2. Description of the Related Art Today, vinyl chloride resin (PVC), acrylic resin, and olefin resin as wallpaper materials are relatively inexpensive and have processability, chemical resistance, electrical insulation, transparency, and weather resistance. It is widely used because of its excellent properties. These resin materials are coated on one side surface of a base paper called backing paper to form a wallpaper.

However, this type of resin-coated wallpaper is used for wall surfaces of houses made of wall materials such as gypsum board.
It is generally adhered using an appropriate adhesive. That is, in today's houses and houses, gypsum board is widely used as a finishing material for walls and ceilings because it has excellent characteristics in fireproofness, soundproofing insulation and heat insulation.

[0004]

However, when the pasted state of the above-mentioned conventional wallpaper is observed in detail, it is as shown in FIG. That is, FIG.
In the above, the gypsum board 10 to which the wallpaper is attached is usually coated with the coated papers 12 and 12 on its surface to maintain its durability. Therefore, the wallpaper 20 made of the resin material 16 coated with the backing paper 14 is appropriately attached to the backing paper 14 with the adhesive 18
Is used to stick the gypsum board 10 onto the coated paper 12 surface.

However, the wallpaper 2 attached in this way
0 is peeled from the wall surface of the gypsum board 10 to replace it, the wallpaper 20 is the adhesive 18 portion, and the backing paper 14 of the wallpaper 20 and the coated paper 12 of the gypsum board 10 do not separate well, For example, as shown in FIG. 7, the wallpaper 20 is often peeled off integrally with the coated paper 12 of the gypsum board 10 or a part of the gypsum board 10.

The cause of this is that when the wallpaper 20 and the gypsum board 10 are adhered, the components of the resin material 16 of the wallpaper 20 penetrate the backing paper 14 and chemically react with the adhesive, so that the coated paper of the gypsum board 10 is covered. It is considered that the adhesive stuck to 12 is peeled off together.

Thus, the coated paper 12 of the gypsum board 10
If there is a loss, not only will it become difficult to attach new wallpaper, but the durability of the gypsum board 10 will be impaired. Also, when disposing of the recovered old wallpaper, it is difficult to incinerate or recycle it because it is mixed with resin material, paper material, adhesive, and gypsum board, and it needs to be handled as harmful industrial waste. Etc. have many problems.

It is characterized in that it is composed of paper that is laminated or laminated.

Further, the wallpaper may be provided with an inorganic paint containing a special binder or another delamination material between the backing paper and the resin material.

In this case, a vinyl chloride resin, an acrylic resin, an olefin resin or the like is preferably used as the resin material for coating the backing paper.

The wallpaper thus constructed can be reused by sticking it to one side of the backing paper with an adhesive on a paper covered with a wall material such as a gypsum board for use.

That is, the reusable wallpaper stuck on a coated paper of a wall material such as a gypsum board is peeled off at the part where the backing paper is laminated or stuck, and the peeled backing paper is made of a resin material. By immersing in the alkaline aqueous solution, the backing paper and the resin material can be clearly separated and recovered.

In this case, the recovered backing paper can be remelted and recycled to be used as recycled paper, or the recovered backing paper can be incinerated and converted into heat energy and used as heat energy. . Further, the recovered resin material can be regenerated after melting to remove impurities.

[0015]

According to the wallpaper according to the present invention, in the wallpaper formed by coating the backing paper with a resin material such as vinyl chloride resin, acrylic resin or olefin resin,
The backing paper is composed of paper laminated or laminated in at least two layers, so that when the backing paper is attached to one side surface of the backing paper with an adhesive on a coated paper for wall material such as gypsum board, the backing paper is It can be smoothly peeled off at the part where the paper is laminated or bonded. Moreover, the wallpaper thus peeled off is soaked in an alkaline aqueous solution such as an aqueous solution of sodium hydroxide, so that the backing paper and the resin material can be clearly separated, and an effective regenerating treatment can be applied to each.
