Embodiment 1

[0023] In this process, the magnesia clay is calcined at a temperature of 100-850°C for 10-120 minutes to obtain an active magnesia clay carrier material with strong adsorption properties; copper sulfate is selected as the fungicide, and it is formulated into 0.1-1.0mol / l solution; the active magnesia clay is formulated into a slurry at a solid-to-liquid ratio of 5 to 30%, and then a solution of copper sulfate with 3 to 10% of the active magnesia clay is added, and the reaction temperature is controlled to be 10 to 95°C and the reaction time is 1 ~8h, react under dynamic conditions, make copper ions fully interact with magnesia clay, magnesia clay will absorb copper ions into its pore layer structure, after washing to pH value = 6.5~7, after dehydration, place in 100℃ drying and grinding at high temperature to obtain copper-based magnesia clay antibacterial material.

Embodiment 2

[0025] In this process, the magnesia clay is calcined at 100-850°C for 10-120 minutes to obtain an active magnesia clay carrier material with strong adsorption properties; zinc sulfate is selected as the fungicide, and it is formulated into 0.1-1-0mol / 1 solution; the active magnesia clay is made into slurry at a solid-to-liquid ratio of 5-30%, and then a solution of 3-10% zinc sulfate of the active magnesia clay is added, and the reaction temperature is controlled to be 30-95°C and the reaction time is 1 to 8 hours, react under dynamic conditions, so that the zinc ions can fully interact with the magnesia clay, and the magnesia clay will absorb the zinc ions into its pore layer structure, and after washing, dehydration, drying, grinding and other processes, the zinc ions can be obtained. It is a magnesia clay antibacterial material.

Embodiment 3

[0027] The magnesia clay in this process is calcined at a temperature of 100-850°C for 10-120 minutes to obtain an active magnesia clay carrier material with strong adsorption properties; silver nitrate is selected as the fungicide and formulated into 0.1-1.0mol / l solution; the active magnesia clay is formulated into a slurry at a solid-to-liquid ratio of 5 to 30%, and then a solution of silver nitrate with 2 to 6% of the active magnesia clay is added, and the reaction temperature is controlled to be 30 to 95°C and the reaction time is 1 ~10h, react under dynamic conditions, so that the silver ions fully interact with the magnesia clay, and the magnesia clay absorbs the silver ions into its pore structure, and after washing, dehydration, drying, grinding and other processes, the silver system is obtained. Magnesia clay antibacterial material.

[0028] The antibacterial effect of magnesia clay antibacterial materials was tested by preparing antibacterial coatings. In this expe...

Abstract

The magnesia clay antibiotic material preparing process includes the following steps: heat activating magnesia clay through calcining at 100-850deg.c for 10-120 min to prepare the antibiotic carrier; preparing antiseptic solution in 0.1-1.0 mol/L concentration; compounding active magnesia clay slurry with solid content of 5-30wt%, adding antiseptic solution in 3-10 wt% of active magnesia clay and reaction at 10-95deg.c for 1-10 hr for complete reaction between the antiseptic ion and magnesia clay and adsorption of antiseptic ion to the porous magnesia clay structure; and washing, dewatering, stoving and grinding. The magnesia clay antibiotic material is used mainly for household appliance, chemical building material, telecomm product, food package, etc.

Description

technical field [0001] The invention relates to a preparation process of an antibacterial material, in particular to a preparation process of a magnesia clay antibacterial material. Background technique [0002] With the improvement of living standards, people's awareness and requirements for the living environment are constantly improving, especially the awareness of health is also constantly increasing. Because harmful bacteria are widely distributed in nature, and there are various types and large numbers, they seriously threaten human health. The diseases produced by bacterial transmission and infection have constituted a major social problem and have attracted widespread attention. As a result, there has been an "antibacterial craze" all over the world. Researchers are committed to the research and development of various antibacterial agents and antibacterial materials to prevent the spread of bacteria, reduce bacterial infections, and improve the quality of life.
