| 摘 要： | 选用飞机蒙皮常用的含氟聚氨酯涂层体系为研究对象,结合飞机服役环境的主要特点,开展了实验室模拟加速老化试验研究,并利用电化学阻抗谱对老化试验后的涂层进行了表征.结果表明,紫外线仅对涂层的表面结构产生影响,紫外试验后的涂层电阻下降较慢.在紫外-盐雾循环试验中,紫外线引起涂层表面结构发生变化,涂层的耐水性变差,水更快地进入涂...

| Abstract: | Fluorinated polyurethane coating system commonly applied in aircraft skin was selected as the research object.Laboratory accelerated test of fluorinated polyurethane coatings was carried out according to the main features of environmental factors in service area.The tested coatings were characterized by means of EIS after test.Results showed that UVA effects only on of the coating surface structure;the coating resistance drops slowly after UV test.In UV-salt spray cyclic test,the coating surface structure c... |
