preparation example Construction

[0033] see figure 1 , the preparation method of the antibacterial agent that the present invention proposes, comprises the following steps:

[0034] S10. Add fullerene, potassium nitrate, concentrated sulfuric acid, and potassium permanganate into water, and stir at 30-40° C. to obtain a mixed solution.

[0035] In this step, concentrated sulfuric acid and potassium permanganate are used as oxidants to oxidize and modify the surface of fullerene, potassium nitrate combines with hydrogen ions in the solution to form nitric acid to enhance the oxidation effect, and water is used as a dispersion medium to provide a solution for the reaction The environment is conducive to the carrying out of the reaction. The water is preferably deionized water, which can effectively prevent the impact of impurity ions in the water on the reaction.

[0036] The proportioning of fullerene, potassium nitrate, concentrated sulfuric acid, potassium permanganate is not limited in the present inventio...

Abstract

The invention discloses a preparation method of an antibacterial agent, a thermoplastic resin composite material and a preparation method thereof, and relates to the technical field of high polymer materials. The preparation method of the antibacterial agent comprises the following steps: adding fullerene, potassium nitrate, concentrated sulfuric acid and potassium permanganate into water, and stirring at 30-40 DEG C to obtain a mixed solution; adding a hydrogen peroxide solution into the mixed solution, reacting, and removing potassium permanganate to obtain a reaction solution; filtering the reaction liquid to obtain a solid A, and washing and drying the solid A to obtain fullerene oxide; mixing fullerene oxide, water, hexadecyl dimethyl tertiary amine, ethanol and sodium hydroxide, stirring and reacting for 10-14 hours, filtering to obtain a solid B, and washing and drying the solid B to obtain modified fullerene; and mixing the modified fullerene, sodium octadecyl benzene sulfonate, potassium borohydride, zinc nitrate, N, N-dimethylformamide and water, reacting for 12-16 hours, filtering to obtain a solid C, and washing, drying, grinding and sieving the solid C to obtain the antibacterial agent. The antibacterial agent prepared by the method can obviously improve the antibacterial effect.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a preparation method of an antibacterial agent, a thermoplastic resin composite material and a preparation method thereof. Background technique [0002] Antibacterial agents refer to substances that can effectively control the growth of microorganisms or directly kill microorganisms. Antibacterial agents are widely used in plastics, with an annual growth rate of about 3.5% to 4%. However, the existing antibacterial agents have poor antibacterial effects. Contents of the invention [0003] The main purpose of the present invention is to propose a preparation method of an antibacterial agent, a thermoplastic resin composite material and a preparation method thereof, aiming at preparing an antibacterial agent, which can significantly improve the antibacterial effect when used in a thermoplastic resin composite material. [0004] In order to achieve the above object, the...
