[0022] A silver-based η-Al 2 o 3 The preparation method of mesoporous fiber antibacterial powder comprises the following steps:

[0023] 1) Dissolve PEG600 in deionized water at a weight ratio of 1:5 to obtain a transparent solution A, and then take Al(NO 3 ) 3 9H 2 O was added to solution A, and solution B was obtained after complete dissolution;

[0024] 2) Take CO(NH at a weight ratio of 5:17 2 ) 2 Add solution B to obtain solution C after completely dissolving, and transfer solution C to the reaction kettle to obtain reaction product D through hydrothermal reaction; the conditions of hydrothermal reaction are: the filling degree of the reaction kettle is 70-80%, and the reaction The temperature is 100-140°C.

[0025] 3) Take out the reaction product D in the reaction kettle and cool it down to room temperature naturally, then obtain the product E by suction filtration, wash the product E with deionized water and absolute ethanol respectively, dry it, and grind i...

Abstract

The present invention relates to a preparation method of silver-based η-Al2O3 mesoporous fiber antibacterial powder, comprising: 1) dissolving PEG600 in deionized water to obtain solution A, adding Al(NO3)3·9H2O to obtain solution B; 2) taking CO(NH2)2 was added to solution B to obtain solution C, and solution C was hydrothermally reacted to obtain product D; 3) product D was taken out, cooled and filtered to obtain product E, product E was washed, dried, and ground to obtain a precursor 4) Soak the mesoporous fiber in AgNO3 solution, add NH3·H2O, oscillate and adsorb to obtain silver-based η-Al2O3 mesoporous fiber antibacterial powder. The present invention adopts η-Al2O3 (PEG) mesoporous fiber as the carrier of antibacterial agent, effectively utilizes the good adsorption performance of mesoporous fiber, and the prepared antibacterial powder has obvious antibacterial effect, and since Al2O3 is the main chemical substance of ceramic glaze Components, using the mesoporous fiber as a carrier not only does not change the properties of the glaze, but also reduces the sintering temperature of the glaze and significantly improves the performance of the glaze layer.

Description

technical field [0001] The invention relates to the technical field of mesoporous fiber preparation and inorganic antibacterial powder, in particular to a silver-based η-Al 2 o 3 The preparation method of mesoporous fiber antibacterial powder. 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 microor...
