摘　　要：以酰亚胺类、脒类和铵盐类为溴化丁基橡胶(BIIR)硫化体系,通过热失重分析法筛选适合于BIIR的高温硫化体系,并利用BIIR胶料的硫化特性和物理性能等对所筛选的硫化体系进行判定。结果表明,N,N′-间苯撑双马来酰亚胺、N,N′-(4,4′-亚甲基二苯基)双马来酰亚胺和磷酸氢二铵均适合用作BIIR的高温硫化剂。Using imide,amidine and ammonium salt as the vulcanization agents of brominated iso- butylene isoprene rubber （BIIR）, the suitable vulcanization system for BIIR at high temperature was determined by thermo gravimetric （TG） analysis method,and the curing behavior and physical proper- ty of the compound were evaluated. The results showed that,N-N＇ m-phenylene dimaleimide, N, N＇- （4,4＇-methylenediphenyl） dimaleimide and diammonium phosphate were suitable for BIIR curing at high temperature.
