摘　　要：研究不同牌号钕系顺丁橡胶(BR)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BR9000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。The application properties of different neodymium butadiene rubber(NdBR)and nickel butadiene rubber(NiBR)in the bead compound of tire were studied.The results showed that,compared with NiBR,the rolling resistance of the NdBR compound was slightly worse,the crosslinking density of the NdBR mix and the tensile strength of the vulcanizate increased,the rolling resistance was reduced,the heat buildup property was better,and other properties were similar.NdBR was suitable for the bead compound of highperformance tire.Comprehensive analysis showed that the compounds with NdBR CB24 and NdBR40 had lower rolling resistance and better heat build-up property.They were suitable for application in the bead compound of low rolling resistance tire.
