NOVELTY - Antibacterial and antistatic film material comprises 100 pts. wt. thermoplastic polyurethane elastomer, 0.5-1 pts. wt. silver-loaded graphene, 0.3-1 pts. wt. aminated carbon nanotube, 0.1-0.5 pts. wt. hydrolysis resistant agent, 0.1-1 pts. wt. ultraviolet absorber, 0.5-15 pts. wt. plasticizer and 0.1-0.5 pts. wt. antioxidant, where the thermoplastic polyurethane elastomer is at least two of polyether polyurethane elastomer and polyester polyurethane elastomer, and has Shore hardness of 55-95 A and particle size of 3-6 mm. USE - Used as antibacterial and antistatic film material. ADVANTAGE - The film material has high mechanical intensity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing antibacterial and antistatic film material, comprising (1) preparing silver-loaded graphene and aminated carbon nanotubes, (2) mixing thermoplastic polyurethane, silver-loaded graphene and aminated carbon nanotubes thoroughly in a mixer, and subsequently adding hydrolysis resistant agent, antioxidant, ultraviolet absorber, and plasticizer to perform extrusion granulation through a twin-screw extruder, and vacuum drying to obtain the product, and (3) casting dried material through the feed port of the casting machine to the roll surface of the casting roll to form film, and the film moves through the cooling liquid with the casting roll, forming a film, and finally crimping the formed film, where the casting film production line speed is 150-200 cm/minute, the cast film thickness is 0.025-0.08 mm, and the cast film width is 2200 mm.
