Abstract

This invention discloses a transparent and abrasion-resisting organic silicon coating that comprises component A 83.3-86.7 vol. % and component B 13.3-16.7 vol. %. Component A is composed of organic silicon monomer 25-31 vol. %, leveling agent 0.2-1 vol. % and solvent 68-74.6 vol. %. Component B is compose of concentrated hydrochloride acid 6.2-9.9 wt.%, water 89.7-93,1 wt.% and curing agent 0.4-1.1 wt.%. The coating in this invention has such advantages of long storage time and simple usage. Once applied on the surface of optical plastics, the coating layer has obvious enhancement effects, and can improve the abrasion-resistance and transparency of the optical plastics.

Description

technical field [0001] The invention relates to a silicone wear-resistant transparent paint, in particular to a silicone wear-resistant paint used for enhancing the surface of optical plastics. Background technique [0002] Optical plastics are often used as optical components because of their low density, good impact resistance, and easy processing and molding. However, its friction resistance and solvent resistance are not good, which limits its application range. Improving the surface hardness of such materials through surface enhancement is a simple and practical method that can expand the application fields of such materials, such as making various lenses and spectacle lenses. Among the surface enhancing materials, the wear-resistant transparent coating has been widely used because of its simple process, convenient operation, low cost and excellent performance. Among them, it is more common to obtain polyorganosiloxane wear-resistant coatings by hydrolysis and film fo...
