▎ 摘　　要

NOVELTY - A low-temperature-resistant and impact-resistant polyethylene terephthalate (PET) modified material is obtained by melting and extruding 100 pts. wt. polyethylene terephthalate and 10-20 pts. wt. modified reinforcing agent. The modified reinforcing agent is obtained by modifying the surface of graphene oxide with organosilicon. USE - Low-temperature-resistant and impact-resistant polyethylene terephthalate modified material used in food packaging, film processing, printing material and industrial component. ADVANTAGE - The PET modified material has excellent impact resistance, can maintain excellent impact resistance at low temperature, can withstand a low temperature of below -120°C, and can be stored for a long time without frost crack at -90°C. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of PET modified material, which involves mixing raw materials, melting, extruding and cooling.
