Zirconium silicate coated bismuth vanadate yellow pigment and preparation method thereof
According to the zirconium silicate-coated bismuth vanadate yellow pigment disclosed by the invention, zirconium silicate is used as a transparent coating shell to coat bismuth vanadate pigment particles, so that the high temperature resistance of bismuth vanadate is remarkably improved, and higher use requirements are met. In addition, the invention also discloses a preparation method of the zirconium silicate-coated bismuth vanadate yellow pigment, which comprises the following steps: under a liquid phase condition, firstly coating bismuth vanadate pigment particles with a layer of zirconium hydroxide, then coating the zirconium hydroxide with a layer of silicic acid, and finally converting two layers of wrappings into zirconium silicate through high-temperature calcination, thereby obtaining the zirconium silicate-coated bismuth vanadate yellow pigment. Therefore, the zirconium silicate coated bismuth vanadate yellow pigment which is superfine in particle, ultrahigh in coating rate and greatly improved in temperature resistance is obtained, and the application field of the zirconium silicate coated bismuth vanadate yellow pigment is greatly expanded. According to the preparation method, expensive equipment is not needed, the process is simple and easy to operate, influence factors are easy to control, and popularization and application are facilitated.
本发明公开了一种硅酸锆包裹型钒酸铋黄色颜料，以硅酸锆作为透明包裹壳体包裹钒酸铋色料颗粒，从而显著提高钒酸铋耐高温性，并满足更高的使用需求。此外，还公开了上述硅酸锆包裹型钒酸铋黄颜料的制备方法，在液相条件下，首先在钒酸铋色料颗粒外包裹一层氢氧化锆，再在氢氧化锆外包裹一层硅酸，最后通过高温煅烧将二层包裹物转化为硅酸锆，从而获得颗粒超细、包裹率超高、耐温性大幅度提升的硅酸锆包裹型钒酸铋黄色颜料，极大地拓展了其应用领域。本发明制备方法无需昂贵的设备，工艺简单易操作，影响因素易控制，有助于推广和应用。
