▎ 摘  要

NOVELTY - A high-anti-cracking degradable modified plastic based on modified graphene comprises 60-75 pts. wt. polylactic acid (PLA), 25-40 pts. wt. polybutylene succinate (PBS), 6-12 pts. wt. modified graphene, 10-30 pts. wt. functional anti-cracking components, 1-5 pts. wt. chain extender, 0.5-2 pts. wt. antioxidant, 0.1-1 pt. wt. anti-UV agent, and 0.2-0.8 pt. wt. anti-hydrolysis agent. USE - High-anti-cracking degradable modified plastic. ADVANTAGE - The modified plastic has excellent strength, toughness, crack resistance and heat-resistant stability, does not burden the environment, and can be completely degraded by composting within a period of time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the degradable modified plastic based on modified graphene, which involves adding PLA and functional anti-cracking components to main feeding port of the twin-screw extruder, adding remaining raw material components to a side feeding port of the twin-screw extruder, melt-blending at 170-190degrees Celsius, extruding, and granulating.
