| 中文摘要: |
| 以预分散炭黑/天然橡胶母胶和一段混炼胶的排胶温度、填充因数和转子转速为因子，采用正交试验设计方法研究炭黑预分散混炼工艺在全钢载重子午线轮胎胎面胶生产中的应用。结果表明，与常规混炼工艺相比，采用炭黑预分散混炼工艺胶料的炭黑分散性提高，物理性能和耐老化性能改善，成品轮胎的耐久性能和高速性能提高，退赔率下降。 |
| 英文摘要: |
| The application of mixing process of predispersed carbon black in the tread compound production of truck and bus radial tire was investigated by orthogonal experimental design.The discharging temperature，filling factor and rotor speed of the mixing processes for the predispersed carbon black/NR masterbatch and first stage compound were applied as factors.The results showed that，compared with general mixing process，the dispersion of carbon black by using predispersed mixing process was improved，the physical properties and aging resistance of the tread compound were improved，the endurance performance and high speed performance of the finished tire were enhanced，and the claim rate decreased. |
