| 中文摘要: |
| 研究稀土顺丁橡胶（NdBR）/丁苯橡胶并用对半钢子午线轮胎胎面胶性能的影响。结果表明：含BR9110A，BR9110B和BR CB24（3种NdBR）的胶料性能基本接近；用乳聚丁苯橡胶部分替代溶聚丁苯橡胶和NdBR，可以改善胶料的生热性能，提高抗切割性能和抗湿滑性能；采用母炼胶工艺可以明显改善胶料的综合物理性能，提高抗切割性能、抗裂口增长性能和抗湿滑性能，降低滚动阻力。 |
| 英文摘要: |
| The effect of neodymium butadiene rubber（NdBR）/styrene butadiene rubber（SBR） blending on the properties of the tread compound of steel-belted radial tire was studied. The results showed that the properties of the compound containing three kinds of NdBR（BR9110A，BR9110B and BR CB24） were almost the same，and the heat build-up，cutting resistance and wet skid resistance of the compound could be improved by partially replacing solution styrene-butadiene rubber and NdBR with emulsion styrenebutadiene.By using masterbatch process，the comprehensive physical properties of the compound could be significantly improved，the cutting resistance，crack resistance and wet skid resistance increased，and the rolling resistance decreased. |
