| 中文摘要: |
| 研究硫黄/促进剂（TBBS）用量比（简称硫/促比）对丁腈橡胶胶料性能的影响。结果表明：随着硫/促比的减小，混炼胶的门尼粘度、t10和FL变化不大，t90先缩短后延长，Fmax和Fmax－FL逐渐减小；硫化胶的硬度、定伸应力、拉伸强度和撕裂强度逐渐减小，拉断伸长率和回弹值逐渐增大；硫/促比对混炼胶的频率扫描和应变扫描结果影响不大，硫化胶的储能模量随硫/促比的增大而增大，损耗因子随硫/促比的增大而减小。 |
| 英文摘要: |
| The effect of sulfur/accelerator （TBBS） dosage ratio on the properties of nitrile rubber
（NBR）compound was studied. The results showed that，with the decrease of sulfur/accelerator dosage ratio，
the Mooney viscosity，t10 and FL of the mixed compound changed little，t90 was shortened first and then was
extended，FmaxandFmax－FLdecreased gradually，the hardness，modulus，tensile strength and tear strength
of the vulcanizate decreased gradually，and the elongation at break and rebound value increased gradually.
The sulfur/accelerator dosage ratio had little effect on the test results of dynamic property measurement
of the mixed compound in the frequency scanning test or strain scanning test. The storage modulus of the
vulcanizate increased with the increase of sulfur/accelerator dosage ratio，and the loss factor decreased. |
