Problems solved by technology

[0004] In the existing building decoration materials such as wall tiles, there are few reports on ceramic glazes with good uniformity and stable antibacterial function. If antibacterial agents are simply added, the antibacterial stability will be weakened due to the high temperature melting process, and even May lose antimicrobial effect

Abstract

The invention discloses antibacterial ceramic glaze and a preparation method thereof. The preparation method comprises the following steps: firstly, preparing antibacterial glaze slip, and then glazing and sintering to obtain the antibacterial ceramic glaze. The preparation method of the antibacterial glaze slip comprises the following steps: mixing the following materials in percentage by mass: 25 to 35 percent of low temperature frit, 30 to 40 percent of potassium feldspar, 10 to 20 percent of quartz, 3 to 6 percent of calcite, 3 to 6 percent oftalc, 2 to 5 percent of calcium phosphate, 1 to 5 percent of kaolin and 5 to 10 percent of calcined clay to obtain mixed powder; adding antibacterial powder into mixed powder, and uniformly mixing, wherein the adding amount of the antibacterial powder is 0.1 to 1 percent of the mass of the mixed powder; finely grinding to be 300 to 350 meshes, then adding water to obtain the glaze slip, and regulating the specific weight of the glaze slip to be 1.6 to 1.7g / cm<3>, thus obtaining the antibacterial ceramic glaze. Compared with existing ceramic glaze, the ceramic glaze prepared by the preparation method disclosed by the invention is scientific in material burdening, reasonable in preparation and stable in performance; in addition, the antibacterial ceramic glaze does not contain extremely toxic substances such as lead and cadmium; meanwhile, the antibacterial ceramic glaze also has uniform and persistent antibacterial characteristic, and further the application range of the ceramic glaze is widened.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to an antibacterial ceramic glaze and a preparation method thereof. Background technique [0002] Bacteria and mold, as pathogenic bacteria, are very harmful to humans, animals and plants, affecting people's health and even life-threatening, and bringing significant economic losses. Therefore, the research on antibacterial materials and their products has attracted people's attention day by day, and the demand for antibacterial products will constitute a huge market. [0003] Wall tiles, no matter for home interior decoration, industrial production or public places, how to make them have more functions related to people's health protection in addition to satisfying the appearance and practicality is also a benchmark for scientific researchers in the industry to follow the trend of the times and life and made thinking. [0004] Among the existing building decoration materials such...
