A large-scale ceramic decorative thin plate and its formulation process

Abstract

The invention provides a large-size ceramic decorative sheet and a formula process.The large-size ceramic decorative sheet comprises a blank layer and a glaze layer.The blank layer comprises a front side and an adhesive side, the front side is a plane, and the adhesive side is a concave-convex side with grooves.The specification of the blank layer is at least 900 mm*1800 mm, and the thickness of the blank layer is 5.5 mm.The glaze layer comprises a glaze bottom layer, a pattern layer and a glaze surface layer, the front side of the blank layer is evenly covered with the glaze bottom layer, the pattern layer is printed on the upper side of the glaze bottom layer, the pattern layer and the glaze bottom layer are covered with the glaze surface layer, and the thickness of the glaze layer is at least 0.3 mm.Formulas include a blank layer formula, a glaze bottom layer formula and a glaze surface layer formula.Pressure of dry pressing in the technological process is 240 MPa, drying temperature is 120-286 DEG C, the drying period is 62 min, upper temperate of firing temperature is 1196 DEG C, lower temperature of firing temperature is 1193 DEG C, and the sintering period is 73 min.

Description

technical field [0001] The invention relates to a ceramic plate, in particular to a large-scale ceramic decorative thin plate and a formula process, belonging to the technical field of the ceramic industry. Background technique [0002] Architectural ceramics are already one of the important building decoration materials that are widely known to everyone. In the family of architectural ceramics, there are many varieties of designs and colors. It is not an exaggeration to describe them as exquisite. After a long history of development, architectural ceramics have introduced many modern technologies, and their quality, specifications and colors have made considerable progress, but the specifications have been restricted by technology and have not made much progress. Due to the constraints of the specifications, there are too many joints on the decorated wall, which cannot give people a sense of integrity as much as possible. Contents of the invention [0003] In order to so...
