Abstract

The invention relates to the technical field of ceramics and functional decorative materials, in particular to a photocatalytic negative ion ceramic tile containing a modified porous material and a preparation process of the ceramic tile. The ceramic tile comprises a ceramic tile blank and cover glaze, raw materials of the cover glaze comprise a composite porous photocatalytic suspension and a base material, wherein the composite porous photocatalytic suspension accounts for 40-50 wt% of the weight of the base material, the composite porous photocatalytic suspension is prepared from the following raw materials: a porous material, elbaite, nano magnesium oxide, bismuth vanadate, nano zinc oxide and calcium oxide, the porous material is prepared from zeolite and diatomite, and the particle sizes of the elbaite, the nano magnesium oxide, the bismuth vanadate, the nano zinc oxide and the calcium oxide are all smaller than the pore diameters of micropores of the porous material. The prepared photocatalytic negative ion ceramic tile cover glaze contains a porous material, micropores of the porous material can absorb harmful gas in air, and harmful gas is purified through negative ions, photocatalysis, far infrared rays and other materials.

Description

Technical field[0001]The invention relates to the technical field of ceramics and functional decorative materials, in particular to a photocatalytic anion ceramic tile containing modified porous materials and a preparation process thereof.Background technique[0002]With the development of industry, air pollution has become more and more serious, and the air contains various substances harmful to the human body. Therefore, air purification has attracted more and more attention.[0003]In recent years, many indoor decoration materials for purifying air have emerged in the domestic and foreign markets, such as negative ion coatings, negative ion plates, negative ion tiles, photocatalytic coatings and photocatalytic tiles.[0004]There are two types of anion tiles on the market. One is to introduce rare earth composite salts into the ceramic glaze layer; the other is that the surface of the ceramic tile is coated with a photocatalyst coating.[0005]At present, the negative ion tiles produced ...
