| titleOfInvention | A kind of preparation method of special titanium dioxide for inner printing ink |
| abstract | The invention belongs to the technical field of titanium dioxide preparation, and discloses a preparation method of titanium dioxide special for lining ink, comprising: preparing titanium dioxide slurry; The pH value is 6-7; the first batch of silicate solution is added to the slurry, and the temperature of the slurry is raised to 80-90°C; the second batch of silicate solution is added to the slurry; the pH value of the slurry is adjusted temperature to 25-60℃; add NaAlO 2 solution and H 3 PO 4 solution to the slurry at the same time, keep the pH value of the slurry at 4-6; sand the slurry; add aluminum salt solution Add NaOH or dilute acid solution to the slurry to keep the pH value at 4-6; adjust the pH value of the slurry to 6-8 with NaOH solution, and then carry out water washing, drying and steam powder to obtain the finished titanium dioxide. The titanium dioxide prepared by the invention has better covering power, viscosity and formula applicability. |
