Abstract

The invention discloses a glass self-cleaning liquid and self-cleaning glass and a preparation method thereof. The glass self-cleaning liquid comprises the following ingredients (by weight): 100-300 parts of SiO2 sol, 1-5 parts of ethyl orthosilicate, 1-10 parts of ammonia water, 50-300 parts of polyethylene glycol, 10-50 parts of n-butanol, 0.1-0.5 part of PVPK30, 0.5-2.0 parts of Dipropylene glycol mono butyl ether, and 10-50 parts of water glass. The self-cleaning glass prepared by the use of the self-cleaning liquid has a good self-cleaning effect and also has good weatherability and lighttransmittance. In addition, usability of the glass is enhanced.

Description

technical field [0001] The invention relates to the technical field of self-cleaning glass preparation, in particular to a glass self-cleaning liquid, self-cleaning glass and a preparation method thereof. Background technique [0002] With the large-scale application of glass curtain walls, glass roofs, and glass windows in high-rise buildings, the problem of glass cleaning has become increasingly prominent, and the problem of environmental pollution has become increasingly serious, causing a large amount of dust to adhere to the glass surface, which not only affects the beauty of the glass, but also seriously affects the quality of the glass. light transmittance. At present, glass is mostly cleaned by scrubbing, but for tall architectural glass, scrubbing is expensive, difficult and dangerous. Therefore, it is particularly important to find a glass with self-cleaning function. The existing self-cleaning glass is mainly TiO 2 Similar to self-cleaning glass, there are probl...
