The invention discloses a stain-resistant antistatic PVC composite film. According to the stain-resistant antistatic PVC composite film, an antistatic PVC composite film is used as a substrate, and astain-resistant self-cleaning agent is printed on the surface of the substrate in a silk-screen mode; the antistatic PVC composite film comprises the following components in percentage by weight: 45-65% of polyvinyl chloride, 10-14% of polytetrafluoroethylene, 12-18% of an acrylic monomer, 6-10% of hydroxylated graphene, 4-6% of aminated graphene, 0.1-0.5% of a catalyst, 1.8-4% of hyperbranched polystyrene, 1-2% of polypyrrole and 0.1-0.5% of a dispersing agent. The stain-resistant self-cleaning agent is prepared from the following components in percentage by weight: 30 to 55 percent of nano TiO2 sol, 5 to 10 percent of nano silver powder, 10 to 15 percent of a lotus leaf hydrophobic agent, 10 to 15 percent of perfluorooctyltriethoxysilane and 20 to 30 percent of perfluoroalkyl ethyl acrylate. According to the invention, graphene is introduced into an acrylic polymer molecular chain under the chemical cross-linking action of graphene with a special functional group structure and acrylic resin, and the modified graphene conductive particles are stably compatible with PVC resin by utilizing the principle of similarity and compatibility among media, so that the PVC composite film haspermanent antistatic capacity.
