| titleOfInvention | Porous near-infrared reflection pigment of green and preparation method thereof |
| abstract | The present invention discloses a kind of green porous near-infrared reflection pigment and preparation method thereof, and chemical composition is NaZn 1‑x (Cr) x PO 4 , wherein x is 0.10~0.25.Preparation method comprises the following steps：Zinc salt and chromic salts are dissolved in deionized water in proportion, stirred at room temperature, zinc chrome solution is obtained；By the zinc chrome solution heating water bath, stirring is slowly added dropwise phosphoric acid simultaneously, obtains zinc chrome phosphorus solution；Water is dissolved in using sodium carbonate or sodium acid carbonate, sodium solution is obtained, is used as precipitating reagent；The precipitating reagent is slowly added dropwise into zinc chrome phosphorus solution, pH value is adjusted, stood, washing, alcohol is washed, dries, obtains precursor powder；The precursor powder is placed in Muffle furnace, calcined, furnace cooling, grinding obtains the green porous near-infrared reflection pigment.The pigment brightness value of the present invention is 60.27~67.34, and near-infrared sun light reflectivity is 63.84%~69.12%, is above common iron green pigment, is had broad application prospects in solar heat reflecting and heat insulating coating field. |
