A kind of glazed brick with crackle effect and its preparation process

Abstract

The invention discloses a glazed tile with a crack effect and a preparation technology thereof. The preparation technology comprises the steps: (1) spraying clean water on the surface of a green brickof a ceramic tile and applying high-temperature cover glaze to form a high-temperature cover glaze layer, wherein the high-temperature cover glaze contains silicon dioxide with the weight percentagelarger than 55%, a proportion of a silicon-aluminum ratio is 2.3 to 2.5, and the glazing amount is a 110+ / -2g / 330*660 measurement disk; (2) jet printing decoration ink on the cover glaze layer to forma decoration pattern layer; (3) jet printing bright protection ink on the decoration pattern layer and then jet printing engraving ink, wherein the ink jet amounts are both larger than 30 / m<2>; (4) spraying polish glaze on the surface of the green brick, wherein the polish glaze contains superfine aluminum oxide with the mass percent as 1.5 to 3%, and the glaze spraying amount is a 135+ / -g / 330*660 measurement disk; (5) drying the green brick before the green brick is put into a kiln and performing high-temperature sintering, polishing and edging treatment to obtain the glazed tile with the crack effect. Thickness and transition of the crack lines of the glazed tile prepared by the glazed tile preparation technology disclosed by the invention are easier to regulate, a line effect is more obvious and vivid, and good antifouling performance is further achieved.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a glazed tile with crack effect and a preparation 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 ...

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
