| 摘 要： | 使用熔融共混法制备了聚丙烯（PP）／纳米SiO2复合材料。研究发现，硅烷偶联剂对纳米SiO2在PP中的分散起一定的作用，但不是非常有效。添加马来酸酐接枝聚丙烯（PP—g—MAH）相容剂后，可以使纳米SiO2均匀地分散于PP中。当纳米SiO2的质量分数为2％时性能较优，与纯PP相比，V形缺口冲击强度提高了90％，拉伸强度提高了5％，弯曲强度提高了23％。最后，对PP—g—MAH大幅度改善纳米SiO2在PP中分散效果的机理作了初步推断。

| Abstract: | Polypropylene(PP)/nano-SiO2 composites were prepared through direct melt mix processing method.The results showed that silane coupling agent had certain effect on the dispersion of nano-SiO2,and the nano-SiO2 particles were well-distributed in PP matrix when mixed PP-g-MAH acted as compatibilizer.The properties of PP/SiO2 were optimum at 2 % nano-SiO2,compared with pure PP,the Izod impact strength increased 90 %,the tensile strength increased 5 % and the flexural modulus increased 23 %.Finally,the mechanism was deduced on the reason why PP-g-MAH could improve the dispersing effect of nano-SiO2 particles in PP matrix. |
