Problems solved by technology

This leads to low adhesion when silicon dioxide is used as a low refractive index optical coating material to form a film layer on the surface of plastic components, resulting in film cracking, film removal, etc.
At present, there is no single low-refractive index coating material in the domestic and foreign optical coating material market that can solve this problem well, and there is no similar patented technology

Abstract

The invention discloses a low-refractive-index optical coating material. The optical coating material is prepared from silicon dioxide and an additive, and the additive is selected from one or more of aluminum oxide, magnesium oxide and yttrium oxide.

Description

technical field [0001] The invention relates to a low-refractive-index optical coating material, which belongs to the field of optical coating materials. Background technique [0002] In the field of optical coatings, silicon dioxide is the most commonly used low-refractive optical index coating material, but with the development of technology and applications, many traditional glass optical components are now mostly replaced by plastic components, such as camera lenses, etc., and some mobile phone casings Parts, which are themselves plastic components. Compared with glass optical components, these plastic components have low temperature resistance and large expansion coefficient. When coating plastic components, the substrate temperature in the coating machine is not as high as that of coated glass components. This leads to low adhesion when silicon dioxide is used as a low-refractive-index optical coating material to form a film on the surface of a plastic component, resu...
