The invention discloses a preparation method of modified PBAT biodegradable plastic, which comprises the following steps: firstly placing PBAT particles in a blast oven, setting a temperature of 60-80 DEG C, fully drying them for 6-8 hours, then taking out, and then adding Plasticizer ATBC, fully stirred to make the plasticizer evenly adhere to the surface of PBAT to obtain the first mixture; the first mixture was placed in a torque rheometer for melt blending, and the first product was obtained after cooling and pelletizing; Step 2) The first product after dicing is taken out, and hot-pressed with a tablet press to obtain a modified PBAT plastic test strip. The invention also provides a preparation method of antistatic plastic. The preparation method of the antistatic plastic is to add modified PBAT to the graphene solution exfoliated with HBPE, stir and mix, and cast the antistatic plastic to form a film. The invention improves the mechanical properties and elongation at break of the PBAT, makes the PBAT more widely used, and greatly improves the antistatic performance of the PBAT under the condition of a small amount of graphene added. |
