Abstract

(57) [Summary] [Purpose] It can be reliably applied to walls that do not absorb water such as concrete walls and rough walls such as sand and earth walls. [Structure] A water-absorbent paper 1 is adhered to one surface of an adhesive layer 2 in which a relatively elastic base cloth 2a such as a non-woven fabric is impregnated with a hard-to-dry adhesive 2b such as a rubber adhesive. The release paper 3 is adhered to the other surface.

[Industrial applications]

 The present invention relates to a wallpaper-applying underlay for reliably attaching wallpaper to a wall surface on a rough wall surface such as a sand wall or a soil wall.

[0002]

[Prior art]

 Conventionally, in order to attach the wallpaper to the wall surface, it is necessary to apply glue to the back surface of the wallpaper, but it is difficult for an unskilled person to glue the back surface of the wallpaper evenly, and the finish is not good. There was such a problem.

Therefore, as a solution to the above-mentioned problems, for example, an adhesive in a non-dried state (a starch paste) containing moisture on the back surface of a wallpaper as disclosed in Japanese Utility Model Publication No. 1-21960. ) Has been applied, and a release film has been attached to the adhesive surface.

[0004] With this wallpaper, the peeling film can be peeled off when it is attached to the wall surface, and the adhesive surface can be attached to the wall surface so that it can be attached neatly by an amateur and can be attached neatly. It has the advantage that

[0005]

[Problems to be solved by the device]

 However, the above-mentioned undried paste containing water (starch paste) does not have water absorption properties such as a rough surface such as a sand wall or a soil wall or a concrete wall. If there is no wall surface, it is difficult to attach it, and even if it is attached, it is easy to peel off.

The present invention is intended to solve the above-mentioned problems, and its purpose is to provide a wall surface that does not absorb water such as a concrete wall and a rough wall surface such as a sand wall or a soil wall. It is said that the company will provide a subbed for wallpaper that can be reliably applied.

[0007]

[Means for Solving the Problems]

 The wallpaper of the present invention is intended to achieve the above-mentioned object. The means is to absorb water on one surface of an adhesive layer obtained by impregnating a relatively elastic base fabric such as a non-woven fabric with a non-drying glue such as rubber glue. And a release paper adhered to the other surface of the adhesive layer.The water-absorbent paper is made into Japanese paper, and the overall shape is tape-like or sheet-like. It is characterized by being formed.

[0008]

[Action]

 When the release paper is peeled off from the adhesive surface and adhered to the wall surface, the wallpapering subbing of the present invention configured as described above has a rough adhesive surface due to the elastic force of the non-woven fabric or the like even if the wall surface is rough. It adheres strongly according to the unevenness of the surface without creating a gap, and it adheres even to walls that do not absorb water, such as concrete walls.

Since water-absorptive paper is pasted on the front surface of the bonded adhesive layer, the wallpaper is firmly adhered by pasting the wallpaper onto the paper, and therefore the glue is applied beforehand. It is easy to attach the wallpaper to the wall.

[0010]

【Example】

 Hereinafter, an embodiment using a wallpaper-applying subbing according to the present invention will be described with reference to the drawings. In FIG. 1, 1 is a water absorbent paper, for example, water absorbent paper such as Japanese paper, 2 is a relatively elastic base cloth 2a such as a non-woven fabric impregnated with rubber glue 2b or the like, which is hard to dry. This is an adhesive layer, and the rubber glue 2b oozes out on both sides of the base fabric 2a. 3 is a release paper.

Then, the paper 1 having the water absorbing property is attached to one surface of the adhesive layer 2 described above, and the release paper is attached to the other surface to form the undercoat A. The planar shape of the underlay A is a tape shape or a sheet shape. At the time of sale, the tape shape is rolled and a sheet shape is rolled into a plate or roll for sale.

[0012] be described a case where de Npun glue C ₁ to affix the coated wallpaper C on the wall surface B of the rough surface of the sand wall or the like by utilizing the thus constituted wallpaper sticking subfloor A 2, together with FIG. 3 . The wall surface B shown in FIG. 2 is surrounded by a pillar B ₁ and a kamoi B ₂ and is of a size such that two pieces of wallpaper C are attached to the wall surface B, and a tape-like material is used as the underlayment A. Suppose you used it.

First, the release paper 3 on the subbing A is peeled off from the adhesive layer 2, and as shown in FIG. 2, four rubber tapes 2b are peeled off from the release paper 3 in the vertical direction and six in the horizontal direction. At this time, even if the wall surface B is a rough surface such as a sand wall, due to the elasticity of the base cloth 2a, it is strongly bonded along the irregularities of the rough surface. Further, even if the wall surface B is a water-absorbing wall surface such as a concrete wall, since it is the rubber paste 2b, it is bonded with a strong adhesive force.

Next, the starch paste C ₁ of the wallpaper C is adhered to the water-absorbent Japanese paper or the like of the underlaying A that is adhesively fixed to the wall surface B, so that the water content of the starch paste C ₁ is changed to paper. 1, the wallpaper C is strongly adhered to the wall surface B through the underlayment A (see FIG. 3). In addition, by applying putty to the portion of the wall surface B to which the subbing A is not adhered in FIG. 2, it is possible to attach the wallpaper C neatly without unevenness.

[0015]

[Effect of device]

 As described above, according to the present invention, when the release paper is peeled off from the adhesive surface and adhered to the wall surface, even if the wall surface is rough, the adhesive force is strong along the unevenness of the rough surface due to the elastic force of the base cloth such as nonwoven fabric. Since it is glued to the wall, it can be easily attached to the wall surface by pasting a wallpaper to which glue has been applied in advance, and a wall that does not absorb water such as a concrete wall. Also has the effect that it can be attached via the underlayment.
