Digital mold brick with physical blank mold effect and preparation method thereof
By employing water-based digital glaze, surface glaze, and protective glaze with specific chemical compositions in ceramic mold bricks, the problems of high physical mold costs and poor digital mold effects in existing technologies are solved, achieving a natural and smooth transition effect that matches the texture of the raised and recessed areas with the pattern texture, making it suitable for small-batch flexible production.

Abstract
This invention belongs to the field of architectural ceramics technology and discloses a molded brick that mimics the effect of a physical mold and its preparation method. This molded brick combines the characteristics of both physical molds and digital molds, and from bottom to top comprises a body, a water-based digital glaze layer, a surface glaze layer, a color ink layer, and a protective glaze layer. The water-based digital glaze layer is formed by inkjet printing and is located on the raised parts of the molded brick. The raw material components of the water-based digital glaze include inorganic glaze, water, and additives. The chemical composition of the inorganic glaze, by weight percentage, includes: Al₂O₃ 28-32%, SiO₂ 50-55%, CaO 1-2%, MgO 0.5-2%, K₂O 2-4%, Na₂O 1-3%, ZrO₂ 3-5%, and loss on ignition 1-3%. The specific gravity of the water-based digital glaze is 1.6-1.7 g / cm³. 3 And its viscosity at 25℃ is 100-200 mPa•s.
