Problems solved by technology

[0002] In recent years, people have paid more and more attention to the importance of antibacterial disinfection, which has given birth to a variety of disinfection products. People have raised their awareness of hygiene and realized the importance of antibacterial disinfection. The demand for ceramic products is also increasing. Most of the ceramic products with antibacterial function adopt the technical scheme of adding antibacterial agents to the glaze. Most of the antibacterial agents are not on the surface of ceramic products, and the antibacterial effect is poor. Another One solution is to cover a layer of antibacterial layer on the surface of ceramic products. The antibacterial layer is easy to wear during daily use, and it cannot achieve long-term antibacterial performance.

Abstract

The invention discloses a ceramic product with an antibacterial function and a preparation method thereof. The ceramic product is sequentially provided with an antibacterial layer, a glaze layer and a green brick layer from top to bottom. The antibacterial layer is polymer silver ions. According to the prepared ceramic product with the antibacterial function, good sterilization and disinfection performance is achieved by arranging the polymer silver ion antibacterial layer with the particle size being 2-5 nm, a polymer silver ion complexing system is stable, the antibacterial layer and the glaze surface are tightly combined in the firing process, the preparation method is simple, the antibacterial effect is improved while the using amount of the silver ion antibacterial agent is saved, the production cost is reduced, the antibacterial layer is not prone to being rubbed off in the using process, and the long-acting, rapid and broad-spectrum sterilization purpose is achieved.
