Anti-static PVC composite material and preparation method thereof

The invention relates to the field of PVC materials, in particular to an anti-static PVC composite material and a preparation method thereof. The preparation method comprises the following steps: dissolving activated graphene in an ethanol solution, slowly pouring a dispersion liquid of hollow glass microspheres into the ethanol solution under the conditions of heating and magnetic stirring, carrying out a water bath reaction for a period of time, centrifuging, carrying out suction filtration, washing, and drying to obtain graphene powder coated with the hollow glass microspheres, wherein theanti-static PVC composite material comprises the following components in parts by weight: 64-90 parts of PVC resin, 5-7 parts of a plasticizer, 1-4 parts of an organic tin heat stabilizer, 2-20 partsof hollow glass microsphere modified graphene powder and 2-5 parts of a processing aid, and after plastifing by a double-roller plastifying machine, then performing hot press molding by a full-automatic tablet press to obtain
