Dry granular glaze glue, dry granular glaze, dry granular glazed tile and preparation method thereof

Abstract

The invention discloses dry granular glaze glue, a dry granular glaze, a dry granular glazed tile and a preparation method thereof. The emphasis is to optimize the composition of the dry granular glaze glue, the composition of the dry granular glaze and the surface tension of the dry granular glaze glue, so that the prepared dry granular glaze glue has preferable suspension property, dispersibility and caking property, and then the prepared dry granular glaze has the characteristics of no sedimentation, no agglomeration, dispersion uniformity, high bonding force and the like; moreover, the drygranular glaze is high in adaptability with ink-jet printing ink, and the dry granular glaze has the advantages of no repulsion, short dry time, high air permeability and the like; a ceramic tile prepared from the dry granular glaze is uniform in surface dry granular distribution and dispersion and warm, fine and smooth in finger touch, dry granular flicker shines under lamplight irradiation, andthe ceramic has a unique decoration effect; the surface of the brick product has the defects of no leakage dry granule, no pinhole, glaze bubble, glaze explosion and the like, decorative patterns areclear, well-bedded and pure in color development, particularly, the dry granular distribution and dispersion on the surface of a dark color printing product is uniform, the color development is colorful, and the product is high in pollution resistance, hardness and abrasive resistance.

Description

Technical field: [0001] The invention relates to the technical field of ceramic glaze preparation, in particular to a dry glaze glue, a dry glaze, a dry glazed tile and a preparation method thereof. Background technique: [0002] At present, with the application of inkjet printing technology in the production of ceramic tiles, the decoration technology on the surface of ceramic wall and floor tiles has changed with each passing day. Many manufacturers of ceramic wall and floor tiles are favored, but it also brings serious disadvantages of homogeneity, which makes the products lose competitiveness. Therefore, some large ceramic tile manufacturers with strong technical research and development capabilities want to break the homogeneity of the inkjet era. To solve the dilemma, apply a layer of dry glaze on the surface of ordinary surface printed and decorated products. After high-temperature calcination, the dry glaze on the surface of these products will sparkle under the ligh...

AI Technical Summary

Problems solved by technology

[0003] However, when applying dry glaze, ordinary glue will cause:

[0004] The dry particle precipitation is difficult to apply glaze, and it is easy to agglomerate, which makes the dry particle distribution on the surface of the product uneven and affects the overall decorative effect;

[0005] It is easy to be sucked away by the fan in the kiln, resulting in the lack of dry grain defects;

[0006] In the production of dark printed products, where dark patterns are prone to appear, because the inkjet ink is not dry for a while, the dry glaze is not compatible with the ink, so the dry glaze cannot be applied;

[0007] Or due to the poor air permeability of the glue, too strong sealing, and poor gas emission during high-temperature firing, defects such as pinholes, air bubbles, or glaze explosions are prone to occur;

[0008] Or because the drying time is too long, the wetting ability of the glue and the pattern is too large, causing the pattern to be blurred and without layers;

[0009] Or because there are too many high-temperature residues in the glue, which affects the hair color, the color is not pure, etc.
