稀土异戊橡胶/天然橡胶并用胶性能研究

研究稀土异戊橡胶（NdIR）/天然橡胶（NR）并用胶的性能，并与NR进行对比。结果表明：NdIR/NR并用胶混炼工艺性能、硫化特性和流变性能与NR胶料相当；NdIR/NR并用胶物理性能、耐热空气老化性能、耐切割性能、滚动阻力和动态力学性能与NR硫化胶基本一致，NdIR可部分或全部替代NR。;The properties of NdIR/NR blend were investigated，and compared with those of NR.The results showed that，the mixing behavior，curing behavior and rheological behavior of NdIR/NR blend were similar to those of NR compound；the physical properties，thermal aging property，cut resistance，rolling resistance and dynamic property of NdIR/NR blend also showed no difference from those of NR vulcanizate；so the NdIR could be used to partially or completely replace NR
