Problems solved by technology

[0003] However, since vinyl chloride resin contains a plasticizer, there is a problem that the surface of the wallpaper will be stained when the plasticizer dissolves over time, or hydrogen chloride gas will be generated in a fire or when it is burned as waste. Toxic gas and black smoke etc.
[0005] However, the paper or pulp non-woven fabric used as a raw material for paper wallpaper has a high density and forms a stiff and inflexible wallpaper, so there are problems that it lacks softness, is not easy to paste, and cannot increase the depth of embossing, and the three-dimensional effect is poor.
[0009] However, in this wallpaper, in the production stage of the wallpaper laminate before the heat embossing process, the bonding of the pulp fiber nonwoven fabric layer and the backing paper layer is carried out by heating and pressing through a hot-melt resin lamination layer. , and the bonding between the pulp fiber non-woven fabric and the surface protective film layer is also carried out by pressing and bonding with an emulsion adhesive, so due to the pressure and water intrusion in the interlayer bonding process, it is impossible to avoid the pulp Decrease in bulkiness of fiber nonwoven layer

Embodiment approach 1

[0048] Below, refer to figure 1 Embodiment 1 of the present invention will be described.

[0049] The wallpaper 10 of the present invention has the following laminated structure: the thermoplastic resin film layer 20 is laminated and bonded on one side of the bulky non-woven fabric layer 3 by a hot-melt method; A polyolefin laminate base paper layer 4 having an extrusion laminated layer of a fusion-bonding polyolefin resin on one side, the extrusion laminated layer being on the inner side (nonwoven fabric layer side), is laminated and bonded by a hot melt method. The other surface of the non-woven fabric layer 3 is connected, and then heat embossing is performed from the side of the thermoplastic resin film layer.

[0050] The non-woven fabric 3 used in the wallpaper 10 of the present invention is not particularly limited, as long as it has softness, flexibility, non-hygroscopicity and bulkiness, it can adopt spunbonded (spunbonded) fabric, jet spray net (spunlace) : Spunlac...

Embodiment 1

[0073] Pulp fibers (NBKP: manufactured by Oji Paper Co., Ltd.) with a fiber length of 0.05 to 5 mm are scattered from a pulp mat forming machine, and the weight per unit area is 45 g / m 2 A layered pad, spray a kind of adhesive aqueous solution, and its composition is: acrylic adhesive (trade name " QET1003 " Japan Zeon company (ZEON Corp.) make) 29.8 mass parts and waterproofing agent (trade name " Asahi Guard" (manufactured by Asahi Glass Co., Ltd.) 0.2 mass part, and the bulk density is 0.075g / cm 3 Air-laid non-woven fabric made of pulp fiber with a thickness of 1.0mm.

[0074] In addition, the polyethylene resin film ("WS-21N" produced by Fusuke Kogyo Co., Ltd., manufactured by Fusuke Kogyo Co., Ltd., the thickness before matting treatment) 21μm, the thickness after matte treatment is 38μm, and the weight per unit area is 19.5g / m 2 ) on the back of the corona discharge treatment, gravure printing was carried out to make a film for the surface layer.

[0075] In addition,...

Embodiment 2

[0079] A polyethylene resin film (" WS-21N" manufactured by Fukusuke Kogyo Co., Ltd., thickness before matting treatment is 21 μm, thickness after matting treatment is 38 μm, weight per unit area is 19.6 g / m 2 ) after corona discharge treatment on the back, gravure printing was carried out to make a film for the surface layer. Moreover, the wallpaper containing the pulp fiber nonwoven fabric was produced by the method similar to Example 1.

Abstract

A wallpaper having a laminated structure comprising a mat finishing film layer formed of a thermoplastic resin film or a front nonwoven fabric layer with printability, stacked thereon a water-repellent pulp fibrous nonwoven fabric layer having a bulk density of 0.05 to 0.3 g / cm<3>, stacked thereon a polyolefin-laminated backing paper layer, wherein the adhesion of each layer is accomplished by a hot-melt bonding, characterized in that said mat finishing film layer or said front nonwoven fabric layer has a concave-convex pattern formed by applying heat-embossing treatment to said mat finishing film layer side or said front nonwoven fabric layer side is provided.

Description

technical field [0001] The present invention relates to a decorative wallpaper that is pasted on walls and ceilings for interior decoration, and particularly relates to a wallpaper that has good processability and ease of construction, does not produce environmental hormone substances, has weather resistance and can maintain aesthetics for a long time wallpaper. Background technique [0002] Coating foamed vinyl chloride resin slurry on the backing paper, heating the coated film to make it foam, and producing foam embossed vinyl chloride wallpaper with embossed patterns, which has the advantages of low price, softness and flexibility. Sex and has a three-dimensional effect, in addition, its coating film has moisture resistance. Therefore, the water of the construction paste applied during construction evaporates very little through the wallpaper, and it is easy to carry out construction, etc., and has been widely used. [0003] However, since vinyl chloride resin contains ...
