▎ 摘　　要

NOVELTY - Antistatic controllable biodegradable foaming material comprises a degradable copolyester composition and a foaming auxiliary agent. The composition comprises 100 pts. wt. degradably copolyesters, and 0.05-5 pts. wt. antistatic agent, where the anti-static agent is edge-modified graphene. The edge modified graphene has an average sheet diameter of 2-30 microns, preferably 5-15 microns. The average aspect ratio is 600-10000:1, preferably 1500-3800:1. USE - The foaming material is used for foaming beads and foaming bead forming body for preparing electronic packaging buffer material used in electric appliance and electronic product buffer package. ADVANTAGE - The antistatic controllable biodegradable foaming material has good hydrophobic performance, effectively solves the problem that the polyester in the water solvent kettle pressure foaming problem, the preparation method of the degradable copolyester composition is simple and effective and easy to operate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: preparation method of antistatic controllable biodegradable foaming material; antistatic controllable biodegradable foaming bead; and antistatic controllable biodegradable foaming bead forming body.
