The invention aims to solve another technical problem of providing a method for preparing the ceramic DIY colored drawing pigment.
The ceramic painting is, as its name suggests, directly painted on a porcelain, and the surface texture of the porcelain is different from that of general painting instruments such as paper, drawing board, etc., and the initial appearance of painting on the porcelain with a pigment is not significantly different from that of the general painting instruments, but the porcelain is easily pulverized, dropped, grayed, etc. after being left to stand, and the appearance is deteriorated. In view of the above phenomena, the applicant indicates that most of the color components of the ceramic DIY colored drawing pigments are organic pigments, the organic pigments themselves have poor weather resistance and poor dispersibility in an aqueous system, and the pigments are bright in color but cannot withstand the test of time; on the other hand, the ceramic surface has strong granular feeling, the poor pigment dispersibility can cause uneven pigment coverage, the fine greasy feeling is not strong, the adhesive force of the pigment on the ceramic surface is inconsistent, and the appearance defect on the local part is easy to appear.
Based on the existing ceramic colored drawing pigment and the defects thereof, the special composition is added to improve the defects of the colored drawing pigment and improve the dispersibility and the aging resistance of the colored drawing pigment.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

The sodium bentonite is preferably 50 to 75 mass%, more preferably 60 to 70 mass%, in the additive.
The micronized wax refers to polyethylene wax which has good dispersion effect and anti-sedimentation effect in a system, and can further enable organic pigments to have better dispersibility in the system and enable colored drawing pigments to show stronger stereoscopic impression by matching with sodium bentonite.
