A ceramic rock plate with a 3D digital engraving mold surface effect is prepared by the preparation method.

The preparation method of the ceramic rock plate can prepare rock plates with different sizes, especially large sizes which are difficult to prepare in the prior art.

The pattern of the ceramic rock face can be realized by controlling the ink-jet image according to different requirements, so that a template does not need to be prepared.

The process of ball milling into slurry is to pulverize the raw materials and control the particle size of the particles, so that the green brick provides good conditions for subsequent manufacture.

The slurry is formed into powder, and powder spraying can be realized through powder forming equipment, namely a spray tower.

The ground glaze can adopt glaze materials used in the prior art.

The ink for ink-jet printing adopts an oily suspending agent and a dispergator, so that the ink can be dispersed when being impacted, but can still keep a continuous state.

The method is characterized in that the digital mould glaze is applied, namely the glaze is applied, 8 groups of spray gun groups are flatly arranged, each group of spray gun groups is provided with 8-12 spray guns, the diameter of each spray gun is preferably 0.36mm, and the spraying pressure is 15-18bar, so that an effective and extremely large impact force is formed compared with a spray drawing surface, and under the condition that the materials of the spray drawing surface and the glaze have the characteristics, the method can realize strong layering and strong stereoscopic impression of the rock plate and imitate the ceramic rock plate manufactured by a 3D digital carving mould.

The invention relates to a large-plate super white material.

The ceramic rock plate solves the production problem of large-size rock plates, digitalizes the die, and avoids the problem of poor forming effect of a slightly larger die surface.

The surface texture of the produced ceramic rock plate is a physical concave-convex structure, and is not a concave-convex structure for decorating a shallow surface layer.

The depth, the width and the detail gradation of the surface texture concave-convex of the ceramic rock plate are perfectly presented, and the texture can be finely presented to be 0.01mm fine texture without distortion and passivation.

The direction of the arrows in fig. 3 refers to the direction of the ink or glaze: the downward arrow indicates that the cover glaze 5 of the digital mould moves downwards to form concave force; the upward arrow indicates that the ink 4 ejected produces an upward convex force at a high temperature. The convex force and the concave force meet to form the effect of unevenness.

The preparation method is a brand new technology, replaces the traditional film preparation process, and comprises the steps of ball milling raw materials to prepare powder, controlling the particle size of the powder, after cloth is pressed and formed, applying base glaze, spraying a picture, and spraying digital mold cover glaze on the surface of the sprayed picture.

Because the particle size after ball milling is effectively controlled and the arrangement of the particles is standardized, fine pores exist between the blank powder and the powder after high-pressure pressing, and the ground glaze is applied and the structure of the ground glaze is smooth; and then, ink-jet pattern spraying is carried out on the ground glaze to form a pattern spraying surface, and the ground glaze provides a good and flat bottom for the pattern spraying surface, so that the pattern of the pattern spraying surface can be more completely embodied.

Then, at high temperature, the overglaze adopts a spraying mode of 15-18bar, the impact on the spraying drawing surface is strong, and the particles of the overglaze are downwards impacted in a concave shape due to the spraying mode of a nozzle with the diameter of 0.30-0.36 mm; the molecules on the spray drawing surface form a convex upward movement under high temperature.

Furthermore, the ink of the sprayed surface contains an oily suspending agent and a debonding agent, and in the above state, the convex part impacts the concave position of the overglaze, but the ink of the sprayed surface has a structure that the ink does not completely stay in the concave position, and part of the ink overflows and diffuses, so that the ink and the overglaze are overlapped and crossed.

Further, since the diameter of the spray from the nozzle is small, the pattern on the spray surface is difficult to be destroyed even under strong impact force, and the great destruction capability of the nozzle is only a local tiny range.

Furthermore, because the pressed blank body has pores, the ground coat, the spray drawing surface and the overglaze can downwards penetrate in the high-temperature firing process, thereby further realizing the hierarchical diversification of the ceramic rock plate.
