The invention discloses antistatic degradable plastic particles and their preparation method, belonging to the technical field of degradable plastics. The raw materials include (by weight): 50-60 parts of polylactic acid, 40-50 parts of antistatic masterbatch, 2-4 parts of graphene oxide, 0.5-4 parts of lubricant and 3-8 parts of plasticizer. The preparation steps are as follows: Mix dried polylactic acid, antistatic masterbatch, graphene oxide, lubricant and plasticizer uniformly in a high-speed mixer, then transfer the mixture to a twin-screw extruder for melt blending at 180-200℃, followed by extrusion and granulation. Using polylactic acid as the base material, the combined use of antistatic masterbatch and graphene oxide not only improves the mechanical properties of degradable plastic particles, but also increases the dissipation paths of free electrons, thereby significantly enhancing antistatic performance.
