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 the original liquid of ceramic glaze, 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 for 30 hours with a high-speed ball mill, so that the powder particles are smaller than 200 nm, and a ceramic or enamel sterilization glaze material silver copper oxide composite glaze is prepared.

[0033] When applying the silver-copper oxide composite glaze obtained above to the ceramic surface as a top glaze, first apply the ordinary ceramic stock glaze as a base glaze, and cover the silver-copper oxide composite glaze obtained above as a surface glaze. It is sintered and melted on the surface of ceramic products at 1200°C to form a dense glaze of silver-copper ...

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 and a preparation method and application thereof. Background technique [0002] Antibacterial ceramic products are mainly made by adding inorganic antibacterial agents to ceramic glazes, which are sintered at high temperatures to form an antibacterial glaze surface, which has 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 silver compound + , Enter the inside of the bacteria, causing the bacteria to die. At the same time, the catalytic action of silver ions decomposes oxygen into active oxygen O, killing bacteria. [0004] 2. Nano titanium dioxide TiO 2 (Photocatalyst). The antibacterial mechanism ...
