| 摘 要： | 丁腈橡胶5080（NBR-5080）适用于制造在航空油料中工作的活动或固定密封件和活门件，但HP-8B航空润滑油会引起密封件的收缩造成密封件失效。采用NBR-5080表面施涂氟碳涂层的方法提高其耐油性。通过对比分析丁腈橡胶与含氟碳涂层丁腈橡胶的表面接触角、表面形貌、耐油件及力学性能等，研究丁腈橡胶耐航空润滑油HP-8B的性能。结果表明：氟碳涂层NBR-5080的表而均匀一致、耐油性得到改善、力学性能基本保持不变。

| Abstract: | NBR-5080 can be applied to manufacture seal components and valve components,but HP-8B aviation lubricant may cause the shrinkage of the seal components and lead to their failure.With fluorocarbon coating,the oil-resistance of NBR-5080 can be improved.By contrasting the surface contact angle,surface appearance,oil-resistance and mechanical properties of NBR-5080 without and with fluorocarbon coating,the oil-resistance of NBR-5080 to HP-8B lubricant was investigated.The results show that with fluorocarbon coa... |
