The invention discloses a preparation method of a special titanium dioxide for an oily system. The method comprises the following steps: 1, pulping to prepare a titanium dioxide suspension slurry, adding a dispersant, dispersing, and grinding; 2, diluting the ground titanium dioxide suspension slurry, and filtering; 3, adding a zirconium compound, curing, and depositing; 4, adding an aluminum compound, curing, and depositing; 5, adjusting the pH value, and curing; and 6, washing, drying, and carrying out airflow crushing. The method allows the surface of a titanium dioxide particle to be respectively coated with a zirconium oxide film and an alumina film inside out and a silane coupling agent hydrolysate to be adopted to carry out organic treatment, so the special titanium dioxide has the advantages of substantially-increased weather resistance, lipophilicity and luster, low oil absorption, good dispersity, realization of the hiding capability same to import titanium dioxide, high contrast rate, good temperature resistance, and no ink layer yellowing.
