冷颜料在红外隐身涂料中的应用
Application of Cold Pigments in Infrared Stealth Coatings
摘要
Abstract
Objective To explore the application of cold pigments in the infrared stealth coatings and reduce the surface temper-ature so as to achieve infrared stealth. Methods XRD diffraction and ultraviolet/visible/near infrared spectrophotometer were used to analyze the phase structure and the near infrared spectral characteristics of pigments. The infrared emissivity measurement instru-ment, the ultraviolet/visible/near infrared spectrophotometer and the infrared lamp simulating sunlight experiment were applied to analyze the infrared emissivity of coatings and the properties of reflectance in heat insulation. Results Compared with the C black pigments, FeCr black pigments had excellent NIR reflectance, its average NIR reflectance was 57% and its reflectance spectral was in accordance with chlorophyll. When the filler content was 10%, FeCr coatings had the best NIR reflectance, which was 39. 2%, and the infrared emissivity was 0. 91. Compared with 20% C coatings and 10% FeCr coatings, the reflection effect of FeCr coatings was obvious and the equilibrium temperature was 8. 8 ℃ lower than C coatings. Conclusion Considering the infrared emissivity of pigments and the need of the color, the content of pigments should be controlled. It was advisable to add 10% mass fraction of pig-ments to meet the requirements of reflective insulation property and the infrared emissivity. Therefore, cold pigment has a certain practical application value and significance.关键词
