| 中文摘要: |
| 选取2种不同氟含量的氟醚橡胶制备标准O形密封圈（24. 99 mm×3. 53 mm），重点考察2种O形密封圈的物理
性能和耐飞马Ⅱ号、长城4050和FDS-655-HTS航空发动机润滑油性能。结果表明：采用较高氟含量的氟醚橡胶（牌号
VPL85730）制备的O形密封圈在3种航空发动机润滑油中的性能变化不大，而采用较低氟含量的氟醚橡胶（牌号PL855）
制备的O形密封圈仅在飞马Ⅱ号润滑油中的性能保持性较好；当O形密封圈在润滑油中的性能变化较大时，其胶料中炭
黑与橡胶基体会发生脱离。 |
| 英文摘要: |
| Two kinds of low-temperature fluoroether elastomers with different fluorine mass fractions
were selected to prepare standard O-ring seals（24. 99 mm×3. 53 mm）. The physical properties of two O-ring
seals and their resistances to Mobil Oil Ⅱ，Great Wall 4050 and FDS-655-HTS aeroengine lubricating
oils were studied. The results showed that，the properties of the O-ring seals prepared with the fluoroether
elastomer（brand VPL85730） which had a higher fluorine mass fraction had little change in the three kinds of
aeroengine lubricants，while O-ring seals prepared with the fluoroether elastomer（brand PL855） which had
a lower fluorine mass fraction maintained stable property only in Mobil Oil Ⅱ. When the properties of O-ring
seal changed greatly in the aeroengine lubricating oil，a considerable amount of carbon black could separate
from the rubber matrix. |
