Preparation method of terrazzo-imitated ceramic plate with concave-convex texture and ceramic plate

Abstract

The invention discloses a preparation method of a terrazzo-imitated ceramic plate with a concave-convex texture and a ceramic plate thereof, and the preparation method comprises the following steps: forming a green body, drying, spraying digital overglaze ink, spraying digital overglaze, drying, decorating patterns, spraying digital protective glaze, drying, spraying antifouling dry grain protective glaze, firing, polishing, detecting and warehousing. The terrazzo-imitated ceramic plate with the concave-convex texture is obtained. According to the preparation process, the terrazzo imitation effect with the concave-convex texture can be spontaneously formed on the surface of the brick body, and the obtained concave-convex texture has spontaneity, diversity and flexibility, is very natural and is close to natural texture. In addition, the terrazzo is deep in texture, thin in digital protection glaze, insufficient in protectiveness and insufficient in antifouling property; by spraying the antifouling dry particle protective glaze, on one hand, the antifouling property is improved, and on the other hand, the decorative effects of wear resistance, hardness, color development, antifouling property, transparency and the like can be improved.

Description

technical field [0001] The invention relates to a ceramic processing technology, in particular to a method for preparing a terrazzo imitation ceramic plate with concave-convex texture and the ceramic plate. Background technique [0002] With the development of the economy and the improvement of people's living standards, more and more attention has been paid to the architectural decoration industry, which occupies a major part in home decoration. Ceramic products at the present stage are made after being pressed by a large-tonnage press and fired at a high temperature. Compared with artificial stone and natural stone, they have better physical and chemical properties. Terrazzo undoubtedly has advantages in terms of color and three-dimensional texture because of its natural characteristics in surface color and texture. However, as it is continuously mined, natural mineral resources are becoming increasingly scarce. Therefore, it is one of the current product directions of ce...

Problems solved by technology

Another example is the Chinese patent CN112192739A, a terrazzo-like porcelain plate manufacturing process, through the design of multiple sets of ceramic powder pressing tablet particle modules, pre-loading hoppers and belts to be combined into an integrated distribution system for installation and use, so as to obtain flakes and granular materials. Imitation of terrazzo texture, but the molding method is still the mold fabric system, the three-dimensional texture depends on the mold shape, the update speed of this new craft is slow, and the pattern cannot be flexibly adjusted according to the demand, so the three-dimensional texture is single, not diverse, and inflexible

[0004] In addition, since the ceramic ceramic plate of the present application spontaneously forms a terrazzo-like effect with a concave-convex texture, its texture is deep, the texture of the terrazzo is deep, the protective glaze is thin, the protection is not enough, the anti-fouling is not enough, and the external stains accumulate over time, Affecting the appearance, the above-mentioned technical problem is still a technical difficulty to be overcome urgently

[0005] Therefore, it is necessary to develop a ceramic ceramic plate preparation process that can spontaneously form a terrazzo-like effect with a concave-convex texture on the surface of the brick body. Natural texture, at the same time, it can overcome the technical problems of deep texture, insufficient protection and insufficient antifouling
