Green porous near-infrared reflection pigment and preparation method thereof

InactiveCN104830139AGood near-infrared reflection performanceImprove insulation performance
The invention discloses a green porous near-infrared reflection pigment and a preparation method thereof. The chemical composition is NaZn[1-x](Cr)xPO4, wherein x is 0.10-0.25. The preparation method comprises the following steps; proportionally dissolving a zinc salt and a chromium salt in deionized water, and stirring at room temperature to obtain a zinc-chromium solution; heating the zinc-chromium solution in a water bath, and slowly and dropwisely adding phosphoric acid while stirring, thereby obtaining a zinc-chromium-phosphorus solution; dissolving sodium carbonate or sodium bicarbonate in water to obtain a sodium solution as a precipitant; slowly and dropwisely adding the precipitant into the zinc-chromium-phosphorus solution to regulate the pH value, standing, washing with water, washing with alcohol, and drying to obtain a precursor powder; and putting the precursor in a muffle furnace, calcining, carrying out furnace cooling, and grinding to obtain the green porous near-infrared reflection pigment. The brightness value of the pigment is 60.27-67.34, and the near-infrared sunlight reflectivity is 63.84-69.12%, which are respectively higher than those of the common iron green pigment. Thus, the green porous near-infrared reflection pigment has wide application prospects in the field of solar heat reflective insulation paints.
