NOVELTY - Preparation of graphene microchip antistatic polypropylene, involves adding graphene microchip, polypropylene and polypropylene-grafted maleic anhydride in a total amount of 1/2-2/3 in a xylene solution (analytical grade), heating, stirring, removing solution in the premix, drying, adding the resulting product with remaining polypropylene and remaining polypropylene-grafted maleic anhydride, and 1-3 pts. wt. processing aid in a high mixing machine, mixing evenly for 5-10 minutes, and melt-mixing he mixture with a torque rheometer for 10-30 minutes, and then discharging. USE - Preparation of graphene microchip antistatic polypropylene used in automobile interior components. ADVANTAGE - The method prepares graphene microchip antistatic polypropylene at low cost. The graphene microchip antistatic polypropylene has high efficiency, excellent dispersibility, and anti-static and anti-dust characteristics. DETAILED DESCRIPTION - Preparation of graphene microchip antistatic polypropylene, involves preparing raw materials which comprise 5-15 pts. wt. graphene microchip, 70-100 pts. wt. polypropylene, 5-15 pts. wt. polypropylene-grafted maleic anhydride and 1-3 pts. wt. processing aid where the polypropylene has melt index of 2-20 g/minute, and the grafting ratio of the polypropylene-grafted maleic anhydride is 0.6-0.8%, (ii) taking graphene microchip, polypropylene and polypropylene-grafted maleic anhydride in a total amount of 1/2-2/3, adding in a xylene solution (analytical grade), heating at 100-150 degrees C, and continually stirring, removing the solution in the premix after the raw materials are completely dissolved, and then drying at 80-100 degrees C, (ii) adding the resulting product with the remaining polypropylene and the remaining polypropylene-grafted maleic anhydride, and 1-3 pts. wt. processing aid in a high mixing machine, mixing evenly for 5-10 minutes, and melt-mixing he mixture with a torque rheometer for 10-30 minutes at a speed of 40-120 rpm and mixing temperature of 120-200 degrees C, and then discharging.
