Background

In the existing market, Japanese paper or crepe paper is used as a base material of an adhesive tape, impregnation treatment is firstly carried out in the first step, the strength of the paper is improved, the adhesive property of rubber type glue on the Japanese paper is improved, the glue permeation inside the paper is reduced, a release layer is coated on one surface in the second step, and a rubber pressure-sensitive adhesive is coated on the other surface in the third step, so that the paper adhesive tape is obtained. The paper adhesive tape is soft, has good initial adhesion, good retention, low unwinding force, easy adhesion to various surfaces and low labor intensity, can be conveniently attached to a required position, and plays roles of shielding, fixing, protecting, branching, bundling and the like. Is suitable for covering sports equipment, rubber and plastic parts and building sites, indoor decoration, decoration and painting. The adhesive has low peeling force, good wetting and fitting properties, good adhesive and shielding properties on most smooth surfaces, bends or corners, good operability, quick tearing after use, no residual adhesive, and no damage to the surface of an adherend, thereby being widely applied to a plurality of industries.

However, when the conventional paper adhesive tape is attached to a wall surface (a putty powder wall or a latex paint wall) in decoration or attached to the wall surface for a long time, the wall surface is easily damaged by removing the conventional paper adhesive tape. In particular, the low-viscosity home decoration paper adhesive tape made of the existing water adhesive has the problems that the adhesive tape is removed under the condition of not being dried when water paint is brushed, the adhesive tape can have the condition of adhesive residue, and the wall surface can be damaged when the adhesive tape is attached to the normal thin-paint wall surface for removal.

Therefore, in order to overcome the defects of the prior art, a completely new adhesive tape needs to be developed.
