Problems solved by technology

[0003] In the prior art, ceramic glazes have been improved for this point. For example, antibacterial effects are achieved by adding elements with bactericidal functions such as silver and titanium to ceramics and ceramic glazes respectively, but ceramic products such as tiles are prone to use. In the process, it is easy to gradually fall off with the extension of time and lose the antibacterial function. There are problems that the antibacterial performance is unstable and difficult to last, and it is impossible to achieve both antibacterial and anti-mildew effects

Abstract

The invention belongs to the technical field of ceramics, and discloses a ceramic glaze with antibacterial and mildew-proof effects. Feldspar, alkaline earth metal carbonate, nano-silver, yttrium oxide, an antibacterial agent and sodium hexametaphosphate are effectively proportioned, all the components are compounded to achieve a synergistic effect, the obtained ceramic glaze is high in effectivecomponent content, and a nanoscale antibacterial agent can be uniformly distributed in a ceramic glaze layer matrix after the ceramic glaze is glazed, dried and sintered, so that a ceramic glaze layerhas relatively strong antibacterial performance and a remarkable antibacterial effect. The invention also discloses a preparation method of the ceramic glaze. A specific inorganic antibacterial agentand a specific organic antibacterial agent are compounded; in the compounded antibacterial agent, the organic antibacterial agent part and the inorganic antibacterial agent part cooperate with each other and influence each other, the antibacterial performance of the organic antibacterial agent part and the inorganic antibacterial agent part is enhanced; the antibacterial performance is enhanced under the synergistic effect of the organic antibacterial agent part and the inorganic antibacterial agent part, the antibacterial performance is stable, and the invention is a ceramic glaze with long-acting antibacterial and mildew-proof effects.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a ceramic glaze with antibacterial and antimildew effects and a preparation method and application thereof. Background technique [0002] Ceramic tiles are an important class of ceramic products. They are mainly architectural or decorative materials obtained by grinding, mixing, pressing, glazing, sintering and other processes of metal oxides and semi-metal oxides. They are used in hospitals, restaurants and other places and households. In kitchens, bathrooms and other occasions, especially after the "return to the south" in the south, traditional tiles are prone to mold and have poor antibacterial effects, which will endanger human health in the long run. Therefore, people are not satisfied with the general functions such as attractive in appearance and durable of traditional ceramic products, and hope to have functions such as sterilization, disinfection and deodor...
