Problems solved by technology

[0002] The UV optical glue used in the existing microprism anti-glare film UV coating process is mostly a relatively viscous glue with poor fluidity at room temperature. After curing, the adhesion to PET and PC films is average, and the glue is relatively brittle after molding. The tip of the structure is easy to break, and it is easy to cause scratches and other defects when customers install it

Abstract

The invention discloses UV (ultraviolet) optical adhesive, made from, by weight, 30-60 parts of an acrylate oligomer, 30-50 parts of an acrylate monomer, 1-4 parts of a photopolymerization initiator,and 3-5 parts of an adhesion promotion aid. The UV optical adhesive has the advantages that the finished adhesive has reliable indexes, the yield is increased, fewer defects are shown to customers, mobility and curing speed of the adhesive are increased, and coating speed is increased so that production efficiency is improved.

Description

technical field [0001] The invention relates to the field of microprism anti-glare film and plate manufacturing, in particular to UV optical glue used in the microprism anti-glare film UV coating process. Background technique [0002] The UV optical glue used in the existing microprism anti-glare film UV coating process is mostly a relatively viscous glue with poor fluidity at room temperature. After curing, the adhesion to PET and PC films is average, and the glue is relatively brittle after molding. The tip of the structure is easy to break, and it is easy to cause scratches and other defects when customers install it. Contents of the invention [0003] The purpose of the present invention is to provide a UV optical glue, which increases the fluidity and curing speed of the glue, so that the coating speed can be increased, thereby improving the production efficiency. [0004] To achieve the above object, the technical solution of the present invention is [0005] A kin...
