| 中文摘要: |
| 研究炭黑改性低顺式聚丁二烯橡胶（LCBR）在缺气保用轮胎支撑胶中的应用。结果表明：采用炭黑改性LCBR替代顺丁橡胶，胶料的硫化特性变化不大，焦烧时间延长，加工性能略有下降；定伸应力有所提高，拉伸强度和拉断伸长率变化不大；生热大幅降低；采用炭黑改性LCBR制备的缺气保用轮胎的零气压耐久性能更好。 |
| 英文摘要: |
| The application of carbon black modified low cis-polybutadiene rubber（LCBR） in side insert compound of run-flat tire was studied.The results showed that using carbon black modified LCBR instead of butadiene rubber，the curing characteristics of the compound changed a little，the scorch time was prolonged，the processing properties was slightly decreased，the modulus was improved，the tensile strength and elongation at break changed a little，the heat build-up was greatly reduced.The zero-pressure endurance of the run-flat tire built by carbon black modified LCBR was better.Therefore, this paper studies the application of a carbon black modified low cis polybutadiene rubber in side insert rubber formula, and the results show that its vulcanizate modulus is higher, its heat generation is lower, and its zero air pressure durability is longer. |
