Embodiment 1

[0033] A. Preparation of composite antibacterial powder

[0034] Preparation of silver molybdate powder: Silver nitrate and ammonium molybdate were added to deionized water at a molar ratio of 2:1 to prepare silver nitrate solution and ammonium molybdate solution, and the above two solutions were mixed and stirred in the reactor for 10 minutes. Then heat the reaction in a microwave oven with a power of 800W for 3 minutes, wash the obtained pale yellow precipitate with distilled water, filter, and dry at a constant temperature of 60°C for 10 hours to obtain silver molybdate powder with a particle size of 2 μm;

[0035] Preparation of zinc molybdate powder: add zinc nitrate and ammonium molybdate into deionized water at a molar ratio of 1:1.2 to prepare zinc nitrate solution and ammonium molybdate solution, and then slowly add the zinc nitrate solution to the ammonium molybdate solution , stirred for 20 minutes, the resulting white precipitate was washed with distilled water, fi...

Abstract

The invention belongs to the technical field of ceramics, and relates to an antibacterial sanitary ceramic glaze and a preparation method. The antibacterial sanitary ceramic glaze is prepared from the following raw materials: potash feldspar, sandstone, dolomite, limestone, zircon powder, frit, aluminum oxide, zinc oxide, Suzhou clay, zirconium iron pink, praseodymium yellow, cellulose and compound antibacterial powder; the composite antibacterial powder is prepared from the following raw materials in percentage by mass: 15 to 20 percent of silver molybdate, 60 to 65 percent of zinc molybdate and 20 to 25 percent of titanium dioxide. The preparation method of the antibacterial sanitary ceramic glaze comprises the following steps of A, preparation of the composite antibacterial powder; B, preparation of glaze slip; C, preparation of the antibacterial sanitary ceramic glaze. The preparation method provided by the invention is simple and is easy to operate; the antibacterial sanitary ceramic glaze is resistant to a high temperature, does not discolor, and is excellent in antibacterial property.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to an antibacterial sanitary ceramic glaze and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental protection awareness, people pay more and more attention to the impact of daily necessities around them on their own health. And family kitchens, toilets, especially sanitary ceramic products in hospitals and public places are prone to breed bacteria and affect people's health. Antibacterial sanitary ceramics is a new type of functional material that protects the environment. It combines antibacterial technology with ceramic materials. It not only maintains the original use function, decorative effect and physical and chemical properties of ceramic products, but also increases antibacterial, sterilizing and self-cleaning. It can be widely used in health, medical, family room and...
