选择不同粘度的料浆制得涂层, 探究粘度对于涂层各性能的影响。对制得的涂层进行表面观察, 采用发射率仪、色差仪及光泽度仪分别对其发射率、明度及光泽度进行测试, 并采用 SEM对涂层表面形貌进行分析, 最后测试涂层的力学及耐盐雾性能。结果表明: 当料浆粘度在 15～20 s时, 涂层表面状况较好, 铝粉可以被炭黑粒子均匀地覆盖, 涂层明度约为 53, 光泽度低至 6.5, 改变颜色的同时仍满足低发射率的要求, 约为 0.14, 且涂层具有优异的力学性能及耐盐雾性能。

Coatings were prepared by the slurry with different viscosity and the properties were studied. The coating surface was observed, and the emissivity, chroma and glossiness were measured by the infrared emissivity meter, colorimeter and glossiness instrument, respectively. Then the surface morphology of the coatings was characterized by SEM. The result shows that when the viscosity is between 15s and 20s, the coating surface is in good condition, and the aluminum powder can be uniformly covered with carbon black particles. The lightness of coating is about 53 and the glossiness is low to 6.5.The coatings still maintain low infrared emissivity after the color changed, and the emissivity was about 0.14,and both mechanical properties and salt spray resistance of the coating are excellent.
