High-temperature environment-friendly antibacterial glaze

Abstract

The invention mainly relates to the technical field of ceramic glaze processing, and discloses a high-temperature environment-friendly antibacterial glaze. The high-temperature environment-friendly antibacterial glaze is prepared from the following raw materials: silicon dioxide, zinc oxide, iron nitride, aluminum oxide, niobium pentoxide, vanadium boride, tantalum pentoxide, hafnium oxide, table salt and an antibacterial agent. A ceramic product keeps the original color and luster after being subjected to short-time high-temperature burning, the production cost is lowered by 13.1 percent, and the antibacterial rate is up to 67.4 percent; the ceramic product is safe, environment-friendly and healthy, and no lead or cadmium is dissolved out; the antibacterial agent is abundant in raw materials, has a high antibacterial rate, high heat resistance and high stability, and has antibacterial time being up to 9 years when being used normally; the raw materials are subjected to repeated melting, quenching and ball milling after being subjected to ball milling, the table salt is added after primary quenching, and the antibacterial agent is added after secondary melting, so that the fineness and fluidity of the glaze are improved, an expansion coefficient is matched, and the glaze is smooth; the antibacterial agent is added at a low temperature, and short-time high-temperature treatment is performed, so that the influence on the color and luster of the ceramic product can be avoided, and the antibacterial life can be prolonged.

Description

technical field [0001] The invention mainly relates to the technical field of ceramic glaze processing, in particular to a high-temperature environment-friendly antibacterial glaze. Background technique [0002] At present, ceramic glazes are generally fired at high temperatures. The temperature is higher than 1250°C, and some are even above 1400°C. It accounts for more than 30%, and most of the ceramic glazes are filled with lead, which will cause great harm to the human body during preparation and use. Therefore, reducing energy consumption during high-temperature firing is an urgent need at present. [0003] With the progress of society and the improvement of people's living standards, controlling and eliminating the growth and reproduction of harmful bacteria has become an important topic in the field of scientific research, and has attracted more and more people's attention, becoming an important part of environmental protection materials. The research and development ...

Problems solved by technology

[0002] At present, ceramic glazes are generally fired at high temperatures. The temperature is higher than 1250 ° C, and some are even above 1400 ° C. The energy cost of firing accounts for a large proportion of the production cost. Foreign countries account for 20-30%, while my country It accounts for more than 30%, and most of the ceramic glazes are filled with lead, which will cause great harm to the human body in the process of preparation and use. Therefore, reducing energy consumption during high-temperature firing is an urgent need at present.

[0003] With the progress of society and the improvement of people's living standards, controlling and eliminating the growth and reproduction of harmful bacteria has become an important topic in the field of scientific research, and has attracted more and more people's attention, and has become an important part of environmental protection materials. The research and development of antibacterial agents and antibacterial ceramics is still in its infancy
