NOVELTY - Continuously rolling and molding polyvinyl chloride/graphene composite film comprises (1) placing polyvinyl chloride resin, thickener, stabilizer, filler, improver and auxiliary material into mixer, pouring into mixer, adding graphene powder, (2) passing mixture into internal mixer through cold mixer under pressure of the floating weight, plasticizing by two counter-rotating rotors so that the mixture will be plasticized in the shortest time, discharging solids, (3) placing block material discharged from the internal mixer into the open mixer and further plasticizing into flakes to make the components more uniform, (4) placing material discharged from the mill into mixer to cool down, filtering and removing by machine head Impurities, (5) conveying sheet material to the four-roller calender by belt for calendering and forming, (6) peeling off calendered composite film and performing embossing treatment, and (7) sampling and testing according to product quality standards. USE - The method is useful for continuously rolling and molding polyvinyl chloride/graphene composite film, which is useful for producing high molecular material film and sheet. ADVANTAGE - The composite film has higher strength and can make thickness more uniform, can allow larger traction degree and can be processed at lower temperature after molding. DESCRIPTION OF DRAWING(S) - The drawing shows the structure schematic diagram of the calender. 1Fixing plate 2First roller 3Second roller 4Third roller 5Fourth roller 8Protective cover 10Driving motor
