Full-body porcelain tile and preparing method thereof

Abstract

The invention discloses a full-body porcelain tile and a preparing method thereof. The preparing method includes the steps of evenly spreading a porcelain blank base material on a material spreading car belt, forming linear filling pits in a blank body according to the unclosed linear route through a material scrapping cone after pre-rolling forming, and instantaneously supplementing color-matchedporcelain powder through a material supplementing cone connected with the material scrapping cone. After a material scrapping and supplementing line is formed, the porcelain blank body with a coloredline texture on the full body is formed through dry-pressing forming. Ground glaze pouring, ink-jet printing or silk-screen printing for forming the line texture corresponding to the colored line texture on the full body and transparent glaze pouring are conducted on the porcelain blank body. The porcelain blank body is put in a kiln for high-temperature firing and edge grinding and polishing after being dried, so the porcelain tile with the full-body effect is obtained. The distribution of the textile lines of the surface of the prepared full-body porcelain tile is consistent with the distribution of the textile lines in the blank body, and the full-body porcelain tile has the real full-body effect and is good in pattern wear resistance, simple in process and low in cost.

Description

technical field [0001] The invention relates to the technical field of ceramic tile preparation, in particular to a full-body porcelain tile and a preparation method thereof. Background technique [0002] The porcelain tile defined in the national standard is a ceramic tile product with a water absorption rate of less than 0.5%. Because of its high strength, low water absorption rate, good wear resistance and stain resistance, it is widely used and has a broad market space. Porcelain tiles have now become the main product category in the architectural ceramics industry, including polished tiles, glazed tiles, marble tiles and other detailed classifications. In recent years, with the continuous improvement of equipment and technology in the building ceramic industry, while realizing the excellent physical properties of porcelain tile products, special attention has been paid to the play of its decorative effect: it is expected that porcelain tile products can be as close as p...

Problems solved by technology

However, the preparation method of this application has the following deficiencies: (1) the cloth of the color green body layer adopts the common "material accumulation" cloth mode in the industry, that is, various color material powders are scattered from the cloth mouth by gravity after being mixed. On the belt of the cloth car, until the cloth of the colored green body layer is completed, the randomness of the whereabouts of the powder is relatively large

In this way, although the green body layer contains various color materials, its distribution is uncontrollable, and the distribution of the envisioned texture lines cannot be realized, and the subsequent pattern decoration layer does not match the pattern of the colored green body layer, which is not really meaningful. (2) The glaze with a sinking effect applied by screen or inkjet printing matches the lines of the patterned decorative layer, and after firing, it is painted on the surface decorative layer (actually transparent glaze) The "depression" effect corresponding to the pattern decoration layer is formed; this so-called three-dimensional effect only accounts for a small proportion in the thickness direction of the brick, and it is only the "three-dimensional" of the transparent glaze layer, not the "three-dimensional" of the color line texture. Therefore, the overall three-dimensional decoration effect is extremely limited; (3) There are many preparation processes, the process is complicated, and the distribution of colored materials is relatively unreasonable, resulting in higher product costs
