Ceramic brick with super-flat glaze without glaze defect and preparation process of ceramic brick

Abstract

The invention discloses a ceramic brick with a super-flat glaze without glaze defects and a preparation process of the ceramic brick. The ceramic brick comprises a blank body, a bottom glaze layer, a pattern layer, an insulating layer and a transparent glaze layer from bottom to top in sequence, wherein the insulating layer is made of a printing paste with an aqueous tackifying resin in a silk-screen printing manner; and the viscosity of the printing paste is 2000-3000MPa.S. The ceramic brick with the super-flat glaze without glaze defects, which is disclosed by the invention, is high in glaze flatness and clear and fine in glaze pattern, and glaze defects such as glaze pouring orange peel, pinholes and concave glazes are effectively solved.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a ceramic brick with an ultra-flat glazed surface and no glazed defects and a preparation process thereof. Background technique [0002] At present, in the production process of dark ceramic tile products, its color often limits its production. Since the color of the existing inkjet ink cannot meet the inkjet production, the existing inkjet and screen printing technology is usually combined to produce Decorate the pattern on the brick surface, but due to the large amount of oily ink or flower glaze on the brick surface, when the glaze is poured, the oily ink or flower glaze and the water-based glaze slurry often form a phenomenon that oil and water repel each other , resulting in defects such as orange peel, pinholes, and concave glazes on the glazed surface of the tiles. The flatness of the glazed surface is low, and it leads to a serious reduction in the coloring...

[0002] At present, in the production process of dark ceramic tile products, its color often limits its production. Since the color of the existing inkjet ink cannot meet the inkjet production, the existing inkjet and screen printing technology is usually combined to produce Decorate the pattern on the brick surface, but due to the large amount of oily ink or flower glaze on the brick surface, when the glaze is poured, the oily ink or flower glaze and the water-based glaze slurry often form a phenomenon that oil and water repel each other , resulting in defects such as orange peel, pinholes and concave glazes on the glazed surface of the tiles, the flatness of the glazed surface is low, and it leads to a serious reduction in the color effect, low definition and large color difference of the glazed pattern of the dark ceramic tiles
