Abstract

The invention discloses a coating composition coated on glass surfaces. The coating composition comprises 10-80wt% of nano slurry, 20-80wt% of film-forming substance, 0-50wt% of solvent and 0.1-1wt% of auxiliaries. The coating composition is used for preparing coated glass and has the advantages of capability of reducing light pollution and possessing low manufacturing cost.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a coating composition for coating glass surfaces and a preparation method thereof. Background technique [0002] The outer surface of a building is generally installed with a glass curtain wall. The glass curtain wall produces light reflection under strong light. Due to the high reflectivity of light, the light irradiates the human body, especially the eyes, and damages the human visual nervous system. . When the light shines on the office, people work and live under strong light for a long time, which will make people dizzy and affect the visual nervous system of people. [0003] When the light shines on the driver's eyes through the car glass, the driver can't see the road conditions ahead, which is easy to cause traffic accidents. In order to reduce the reflectivity of glass, a coating composition is generally applied to the surface of the glass. In the prior art, the reflectance o...
