Abstract

The invention provides an elastic pressure-sensitive adhesive layer, a pressure-sensitive adhesive tape, and a preparation method of the pressure-sensitive adhesive tape. The elastic pressure-sensitive adhesive layer and the elastic pressure-sensitive adhesive tape utilize a technology that a main body material structure reacts with water to generate a gas causing volume expansion, so that the elastic pressure-sensitive adhesive layer and the elastic pressure-sensitive adhesive tape have elasticity; the limitation of a traditional foam tape is broken through, the elastic pressure-sensitive adhesive layer and the elastic pressure-sensitive adhesive tape can have good buffering performance and compressibility without using foam as a base material, and are superior to a foam adhesive tape inthe aspect of die cutting stability; and the thickness, the viscosity and the compressibility of the elastic pressure-sensitive adhesive layer and the elastic pressure-sensitive adhesive tape can be customized according to actual application requirements, so the elastic pressure-sensitive adhesive layer and the elastic pressure-sensitive adhesive tape have very flexible practicability.

Description

technical field

[0001] The invention relates to the technical field of pressure-sensitive adhesive tapes, in particular to an elastic pressure-sensitive adhesive layer, an elastic pressure-sensitive adhesive tape and a preparation method of the elastic pressure-sensitive adhesive tape. Background technique

[0002] As all kinds of smart electronic products have more and more stringent requirements on anti-drop, anti-deformation, waterproof and dustproof, hardware manufacturers urgently need high-performance cushioning and energy-absorbing materials to realize the above functions. The mainstream design solution currently on the market is to use various types of foam tapes to achieve these functions.

[0003] Foam tape is a kind of tape product made of foam as the base material. This tape is thicker than ordinary tape, has better sealing and shock absorption effect, and can be used in many occasions. Common foams are polyolefin or polyurethane foaming materials. Polyolefin or...
