SUMMARY OF THE INVENTION The present invention is a base material applied to a wall surface to form an adhesive base for a wallpaper, and a flexible base sheet which is less suitable for adhesion than wallpaper. The base material sheet is provided with a pressure-sensitive adhesive layer on the back surface of the base material sheet for adhering and fixing the base material sheet to a wall surface.

Further, according to the present invention, after forming a sticking base on a wall surface using the wallpaper sticking base material having the above-mentioned constitution, a wallpaper having a low adhesive strength is applied to the sticking base to stick the wallpaper. The present invention relates to a method for attaching wallpaper, which is characterized in that

[0006]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the base material of the present invention.

As shown in FIG. 1, the base material of the present invention is provided with a base material sheet 1, and the base material sheet 1 is carried into a construction site in a rolled-up state, and further, a corner portion of a wall surface and the like. A flexible material is used in order to make it possible to bend and attach the same.

The base sheet 1 is used to form an adhesive base for releasably attaching the wallpaper, and is made of an olefinic material such as polyethylene or polypropylene, which is less suitable for adhesion than plastic materials, especially wallpaper. Molded from resin. The thickness of the base material sheet 1 is not particularly limited as long as it can maintain the strength as a bonding base.
Usually, it is appropriately selected from the range of about 10 ^-5 to 10 ^-2 m.

On the back side of the substrate sheet 1, the substrate sheet 1
A pressure-sensitive adhesive layer 2 is provided for sticking and fixing to the wall surface.

The pressure-sensitive adhesive forming the pressure-sensitive adhesive layer 2 is required to be able to exhibit a relatively large adhesive force to the base sheet 1 and the wall surface, and among the various known pressure-sensitive adhesives, the base sheet 1 and the wall surface. The material is selected in consideration of the material.

For example, when the base sheet 1 is made of olefin resin and the wall surface is made of wood, paperboard, gypsum, polystyrene, polyurethane, etc.,
Acrylic or rubber adhesives are suitable.

The adhesive force of the pressure-sensitive adhesive layer 2 to the base sheet 1 and the wall surface is usually about 0.7 to 2.5 kgf / 25 mm.

When forming the pressure-sensitive adhesive layer 2 from the pressure-sensitive adhesive, a curing agent can be added to the pressure-sensitive adhesive according to a conventional method.

The adhesive layer 2 can be protected by a release paper (not shown) until it is used. When the base material sheet 1 is wound into a roll, one side of the base material sheet 1 can be used as a release paper by subjecting one side of the base material sheet 1 to a release treatment.

FIG. 2 schematically shows one usage situation of the base material of the present invention.

As is clear from FIG. 2, the base material of the present invention is
The adhesive layer 2 on the back side is adhesively fixed to the wall surface 3.
Therefore, the adhesive base made of the base material sheet 1 is formed on the wall surface 3.

When the wallpaper 4 is attached to the surface of the base material sheet 1 forming the attachment base, the adhesive 5 is first applied to the back surface of the wallpaper 4, and then the wallpaper 4 is applied to the wall surface 3. It is attached via the adhesive 5.

The adhesive 5 has a low adhesive strength to the base sheet 1, for example, 0.1 to 0.4 kgf / in order to enable the wallpaper 4 to be peeled from the bonding base, that is, the base sheet bonding interface.
Adhesive strength of about 25 mm is used. By the way, since the wallpaper 4 is superior in adhesiveness to the base material sheet 1 in terms of material, the adhesive force between the adhesive 5 and the wallpaper 4 is larger than the adhesive force between the base material sheet 1.

Then, when the adhesive force between the layers in the adhered state of the wallpaper 4 is examined, the adhesive 5 and the base sheet 1
Since the adhesive force between and is the smallest, the wallpaper 4 can be easily peeled off at the adhesive interface.

As the adhesive 5, various kinds of adhesives such as acrylic type, vinyl acetate type, urethane type emulsion type, solution type, hot melt type and reaction hardening type can be used, but an aqueous emulsion type adhesive is used. It is suitable because it has excellent workability.

For example, as the adhesive 5 applied to the base sheet 1 made of an olefin resin, an aqueous emulsion adhesive having a concentration of about 10 to 70% containing an acrylic adhesive and a starch paste as active ingredients is used. Appropriate.

In this case, if the proportion of starch paste is too large, the adhesive strength to the base sheet 1 will be insufficient, and if it is too small, the adhesive strength will be excessive and the releasability will be reduced. After coating, the time to dry becomes too fast and the workability deteriorates. Therefore, the ratio of starch paste is 5 to 100 parts by weight of the acrylic adhesive.
50 parts by weight (solid ratio), particularly about 10 to 30 parts by weight are suitable.

With the adhesive having the above mixing ratio, the time until drying is not so different from that in the case of starch paste, and pattern matching in the pasted state can be performed without any trouble.

The experimental examples of the present invention will be described below.
