中文摘要:
      将飞机油箱专用抗静电涂层与不同质量分数二乙二醇甲醚溶液进行浸泡,分析检验涂层在浸泡后的颜色、铅笔硬度、附着力、冲击强度、柔韧性和表面电阻等关键指标的变化情况,用红外光谱、扫描电镜和能谱仪分别检测涂层分子结构、表面形态和元素组成的变化。实验表明:随着二乙二醇甲醚质量分数的不断增加,涂层的力学性能和导静电性能都有不同程度下降:当水相中二乙二醇甲醚的质量分数达到20%,漆膜的导电性能失效,超过60%,漆膜的力学性能失效;当油相中二乙二醇甲醚的质量分数达到0.4%,漆膜的导电性能失效,达到0.6%,漆膜的力学性能失效。结论是二乙二醇甲醚防冰剂在一定条件下会对飞机油箱内壁防静电涂层力学和导静电性能造成不良影响,特殊情况下会造成涂层的脱落。
英文摘要:
      Antistatic coating of aircraft fuel tank is soaked in solution of diethylene glycol methyl ether (DiEGME) to examine the physical and antistatic properties changes of the coating in different proportion such as color, pencil hardness, adhesive force, impact strength, flexibility and surface resistance of the coating tested with different methods, and the FT IR, SEM and EDS are also used to check the molecular structure, surface morphology and element composition of the coating. The results show that with the increase of DiEGME concentration, the mechanical and the electrostatic properties of the coating are on the decrease to a different extent at experiment period. When the concentration of the DiEGME in the water reaches to 20%, the electrostatic conductivity property of the coating is failed, and when the concentration is to 60%, the mechanical property is failed too. When the concentration of the DiEGME in the NO.3 Jet Fuel reaches to 0.4%, the electrostatic conductivity property of the coating is failed, and when the concentration is to 0.6%, the mechanical property is failed too. It is the conclusion that the DiEGME has a poor effect on the mechanical and electrostatic conductivity properties under a certain condition and even makes the coating peeled off under special condition.
