| 中文摘要: |
| 研究不同牌号钕系顺丁橡胶与镍系顺丁橡胶（BR9000）在轮胎胎圈胶中的应用性能。结果表明，与镍系BR相比，钕系BR加工性能略差，混炼胶交联密度增大，硫化胶拉伸强度增大，滚动阻力降低，生热性能较优，其他性能相当，适用于高性能轮胎胎圈胶。综合分析，钕系BR CB24和BR40具有更低的滚动阻力和较优的生热性能，适合应用于低滚动阻力轮胎胎圈胶中。 |
| 英文摘要: |
| The properties of different neodymium butadiene rubber（NdBR）and nickel butadiene rubber（NiBR）in bead compound of tire were studied.The results showed that，compared with NiBR，the rolling resistance of NdBR was slightly worse，the crosslinking density of mix and the tensile strength of vulcanizate were increased，the rolling resistance was reduced，the heat build-up property was better，and other properties were similar.NdBR was suitable for high-performance tire bead compound. Comprehensive analysis showed that NdBR CB24 and NdBR40 had lower rolling resistance and better heat build-up property.They were suitable for application in bead compound of low rolling resistance tire. |
