Solar Reflection Characteristics of Phthalocyanine Green/TiO₂ Composite Green Pigments Prepared via Different Approaches

Abstract:

Near-infrared pigment is the key to control the near-infrared performance of solar heat-reflective coating which has good economic and application prospects as a new special coating. Green infrared reflective pigments were prepared through physical mixing, inorganic lake method and sol-gel processes in this study. Results show that the near-infrared spectral reflectance of composite pigments is improved when using inorganic lake method and sol-gel method. Chromaticity of composite pigment is the closest to phthalocyanine green when using sol-gel method. Physically mixing method is not suitable to prepare infrared reflective pigment. The coating materials have influence on the coating effect and the reflectivity of near-infrared spectral range in a certain extent.
