| 中文摘要: |
| 选用高饱和度低丙烯腈含量的氢化丁腈橡胶（HNBR），通过机械混炼的方法加入不同量的碳纳米管（CNTs），研究CNTs用量对HNBR的物理性能、高温拉伸性能、耐磨性能和低温性能的影响。结果表明，加入CNTs使胶料拉伸强度和定伸应力有不同幅度的提高，对拉断伸长率有降低作用，可提高胶料的高温拉伸强度、耐磨性能和耐低温性能，使HNBR产品适应更严苛的工况。结合使用工况利用CNTs的取向性有助于提高产品性能。 |
| 英文摘要: |
| Selecting hydrogenated nitrile rubber （HNBR） with high saturation and low acrylonitrile content，adding different amounts of carbon nanotubes （CNTs） through mechanical mixing，and the effect of amount of CNTs on the physical properties，high temperature tensile properties，wear resistance and low temperature properties of HNBR was studied.The results showed that CNTs could improve the tensile strength and modulus of compound in different ranges，reduce the elongation at break，and improve the high temperature tensile strength，wear resistance and low temperature properties of the compound，so that HNBR products could adapt to more severe working conditions.The orientation of CNTs could be used in combination with the working conditions to improve product performance. |
