Description

[Detailed description of the invention] (Industrial application field) When pasting wallpaper on the walls or ceiling of a house, the wallpaper adhesive tape of this invention is used to interpose it between the edge of the wallpaper and the wall surface, and used to strengthen.

(Prior art) When pasting wallpaper on the walls or ceiling of a house, conventionally, starch paste was uniformly applied to the entire back side of a long piece of wallpaper, this was cut to a predetermined length, and then this wallpaper was pasted. Paste it next to the already pasted wallpaper so that it partially overlaps to match the pattern, cut the overlapped part lengthwise with the tip of a knife, then peel off the overlapped part, After the edges separated by the above-mentioned cutting were removed from both pieces of wallpaper, both pieces were again crimped to the wall surface, and the cut edges were stuck together so as to butt each other.

However, in the above method, the glue on the back side of the edge of the upper wallpaper is transferred to the edge surface of the lower wallpaper, staining the lower wallpaper, so in order to prevent this, as shown in Figure 4. , Width 30 ~ made of thin synthetic resin film on the back side of the edge of the upper wallpaper 1A
After temporarily gluing 80mm cut tape 2 over the edge of pasted wallpaper 1B and cutting it with knife 3,
The separation edges 1a, 1b of the wallpapers 1A, 1B and the cut tape 2 were removed. In addition, 4 is a board wall, 5
is putty filled in the recessed portion of the plate wall 4.

(Problem that the invention aims to solve) In order to strengthen the adhesive strength of the wallpaper and prevent it from peeling off, it is necessary to apply thicker glue to the top, bottom, left and right edges of the wallpaper cut to a predetermined length than to the center. However, in the above method, the glue on the inside of the cut edge of the upper wallpaper 1A, that is, on the edge after cutting, adheres to the cutting tape 2 and is removed, so that the glue on the edge is removed. There will be less glue than in the center,
Adhesive strength was lower than expected and it became easy to peel off. Also, the part filled with putty 5 is wallpaper 1.
If it is located under the overlapping part of A and 1B, wallpaper 1
When cutting wallpapers A and 1B with knife 3, the edge of knife 3 may break putty 5, so wallpaper 1A
peeled off even more easily.

(Means for solving the problem) Dry water-soluble adhesive layers activated with water are provided on both the front and back sides of a thin paper tape. The paper tapes mentioned above are made of Western paper, printing paper, roll paper, thin paper, writing paper, ^etc. and have a basis weight of 20 to 50 g/m2. If the basis weight is less than 20 g/ ^m2 , it is too thin and lacks strength. However, the tape may be pulled and torn by the wallpaper during application or after drying.On the other hand, if it exceeds 50 g/ ^m2 , it is too thick and steps will appear on the wallpaper surface after application. The water-soluble adhesive layer is coated with a water-soluble synthetic adhesive, such as a water-soluble adhesive whose main components are PVA (polyvinyl alcohol), isobutene, maleic anhydride copolymer, PEO (polyethylene oxide), etc. , obtained by drying. In this case, the solid content of the water-soluble adhesive applied is 3 on both the front and back sides.
~10 g/cm ² , and if the solid content is less than 3 g/m ² , there is almost no effect, and if it exceeds 10 g/m ² , the glue will be wasted.

(Function) After cutting the overlapping parts of adjacent wallpapers and removing the cut edges and cutting tape, the wallpaper of this invention is pasted between these wallpapers and the wall along the edges of the two wallpapers. When the tape is sandwiched and pressed onto the wallpaper, the water-soluble adhesive layers on both the front and back sides of this wallpaper adhesive tape come into contact with the glue on the back side of the wallpaper and the glue adhered to the wall surface, and are activated by the moisture.
The edges of the wallpaper are strongly adhered to the wall surface through this wallpaper adhering tape, and peeling of the wallpaper is prevented.

(Example) A water-soluble adhesive containing PVA as the main component was applied with a roller to the front and back sides of roll paper with a basis weight of 40 g/m ² so that the solid content was 5 g/m ² . After drying, cut into 5cm wide pieces and
Wallpaper pasting tape 1 as shown in Figures and Figure 2
1 and wound it around a paper tube 12. In Figure 2,
11a is paper, and 11b and 11c are water-soluble adhesive layers, respectively.

Using a wallpaper pasting machine equipped with a pasting roller, apply starch paste to the back side of the wallpaper 1A, temporarily adhere the cutting tape 2 to one side of the wallpaper as in the past, and place this wallpaper 1A together with the pasted wallpaper 1B. Cut the overlapping part of the wallpaper 1A and 1B with a knife 3, remove the cut edges 1a and 1b and the cut tape 2, and press the cut end side of the wallpaper 1A to the board wall 4 so that the parts overlap. do. Next, the ends of the wallpapers 1A and 1B are peeled off, and the wallpaper sticking tape 11 (see Figure 3) is applied to the residue so that its center line matches the trace of the butt ends of the wallpapers 1A and 1B. Paste it so that it almost matches, and then paste the above wallpaper 1A, 1 on top of it.
Layer B again and press it, wallpaper adhesive tape 11
The water-soluble adhesive layer 11c on the bottom surface of the wallpaper comes into contact with the glue on the board wall 4, and the water-soluble adhesive layer 11b on the top surface of the wallpaper adhesive tape 11 comes into contact with the glue on the back surfaces of the wallpapers 1A and 1B and is activated. , 1B are strongly fixed to the plate wall 4.

(Effect of the invention) When pasting wallpaper, by interposing the wallpaper pasting tape of this invention between the wallpaper and the wall surface along the adjacent parts of the two wallpapers, it can be applied to the edges of the two wallpapers. Glue is added along the line, making the bond strong and preventing it from peeling off even if there is a putty filling on the wall. Furthermore, since the water-soluble adhesive layer of the wallpaper sticking tape is in a dry state, it is easy to handle.
