Embodiment 1
[0032] The preparation method of a kind of compound package type cerium sulfide red pigment of present embodiment, its steps are as follows:
[0033] (1) Prepare a hydrolysis raw material solution
[0034] Toner suspension: 0.5g γ-Ce 2 S 3 Toner and 0.05g dispersant cetyltrimethylammonium bromide (CTAB) were added to a mixed solution of 25ml absolute ethanol and 50ml deionized water, aged for 24h under magnetic stirring, and centrifuged once to remove excess dispersion. Add the pretreated colorant to 75ml of absolute ethanol again, magnetically stir and sonicate to carry out secondary dispersion, stir and disperse evenly, add 1mol / L sodium hydroxide to adjust the pH of the solution Value is 12, and prepared toner suspension;
[0035] Zirconium source solution: use 1ml zirconium butoxide as the zirconium source solution;
[0036] Hydrolysis aid: Dissolve 0.55g of anhydrous sodium acetate in 5ml of deionized water to prepare a hydrolysis aid;
[0037] (2) Prepare a packaged...
