不同品种异戊橡胶的性能对比

对不同品种的异戊橡胶（IR）进行性能对比。结果表明：各种IR胶料的物理性能基本相当，中国石化北京化工研究院燕山分院钛系IR（YS-TiIR）的动态力学性能更为均衡；YS-TiIR以一定比例等量替代天然橡胶（NR）用于载重轮胎胎面胶，胶料的综合性能与俄罗斯SKI-3等量替代NR胎面胶基本相当，其中以30份Ti-IR等量替代NR后，胶料的加工性能和物理性能变化最小。;The properties of different kinds of IR were compared.The results showed that，the physical properties of all IR compounds were equivalent and the dynamic mechanical property of Yanshan branch titanium polyisoprene（YS-TiIR） was more balanced.By using IR instead of equivalent NR in tread compound of truck tire，the comprehensive properties of YS-TiIR compound and Russian SKI-3 compound were mainly equivalent，and with 30 phr titanium polyisoprene instead of equivalent NR，the processability and physical properties of compound had minimum change
