Abstract

The invention discloses self-cleaning and antibacterial ceramic glaze. The ceramic glaze is prepared from components in parts by weight as follows: 20-90 parts of water, 30-65 parts of SiO2, 16-28 parts of Al2O3, 12-33 parts of CaCO3, 1-4 parts of B2O3, 1-9 parts of Na2SiO3, 1-6 parts of ZnO, 1-4 parts of CuO, 1-4 parts of MnO, 1-3 parts of MgH2, 0.04-5 parts of germanium hydroxides, 0.08-8 parts of gallium hydroxides, 0.5-3 parts of nano-indium tin oxides and 1-10 parts of an auxiliary. During component regulation, an unexpected discovery indicates that nano-indium tin oxides and nano-MgH2 have better antibacterial activity for common bacteria, the synergistic function of nano-indium tin oxides and nano-MgH2 is more excellent, nano-indium tin oxides and nano-MgH2 can be added to an inorganic material for preparation of an antibacterial material and the like, and the self-cleaning and antibacterial ceramic glaze has wide application prospect.

Description

technical field [0001] The invention relates to a ceramic, in particular to a self-cleaning and antibacterial ceramic glaze and a preparation method thereof. It belongs to the technical field of ceramics. Background technique [0002] Traditional ceramics are mainly white, and the glaze only uses zirconium silicate to play a white role, and has no other functions, and the traditional ceramic glaze is uneven under a magnifying glass, making it easy for dirt and bacteria to hide and multiply; later, in traditional ceramics After the finished product is fired, heat treatment of the coating film is added in the later stage. Without high-temperature firing, the coating film has poor stability and is easy to peel off, and finally loses the antifouling and antibacterial effect. In response to the above problems, various inorganic antibacterial materials with excellent antibacterial properties have been developed at home and abroad, and are widely used in various fields such as fib...
