JPH07300800A - Wall paper and method for peeling the same - Google Patents

Abstract

PURPOSE:To obtain readily peelable wall paper and to provide a peeling method. CONSTITUTION:In wall paper useful as a building material, especially an interior material, one side of raw fabric 1 is coated with a decorative layer 2 and the opposite side is precoated with a layer comprising a polymer material and a solid plasticizer or the polymer material, a tackifier and the solid plasticizer as a heat-sensitive peeling layer 3. The wall paper is applied to a wall face with a starch. When the wall paper is peeled, the wall paper is heated from the surface to soften the heatsensitive peel layer 3 and to simply peel the wall paper.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper used as a building material, especially as an interior material, and more particularly to a wallpaper which can be easily peeled off when the wallpaper is reattached by reforming or the like.

[0002]

2. Description of the Related Art Conventional wallpaper is pasted on a wall with starch-based glue, etc., but it is difficult to peel it off when it is re-applied, and it tears between the base paper layers until the next new wallpaper is pasted. In addition, it takes time to clean the wall.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances and provides a wallpaper which can be easily peeled off.

[0004]

The present invention provides a polymeric material, a solid plasticizer or a polymeric material, an adhesion-imparting agent, and a solid plasticizer in advance on the side opposite to the decorative surface of a wallpaper used as a building material, especially an interior material. Is a layer formed by coating as a release layer,
This is applied to the wall surface with starch-based glue or the like. When peeling off the wallpaper, a method of softening the peeling layer to make peeling easy by applying heat from the surface of the wallpaper is also a part of the present invention.

The structure of the present invention will be described with reference to FIG.
The original fabric (1) is provided with a decorative layer (2) provided with wood grain or an abstract pattern, and the heat-sensitive peeling layer (3) is provided on the opposite side.

The base material (1) may be paper, a paper and a plastic film laminated together, or a plastic film.

The basic composition of the heat-sensitive release layer (3) is composed of a polymer material and a solid plasticizer. It is a layer that has no fluidity at room temperature, but softens due to heating, and continues for a considerable period of time after cooling. Here, the polymer material is polyvinyl acetate, copolyethylene-vinyl acetate, polyacrylic acid ester-based, polyvinyl chloride-based, natural rubber, synthetic rubber,
Polymer compounds such as copolyvinyl acetate-acrylic acid ester, polyester-based, polyurethane-based and the like. Solid plasticizers are solid at room temperature and dissolve when heated above their melting point, swell / dissolve polymeric materials, develop fluidity, and do not crystallize easily once dissolved, resulting in thermal activation. The state after conversion can be maintained for a long time.

For example, diphenyl phthalate, dihexyl phthalate, dicyclohexyl phthalate, dihydroabietyl phthalate, dimethyl isophthalate, sucrose benzoate, ethylene glycol dibenzoate, trimethylolethane tribenzoate, tribenzoic acid glyceride, Examples include pentaerythribenzoate, sucrose octaacetate, tricyclohexyl citrate, and N-cyclohexyl-P-toluenesulfonamide.

An adhesion promoter may be added to the heat-sensitive release layer. The adhesion-imparting agent increases the adhesiveness with the original fabric (1),
It is a component that enhances the strength of the adhesive to be stuck on the wall surface, and is a resin such as a rosin derivative, a terpene resin system, a petroleum resin system, a phenol resin system, a xylene resin system.

When this wallpaper is applied to the wall surface with a starch-based adhesive and heat is applied from the surface of the wallpaper, the heat-sensitive release layer becomes soft and the wallpaper is easily peeled off.

[0011]

[Function] When wallpaper is applied to the wall surface with a starch-based adhesive or the like, the wallpaper is coated beforehand with a heat-sensitive release layer consisting of a polymer material, a solid plasticizer or a polymer material, a solid plasticizer, and an adhesion-imparting agent. When peeling off, the heat-sensitive peeling layer is softened by applying heat from the surface, and can be peeled off easily.

【Example】

<Example 1> A sheet having a basis weight of 100 g / m ² was coated with vinyl chloride containing a foaming agent for foaming, and then 30 μm of a heat-sensitive release layer having the composition of (Table 1) was coated on the opposite side of the embossed sheet. Was pasted on the wall surface with starch paste. After the adhered state was stabilized on this pasted wallpaper, the wallpaper was peeled off by heating from the surface with a powerful dryer, and the paper was easily peeled off without tearing.

Example 2 Vinyl chloride containing a foaming agent was applied to a paper having a basis weight of 100 g / m ² to foam it, and a heat-sensitive peeling layer having the composition (Table 2) was formed on the opposite side of the embossed product (Table 2).
The μ-coated product was applied to the wall surface with starch paste. After the adhered state was stabilized on this pasted wallpaper, the wallpaper was peeled off by heating from the surface with a powerful dryer, and the paper was easily peeled off without tearing.
