摘　　要：研究钕系顺丁橡胶(Nd BR)在全钢载重子午线轮胎胎面胶[天然橡胶(NR)/顺丁橡胶(BR)并用胶]中的应用。结果表明:在全钢载重子午线轮胎胎面胶中采用Nd BR(BR CB22和BR CB24)等量替代镍系顺丁橡胶(Ni BR)(BR9000),胶料的F_(max)较大,t_(90)和t_(100)延长,抗硫化返原性能改善,拉伸性能、抗撕裂性能、耐磨性能、耐老化性能和耐疲劳性能提高,动态生热和压缩疲劳生热降低;与采用BR CB24的胎面胶相比,采用BR CB22的胎面胶的动态生热和压缩疲劳生热更低,综合性能更好;采用BR CB22的胎面胶的成品轮胎滚动阻力降低。The application of neodymium-based butadiene rubber（Nd BR） in the natural rubber（NR）/butadiene rubber（BR） blend based tread compound of truck and bus radial tire was studied. The results showed that when Nd BR（BR CB22 and BR CB24） was applied to replace nickel-based butadiene rubber（Ni BR）（BR9000） at equal weight,the Fmax of the tread compound increased,t90 and t100 were extended,the anti-reversion property was improved,the tensile properties,tear resistance,wear resistance,aging resistance and fatigue resistance were improved,and the dynamic heat build-up and the compression fatigue temperature rise were reduced. Compared with the tread compound with BR CB24,the dynamic heat build-up and the compression temperature rise of the tread compound with BR CB22 were lower,and overall performance was better. The finished tire with the tread compound containing BR CB22 possessed reduced rolling resistance.
