| 目的 研究FX-4和FX-17典型橡胶密封圈的加速老化性能。方法 对初始压缩率为14%和20%的FX-4和FX-17这2种橡胶密封圈，进行5个温度点不同时长的加速老化试验，通过试验测定FX-4和FX-17橡胶密封圈的拉伸强度、扯断伸长率、硬度以及压缩永久变形等4个性能指标，并进行分析和比较。结果 硬度指标随老化温度以及老化时间的变化不明显。拉伸强度与扯断伸长率在200 ℃老化试验后，均出现明显的下降趋势，但在同一老化温度下老化10、70 d后，拉伸强度与扯断伸长率未发生明显的变化。在较低的老化温度时，压缩永久变形率随老化温度以及老化时间的变化不明显；在150、200 ℃温度老化后，压缩永久变形率随着老化时间的增加而呈上升趋势。结论 FX-4与FX-17橡胶密封圈的压缩永久变形率在老化温度点较低时，受温度的影响不显著，在同一温度下随老化时间的增加呈上升趋势；在老化温度点较高时，压缩永久变形率随着老化时间的增加而呈上升趋势。 |

| The work aims to study the accelerated aging performance of FX-4 and FX-17 typical rubber seals. During initial compression rates of 14% and 20% and different duration of accelerated aging at five temperature points, four performance parameters of FX-4 and FX-17 rubber sealing rings, including tensile strength, elongation at break, hardness, and compression permanent deformation, were tested, analyzed and compared. The hardness index did not change significantly with aging temperature and aging time. After aging test at 200 ℃, both tensile strength and elongation at break showed an obvious downward trend, however there was no obvious change in tensile strength and elongation at break after aging for 10 and 70 days at the same temperature. The change of compression permanent deformation rate with aging temperature and aging time was not obvious at low aging temperature point. After aging at 150 ℃ and 200 ℃, the compression permanent deformation rate increased with the aging time. The compression permanent deformation rate of FX-4 and FX-17 rubber sealing rings is not significantly affected by temperature at low aging temperature points, but shows an upward trend with the increase of aging time at the same temperature. At high aging temperature points, the compression permanent deformation rate shows an upward trend with the increase of aging time. |
