Problems solved by technology

[0003] Traditional paper tape, when spraying, painting, or using solvent on the back of the tape for a long time, the solvent can easily penetrate the tape layer and penetrate into the surface of the object to be pasted, and the solvent will easily cause the bonding force of the adhesive tape to deteriorate. When the tape is peeled off after completion, the glue remains on the surface of the object to be pasted; in addition, in some large bends or corners, because most of the paper has low strength and low deformability, the stressed side of the paper tape is easy to tear or break

Abstract

The invention provides an anti-penetration paper-based adhesive tape. The anti-penetration paper-based adhesive tape sequentially comprises a surface treatment layer, a paper substrate layer, a pressure-sensitive adhesive layer A, a PET film layer and a pressure-sensitive adhesive layer B. According to the anti-penetration paper-based adhesive tape provided by the invention, through embedment of the PET film layer between the paper substrate layer and the adhesive layer, the problems that during paint spraying and brushing or long-time use of a solvent on the back side of the adhesive tape, the solvent penetrates and adhesion of adhesive to paper is affected after solvent penetration, and during peeling again, the adhesive remains on the surface of an adhered object and the solvent causespollution and loss to the surface of the adhered object after penetration into the surface of the adhered object can be effectively improved; the PET film layer also can enhance the strength and the toughness of the paper, so that the paper does not break when applied to a large bent position and a corner; meanwhile, adhesion of the paper to a substrate can be enhanced; the surface of a paper material is generally an uneven porous surface and the adhesive difficultly completely penetrates therein, so that during using, point-type and sheet-type adhesive failure is easily caused; when PET is used as a carrier, the PET has relatively high surface energy and a smooth surface and has excellent bonding to the adhesive, so that the problems such as the adhesive failure and adhesive residual areavoided.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to an anti-permeation paper adhesive tape. Background technique [0002] Paper tape is based on paper, coated with pressure-sensitive adhesive glue, soft paper, good initial adhesion, and good holding power, easy to adhere to various surfaces, low labor intensity, can be masked film or The masking paper stays securely where you need it, avoiding slipping, falling off, etc. It is suitable for covering sports equipment, rubber and plastic parts and construction sites, indoor and outdoor decoration, decoration spraying and painting. Moderately sticky, it has good adhesion and shielding properties to most smooth surfaces, bends or corners, good workability, and can be removed quickly after use without leaving any adhesive residue, so it is widely used in many industries. [0003] Traditional paper tape, when spraying, painting, or using solvent on the back of the tape for a long time, the solvent c...
