Production method of high-gloss and high-covering-capability rutile titanium dioxide

The invention discloses a production method of high-gloss and high-covering-capability rutile titanium dioxide. The production method comprises the steps of preparing metatitanic acid slurry, sequentially adding a magnesium-containing compound, a zirconium-containing compound and a potassium-containing compound to prepare titanium dioxide primary slurry, then sequentially adding a titanium-containing compound and an aluminum-containing compound, and finally filtering, washing, drying and crushing to obtain high-gloss and high-covering-capability rutile titanium dioxide. According to the production method, saline matters such as magnesium salt, zircon salt, kali salt and the like are added in metatitanic acid, so that the effect of improving the high covering property of titanium dioxide can be achieved; and the surface treatments of hydration of titanium dioxide and hydration of titanium dioxide, and the like can be conducted on the surface of titanium dioxide, so that the effect of improving the gloss of titanium dioxide can be achieved, and the gloss and the covering capability of titanium dioxide are all improved greatly.
