Abstract

The invention relates to glaze composition prepared from manganese tungstate as an active material and having a photocatalytic function and a preparation method of the glaze composition. The glaze composition is prepared from powder A, MnWO4 and kaolin, wherein the mass percentage of the powder A, MnWO4 and kaolin is (84%-88%): (4%-8%): (6%-10%); the powder A comprises raw materials by weight as follows: 20%-30% of SiO2, 5%-10% of Al2O3, 40%-50% of P2O5, 1.5%-2.5% of MnO, 12%-14% of Li2O, 6%-8% of Na2O and 12%-13% of K2O. The glaze composition contains the powder A as a main component, contains an appropriate amount of MnWO4, and has an excellent photocatalytic function on the basis of a good glaze effect.

Description

technical field

[0001] The invention belongs to the technical field of ceramic glazes, and relates to a surface glaze for architectural sanitary ceramics and a preparation method thereof, in particular to a photocatalytic function MnWO 4 Crystalline glaze and a preparation method thereof. The surface of the glaze prepared by the method has an excellent function of photocatalytically degrading poisonous gas, and at the same time has a good decorative effect and a strong covering ability. And under the condition of sunlight, it can effectively decompose toxic gases in the air such as benzene, sulfur dioxide, formaldehyde, etc., which is of great significance to the purification of the home environment. Background technique

[0002] At present, in the face of overcapacity in the traditional building ceramics industry and the gradual narrowing of the market, the surface functionalization of ceramic materials is an important development direction for enhancing the value of tradit...

Examples

preparation example Construction

[0039] 1. The method for preparing the glaze proposed by the present invention is simple to operate, and the prepared glaze layer has a good decorative effect on the surface, presents dark green color, beautiful color, strong covering ability, and the glaze surface is flat, smooth, and free of defects such as pinholes;

[0040] 2. The glaze prepared by the present invention has a photocatalytic function, and the ceramic glaze can be decomposed to toxic dyes such as phenolphthalein red after 5 hours under light conditions. The decomposition rate of phenolphthalein can reach more than 75%. It plays an obvious role in promoting the purification of the home environment, and is of great significance to improving the quality of the environment and improving people's living standards.
