Abstract

This application provides a color TiO 2 Near-infrared reflective pigment and preparation method thereof, the chemical formula of the pigment is Ti 1‑m‑ n Fe m Mo n o 2 ; The method includes: Step S1: Equipped with a preset mass fraction of TiO 2 Raw materials, Fe 3+ Impurities and Mo 6+ Impurities; Step S2: Perform ball milling and grinding treatment on the prepared materials in sequence; Step S3: Perform solid-phase synthesis on the grinding material after the grinding treatment, so that the anatase type is completely converted into rutile type; Step S4: The The reactants after the solid phase synthesis are subjected to secondary grinding and sieving to obtain the colored TiO 2 Near infrared reflective pigments. The application can solve the problems of low near-infrared reflectivity, single color, poor energy-saving effect and the like of the existing reflective energy-saving pigments.

Description

technical field [0001] This application relates to the technical field of inorganic oxide near-infrared high reflective materials, in particular to a colored TiO 2 Near-infrared reflective pigment and preparation method thereof. Background technique [0002] Inorganic oxide pigments are widely used in building exterior walls, automobiles, industrial equipment surfaces, plastics, color masterbatches and other fields due to their good temperature and chemical stability, and have broad application prospects. Its spectral reflection characteristic is an important parameter to characterize the performance of various inorganic pigments, and it is also one of its inherent properties. The reflection characteristic in the visible light band (400nm~700nm) of the solar spectrum directly determines the hue and brightness of the pigment; at the near-infrared end of the spectrum (700nm ~2500nm) reflective properties are closely related to the solar heat absorption / reflective properties o...
