Description
Foreliggende oppfinnelse angår en fremgangsmåte for behandling av en folie som på minst én overflate gis en endelig overflatebehandling ved impregnering og flatebe-handling, der det er hensikten å feste folien på bærere, f.eks. på fiberplater, finérplater, paneler og lignende. The present invention relates to a method for treating a foil which on at least one surface is given a final surface treatment by impregnation and surface treatment, where the purpose is to attach the foil to carriers, e.g. on fiber boards, veneer boards, panels and the like.
Med bakgrunn i rasjonaliseringsbestrebelsene i møbel-industrien er det et stort behov for prefabrikerte flater, dvs. flater som det ikke er nødvendig å male. Dette behov er hittil i stor utstrekning blitt dekket ved å benytte melaminimpregnerte, trykte og ikke trykte papirbaner som f.eks. blir presset på fiberplaten eller møbeldelen ved forhøyet temperatur og trykk. Av forskjellige årsaker får disse overflater brukbare egenskaper, men kan ikke fra et estetisk synspunkt sammenlignes med en flate som er malt på vanlig måte. Against the background of the rationalization efforts in the furniture industry, there is a great need for prefabricated surfaces, i.e. surfaces that do not need to be painted. This need has so far been met to a large extent by using melamine-impregnated, printed and unprinted paper webs such as e.g. is pressed onto the fiberboard or furniture part at elevated temperature and pressure. For various reasons, these surfaces acquire usable properties, but cannot be compared from an aesthetic point of view to a surface that has been painted in the usual way.
Det har vært foretatt forsøk på å kombinere slik mela-minimpregnering med et etterfølgende dekklag ved bruk av malingskomponenter for å gi flaten et malt utseende og tilsvarende egenskaper. Denne fremgangsmåte har imidlertid ikke gitt tilfredsstillende resultater, ganske enkelt på grunn av at papir eller papp som skal kunne impregneres må ha store porer for å lette impregneringen, mens det etterfølgende dekklag tvert imot krever tett papir for å Attempts have been made to combine such melamine impregnation with a subsequent covering layer using paint components to give the surface a painted appearance and corresponding properties. However, this method has not given satisfactory results, simply because the paper or cardboard to be impregnated must have large pores to facilitate the impregnation, while the subsequent covering layer, on the contrary, requires dense paper to
gi godt resultat. give good results.
Det har nå overraskende vist seg at problemet, som består i å få et tilfredsstillende produkt ved kombinert impregnering og belegging, kan løses på følgende måte. It has now surprisingly turned out that the problem, which consists of obtaining a satisfactory product by combined impregnation and coating, can be solved in the following way.
Ved å utføre impregneringen i en papirmaskin før slutt-tørkingen blir det mulig å fremstille et tett papir med et harpiksinnhold som er stort nok til å gi et godt resultat ved den etterfølgende belegging. Påføringen av harpiksen kan utføres på forskjellige måter, avhengig av de krav som stilles til det ferdige produkt og av det tekniske utstyr, By carrying out the impregnation in a paper machine before the final drying, it becomes possible to produce a dense paper with a resin content that is large enough to give a good result in the subsequent coating. The application of the resin can be carried out in different ways, depending on the requirements placed on the finished product and on the technical equipment,
og harpikstørrstoffinnholdet kan også varieres i tilsvarende grad innenfor så vide grenser som 5 til 60 vektprosent, basert på vekten av papir og harpiks. En særlig foretruk-ket størrelsesorden med hensyn på tørrstoffinnholdet er and the resin solids content can also be varied to a corresponding extent within such wide limits as 5 to 60 percent by weight, based on the weight of paper and resin. A particularly preferred order of magnitude with regard to the dry matter content is
15 til 40 vektprosent på samme basis. 15 to 40 percent by weight on the same basis.
Foreliggende oppfinnelse går således ut på en overflatebehandling av folie bestemt for anbringelse på et bærende underlag, f.eks. sponplater, finér eller lignende, og oppfinnelsen karakteriseres ved at i forbindelse med basis- eller grunnfoliens fremstilling i papirmaskin til-føres impregneringsmiddel i form av en termoplast eller termo-herdende plast som er forenlig med eller oppløselig i vann til et fibermateriale på cellulosebasis før slutt-tørkingen, eksempelvis i en mengde av 5 til 6 0 vektprosent regnet på ferdigvekten, og meddeles en porøsitet ifølge Gurley av minst 12 sek/100 ml, samt deretter før dets endelige anvendelse etterbehandles under overflatebehandling ved påføring av en blanding av pigment og bindemiddel og eventuelt også farvestoff. The present invention thus concerns a surface treatment of foil intended for placement on a supporting substrate, e.g. chipboard, veneer or the like, and the invention is characterized by the fact that, in connection with the production of the base or base film in a paper machine, an impregnating agent in the form of a thermoplastic or thermosetting plastic that is compatible with or soluble in water is added to a cellulose-based fiber material before finishing - the drying, for example in an amount of 5 to 60 percent by weight calculated on the finished weight, and a porosity according to Gurley of at least 12 sec/100 ml is given, and then before its final use it is finished during surface treatment by applying a mixture of pigment and binder and possibly also dye.
Ved fremgangsmåten ifølge oppfinnelsen har grunnma-terialet i den impregnerte film en porøsitet ifølge Gurley på minst 12 sek/100 ml. Det impregnerte materiale blir til slutt overflatebelagt ved påføring av en blanding av pigmenter og bindemiddel, og det er også mulig å tilføye en fargingskomponent. Impregneringsmidlet er fortrinnsvis en vandig harpiksoppløsning eller -dispersjon. In the method according to the invention, the base material in the impregnated film has a porosity according to Gurley of at least 12 sec/100 ml. The impregnated material is finally surface-coated by applying a mixture of pigments and binder, and it is also possible to add a coloring component. The impregnating agent is preferably an aqueous resin solution or dispersion.
Grunnen til at denne fremgangsmåte er særlig fordel-aktig synes å skyldes det faktum at cellulosefibrene i seg selv på i og for seg kjent måte undergår irreversible for-andringer ved tørkingen i en papirmaskin. For at det skal være mulig å foreta den etterfølgende impregnering er det ved fremstillingen av papiret vanligvis nødvendig å gjøre papiret åpent, dvs. fibrene må ikke være for mye oppmalt, idet papiret da får et poresystem som gjør impregneringen lettere. Denne porøsitet vil imidlertid også holde seg etter impregneringen og vil volde vanskeligheter for den etterfølgende belegging. Det er ønskelig å holde den på-førte beleggpasta på flaten, men åpenheten eller porøsi-teten i papiret fører til at belegget i stedet trenger inn i flaten. The reason why this method is particularly advantageous seems to be due to the fact that the cellulose fibers themselves undergo irreversible changes during drying in a paper machine in a manner known per se. In order for it to be possible to carry out the subsequent impregnation, it is usually necessary during the production of the paper to make the paper open, i.e. the fibers must not be ground too much, as the paper then gets a pore system that makes the impregnation easier. However, this porosity will also remain after the impregnation and will cause difficulties for the subsequent coating. It is desirable to keep the applied coating paste on the surface, but the openness or porosity of the paper causes the coating to penetrate into the surface instead.
Hvis imidlertid impregneringen med et impregneringsmiddel, f.eks. av urea- eller melaminharpikstypen, ifølge oppfinnelsen utføres i forbindelse med papirfremstillin-gen før slutt-tørkingen, enten ved tilførsel til massen eller i papirmaskinen ved påsprøyting, i en bestrykningspresse eller et bestrykningsbad eller en kombinasjon av disse, vil det ovennevnte dilemma kunne unngås. Så lenge som papiret ikke er blitt slutt-tørket, vil det beholde sin porøse struktur og er lett å impregnere også ved høyere malingsgrader, slik at det etter slutt-tørkingen oppnås et tettere papir. I dette tilfelle kan også papiret gis en maskinglanset overflate som ytterligere forbedrer resultatet av den etterfølgende belegging. If, however, the impregnation with an impregnating agent, e.g. of the urea or melamine resin type, according to the invention is carried out in connection with the paper production before the final drying, either by supply to the pulp or in the paper machine by spraying, in a coating press or a coating bath or a combination of these, the above-mentioned dilemma will be avoided. As long as the paper has not been final-dried, it will retain its porous structure and is easy to impregnate even at higher levels of paint, so that a denser paper is obtained after the final drying. In this case, the paper can also be given a machine-polished surface, which further improves the result of the subsequent coating.
Den etterfølgende overflatebelegging kan utføres på i og for seg kjent måte. Hvis det anvendes en vanndig dispersjon er det funnet at luftbørster eller -blad gir de beste resultater, men hvis blandingen derimot omfatter opp-løsningsmidler eller flyktige komponenter, vil valsebeleg-ging eller belegging i en såkalt "gardinmaskin" gi de beste resultater. The subsequent surface coating can be carried out in a manner known per se. If an aqueous dispersion is used, it has been found that air brushes or blades give the best results, but if, on the other hand, the mixture includes solvents or volatile components, roller coating or coating in a so-called "curtain machine" will give the best results.
Ved fremgangsmåten ifølge oppfinnelsen vil det i prin-sippet kunne brukes en hvilken som helst type av termoplast eller termoherdende plast som er forenlig med eller opp-løselig i vann. Blant spesielt egnede harpikser kan nevnes materialer av aminoplasttypen, f.eks. urea- eller melamin-harpikser. Det er dessuten mulig å anvende termoherdende plast av fenol-, akryl-, epoxy-, polyuretan- og polyester-typen. In the method according to the invention, any type of thermoplastic or thermosetting plastic that is compatible with or soluble in water can in principle be used. Particularly suitable resins include materials of the aminoplast type, e.g. urea or melamine resins. It is also possible to use thermosetting plastics of the phenol, acrylic, epoxy, polyurethane and polyester type.
Blandingen av pigmenter og bindemiddel som anvendes The mixture of pigments and binder used
i sluttbelegget kan ha en høystvarierende sammensetning i in the final coating can have a highly variable composition i
samsvar med konvensjonell teknikk. Det kan således som pigment anvendes titandioksyd, leire eller kritt. Bindemidlet i dekklagblandingen kan f.eks. bestå av akryl-latex, styren-butadien-latex, melaminharpiks eller ureaharpiks eller bestå av en UV-herdende eller katalysatorherdende polyester eller et bindemiddel av nitrocellulose eller syreherdende typer. Dekklagblandingen kan også innbefatte et fargesettende mid-del hvis dette skulle være ønskelig. compliance with conventional technique. Titanium dioxide, clay or chalk can thus be used as pigment. The binder in the cover layer mixture can e.g. consist of acrylic latex, styrene-butadiene latex, melamine resin or urea resin or consist of a UV-curing or catalyst-curing polyester or a binder of nitrocellulose or acid-curing types. The cover layer mixture can also include a coloring agent if this is desired.
Det cellulosebaserte fibermateriale som grunnfolien består av kan ha som opprinnelig råstoff cellulose, slik som mekanisk masse, kjemisk eller halvkjemisk masse. Den kje-miske masse kan være sulfit- eller sulfatmasse og kan anvendes i bleket, halvbleket eller ubleket form, men det foretrekkes å benytte bleket masse, særlig bleket sulfatmasse . The cellulose-based fiber material of which the base film consists can have cellulose as its original raw material, such as mechanical pulp, chemical or semi-chemical pulp. The chemical pulp can be sulphite or sulphate pulp and can be used in bleached, semi-bleached or unbleached form, but it is preferred to use bleached pulp, especially bleached sulphate pulp.
Oppfinnelsen skal i det følgende beskrives ytterligere ved hjelp av følgende eksempler. I disse eksempler er po-røsiteten angitt ifølge Gurley, og denne porøsitetsverdi bestemmes ifølge standardmetoden SCAN-P 19:66. Selv om det i alle eksempler refereres til bleket sulfatcellulose, skal det bemerkes at alle slags cellulosebaserte fibermaterialer kan anvendes for forming av grunnfolien, f.eks. de ovenfor antydede. In the following, the invention will be described further by means of the following examples. In these examples, the porosity is indicated according to Gurley, and this porosity value is determined according to the standard method SCAN-P 19:66. Although in all examples reference is made to bleached sulphate cellulose, it should be noted that all kinds of cellulose-based fiber materials can be used for forming the base foil, e.g. those indicated above.
Eksempel 1 Example 1
Et papir av omtrent 60 g/m 2 bleket sulfatcellulose ble behandlet under samtidig tilsetning av omtrent 10 vektprosent ureaharpiks (basert på tørr basisvekt) i massen og omtrent 20 vektprosent som sprøytes på papirhanen etter pres-seseksjonen. Ureaharpiksen som ble tilsatt massen var en harpiks med handelsbetegnelsen "Dynorit R L 320" (Dyno Industrier, Norge). Harpiksen som ble påført papirhanen ved påsprøyting var "Kaurit 210" (BASF, Forbundsrepublikken, Tyskland) sammen med 0,02 vektprosent NH.C1 som katalysator. Det impregnerte papir hadde da en flatevekt på o 80 g/m 2 og A paper of about 60 g/m 2 bleached sulfate cellulose was treated with the simultaneous addition of about 10 weight percent urea resin (based on dry basis weight) in the pulp and about 20 weight percent which is sprayed onto the paper tap after the press section. The urea resin that was added to the mass was a resin with the trade name "Dynorit R L 320" (Dyno Industrier, Norway). The resin applied to the paper tap by spraying was "Kaurit 210" (BASF, Federal Republic of Germany) together with 0.02% by weight NH.C1 as a catalyst. The impregnated paper then had a basis weight of o 80 g/m 2 and
en Gurley-porøsitet på 80 sek/100 ml. I en etterfølgende prosess ble papiret belagt med 40 g/m av en pigmentert po-lyesterlakk hvortil det var tilsatt en peroksydkatalysator. Den folie som derved fremkom ble brukt til å kle møbeldeler ved å påføre harpikslim på en fiberplate, derpå påføre folien og feste denne ved pressing i en presse ved et trykk på 10 kp/cm<2> i en tid av 15 sek ved omtrent 140°C. Det er-holdte produkt hadde en hard og glatt overflate som egnet seg som ytre flater i hyller og reoler. a Gurley porosity of 80 sec/100 ml. In a subsequent process, the paper was coated with 40 g/m of a pigmented polyester varnish to which a peroxide catalyst had been added. The resulting foil was used to cover furniture parts by applying resin glue to a fiberboard, then applying the foil and attaching it by pressing in a press at a pressure of 10 kp/cm<2> for a time of 15 sec at approximately 140 °C. The existing product had a hard and smooth surface that was suitable as outer surfaces in shelves and racks.
Eksempel 2 Example 2
Et papir av omtrent 100 g/m 2 av bleket sulfatcellulose ble impregnert ved midten av tørkeseksjonen i en papirmaskin ved hjelp av et innskutt bad, med 40 g/m 2 melaminharpiks, slik at man fikk en maskinglanset overflate på papiret. Den melaminharpiks som ble anvendt var "Kauramin R 772" A paper of about 100 g/m 2 of bleached sulphate cellulose was impregnated at the center of the drying section of a paper machine by means of an interposed bath, with 40 g/m 2 of melamine resin, so that a machine gloss surface was obtained on the paper. The melamine resin used was "Kauramin R 772"
(en vanndig oppløsning av et kondensasjonsprodukt av urea-formaldehyd fra BASF, Forbundsrepublikken Tyskland) sammen med 0,025 vektprosent HCOOH som katalysator. Etter slutt-tørking av papiret hadde dette en flatevekt på 140 g/m 2. Porøsiteten var 35 sek/100 ml. Papiret ble derpå belagt (an aqueous solution of a urea-formaldehyde condensation product from BASF, Federal Republic of Germany) together with 0.025% by weight HCOOH as a catalyst. After final drying of the paper, this had a basis weight of 140 g/m 2. The porosity was 35 sec/100 ml. The paper was then coated
i to trinn med titandioksydpigmentert melaminoppløsning. in two stages with titanium dioxide pigmented melamine solution.
Den tilførte mengde var 25 g/m 2. Som i eksempel 1 ble folien presset med flytende lim på en fiberplate, og sistnevnte ble brukt til å kle innsiden på kjøkkenskuffer og -skap. The added amount was 25 g/m 2 . As in example 1, the foil was pressed with liquid glue onto a fibreboard, and the latter was used to line the inside of kitchen drawers and cupboards.
Eksempel 3 Example 3
Et papir av omtrent 12 0 g/m 2 av bleket sulfatcellulose ble impregnert med 40 g/m 2 av ureaharpiks ved midten av tørkeseksjonen i en papirmaskin ved hjelp av en innskutt bestrykningspresse. Ureaharpiksen som ble anvendt var "Kaurit R 210" (en væskeformet kondensasjonsharpiks av melamin-formaldehyd fra BASF, Forbundsrepublikken Tyskland). A paper of about 120 g/m 2 of bleached sulfate cellulose was impregnated with 40 g/m 2 of urea resin at the center of the drying section of a paper machine by means of an inset coating press. The urea resin used was "Kaurit R 210" (a liquid condensation resin of melamine-formaldehyde from BASF, Federal Republic of Germany).
Et tørket prøvestykke som ble tatt nedstrøms for be-strykningspressen viste en porøsitet på 50 sek/100 ml. A dried sample taken downstream of the coating press showed a porosity of 50 sec/100 ml.
Etter ytterligere tørking ble papiret bestrøket i en blad-bestrykningsinnretning som var innsatt i papirmaskinen, med 20 g/m 2 av en bestrykningspasta hvori pigmentet var 50 % titandioksyd og 50 % leire og bindemidlet en akrylat-latex dispergert i vann. Sluttfolien ble etter tørking brukt på lignende måte som i eksempel 1, som indre belegg i enkle reoler og garderobeskap. After further drying, the paper was coated in a sheet coating device inserted in the paper machine, with 20 g/m 2 of a coating paste in which the pigment was 50% titanium dioxide and 50% clay and the binder an acrylate latex dispersed in water. After drying, the final foil was used in a similar way as in example 1, as an inner coating in simple shelving and wardrobes.
Lignende resultater oppnås både når det bennyttes ubleket sulfatmasse for fremstilling av grunnfolien og når det anvendes bleket eller ubleket sulfitmasse. Similar results are obtained both when unbleached sulphate pulp is used for the production of the base foil and when bleached or unbleached sulphite pulp is used.
