Abstract

The invention belongs to the technical field of adhesive materials, and relates to a UV viscosity-reducing adhesive and a UV viscosity-reducing adhesive tape. In order to solve the problem of high peel strength of a viscosity-reducing film formed by an existing UV viscosity-reducing adhesive after UV irradiation, the invention provides the UV viscosity-reducing adhesive and the UV viscosity-reducing adhesive tape. The UV viscosity-reducing adhesive is prepared from the following components in parts by mass: 30 to 50 parts of acrylate resin, 5 to 10 parts of cationic cured resin, 7 to 14 parts of a polyfunctional monomer, 0.1 to 1 part of a free radical photoinitiator, 0.1 to 1 part of a cationic photoinitiator and 2 to 4 parts of a cross-linking agent. The peeling strength of a glue film formed by the UV viscosity-reducing glue is high before UV irradiation, and the peeling strength is low after UV irradiation. The UV viscosity-reducing adhesive tape prepared from the UV viscosity-reducing adhesive is high in initial adhesive force, can be adhered to a protected material without falling off, is low in adhesive force after being irradiated by UV light, is easy to peel off from the protected material, and is not easy to leave residual adhesive.

Description

technical field [0001] The invention belongs to the technical field of adhesive materials, and relates to a UV visbreaking adhesive and a UV visbreaking tape. Background technique [0002] With the rapid development of science and technology, the upgrading of the electronics industry is also very rapid. Wafer dicing, semiconductor chips, OCA bonding and positioning, and many other fields have an increasing demand for UV adhesion-reducing protective films. This kind of tape should have the purpose of stable positioning in the initial stage, and play a protective role in cutting or etching processes. After UV irradiation, it should be easily removed without leaving any residue. It maintains a high adhesive force at the initial stage, and rapidly reduces the adhesive force after UV irradiation. The principle of realizing this process is that after UV irradiation, the double bonds of a large number of oligomers inside the tape undergo cross-linking reactions. g Rapidly rises ...
