▎ 摘  要

NOVELTY - Producing polyolefin film, involves (S1) preparing graphene modified polyolefin by (S11) adding maleic anhydride, graphene and polyolefin particles to a ball mill to obtain mixture (A), and (S12) melting and blending an initiator, mixture (A), stabilizer and polypropylene resin in extruder to obtain graphene-modified polyolefin, (S2) carrying out high-speed densification and melt extrusion granulation on graphene modified polyolefin to prepare masterbatch, (S3) melting and extruding masterbatch, quenching, measuring thickness, corona processing, rolling, slitting and packaging, and stretching. USE - Producing polyolefin film used in automobile, electric appliance, and packaging applications. ADVANTAGE - The polyolefin film has excellent oxygen resistance, high crosslinking degree, excellent stability and high strength.
