| 中文摘要: |
| 研究生物基液体异戊二烯橡胶（LIR-50）对乳聚丁苯橡胶（ESBR）胶料性能的影响。结果表明：与环保芳烃油相比，LIR-50能更好地改善胶料的加工性能；LIR-50参与了胶料的交联反应，可较好地保持胶料的物理性能；加入适量LIR-50能降低胶料的Payne效应，改善炭黑在胶料中的分散性，在保持胶料低滚动阻力和低生热的同时可明显提高其抗湿滑性能。 |
| 英文摘要: |
| The effect of bio-based liquid isoprene rubber （LIR）-50 on the properties of emulsion
polymerized styrene butadiene rubber（ESBR） compound was studied. The results showed that compared
with environmental friendly aromatic oil，LIR-50 could better improve the processability of the compound.
LIR participated in the crosslinking reaction of the compound，which could better maintain the physical
properties of the compound. Adding an appropriate amount of LIR-50 could reduce the Payne effect of the
compound，improve the dispersion of carbon black，and significantly improve the wet skid resistance while
maintaining its low rolling resistance and low heat build-up. |
