摘要
以羰基铁粉作为颜填料,聚氨酯作为树脂基体,制备雷达/红外兼容隐身单涂层,分析羰基铁粉的形态、含量以及球磨时间对涂层红外低发射率以及雷达吸波性能的影响。结果表明:未球磨时,颜填料质量分数为60%,涂层厚为2 mm,在18 GHz处其涂层反射率的最小值达-9.3 dB,其涂层的红外发射率为0.85;球磨16 h,羰基铁粉由球状变为片状,质量分数为60%,其涂层的红外发射率降低至0.69,雷达吸波性能略有降低。羰基铁粉有望成为红外/雷达兼容隐身材料。
The radar-infrared stealthy compatible coatings were prepared with the carbonyl iron particles（CIP） and polyurethane（PU） as fillers and matrix,respectively.The influence of morphology,milling time and content of CIP on microwave-absorbing properties and infrared emissivity was systematically investigated.These results indicate that the minimum reflectivity of microwave-absorbing with thickness of 2 mm reaches-9.3 dB at 18 GHz and infrared emissivity is 0.85 when the content of CIP without mechanical milling is 60%（mass fraction）.After mechanical milling 16 hours,the morphology of CIP is flake.Infrared emissivity decreases to 0.69 when the content of CIP is 60%（mass fraction）,and microwave-absorbing properties decrease slightly.CIP is expected to be infrared-radar stealthy compatible materials.
