▎ 摘　　要

NOVELTY - Nano-antistatic glass fiber reinforced polyamide composite material comprises 50-75 wt.% polyamide resin, 10-40 wt.% glass fiber, 3-5 wt.% toughening agent and 5-10 wt.% nano antistatic agent as main raw materials, where the nano antistatic agent is graphene oxide and carbon nanotubes coated with ethylene acrylic acid copolymer on the surface. USE - The nano-antistatic glass fiber reinforced polyamide composite material is useful for replacing copper and non-ferrous metal in manufacturing machinery, chemical engineering and electrical parts e.g. diesel engine fuel pump gear, water pump, high pressure sealing ring and oil delivery pipe. ADVANTAGE - The method uses ethylene acrylic acid copolymer to coat graphene oxide and carbon nanotubes, and improves dispersion and compatibility of graphene oxide and carbon nanotubes in resin composites. The resin composite material has smaller surface resistance and better electrical conductivity, good antistatic properties, and solves problem of difficulty in blanking caused by the excessive addition of conductive additives. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of nano antistatic glass fiber reinforced polyamide composite material, comprising uniformly stirring the polyamide resin, lubricant, antioxidant, toughening agent and nano antistatic agent, adding to the doubles-screw extruder, adding glass fiber, melting and extruding at 180-265℃, and obtaining nano antistatic glass fiber reinforced polyamide composite material.
