| titleOfInvention | A kind of inorganic rare earth oxide black coloring agent and preparation method thereof |
| abstract | The invention relates to a novel inorganic rare earth oxide black colorant and a preparation method thereof. The novel inorganic rare earth oxide black colorant adopts a rare earth compound, a Mn source, a K source, a Ti source and a mineralizer as raw materials and carries out appropriate The weight ratio is a new type of inorganic rare earth oxide black colorant prepared by solid phase synthesis method. It has pure color, does not contain heavy metals such as lead and chromium, is green and environmentally friendly, has good high temperature resistance and good stability. The novel inorganic rare earth oxide black colorant of the present invention can be used in materials such as plastics, paints, and nylon in low-temperature environments, and can also be used in ceramics and high-temperature heat-insulating materials in high-temperature environments above 1000°C. It is non-toxic, green and environmentally friendly, and has excellent performance. Compared with other black colorants such as carbon black, iron black, copper chromium black, etc. in the market, the black colorant of the present invention has better high temperature resistance and wider application range, which makes up for the shortcomings of the existing black colorants generally lacking in high temperature resistance. |
