Abstract

The invention relates to silver-based eta-Al2O3 mesoporous fiber antibacterial powder and antibacterial ceramic. The antibacterial powder is prepared through shake adsorption of eta-Al2O3 mesoporous fiber, an AgNO3 solution and a silver-based coordination agent NH3.H2O, wherein the particle size of the antibacterial powder is 200nm, the pore diameter is 2-15nm, the average pore diameter is 6.6nm, the length is 5-12 microns, and the minimal inhibitory concentration is 120 micrograms / mL. According to the antibacterial powder and antibacterial ceramic provided by the invention, the eta-Al2O3 (PEG) mesoporous fiber is adopted as an antibacterial agent carrier, the good adsorption performance of the mesoporous fiber is effectively utilized, and the antibacterial powder has an obvious antibacterial effect; moreover, since Al2O3 is the main chemical component of ceramic glaze, when the mesoporous fiber is used as the carrier, the properties of the glaze are not changed, and the sintering temperature of the glaze can be reduced, thereby obviously improving the performance of a glaze layer.

Description

technical field [0001] The invention relates to the technical field of inorganic antibacterial materials, in particular to a silver-based η-Al 2 o 3 Mesoporous fiber antibacterial powder and antibacterial ceramics. Background technique [0002] As a class of inorganic antibacterial materials—antibacterial ceramics, it refers to building sanitary antibacterial ceramics. With the continuous improvement of people's living standards, the rise of home decoration and the wide application of push-pull alloy doors and windows, the sealing performance of doors and windows has been improved, but the opening degree has been reduced, so the ventilation performance has also declined. Coupled with the increasing popularity of air conditioners and heaters in families, people are creating a comfortable living environment that is warm in winter and cool in summer for themselves, and it also creates favorable conditions for the reproduction and growth of microorganisms and bacteria. On the...
