| 中文摘要: |
| 研究几种聚丁二烯橡胶（BR）在半钢子午线轮胎胎圈胶中的应用。结果表明：BR-B胶料兼顾补强性能和滞后损失，综合性能优异；CB24和BR-A胶料的滞后损失小，有利于降低生热，改善胎圈部位的使用性能；VCR412的补强性能最佳，在不考虑生热的情况下是胎圈胶配方较佳的选择；CB60在对比的几种BR中生热最高。 |
| 英文摘要: |
| The application of different polybutadiene rubber in the bead compound of steel-belted radial tire was investigated.The results showed that，BR-B compound had excellent comprehensive properties，considering both reinforcing performance and hysteresis loss.CB24 and BR-A compound had small hysteresis loss，which was beneficial to reduce heat build-up and improve the service performance of bead.VCR412 had the best reinforcing performance，and was the better choice of bead compound formula without considering heat build-up.CB60 had the highest heat build-up in the several comparative BR. |
