| 中文摘要: |
| 利用硫化机对废旧轮胎胶粉进行再生，研究脱硫温度、脱硫时间和脱硫压力对再生橡胶门尼粘度和物理性能的影响。结果表明：随着脱硫温度的升高，再生橡胶的门尼粘度减小，硫化再生橡胶的拉伸性能先提高后降低；随着脱硫时间的延长或脱硫压力的增大，再生橡胶的门尼粘度减小，硫化再生橡胶的拉伸性能下降。当脱硫温度为250 ℃、脱硫时间为10 min、脱硫压力为2. 5 MPa时，再生橡胶的综合性能较好。 |
| 英文摘要: |
| The waste tire rubber powder was regenerated by vulcanizing machine，and the influence of desulfuration temperature，time and pressure on the Mooney viscosity and physical properties of reclaimed rubber powder was studied. The results showed that，as the desulfuration temperature increased，the Mooney viscosity of the reclaimed rubber decreased，and the tensile properties of the vulcanized reclaimed rubber increased at first and then decreased. As the desulfuration time was extended or pressure increased，the Mooney viscosity of the reclaimed rubber decreased，and the tensile properties of the vulcanized reclaimed rubber decreased. When the desulfuration temperature was 250 ℃，the desulfuration time was 10 min，and the desulfuration pressure was 2. 5 MPa，the overall properties of the reclaimed rubber were better. |
