Problems solved by technology

However, the preparation process of the above-mentioned antibacterial powder is complicated, the cost is high, and it is not resistant to high temperature, so it is not suitable for preparing antibacterial tiles.
In addition, some antibacterial powders will choose to be mixed with rare earth compounds, which will produce radiation to the human body while realizing the antibacterial function, which will seriously damage human health. These problems seriously limit the development of antibacterial tiles. High temperature resistant antibacterial powder for glaze

Abstract

The invention discloses a glass ceramic antibacterial powder and a preparation method and application thereof. The invention relates to the technical field of antibacterial materials, in particular to a glass ceramic antibacterial powder and a preparation method and application thereof. The method includes: weighing and mixing raw materials to obtain a first mixture; mixing the first mixture with a dispersion liquid to obtain a first slurry; grinding, drying, and powdering the first slurry to obtain a first powder ; The first powder is melted at high temperature to obtain a first glass body; the first glass body is heated and crystallized, and then crushed, ground, and sieved to obtain a finished product. The preparation method has the advantages of simple process, low cost and large output, and the obtained powder particles have no agglomeration and good filling performance. Correspondingly, the prepared glass-ceramic antibacterial powder has good high temperature resistance and stable antibacterial performance, and can be added to ceramic glazes as an antibacterial agent.

Description

technical field [0001] The invention relates to the technical field of antibacterial materials, in particular to a glass ceramic antibacterial powder and its preparation method and application. Background technique [0002] Consumers have higher and higher demands on ceramics with antibacterial function. In the ceramic industry, antibacterial powder is often added to achieve the antibacterial function of ceramics. Most of the antibacterial powders currently used in antibacterial ceramics are Ag loaded on porous materials. + , Zn + and Cu 2+ , or doped TiO 2 , rare earth compounds, etc. For example, Chinese invention patent CN 110547302 B discloses an antibacterial powder and its preparation method and application. The antibacterial powder uses silicon oxide as a carrier and supports silver-copper-zinc composite metal elements. The basic particle size of the antibacterial powder is less than 10um, the cost is low, the antibacterial performance is superior, and it contain...
