中文摘要:
      进行了橡胶再生剂与相容剂并用在废轮胎胶粉(GRT)增韧废PP复合材料中的应用研究。结果表明，采用橡胶再生剂De-link/相容剂CA并用改性GRT/废PP复合材料的冲击强度可达22.6 kJ·m-2，比简单GRT/废PP共混体系提高了2.4倍，比废PP体系提高了2倍；拉伸强度则比简单GRT/废PP共混体系提高了30%，为废PP体系的87%；再生剂通过改变胶粉的交联度来提高复合材料的韧性，相容剂主要通过改善界面性能和提高相容性来提高复合材料的力学性能。
英文摘要:
      The application of the reclaiming agent and compatibilizer to GRT-toug hened waste PP was investigated.The results showed that the impact strength of the GRT-toughened waste PP was in-creased by 240% to 22.6 kJ·m-2 by the modification with the reclaiming agent De-link/compatibilizer CA and the tensile strength was increased by 30%；the crosslink density of GRT was changed by the reclaiming agent to increase the tougheness of the composite，and the properties of the interface were improved by the compat ibilizer to improve the mechanical properties of the composite.
