High-simulation digital mold ceramic tile and preparation method thereof

Abstract

The invention discloses a high-simulation digital mold ceramic tile and a preparation method thereof, and relates to the technical field of architectural ceramic. Before color ink is applied, a ground glaze layer, a mold ink layer, a cover glaze layer and a color glaze layer are sequentially arranged on a ceramic tile green body, and by controlling main glaze components of the ground glaze layer, the mold ink layer and the cover glaze layer to be kept consistent, the concave part is enabled to be consistent with the peripheral plane or the convex part in glaze component after the ceramic tile is fired, so that the same influence is generated on the color development of color ink at the concave part and the peripheral plane or the convex part and the gloss of the upper protective glaze layer, the uniform and consistent color development and gloss of patterns at the concave part and the peripheral plane or the convex part are ensured, the pattern color and luster transition is natural, the surface texture of the digital mold ceramic tile is remarkably improved, and a ceramic tile product which is closer to the surface effect of real stone, wood, cloth, leather and other materials is obtained.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a high-simulation digital mold ceramic brick and a preparation method thereof. Background technique [0002] In the past two years, with the popularity of large slabs and slate products, and the increase in the proportion of ceramic products used on walls, desktops, and counters, consumers have put forward higher demands for architectural ceramic products, and pay more attention to the surface texture of ceramic tiles. , touch, more emphasis on its detailed texture. In particular, for ceramic tile products with concave-convex texture effects on the surface of imitation stone, wood, cloth, leather, etc., it is required not only to be more realistic in pattern, but also to achieve the real stone, wood, cloth, leather, etc. in terms of detailed texture. Look and feel, presenting a highly simulated effect. [0003] Natural stone, wood, cloth, leather and other products ha...

Problems solved by technology

This method belongs to the traditional process, and has the following disadvantages: (1) A physical mold needs to be prepared for each concave-convex texture, and the flexibility is not good; (2) The mold will exert pressure on the adobe. It is difficult to use this method to achieve surface concave-convex texture for slab and rock slab products; (3) the mold cannot suppress very fine texture, which may easily lead to loss of details; (4) the concave-convex texture on the surface of the brick will change with the physical wear of the mold, and it is difficult to guarantee batch stability

This method has the following disadvantages: (1) In order to ensure the normal flow of dry particles, the size of dry particles is generally large, so it is impossible to obtain very narrow raised lines; (2) after firing, the glaze composition and There is a big difference in the composition of the glaze on the plane, which leads to a big change in the color of the color ink and the gloss of the glaze on the raised part and the surrounding plane. Imitation stone, wood, cloth, leather and other surface effects

This method has the following disadvantages: (1) The concave line texture formed by this method is completely formed by the melting and volatilization of low-temperature substances at high temperature, so the corners of the formed texture are easy to collapse and are not three-dimensional and sharp; (2) due to the subsidence / The etchant used in Jingdiao ink is mostly vanadium compounds. When the content of the etchant is high, there will often be yellow residues on the lines after firing, which will affect the color of the pattern texture; There is a large difference. After firing, the hair color and gloss of the lines are difficult to keep consistent with the surrounding areas. The color and gloss transition of the pattern texture is blunt, and the texture decreases. It is impossible to achieve realistic imitation of stone, wood, cloth, leather and other surface effects.

This method has the following disadvantages: (1) limited by the current technical level, it is difficult for solid particles in the mold ink to accumulate thick bumps; (2) due to the oil-water repulsion effect, it is difficult to accumulate commonly used Water-based protective glaze slurry, the use conditions are limited; (3) It is difficult to keep the same composition between the raised part and the surrounding area, resulting in differences in the color and luster of the raised part and the surrounding pattern, and it is impossible to achieve realistic imitation of stone, wood, cloth, leather and other surfaces Effect

This method has the following points to be improved: (1) When a wider line texture is required, if the performance of the oil-based effect ink is not properly matched, glaze beads will often appear in the groove, which will affect the appearance of the line; (2) Where the mold ink is sprayed, The sunken effect is formed because the glaze on the upper layer is pushed away, resulting in a significant difference in the composition of the glaze here and the surrounding area, and it is difficult to keep the pattern color and gloss after firing consistent with the surrounding area, resulting in the pattern color and gloss of the concave and convex parts in the same area. There is a large difference in the degree of accuracy, the texture is reduced, and it is impossible to achieve realistic imitation stone, wood, cloth, leather and other surface effects

[0009] In summary, when the existing ceramic tiles realize the three-dimensional concave-convex texture effect, it is difficult for the surface depressions and protrusions to transition naturally with the surrounding areas, and the pattern color and gloss after firing cannot be consistent with the surrounding areas. Based on the existing technology, it is still difficult to obtain high-simulation digital mold ceramic tiles
