| 中文摘要: |
| 研究两种国产稀土顺丁橡胶（NdBR）Nd-40和Nd-60分别在全天候轮胎和冬季轮胎胎面胶中的应用性能，并与传统镍系顺丁橡胶（BR9000）进行对比。结果表明：与BR9000相比，两种NdBR与填料的结合能力较好，加工工艺性能可满足现场生产要求；两种NdBR硫化胶的综合物理性能和耐热老化性能较优，抗湿滑性能相近，滞后损失小，生热低，成品轮胎的高速和耐久性能均符合产品设计要求；在全天候轮胎胎面胶中加入Nd-40，硫化胶的耐磨性能提高，成品轮胎的滚动阻力降低。 |
| 英文摘要: |
| The application of two kinds of domestic NdBR（Nd-40 and Nd-60） in the tread compound of all season tire and winter tire was investigated，respectively，and compared with traditional NiBR（BR9000）.The results showed that，compared with BR9000，the binding properties of these two kinds of NdBR and filler was better，processing property could meet the production requirements，comprehensive physical properties and heat aging resistance of the vulcanizates were improved，wet sliding resistance was similar，hysteresis loss was decreased，heat build-up was lower，and high speed performance and durability of the finished tire met the product design requirements.By adding Nd-40 in the tread compound of all season tire，the wear resistance of the vulcanizates was improved，and rolling resistance of the finished tire was reduced. |
