Problems solved by technology

Ordinary rubber-based pressure-sensitive adhesives have poor UV resistance, but good pressure sensitivity, and the pressure-sensitive adhesives made have good wettability. Saturated synthetic rubber EPDM and SEBS have better UV resistance, but they are made of Poor pressure sensitivity
Therefore, the existing ordinary rubber-based pressure-sensitive adhesives cannot simultaneously meet the two conditions for good outdoor application of masking tape, that is, good wetting and bonding effect and UV resistance.

Abstract

The embodiments of the present invention provide an anti-UV masking paper adhesive tape, which is sequentially provided with a release layer, a masking paper substrate layer, an anti-UV adhesive layerand a common rubber-based pressure-sensitive adhesive layer, wherein the anti-UV adhesive layer comprises, by weight, 300 parts of toluene, 20-30 parts of an inorganic filler, 100 parts of a saturated synthetic rubber, 10-90 parts of a hydrogenated petroleum resin, 1-3 parts of an antioxidant, and 1-3 parts of an UV absorber. According to the present invention, the anti-UV masking paper adhesivetape is coated with the two layers of the adhesive layers, wherein the adhesive layer with characteristics of excellent anti-UV performance and poor pressure-sensitive performance is coated with the common rubber-based pressure-sensitive adhesive layer, such that the requirements of anti-UV performance and adhesion performance can be simultaneously met, and the production process is simple.

Description

technical field [0001] The invention relates to a masking tape, in particular to an anti-UV masking tape. Background technique [0002] Masking tape is widely used in automotive painting, home decoration, electronics industry and other fields. According to the application occasions, it can be roughly divided into indoor and outdoor applications. Since masking tapes are mostly coated with natural rubber-based pressure-sensitive adhesives, ordinary rubber-based pressure-sensitive adhesives usually have poor anti-UV (ie ultraviolet) effects, thus limiting the outdoor application of masking tapes. [0003] Masking tape can be divided into many types according to the substrate, application, and glue type. Generally speaking, the common tape structure generally includes three parts: release layer, substrate, and adhesive layer. At present, there are two main ways to improve anti-UV, that is, shielding reflection and absorbing UV light. Shielding and reflecting ultraviolet rays ca...
