High-rigidity and high-heat-resistance carbon fiber reinforced PP material and preparation method thereof

The invention discloses a high-rigidity and high-heat-resistance carbon fiber reinforced PP material and a preparation method thereof. The high-rigidity and high-heat-resistance carbon fiber reinforced PP material comprises a first mixture and a second mixture, the first mixture is prepared from COC resin, an ethylene copolymer, PP resin and an antioxidant; the second mixture is made of carbon fibers; and the high-rigidity and high-heat-resistance carbon fiber reinforced PP material is prepared by extruding and granulating the first mixture and the second mixture. The preparation method comprises primary granulation and secondary granulation. The preparation method of two-step granulation and ultrasonic vibration granulation provided by the invention solves the problem of immiscibility ofa PP/COC system, and the carbon fiber reinforced PP material prepared by the invention has excellent rigidity and heat resistance. 本发明公开了一种高刚性高耐热的碳纤维增强PP材料及其制备方法，其包括：第一混合物，所述第一混合物由COC树脂、乙烯共聚物、PP树脂、抗氧剂制得；第二混合物，所述第二混合物由碳纤维制得；以及
