NOVELTY - Improving compressive strength of plastic composite heat conducting material involves preparing raw material by using 42-48 pts. wt. polypropylene, 18-24 pts. wt. hydrogenated diene copolymer, 2-6 pts. wt. zinc sulfide, 8-12 pts. wt. graphene, 6-10 pts. wt. nickel oxide nano fiber, 2-4 pts. wt. carboxyl-terminated polyester resin, 1-3 pts. wt. plate-like titanates with an average particle size of 20-40 mu m and 0.2-0.6 pts. wt. antioxidant. USE - Method for improving compressive strength of plastic composite heat conducting material. ADVANTAGE - The method enables to improve compressive strength of plastic composite heat conducting material in a simple, eco-friendly and cost-effective manner, and has enhanced thermal stability. DETAILED DESCRIPTION - Improving compressive strength of plastic composite heat conducting material involves preparing raw material by using 42-48 pts. wt. polypropylene, 18-24 pts. wt. hydrogenated diene copolymer, 2-6 pts. wt. zinc sulfide, 8-12 pts. wt. graphene, 6-10 pts. wt. nickel oxide nano fiber, 2-4 pts. wt. carboxyl-terminated polyester resin, 1-3 pts. wt. plate-like titanates with an average particle size of 20-40 mu m and 0.2-0.6 pts. wt. antioxidant. The hydrogenated diene-based copolymer, zinc sulfide, nickel oxide nanofibers, and plate-like titanates having an average particle size of 20-40 mu m are mixed in a weight ratio and then ball milled in a nitrogen atmosphere for 4-6 hours. Polypropylene, graphene and carboxyl-terminated polyester resin are mixed in a mixer, and setting the temperature of the front, middle and back of the mixer to be the same, and is 180-220 degrees C. The obtained mixture is stirred with the rotation speed of 40-80r/min for 20-40 minutes for further use. The mixing material, composite particle and antioxidant are added in a screw-type extruder at temperature 240-260 degrees C. The obtained mixture is plasticized, extruded, and then cooled.
