摘要: 本文研究了不同交联剂对PVC辐照交联的影响.交联剂的种类及其在PVC中添加的量都会影响XLPVC的热稳定性,各种机械性能和电性能.实验结果表明TMPTMA是一个比较理想的交联剂.本文还讨论了不同交联剂对溶胶分数和剂量关系的影响,并指出InS和交联剂在PVC中添加的量成正比.

Abstract: Generally, pure PVC can not be irradiation crosslinked by electron beams or α-rays; crosslinking agents (or sensitizers) must be used in the irradiation crosslinking of PVC. The effect of the different sensitizers on irradiation crosslinking of PVC has been investigated. The kind of sensitizer and its content in PVC influence the thermal stability, mechanical properties and electrical properties of XLPVC. Experimental results show that TMPTMA is a better sensitizer for irradiation crosslinking of PVC. Also, the effect of different sensitizers on the relationship.between the sol fraction (S) and dose (R) is discussed. It is found that the logarithmic value of sol fraction (InS) is proportional to the sensitizer content in PVC.
