以丙烯酸改性聚氨酯为粘结剂,CuCoMnO_x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α_s=0.936,发射率ε_T=0.312,α_s/ε_T=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 CuCoMnO_x 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(α_s) and thermal emittance(ε_T) of the coatings are 0.936 and 0.312,respectively,and the α_s/ε_T 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. |
