摘　　要：以丙烯酸改性聚氨酯为粘结剂,CuCoMnOx半导体复合氧化物为颜料,采用喷涂法制备了光谱选择性吸收涂层。考察了颜料与粘结剂的质量比〔简称颜基比(P/B),下同〕、球磨时间、温度、底材和膜层厚度等因素对涂层光热性能的影响。结果表明,颜基比为3∶1,球磨时间9～12 h,Al作底材,膜层厚度1.9μm时所得涂层的吸收率αs=0.936,发射率εT=0.312,αs/εT=3.0。经测定,涂层具有较强的机械性能、耐腐蚀性能和耐候性能。Spectrally selective paint coatings were prepared by spraying method using polyurethane modified by acrylic resin as binder and CuCoMnOx semiconductive compound oxide as pigment.The effect of P/B(pigment/binder) ratio,milling time,temperature,substrates and film thickness on the optical properties of the coatings was investigated.The results show that the solar absorptance(αs) and thermal emittance(εT) of the coatings are 0.936 and 0.312,respectively,and the αs/εT ratio is 3.0 when the P/B ratio is 3∶ 1,the milling time is 9~12 h,the substrate is Al and the thickness is 1.9 μm.The coating also has favorable mechanical behavior,corrosion resistance and weatherability.
