Description
Technical Field
The invention relates to a ceramic processing technology, in particular to a preparation method of a terrazzo-like ceramic plate with concave-convex texture and a ceramic plate thereof.
Background
With the development of economy and the improvement of the living standard of people, the building decoration industry receives more and more attention and occupies a main part in home decoration. The ceramic product at the present stage is formed by pressing through a large-tonnage press and then firing at a high temperature, and has better physical and chemical properties compared with artificial stones, natural stones and the like. The terrazzo is superior in color and three-dimensional texture without doubt due to its natural characteristics in that the surface color and texture are natural, but as it is continuously mined, natural mineral resources are increasingly scarce. Therefore, the ceramic product with the simulated terrazzo color and three-dimensional texture effect replaces the traditional terrazzo, and is one of the current product directions of ceramic production enterprises.
In the existing preparation process of the terrazzo, the terrazzo-like ceramic product with the three-dimensional texture effect is mostly manufactured by adding physical particles or prefabricating a die with a certain three-dimensional shape. For example, the ceramic ink-jet printing technology is used for spraying and printing a ceramic tile product with granular and flaky patterns imitating terrazzo on the surface of the ceramic to obtain granular and flaky terrazzo imitating textures, but because the shapes of the ink-jet pattern elements are fixed and unchanged, the grains at each position of each tile product cannot be different, the tile product looks unnatural, and the effect of surface printing is only the substance of the ceramic tile product, so that the ceramic tile product has certain limitations. For another example, CN112192739A is a process for manufacturing terrazzo-like ceramic panels, which is to design a plurality of sets of ceramic powder pressing tablet sub-modules, combine with a front hopper and a receiving belt to form an integrated material distribution system for installation and use, so as to obtain tablet terrazzo-like textures.
In addition, the ceramic plate which spontaneously forms the terrazzo-like effect with concave-convex texture has deep texture, deep texture of terrazzo, thin protective glaze, insufficient protectiveness and antifouling property, and external stains are gathered to influence attractiveness as time goes on.
Therefore, there is a need to develop a process for preparing a ceramic plate capable of spontaneously forming a terrazzo-like effect with concave-convex texture on the surface of a brick body, wherein the concave-convex texture obtained by the preparation process has spontaneity, diversity and flexibility, is very natural and close to natural texture, and can overcome the technical problems of deep texture, insufficient protection and insufficient antifouling property.
