[0002] Natural stone is mined from natural rock and is a non-renewable resource. It mainly includes granite and marble. Each piece has a unique texture with clear and distinct textures and layers.

[0003] In modern times, the consumption of stone is huge, which has led to the development of ceramic tiles to replace natural stone, avoiding excessive mining. The texture and structure of ceramic tiles have been imitating natural stone, while also solving the hardness and production problems that natural stone lacks.

[0004] However, how to develop better tiles with a sense of layering, texture, and more like natural stone that are different from the existing technology is one of the directions that technical personnel in this field should develop. Summary of the invention

[0005] The invention discloses a glazed tile with the performance of replicating the effect of natural stone and a preparation process thereof. The glazed tile has the hardness of ceramic tiles and also has clear textures, distinct layering and a delicate and moist surface like natural stone.

DETAILED DESCRIPTION

[0025] The invention discloses a glazed tile with the performance of replicating the effect of natural stone and a preparation process thereof. The glazed tile has the hardness of ceramic tiles and also has clear textures, distinct layering and a delicate and moist surface like natural stone.

[0026] The present invention provides a glazed tile having the performance of replicating the effect of natural stone, comprising the following preparation steps:

[0027] A. Spraying modified ball clay onto the pressed green body;

[0028] B. Glaze;

[0029] C. Spray ink patterns and carved ink patterns on the surface;

[0030] D. Applying duplicate glaze;

[0031] E. Firing;

[0032] The amount of the modified ball clay, the glaze and the replica glaze is based on a standard plate of 450mm*450mm, and the usage amounts are: 20 grams, 85 grams and 60 grams respectively.

[0033] Preferably, the modified ball clay in step A comprises the following raw materials calculated in parts by weight: 60-65 parts by weight of ball clay powder, 2-5 parts by weight of calcined alumina, 5 parts by weight of ultra-white kaolin, 5 parts by weight of ultra-white quartz, 18-22 parts by weight of albite, 2 parts by weight of calcined talc, and 3 parts by weight of zirconium silicate.

[0034] Preferably, the glaze of step B comprises the following raw materials calculated in parts by weight: 6-10 parts by weight of calcined alumina, 12-15 parts by weight of ultra-white kaolin, 12-15 parts by weight of ultra-white quartz, 55-60 parts by weight of albite, 4 parts by weight of calcined talc, and 8 parts by weight of zirconium silicate.

[0035] Preferably, the replica glaze of step D comprises the following raw materials calculated in parts by weight: 5 parts by weight of burnt talc, 6-10 parts by weight of dolomite, 4 parts by weight of calcined kaolin, 15 parts by weight of barium carbonate, 10 parts by weight of kaolin, 23-25 ​​parts by weight of potassium feldspar, 34 parts by weight of frit, and 3-5 parts by weight of zinc oxide.

[0036] Preferably, the inkjet pattern and the finely carved ink pattern are independent in position, non-interlaced and non-overlapping.

[0037] Generally speaking, the finely carved ink pattern is preferably arranged on the outer layer of the lines of the inkjet pattern to better highlight the effect.

[0038] Preferably, the replica glaze in step D is a low-temperature glaze.

[0039] Preferably, the fine carving ink in step C is a low-temperature and high-brightness fine carving ink.

[0040] Preferably, the particle size of the modified ball clay is 2-5 μm.

[0041] Preferably, the specific gravities of the modified ball clay, the glaze and the replica glaze are 1.2, 1.85 and 1.45 respectively.

[0042] Preferably, after step E, step F of brush polishing is also included.

[0043] The present invention combines the low-temperature effects of fine carving ink and replica glaze, and cooperates with surface glaze and inkjet patterns to restore the uneven effect of the natural stone surface. The product has the advantages of clear texture, distinct layering, delicate and warm glaze without being thick, high wear resistance, anti-slip and anti-fouling.

[0044] The glazed tiles also have what natural stones lack: a three-dimensional brick surface and extremely high glossiness, with a soft and warm texture like solidified fat.

[0045] This glazed tile is a matte glazed tile with a glossiness of 30°. The 3D effect achieved by common tiles of the same type is a 3D effect formed by following the concave and convex texture of the surface.

[0046] This glazed tile uses fine-carving ink and replica glaze to outline the texture details, which not only produces a concave and convex 3D effect, but also matches the concave and convex texture to the product pattern, so that a brick can have both glossy and matte concave and convex effects.

[0047] During the preparation process, the modified ball clay covers the holes on the body to prevent pinhole rashes from appearing on the glaze surface, and the surface glaze covers and decorates the body.

[0048] The glaze has a high specific gravity and is used in large quantities. During the firing process, it will fall on the body and achieve a melting effect first;

[0049] Next, the fine carving ink is a low-temperature ink, which can easily push away the glaze, that is, the effect of pushing away the replica glaze is better. The fine carving ink and the inkjet pattern do not overlap, the two are separate. The fine carving ink is generally set at the line, which can push away the glaze, making the line appear concave and convex;

[0050] Furthermore, the replica glaze is a low-temperature glaze, which contains more low-temperature solvents such as calcium and magnesium. The replica glaze has a low specific gravity and strong fluidity. The melting process is later and the amount is small, so the glaze layer is thin, making it easier to remove. The melting process is faster and better, and the glazed tiles formed are not thick and more like natural textures.

[0051] Therefore, through the different melting times and states during the firing process, the glazed tiles achieved have more natural texture, concave and convex texture and high-definition texture.

[0052] This is a double-superposition mechanism, which undergoes complex changes during the firing process, so it has certain uncontrollable natural changes, making the glazed tiles appear more natural.

[0053] The biggest highlight of the present invention is that the undulating texture can be completely matched to the product pattern, and the same brick can have both glossy and matte effects.
