Preparation process of photocatalyst self-cleaning material

Abstract

The invention discloses a preparation process of a photocatalyst self-cleaning material, and relates to the field of photocatalysts. The invention aims at solving the problems that in the prior art, existing titanium dioxide particles are prone to agglomeration, poor in dispersity, common in treatment capacity, prone to falling off and free of long-term working capacity. The preparation method comprises the following steps: S1, heating and drying titanium dioxide crystals; S2, firing the dried titanium dioxide crystal, and adding zirconium dioxide in the firing process; S3, washing the fired raw materials with cooling water, and then standing and drying; S4, vibrating and mixing the dried raw materials and zinc oxide, and after mixing, grinding through a grinding machine; S5, mixing and stirring the ground powder and a precipitator, and adding a titaniferous solution in the mixing process; S6, heating the mixture at a high temperature to 100-200 DEG C; S7, after the mixture is dried and cooled, performing nano cutting; and S8, after cutting, stirring, mixing and bonding through an adhesive to prepare the photocatalyst self-cleaning material.

Description

technical field [0001] The invention relates to the technical field of photocatalysts, in particular to a preparation process of photocatalyst self-cleaning materials. Background technique [0002] Photocatalyst is a general term for a photo-semiconductor material with photocatalytic function represented by nano-scale titanium dioxide. It is coated on the surface of the substrate and has a strong catalytic degradation function under the action of ultraviolet light and visible light: it can effectively degrade air. Toxic and harmful gases; can effectively kill a variety of bacteria, and can decompose and harmless 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 materials mainly include nano-TiO2, ZnO, CdS, WO3, Fe2O3, PbS, SnO2, ZnS, SrTiO3, SiO2, etc. Since 2000, some nano-noble metals (platinum, rhodium, palladium, etc.) have been found to have better...
