无机粒子/EPDM填充聚丙烯的研究

Research of PP Filled with Inorganic Particles and EPDM

分别采用了白炭黑、滑石粉及高岭土等无机粒子与EPDM弹性体配合对聚丙烯进行填充改性,对各种改性体系的力学性能、耐热性能及加工性能进行了研究,并用扫描电镜对共混物进行结构表征。结果表明:采用PP/EPDM/白炭黑配方为100∶15∶15时,共混物的综合性能最好。

PP was modified by EPDM and inorganic particles such as white carbon black, talcum powder and kaolin. The mechanical and thermal properties of the modified PP, as well as the processability, were studied. The structures of blending polymers were characterized by SEM. The results showed that the combination property of blending polymers would be the best with a formula of PP/EPDM/white carbon black = 100/15/15.
