Abstract

The invention discloses an ultraviolet curing adhesive with high temperature resistance and a preparation method of the ultraviolet curing adhesive, and belongs to the technical field of preparation of photocuring materials. The technical problems that an existing ultraviolet curing adhesive cannot keep the adhesive performance under the high-temperature condition and is prone to falling off in the production process are solved. The ultraviolet curing adhesive comprises an acrylate prepolymer, an active monomer, a photoinitiator and an auxiliary agent. Wherein the acrylic acid prepolymer is a mixture of organic silicon modified acrylate and methacrylate type liquid isoprene rubber. According to the invention, a manner of modifying acrylate is adopted, a group structure with high temperature resistance is introduced into an acrylate prepolymer, and the modified acrylate and methacrylate isoprene are blended according to a certain proportion, so that the prepolymer with excellent high temperature resistance is prepared; by optimizing the formula, the ultraviolet curing adhesive which can still keep good adhesive performance in a high-temperature environment is obtained.

Description

technical field [0001] The invention belongs to the technical field of preparation of light-curing materials, in particular to a preparation method of an ultraviolet light-curing adhesive with high temperature resistance. Background technique [0002] Due to its fast curing speed, environmental friendliness, low energy consumption, no solvent volatilization, lower system cost, and high safety performance, UV-curable adhesives are constantly expanding in the application fields of mobile phones, TVs, computers and other electronic products. The amount and scope of use are also getting wider and wider. However, UV-curable adhesives also have their own limitations. The existing conventional UV-curable adhesives have obvious limitations in the application of high temperature. adhesive properties. As for the process protection of high-performance tempered glass (such as mobile phone glass, etc.) and the laser engraving process of mobile phone metal back cover, special processes ...
