Problems solved by technology

However, silver-loaded inorganic antibacterial agents are easy to change color, which limits its wide application in composite materials; copper-loaded montmorillonite has certain inhibitory effects on Staphylococcus aureus and Escherichia coli, and because of its own color, it also limits its application in composite materials

Embodiment 1

[0017] Prepare 22g of montmorillonite and deionized water into a 10% suspension, add 1g of zinc chloride, stir at 60°C for 3 hours, add 2g of octadecyltrimethylammonium chloride, heat up and stir, and stir at 70°C After stirring continuously for 3 hours, filter with suction, wash repeatedly with distilled water, then vacuum-dry at 65°C for 48 h, grind, and pass through a 300-mesh sieve to obtain sample 1.

[0018] The glass culture dish and prepared nutrient agar were cultured in a high-temperature sterilization pot, and sterilized at 0.15 MPa for 20 minutes. Nutrient agar cultures were then incubated in a 52°C water bath. Take 4, 2, 1, 0.5, 0.25, 0.125 and 0.0625mg of sample 1, add appropriate amount of water to dissolve into a slurry and place it in a 10mL centrifuge tube, take about 0.2mL of the prepared bacterial solution in the centrifuge tube, and then add an appropriate amount of Pour the nutrient agar medium into the centrifuge tube to the full scale, shake well and p...

Abstract

The invention discloses a zinc-carrying nano organic montmorillonite antimicrobial agent which is prepared from the following components in percentage by weight: 8-15% of zinc chloride, 13-16% of organized intercalation treating agent and 69-79% of montmorillonite. The preparation method comprises the following steps: preparing 69-79% of montmorillonite and deionized water into a 10% suspension, adding 8-15 wt% of zinc chloride, stirring at 60-70 DEG C for 3-4 hours, adding 13-16% of organized intercalation treating agent, heating while stirring, continuing stirring at 70-80 DEG C for 4-5 hours, carrying out vacuum filtration, repeatedly washing with distilled water, carrying out vacuum drying at 65 DEG C for 48 hours, grinding, and passing through a 300-mesh screen to obtain the zinc-carrying nano organic montmorillonite antimicrobial agent. The antimicrobial agent has the advantages of high efficiency and broad antibacterial spectrum.

Description

technical field [0001] The invention relates to an antibacterial agent and a preparation method thereof, in particular to a zinc-loaded nanometer organic montmorillonite antibacterial agent and a preparation method thereof. Background technique [0002] With the development of economy and society, people's requirements for living environment and their own health are constantly improving. Harmful bacteria are widely distributed in nature and there are many kinds, which threaten human health. Especially in recent years, global microbial disasters caused by microorganisms and their variants have occurred frequently. Materials with antibacterial and bactericidal functions have attracted more and more attention. The development of antibacterial agents with good antibacterial properties is the key to the development of antibacterial materials. [0003] The antimicrobial agents currently used are mainly divided into two categories: organic and inorganic. Organic antibacterial age...
