| 中文摘要: |
| 研究混炼工艺对白炭黑填充胶料中防老剂6PPD损耗的影响。将防老剂6PPD在二段混炼时加入，一段混炼保持温度为145 ℃且恒温200 s，二段混炼无恒温直接排胶，可以避免一段混炼时高温环境对防老剂的分解，有效降低防老剂6PPD的损失，改善白炭黑的分散，制备的胶料兼具良好的抗湿滑性能和较低的滚动阻力。 |
| 英文摘要: |
| The effect of the mixing process on the loss of antioxidant 6PPD in silica-filled compounds was studied.Adding antioxidant 6PPD during the second stage mixing，the first stage mixing was maintained at a temperature of 145 ℃ and at a constant temperature for 200 s，the second stage mixing did not have a constant temperature and directly discharged the compound，which could avoid the decomposition of antioxidant in the high temperature environment during the first stage mixing，effectively reduce the loss of antioxidant 6PPD and improve the dispersion of silica.The compound exhibited both good wet skid resistance and low rolling resistance. |
