| Abstract: | A blue series of thermal infrared reflective composite pigment was prepared by rutile TiO2 enwrapped with phthalocyanine dye(Direct Fast Turquoise Blue GL),and the enwrapping process of TiO2 was studied.The optimal process conditions were obtained as follows:mass ratio of BaCl2 to TiO2 0.2,reaction temperature 80 °C and pH 8.The infrared reflectivity,thermal insulation property,and acid/alkali resistance of a coating with the composite pigment were examined.Results revealed that the infrared reflectivity of the coating with the blue composite pigment is up to 81.5%,an increase of 37.9% as compared with that of the mixed pigment coating with near color;the bottom temperature of the coating containing composite pigment is about 13.6% lower than that of the coating with cobalt blue pigment,and about 10.6% lower than that of the coating with mixed pigment.The coating with pigments of TiO2 enwrapped by phthalocyanine dye has good acid and alkali resistance. |
