Abstract

The invention relates to an ultraviolet shielding nano coating liquid which is prepared from the following components in parts by weight: 40 to 60 parts of acrylic resin, 10 to 25 parts of dispersing type silica sol, 3 to 8 parts of ultraviolet shielding agents, 1 to 5 parts of silane coupling agents, 0.05 to 8 parts of auxiliary agents and 20 to 50 parts of water, wherein the ultraviolet screening agent is a TiO2 / porous organic carrier compound prepared by compounding nanoscale titanium dioxide and a porous organic carrier. The environment-friendly 'green and environment-friendly' water-based coating liquid without containing an organic solvent is adopted, the main raw material adopts the water-resistant and chemical-resistant acrylic resin, and the dispersed silica sol is combined to form a relatively uniform and compact film layer, so that the finally obtained coating has a relatively strong ultraviolet protection effect, and also has relatively strong adhesive force, wear resistance and light transmission performance to other visible light.

Description

Technical field [0001] The present invention relates to the field of optical lens coated liquid, and more particularly to an ultraviolet shield nano-coated liquid and its application on optical lenses. Background technique [0002] UV rays in the sun, because the ultraviolet wavelength is very short, the energy is quite high, its destructive power is very large, in recent years, UV lines have increasingly caused people's attention. The damage of ultraviolet rays to human eyes mainly depends on the wavelength of ultraviolet light, radiation time, radiation intensity, and human eye itself. The cornea of ​​the human eye is the most commonly subject to the eye tissue of ultraviolet injury, such as the frequently seen the eye disease associated with the niche, and the selection, the seaside, beach in high latitudes, beach, beach , Snow, plateau, asphalt road and other light reflections, ultraviolet rays every moment affecting human health, especially damage to the eyes. [0003] Wear ...
