Description

Technical Field

[0001] The invention relates to the technical field of ceramic tiles, in particular to a diamond flash glaze, a flash marble ceramic tile and a preparation process thereof. Background Art

[0002] Traditional ceramic tiles, such as marble tiles, have difficulty achieving the natural stone effects sought by consumers and designers. With the continuous improvement of people's living standards, ceramic production has also experienced rapid development. The marble glaze formulation plays an important role in the firing process of marble tiles. The composition of marble glaze is similar to a glass crystal layer. This special glass crystal layer can be considered to be composed of numerous frit particles and quartz crystals arranged in a variety of crystalline shapes.

[0003] In the preparation process of marble glaze, some special diamond powder, quartz particles, glitter dry particles, zircon sand particles, feldspar sand particles, etc. are usually added to interact with the marble glaze to present a specific glitter effect. The degree of reaction between the components of the glitter marble glaze mixed and melted in proportion and the uniformity of the melt need to be studied. As a type of dry granular glaze for marble tiles, the diamond glitter marble glaze can emit a starlight effect that is as bright and dazzling as starlight under a refractive state through the diamond dry particle crystal particles printed on the glaze surface, thus being favored by consumers. However, in the prior art, the process of preparing the diamond glitter marble glaze has the problem of uneven dispersion of the body and the surface glaze. Therefore, it is impossible to form a glitter marble glaze / ceramic tile product with excellent decorative effect. It is even easy to cause the performance of the marble glaze to change, resulting in a decrease in the other properties of the tile, such as glossiness and hardness. Summary of the Invention

[0004] The main purpose of the present invention is to provide a diamond flash glaze, a flash marble tile and a preparation process thereof, aiming to improve the technical problems that the existing diamond flash marble has poor decorative effect and other properties.

[0005] To achieve the above object, the present invention provides a diamond flash glaze, which is prepared by mixing and ball-milling the following raw materials, calculated by weight: 30-50% potassium feldspar, 10-15% quartz powder, 10-15% barium carbonate, 1-5% diamond powder, 1-2% modified zircon sand, 1-3% albite ore particles, 10-13% wollastonite, 1-6% fluorite powder, 3-13% calcined zinc oxide, 4-8% kaolin, 1-3% flash dry particles, and 5-10% water.

[0006] The diamond glitter glaze provided in this solution can be used in the preparation of marble slabs. During the preparation, the diamond glitter glaze can be printed by an inkjet machine. The decorative effect of the prepared glitter marble slabs / ceramics is closer to the fine crystals and texture effects of natural marble. At the same time, it also has a high hardness, with a hardness level of 5 and an acid and alkali resistance level of A. It has a wide range of application scenarios and can be used as floor tiles, washbasins or background walls.

[0007] The Diamond Glitter Glaze in this proposal is made from a combination of specialized mineral and chemical raw materials through multiple production processes. Diamond powder, quartz powder, dry glitter particles, and zircon sand particles are combined to form a diamond glitter nucleus. This diamond glitter nucleus offers stable performance, high hardness, anti-slip properties, and wear resistance, along with enhanced transparency and glitter, creating a multi-dimensional refraction. This can be used as a reinforcing material for large slab / ceramic tile glazes, ultimately creating a glittering, granular effect on the tile, enhancing its wear resistance, hardness, and thermal stability. In addition to the aforementioned raw materials, a certain amount of printing paste and ink can also be added to the Diamond Glitter Glaze. The albite ore particles referred to in this proposal are 100-150 mesh, while conventional albite powder has a mesh size of 320-400.

[0008] Preferably, the flash dry granules comprise the following raw materials, by weight: 2-8 parts diopside, 10-13 parts quartz, 10-12 parts calcined kaolin, 1-3 parts boric acid, 3-6 parts kaolin, 20-32 parts albite, 1-3 parts barium carbonate, 3-7 parts talc, 4-6 parts zinc oxide, 4-5 parts spodumene, and 1-6 parts calcium phosphate. The flash dry granules are obtained by melting, water quenching, drying, pulverizing, granulating, and screening these raw materials, and exhibit a good flash effect. By weight percentage, the flash dry granules comprise the following oxides: 35-40% SiO2, 10-15% Al2O3, 4-6% ZnO, 3-7% MgO, 1-6% CaO, 5-12% Na2O, 5-15% K2O, 1-5% BaO, and 1-3% Li2O.

[0009] Preferably, the diamond flash glaze comprises the following components by weight percentage: SiO2 50-55%, Al2O3 13-15%, MgO 1-4%, CaO 5-15%, Na2O 1-6%, K2O 2-4% and BaO 4-17%.

[0010] Preferably, zircon sand is calcined at 1100-1170°C, then acid-washed and soaked in water for 1-2 hours, ball-milled for 3-5 minutes, dried, and passed through an 80-mesh sieve to obtain modified zircon sand. In this solution, hydrochloric acid is used for acid washing. The acid-washed modified zircon sand obtained after this process has a spherical shape, changing from the original rhombus shape, and has a more uniform refractive index. Furthermore, unlike the original zircon sand, the acid-washed modified zircon sand has more stable properties, with a specific gravity of approximately 4.65-4.79 and a refractive index of 1.97-2.10.

[0011] In addition, the present invention also proposes a preparation process of a flashing marble tile, comprising the following steps: S1. applying a glaze on the surface of the blank, and then inkjet printing a preset pattern; S2. continuing to apply the diamond flash glaze as described in any of the above items on the blank after step S1, and obtaining the flashing marble tile after calcination.

[0012] The production process for shimmering marble tiles is relatively simple, and the diamond shimmer glaze can be easily applied to the surface of the tile body. Compared to ordinary tiles, the resulting shimmering marble tiles have better wear resistance, hardness, and thermal stability, with a more prominent shimmering crystal effect and less fading. When inkjet printing diamond shimmer glaze, the varying shades of the pattern during inkjet printing will result in different refraction effects on the shimmering dry particles. Dark patterns reflect less shimmering gloss, while dark patterns reflect more shimmering gloss. Therefore, the shimmering gloss more closely resembles the varying shades of natural stone.

[0013] Preferably, the diamond powder is crushed by ball milling to a size of less than 400 mesh. The diamond powder is then ball milled again by high-speed ball milling to obtain a diamond powder with a particle size of less than 400 mesh and a density of about 3420-3510 kg / m 3 , chemical properties are stable, and it has good acid and alkali resistance.

[0014] Preferably, in step S2, the calcination temperature is 1200-1220°C and the calcination time is 60-70 minutes. Using the above parameters to calcine the glitter marble tiles, the tiles have a moderate gloss and the gloss of the diamond glitter glaze on the surface is closer to the glitter effect of natural stone.

[0015] Preferably, the top glaze comprises the following raw materials, measured by weight percentage, which are mixed and then ball-milled: 35-45% albite powder, 3-5% calcined zinc oxide, 10-20% quartz, 4-10% kaolin, 1-5% talc, 6-10% barium carbonate, and 10-15% zirconium silicate. The top glaze also includes 0.1-0.15% methyl cellulose and 0.2-0.4% sodium tripolyphosphate, representing the total weight of the top glaze raw materials. The top glaze layer in this embodiment serves as an intermediate transition layer between the body layer and the diamond glitter glaze layer. Using these raw materials ensures a superior glaze finish and better displays the glittering effect of the diamond glitter glaze on the upper layer.

[0016] Preferably, the glaze comprises the following components by weight percentage: SiO2 30-35%, Al2O3 12-15%, MgO 1-5%, ZnO 3-5%, CaO 1-5%, Na2O 5-10%, K2O 8-10%, ZrO2 10-15% and BaO 6-10%.

[0017] The present invention also provides a shimmering marble tile produced using any of the aforementioned processes for producing shimmering marble tiles, comprising, from bottom to top, a body layer, a glaze layer, an inkjet pattern layer, and a diamond shimmering glaze layer. This shimmering marble tile employs the aforementioned processes for producing shimmering marble tiles and has the same beneficial effects as the aforementioned processes, which are not further detailed here.

[0018] Compared with existing technologies, the diamond glitter glaze and glitter marble tiles of the present invention offer the following advantages: The stable diamond glitter crystal nuclei formed by adding diamond powder, quartz powder, glitter dry particles, and zircon sand particles to the glaze layer exhibit a superior glitter effect. Furthermore, during firing, the glitter dry particles, zircon sand, and albite particles in the glaze layer are mixed and adsorbed onto the tile surface, making it easier to control the properties of the glaze slurry, resulting in a high hardness and wear resistance in the fired glaze layer. High-quality tiles made with this diamond glitter glaze have a kiln gloss of 50-65 degrees (compared to the 20-30 degree gloss of conventional marble tiles). Polishing further enhances the glitter crystals, resulting in a superior glitter effect. The anti-slip coefficient can reach R11-R12, exceeding national standards. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] Comparative Example 1

[0069] The preparation steps and parameters in this comparative example are the same as those in Example 1, except that: in this comparative example, no flash dry particles are added, and the amount of potassium feldspar is adjusted to 39.5%.

[0070] Comparative Example 2

[0072] Comparative Example 3

[0073] The preparation steps and parameters in this comparative example are the same as those in Example 1, except that the zircon sand in this comparative example is not modified.

[0074] Comparative Example 4

[0075] This comparative example uses conventional marble glaze, to which diamond powder is added. The specific raw materials and amounts are: potassium feldspar 30%, quartz 12%, barium carbonate 5%, barium sulfate 1%, diamond powder 2%, sodium feldspar 10%, wollastonite 10%, dolomite powder 5%, calcined zinc oxide 7%, kaolin 8%, and aluminum oxide 10%.

[0076] The performance of the flash marble tiles prepared in Examples 1-4 and Comparative Examples 1-4 was tested, and the specific test results are shown in the following table:

[0077]

[0078] Note: This scheme uses a combination of refractive index and glossiness to reflect the glitter effect of glitter marble tiles. The higher the refractive index and the relatively higher the glossiness (the glossiness here should not be too high, otherwise it will cause light pollution), the better the corresponding tile glitter effect, and vice versa.

[0079] The test results in the table above show that the shimmering marble tiles produced in this solution have a glossiness of over 50°, a refractive index of over 1.3, a wear resistance of over 1500 rpm, a hardness of over 3, and a slip resistance of over B. These shimmering marble tiles exhibit excellent shimmering properties, hardness, slip resistance, and wear resistance. The test results of Example 1 and Comparative Example 1 show that without the addition of shimmering dry particles, the shimmering effect of the tiles is relatively weakened, while the hardness, wear resistance, and slip resistance are also somewhat reduced. The test results of Example 1 and Comparative Example 2 show that without the addition of modified zircon sand, the hardness, wear resistance, and slip resistance of the tiles are somewhat reduced. The test results of Example 1 and Comparative Example 3 show that when unmodified zircon sand is used, the shimmering effect, hardness, and wear resistance of the tiles are reduced. The test results of Comparative Example 4 show that when conventional marble glaze is combined with diamond powder, the resulting marble tiles have a poor shimmering effect, and their other properties are inferior to those of the shimmering marble tiles in this solution.
