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 ℃ to obtain a mixed solution; adding a hydrogen peroxide solution into the mixed solution, and removing potassium permanganate after reaction to obtain a reaction solution; filtering the reaction solution to obtain a solid A, and washing and drying the solid A to obtain oxidized fullerene; mixing oxidized fullerene, water, hexadecyl dimethyl tertiary amine, ethanol and sodium hydroxide, stirring for reaction for 10-14 h, filtering to obtain a solid B, washing and drying the solid B to obtain modified fullerene; mixing the modified fullerene, sodium octadecylbenzenesulfonate, potassium borohydride, zinc nitrate, N-dimethylformamide and water, reacting for 12-16 h, filtering to obtain solid C, washing the solid C, drying, grinding and sieving to obtain the antibacterial agent. The antibacterial agent prepared by the invention can obviously improve the antibacterial effect. |
