一、前言近代航空工业对高温密封橡胶提出两点要求:一是要求材料在长期高温环境下有良好的弹性,二是与密封介质有满意的相容性。特别是在液压、滑油系统改用双酯和多元醇酯润滑油后,许多胶料都不适应这些介质,仅有氟、氟硅橡胶能兼顾这两方面的要求,因而近年来一些高速飞机上,如 AN20M、37φ2C、37φ3C、JT3D、斯贝等发动机的滑油系统都大量使用了氟橡胶密封件,其使用效果良好,延长了整 First, the preface Modern aviation industry on the high temperature sealing rubber made two requirements: First, require materials in the long-term high temperature environment has good flexibility, the second is sealed media with satisfactory compatibility. Especially in the hydraulic, oil system to use double esters and polyol ester lubricant, many compounds are not suited to these media, only fluorine, fluorine silicone rubber to meet these two requirements, so in recent years some high-speed aircraft , Such as AN20M, 37φ2C, 37φ3C, JT3D, Spey and other engine oil system are extensive use of fluorine rubber seals, the use of good results, the extension of the whole
