▎ 摘　　要

NOVELTY - Preparation of antibacterial master batch comprises dissolving copper acetate in propylene glycol solution to obtain 0.4-0.8 mol/L copper acetate glycol solution, cooling, centrifuging, filtering, taking filter residue, cleaning, and vacuum drying; dissolving in stearic acid, adding glucose while stirring, dropping silver acetate solution, continuously stirring for 3-5 hours, adding cuprous oxide powder, stirring for 1-2 hours, centrifuging, separating, cleaning obtained precipitate, adding graphene and deionized water, mixing, and spray drying; and stirring graphene composite antibacterial agent and high-carbon alkane, extruding at 130-230 degrees C, cooling extruded resin wire by room temperature purified water, granulating, fine vibration sieving, removing irregular granules, ventilating, cooling, and drying. USE - The method is used for preparing antibacterial master batch. ADVANTAGE - The master batch reduces the use amount of reducing agent, avoids generation of toxic gas nitrogen dioxide, and has good antibacterial effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene composite antibacterial masterbatch.
