Abstract

PROBLEM TO BE SOLVED: To provide a self-adhesive tape of which the substrate is a woven fabric having a brightly colored back and which is excellent in weatherability. SOLUTION: At least three differently colored polyolefin films are laminated onto the back, i.e., a side other than the side coated with a self-adhesive, of a substrate. The first film directly bonded to the back is a black ultravioletscreening polyolefin film or a white ultraviolet-scattering polyolefin film. When the first film is black, then the second film, i.e., the intermediate layer, is a white polyolefin film, and when the first film is white, then the second one is a black polyolefin film or a polyolefin film with the same color as that of the third film, i.e., the uppermost layer. The third film is a polyolefin film colored as required.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth adhesive tape used for curing, packaging and the like, and more particularly, to an adhesive tape based on a woven fabric, in which the color of the back color of the woven fabric is vivid, and There is little deterioration of the adhesive due to sunlight, etc.
The present invention relates to a cloth adhesive tape having excellent weather resistance.

[0002]

2. Description of the Related Art Conventionally, cloth adhesive tapes used for curing, packaging, etc., are generally made of one layer or two layers on a cloth or cotton cloth.
It is made by applying a natural rubber-based adhesive to a work cloth in which a layer of polyethylene film is laminated, and has good adaptability of adhesion to rough surfaces and can be easily cut by hand. It is widely used as a feature.
In particular, cloth adhesive tapes for curing are often used outdoors,
Used under severe conditions such as wind and rain, sun rays, and temperature changes. However, the conventional cloth adhesive tape for curing is 1
Despite use for up to two months, there is a problem of deterioration of the pressure-sensitive adhesive due to ultraviolet rays and the like, and a problem of adhesive residue on an adherend due to the deterioration. In order to solve this problem, the present inventors, in the registered utility model publication No. 3005686,
To prevent the adhesive from deteriorating due to ultraviolet rays, a black polyethylene film that blocks the transmission of ultraviolet rays is laminated on the back of the woven fabric, and a colored film that conceals the black polyethylene film is laminated on the upper layer. Suggest a tape.

[0003]

By laminating a black polyethylene film for blocking the transmission of ultraviolet light on the back of the woven cloth of the cloth adhesive tape, it is possible to surely prevent the adhesive from deteriorating due to ultraviolet light. Also, it has become possible to greatly reduce the adhesive residue on the adherend. But,
When a black polyethylene film is laminated on the first layer and a colored polyethylene film is laminated on the second layer, the back color of the woven fabric of the cloth adhesive tape becomes dark, and the original vivid color of the colored polyethylene film is developed. It was extremely difficult.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a cloth adhesive tape which has a vivid back color of the woven fabric of the cloth adhesive tape and is excellent in weather resistance. Is to do.

[0005]

Means for Solving the Problems In order to achieve the object of the present invention, the present invention is configured as described in the claims. That is, the present invention, as described in claim 1, in a pressure-sensitive adhesive tape based on a woven fabric, from the substrate surface side opposite to the pressure-sensitive adhesive-coated surface of the substrate, sequentially,
At least three layers of polyolefin film layers each colored in a predetermined color are laminated to form a cloth adhesive tape provided with a film layer having a laminated structure with clear colors and excellent weather resistance. In addition, as described in claim 2, in the present invention, among the three-layered colored polyolefin film layers, the first colored polyolefin film layer adjacent to the base material has a thickness of 10 to 10 in claim 1. The cloth adhesive tape is a 20 μm white or black polyethylene film layer. According to the present invention, the third colored polyolefin film layer, which is the uppermost layer, of the three-layered colored polyolefin film layer according to the first aspect, has a thickness of 15 to 40 μm. Of a cloth adhesive tape formed into a polyethylene film layer colored in a predetermined color. Further, according to the present invention, when the first colored polyolefin film layer adjacent to the base material is a black polyethylene film layer, the second colored polyolefin corresponding to the intermediate layer according to the first aspect of the present invention. A cloth adhesive tape in which the film layer is a white polyethylene film layer having a thickness of 20 to 40 μm. Further, according to the present invention, in the case where the first colored polyolefin film layer adjacent to the substrate is a white polyethylene film layer, the second colored polyolefin corresponding to the intermediate layer according to the first aspect of the present invention. The film layer is a white polyethylene film layer having a thickness of 20 to 40 μm, or the same color as the third colored polyolefin film layer as the uppermost layer has a thickness of 20 to 40 μm.
m, which is a cloth adhesive tape having a polyethylene film layer. The cloth adhesive tape using a woven fabric as a base material of the present invention has a structure in which at least three colored polyolefin films are laminated on a base material surface opposite to a surface coated with an adhesive. That is, the first polyolefin film layer adjacent to the base material blocks transmission of ultraviolet light,
For example, a black polyolefin film, or a layer that scatters ultraviolet light, for example, a white polyolefin film is laminated, and when the first film layer is a black polyolefin film layer, a second film layer corresponding to an intermediate layer is formed. When a white polyolefin film layer is laminated and the first film layer is a white polyolefin film layer, the second film layer corresponding to the intermediate layer is a white polyolefin film or the third layer which is the uppermost layer.
And a polyolefin film layer of the same color as the film layer of the above is laminated, and a polyolefin film layer colored in a predetermined color is laminated as a third film layer. As the polyolefin film layer used for the cloth adhesive tape of the present invention, a polyethylene film layer is most preferably used. The thickness of each layer of the colored polyolefin film is 10 to 20 μm for the first polyolefin film layer adjacent to the base material, and 20 to 4 μm for the second polyolefin film layer corresponding to the intermediate layer.
It is preferable that the thickness of the third polyolefin film layer, which is the uppermost layer, is in the range of 15 to 40 μm. Also,
As the adhesive, a natural rubber-based adhesive is generally used. The cloth adhesive tape of the present invention is characterized in that:
By the configuration as described in the above, the color of the back color of the woven fabric of the cloth adhesive tape is vivid, and excellent in weather resistance, as a result, even after long-term outdoor use, This has the effect of realizing a cloth adhesive tape free of adhesive residue and the like.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The cloth adhesive tape of the present invention will be described more specifically with reference to an example of an embodiment of the present invention. As shown in FIG. 1, a base material 5 made of soft cloth
On one side, a black polyethylene film layer 1 having a thickness of about 10 μm was provided as a first layer, and a white polyethylene film layer 2 was provided as a second layer having a thickness of about 20 μm. . Further, as a third layer, a blue polyethylene film layer 3 having a thickness of about 20 μm was provided. Next, a cloth adhesive tape in which a natural rubber-based adhesive was applied to about 75 μm on the other surface of the base material 5 made of soft cloth to form an adhesive layer 4 was produced. As a result, the color of the back color of the woven cloth of the cloth adhesive tape is vivid and has excellent weather resistance,
As a result, it was possible to obtain a good cloth adhesive tape free of adhesive residue and the like even after long-term outdoor use.
