Preparation method of ceramic tile with matte deep carving effect and ceramic tile

Abstract

The invention provides a preparation method of a ceramic tile with a matte deep carving effect and the ceramic tile. The preparation method of the ceramic tile comprises the following steps: pressinga green body and drying; spraying water to the green body and applying ground coat; the temperature of the green body is kept at 40-45 DEG C, digital mold ink is printed, the ink amount of the digitalmold ink is 15-78 g / m<2>, and the digital mold ink is matte oily ceramic ink; drying, and spraying surface glaze in a reciprocating glaze spraying manner by adopting a high-pressure glaze spraying device, the specific gravity of the surface glaze being 1.5-1.52 g / cm<3>, and the glazing amount being 800-1000g / m<2>; patterns are printed in an ink-jet mode, and then digital matte protective glaze ink and digital bright protective glaze ink are printed; drying and sintering at high temperature; and lightly polishing and edging to obtain the ceramic tile. By means of the method, deeper, finer andmore vivid lines can be formed on the ceramic tile, the carving depth is adjustable by 0.1-5 mm, the method is more intelligent and convenient, and the obtained ceramic tile is attractive, natural andvivid.

Description

Technical field[0001]The invention relates to the technical field of ceramic tile preparation, in particular to a method for preparing a ceramic tile with a matt deep engraving effect and the ceramic tile.Background technique[0002]The application of ceramic inkjet printing technology in the manufacture of ceramic tiles has been developed for many years. The technology has been fully mature, and more than 95% of architectural ceramics companies are using it. However, the technology still stays in the application of color inks, and is compatible with stone, wood, etc. The contrast of surface effects is still not realistic enough.[0003]At present, in order to improve the fidelity and beauty of the surface effect of ceramic tiles, some ceramic tiles with concave and convex three-dimensional effects are usually manufactured. The manufacturing methods of such ceramic tiles are mainly as follows:[0004]1. Use a concave-convex mold to press the required mold effect blank, and then use the co...

AI Technical Summary

Problems solved by technology

[0004] 1. Use a concave-convex mold to press the required mold effect green body, and then use a conventional ceramic preparation method to fire it, but this method requires a variety of mold effects, and it is difficult to overlap the mold effect and pattern texture, which is not realistic enough, and the mold After a period of use, the difference in effect becomes larger

[0005] 2. Use dry granules combined with glue to prepare dry granule slurry, and then apply it to the body or glaze surface to form a concave-convex effect. This method is costly, and the effect is uncontrollable, and it is difficult to overlap with the pattern

For example, the invention CN109485460A discloses a method for preparing ceramic tiles with a three-dimensional pattern texture. The method prints a glue ink layer on the surface of the green body, and then uses dry particles to prepare ceramic tiles. However, since the surface of the green body is porous, the ceramic glue It is easy to quickly penetrate into the body, lose the bonding effect of glue, and it is difficult to ensure that the dry particles can be bonded to the surface of the body and not be sucked away by the fan

For example, the invention CN107417304A discloses a preparation process of a dry brick with a strong three-dimensional effect on the brick surface. The method uses dry granular slurry to be applied to the surface of the green body to prepare a dry brick with a three-dimensional effect. This method is a traditional process, and the three-dimensional effect is difficult. coincide with the pattern effect

[0006] 3. Using sinking ink or sinking ink combined with bright ink to prepare ceramic tiles with concave texture on the flat body, but the ceramic tiles prepared by this method can only show the texture effect of fine lines, the sinking depth is very shallow, and the three-dimensional effect is not strong enough. And vanadium and other substances contained in the sinking ink will affect the color development performance of the color ink, and the ceramic tiles are not beautiful and natural enough.

[0007] It can be seen that the three-dimensional effect of the ceramic tiles obtained by the current manufacturing method is not strong enough, the effect is uncontrollable, and the ceramic tiles are not beautiful and natural enough, which affects the promotion and application of this type of ceramic tiles
