Molybdenum titanate rare earth cold pigment and preparation method thereof
The invention discloses a molybdenum titanate 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 titanate rare earth cold pigment is RE2 (Ti0. 5Mo0. 5) 3O12. Wherein RE is any one of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc and Y; the preparation method comprises the following steps: carrying out wet ball milling on titanium oxide, molybdenum oxide and rare earth oxide in proportion, and taking zirconium oxide balls and absolute ethyl alcohol as ball milling media; sequentially drying, screening and tabletting the mixture obtained by ball milling to obtain a green body; the green body is sequentially subjected to sintering and heat preservation treatment to obtain molybdenum titanate rare earth ceramic, and then the molybdenum titanate rare earth ceramic is subjected to crushing treatment to obtain the molybdenum titanate rare earth cold pigment.
本发明公开了一种钼钛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，钼钛酸稀土冷颜料的化学通式为RE2(Ti0.5Mo0.5)3O12；其中RE为La、Ce、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb、Lu、Sc、Y中的任意一种；制备方法为：将氧化钛、氧化钼和稀土氧化物按比例进行湿法球磨，以氧化锆球和无水乙醇作为球磨介质；将球磨得到的混合物依次经过干燥、筛分、压片处理后得到坯体；将坯体依次经过烧结、保温处理后得到钼钛酸稀土陶瓷，再将钼钛酸稀土陶瓷经过破碎处理后即得到钼钛酸稀土冷颜料。
