Method for preparing three-component coprecipitation molybdate antimicrobial by using microwave heating

Abstract

The invention relates to a method for preparing Ag2MoO4-ZnMoO4-CuMoO4 by microwave heating. A test proves that the chemical reaction of the antimicrobial can be promoted to finish under microwave heating condition, thereby greatly shortening the preparation time of the antimicrobial. And when three components of coprecipitation molybdate antimicrobial powder body solution are prepared, a coprecipitation way is adopted, so that the grain diameter of the antimicrobial is evener, and the antimicrobial effect is improved. Through analyzing and comparing the XRD of a baking sample which is not baked at 1260 DEG C, the three components of molybdate antimicrobial has fine stability at high temperature. And the compound of parts of CuMoO4 and ZnMoO4 substitutes the compound of Ag2MoO4, so that the cost of the antimicrobial is lowered. The prepared Ag2MoO4-ZnMoO4-CuMoO4 antimicrobial is added into sanitary porcelain according to the proportion that the dosage of the antimicrobial is 1 to 2wt percent of the gross weight of dried glaze, and is baked at about 1260 DEG C to obtain an antimicrobial ceramic sample. Through an antimicrobial performance test, the bacteriostatic ratios of antimicrobial ceramic to colon bacillus and staphylococcus aureus are both at over 90 percent which accords with the standard of the antimicrobial ceramic in the building material industry.

Description

Technical field: [0001] The invention relates to a preparation technology of an inorganic antibacterial agent and a method for introducing it into sanitary ceramics. Background technique: [0002] With the general improvement of human material living standards and civilization, the awareness of self-protection is increasing day by day. It is increasingly desirable to create a good ecological environment that reduces germs as much as possible. Antibacterial building sanitary ceramics are health and safety products used in buildings, homes and public places. Antibacterial building sanitary ceramics are widely used in toilets, hospital wards, swimming pools and other places where human activities are frequent and bacteria are easy to grow and spread. The requirements for reducing excrement pollution and cross-infection in public places are also becoming stronger and stronger. This is the development of antibacterial sanitary ceramics. offers broad prospects. [0003] At pres...
