Description
Oppfinnelsen vedrører et papir for tapeter og plakater, som etter påklebning på en mur eller en annen vegg lett kan trekkes av som helhet fra veggen. The invention relates to a paper for wallpaper and posters, which, after sticking to a wall or other wall, can be easily pulled off as a whole from the wall.
Ofte er det nyttig og nødvendig å fjerne et med vann-oppløselig klebestoff påklebet bladformet materiale av papir, eksempelvis en opplimt tapet eller en plakat etter dager, uker eller år fra den påklebede flate. Som bekjent er dette arbeidet vanskelig, tidsrøvende og smussforårsakende. Normalt fuktes papiret som skal fjernes og tas etter noen tid med en malespatel eller lignende apparat fra undergrunnen. Derved blir gulv og klær, spesielt også teppegulv ofte sterkt forurenset. Denne arbeids-måte er dessuten ikke mulig når det påklebede, bladformede materiale er appretert vannavstøtende. Idag er imidlertid tapetene ofte appretert vaskbare eller 100% vaskbare. Av disse grunner har det i lengere tid bestått ønske om en tapet og også en plakat, It is often useful and necessary to remove a leaf-shaped material of paper that has been stuck on with a water-soluble adhesive, for example a glued-on wallpaper or a poster, after days, weeks or years from the stuck-on surface. As you know, this work is difficult, time-consuming and causes dirt. Normally, the paper to be removed is moistened and taken after some time with a paint spatula or similar device from the underground. As a result, floors and clothes, especially carpeted floors, are often heavily contaminated. This method of working is also not possible when the glued, leaf-shaped material has been prepared water-repellent. Today, however, the wallpapers are often washable or 100% washable. For these reasons, there has been a desire for a wallpaper and also a poster for a long time,
som på enkel måte fullstendig lar seg trekke av fra den påklebede vegg eller andre beklebede flater, også når de ikke er gjennom-fuktet med vann. which can easily be completely removed from the glued wall or other coated surfaces, even when they are not soaked through with water.
Det er kjent på en vegg som skal tapetseres å klebe It is known on a wall to be wallpapered to stick
en undertapet, som består av papir, som på en side er appretert klebestoffavvisende eller å beklebe veggen med skumstoffbaner av polystyren. I begge tilfeller oppnås at den påklebede tapet senere ved behov kan fjernes fra veggen uten vanskeligheter. Disse fremgangsmåter har den ulempe at det i tillegg til den egentlige tapetsering er forbundet en forbehandling av veggen med den. a wallpaper, which consists of paper, which on one side is prepared to repel adhesive or to stick to the wall with foam strips of polystyrene. In both cases, the attached wallpaper can later be removed from the wall without difficulty if necessary. These methods have the disadvantage that, in addition to the actual wallpapering, a pre-treatment of the wall is associated with it.
Dette øker tapetseringsomkostningene. Tilsvarende gjelder for This increases wallpapering costs. The same applies to
den videre kjente fremgangsmåte å innstryke veggen som skal tapetseres med en emulsjon resp. dispersjon som har den egenskap å danne et overtrekk, hvorfra en påklebet tapet senere likeledes kan fjernes lett. Kjent er videre de såkalte spaltbare papir- the further known method of coating the wall to be wallpapered with an emulsion resp. dispersion which has the property of forming a coating, from which an attached wallpaper can later also be easily removed. Also known are the so-called fissile paper
tapeter som består av to (bare løst) på hverandre klebede paplr-sjikt og derfor avtrekning fra veggen spalter seg i to sjikt, således at sjiktet med det påtrykkede tapetmønster fjernes og det andre sjikt blir tilbake på veggen som en type makulatur, hvorpå det igjen kan tapetseres. Denne fremgangsmåte har den ulempe at man enten etter flere gangers tapetsering har flere makulatursjikt på veggen, som en eller annen gang vil måtte fjernes og da er desto vanskeligere å fjerne, eller at man for de tapet-seringer som følger første tapetsering å få ennu ikke spaltende tapeter til disposisjon, hvilket tydeligvis har ulemper. Det er videre kjent på den side av tapeten som er bestemt til påklebning å påføre et sjikt av en emulsjon eller blanding av voks og termoplastisk kunststoff og derved å appretere den hvis det er nødvendig klebestoffavvisende. Ved fremstillingen av disse klebestoff avvisende belegg er imidlertid forholdsvis dyr, spesielt fordi det av en våt papirstoffbane i første rekke må fremstilles ferdig tørt tapetpapir og dette deretter igjen må tørkes etter påføring av emulsjon. wallpaper that consists of two (only loosely) glued paplr layers and therefore when removed from the wall splits into two layers, so that the layer with the printed wallpaper pattern is removed and the second layer is left on the wall as a type of waste paper, after which it again can be wallpapered. This method has the disadvantage that either after several wallpapering you have several layers of waste paper on the wall, which will have to be removed at one time or another and are then all the more difficult to remove, or that for the wallpaperings that follow the first wallpapering you still cannot get splitting wallpaper available, which clearly has disadvantages. It is also known to apply a layer of an emulsion or mixture of wax and thermoplastic plastic to the side of the wallpaper that is intended for sticking, and thereby to prepare it if adhesive repellent is necessary. The production of these adhesive-repellent coatings is, however, relatively expensive, especially because dry wallpaper paper must first be produced from a wet paper fabric web and this must then be dried again after application of emulsion.
Oppfinnelsens oppgave er under unngåelse av de nevnte ulemper å stille et papir til disposisjon for tapeter og plakater, som etter påklebning på en vegg lett igjen kan trekkes av veggen. Ved løsning av oppgaven gåes det ut fra det kjente papir for tapeter og plakater som har en overflate, hvorved det etter påklebning på den mur eller en annen vegg med et klister senere kan løsnes fra klebingen ved lett avrivning og som løsning av oppgaven ble det funnet et papir av nevnte type som er karakterisert ved at det består av to i hverandre sammenfiltrede fibersjikt, hvorav det ene tilsvarer et vanlig tapetråpapir og det andre er et tapetråpapir, hvori 40 til 80 vekt% av alle fibre er polyolefinfibre og fra 0,5-5% referert til vekten av alle fibre er fra en vandig dispersjon utfnokket termoplast. The task of the invention is, while avoiding the aforementioned disadvantages, to make a paper available for wallpaper and posters, which, after sticking to a wall, can easily be pulled off the wall. When solving the task, the starting point is the familiar paper for wallpaper and posters that has a surface, whereby after sticking to the wall or another wall with an adhesive, it can later be detached from the sticking by easy tearing off and as a solution to the task it was found a paper of the aforementioned type, which is characterized by the fact that it consists of two interwoven fiber layers, one of which corresponds to a normal wallpaper raw paper and the other is a wallpaper raw paper, in which 40 to 80% by weight of all fibers are polyolefin fibers and from 0.5- 5% referred to the weight of all fibers is from an aqueous dispersion denatured thermoplastic.
Til forskjell fra såkalte spaltbare tapeter som likeledes består av to fibersjikt er papirets to fibersjikt ifølge oppfinnelsen sammenfiltret i hverandre. Papiret fremstilles altså i en papirmaskin, hvor man fremstiller to stoffbaner separat for seg og etter bladdannelses- og avvanningsprosessen kan forbinde med hverandre ved rysting (Gautschen). In contrast to so-called splittable wallpaper, which likewise consists of two fiber layers, the paper's two fiber layers according to the invention are tangled in each other. The paper is therefore produced in a paper machine, where two webs of fabric are produced separately and after the sheet formation and dewatering process can be connected to each other by shaking (Gautschen).
Fortrinnsvis anvender man til fremstilling av papiret en Inverform-papirmaskin. De spesielle trekk ved denne maskintype består i anvendelse av en langwire med så mange stoffoppløs på banens løperetning anordnet etter hverandre, som kartongen som skal fremstilles ha lag. Derved kan de enkelte stoffsammenset-ninger påføres i ønskelig rekkefølge. Fortrinnsvis påføres det klebestoffavvisende sjikt på det allerede på langwiren påførte andre sjikt. An Inverform paper machine is preferably used to produce the paper. The special features of this type of machine consist in the use of a long wire with as many layers of material dissolved in the running direction of the web arranged one after the other, as the cardboard to be produced has layers. Thereby, the individual material compositions can be applied in the desired order. Preferably, the adhesive-repellent layer is applied to the second layer already applied to the long wire.
Det ene fibersjikt av papiret ifølge oppfinnelsen tilsvarer i sin sammensetning et vanlig tapetråpapir, inneholder altså treslip og/eller cellulosefibre, limingsmiddel og eventuelt fyllstoff i de vanlige mengdeforhold, slik det eksempelvis er fastlagt ifølge DIN-blad 6730. Det andre sjikt er prinsipielt likeledes sammensatt, avviker imidlertid spesielt med hensyn til type anvendt fibre og dessuten også ved nærvær av en forholdsvis liten mengde utfnokket termoplastisk natur- og kunststoffmengder fra det vanlige. One fiber layer of the paper according to the invention corresponds in its composition to ordinary wallpaper raw paper, i.e. contains wood shavings and/or cellulose fibres, adhesive and possibly filler in the usual proportions, as for example determined according to DIN sheet 6730. The second layer is composed in principle in the same way , however, deviates from the norm in particular with regard to the type of fibers used and also in the presence of a relatively small amount of natural and synthetic thermoplastic.
Av de i det uvanlige sjikt inneholdte fibre består 40-80 vekt%, fortrinnsvis ca. 60 vekt% av polyolefinfibre og 20-60 vekt%, fortrinnsvis ca. 40 vekt% av cellulosefibre. Som polyolefinfibre kommer det spesielt slike i betraktning av polyetylen eller polypropylen. Polyolefinfibre lar seg fremstille etter fremgangsmåtene som er omtalt i DOS 1.951.576 og 2.117.370. Fortrinnsvis anvendes de ifølge fremgangsmåten i DOS 2.117.370 frem-stilte polyetylen- eller polypropylenfibre som utmerker seg ved at de har meget stor overflate, nemlig på mer enn 1 m /g, fordi de gir et spesielt fast, sammenfiltret papirlag. Den meget for-delaktige masse av polyolefinfibre, hvorfra det kan fremstilles en tilstrekkelig stabil suspensjon av fibre er omtalt i DOS 2.208.555. De der omtalte masser anvendes fortrinnsvis til fremstilling av det polyolefinfiberholdige sjikt av papiret ifølge oppfinnelsen. Of the fibers contained in the unusual layer, 40-80% by weight, preferably approx. 60% by weight of polyolefin fibers and 20-60% by weight, preferably approx. 40% by weight of cellulose fibres. As polyolefin fibres, polyethylene or polypropylene in particular come into consideration. Polyolefin fibers can be produced according to the methods described in DOS 1,951,576 and 2,117,370. Polyethylene or polypropylene fibers produced according to the method in DOS 2,117,370 are preferably used, which are distinguished by having a very large surface area, namely of more than 1 m/g, because they produce a particularly firm, tangled paper layer. The very advantageous mass of polyolefin fibers from which a sufficiently stable suspension of fibers can be produced is described in DOS 2,208,555. The pulps mentioned there are preferably used for the production of the polyolefin fiber-containing layer of the paper according to the invention.
De i det polyolefinholdige sjikt tilstedeværende fra dispersjonen utfnokkede termoplastiske kunst- eller naturstoffer er utfnokket av emulgatorfrie naturlige eller kunstige latekser, eksempelvis på basis av butadien-styren-kopolymerisater, kautsjuk, polykloropren eller butadien-polyakrylnitril-kopolymerisater. Spesielt fordelaktig er anvendelsen av en emulgatorfri dispersjon av et kopolymerisat av etylen og alkalisaltet av en enkelt umettet acylamid-N-sulfonsyre. Det dreier seg om alkalisalter med formel R<1>CH=C(R<2>)CONMe-S03Me, hvori R<1> og R<2> betyr hydrogen eller en organisk rest med 1 til 10 C-atomer og Me betyr et alkalimetall, spesielt K. Fremstillingen av slike kopolymerisater av etylen er omtalt i DOS 1.72 0.66 7. Fortrinnsvis anvendes dispersjoner, hvis fremstilling er omtalt i Eks. 9 i dette DOS. The thermoplastic synthetic or natural materials present in the polyolefin-containing layer from the dispersion are defoamed from emulsifier-free natural or artificial latexes, for example on the basis of butadiene-styrene copolymers, rubber, polychloroprene or butadiene-polyacrylonitrile copolymers. Particularly advantageous is the use of an emulsifier-free dispersion of a copolymer of ethylene and the alkali salt of a single unsaturated acylamide-N-sulfonic acid. These are alkali salts with the formula R<1>CH=C(R<2>)CONMe-SO3Me, where R<1> and R<2> mean hydrogen or an organic residue with 1 to 10 C atoms and Me means an alkali metal, especially K. The production of such copolymers of ethylene is discussed in DOS 1.72 0.66 7. Dispersions are preferably used, the production of which is discussed in Ex. 9 in this DOS.
Tilsetningen av dispersjonen av termoplastiske par-tikler til papirgrøten og utfnokning av partiklene foregår hen-siktsmessig først etter cellulosens maling og etter sammenblan-ding av den malte cellulose med polyolefinfiber-suspensjonen. The addition of the dispersion of thermoplastic particles to the paper pulp and deflocculation of the particles takes place expediently only after the cellulose has been milled and after the milled cellulose has been mixed with the polyolefin fiber suspension.
Ved utfnokking, eksempelvis med aluminiumsulfat, blir kopolymeri-satet etter bladdannelse og avvanning av bladet på papirets wire omtrent fullstendig som fnokker finfordelt i papiret. When fluffing, for example with aluminum sulphate, the copolymer after leaf formation and dewatering of the leaf on the wire of the paper is almost completely finely distributed as fluff in the paper.
Flatevekten av papirsjiktet med den vanlige sammensetning retter seg etter den ønskede papirkvalitet. Den utgjør eksempelvis for enkle tapeter ca. 50 til 6 5 g/m^, for bedre tapeter 80 til 100 g/m 2 og for tyngre tapeter over 110 g/m ?. Av omkosthingsgrunner anvender man som fibermateriale for disse sjikt treslip blandet med mer eller mindre cellulosefibre. Der-til kommer de vanlige limmidler. For verdifulle anvendelsesformål kan dette fibersjikt også bestå av helt trefritt, seigt, lang-fibret fibermateriale. Flatevekten av papirsjiktet med den uvanlige sammensetning utgjør for det meste 5 til 100 g/m , fortrinnsvis 5 til 30 g/m 2 . Også o heri kan mengden av fibre som er tilstede foruten mengden av polyolefinfibre ved en mer eller mindre stor del bestå av treslip. The basis weight of the paper layer with the usual composition depends on the desired paper quality. For example, for simple wallpaper, it amounts to approx. 50 to 65 g/m^, for better wallpapers 80 to 100 g/m 2 and for heavier wallpapers over 110 g/m ?. For reasons of cost, layered wood shavings mixed with more or less cellulose fibers are used as fiber material for these. In addition, the usual adhesives are added. For valuable applications, this fiber layer can also consist of completely wood-free, tough, long-fibered fiber material. The basis weight of the paper layer with the unusual composition is mostly 5 to 100 g/m 2 , preferably 5 to 30 g/m 2 . Here, too, the amount of fibers present in addition to the amount of polyolefin fibers may consist to a greater or lesser extent of wood shavings.
Tolagspapiret ifølge oppfinnelsen kan på kjent måte oppklebes med vandig klister på ønsket underlag. Som klister er de anvendbare alle i handelen befinnende produkter, eksempelvis stivelse resp. stivelsesderivater, celluloseetere, polyvinylalkohol og blandinger av disse stoffer. Papiret kan imidlertid også på den side som er dannet av det polyolefinfiberholdige fibersjikt ved en belegning eller bestøvning etter det elektrostatiske prin-sipp en påføring av vannaktiverbare materialer, som fra vannopp-løselige celluloseetere, vannoppløselige eller vannsvellbare stivelsesderivater eller polyvinylalkohol eller en flerkomponent-blanding av de ovennevnte stoffer. En slik påføring skal være 10 til 100 g/m<2>, spesielt 10 til 30 g/m<2> tung. Således fremstilt papir kan klebes uten påføring av klebestoff og krever før sammen-klebning bare en aktivering med vann. The two-layer paper according to the invention can be stuck to the desired substrate in a known manner with aqueous glue. All commercially available products can be used as adhesives, for example starch or starch derivatives, cellulose ethers, polyvinyl alcohol and mixtures of these substances. However, the paper can also, on the side formed by the polyolefin fiber-containing fiber layer by a coating or dusting according to the electrostatic principle, an application of water-activatable materials, such as from water-soluble cellulose ethers, water-soluble or water-swellable starch derivatives or polyvinyl alcohol or a multi-component mixture of the above substances. Such an application should be 10 to 100 g/m<2>, especially 10 to 30 g/m<2> heavy. Paper produced in this way can be glued without the application of adhesive and only requires activation with water before gluing.
