Appl. No.:

11/600643

International Classification:

C09C 3/06

US Classification:

106438, 106436, 106437, 423598, 427215, 427218

Abstract:

An improved process is described for manufacturing zirconia-treated titanium dioxide pigments, wherein the zirconia treatment is accomplished in the process of fluidizing a titanium dioxide filter or press cake and then drying the same, through the addition to the filter or press cake of one or more alkaline water-soluble zirconium reagents selected from ammonium zirconyl carbonate, the water-soluble ammonium zirconyl carboxylates and mixtures of these. Aqueous solutions of such zirconium reagents, in addition to being effective for imparting a zirconia surface treatment to the titanium dioxide materials, also prove to be effective fluidizing agents for forming high solids dispersions of the zirconia-treated titanium dioxide pigment materials which can be spray dried without substantial dilution and excessive energy requirements.

Abstract:

An improved process for making an organosilicon compound surface-treated titanium dioxide material, comprising (a) forming a mixture of the titanium dioxide material in water, (b) wet milling the mixture, (c) adjusting the pH of the slurry resulting from step (b) to between about 5. 0 and about 8. 5, (d) after step (c), removing the titanium dioxide material from the mixture by vacuum or pressure filtration, (e) after step (d), washing the titanium dioxide material so removed, (f) after step (e), converting the washed titanium dioxide material to a fluid dispersion having a pH of from about 3. 5 to less than about 7 via addition of a fluidizing agent comprising a water-soluble monoprotic acid, (g) after, or concurrently with, step (f), adding to the resulting dispersion of titanium dioxide material an organosilicon compound, with mixing, and (h) spray drying the dispersion of the washed titanium dioxide material resulting from step (g) to yield a dry titanium dioxide pigment powder.
