Abstract

The invention discloses a photocatalyst additive used for a hydrophilic coating. The photocatalyst additive is nanometer titanium dioxide TiO2 doped with Ce, Cu, N and S. The hydrophilic coating containing the photocatalyst additive has an excellent anti-microbial effect. Besides, the invention also provides a use method for the hydrophilic coating containing the photocatalyst additive. The coating thickness corresponding to aluminum foils in different thicknesses is given out when the additive is applied to an air conditioner aluminum fin.

Description

technical field [0001] The invention relates to the technical field of coating materials, in particular to a method for using a photocatalyst additive and a hydrophilic coating containing the additive. Background technique [0002] Photocatalyst is a nano-titanium dioxide (TiO 2 ) is a general term for photo-semiconductor materials with photocatalytic function. It is coated on the surface of the substrate, and under the action of ultraviolet light, it produces a strong catalytic degradation function: it can effectively degrade toxic and harmful gases in the air; it can effectively kill A variety of bacteria, and can decompose and harmlessly treat the toxins released by bacteria or fungi; at the same time, it also has the functions of removing formaldehyde, deodorizing, anti-pollution, and purifying air. Photocatalyst technology was discovered in 1967 by Professor Kenichi Honda and then graduate student Akira Fujishima of the University of Tokyo in 1967. Under the irradiatio...
