Problems solved by technology

Existing ceramic materials are generally single-function products, that is, one product does not have multiple functions, which greatly limits its application range. Although there are also two functional agents used for matching, the effect is still unsatisfactory, and further research is needed. improve

Abstract

The invention discloses a photo chromic ceramic glaze and a preparation method thereof. The preparation method comprises the steps of preparation of photo chromic glaze, glazing, sintering of ceramic glaze, wherein the method for preparing photo chromic glaze comprises the steps of preparing the mixed powder, by mass, mixed with 25-35% of low temperature frit, 30-40% of potash feldspar, 10-20% of quartz, 3-6% of calcite, 3-6% of speck stone, 2-5% of calcium orthophosphate, 1-5% of kaolin, 5-10% of calcined clay, adding the function agent into the mixed powder and uniform mixing. The addition of the function agent is 1-8% of the mass of the mixed powder. The glaze is prepared by fine grinding and water adding, so that the photo chromic ceramic glaze is obtained. Compared with the existing ceramic glaze, the ceramic glaze of the invention has the advantages of scientific ingredients, reasonable preparation, stable performance, without toxic substances such as lead and cadmium. The ceramic glaze also has the advantages of antibacterial properties of uniform persistent spectrum, air purification and photo chromic function, thereby further broadening the scope of application of ceramic glaze.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a photochromic 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 a...
