Ceramic digital protective glaze ink as well as preparation method and application thereof

[0062] In some embodiments, the preparation method includes the steps of:

[0063] Step A: preparing powder;

[0064] Step B: Mix the solvent, hyperdispersant, powder, surfactant and anti-sedimentation agent, and then grind until the fineness is D50<400nm to obtain a slurry;

[0065] Step C: filter the slurry, and pack to obtain the finished ceramic digital protective glaze ink.

[0066] In some embodiments, the step A includes:

[0067] Mix the powder raw materials;

[0068] The mixed powder raw materials are refined.

[0069] In some embodiments, coulter mixer or wet ball mill mixing is used.

[0070] In some embodiments, jet mill or wet sand mill is used to refine the powder raw material, and the refinement treatment requires a particle size D100<15 μm, and further requires a particle size D100<10 μm.

[0071] In some embodiments, in step B, a sand mill is used for grinding.

[0072] In some embodiments, the mill is a horizontal sand mill.

[0073] In some embodiments,

[0089] The digital protective glaze ink is prepared according to the following formula, and the digital protective glaze matte I ink is composed of the following components according to the mass percentage:

[0090] Powder 45%
