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.
