Abstract

The invention relates to UV-resistant wear-resistant glass and belongs to the technical field of glass. The UV-resistant wear-resistant glass comprises a glass base. The surface of the glass base is provided with an anti-UV coating. The anti-UV coating is prepared from 15-30wt% of aqueous polyurethane resin, 1-5wt% of polytetrafluoroethylene, 1-3wt% of a hydroxyphenylbenzotriazole-type UV absorbent, 1-5wt% of disodium methylene dinaphthalenesulfonate, 0.1-2wt% of a sorbitan ester emulsifier, 0.02-1wt% of an organic tin drier, 0.01-1wt% of an aminopropylsilane coupling agent and 53-82wt% of water. The organic tin drier is dibutyltin dilaurate. The UV-resistant wear-resistant glass has good wear and corrosion resistance and can effectively prevent UV erosion.

Description

technical field [0001] The invention relates to an ultraviolet wear-resistant glass, which belongs to the technical field of glass. Background technique [0002] In recent years, due to the massive discharge of halogen-containing compounds such as Freon, the ozone layer has been increasingly damaged. Appropriate ultraviolet radiation is beneficial to the human body, but excessive ultraviolet radiation is very harmful to the human body. It can cause skin erythema or sunburn, pigmentation, skin aging and even skin cancer. Therefore, protection against ultraviolet radiation has received widespread attention. Most of the glass currently used by people is single-layer flat glass, which has good light transmission, but this glass cannot prevent the erosion of ultraviolet rays. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a UV wear-resistant glass, which has good wear resistance and corrosion resista...
