摘要
文中主要通过对聚氨酯作为成膜物质时其红外性能和物理化学性能研究,通过加入纳米改性填料和改变涂装工艺的方法来降低其红外发射率,同时涂膜具有优良的物理化学性能。通过研究,用聚氨酯作为成膜物质,纳米N iO包覆片状铝粉和SiO2粉等为填料,得到了浅绿色涂层的红外发射率仅为0.39,具有一定的红外隐身与可见光隐身、雷达隐身相兼容效果,同时发现涂层的电导率、磁导率对涂层的红外发射率的影响也很大。
In this paper, polyurethane coatings is selected as infrared stealth film-builder. By the method of adding fillers to polyurethane coatings and changing coatings techniques, low infrared emittance can be gained. Using polyurethane coatings as film-builder and nanometer NiO composite sheet aluminium, SiO2 power and so on as fillers, aqua coat is gotten and its infrared emissivity is 0.39. At the same time it is found that conductance and reluctivity are high effect on infrared emittance of coating.
