Abstract

The invention discloses paint for a polycarbonate lens. The paint for the polycarbonate lens comprises the following raw materials in parts by weight: 100 parts of a silicon resin prepolymer, 2-5 parts of polyborosiloxane, 1-3.8 parts of epoxy resin, 1-3.5 parts of amino resin, 0.1-1 part of hydroxy terminated polyester, 0.2-1.2 parts of carboxyl terminated polyester, 0.1-0.25 parts of tetrabutylammonium hydroxide, 0.2-0.6 parts of methylhexahydrophthalic anhydride, 0.05-0.12 parts of 2-methylimidazole, 0.1-0.5 parts of bicyclic amidine, 3-9 parts of ethyl alcohol, 5-15 parts of n-butyl alcohol, 1-3 parts of modified nano-zinc oxide, 0.3-1 part of nano zirconium dioxide, 0.5-2 parts of nano titanium dioxide, and 0.05-0.25 parts of an ultraviolet absorber. The provided paint for the polycarbonate lens is good in abrasive resistance, high in hardness, excellent in ultraviolet resistance, and high in adhesive force with the polycarbonate.

Description

technical field [0001] The invention relates to the technical field of coatings for lenses, in particular to a coating for polycarbonate lenses. Background technique [0002] Polycarbonate is a thermoplastic resin with a carbonate bond structure in its main molecular chain. It has the advantages of light weight, high transparency, good impact resistance, heat resistance, cold resistance, stable size, high light transmittance, and easy processing and molding. It has been widely used as a material for optical lenses, lenses, etc., but compared with optical glass, polycarbonate has low surface hardness and poor wear resistance. In order to prolong the service life of polycarbonate lenses, the most common method is coating , which is the most widely used organosiloxane system, but the existing silicone coating has poor adhesion to polycarbonate, and the abrasion resistance and UV resistance are not very good, which limits its use in polycarbonate lenses Applications.
