| 中文摘要: |
| 研究液体1，4-聚丁二烯（LPB）在丁苯橡胶胶料中的应用。结果表明：LPB的微观结构主要为顺式-1，4-结构和反式-1，4-结构；采用LPB作为增塑剂替代环保芳烃油（TDAE），胶料的 t10和t90延长，硫化胶的耐磨性能提高，滚动阻力降低，但同时抗湿滑性能下降；以LPB等量替代TDAE，硫化胶的拉伸性能下降，以LPB部分替代TDAE，硫化胶的拉伸性能提高。 |
| 英文摘要: |
| The application of liquid 1，4-polybutadiene（LPB） in styrene butadiene rubber（SBR） compounds was studied.The results showed that the microstructure of LPB mainly consisted of cis-1，4-structure and trans-1，4-structure.Using LPB as a plasticizer to replace environmentally friendly aromatic oil（TDAE），the t10 and t90 of the compound were extended，the wear resistance of the vulcanizate increased，and the rolling resistance decreased，but at the same time，the wet slip resistance was reduced.Replacing TDAE with an equal amount of LPB resulted in a decrease in the tensile properties of the vulcanizate, while partially replacing TDAE with LPB resulted in an improvement in the tensile properties of the vulcanizate. |
