Abstract

The invention discloses a colorless and transparent coating with anti-microbial and self-cleaning function. The coating comprises, by weight, 10-20 parts of tetraethoxysilane, 10-20 parts of water, 40-80 parts of isopropanol, 8-15 parts of ethylene glycol monomethyl ether, 0.05-3 parts of phosphoric acid, 1-5 parts of a water-repellent polymer, 0.1-0.3 parts of a colorless and transparent nanosilver aqueous solution. The coating has advantages of good transparency, strong adhesion, good water repellency and good self-cleaning, wide spectrum sterilizing, and is applicable for the field of surfaces of various decorative material, sanitary appliances, glasses for a shower room and building glasses. In addition, the invention further discloses a preparation method for the colorless and transparent coating with anti-microbial and self-cleaning function.

Description

technical field [0001] The invention relates to a nanocomposite coating, in particular to a colorless and transparent antibacterial self-cleaning coating which can be used for painting the surfaces of various decorative materials and glass surfaces; the invention also relates to a preparation method of the colorless and transparent antibacterial self-cleaning coating.
