The high density polypropylene composite material consists of ethylene homopolymer 8-40 wt%, barium sulfate 40-80 wt%, talcum powder 0-20 wt%, calcium carbonate 0-20 wt%, PP-g-MAH 4-6 wt%, POE-g-MAH 0-3 wt%, molecular weight regulator 0.5-2 wt%, oleamide 0.5-1.5 wt%, erucyl amide 0.5-2 wt%, PP wax 0.5-2 wt%, coupling agent 1-1.5 wt%, and pigment 0-5 wt%. The high density polypropylene composite material has great specific weight, high strength, high toughness, excellent wear resistance, good handing and other advantages.

Description

technical field [0001] The invention relates to the technical field of composite materials, and more specifically relates to a special composite material for manufacturing chips used in the entertainment industry. Background technique [0002] The publication number is CN1587314A invention patent application discloses a kind of chip special plastics is to adopt raw materials such as PET to produce. The injection molding temperature of PET is as high as 270°C-280°C, which is difficult to process, insufficient toughness, brittle, easy to scratch the surface, and poor wear resistance. There are also white spots on the surface of the injection molded product, which causes the chip to have an unattractive appearance. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects in the prior art and provide a high-density polypropylene (PP) composite material for manufacturing chips used in the entertainment industry. The hig...
