| 中文摘要: |
| 以自制液体异戊二烯橡胶（ZLIR）增塑乳聚丁苯橡胶（ESBR），研究ZLIR用量对ESBR性能的影响，并分别与进口液体异戊二烯橡胶（进口LIR）和芳烃油进行对比。结果表明：ZLIR和进口LIR对ESBR胶料的增塑效果优于芳烃油，其能显著改善ESBR的流动性能，降低胶料的加工能耗，在硫化过程中能参与硫化，是一种反应性增塑剂；与芳烃油相比，ZLIR和进口LIR增塑ESBR硫化胶的300%定伸应力（用量为7，10和15份）和0 ℃下的tanδ较大，压缩疲劳温升、Payne效应、60 ℃下的tanδ<、i>和阿克隆磨耗量较小。ZLIR与进口LIR对ESBR胶料综合性能的影响基本相近。 |

| The self-made liquid isoprene rubber(ZLIR) was used to plasticize ESBR，and the effects of addition levels of ZLIR，aromatic hydrocarbon oil and imported liquid isoprene rubber(ILIR) on the properties of ESBR compound were investigated.The results showed that，the plasticizing effect of ILIR and ZLIR on ESBR compound were superior to aromatic hydrocarbon oil，ILIR and ZLIR could significantly improve the processing flow property of ESBR and reduce the processing energy consumption，and they were reactive plasticizers and could be co-crosslinked with ESBR during vulcanization.Compared with aromatic hydrocarbon oil plasticized ESBR，the modulus at 300% elongation and tanδ at 0 ℃ of ZLIR or ILIR(7，10，15 phr) plasticized ESBR vulcanizates were higher，the compression temperature rise，Payne effect，tanδ at 60 ℃ and Akron abrasion loss were lower.The influences of ZLIR and ILIR on the comprehensive performance of ESBR compound were substantially similar. |
