| 摘 要： | 用KH550硅烷偶联剂对铁基合金粉包覆改性,并以其为颜填料制备了雷达/红外兼容隐身单涂层,系统研究了包覆改性对涂层低红外发射率以及雷达吸波性能的影响。研究结果表明,偶联剂以化学键的形式吸附在铁基合金粉表面形成有机薄膜。2%偶联剂包覆对涂层的红外发射率影响较小,但显著降低铁基合金粉的介电常数,提高阻抗匹配度。涂层厚度为2mm时,-10dB的吸收带宽从包覆前1.5GHz增加至2.2GHz,吸收峰强度也有明显增加。

| Abstract: | Fe-based pigment was modified with silane coupling agent(KH550),which was used as filler to prepare radar-infrared compatible stealth coatings.The influence of surface modification on microwave-absorbing properties and infrared emissivity was systematically investigated.The results indicate that Fe-based alloy powders were modified with silane coupling agent successfully.Compared to that of Fe-based alloy powders without modification,the low infrared emissivity of composite coatings treated with 2% coupling... |
