Abstract

The invention relates to an ultraviolet shielding nano-coating solution, wherein the ultraviolet shielding nano-coating solution is calculated according to parts by weight and consists of the following components: 40-60 parts of acrylic resin, 10-25 parts of dispersed silica sol, and 3-25 parts of ultraviolet shielding agent 8 parts, 1-5 parts of silane coupling agent, 0.05-8 parts of auxiliary agent and 20-50 parts of water; among them, the ultraviolet shielding agent is TiO2 prepared by compounding nano-scale titanium dioxide and porous organic carrier 2 / porous organic carrier composite. Among them, the present invention uses an environmentally friendly "green" water-based coating solution that does not contain organic solvents. The main raw material is water-resistant and chemical-resistant acrylic resin. Combined with dispersed silica sol, a relatively uniform and dense film can be formed. Finally The obtained coating film not only has strong ultraviolet protection effect, but also has strong adhesion, wear resistance and light transmission performance to other visible light.

Description

technical field [0001] The invention relates to the field of optical lens coating liquid, in particular to an ultraviolet shielding nano coating liquid and its application on optical lens. Background technique [0002] Ultraviolet rays in sunlight, because the wavelength of ultraviolet rays is very short and the energy is quite high, it has great destructive power. In recent years, the damage of ultraviolet rays to human eyes has attracted more and more attention. The damage of ultraviolet rays to the human eye mainly depends on the wavelength of ultraviolet rays, radiation time, radiation intensity and the defense mechanism and ability of the human eye itself. The cornea and lens of the human eye are the eye tissues that are most often damaged by ultraviolet rays, such as common solar keratitis, corneal endothelial damage, solar cataract and other related eye diseases. In areas with strong light reflection, such as snow, plateaus, and asphalt roads, ultraviolet rays are af...
