摘　　要：研究助交联剂TAIC和HVA-2对硫化剂BIBP硫化氯化聚乙烯(CPE)电缆护套性能的影响。结果表明:加入助交联剂的CPE胶料t10和t90缩短,硫化胶的表观交联密度和剪切储能模量增大;与助交联剂TAIC相比,助交联剂HVA-2会降低胶料的焦烧安全性,提高硫化胶的物理性能和耐热老化性能;采用硫化剂BIBP和助交联剂HVA-2硫化的CPE电缆护套性能达到国家标准要求。The effects of auxiliary crosslinking agents TAIC and HVA-2 on the properties of curing agent BIBP cured CPE cable jacket were investigated. The results showed that, by adding the auxiliary crosslinking agents, the t10 and t90 of CPE compound were reduced, and the apparent crosslink density and shear storage modulus of the vulcanizates increased. Compared to TAIC, the scorch safety of the compound with HVA-2 decreased, and the physical properties and thermal aging property of the vulcanizates were improved. The performance of CPE cable jacket cured with BIBP and HVA-2 met the requirements of national standards.
