Abstract

The invention discloses a kind of ultraviolet light sodifying hardening liquor, comprising 5-40wt% of high function aliphatics urethane acrylate, 5-15wt% of annular single function acrylic ester monomer, 5-10wt% of double function 2 functional aliphatics urethane acrylate, 5-25wt% of 2 functional acrylic ester, 1-5wt% of photoinitiator, 20-60wt% of diluent, 0.01-1wt% of auxiliary agent, suitable for optical thin film; resin lens of optical level such as PMMA, PS, PC, CR, PVC; liquid crystal screen; vehicle space and rupture membrane; glass lens and so on. The high crosslinking density provides great hardness. The annular single function acrylic ester monomer has low viscosity to provide levelling property and annular structure to ensure the good hardness of the resin lens.

Description

technical field [0001] The invention relates to an ultraviolet curing coating, in particular to a hardened protective coating on optical film, optical grade PMMA, PS, PC, CR, PVC and other resin lenses. Background technique [0002] Portable electronic products have become fast-moving consumer goods and have increasingly become a part of people's lives, and have higher and higher requirements for appearance. Most digital products have various lenses such as LCD windows, PMMA, PC, PS, etc. These inspections The lens is easy to break, scratch and other disadvantages. So far, no similar patented technology has been found. Most of the actual domestic use uses imported products from Japan and South Korea, and the market prospect is broad. Contents of the invention [0003] The invention solves the problems of digital product LCD viewing window, optical film, optical-grade PMMA, PS, PC, CR, PVC and other resin lenses that are easy to be broken, scratched, not wear-resistant, not...
