In addition, in order to solve the above-mentioned problem of poor water dispersibility, for example, chinese patent application No. 201811042416.4 discloses a preparation method of microspherical composite titanium dioxide for paint, which comprises preparing a mixed solution a containing sodium polystyrene sulfonate and calcium chloride, mixing with ammonium bicarbonate to form a mixed solution B, reacting to prepare sodium polystyrene sulfonate composite microspheres coated with calcium carbonate, and reacting with tetrabutyl titanate to prepare a sodium polystyrene sulfonate-calcium carbonate-titanium dioxide composite material, i.e. microspherical composite titanium dioxide for paint. For another example, Chinese patent application No. 201710338990.3 discloses a surface treatment method of nano titanium dioxide applied to decorative paper, which comprises the steps of conveying the nano titanium dioxide to a surface treatment tank, adding a glyceryl stearate dispersant and water, controlling the temperature at 50-70 ℃, and stirring at the rotation speed of 300-500r/min for 10-20min to obtain a nano titanium dioxide dispersion liquid; adding the nano titanium dioxide dispersion liquid into an ultrasonic generator, adding an alkyl naphthalene sulfonate and polyacrylamide composite modifier, and performing ultrasonic treatment at 50-70 ℃ and 50-70KHz for 30-60min to obtain a modified nano titanium dioxide liquid; and filtering, drying, crushing and sieving the modified nano titanium dioxide solution to complete the surface treatment of the nano titanium dioxide.
The schemes are good exploration for the problems of titanium dioxide dispersibility and dust emission, but still have space for further improvement, and research on titanium dioxide in the industry is never stopped.
