| 中文摘要: |
| 采用自主研发的新型六棱剪切转子密炼机实现废橡胶在低温条件下的再生，并利用五因子四水平的正交试验考察低温密炼工艺参数对废橡胶再生效果的影响。试验得出的低温密炼法最佳再生工艺参数为：剪切混炼时间 12 min，转子转速 60 r·min-1，填充因数 0.75～0.80，压砣压力 0.8 MPa，冷却水温度 40 ℃。在此工艺条件下制得的再生橡胶综合物理性能最佳，再生效果较好。 |
| 英文摘要: |
| The waste rubber could be regenerated at low temperature by using a new hexagonal shear rotor internal mixer developed independently，and the effect of low temperature mixing process parameters on the regeneration of waste rubber was investigated by using the orthogonal test of five factors and four levels.The results showed that，the optimum regeneration process parameters of low temperature internal mixing method were as follows：shear mixing time 12 min，rotor speed 60 r·min-1，filling factor 0.75～0.80，pressure 0.8 MPa，cooling water temperature 40 ℃.Under these conditions，the regenerated rubber has the best comprehensive physical properties and the regeneration effect was good. |
