| titleOfInvention | A kind of titanium dioxide for decorative paper and preparation method thereof |
| abstract | The invention discloses a titanium dioxide for decorative paper and a preparation method, wherein the titanium dioxide comprises a titanium dioxide base material and a coating layer located on the surface of the titanium dioxide base material, and the coating layer sequentially comprises titanium phosphate and phosphoric acid from the inside to the outside Aluminum mixed coating layer, and magnesium oxide and aluminum oxide mixed coating layer. The titanium dioxide for decorative paper provided by the invention can improve the hue of the titanium dioxide by first coating the surface of the titanium dioxide with a mixed film layer of titanium phosphate and aluminum phosphate, and can reduce the coating process of the titanium dioxide and reduce the cost. Coated with a layer of alumina and magnesium oxide mixed film to increase the isoelectric point of titanium dioxide, so that titanium dioxide is positively charged in the papermaking system, which can better combine with negatively charged cellulose and improve the titanium dioxide in paper. The retention rate is improved, thereby improving the hiding power of titanium dioxide. Based on the above technical solutions, the present invention also provides a method for preparing titanium dioxide. |
