| 中文摘要: |
| 研究混炼工艺对防老剂RD残余量及胶料性能的影响。结果表明：在高温处理过程中，防老剂RD发生分解反应，且随着热处理温度的升高，其质量损失增大；防老剂RD在高温（155 ℃）混炼阶段加入比在低温（110 ℃）混炼阶段加入质量损耗增大20%；与在高温混炼阶段加入相比，防老剂RD在低温混炼阶段加入，胶料在老化前的物理性能相当，但是在热老化后的物理性能、耐磨性能和抗切割性能等均得到改善。 |
| 英文摘要: |
| The effect of mixing process on residual antioxidant RD and properties of compound was investigated.The results showed that the antioxidant RD decomposed in the process of high temperature treatment，and its mass loss increased with the rise of heat treatment temperature.The mass loss of antioxidant RD adding at high temperature（155 ℃）mixing stage was increased by 20% to adding at low temperature（110 ℃）mixing stage.Compared with that of adding at high temperature mixing stage，the physical properties of the compound with antioxidant RD adding at low temperature mixing stage were equivalent，but the physical properties，wear resistance and cutting resistance after heat aging were improved. |
