从基体树脂、填料和涂层综合性能三方面对8~14 μm波段水性红外隐身涂料进行了研究。用红外发射率测量仪测量了涂层在8~14 μm波段的红外发射率，用红外光谱仪测量了树脂红外吸收图谱，用扫描电镜观察了涂层表面形貌。结果表明，丙烯酸树脂在8~14 μm波段有较高的红外透明性，适合做涂料基体树脂；铝银浆能在涂层中形成致密的反射层，适合做红外隐身涂料的填料；填料的粒径、含量和形态都对涂层的发射率有较大的影响；选用钢板为基材，以丙烯酸树脂为基体树脂，粒径2 000目、浮铝百分比为50%的铝银浆为填料，当涂层中填料含量为15%时，测得其发射率为0.34。

Water-based infrared stealth coating in 8-14 μm wavebands was studied from three aspects, matrix resin, filler and the properties of coating. Infrared emissivity in 8-14 μm wavebands was measured by infrared emissometer, infrared absorption was measured by infrared spectrometer(IR), and the surface morphology of the coating was observed by scanning electron microscope(SEM). The results show that acrylic resin are infrared transparent in 8-14 μm wavebands and suitable for matrix resin; the aluminum paste with low infrared emissivity is easily disperse in water-based coating and suitable for filler. The size, content and form of filler are great influence on the emissivity of coating. Steel plate was chosen as a substrate, the acrylic resin as matrix resin. When the size of the aluminum paste is 2 000 mesh, the aluminum paste with 50% leafing aluminum is chosen as the filler, and the content of filler is 15%, the coating infrared emissivity is 0.34.
