| titleOfInvention | Production method of titanium dioxide with high gloss and low oil absorption |
| abstract | The invention discloses a production method of titanium dioxide with high gloss and low oil absorption, and the titanium dioxide aluminum coating comprises the following steps: 1) adjusting the pH value of the titanium dioxide slurry to 3-6 by adopting an acidic aluminum salt solution; 2) adding a metaaluminate solution and an acidic aluminum salt solution into the titanium dioxide slurry in a concurrent flow manner, and controlling the pH value of the slurry to be 3-6; 3) adjusting the pH value of the slurry obtained in the step 2) to 9-11 by using alkali liquor; 4) adding acid liquor and metaaluminate solution into the slurry obtained in the step 3) in a concurrent flow manner, and controlling the pH value of the slurry to be 9-11; 5) adjusting the pH value of the slurry obtained in the step 4) to 6-8 by using acid liquor. The invention can reduce the oil absorption of the product and ensure the product gloss to be unchanged by improving the aluminum-coated process of the titanium dioxide, and can save a certain amount of acid or alkali. |
