▎ 摘 要
NOVELTY - Anti-aging BOPP film comprises 85-95 pts. wt. polypropylene, and 0.01-0.1 pts. wt. oxygen-resistant modified graphene. The anti-oxygen modified graphene is obtained by grafting reaction of graphene and antioxidant. USE - Anti-aging BOPP film used in film capacitor (claimed). ADVANTAGE - The anti-aging BOPP film has good anti-aging performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing anti-aging BOPP film, which involves weighing the raw material according to parts by weight, mixing and melting each raw material at 180-250degrees Celsius by a screw extruder, extruding the molten body through the casting die head to obtain the BOPP film, heating the film to 110-140degrees Celsius, orderly performing transverse stretching and longitudinal stretching, after stretching, cooling the film to 20-30degrees Celsius in 10 s, obtaining anti-aging BOPP film.
