中文摘要: |
研究中国石化北京化工研究院燕山分院稀土异戊橡胶(YS-NdIR)的结构和性能并与俄罗斯钛系异戊橡胶进行对比,采用YS-NdIR等量替代天然橡胶(NR)进行试验。结果表明:YS-NdIR具有较高的顺式1,4-结构质量分数和相对分子质量,有利于应变诱导结晶,物理性能较好,其综合性能达到国外同类产品水平。与NR胶料相比,采用YS-NdIR等量替代NR后的胶料具有较好的加工性能,保持了良好的物理性能和动态力学性能。 |
英文摘要: |
The structure and properties of Yanshan Branch rare earth polyisoprene rubber (YS-NdIR) and Russian titanium polyisoprene rubber(SKI-3) were compared,and the properties of compounds with YS-NdIR instead of equivalent NR were investigated.The results showed that,the YS-NdIR possessed higher mass fraction of cis-1,4-units and molecular weight,and better physical properties.The comprehensive properties of YS-NdIR compound and Russian SKI-3 compound were equivalent.The compound of YS-NdIR instead of equivalent NR had good processability,physical properties and dynamic mechanical properties. |
