摘　要：为了改善废轮胎胶粉(GRT)增韧废PP复合材料的力学性能，用橡胶再生剂De-link对废胶粉进行改性再生。结果表明，加入3份再生剂De-link，可使废PP/GRT复合材料的冲击强度和拉伸强度有很大的提高；复合材料的冲击断面扫描电镜分析显示，经再生剂改性后复合材料的分散相尺寸明显减小，相容性显著提高。

Abstract：The reclaiming agent De-link was used to improve the mechanical properties of waste propylene/ground tire composite.The results showed that the impact strength and tensile strength of the composite were significantly increased by using 3 phr of De-link ;and it was found from the analysis of impact cross-section on SEM that the size of the continuous phase for the composite modified by De-link was remarkably reduced and the compatibility was also improved.
