Abstract

The invention provides UV glue and a preparation method thereof. The UV glue is prepared from the following ingredients of 35 to 60 weight parts of prepolymer, 35 to 50 weight parts of monomer and 1 to 6 weight parts of photoinitiator, wherein the prepolymer is epoxy acrylate and / or modified polyurethane acrylate, and the monomer is chosen from one or several of (methyl) isobornyl acrylate, tetrahydrofuran acrylate and hydroxyethyl methylacrylate. The UV glue can be applied to the surface of a silver-coated material, has the characteristics of high bonding strength, small viscosity, high fluidity, good wear resistance and the like and overcomes the defects of existing photochemical solidification adhesive.

Description

technical field [0001] The invention relates to the technical field of ultraviolet curing coatings, and more specifically, relates to a UV glue and a preparation method thereof. Background technique [0002] Ultraviolet light curing (i.e. UV curing) refers to the chemical reaction of photosensitive substances in the system under the action of ultraviolet light to produce active fragments, which trigger the polymerization and crosslinking of active monomers or oligomers in the system, so that the system can be coated from a liquid state. The layer instantly becomes a solid coating. Ultraviolet light curing glue (UV glue) has been widely studied due to its many outstanding advantages such as fast curing speed, environmental friendliness, low energy consumption, and no solvent volatilization. It is mainly used in: electronics industry, optical product industry, medical equipment, decoration materials industry. As people pay more and more attention to environmental protection,...
