Title:
ELASTIC PRESSURE-SENSITIVE ADHESIVE LAYER, PRESSURE-SENSITIVE ADHESIVE TAPE, AND METHOD FOR PREPARING PRESSURE-SENSITIVE ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2021/057254
Kind Code:
A1
Abstract:
The present invention provides an elastic pressure-sensitive adhesive layer, a pressure-sensitive adhesive tape, and a method for preparing the pressure-sensitive adhesive tape. The elastic pressure-sensitive adhesive layer and the elastic pressure-sensitive adhesive tape provided by the present invention utilize the technique of reacting the structure of a main material with water to generate a gas and expand the volume of the material, to provide elasticity to the adhesive layer and adhesive tape. The present invention overcomes the limitations of traditional foam tapes, and has good cushioning and compressibility without the need to use foam as a base material, and is superior to foam tapes in terms of die-cutting stability. Furthermore, in the present invention, the thickness, viscosity, and compressibility of the elastic pressure-sensitive adhesive layer and the elastic pressure-sensitive adhesive tape can be customized according to actual application requirements, and have high flexibility in practice.
