Description

Ceramic material with excellent antibacterial property and preparation method thereof
Technical Field
The invention belongs to the technical field of ceramic materials, and particularly relates to a ceramic material with excellent antibacterial property and a preparation method thereof.
Background
The ceramic material has the best rigidity and the highest hardness in engineering materials, and the hardness of the ceramic material is mostly more than 1500 HV. The traditional ceramics mainly adopt natural rock, mineral, clay and other materials as raw materials, while the novel ceramics adopt artificially synthesized high-purity inorganic compounds as raw materials, and the inorganic materials with fine crystalline structures are prepared by molding, sintering and other treatments under strictly controlled conditions. The novel ceramic material has unique superiority in performance. In the aspects of thermal and mechanical properties, the material has the advantages of high temperature resistance, heat insulation, high hardness, abrasion resistance and the like; electrical properties such as insulation, piezoelectricity, semiconductivity, and magnetism; has the functions of catalysis, corrosion resistance, adsorption and the like in the chemical aspect. Ceramic materials are widely used in daily life due to superior properties such as corrosion resistance, but in seasons where microbes such as bacteria grow in summer, even if sanitation is maintained, the invasion of bacteria is difficult to avoid, and thus, antibacterial ceramics have appeared.
There are two main types of antibacterial ceramics: one is silver series slow-release antibacterial ceramic. The antibacterial agent is a combination of metal ions such as silver and copper with a certain carrier, namely a silver-based antibacterial agent. There are two views of its antibacterial mechanism: a silver ion slow-release sterilization mechanism and a silver ion catalysis hypothesis. However, current experimental findings tend to support the former, a common view being that the sustained-release antibacterial mechanism plays a decisive role. This also has the result that the silver-based antimicrobial agent kills bacteria but does not decompose and decontaminate bacterial debris. However, bacterial debris and its endotoxins are still extremely potent pathogenic agents. The other is nano titanium photo-catalyst type antibacterial ceramic. The antibacterial agent is a nano photocatalytic semiconductor material, such as ZnO and the like, namely a titanium dioxide photocatalyst antibacterial agent, and the antibacterial mechanism is nano photocatalytic antibacterial.
In the prior art, a ceramic material which can simultaneously have the advantages of silver-based antibiosis and nano titanium-based photocatalyst-type antibiosis is lacked.
