[0034] A method for preparing a tile made of pomegranate ruby ​​material comprises the following steps:

[0035] S1. Prepare a transparent material with a transmittance of 0.35-2% and a whiteness of 73-85 degrees;

[0036] S2. Using transparent material as the base material, combined with blank colorant, to prepare long strips - black leaf particles, ruby ​​- rose particles;

[0037] S3. Scan the stone, use the grayscale image, make a concave-convex mold with the same preset stone surface, use the leaf grid to lay out the long strip-black leaf particles, and the rose grid to lay out the ruby-rose particles, and then press the concave-convex mold to obtain a blank;

[0038] S4. The green body is dried and dried, and a digital glue and a glittering mixture are sprayed on the glaze line of the green body to form a glittering effect on the surface of the green body obtained in step S3;

[0039] S5. Spray matte protective glaze on the surface of the body in step S4;

[0040] S6. The green body obtained in step S5 is fired and polished in sequence to obtain tiles made of pomegranate ruby ​​material.

[0041] In some embodiments of the present invention, in step S1, the raw material composition of the permeable material includes the following raw materials in parts by weight:

[0042] 8-20 parts of ultra-white kaolin, 3-8 parts of high plastic mud, 7-20 parts of high-white ball clay, 1-6 parts of high-white bentonite, 1-10 parts of ultra-white quartz sand, 18-30 parts of high-white potassium sand, 12-20 parts of high-white sodium sand, 1-7 parts of bone meal, and 1-5 parts of talc mud.

[0043] It can be understood that in the present application, the raw material composition of the permeable material, for example, includes 8 parts of ultra-white kaolin, 3 parts of high plastic mud, 7 parts of high white ball clay, 1 part of high white bentonite, 1 part of ultra-white quartz sand, 18 parts of high white potassium sand, 12 parts of high white sodium sand, 1 part of bone meal, and 1 part of talcum mud; or includes 20 parts of ultra-white kaolin, 8 parts of high plastic mud, 20 parts of high white ball clay, 6 parts of high white bentonite, 10 parts of ultra-white quartz sand, 30 parts of high white potassium sand, 20 parts of high white sodium sand, 7 parts of bone meal, and 5 parts of talcum mud; or includes 10 parts of ultra-white kaolin, 5 parts of high plastic mud, 12 parts of high white ball clay, 3 parts of high white bentonite, 5 parts of ultra-white quartz sand, 23 parts of high white potassium sand, 16 parts of high white sodium sand, 3 parts of bone meal, and 2 parts of talcum mud.

[0044] The specific preparation method of the transparent material is as follows: according to the weight composition of each raw material of the transparent material, the materials are mixed after being taken, and after ball milling, a transparent material with a transmittance of 0.35-2% and a whiteness of 73-85 degrees is obtained.

[0045] Therefore, the present application mainly provides a transparent material with a transmittance of 0.35-2% and a whiteness of 73-85 degrees as a basic material; the specific selection of the transparent material can be a transparent material with a transmittance of 0.35-0.7% and a whiteness of 73-77 degrees; or a transparent material with a transmittance of 0.7-1.4% and a whiteness of 77-81 degrees; or a transparent material with a transmittance of 1.4-2% and a whiteness of 81-85 degrees; or a transparent material with a transmittance of 0.35-0.7% and a whiteness of 77-81 degrees; or a transparent material with a transmittance of 1.4-2% and a whiteness of 77-81 degrees.

[0046] In some embodiments of the present invention, in step S2, the long black leaf particles are made into black long strip particles by double-roll extrusion, and the length of the black long strip particles is 6-7 cm and the width is 2-3 cm; specifically, transparent material is used as the base material and black blank color material, and in a double-roll extrusion machine, black long strip particles with a length of 6-7 cm and a width of 2-3 cm are extruded.

[0047] Ruby-rose particles are wrapped gemstone particles formed by a variety of red powders through a wet turntable, and the particle size of the wrapped gemstone particles is 1-3cm. The various red powders include light red blank color material, dark red blank color material, cattail yellow blank color material, and dark red blank color material, which can be adjusted according to actual needs; the wrapped gemstone particles formed by the wet turntable have a moisture content controlled between 9-10%.

[0048] In the present application, the addition of the long-black leaf particles and the ruby-rose flower particles makes the surface of the tile present a convex effect similar to the leaves and pomegranate flowers of the pomegranate ruby ​​material, which enhances the decorativeness and aesthetics of the tile. Moreover, the long-black leaf particles and the long-black leaf particles, after being fired at a high temperature in the kiln, will cause rapid expansion and form convexities, and the resulting stone effect is realistic.

[0049] In some embodiments of the present invention, in step S3, the pomegranate ruby ​​material is scanned to extract different colors, textures, and layer effects to obtain the original design drawing; through the design drawing, elements such as leaves and roses are extracted, a grayscale image is set, and a carving design drawing is made through a gray-white gradient. Figure 1 :1 Carve and produce the same concave and convex molds as the preset stone surface; Figure 3 As shown, the depression depth of the leaf position in the concave-convex mold is 0.7mm, and the depression depth of the rose position is 0.8mm.

[0050] During the pressing process of the concave-convex mold, the pressure is 6800 MPa and the number of punches is 3.8 times / min; the thickness of the blank is 12.5±0.2 mm and the specification is 900*1800 mm. In step S3, the concave-convex feeling of the tile surface is ensured to match the natural texture of the garnet ruby ​​material. During the pressing process, by controlling the pressure, the number of punches and the thickness of the tile, the texture and shape of the stone can be accurately replicated, thereby forming a realistic three-dimensional effect on the tile surface.

[0051] In some embodiments of the present invention, in step S4, the chemical composition of the scintillation mixture is: ZrO2: 65.55%, SiO2: 33.08%, HfO2: 1.06%, TiO2: 0.08%, Al2O3: 0.05%, loss on ignition: 0.07%, and a small amount of impurities.

[0052] According to the groove design drawing, position and spray digital glue on the glaze lines of the blank, for example, position and spray digital glue on 30.40.50.60.70.80.90 in sequence; then spread the glitter mixture evenly, absorb excess glitter mixture, so that there is no glitter mixture in the areas where digital glue is not sprayed, presenting the effect of dry particles with different thicknesses.

[0053] Therefore, in the present application, by evenly arranging the glitter mixture on the surface of the body, the surface of the tile can not only show the natural beauty of the garnet ruby, but also produce varied visual effects under different lighting conditions.

[0054] In some embodiments of the present invention, in step S5, the matte protective glaze used has a chemical composition of: SiO2: 48.12%, Al2O3: 16.26%, BaO: 14.17%, CaO: 5.49%, ZnO: 5.32%, SrO: 3.64%, Na2O: 3.09%, K2O: 2.87%, MgO: 0.57%, TiO2: 0.14%, loss on ignition: 0.16%, and a small amount of impurities.

[0055] Spray matte protective glaze: glaze amount: 55±1g, specific gravity: 1.42±0.01g / ml, flow rate: 11±1s.

[0056] In some embodiments of the present invention, in step S6, the leaf positions and rose positions in the fired green body are soft-polished, and the groove positions are soft-brushed.

[0057] Specifically, soft polishing is to perform rough polishing, medium polishing, and fine polishing in sequence; rough polishing is to use 5 groups of 1500 mesh and 5 groups of 2000 mesh for rough polishing; medium polishing is to use 10 groups of 240 diamond brushes and 5 groups of 180 rubber brushes for medium polishing; fine polishing is to use 10 groups of 240 mesh fiber brushes for fine polishing.

[0058] The soft brush is a steel wire polishing, which only lightly sweeps the burrs on the grooves without damaging the glaze surface and basically does not affect the surface performance.

[0059] In this application, the surface texture and glossiness of the tiles are further improved by soft polishing and soft brushing.
