DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated film capable of performing thermal lamination at low temperatures and having an antifouling function which can be easily embossed, and a wallpaper or decorative board having the laminated film.

[0002]

2. Description of the Related Art Heretofore, there has been known a wallpaper containing a polyvinyl chloride resin layer. However, wallpaper containing these polyvinyl chloride resin layers, decorative panels used for ceiling materials, wall materials, floor materials, etc. of general households, hospitals, clinics, restaurants, factories, ships, trains, automobiles, etc. (hereinafter collectively referred to as wallpaper) Is easily contaminated with tobacco smoke, scale, graffiti, and pigments in various foods. Also, a plasticizer for the polyvinyl chloride resin bleeds on the surface of the wallpaper. Dust adheres to the bleeding plasticizer, and the PVC wallpaper becomes more easily soiled.

As shown in Japanese Patent Application Laid-Open No. 58-23973, a stain-resistant wallpaper in which an acrylic resin film is laminated on a PVC wallpaper is known. However, although these wallpapers have excellent stain resistance compared to non-laminated PVC wallpaper, they are not perfect, and there is a problem that the tendency becomes large especially when a long period of time has passed after lamination. Further, the acrylic resin film is inferior in chemical resistance and particularly easily susceptible to esters, ketones, aromatic compounds, and the like. Therefore, it is necessary to pay attention to dirt wiping, which is not satisfactory.

As disclosed in Japanese Utility Model Application Laid-Open No. 59-172797, a stain-resistant wallpaper obtained by laminating a saponified ethylene-fatty acid vinyl copolymer (hereinafter referred to as EVOH) film on a PVC wallpaper is known. I have. This wallpaper has excellent chemical resistance and plasticizer barrier properties, and is more excellent in stain resistance than non-laminated PVC wallpaper. Further EVO
The H film has an advantage that dust is less likely to adhere to the surface of the wallpaper because the H film has a relatively small electric resistance and is hardly charged with static electricity. However, in the above-mentioned actual application, a urethane-based adhesive is used, and the coating amount is as large as 15 g / m @ 2, which is uneconomical.

[0005] JP-A-60-224542 and JP-A-62-15265 disclose that EVOH is excellent in the barrier property of a plasticizer for polyvinyl chloride resin, and EVOH is a plasticizer for polyvinyl chloride resin. It is described to be used for shutting off of the air. However, the above-mentioned Japanese Patent Application Laid-Open Publication No. Sho-A Sho 59 relates to a solution coating method and a dry lamination method, and does not describe a heat lamination method.

JP-A-60-239233 and JP-A-60-242053 describe a film for thermal lamination of EVOH. However, the film of JP-A-60-239233 uses an expensive isocyanate group-containing reactive polyurethane polymer in the adhesive layer, and the ratio of the isocyanate group-containing reactive polyurethane polymer is 17 to 150% by weight. Parts, it is uneconomical, and does not show sufficient adhesive strength at 120 ° C. or less during thermal lamination, and is processed at a high temperature of 125 ° C. or more even in the examples, and is relatively stiff like a PVC sheet. Although there is no problem with the base material, the operability is poor in the case of lamination with a particularly rigid base material such as foamed PVC wallpaper. on the other hand,
Japanese Patent Application Laid-Open No. 60-242053 is uneconomical because the processing steps are lengthened because the adhesive has two layers.

JP-A-4-131236 discloses a vinyl chloride polymer composition of a laminate comprising a layer of a composition comprising EVOH and a polyolefin and a layer of a composition comprising a vinyl chloride polymer and an isocyanate-urethane compound. It is described that this layer is used for a seal layer and used for an easily-openable container. However, the above-mentioned Japanese Patent Application Laid-Open No. HEI 7 requires easy-openability, that is, a low seal strength, and there is no description about strong lamination such as wallpaper or the like, or a description on development to wallpaper.

In the present invention, the ratio of the vinyl chloride copolymer to CN is 0.01 to 15 parts by weight, more preferably 0.1 to 1 part by weight, per 100 parts by weight of the vinyl chloride copolymer.
5 parts by weight , preferably 0.5 to 10 parts by weight, more preferably 1 to 5 parts by weight. If the content of CN is less than 0.01 part by weight, the adhesion to the EVOH composition film may be insufficient, and if the content exceeds 15 parts by weight, the obtained laminated film may be blocked during storage, and the embossability deteriorates. In addition, the adhesive does not show sufficient adhesive strength at a temperature of 120 ° C. or less during thermal lamination.

Methyl ethyl ketone, methyl butyl Examples thereof include ketone, acetone, ethyl acetate, butyl acetate, benzene, toluene, hexane, and tetrahydrofuran, and one or more mixed solvents of these can be used.

The vinyl chloride copolymer composition contains an antioxidant, a slip agent, a coloring agent, an antibacterial agent, a deodorant, an ultraviolet absorber, a lubricant, polyurethane, polyester, An adhesive for dry lamination or extrusion lamination such as polyether may be blended.

In the present invention, the thickness of the vinyl chloride copolymer composition layer is not particularly limited, but is preferably from 0.5 to 0.5.
It is 10 μm, more preferably 1 to 6 μm, and still more preferably 1 to 4 μm. If the thickness is less than 0.5 μm, the adhesive strength between the EVOH layer or the EVOH composition layer and the polyvinyl chloride resin layer containing the plasticizer tends to be low, and if it exceeds 10 μm, the cost increases, which is not preferable.

In the present invention, by using a resin composition in which a carboxylic acid-modified polyethylene resin (hereinafter abbreviated as CPE) is mixed with EVOH, the adhesive force between the composition layer and the vinyl chloride copolymer composition layer is obtained. Not only is improved, but also embossing becomes easier when laminating with wallpaper or the like. By using the composition layer, the surface gloss of at least one surface of the composition layer (Murakami gloss meter, measured at an incident light angle of 75 °) can be made to be matte of 40% or less. It is possible to obtain a PVC wallpaper excellent in erasing and to give a high-grade feeling. The proportions of EVOH and CPE are as follows: 95-50% by weight of EVOH, 5-50% by weight of CPE, preferably 92-55% by weight of EVOH, CPE8

If the CPE content exceeds 50% by weight, the plasticizer barrier properties are poor, the film-forming properties are poor, and the film has defects such as holes. Furthermore, a melt index (hereinafter referred to as MI) of EVOH and CPE measured at 190 ° C. under a load of 2.16 kg according to ASTM D1238.
Where MIa and MIb, respectively, 3 ≦ MIa / MIb ≦
When it is in the range of 80, a good matte layer is obtained. 19
If MI cannot be measured at 0 ° C., extrapolation is required.

Here, CPE is a polyethylene resin modified with α, β-unsaturated carboxylic acid or the carboxylic anhydride or carboxylic acid ester.
-The content of unsaturated carboxylic acid or said carboxylic anhydride or carboxylic acid ester is 0.0005 to 5 mol%, preferably 0.001 to 1 mol%, more preferably 0.05 mol%;
01 to 0.4 mol%. If it is less than 0.0005 mol%, the dispersibility becomes poor when blended with EVOH, and the matting effect of the film is poor. If it exceeds 5 mol%, the viscosity increases greatly during the blending operation, and the film-forming properties deteriorate. It is desirable that all polyethylene resins are modified with α, β-unsaturated carboxylic acid or the carboxylic anhydride or carboxylic acid ester. And the final modification amount may be within the above range. α, β-unsaturated carboxylic acid or the carboxylic anhydride or carboxylic acid ester includes acrylic acid, methacrylic acid, maleic acid, itaconic acid, maleic anhydride, itaconic anhydride, acrylate ester, methacrylic ester, maleic ester Examples include acid mono- or diesters, itaconic acid mono- or diesters, and maleic anhydride is preferred.

If the ethylene content is less than 20 mol%, the water resistance is poor, and the embossability deteriorates. If it exceeds 65 mol%, the oil resistance will be poor, and oily contaminants will easily penetrate, and the stain resistance will be poor, which is not preferable. Even if the saponification degree of the fatty acid vinyl component is less than 90 mol%, the oil resistance becomes poor, and oily contaminants easily penetrate, and the stain resistance is also poor, which is not preferable. Examples of the fatty acid vinyl used as a raw material for EVOH include vinyl acetate, vinyl pivalate, and vinyl benzoate.
Vinyl acetate is preferred. This EVOH has propylene,
Comonomer components other than ethylene and fatty acid vinyl, such as N-vinylpyrrolidone, can be used as long as the object of the present invention is not hindered.

Slip agent, coloring agent, antibacterial agent, deodorant, ultraviolet absorber,
A thermoplastic resin such as a lubricant or polyamide may be blended.

In the present invention, as a method for obtaining a resin composition comprising EVOH and CPE, a melt-blended pellet is formed in advance using a twin screw extruder, a Brabender plastograph or the like, and then a T-die method or an inflation method. There is a method of forming a film by a melt extrusion method, or a method of directly forming a dry blend pellet into a film by a melt extrusion method such as a T-die method or an inflation method.

In the present invention, an EVOH layer or an EV
The thickness of the resin composition layer of OH and CPE is not particularly limited, but is preferably from 10 to 30 μm, and if it is less than 10 μm, pinholes are easily generated in the film layer at the time of embossing, and plasticity for polyvinyl chloride resin is high. The barrier properties of the agent deteriorate. If the thickness exceeds 30 μm, the laminated wallpaper becomes hard and the work during construction becomes difficult, which is not preferable.

In the present invention, the method for producing the laminated film is not particularly limited, but a method of coating a film of a resin composition of EVOH and CPE with a solution of a vinyl chloride copolymer composition is preferred. It is important to strengthen the adhesive strength between the film made of the resin composition and the vinyl chloride-based copolymer composition layer, and when laminating the vinyl chloride-based copolymer composition on the film made of the resin composition, isocyanate is used. It is necessary that the groups remain, but it is necessary that the isocyanate groups have reacted and disappeared during thermal lamination with vinyl chloride wallpaper or the like. The method for eliminating the isocyanate group is such that 25 to 45
Achieved by storing at a temperature of ° C. for at least 16 hours.

In the present invention, a wallpaper containing a polyvinyl chloride resin layer containing a plasticizer is defined as a support made of flame-retardant paper, non-woven fabric, glass fiber, asbestos paper, or the like. Agents, if necessary, pigments, fillers, stabilizers, etc., are layered by calendering, coating, etc., and printed on these laminates, or foamed By blending an agent, a product obtained by foaming a polyvinyl chloride resin 1.5 to 15 times in the final product can be used. In the present invention, the decorative board is a generic term for a printed decorative board, a decorative plaster board, a PVC decorative board, a PVC steel sheet, a PVC noncombustible board, and the like. The printed decorative board is a product obtained by printing on thin paper or the like and laminating it on a support made of plywood, particle board, or the like. Also, embossing may be applied to emphasize the three-dimensional effect. Also plasterboard,
PVC decorative board, PVC steel plate, PVC noncombustible plate, etc. are printed on a sheet made of polyvinyl chloride resin containing plasticizer etc., and this is supported by gypsum board, particle board, plywood, steel plate, concrete plate etc. It is a thing laminated on the body. As in the case of a printed decorative board, embossing may be applied to enhance the three-dimensional effect.

In the present invention, the plasticizer for the polyvinyl chloride resin is liquid at 20 ° C.
It contains 5% by weight. Examples of the plasticizer which is liquid at 20 ° C. include dibutyl phthalate, di-2-ethylhexyl phthalate, diisooctyl phthalate, diisodecyl phthalate,
Phthalate plasticizers such as didecyl phthalate, dinonyl phthalate, butyl lauryl phthalate, dilauryl phthalate, and butyl benzyl phthalate; phosphate esters such as tricresyl phosphate, tributyl phosphate, and tri-2-ethylhexyl phosphate And a chlorine-containing plasticizer such as chlorinated paraffin. By laminating the layer of the composition of the present invention on at least one surface, particularly the outermost layer, of the polyvinyl chloride resin layer containing one or more of these plasticizers, the desired laminate can be obtained.

In the present invention, the temperature of the thermal lamination of the laminated film and the PVC wallpaper is preferably from 70 to 180.
° C, more preferably 80 to 160 ° C, still more preferably 100 to 150 ° C. If the temperature is lower than 70 ° C., it may be difficult to develop the adhesive strength, and it may be difficult to perform embossing for enhancing the three-dimensional effect. If the temperature exceeds 180 ° C., not only may the resin composition layer on the outer surface of the laminated film partially melt and become sticky, or the glossiness may be deteriorated, but also the foamed PVC layer may be subjected to pressure during heat lamination. Compressed, resulting in poor emboss reproducibility.

The laminate of the present invention thus obtained is
Thermal lamination at low temperature is possible, embossing is easy, there is no change in laminating strength even after long-term use, and further, the stain-preventing function is maintained, and it is very useful as a wallpaper or decorative board.

Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited thereto.

A vinyl chloride copolymer composition comprising 100 parts by weight of a vinyl chloride copolymer containing 87 mol% of a vinyl chloride component and 13 mol% of a vinyl acetate component and 1.5 parts by weight of hexamethylene diisocyanate was prepared by adding methyl ethyl ketone :
Immediately after dissolving in a mixed solvent of toluene = 1: 1 so as to have a solid content concentration of 20% by weight, the film was coated using a gravure coater so that the coating amount was 2 g / mｇ2 (solid content basis). After drying at 70 ° C. for 4 minutes, a laminated film was obtained. The laminated film was stored in a roll at 35 ° C. for 2 days to eliminate isocyanate groups. No blocking occurred during storage at 35 ° C.
