▎ 摘　　要

NOVELTY - Antistatic graphene-coated aluminum microsphere modified polypropylene composite material is composed of 55-75 pts. wt. polypropylene, 10-20 pts. wt. talc, 5-20 pts. wt. conductive powder, 2-8 pts. wt. coupling agent, 0.5-1.5 pts. wt. lubricant and 0.3-1.0 pts. wt. antioxidant. The conductive powder is a conductive mixture of graphene-coated aluminum microspheres prepared by a typical molecular-level mixing method. USE - Antistatic graphene-coated aluminum microsphere modified polypropylene composite material. ADVANTAGE - The mixture of graphene-coated aluminum microspheres is used as the conductive powder, and a small amount of conductive powder is added to have higher conductivity. A small amount of talc powder is selected as the blend, which can improve the tensile strength, impact strength and thermal deformation temperature of the composite material, and finally prepare a new PP composite material with excellent mechanical properties and antistatic effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an antistatic graphene-coated aluminum microsphere modified PP composite material, which involves: (A) weighing PP, talcum powder, conductive powder, coupling agent, lubricant and antioxidant according to the ratio and mixing them uniformly, then putting them in a high-speed mixer and stir for 30-60 minutes; (B) observing the state of the material, and observing that the physical form of the material no longer changes during the mixing process; (C) adding the mixture into a twin-screw extruder for extrusion and granulation; and (D) drying the produced particles in a blast dryer to prepare the antistatic PP composite material.
