Problems solved by technology

Antibacterial sanitary ceramic products are more and more widely used in people's lives. In order to make up for the vacancy of antibacterial sanitary ceramics in the market for healthy and environmentally friendly homes, some manufacturers of antibacterial sanitary ceramics try to add silver ions to antibacterial sanitary ceramic glazes. Antibacterial, but the antibacterial rate of general silver ion antibacterial materials is only about 95%, and the durability of silver ion antibacterial agents is not good, and the antibacterial effect is lower than 85% after half a year, and the antibacterial effect of antibacterial sanitary ceramics using it is poor

Abstract

The invention discloses an antibacterial glaze, which is composed of a bottom glaze and a surface glaze; the composition of the bottom glaze is 7-12wt% of zirconium silicate, 1-2wt% of titanium dioxide, and the balance is the basic bottom glaze; The composition of the glaze is 0.5-2wt% of rare earth inorganic compound and the rest is basic surface glaze. The rare earth inorganic compound contains titanium dioxide with a content of ≥16wt% and thorium dioxide with a content of ≥15wt%. In addition, the preparation method and application of the antibacterial glaze are also disclosed. The invention obtains a glaze layer capable of radiating far-infrared rays through formula design, so that the sanitary ceramic products have antibacterial and antibacterial effects, thereby effectively improving the antibacterial effect of the antibacterial sanitary ceramics, and better solving the problems of environment optimization and purification.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to an antibacterial glaze and its preparation method and application. Background technique [0002] With the improvement of people's living standards and quality of life, people pay more and more attention to the environment optimization and purification of public places, living spaces, daily life and hospital facilities. Antibacterial sanitary ceramic products are more and more widely used in people's lives. In order to make up for the vacancy of antibacterial sanitary ceramics in the market for healthy and environmentally friendly homes, some manufacturers of antibacterial sanitary ceramics try to add silver ions to antibacterial sanitary ceramic glazes. Antibacterial, but the antibacterial rate of general silver ion antibacterial materials is only about 95%, and the persistence of silver ion antibacterial agents is not good, and the antibacterial effect is lower than 85% a...
