Method for producing stain-bleeding porcelain tile

Abstract

The invention relates to a method for producing stain-bleeding porcelain tile. The method comprises the following steps: A) spreading powder in a mold cavity of a lower mold of a stamping mold, obtaining a base substrate having an edge ring by stamping and compacting the upper mold, arranging a boss on a stamping surface of the upper mold, wherein the boss area is less than the material distribution area of the mold cavity of the lower mold, forming a material distribution chamber by encircling the edge ring on the surface of the base substrate, transferring the base substrate for standby; B) drying the base substrate obtained in the step A), uniformly applying batter in the material distribution chamber to form a decorative layer; C) using a digital ink-jet printing machine for printing the surface of the base substrate applied with batter by using a water-soluble stain-bleeding ink according to the designed stain-bleeding patterns; D) drying the base substrate obtained in the step C), placing the base substrate in a kiln for sintering; and E) polishing and grinding the sintered tiles. The stain-bleeding porcelain tile has the advantages that slurry layer thickness is increased, wear resistance and pollution tolerance are good, and the three-dimensional decorative effect is good.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a method for preparing porcelain tiles with bleeding patterns. Background technique [0002] At present, the "bleeding" polishing technology is generally used in the production of bleed porcelain tiles. With the continuous improvement of technology, water-soluble bleed ink has appeared on the market to penetrate into the inside of the surface paste layer and react with it, and the interaction between it and the paste. Combining, after high-temperature firing, the color is formed to form three-dimensional coloring, which increases the three-dimensional effect of the printed pattern. After polishing, it solves the problems of single color, not bright enough color, and not rich enough color.

[0002] At present, the "bleeding" polishing technology is generally used in the production of bleed porcelain tiles. With the continuous improvement of technology, water-soluble bleed ink has appeared on the market to penetrate into the inside of the surface paste layer and react with it. Combined, after high-temperature firing, the color is formed to form a three-dimensional coloring, which increases the three-dimensional effect of the printed pattern. After polishing, it solves the problems of single color, not bright enough color, and not rich enough color of the bleed porcelain tile.

[0003] However, since the four sides of the green body are usually a single plane, when decorating the green body with batter paste, it is affected by the fluidity of the batter paste, so that the thickness of the dough paste application is less than 3 mm, which limits the application of the dough paste. weight, and the dispensing of batter is not only for decoration and beauty. By distributing batter with different components, we can prepare bleed porcelain tiles with different performances, but the amount of bleed is limited, resulting in bleed porcelain tiles Therefore, the performance is limited. For example, if you want the bleed porcelain tile to have high wear resistance and high stain resistance, and the water-soluble bleed ink has a good penetration effect, you need to ensure a sufficient amount of batter. Therefore, at present, this problem need a good solution
