Description

[Detailed description of the invention] (Field of industrial application) The cut tape for pasting wallpaper of this invention is used when pasting wallpaper on the walls or ceiling of a house, after applying adhesive to the back side of the wallpaper, one edge of the cut tape is applied. It is used by temporarily gluing it along the

(Prior art) When pasting wallpaper on the walls and ceilings of houses, conventionally starch paste was applied uniformly to the entire back side of the long wallpaper.
Cut this to a specified length, then paste this wallpaper next to the already pasted wallpaper so that some overlap to match the pattern, and use the tip of a knife to cut the overlapping part lengthwise. After cutting off the overlapping parts, removing the edges separated by the above cutting from both wallpapers, crimping both wallpapers to the wall again, and abutting the cut edges. It was attached.

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 3. , Width 30 ~ made of thin synthetic resin film on the back side of the edge of wallpaper 1A that will be on top.
An 80 mm cut tape 2 was temporarily attached and overlapped on the edge of the pasted wallpaper 1B, cut with a knife 3, and then the cut tape 2 was removed together with the separated edges 1a and 1b of the wallpapers 1A and 1B. Note that 4 is a wall.

(Problem that the invention aims to solve) In order to strengthen the adhesion 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 compared to the center. However, in the above method, the glue on the inner side of the cut edge of the upper wallpaper 1A, that is, on the edge after cutting, adheres to the cut tape 2 and is removed, so the above edge is removed. There was a problem that the amount of glue in the area was less than that in the center, and the adhesive strength was reduced, making it easier to peel off.

(Means for solving the problem) A dry water-soluble adhesive layer that is activated with water is applied to one side of a cut tape made of a synthetic resin film, and this water-soluble adhesive layer is applied to the starch paste coated side of the back side of the wallpaper. The adhesive layer is activated when stacked and is transferred to the wallpaper when the tape is peeled off from the wallpaper. This water-soluble adhesive layer is a water-soluble synthetic adhesive, such as an adhesive whose main component is PVA (polyvinyl alcohol), PAAm (polyacrylamide), isobutene/maleic anhydride copolymer, PEO (polyethylene oxide), etc. It is obtained by applying and drying. In this case, the solid content of the water-soluble adhesive applied is 8 to 20 g/ ^m2 ,
In particular, 10 to 15 g/ ^m2 is preferable; if the solid content is less than 8 g/ ^m2 , there will be little effect;
If it exceeds g/ ^m2 , the glue will be wasted. In addition, the film that serves as the base material for cut tape is polyethylene,
Made of synthetic resin such as polypropylene, thickness 0.04~
It is 0.1mm. The thickness of this film is 0.04
If it is less than that, the strength of the tape itself will be insufficient and it will stretch too much.
On the other hand, if it exceeds 0.1 mm, the rigidity of the tape will be too strong, making it difficult to temporarily adhere to and peel off the wallpaper.

(Function) When the surface of the water-soluble adhesive layer of the cut tape is placed on the back edge of the wallpaper to be placed on top, the water-soluble adhesive layer of the cut tape is supplied with water from the glue on the back side of the wallpaper and becomes activated. The water-soluble adhesive layer is transferred to the back edge of the wallpaper. Therefore, the adhesive force at the back edge is strengthened. Moreover, since the film surface of the cut tape is superimposed on the edge surface of the wallpaper that has already been pasted, the edge surface of the wallpaper will not get dirty.

(Example) A water-soluble adhesive mainly composed of PVA was applied with a roller to one side of a biaxially stretched polyethylene film with a thickness of 0.05 mm at a solid content of 10 g/ ^m2 , and after drying. , cut to a width of 5 cm to make cut tape 11 for pasting wallpaper as shown in Fig. 1,
It was wound up on a paper tube 12.

Using a wallpaper gluing machine with a gluing roller, apply starch paste to the back side of the wallpaper 1A, overlap the cut tape 11 above along the back side of the wall edge, and
As shown in the figure, the above wallpaper 1A is adhered to the wall 4 so that it partially overlaps the pasted wallpaper 1B. In addition, in FIG. 2, 11a is the cut tape 11.
The film 11b is a water-soluble adhesive layer. Next, the overlapping part of the wallpapers 1A and 1B is cut with the knife 3, the separated parts 1a and 1b of the wallpapers 1A and 1B and the cut tape 11 are removed, and the cut end side of the wallpaper 1A is pressed onto the wall 4.

(Effect of the invention) By temporarily adhering the cutting tape of this invention to the edges of the wallpaper and peeling it off, the water-soluble adhesive layer of the cutting tape is transferred to the back side of the edges of the wallpaper, strengthening the adhesive strength of the edges of the wallpaper. This prevents the wallpaper from peeling off from the wall surface. Moreover, since the back side of the edge of the wallpaper is covered with cut tape and then stacked on the pasted wallpaper, the surface of the pasted wallpaper will not get dirty.
