Description

一种耐低温冲击聚丙烯组合物 技术领域
本发明涉及聚丙烯的改性，特别涉及到一种耐低温冲击聚丙烯组合物。
背景技术
聚丙烯是汽车用塑料中用量最大的品种，具有密度低、性能好、易加工等特点，已成为车用塑料中用量最大的品种。然而聚丙烯耐低温冲击性能差，当汽车在寒冷天气下聚丙烯塑料会产生形变，影响行驶安全和汽车外观。为了提高聚丙烯的低温韧性，常添加弹性体进行增韧。公开号为CN 103665570A采用氧化二异丙苯与聚烯烃弹性体交联得到XPOE作为增韧剂；CN103087429 B采用己烯和辛烯为支链的多支链聚乙烯为裂纹扩散的抑制剂，提升聚丙烯材料的耐低温冲击性能，然而上述专利公开的聚丙烯组合物存在耐冲击性能不足的缺陷，特别是在温度较低的条件下耐冲击性能改善不明显，远达不到汽车在低温恶劣条件下安全行驶的需求。因此，如何开发出一种耐低温冲击聚丙烯组合物成为当今社会亟待解决的问题。
