| 中文摘要: |
| 通过调整天然橡胶（NR）/顺丁橡胶（BR）并用比和填料体系优化载重斜交轮胎胎肩垫胶配方，并对胶料性能进行研究。结果表明，NR/BR并用比为85/15、炭黑N550用量为38份、白炭黑用量为10份、硅烷偶联剂用量为2份时，胶料的抗硫化返原性和物理性能较好，压缩生热降低30%以上，成品轮胎的高速性能和耐久性能良好。 |
| 英文摘要: |
| The shoulder wedge formulation for truck bias tire was optimized by adjusting natural rubber（NR）/butadiene rubber（BR） blending ratio and filler system，and the properties of compound were investigated.The results showed that，when the blending ratio of NR/BR was 85/15，the addition level of carbon black N550，silica and silane coupling agent was 38，10 and 2 phr，respectively，the reversion resistant and physical properties of the compound were better，the compression heat build-up was reduced by more than 30%，and the finished tire had good high-speed performance and durability. |
