Description

Technical Field

[0001] The invention relates to the technical field of ceramic production, and in particular to a preparation method of a three-dimensional colored glazed tile and the three-dimensional colored glazed tile. Background Art

[0002] With the increasing maturity of inkjet printing technology in the building ceramics industry, inkjet printing technology quickly replaced the traditional screen printing and rubber roller printing technology and became the main printing method in the building ceramics industry. However, first of all, inkjet printing controls the printing pattern through inkjet software. As long as the inkjet file is the same, the pattern texture is almost the same, and the inkjet file can be obtained by scanning the products sold on the market. This leads to serious homogeneity of product pattern design on the market, resulting in low added value of products; secondly, because the solid particle fineness of inkjet ink is very small, it is easier to react with glaze, so the color range of inkjet ink is far less than that of previous screen printing, and the color gamut range is too narrow, which leads to greater restrictions on its expression of texture, making it difficult for the product to be personalized in terms of color tone, that is, the pattern color difference of various ceramic products is small. In addition, whether it is the traditional screen and rubber roller printing process or the current inkjet printing process, the pattern effect produced is a flat effect, which is also an important reason for the serious homogeneity of products on the market.

[0003] Therefore, the prior art has defects and needs to be improved and developed. Summary of the invention

[0004] The technical problem to be solved by the present invention is that, in view of the above-mentioned defects of the prior art, a method for preparing three-dimensional colored glazed tiles and three-dimensional colored glazed tiles are provided, aiming to solve the problem in the prior art that the color gamut of inkjet ink is too narrow and the pattern effect is a flat effect, which leads to small differences in pattern colors of various ceramic products.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0006] The first embodiment of the present application provides a method for preparing a three-dimensional colored glazed tile, which comprises:

[0007] Preparing colored ceramic particles of different colors, and mixing the colored ceramic particles of different colors according to a predetermined ratio to obtain a colored ceramic particle mixture;

[0008] Adding basic glaze slurry and printing paste to the colored porcelain particle mixture, and stirring to obtain a printing glaze slurry of a predetermined color system;

[0009] Printing the printed glaze slurry on the ceramic body with the cosmetic soil by screen printing to obtain a glazed body;

[0010] The glazed body is fired at high temperature to obtain a three-dimensional colored glazed tile.

[0011] According to the above-mentioned technical means, the embodiment of the present application forms different patterns by mixing the prepared colored ceramic particles of different colors in different proportions and combining them with screen printing, so that the pattern colors are diverse and a 3D stereoscopic effect is produced on the blank surface, which solves the problem in the prior art that the color gamut of inkjet ink is too narrow and the pattern effect is a flat effect, which leads to small differences in pattern colors of various ceramic products.

[0012] In one embodiment of the present application, colored ceramic particles of different colors are prepared, comprising:

[0013] Prepare colored slurry according to a predetermined colored slurry raw material formula;

[0014] Processing the colored slurry into a colored ceramic plate with a predetermined water absorption rate;

[0015] The colored porcelain plate is crushed and sieved to obtain colored porcelain particles within a predetermined particle size range.

[0016] According to the above technical means, the colored ceramic particles of the embodiment of the present application make up for the deficiency of the narrow color gamut of the current ceramic ink, making the texture expression richer and closer to nature; the color matching of colored ceramic particles of different colors can show more layers, produce a three-dimensional effect, and be more artistic. And because ceramic inkjet ink is oily, when the inkjet volume is large, the ink dots are easy to dissolve each other, which is not conducive to the expression of small details. The use of colored ceramic particles can achieve artistic effects that cannot be achieved by current inkjet technology.

[0017] In one embodiment of the present application, the colored slurry is processed into a colored ceramic plate with a predetermined water absorption rate, comprising:

[0018] The colored slurry is sprayed and granulated, and pressed into a shape to obtain a colored body;

[0019] The colored body is fired to obtain a colored porcelain plate with a predetermined water absorption rate.

[0020] According to the above-mentioned technical means, the embodiment of the present application can ensure that the colored slurry quickly forms tiny particles with uniform size distribution in a short time through spray granulation technology, which not only improves the uniformity of the particles, but also makes the physical and chemical properties of the particles more excellent; through press molding, the density and uniformity of the colored body can be further ensured, laying the foundation for the subsequent firing of high-quality colored porcelain panels.

[0021] In one embodiment of the present application, the predetermined water absorption rate is less than or equal to 0.3%, and the predetermined particle size range is the aperture size of a 60-mesh sieve to the aperture size of a 30-mesh sieve.

[0022] According to the above-mentioned technical means, the water absorption rate fired by the embodiment of the present application is low, indicating that the density of the colored porcelain plate is high, and the tighter the internal structure, the better the physical and chemical stability, which can ensure the stability and dispersibility of the colored porcelain particles in the glaze slurry, thereby improving the durability of the final product. In addition, the low water absorption rate also makes the colored porcelain plate difficult to absorb water, which can reduce the influence of water on the colored porcelain particles and the glaze slurry, and avoid problems such as cracks and deformation during the firing process. The selection of the particle size range directly affects the fineness and layering of the pattern. The aperture of the 60 mesh sieve is relatively small, which can produce a fine effect, and the aperture of the 30 mesh sieve is relatively large, which can produce a rough texture and thus make the pattern of the present application have both fine details and an overall layering. In addition, the present invention can present different patterns and design styles by selecting the particle size within this range.

[0023] In one embodiment of the present application, the colored slurry raw material formula includes: a colored slurry raw material formula and a white slurry raw material formula.

[0024] According to the above technical means, the colored slurry raw material formula of the embodiment of the present application includes a colored slurry raw material formula and a white slurry raw material formula, and then colored porcelain particles and white porcelain particles are prepared to improve the glaze layering.

[0025] In one embodiment of the present application, the raw material formula of the colored slurry comprises, by weight, 80-90 parts of powder for blank, 9-11 parts of inorganic colorant, and 0-10 parts of calcined talc.

[0026] According to the above technical means, the embodiment of the present application obtains colored porcelain particles of different colors by using green body powder, inorganic colorant and calcined talc to prepare colored slurries of different colors, thereby improving the diversity of surface colors of ceramic products.

[0027] In one embodiment of the present application, the white slurry raw material formula comprises, by weight: 80-90 parts of powder for blank, 9-11 parts of zirconium silicate, and 0-10 parts of calcined talc.

[0028] According to the above technical means, the embodiment of the present application uses blank powder, zirconium silicate and calcined talc to prepare a white slurry to obtain white porcelain particles, which are then combined with colored porcelain particles to form a contrasting pattern effect.

[0029] In one embodiment of the present application, the whiteness of the blank powder after firing is greater than or equal to 50 degrees.

[0030] According to the above technical means, the embodiment of the present application uses high-whiteness powder for the blank, which can more clearly present the color of the colored slurry, so that the color reproduction of the colored ceramic particles is higher.

[0031] In one embodiment of the present application, the chemical components of the basic glaze slurry, measured by mass percentage, include:

[0032] Loss on ignition 5-11%, SiO2 47-50%, Al2O3 8-9%, Fe2O3 0-0.2%, CaO 11-13%, MgO 2-3%, K2O 2-4%, Na2O 1-2%, ZnO 4-5%, SrO 4-5%, BaO 2-4%.

[0033] According to the above technical means, the embodiment of the present application obtains high-quality printing glaze slurry through reasonable basic glaze slurry chemical composition.

[0034] The present application also provides a three-dimensional colored glazed tile, wherein the three-dimensional colored glazed tile is prepared by the preparation method of the three-dimensional colored glazed tile as described above.

[0035] The embodiments of the present application achieve beneficial effects:

[0036] First, the embodiment of the present application forms different patterns by mixing the prepared colored ceramic particles of different colors in different proportions and combining them with screen printing, so that the pattern colors are diverse and a 3D stereoscopic effect is produced on the blank surface, which solves the problem in the prior art that the color gamut of inkjet ink is too narrow and the pattern effect is a flat effect, which leads to small differences in the pattern colors of various ceramic products.

[0037] Second, the colored ceramic particles of the embodiment of the present application make up for the shortcoming of the narrow color gamut of the current ceramic ink, making the texture expression richer and closer to nature; the color matching of colored ceramic particles of different colors can show more layers, produce a three-dimensional effect, and be more artistic. And because ceramic inkjet ink is oily, when the inkjet volume is large, the ink dots are easily dissolved, which is not conducive to the expression of small details. The use of colored ceramic particles can achieve artistic effects that cannot be achieved by current inkjet technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 The present invention is a flowchart of a preferred embodiment of a method for preparing a three-dimensional colored glazed tile.

[0039] Figure 2 It is a principle block diagram of a preferred embodiment of a method for preparing three-dimensional colored glazed tiles in the present invention. DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] The embodiment of the present application mixes colored ceramic particles of certain different colors in different proportions, and then combines screen printing or particle stacking to form a specific pattern to produce a 3D stereoscopic effect on the blank surface, thereby achieving a 3D stereoscopic effect in both visual and tactile aspects, making the product personalized, increasing the product added value, and enhancing the product competitiveness.

[0042] See also Figure 1 , Figure 1 1 is a flow chart of the method for preparing three-dimensional colored glazed tiles in the present invention. Figure 1 As shown, the method for preparing the three-dimensional colored glazed tiles according to the embodiment of the present invention comprises the following steps:

[0043] Step S100: prepare colored ceramic particles of different colors, and mix the colored ceramic particles of different colors according to a predetermined ratio to obtain a colored ceramic particle mixture.

[0044] The colored ceramic particles used in the embodiments of the present application are prepared, have strong operability and save energy, and at the same time ensure the stable color development of the encapsulated colorant, and have a wider color gamut expression, which is different from the fused block dry particles in the prior art.

[0045] In the embodiment of the present application, the step of "preparing colored ceramic particles of different colors" in step S100 specifically includes:

[0046] Step S110, preparing colored slurry according to a predetermined colored slurry raw material formula;

[0047] Step S120, processing the colored slurry into a colored ceramic plate with a predetermined water absorption rate;

[0048] Step S130, crushing and screening the colored porcelain plate to obtain colored porcelain particles within a predetermined particle size range.

[0049] In the embodiment of the present application, conventional inorganic pigments for ceramics and conventional powders for blanks are mixed in a certain proportion, and then subjected to wet ball milling, powder spraying granulation, pressing, firing, crushing, and sorting to obtain colored ceramic particles of a certain particle size. Specifically, colored ceramic particles of a specific color are produced according to a pattern design. Ceramic pigments and powders for blanks are mixed in a certain proportion and then wet ball milled into a colored slurry. The colored slurry is spray granulated and dry pressed to form a colored blank. The colored blank is fired under a conventional firing system to form a colored porcelain plate with a certain water absorption rate, and the colored porcelain plate is crushed and sieved to obtain colored porcelain particles of a certain particle size.

[0050] The embodiment of the present application prepares the colored slurry according to the predetermined colored slurry raw material formula, and can accurately control the color to ensure that the color of each colored porcelain particle meets the design requirements, providing a basis for realizing the colorful and diverse pattern colors on the three-dimensional colored glazed tiles. The embodiment of the present application processes the colored slurry into a colored porcelain plate with a predetermined water absorption rate, which can ensure the stability and dispersibility of the colored porcelain particles in the glaze slurry, thereby further affecting the color effect and three-dimensional effect of the final product. The embodiment of the present application crushes and sieves the colored porcelain plate to obtain colored porcelain particles in a predetermined particle size range, ensuring the uniformity and consistency of the particles, which is crucial for the clarity and fineness of the pattern in the screen printing process. At the same time, colored porcelain particles of different particle sizes can produce different visual effects, providing more possibilities for the design of three-dimensional colored glazed tiles. The embodiment of the present application also combines the method of screen printing to form various complex and fine patterns, which are not only colorful, but also have a 3D stereoscopic effect, greatly enhancing the artistic value and ornamental value of ceramic products.

[0051] The colored ceramic particles in the embodiment of the present application make up for the shortcoming of the narrow color gamut of the current ceramic ink, making the texture expression richer and closer to nature; the color matching of colored ceramic particles of different colors can show more layers, produce a three-dimensional effect, and be more artistic. And because ceramic inkjet ink is highly oily, when the inkjet volume is large, the ink dots are easily miscible, which is not conducive to the expression of small details. The use of colored ceramic particles can achieve artistic effects that cannot be achieved by current inkjet technology.

[0052] In one embodiment of the present application, step S120 specifically includes:

[0053] Step S121, spraying and granulating the colored slurry, and pressing and molding to obtain a colored body;

[0054] Step S122, firing the colored body to obtain a colored porcelain plate with a predetermined water absorption rate.

[0055] Specifically, the process control parameters of ball milling, spray granulation, pressing and drying, firing, etc. in the process of making colored porcelain plates are controlled according to large-scale production.

[0056] The embodiment of the present application uses spray granulation technology to ensure that the color slurry quickly forms tiny particles with uniform size distribution in a short time, which not only improves the uniformity of the particles, but also makes the physical and chemical properties of the particles more excellent; through press molding, the density and uniformity of the colored body can be further ensured, laying the foundation for the subsequent firing of high-quality colored porcelain panels.

[0057] In one embodiment of the present application, the predetermined water absorption rate is less than or equal to 0.3%, and the predetermined particle size range is the aperture size of a 60-mesh sieve to the aperture size of a 30-mesh sieve.

[0058] Specifically, the water absorption rate of the colored porcelain plate fired in the embodiment of the present application is ≤0.3%, and the particle size range of the colored porcelain particles obtained after the colored porcelain plate is crushed is from the aperture size of a 60-mesh sieve to the aperture size of a 30-mesh sieve.

[0059] The water absorption rate fired by the embodiment of the present application is low, indicating that the density of the colored porcelain plate is high, and the tighter the internal structure, the better physical and chemical stability is, which can ensure the stability and dispersibility of the colored porcelain particles in the glaze slurry, thereby improving the durability of the final product. In addition, the low water absorption rate also makes the colored porcelain plate difficult to absorb water, which can reduce the influence of water on the colored porcelain particles and the glaze slurry, and avoid problems such as cracks and deformation during the firing process. The selection of the particle size range directly affects the fineness and layering of the pattern. The aperture of the 60 mesh sieve is relatively small, which can produce a fine effect, and the aperture of the 30 mesh sieve is relatively large, which can produce a rough texture and thus make the pattern of the present application have both fine details and an overall layering. In addition, the present invention can present different patterns and design styles by selecting the particle size within this range.

[0060] In the embodiment of the present application, the colored slurry raw material formula includes: a colored slurry raw material formula and a white slurry raw material formula.

[0061] Specifically, the combination of colored slurry raw material formula and white slurry raw material formula can form a contrasting pattern effect. By superimposing and mixing different color slurries, a pattern effect with rich layering can be created.

[0062] The colored slurry raw material formula of the embodiment of the present application includes a colored slurry raw material formula and a white slurry raw material formula, and then colored porcelain particles and white porcelain particles are prepared to improve the glaze layering.

[0063] In one embodiment of the present application, the raw material formula of the colored slurry comprises, by weight, 80-90 parts of powder for blank, 9-11 parts of inorganic colorant, and 0-10 parts of calcined talc.

[0064] Specifically, the inorganic pigment is a conventional ceramic inorganic pigment. As a colorant widely used in the ceramic industry, inorganic pigments have a series of advantages such as high temperature resistance, good weather resistance, strong hiding power, and excellent solvent resistance, so that the colored slurry can present a variety of colors, meeting the market demand for the diversity of colors of ceramic products. Inorganic pigments have no chemical reaction, no volatilization and escape within the ceramic firing temperature range, and do not destroy the mineral structure and cause the color tone to change due to the erosion of the melt. Therefore, the colored slurry can maintain a stable color effect during the firing process and is not easy to fade or discolor. As a hard flux, burnt talc has a fluxing effect at high temperatures.

[0065] In the embodiment of the present application, colored slurries of different colors are prepared by using green body powder, inorganic colorants and calcined talc to obtain colored ceramic particles of different colors, thereby improving the diversity of surface colors of ceramic products.

[0066] In one embodiment of the present application, the white slurry raw material formula comprises, by weight: 80-90 parts of powder for blank, 9-11 parts of zirconium silicate, and 0-10 parts of calcined talc.

[0067] Specifically, in order to improve the glaze level, white porcelain particles are needed in addition to colored porcelain particles, that is, the colored porcelain particles of the embodiment of the present application include white porcelain particles and colored porcelain particles. Zirconium silicate is an important ceramic raw material with excellent opacity and whitening effect.

[0068] In the embodiment of the present application, a white slurry is prepared by using blank powder, zirconium silicate and calcined talc to obtain white porcelain particles, which are then combined with colored porcelain particles to form a pattern effect with sharp contrast.

[0069] In the embodiment of the present application, the whiteness of the blank powder after firing is greater than or equal to 50 degrees. Specifically, the whiteness of the blank powder in the embodiment of the present application after firing alone is ≥50 degrees.

[0070] The embodiment of the present application uses a high-whiteness powder for the blank, which can more clearly present the color of the colored slurry, thereby making the color reproduction of the colored ceramic particles higher.

[0071] like Figure 1 As shown, the method for preparing the three-dimensional colored glazed tiles according to the embodiment of the present invention further includes:

[0072] Step S200: adding basic glaze slurry and printing paste to the ceramic particle mixture, and stirring to obtain a printing glaze slurry of a predetermined color system.

[0073] Specifically, by mixing colored ceramic particles of different colors in different proportions, ceramic particle mixtures of different colors can be obtained, and by adding basic glaze slurry and printing paste to the ceramic particle mixtures of different colors, printing glaze slurries of different colors can be obtained. Printing paste is a paste-like substance prepared from a variety of raw materials through a specific process, and is used for decoration and pattern printing on ceramic surfaces.

[0074] In the embodiment of the present application, the chemical components of the basic glaze slurry, measured by mass percentage, include:

[0075] Loss on ignition 10.04%, SiO2 48.93%, Al2O3 8.99%, Fe2O3 0.16%, CaO 12.86%, MgO2.37%, K2O 3.03%, Na2O 1.52%, ZnO 4.14%, SrO 4.68%, BaO 3.28%.

[0076] In a further embodiment, the chemical components of the basic glaze slurry, measured by mass percentage, include:

[0077] Loss on ignition 10.04%, SiO2 48.93%, Al2O3 8.99%, Fe2O3 0.16%, CaO 12.86%, MgO2.37%, K2O 3.03%, Na2O 1.52%, ZnO 4.14%, SrO 4.68%, BaO 3.28%.

[0078] The embodiment of the present application obtains high-quality printing glaze slurry through reasonable basic glaze slurry chemical composition.

[0079] like Figure 1 As shown, the method for preparing the three-dimensional colored glazed tiles according to the embodiment of the present invention further includes:

[0080] Step S300: Print the printed glaze slurry on the ceramic body with the cosmetic soil by screen printing to obtain a glazed body.

[0081] Specifically, the ceramic body is prepared according to the conventional floor tile production process, that is, conventional powder is pressed and dried and then applied with cosmetic soil to obtain a ceramic body with cosmetic soil applied. The printed glaze slurry is printed on the surface of the ceramic body with cosmetic soil applied by screen printing to form a specific design pattern.

[0082] In one embodiment of the present application, the mesh size is 20 meshes and is thickened 3 times. The screen pattern effect is designed according to the needs. After screen printing, it can be embellished with inkjet printing as needed to make the pattern more rich.

[0083] like Figure 1 As shown, the method for preparing the three-dimensional colored glazed tiles according to the embodiment of the present invention further includes:

[0084] Step S400, firing the glazed body at high temperature to obtain a three-dimensional colored glazed tile.

[0085] Specifically, the printed glaze body is put into the kiln for high temperature firing, and the fired product is surface polished or not polished to obtain a three-dimensional colored glazed tile. Polishing can be performed according to market demand through soft polishing, matte polishing, full polishing and other polishing processes to obtain products with different glaze effects. The process flow chart for preparing three-dimensional colored glazed tiles is as follows: Figure 2 shown.
