| 中文摘要: |
| 采用精炼机进行废橡胶的低温力-化学法再生试验，通过调整过辊次数来控制废橡胶的断键解联效果，研究过辊次数对再生橡胶胶料性能的影响。结果表明：随着过辊次数的增大，再生橡胶胶料的门尼粘度、Fmax、FL和交联密度减小， t10和t90缩短，溶胶质量分数增大；当过辊次数为60时，再生橡胶胶料的拉伸强度和拉断伸长率最大。 |
| 英文摘要: |
| The low-temperture mechano-chemical regeneration experiment of the waste rubber was carried out using a refiner machine，the affect of the crosslinking bond breaking and cracking crosslinking of the waste rubber was controlled by adjusting the milling runs，and the influence of milling runs on the properties of the reclaimed rubber compounds was studies.The results showed that，as the milling runs increased，the Mooney viscosity，Fmax，FL and crosslink density of the reclaimed rubber compounds decreased，thet10 and t90 shortened，and the sol mass fraction increased.When the milling runs was 60，the tensile strength and elongation at break of the reclaimed rubber compound were the maximum. |
