酞菁蓝对红外低发射率涂层色泽的影响

Influence of Phthalocyanine Blue on Chromaticity of Low-Infrared-Emissivity Coatings

为了增加红外低发射率涂层的色彩、降低涂层明度和光泽度,采用添加纳米颜料的方法制备了一种蓝色系的红外低发射率涂层。研究了颜料添加量对涂层发射率、涂层颜色和光泽度的影响,并测定了涂层的力学性能和耐中性盐雾腐蚀性能。实验结果表明：涂层在8~14μm时红外发射率为0.3左右;涂层的明度和光泽度均随着颜料添加量增大而降低,颜料添加量为25%的涂层相对于0%添加量的涂层,其明度降低28.8%,光泽度（60°）降低54.5%;并且涂层具有较为优异的力学性能和耐腐蚀性能。

In order to get coatings with low glossiness,bright and polychrome,especially with the property of low infrared emissivity,a novel method for doping the nano pigment is proposed.The influence of the content of nano pigment on emissivity,color and lightness is investigated,moreover the mechanical property and the neuter salt spray resistance property of the coating are studied.The experimental results show that the infrared emissivity in 8—14μm is around 0.3,and the lightness and the glossiness are both decreased with the pigment content increasing.When the content is increased to 25%,the lightness and the glossiness（60°）of the coating are reduced to 28.8%,54.5%,respectively.And,the coating has the relatively excellent mechanical and anti-corrosion properties.
