| 中文摘要: |
| 通过自组装压力设备容器，研究丁腈橡胶在高压海水介质环境下的物理机械性能、动态疲劳性能演变规律。研究结果表明：随着浸泡时间的增加，丁腈橡胶的质量和体积变化率呈现增加的趋势，拉伸强度、拉伸断伸出率呈现降低的趋势；压缩生热量、压缩永久变形随着浸泡时间的增加而降低，且老化温度越高，生热量越小，永久变形越小；随着浸泡时间的增加，丁腈橡胶的阻尼性能降低，老化温度越高，丁腈橡胶阻尼性能越差。 |
| 英文摘要: |
| This paper mainly studied the effect of seawater on the mechanical propertites, dynamical fatigue propertites of Nitrile rubber. The results showed that the quality and volume change ratio of NBR was increased with the increasing of immersion time; tensile strength, tensile elongation at break, compression heat and compression permanent deformation had a trend of decreasement with the increasing of immersion time and the higher the aging temperature, the smaller heat generation and permanent deformation; the damping propertites was decreased with the increasing of immersion time and the aging temperature. |
