Abstract

The invention relates to self-cleaning coating, in particular to self-cleaning coating for aluminum alloy doors and windows. The self-cleaning coating for the aluminum alloy doors and windows is prepared from the following raw materials including, by weight, 20-30 parts of phenyltrimethoxysilane, 25-40 parts of methyl-ethyloxy silicone oil, 10-15 parts of fluorosilicone, 15-20 parts of methyl glyoxylate, 1-5 parts of oxalic acid, 0.1-0.5 part of cyclopentanol and 0.3-0.7 part of catalysts. According to the self-cleaning coating for the aluminum alloy doors and windows, material stability is good, adhesive force is strong, and the service life is long.

Description

technical field [0001] The invention relates to a self-cleaning paint, especially a self-cleaning paint for aluminum alloy doors and windows. Background technique [0002] Glass self-cleaning will be an important market for modern household hygiene needs. The traditional method of glass self-cleaning spraying construction is spraying. Its loss, equipment purchase, and operation difficulty are difficult for families to accept. We are looking for a convenient construction. Material saving, low-cost glass self-cleaning construction method is very necessary. [0003] Developing a transparent self-cleaning paint that can be applied to the glass surface to make the glass surface appear self-cleaning function is the pursuit goal of people in recent years. Most of the glass self-cleaning coatings available in the market are hydrophilic, and the TiO covered 2 Under the excitation of ultraviolet rays, the coating exhibits hydrophilicity and photolysis, so it can decompose and peel o...
