Ceramic ink for domestic porcelain and production process thereof

The invention discloses ceramic ink for domestic porcelain and a production process thereof, and belongs to the technical field of ceramic ink preparation, the ceramic ink comprises the following raw materials by mass: 15-20% of ceramic powder, 5-8% of a purification filler, 1-3% of a dispersant, 0.1-0.5% of a wetting agent, 1% of a thickener, and the balance deionized water; the preparation method comprises the following steps: mixing ceramic powder, a dispersing agent, a wetting agent and deionized water, putting the mixture into a grinding tank, grinding with a first zirconium oxide ball until D50 is 1.9-2.1 mu m, adding a purifying filler and a thickening agent, grinding with a second zirconium oxide ball until D50 is 0.5-0.7 mu m and D99 is less than or equal to 1.3 mu m, and finally filtering with a 2 mu m filter element. The self-made purification filler and the thickening agent are introduced into the ceramic membrane, so that the overall stability of the ceramic ink is improved, and meanwhile, the ce
