A kind of finely carved ceramic tile and its production process

Abstract

The invention relates to the field of ceramic brick production, and provides a finely carved ceramic brick and a production process thereof, which are used to provide a ceramic brick with good hand feeling. A finely carved ceramic tile provided by the present invention includes a surface glaze and a green body, the surface glaze includes a bottom glaze, an ink layer and a covering glaze, and the covering glaze includes 20 to 30 parts by mass of albite, 10 to 15 parts by mass of kaolin parts by mass, 5-10 parts by mass of dolomite, 1-5 parts by mass of aluminum oxide, 3-10 parts by mass of zinc oxide, 5-10 parts by mass of calcined talc, and 35-50 parts by mass of frit. Optimizing the raw materials of the covering glaze can produce ceramic tiles with better hand feeling. At the same time, the surface of the ceramic tiles is matte, and the ink and glaze are co-fired to form a characteristic texture similar to natural materials.

Description

technical field [0001] The invention relates to the field of ceramic brick production, in particular to a finely carved ceramic brick and a production process thereof. Background technique [0002] The rapid development of inkjet technology has brought earth-shaking changes to the pattern decoration of ceramic products. As a result, many ceramic manufacturers have used various functional glazes and functional inks to increase the surface decoration effect of ceramic tiles. Among them, decorative ceramic tiles with cracks and sinking effects are popular among consumers because of their marble-like texture. But at present, for glazed tiles, the edges of the cracks formed are relatively smooth, and the sunken parts are easy to melt and flatten, resulting in relatively rigid transition changes of the crack lines, difficult to control the thickness and transition of the crack lines, and the crack effect is not delicate enough. It is difficult to control the effect of the brick s...

Problems solved by technology

But at present, for glazed tiles, the edges of the cracks formed are relatively smooth, and the sunken parts are easy to melt and flatten, resulting in relatively rigid transition changes of crack lines, difficult to control the thickness and transition of crack lines, and the crack effect is not delicate enough. It is difficult to control the effect of the brick surface during the process, and it is easy to throw away part of the pattern, so that the crack effect of the glazed brick is not good, it is difficult to control and it is not conducive to large-scale promotion

[0003] At the same time, the existing technology has high requirements on the polishing process after firing, and the process is difficult
