摘　　要：研究了硫化促进剂异氰尿酸三烯丙酯(TAIC)、N,N′-间苯撑马来酰亚胺(PDM)和硫黄(S)对氢化丁腈橡胶(HNBR)硫化特性和力学性能的影响。结果表明,含PDM的胶料t10和t90均最短,交联效率较高,力学性能最好;PDM用量为1.5份到3份时能有效提高HNBR胶料的耐热氧老化性能。DCP用量为10份时,增加PDM用量可有效提高HNBR的交联程度,缩短交联时间。In this paper,the effects of curing coagents TAIC,PDM and S on the curing characteristics and mechanical properties of HNBR compound were studied.The results showed that the HNBR compound cured by PDM had the shortest scorch time and optimum curing time,and the crosslink efficiency was high,and the mechanical properties were best.The thermal aging properties were improved when PDM contents increased from 1.5 phr to 3 phr.When DCP content was 10 phr,the crosslink degree of HNBR blend increased with the increase of PDM content,and the optimum curing time decreased.
