溴化丁基橡胶的硫黄硫化反应动力学研究

研究溴化丁基橡胶（BIIR）的硫黄硫化反应动力学。结果表明：硫黄/促进剂DM、硫黄/氧化锌、硫黄、硫黄/促进剂DM/氧化锌的硫化速率常数依次增大；硫黄、硫黄/促进剂DM、硫黄/氧化锌和硫黄/促进剂DM/氧化锌硫化反应活化能依次减小；硫黄/促进剂DM/氧化锌硫化BIIR硫化胶的综合物理性能较好，协同硫化作用明显。;The sulfur vulcanization kinetics of BIIR was investigated.The results showed that，the curing rate constant increased in the order of sulfur/accelerator DM curing systemsulfur/accelerator DM>sulfur/zinc oxide>sulfur/accelerator DM/zinc oxide.The comprehensive physical properties of BIIR vulcanized by sulfur/accelerator DM/zinc oxide were the best，while sulfur and the co-agents showed a significant synergetic effect on the vulcanization
