Abstract

The invention relates to an anti-yellowing and ultraviolet-proof coating. The anti-yellowing and ultraviolet-proof coating is prepared from, by weight, 30-35 parts of glass ionomer cement, 15-20 partsof ethylene glycol, 5-10 parts of glacial acetic acid, 1-3 parts of antioxidant IRGASTAB PUR 68, 1-3 parts of light stabilizer Tinuvin B 75 and 1-3 parts of zinc oxide powder. According to the anti-yellowing and ultraviolet-proof coating, the glass ionomer cement is added in the formula, so that the coating has a super-strong wear resistant property; the added antioxidant IRGASTAB PUR 68 belongsto an amine-free formula, and the anti-yellowing capacity can be improved; the added light stabilizer Tinuvin B 75 has an anti-yellowing capacity.

Description

technical field [0001] The invention relates to the field of glasses manufacturing, in particular to an anti-yellowing and anti-ultraviolet coating for glasses. Background technique [0002] Resin lens is an organic material with a polymer chain structure inside, which is connected to form a three-dimensional network structure. The intermolecular structure is relatively loose, and there is a space for relative displacement between molecular chains. The light transmittance is 84%-90%, the light transmittance is good, and the optical resin lens has strong impact resistance. [0003] Existing eyeglasses generally all select resin lens for use, and existing eyeglass surface all can be coated with coating, and coating can turn yellow after long-time sunlight exposure. [0004] In view of the above-mentioned defects, the designer actively researches and innovates in order to create a kind of anti-yellowing and anti-ultraviolet coating, so that it has more industrial utilization v...
