The present invention discloses a preparation method of a graphene antibacterial stone-plastic masterbatch, comprising the following steps: S1, obtaining the following components in parts by weight: 60–70 parts of a matrix resin, 10–20 parts of graphene oxide powder, 1–5 parts of a dispersant, 1–9 parts of nano-fullerene particles, and 1–9 parts of nano-silver antibacterial powder; S2, sequentially adding the matrix resin, graphene oxide powder, dispersant, nano-fullerene particles and nano-silver antibacterial powder into a vessel of an ultrasonic nano-material disperser in proportion for ultrasonic dispersion; S3, taking out the raw materials after ultrasonic dispersion, adding them into a twin-screw extruder, cooling the extruded resin threads with room-temperature purified water, and cutting them into pellets by a pelletizer to obtain the graphene antibacterial stone-plastic masterbatch. By adding C60 nano-fullerene particles, the present invention not only ensures high overall stability of the graphene antibacterial stone-plastic masterbatch, but also enables the nano-fullerene particles to promote the photon-catalytic oxidation ability of graphene and enhance the antibacterial effect.
