Emulsifiable paste stamp-pad ink for reticular lamina printing decoration of ceramic brick for wall and ground

Abstract

The invention relates to cream stamp-pad ink for printing patterns on mesh plates of ceramic tiles, which is a mixture consisting of the following compositions by weight: 20 to 35 percent of ethylene glycol, 20 to 35 percent of glycerol, 30 to 45 percent of sorbitol, 1 to 7 percent of cellulose, 2 to 8 percent of a macromolecule polymer, and 0.2 to 1.0 percent of an exciting agent. The appearanceof the cream stamp-pad ink is of milk white cream shape without off flavor; the viscosity is between 4,800 and 5,200 MPa.S; the density at 20 DEG C is between 1.040 and 1.050; the pH value is between6 and 8; the water-soluble residue with 360 meshes is less than or equal to 0.2 percent; and the freezing point is 10 DEG C below zero. The burnt ash content of products is low without residues; the stability and the suspending power are good without layering; the proportion and the viscosity are adjustable; pattern-printing glaze slurry prepared from the cream stamp-pad ink can be used normally on-line after storage without the appearances of color differences and pinholes; and the cream stamp-pad ink is applicable to the pattern-printing requirements for various high-grade, middle grade andlow grade ceramic tiles produced by different ceramic building factories. The pattern-printing glaze slurry prepared from the cream has certain fluidity, the performances of moisture, lubrication, mesh brightening and the like, and increases the adhesive force of the pattern-printing glaze slurry on blanks; besides, the surface of a sintered tile finished product is smooth and has no defects of unevenness, pinholes and the like, and the patterns are clear and bright.

Description

technical field [0001] The invention belongs to the category of cream printing oil in the ceramic industry, in particular to a cream printing oil for screen printing of ceramic wall and floor tiles. This cream printing ink has strong applicability and can fully meet the different needs of printing on interior wall tiles and floor tiles of various specifications; it can be applied to high-gloss tiles, calendered tiles, crystal tiles, antique tiles, interior wall tiles, etc. Background technique [0002] In the prior art, the quality of cream printing oil products for screen printing of ceramic wall and floor tiles is not satisfactory, or its specific gravity and density are insufficient, and it is easy to precipitate and layer when placed, resulting in color difference; or poor lubricity and screen penetration; Or the bonding force of the glaze slurry to the green body is weak, and the surface of the ceramic wall and floor tiles after firing is poor in cleanliness, with defec...
