OCA optical cement is an optically transparent substrate-free double-sided tape, the technology is mature in application, the optical cement is particularly suitable for small-size lamination, but the lamination difficulty is large, the required precision is high, bubbles are easily generated in lamination, rework cannot be performed, the lamination assembly can only be treated as a defective product, particularly, the lamination bubbles are more obvious, and the scrapping is very expensive. The LOCA is a liquid optical cement, is generally made of a liquid acrylate prepolymer, is also suitable for bonding book touch screens, and easily causes the problems of glue overflow, bubbles, shrinkage, yellow spots and the like in the process of a bonding process.
A new optical adhesive film material is also emerging in recent years, for example, patent CN 104356967A proposes an ultraviolet light curing polyolefin optical film, but has the problems of insufficient light transmittance of olefin, low adhesive force, incompatibility with hydroxyl-containing acrylate monomer and the like. Patent CN 103820042a proposes a thermosetting and UV curing optical transparent hot melt adhesive film, which adopts butadiene rubber, styrene butadiene rubber, ethylene propylene diene monomer, silicone rubber and the like with insufficient light transmittance and poor compatibility with reactive diluents. TPU, although having a certain compatibility with reactive diluents, is still inadequate, and has inadequate initial cohesion and a high melting point. The present invention is directed to solving the above problems.
