一种耐划伤、高抗冲聚丙烯树脂材料及制备方法
摘要：
本发明公开了一种耐划伤、高抗冲聚丙烯树脂材料，其熔体流动速率为26~30g/10min，键合乙烯含量为9%～12%，简支梁缺口冲击强度≥10kJ/m2，挠曲模量≥1100MPa，热变形温度≥80℃，其以聚丙烯树脂、耐划伤剂、抗氧剂和吸酸剂为主要原料制备而成，其中，以聚乙烯的量为基准，所述原料间的质量比为：聚丙烯树脂﹕耐划伤剂=100﹕0.065~0.28，聚丙烯树脂﹕抗氧剂=100﹕0.1~0.25，聚丙烯树脂﹕吸酸剂=100﹕0.05~0.1。本发明还公开了该聚丙烯树脂材料的制备方法。该聚丙烯树脂材料耐划伤和高抗冲，仅添加少量的添加剂就可直接注射制备护板和立柱等汽车内饰部件。
摘要（英）：

The invention discloses a scratch-resistant high-impact polypropylene resin material. The melt flow rate is 26-30 g/10 min, the content of bonding ethylene is 9-12%, the notch impact strength of a simply supported beam is larger than or equal to 10 kJ/m<2>, the flexural modulus is larger than or equal to 1100 MPa, and the heat distortion temperature is higher than or equal to 80 DEG C. The scratch-resistant high-impact polypropylene resin material is prepared from polypropylene resin, a scratch-resistant agent, an antioxidant and acid acceptor as main raw materials, and the mass ratio of polypropylene resin to scratch-resistant agent to antioxidant to acid acceptor is 100:0.065-0.28:0.1-0.25:0.05-0.1 with the amount of polyethylene as the baseline. The invention further discloses a preparing method of the polypropylene resin material. The polypropylene resin material is resistant to scratches and high in impact and can be directly injected to manufacture automobile interior components such as a protective plate and a stand column just by adding a small quantity of additives.
