Preparation method of blue pigment for coating/ink-jet printing/nano-zirconia ceramic
The invention discloses a preparation method of a blue pigment for coating/ink-jet printing/nano-zirconia ceramic. The preparation method for synthesizing the blue pigment by adopting a semi-liquid and semi-solid phase process disclosed by the invention comprises the following steps of: adding cobalt, aluminum and other metal salts and alkali or alkali metal salt dropwise into water at the same time, and conducting filter pressing, washing and drying to obtain a nano-precursor, uniformly mixing the precursor with rare earth compounds doped with co-stability yttrium and the like, white carbon black and a mineralizing agent according to a certain mass ratio, and performing calcining at 900DEG C-1000DEG C to obtain the blue pigment for coating/ink-jet printing/nano-zirconia ceramic. Accordingto the invention, the precursor is subjected to nanocrystallization, the high-temperature crystal transformation temperature is reduced to 900DEG C-1000DEG C from the original 1280DEG C, the materialafter crystal transformation directly reaches 2 microns or less without mechanical refining D50, the integrity, high specific surface area and stable chemical properties of the material are kept, andthe performance requirements of the fields of coatings, ink-jet printing, zirconia ceramics and the like are met.
本发明公开了一种涂料/喷墨打印/纳米氧化锆陶瓷用蓝色颜料的制备方法，包括采用半液半固相工艺合成蓝色颜料的制备方法。本发明的制备方法为：将钴、铝等金属盐与碱或碱金属盐同时滴入水中，经压滤水洗烘干后获得纳米化前驱体，将前驱体与掺杂助稳定性钇等稀土化合物、白炭黑、矿化剂按一定质量比混合均匀之后在900℃‑1000℃下煅烧获得涂料/喷墨打印/纳米氧化锆陶瓷用蓝色颜料。本发明通过对前驱体的纳米化，使得高温转晶的温度由原来的1280℃降低至900℃‑1000℃，转晶后物料不需机械细化D50直接达到2微米以内，保持物料的完整性、高比表面及稳定的化学性，符合涂料、喷墨打印、氧化锆陶瓷等领域的性能要求。
