摘要

采用熔融共混法制备了聚丙烯（Polypropylene，PP）/蒙脱土预辐射复合材料，通过X射线衍射（X-ray deffraction，XRD）和透射电子显微镜（Transmission electron microscope，TEM）对复合材料中蒙脱土的分散状态进行了表征，在空气氛围下利用电子束辐照对复合材料进行辐照交联，研究了交联剂在辐照中起的作用和蒙脱土对辐照交联的影响。结果表明：没有加入交联剂的PP不能交联，在PP中加入了蒙脱土以后，在一定的辐照剂量下可以促进PP的交联，含有蒙脱土PP交联体系的力学性能得到大幅度提高。

Abstract

Polypropylene/montmorillonite composite was prepared via melt compounding process. The dispersion of montmorillonite in the composite was analized by XRD (X-ray deffraction) and TEM (Transmission electron microscope). Electronic radiation was applied to make the composite radiation closs-linked in air. The effect of cross-linking agent and montmorillnite on the properties of polypropylene cross-linking was studied. The results indicated that cross-linking did not take place in absence of cross-linking agent, while in presence of both cross-linking agent and montmorillonite polypropylene cross-linking occurred in certain absorbed dose range. The cross-linked polypropylene/momtmorillnite composite exhibited improved mechanical properties.
