Abstract

The invention provides a photocatalyst additive and an application method of hydrophilic coating containing the additive. The invention discloses the photocatalyst additive which is used for the hydrophilic coating; the photocatalyst coating is nano titanium dioxide TiO2 doped with cobalt Co, iron Fe, nitrogen N and sulfur S. The hydrophilic coating containing the photocatalyst additive has an excellent toluene removing effect; furthermore, the invention further provides the application method of the hydrophilic coating added with the photocatalyst additive; coating thicknesses corresponding to aluminum foils with different thicknesses are given when the hydrophilic coating is used for aluminum fins of an air conditioner.

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 toluene, deodorizing, anti-pollution, and air purification. 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 irradiation ...
