| 中文摘要: |
| 在70度天然橡胶配方中采用硫磺改性的油膏软化剂和不同粒径强炭黑配合，考察了不同配比对天然橡胶加工性能、动态力学性能和导热性能的影响。结果表明，填充改性油膏后，门尼粘度显著降低，焦烧时间延长约40 s，最高转矩、最低转矩均下降，加工性能变好。另外改性油膏和N774等量填充性能更优，除加工性能外，还具有良好的老化性能、动态力学性能和导热性能。 |
| 英文摘要: |
| The effect of different ratio of sulfur-modified factice softener and carbon black on the processing, dynamic mechanical properties and thermal conductivity was investigated in the 70-degree natural rubber. The results showed that after filling the modified factice, the Mooney viscosity decreased significantly, the scorch time was extended by about 40 s, the highest torque and the lowest torque were both decreased. Apart from processability, the rubber with same filling amount of the modified factice and carbon black N774 have good aging properties, dynamic mechanical properties and thermal conductivity. |
