Problems solved by technology

With the increase of skin diseases, people are more and more afraid of ultraviolet rays, and their defense awareness has gradually improved, so the demand for anti-ultraviolet coatings is also increasing, but the anti-ultraviolet coatings on the market have stable performance. Poor, if it is used for a long time, it will decompose and volatilize with the absorber molecules, resulting in a decrease in the anti-ultraviolet ability, and it is difficult to maintain the anti-ultraviolet ability for a long time. Therefore, the anti-ultraviolet coating needs to be improved.

Abstract

The invention relates to the technical field of coating, in particular to anti-ultraviolet coating. The anti-ultraviolet coating is prepared from the following raw materials in part by weight: 40-55 parts of epoxy acrylic resin, 12-23 parts of water glass, 7-13 parts of modified nanometer titanium dioxide, 3-9 parts of nano-ceramic powder, 4-7 parts of polyoxyethylene laurate, 9-16 parts of propylene glycol methyl ether acetate, 1.5-3.5 parts of perchlorovinyl resin, 2-4.5 parts of a film-forming agent, 3-5 parts of calcium carbonate, 0.5-1.8 parts of a fire retardant, and 1-2 parts of a dispersant. The anti-ultraviolet coating has the excellent anti-ultraviolet performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-ultraviolet coating. Background technique [0002] Ultraviolet light is an electromagnetic wave with a wavelength smaller than visible light. Most of the ultraviolet light on the earth's surface comes from the sun. Ultraviolet light is a kind of harmful light. It is absorbed through the skin and can damage DNA. When DNA is damaged, cells will die or develop into Uncontrollable cancer cells, this is the initial stage of tumor formation. With the increase of skin diseases, people are more and more afraid of ultraviolet rays, and their defense awareness has gradually improved, so the demand for anti-ultraviolet coatings is also increasing, but the anti-ultraviolet coatings on the market have stable performance. Poor, if it is used for a long time, it will decompose and volatilize with the absorber molecules, resulting in a decrease in the anti-ultraviolet ability, and it i...
