| Abstract: |
| 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. |
