Abstract

The invention discloses an ultraviolet-cured hard coating and an application thereof. The ultraviolet-cured hard coating comprises a transparent supporting body and a scratch-proof coating coated on the transparent supporting body; the scratch-proof coating comprises the following components in part by weight: 5 to 90 parts of light-cured prepolymer, 5 to 90 parts of thinning agent, 1 to 10 parts of photoinitiator, 0 to 80 parts of active thinning agent, 0 to 20 parts of inorganic nanopadding and 0 to 18 parts of aid. By the invention, the defects that the conventional hard coating is not hard enough, the scratch resistance and the wear resistance are limited, the flexibility is relatively low and the like are overcome; and the ultraviolet-cured hard coating has relatively low surface energy, relatively good antifouling effect, high strength, relatively good scratch resistance and wear resistance, and excellent adhesion, flexibility and transparence.

Description

technical field [0001] The invention relates to an ultraviolet curing hard coating film used for protecting various displays and touch screens. Background technique [0002] In recent years, various new flat panel display (LCD, OLED, EL, PDP) technologies and products have developed rapidly. The flat panel display industry has become an important part of the information industry. The flat panel display industry and market are growing rapidly worldwide. Related manufacturing materials And the parts market has also developed rapidly, especially the optical thin film materials used in display technology are in a rapid growth trend. Various optical film materials, such as reflective film, anti-reflection film, filter film, optical protective film, polarizing film, spectroscopic film and phase film, are very easy to be scratched and stained during manufacture and use, so surface treatment is required. To improve the scratch resistance, abrasion resistance and antifouling perform...
