NOVELTY - Preparing modified polybutylene adipate terephthalate (PBAT) biodegradable plastic involves firstly placing PBAT particles in a blast oven at 60-80degrees Celsius, taking out PBAT particles after being fully dried for 6-8 hours. The plasticizer is added, and the mixture is fully stirred so that the plasticizer is uniformly adhered to the surface of the PBAT particles to obtain a first mixture. The first mixture is placed in a torque rheometer for melt blending, cooled and diced to obtain a first product. The first product is taken out and performing hot press molding by using a tablet press to obtain the modified PBAT plastic test sample strip. USE - Method for preparing modified polybutylene adipate terephthalate (PBAT) biodegradable plastic. ADVANTAGE - The method enables to improve the mechanical property and the elongation at break of the PBAT, which leads the PBAT to be more widely applied and greatly improves the antistatic property under the condition of little addition of graphene, and is easy to operate, green and eco-friendly and cost-effective aslo. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing antistatic plastic, which involves: (1) placing PBAT particles in a blast oven at 60-80degrees Celsius, taking out PBAT particles after being fully dried for 6-8 hours. The plasticizer is added, and the mixture is fully stirred so that the plasticizer is uniformly adhered to the surface of the PBAT particles to obtain a first mixture. (2) The first mixture is placed in a torque rheometer for melt blending, cooled and diced to obtain a first product. (3) The first product is added into an organic solvent A, added an ultrasonically-stripped graphene solution, and fully and uniformly stirred to obtain a second mixture, where feeding mass ratio of the graphene and first product is 1-5:100, respectively. (4) The second mixture is poured and molded.
