Therefore, in an indoor environment without additional artificial ultraviolet rays, the bactericidal effect is completely useless
[0008] 3. Although some people try to combine the above two types of materials, or add rare earth, far-infrared and other elements for modification, but due to the restriction of their mechanism of action, the improvement of bactericidal ability is limited, especially for the resistance to bacteria commonly found in hospital environments. drug bacteria, helpless

Embodiment 1

[0032] A ceramic or enamel sterilizing glaze material, which includes components and their weight percentages: 80% of ceramic glaze stock solution, 15% of silver powder, and 5% of copper oxide powder. The purity of the silver powder is not less than 99.99%. The particle size of the silver powder is 500 mesh, and the particle size of the copper oxide powder is 500 mesh. The above materials are mixed and ground by a high-speed ball mill for 30 hours, so that the powder particles are smaller than 200nm, and silver-copper oxide composite glazes for ceramic or enamel sterilization glaze materials are prepared.

[0033] When the silver-copper oxide composite glaze obtained above is applied to the ceramic surface as a surface glaze, the ordinary ceramic liquid glaze is used as a primer glaze, and the silver-copper oxide composite glaze obtained above is used as a surface glaze to cover, It is sintered at 1200°C and melted on the surface of ceramic products to form a dense glaze of s...

Abstract

The invention provides a ceramic or enamel sterilization glaze material and a preparation method and application thereof. The ceramic or enamel sterilization glaze material is prepared from, by weight, 80-90% of ceramic or enamel glaze materials, 5-15% of silver powder and 5-15% of copper oxide powder or zinc oxide powder. By the adoption of the technical scheme, the surface of a ceramic or enamel product has the excellent sterilization and mould-proof ability, and the sterilization effect is kept synchronous with the service life of the ceramic or enamel product; the material components are environmentally friendly, and using safety of the ceramic or enamel product is ensured.

Description

technical field [0001] The invention belongs to the technical field of ceramic sterilization materials, and in particular relates to a ceramic or enamel sterilization glaze material, a preparation method and an application thereof. Background technique [0002] Antibacterial ceramic products mainly add inorganic antibacterial agents to ceramic glazes, which are sintered at high temperatures to form antibacterial glazes, which have antibacterial properties. At present, the commonly used inorganic antibacterial agents are mainly divided into two types: [0003] 1. Silver ion antibacterial agent. Its antibacterial mechanism is to slowly release a small amount of silver ion Ag through the silver compound. + , into the interior of the bacteria, leading to bacterial death. At the same time, the catalytic action of silver ions decomposes oxygen into active oxygen O to kill bacteria. [0004] 2. Nano titanium dioxide TiO 2 (photocatalyst). Its antibacterial mechanism is that b...
