摘　　要：以微米镍粉和丙烯酸乳液为原料制备复合导电涂料,研究了涂料中镍粉和水的含量以及涂层厚度对涂膜微波反射率的影响,并分析了涂膜的微观结构。结果表明,当镍粉含量为40%～50%、水为20%～30%时,所得涂膜中镍粉分散均匀;当涂层厚度为(140±8)μm时,涂膜在频率为2～18GHz范围内的微波反射率最高,达到铝板的60%～70%。The composite conductive coating was prepared with micron nickel powders and acrylic latex as materials.The influence of the contents of nickel powders and water and coating thickness on the microwave reflection of film was studied.The microstructure of the film was analyzed.The results indicated that the nickel powder disperses uniformly,when nickel powder content is 40%-50% and water 20%-30%.The microwave reflectivity of film is the highest over a frequency range of 2-18 GHz,which reaches 60%-70% of aluminum board,when the film thickness is 140±8 μm.
