NOVELTY - Heat conducting filler master batch comprises 30-40 pts. wt. high pressure polyethylene, 45-55 pts. wt. aluminum oxide, 10-20 pts. wt. graphene, 0.5-2 pts. wt. coupling agent, 0.2-0.5 pts. wt. dispersant, and 0.2-0.5 pts. wt. antioxidant. USE - Heat conducting filler master batch used in polypropylene composite material for extruding and absorbing plastic and preparation of electronic component (claimed). ADVANTAGE - The master batch can reduce the agglomeration phenomenon of the heat conducting filler in the processing process, improve the dispersion of the heat conducting filler in the resin. The polypropylene composite material has good heat conducting performance and mechanical property, and the satisfy client extruding plastic processing requirement. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparation method of the heat-conducting filler master batch comprising providing raw material, mixing, extruding and granulating to obtain the product; polypropylene composite material for extruding and absorbing plastic, comprising 30-45 pts. wt. polypropylene, 10-15 pts. wt. toughener, 2-5 pts. wt. compatibilizer, 0.2-0.5 pts. wt. antioxidant, and 40-50 pts. wt. heat conducting filler master batch; and preparation method of polypropylene composite material for extruding and absorbing plastic comprising providing raw materials, mixing, extruding and granulating by extruder.
