av en silikonolje og fordamper oppløsnings-midlet, og karakteristisk er at man påfører silikonoljeoppløs-ningen på den ikke overtrukne, porøse side -av gjenstanden, i en mengde på 1-30 g/m 2og bringer oppløsningsmidlet til å fordampe etter at det har trengt inn i materialets porer. This task was surprisingly solved by means of a method for the production of dimensionally stable, one-sided coated, planar objects of cellulose-containing material, in the form of paper webs, plates or foils, which objects, on the one side is provided with a cover, possibly in the form of a pressed-on foil, which covers the material airtight, whereby immediately before or after applying the one-sided cover or after curing this or after rewetting the material in connection with a curing process, a 0 ,1-50%'s, preferably 3-10%'s, solution of a silicone oil and evaporates the solvent, and it is characteristic that the silicone oil solution is applied to the non-coated, porous side of the object, in an amount of 1-30 g/m 2 and causes the solvent to evaporate after it has penetrated the pores of the material.
Fra norsk patentskrift nr. 99.052 er det riktignok kjent å på-føre en oppløsning av silikonolje i toluen på en trefiberplate, umiddelbart etter at platen er belagt med en PVC-pasta og ført gjennom en varmekanal. Det sies imidlertid ikke hvilken side av platen som ble behandlet med silikonolje-oppløsningen. From Norwegian patent document no. 99,052 it is admittedly known to apply a solution of silicone oil in toluene to a wooden fiberboard, immediately after the board has been coated with a PVC paste and passed through a heating channel. However, it is not said which side of the plate was treated with the silicone oil solution.
Ifølge oppfinnelsen anvendes fortrinnsvis hydrofile løsnings-midler for silikonoljen. De anvendes alene eller i blanding med andre organiske løsningsmidler. According to the invention, hydrophilic solvents are preferably used for the silicone oil. They are used alone or in a mixture with other organic solvents.
"Dimensjons-stabil" betyr her at materialet av celluloseholdig materiale ikke kaster seg eller vrir seg, at det ikke krummer seg eller bøyer seg eller på annen måte forandrer formen. "Dimensional stable" here means that the material of cellulosic material does not warp or twist, that it does not curve or bend or otherwise change its shape.
Den nevnte enkle etterbehandling :ifølge oppfinnelsen resulterte overraskende i en fullkommen og varig eliminering av deforma-sjons-fenomenene. The aforementioned simple post-treatment according to the invention surprisingly resulted in a complete and permanent elimination of the deformation phenomena.
Ensidig belagte materialer, så som slipebånd, smergelpapir og slipepapir, så vel som hardfiberplater, behandlet etter fremgangsmåten ifølge oppfinnelsen, kan anvendes og bearbeides vesentlig lettere enn tidligere. Lagringsforsøk under forskjellige betingelser og over lengere tidsrom viste.en permanent dimensjons-stabilitet. Man fant videre at overflaten var vesentlig glattere og smidigere. ...Egnede silikonoljer er metyl-, metylpoly-,.metylfenyl- og metyl-fenylpoly-siloksanex, hvorved organosubstituenter av samme eller forskjellig type kan forekomme, som f.eks. produkter med etyl-og metyl-hydrogengrupper, så vel som slike organo-funksjonelle grupper som f-eks. &-cyanoetyl-, y-cyanopropyl-, Jf-trifluorpro-pyl-f 5-aminobutyl- og tetraklorfenyl-grupper. Man erholder silikonoljer ifølge kjente fremgangsmåter ved hydrolyse av klor-silaner og etterfølgende kondensasjon, henholdsvis polymerisa-sjon, til cykliske eller rettkjedede polysiloksaner. Silikonoljer er klare, fargeløse, nøytrale og nesten luktfrie væsker, med en viskositet mellom 0,65 og 1 000 000 centistoke, og en molekylvekt mellom 600 og 400 000. One-sided coated materials, such as sanding belts, emery paper and sanding paper, as well as hard fiber boards, treated according to the method according to the invention, can be used and processed much easier than before. Storage tests under different conditions and over longer periods of time showed a permanent dimensional stability. It was also found that the surface was significantly smoother and more flexible. ...Suitable silicone oils are methyl-, methylpoly-,.methylphenyl- and methyl-phenylpoly-siloxanex, whereby organosubstituents of the same or different type can occur, such as e.g. products with ethyl and methyl hydrogen groups, as well as such organo-functional groups as e.g. ?-cyanoethyl-, y-cyanopropyl-, Jf-trifluoropropyl-f 5-aminobutyl- and tetrachlorophenyl groups. Silicone oils are obtained according to known methods by hydrolysis of chlorosilanes and subsequent condensation, respectively polymerization, to cyclic or straight-chain polysiloxanes. Silicone oils are clear, colorless, neutral and almost odorless liquids, with a viscosity between 0.65 and 1,000,000 centistokes, and a molecular weight between 600 and 400,000.
Silikonoljene er løselige i mange organiske løsningsmidler, så som alifatiske hydrokarboner:, aromatiske hydrokarboner, estere, videre dimetylsulfoksyd og dimetylformamid. Fortrinnsvis anvendes hydrof ile løsningsmidler, så som alkoholer, og da spesielt etyl-, propyl-, butyl-, i-sopropyl-, isobutylalkohol, videre ety-lenglykol, dennes etere og estere og glyserol. Som ytterligere eksempler kan nevnes propylenglykol, butyldiglykol og andre poly-glykoler. Løsningsmidlene kan anvendes hver for seg eller i blan-dinger. The silicone oils are soluble in many organic solvents, such as aliphatic hydrocarbons:, aromatic hydrocarbons, esters, further dimethylsulfoxide and dimethylformamide. Hydrophilic solvents are preferably used, such as alcohols, and in particular ethyl, propyl, butyl, isopropyl, isobutyl alcohol, further ethylene glycol, its ethers and esters and glycerol. As further examples, propylene glycol, butyl diglycol and other poly-glycols can be mentioned. The solvents can be used individually or in mixtures.
Påføringen av silikonoljeløsningen på den ikke-belagte siden The application of the silicone oil solution on the non-coated side
av materialet skjer ifølge vanlige metoder,som f.eks. ved på-børsting, påhelling, påsprøyting eller påvalsing. of the material takes place according to usual methods, such as e.g. by brushing on, pouring on, spraying on or rolling on.
Fremgangsmåten ifølge oppfinnelsen er arvendbar på alle celluloseholdige materialer som skal belegges på den ene siden. Med "celluloseholdige materialer" forstås alle materialer hvor et celluloseholdig materiale utgjør den ytre flate. Egnede materialer er papp, papir, folier av cellulosemateriale, hardfiberplater, sammensatte plater, plywood-plater og plater av vulkan-fibre. The method according to the invention is applicable to all cellulose-containing materials which are to be coated on one side. "Cellulosic materials" means all materials where a cellulose-containing material forms the outer surface. Suitable materials are cardboard, paper, foils of cellulose material, hard fiber boards, composite boards, plywood boards and boards made of volcanic fibers.
Materialet er ensidig overtrukket med et sjikt som lukker det lufttett overfor den omgivende atmosfære. Derved kan "pustingen" til det celluloseholdige materialet så vel som fuktighetsutveks-ling ved "varierende luftfuktighet bare skje via den ikke-belagte siden. The material is coated on one side with a layer that seals it airtight against the surrounding atmosphere. Thereby, the "breathing" of the cellulose-containing material as well as moisture exchange in the event of "varying air humidity" can only take place via the non-coated side.
Det nevnte lufttette sjikt kan være av uorganisk eller organisk natur. Således kan man anvende kunstharpikser så som urea/form-aldehyd-, melamin/formaldehyd- eller fenol/formaldehyd-harpikser, alkyd-, polyester- og polyamidharpikser, epoksydforbindelser, polyuretaner, polysulfider, polybutadien, klorkautsjuk, polyety-len, polypropylen og mange andre- The aforementioned airtight layer can be of an inorganic or organic nature. Thus, one can use artificial resins such as urea/formaldehyde, melamine/formaldehyde or phenol/formaldehyde resins, alkyd, polyester and polyamide resins, epoxy compounds, polyurethanes, polysulfides, polybutadiene, chlorinated rubber, polyethylene, polypropylene and many second-
I kunstharpiksen kan videre fargestoffer være inkorporert, pig-menter og videre hardt pulver av forskjellig finhetsgrad, så som f.eks. smergel,kvartssand, glasspulver, siliciumkarbid, pimp-sten, aluminiumoksyd, kiselgur, o.s.v.. In the artificial resin, further dyes can be incorporated, pigments and further hard powders of different degrees of fineness, such as e.g. emery, quartz sand, glass powder, silicon carbide, pumice stone, aluminum oxide, diatomaceous earth, etc.
Belegget kan videre bestå av uorganisk materiale, f.eks. av vann-glass . The coating can also consist of inorganic material, e.g. of water-glass.
Belegningen kan skje på kjent måte ved påvalsing, påsprøyting, ved å kalandrere beleggmidlet fra løsninger i organiske løsnings-midler eller fra vandige dispersjoner. Det er også mulig å presse på folier. Til slutt kan man på vanli-g måte foreta tørking og herding. Etter herdingen,som vanligvis foretas ved høyere temperaturer,inneholder det celluloseholdige materiale bare små mengder fuktighet. For å avstedkomme likevekt med hensyn til luftfuktigheten foretar man etter herdingsprosessen vanligvis en gjen-fukting ved å sprøyte vann på den ikke-belagte siden. The coating can take place in a known manner by rolling, spraying, by calendering the coating agent from solutions in organic solvents or from aqueous dispersions. It is also possible to press on foils. Finally, drying and curing can be carried out in the usual way. After curing, which is usually carried out at higher temperatures, the cellulosic material contains only small amounts of moisture. In order to achieve equilibrium with respect to the air humidity, after the curing process a re-moistening is usually carried out by spraying water on the non-coated side.
Ved fremgangsmåten ifølge oppfinnelsen skjer som sagt påføringen av silikonoljeløsningen før eller etter herdeprosessen og før eller etter at man igjen foretar fukting. In the method according to the invention, as said, the application of the silicone oil solution takes place before or after the curing process and before or after wetting is carried out again.
De etter fremgangsmåten ifølge oppfinnelsen behandlede materialer kan anvendes for mange formål. Således kan man fremstille slipepapir og slipebånd av dimensjons-stabil form. Hardfiberplater og plywood-plater kan anvendes i møbelindustrien, husvogn-indu-strien og bygningsindustrien. Også vulkanfiberplater forblir dimensjons-stabile. Ytterligere anvendelsesområder er behandling av selvklebende folier, selvklebende tapeter og frimerker. The materials treated according to the method according to the invention can be used for many purposes. Thus, it is possible to produce sanding paper and sanding belts of dimensionally stable form. Hard fiber boards and plywood boards can be used in the furniture industry, the caravan industry and the construction industry. Vulcan fiber boards also remain dimensionally stable. Further areas of application are the treatment of self-adhesive foils, self-adhesive wallpaper and stamps.
Følgende eksempler skal anskueliggjøre- fremgangsmåten ifølge oppfinnelsen. Alle prosentangivelser henfører seg til vektspro-sent; alle deler henfører seg til vektsdeler. The following examples will illustrate the method according to the invention. All percentages refer to percentage by weight; all parts refer to parts by weight.
