Abstract

The invention relates to an ultraviolet light curing optical adhesive. By weight, the ultraviolet light polymerization optical adhesive comprises 50-100 parts of prepolymer, 20-90 parts of inertia resin, 35-70 parts of monomer, 5-12 parts of photoinitiator, 2-3 parts of coupling agents and 1-2 parts of addition agents. Contraction generated by curing of the ultraviolet light curing optical adhesive is very small, hardness of curing material is small, the flexibility of molecular chains is high and internal stress generated by curing is further absorbed.

Description

technical field

[0001] The invention relates to an ultraviolet light curing adhesive, in particular to an ultraviolet light curing optical adhesive. Background technique

[0002] At present, more and more display devices adopt touch screen as a very intuitive human-computer interaction mode, such as mobile phones, tablet computers, digital cameras, GPS navigators and so on. The capacitive touch screen has the characteristics of precise positioning, fast response, high resolution, good durability, etc., and can realize multi-touch, and is adopted more and more.

[0003] In the past, when manufacturing capacitive touch screens, optically transparent adhesive (OCA film) was generally used to bond the various layers of materials. When laminating OCA film, the elimination of air bubbles is a very difficult problem to solve, and its reliability is average, and the cost is high, so it is only suitable for the lamination of small and medium-sized screens of 2 to 7 inches.
