摘要
利用硅烷交联的工艺方法制备了高密度聚乙烯(HDPE)热收缩材料,研究了引发剂过氧化二异丙苯(DCP)和过氧化二特丁烷(DTBP)含量的变化对复合热收缩材料拉伸强度、断裂伸长率、维卡软化点、凝胶含量和热收缩率的影响。结果表明:通过试验确认了当引发剂加入0.12份时,制备出来的复合热收缩材料综合性能最好。相比之下,DTBP作为引发剂对复合体系性能影响效果更显著。
The HDPE thermal shrinkable materials were prepared by silane crosslinking.The effects of the contents of DCP and DTBP on the tensile strength,elongation at break,softening point,gel content and thermal shrinkage of the composite thermal shrinkable materials were studied.The results showed that the composite heat shrinkable material had the best comprehensive performance when 0.12 initiator was added.In contrast,the effect of DTBP as initiator on composite system performance is more significant.
