| 中文摘要: |
| 研究精炼机的辊速比（以下简称辊速比）对再生橡胶胶料性能的影响。结果表明：不同辊速比下，废橡胶再生所受的机械剪切应力分布规律基本相同；随着辊速比的增大，废橡胶再生所受的最大机械剪切应力逐渐增大，再生橡胶胶料的门尼粘度和交联密度逐渐减小，硬度呈先增大后减小的趋势，溶胶质量分数逐渐增大；当辊速比为1.3∶1时，再生橡胶胶料的Fmax－FL、拉伸强度和拉断伸长率最大。 |

| The effect of the roller speed ratios of the refining machine （hereinafter referred to as roller ratios） on the properties of the reclaimed rubber compounds was studied.The results showed that the mechanical shear stress distribution roles of the waste rubber regeneration between two rollers under different roller speed ratios were essentially the same.As the roller speed ratio increased，the maximum mechanical shear stress of the waste rubber regeneration gradually increased，the Mooney viscosity and crosslink density of the reclaimed rubber compounds gradually decreased，the hardness first increased and then decreased，the sol mass fraction gradually increased.When the roller speed ratio was 1.3∶1，the Fmax－FL，tensile strength and elongation at break of the reclaimed rubber compound were the maximum. |
