2018-06-29 425

After three years of scientific and technological research, China's optical film precision micro-replication technology has made a major breakthrough and successfully broke the monopoly of foreign technology. This is the news that the reporter obtained from the Hubei Provincial Defense Science and Technology Office and the Hubei Aerospace Chemical Technology Research Institute on the 10th.

According to reports, the optical micro-precision micro-replication technology is a technique of precisely coating a specific formulation resin on the surface of an optical film substrate and then molding it on an engraving roll having a specific design nano-scale geometry. It is widely used in liquid crystal flat panel display backlight module brightness enhancement film and diffusion film, road traffic sign microprism reflective film, liquid crystal display protection anti-reflection film and anti-reflection film, naked eye 3D display functional film and household metal imitation metal wire high gloss film Wait. These products have high added value, large market demand, and key technologies have always been in the hands of foreign companies.

From 2014 to 2016, Hubei Aerospace Chemical Technology Research Institute undertook the development and application of key technologies for optical micro-precision micro-replication process in Hubei Province. It has carried out structural design, engraving resin formulation research and coating process research. Acceptance by the Science and Technology Department of Hubei Province.

The relevant person in charge of Hubei Aerospace Chemical Technology Research Institute said that they designed a special surface coating microstructure, developed a special engraved coating resin formula, and used anti-glare, anti-scratch or anti-static treatment on the back of the optical film engraved coating to improve The product yield is over 20%, which greatly improves the scientific and technological level of China's new material industry chain.

According to reports, at present, this technology has been applied in important national defense projects, and 10 invention patents have been filed.
