High-temperature-resistant SnO2 coated bismuth vanadate yellow pigment and preparation method thereof
According to the high-temperature-resistant SnO2 coated bismuth vanadate yellow pigment disclosed by the invention, SnO2 is used as a transparent dispersion medium to coat bismuth vanadate pigment particles, so that the high temperature resistance of bismuth vanadate is remarkably improved, and higher use requirements are met. Besides, the invention also discloses a preparation method of the high-temperature-resistant SnO2 coated bismuth vanadate yellow pigment, under a liquid phase condition, reaction conditions are controlled, and a tin source is hydrolyzed by taking high-dispersion bismuth vanadate pigment particles as crystal nucleuses, so that the SnO2 coated bismuth vanadate yellow pigment which is fine in particle, high in coating rate and greatly improved in temperature resistance is obtained. And the application field 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.
本发明公开了一种耐高温SnO2包覆型钒酸铋黄色颜料，以SnO2作为透明分散介质包覆钒酸铋色料颗粒，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，还公开了上述耐高温SnO2包覆型钒酸铋黄色颜料的制备方法，在液相条件下，控制反应条件，使锡源以高分散的钒酸铋色料颗粒为晶核进行水解，从而获得颗粒细小、包覆率高、耐温性大幅提升的SnO2包覆型钒酸铋黄色颜料，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。
