Abstract

The invention relates to a WP2O7 crystalline glaze composition with a photocatalysis function and a preparation method thereof. The WP2O7 crystalline glaze composition is prepared from the following constituents by mass percent: 84% to 88% of powder material A, 7% to 9% of WP2O7 and 5% to 7% of kaolin, wherein the chemical composition mass ratio of SiO2 to Al2O3 to P2O5 to MgO to Li2O to Na2O to K2O of the powder material A is (10 to 14) to (3 to 5) to (45 to 49) to (1 to 3) to (8 to 12) to (8 to 12) to (4 to 6). The WP2O7 crystalline glaze composition has the advantages that the WP2O7 is introduced into the preparation of the glaze for the first time, not only is the decorative effect on the obtained glaze layer surface crystallization good, but also the performance in photocatalysis degradation on toxic gas and organic pollutant is excellent.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and relates to a method for preparing a glaze on the surface of architectural sanitary ceramics, in particular to a WP with photocatalytic function 2 o 7 A method for preparing a crystalline ceramic glaze. The surface of the glaze prepared by the method has an excellent photocatalytic degradation function, and at the same time has a good decorative effect of crystal flowers, and can effectively decompose organic pollutants adsorbed on the surface under sunlight conditions. It is of great significance to purify the home environment. Background technique [0002] In the process of home decoration and decoration, various toxic organic substances in the home environment produced by chemical products such as coatings are increasing, which has a great impact on human health. According to reports, there are more than 1,000 acute and chronic poisoning incidents caused by home decoration alone...
