高韧性高流动PP合金材料的制备及其性能研究

STUDY ON THE PREPARATION AND PROPERTIES OFSUPER-TOUGHENING HIGH-FLOW-BEHAVIOR PP BLEND

采用三元乙丙胶（EPDM）作为增韧剂，利用自制的熔融指数调节剂（DDCP）与聚丙烯（PP）共混，制备了性能优异的PP合金材料，并对该材料的配比与性能进行了研究。结果表明，PP／EPDM共混合金材料达到了超韧性，而且DDCP能有效地调节共混物的熔融指数，使其能够进行大件的注射成型，适合用作汽车保险杠等材料。

PP blehd material of the high property have been prepared by blending PP with toughening agentEPDM and flow modifying agent-DDCP, and its proportion and properties were studied. The resultsshow that PP/EPDM blends have super-toughening and flow exCellent,its blend is suitable for car speCial material.
