Molybdenum cerium acid rare earth cold pigment and preparation method thereof
The invention discloses a molybdenum cerium acid rare earth cold pigment and a preparation method thereof, relates to the technical field of near-infrared inorganic cold pigment preparation, and solves the problems that the existing cold pigment has certain toxicity and has certain harm to human bodies and the environment, and the general chemical formula of the molybdenum cerium acid rare earth cold pigment is RE2MoCeO7. Wherein RE is at least one element of La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc and Y; the preparation method comprises the following steps: heating a mixed aqueous solution of ammonium molybdate, cerous nitrate, one or more rare earth nitrates, citric acid and ethylene glycol, reacting at a certain temperature to obtain molybdenum cerium acid rare earth-based sol, sequentially carrying out evaporation and drying treatment, and calcining the obtained dry gel to obtain the molybdenum cerium acid rare earth cold pigment. The used rare earth elements have excellent photoelectric properties and low toxicity, and the problem that a transmission inorganic cold pigment has certain harm to human bodies and the environment is solved.
本发明公开了一种钼铈酸稀土冷颜料及其制备方法，涉及近红外无机冷颜料制备技术领域，解决现有的冷颜料带有一定的毒性，对人体和环境存在一定危害的问题，所述钼铈酸稀土冷颜料的化学通式为RE2MoCeO7；其中RE为La、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb、Lu、Sc、Y中的至少一种元素；制备方法为：将钼酸铵、硝酸铈、一种或一种以上的稀土硝酸盐、柠檬酸和乙二醇的混合水溶液加热，在一定温度下反应得到钼铈酸稀土基溶胶，再依次进行蒸发和干燥处理，将得到的干凝胶煅烧，即得钼铈酸稀土冷颜料；使用的稀土元素具有优越的光电性能且低毒，解决了传动的无机冷颜料对人体和环境存在一定危害的问题。
