[0046] Figure 1 is a flow chart of a preferred embodiment of a method for preparing a marble ceramic tile with a stone gloss in the application.

[0047] Figure 2 、 Figure 3 and Figure 4 are effect schematic diagrams of the marble ceramic tile prepared in the application. DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of the application more clear and explicit, the application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the application and do not limit the application.

[0049] The marble stone glosses in the market vary in height, and the gloss changes greatly after use, and the stain resistance is poor. The gloss of the existing marble ceramic tile is generally about 20 degrees, 40 degrees, 60 degrees and 90 degrees, and the thickness is generally 12 mm. Compared with real stone, these glosses have a certain distortion. The marble ceramic tile with a gloss of less than 80 degrees has insufficient product clarity, weak detail level, poor transparency and rough stone grain lines. The high-gloss marble ceramic tile with a gloss of 90 degrees will cause the product surface to be like a mirror, losing the water and oil feeling of the stone itself, and the product hand feeling is insufficient. At the same time, the product structure prepared by the previous preparation process is single, the surface effect is greatly different from that of real stone, the product thickness is thick, the processing difficulty is great, and thus the use in the construction and decoration industry is limited.

[0050] The marble ceramic tile provided by the application has the colorful color of the stone itself, the beautiful and natural texture, and the stone grain texture close to the stone itself, especially the jade-like stone series and the stone after the extrusion fault of nature. The product prepared according to the process of the embodiment of the application can eliminate the small impurity defects of the stone itself, retain the fine texture of the natural growth of the stone itself, and have high transparency and the water and oil feeling of the stone itself.

[0051] A marble ceramic tile preparation method with stone gloss is described below with reference to the accompanying drawings. In view of the fact that the marble ceramic tile in the prior art mentioned in the background art still has a certain visual difference from real stone, resulting in poor stone authenticity of the marble ceramic tile, the present application provides a marble ceramic tile preparation method with stone gloss. In the method, a ceramic body to which a base glaze has been applied is subjected to inkjet printing according to a previously obtained stone texture pattern, to obtain a pattern decoration layer. The ink used in the inkjet printing includes matte fine carving digital ink and high-temperature matte white ink. A face glaze is applied on the pattern decoration layer, so that the face glaze and the pattern decoration layer form an ink discharge phenomenon, and the ink discharge phenomenon is covered under the glaze layer formed by the face glaze. The ceramic body to which the face glaze has been applied is processed into a marble ceramic tile with stone gloss. The present application utilizes the superposition of two types of digital ink, matte fine carving digital ink and high-temperature matte white ink, and the combination of ink performance and glaze performance after glazing, to form an ink discharge phenomenon. The ink discharge reaction occurs under the glaze layer, and then a surface depression effect from the inside to the outside is produced after glazing, which can visually achieve the effect of real stone surface sedimentation and erosion.

[0052] The present application provides a marble ceramic tile preparation method with stone gloss, as shown in Figure 1 The marble ceramic tile preparation method with stone gloss includes:

[0053] Step S100, a ceramic body to which a base glaze has been applied is subjected to inkjet printing according to a previously obtained stone texture pattern, to obtain a pattern decoration layer. The ink used in the inkjet printing includes matte fine carving digital ink and high-temperature matte white ink.

[0054] Specifically, the digital ink obtained by superimposing matte fine carving digital ink and high-temperature matte white ink according to different gray scales has oiliness and wateriness. The gray scale range is 1-100. When using matte fine carving ink, the kiln firing temperature needs to be adapted. The same ink fired in different kilns will be bright in some cases and poor in fine carving effect in some cases, and is not fine enough. Therefore, the ink formula needs to be adjusted according to the actual situation.

[0055] The embodiment of the present application sprays the glaze when the ink is not dry, and passes through a 20-meter drying kiln before spraying the glaze, and is dried at a temperature of 80-120°C for 1.5-2 min. The water on the surface layer of the ink is evaporated at high temperature, and the oiliness of the fine carving ink on the surface layer is reserved. When the glaze is sprayed, the water and oil incompatible characteristics of the water property of the glaze and the oil property of the ink are used, and the glaze is sprayed layer by layer until the glaze completely covers the surface. The glaze will form a physical ink removal phenomenon in the intermediate layer below the surface layer of the glaze and above the surface of the ink during the initial contact with the ink, and achieve a stone grain effect generated from the inside. The conventional marble ceramic tile does not superimpose the matte fine carving digital ink and the high-temperature matte white ink, and does not have a professional fine operation. The traditional marble generally adopts an inkjet combined with a flat printing process to produce, and after the glaze is applied, the glaze and the ink cannot form a physical ink removal phenomenon.

[0056] The embodiment of the present application superimposes the different gray scale texture information of the matte fine carving digital ink and the high-temperature matte white ink, uses the water and oil properties of the glaze, and uses the water and oil incompatible characteristics below the glaze layer to achieve a deep and light differential ink removal effect, and after glazing, the fine stone grain texture naturally grown by the stone itself for thousands of years is reproduced, the stone grain line fineness reaches 0.1 mm, and the marble ceramic tile is more realistic.

[0057] In the embodiment of the present application, the obtaining step of the stone texture pattern comprises:

[0058] A scanning device with a resolution of 3200 dpi is used to scan the surface of the target stone to obtain an original scanning image, and the original scanning image is used as the stone texture pattern.

[0059] Specifically, the embodiment of the present application uses a scanning device with a resolution of 3200 dpi to scan all the information on the surface of the target stone, and 100% of the texture information of the stone itself is reserved.

[0060] In addition, the original scanning image is taken as the stone texture pattern in the embodiment of the application. In order to avoid slow reaction, lag, low efficiency and the like of a file in a design process, a conventional file usually reduces the file definition to improve the work efficiency without affecting inkjet printing. For example, the same design file has an original material of 2GB size. Because the file content is rich and the file is large, the design computer processes the file slowly in the design process. Without affecting the clear color of the product 1 meter away, the file resolution is reduced to 360dpi or 300dpi, and the file processing speed is doubled. Through the operation conversion and adjustment of reducing the detail differentiation, the same file pattern reduces the file information value, so that the finally designed file has only 10-15G. The file size can reflect the richness of the file content and the number of details. The embodiment of the application adopts a high-resolution scanning device to scan the surface of the target stone, and retains the original scanning image, so that the stone texture pattern with rich details can be obtained, and the small impurity defects contained in the stone itself can be eliminated, the natural beauty can be improved, the stone grain line direction and the stone texture overlap can be designed according to the stone itself texture, and the stone grain line precision error is less than or equal to 1 pixel.

[0061] As shown in Figure 1 the marble tile with stone glossiness preparation method further comprises:

[0062] In step S200, the face glaze is applied on the pattern decoration layer, so that the face glaze and the pattern decoration layer form the ink discharge phenomenon, and the ink discharge phenomenon is covered under the glaze layer formed by the face glaze.

[0063] In an embodiment of the application, the step S200 specifically comprises: adopting a swing pressure glaze spraying cabinet to apply the face glaze on the pattern decoration layer, so that the face glaze and the pattern decoration layer form the ink discharge phenomenon, and the ink discharge phenomenon is covered under the glaze layer formed by the face glaze; wherein the pressure control of the swing pressure glaze spraying cabinet is 1-1.2MPa, the glazing specific gravity is 1.38-1.40, and the glazing amount is 130-190g / m 2 .

[0064] Specifically, the face glaze of the embodiment of the application adopts the swing pressure glaze spraying cabinet, adopts 6-8 spray guns to swing back and forth, and the pressure is 1-1.2MPa. The ink discharge reaction of the digital ink and the face glaze is covered under the glaze layer in a uniform state. The spray gun of the swing pressure glaze spraying cabinet can swing back and forth, so that the sprayed face glaze is naturally stacked, and then the ink and the face glaze are combined to generate stacked crystals during firing. Because the ink discharge reaction occurs under the glaze layer, this process will produce a concave feeling from the inside to the outside after glazing. The surface of the conventional marble tile is all increased on the upper layer of the glaze layer to increase the concave feeling; the application can achieve the effect of real stone surface deposition erosion in vision.

[0065] The marble ceramic tile with stone glossiness is produced by special digital ink superposition and the combination of ink performance and glaze performance after glazing, and the texture color and stone grain line texture of the marble ceramic tile are close to real stone materials.

[0066] In the embodiment of the present application, the chemical components of the surface glaze include, by mass percentage:

[0067] SiO2 50-54%, Al2O3 17-22%, CaO 5-8%, MgO 1-3%, Ka2O 4-6%, Na2O2-4%, ZnO 5-8%, BaO 7-11%, SrO 2-4%.

[0068] Specifically, the wear resistance of the surface glaze is grade 4, and the wear resistance test data is 12000 revolutions.

[0069] The embodiment of the present application uses glaze with high hardness and high transparency, which improves the transparency and hardness of the product after polishing.

[0070] As shown in Figure 1 The method for preparing the marble ceramic tile with stone glossiness further includes:

[0071] Step S300, processing the ceramic body to which the surface glaze has been applied into the marble ceramic tile with stone glossiness.

[0072] In the embodiment of the present application, the step S300 specifically includes:

[0073] Step S310, firing the ceramic body to which the surface glaze has been applied under the condition that the firing temperature is 1130-1230℃ and the firing time is 60-90 minutes, to obtain the fired semi-finished product;

[0074] Step S320, polishing the fired semi-finished product by using a polishing device;

[0075] Step S330, waxing the fired semi-finished product after polishing, to obtain the marble ceramic tile with stone glossiness.

[0076] Specifically, the firing temperature of the kiln of the embodiment of the present application matches the surface glaze, the SiO2 in the surface glaze accounts for 50-54%, the Al2O3 accounts for 17-22%, the kiln ring temperature is controlled at 1130-1230℃, and the kiln firing period is about 60-90 minutes, so as to ensure that the glaze and the ink have certain quality change time in different temperature ranges.

[0077] The firing process of the embodiment of the application can form a good combination between the surface glaze and the ceramic body, and enhance the stability of the whole; the polishing can remove the tiny defects on the surface of the glaze, so that the glaze is smoother and brighter, the polished glaze has a gloss similar to that of stone, and the visual effect of the ceramic product is improved; the polished glaze forms a hard protective layer, and the wear resistance is enhanced; the polished glaze is smoother, and dirt and dust are not easily adsorbed. The waxing can form a protective film on the surface of the glaze, prevent the glaze from being worn and contaminated, and maintain the gloss of the glaze.

[0078] In the embodiment of the application, the step S320 specifically comprises:

[0079] Step S321, first glaze polishing is performed by using the 600-mesh elastic abrasive block, the 800-mesh elastic abrasive block and the resin brush on the first polishing equipment;

[0080] In this step, the 600-mesh and 800-mesh elastic abrasive blocks have fine particle size and high hardness, and obvious fiber scratches are generated when the surface thickness of the glaze layer is cut and shaved; the resin brush has high density and soft strength. The fiber scratches can be repaired during the brushing and polishing process.

[0081] Step S322, second glaze polishing is performed by using the 800-mesh elastic abrasive block on the second polishing equipment;

[0082] In this step, the 800-mesh elastic abrasive block is used for the second glaze polishing to ensure that the product brick surface is evenly polished.

[0083] Step S323, third glaze polishing is performed by using the resin brush and the 800-mesh elastic abrasive block on the third polishing equipment;

[0084] In this step, the purpose of the third glaze polishing is to repair the surface fiber scratches of the product brick and enhance the grease gloss.

[0085] Step S324, fourth glaze polishing is performed by using the 1000-mesh elastic abrasive block, the 1500-mesh elastic abrasive block, the 2000-mesh elastic abrasive block and the 3000-mesh elastic abrasive block on the fourth polishing equipment.

[0086] In this step, the fourth glaze polishing mainly controls the uniformity and gloss of the surface flexibility.

[0087] Specifically, the embodiments of the application adopt different superimposed combinations of new elastic grinding blocks and special oily resin brushes. The glazing process includes four glazing devices, the combination of the first glazing device is: 600 mesh elastic grinding block, 800 mesh elastic grinding block, pure resin brush; the combination of the second glazing device is: 800 mesh elastic grinding block; the combination of the third glazing device is: resin brush, 800 mesh elastic grinding block, for increasing the surface oiliness; the combination of the fourth glazing device is: 1000 mesh elastic grinding block, 1500 mesh elastic grinding block, 2000 mesh elastic grinding block and 3000 mesh elastic grinding block.

[0088] The glazing process of the application is that the coarse polishing adopts the superposition of elastic bright grinding blocks and resin brushes, so as to achieve the effect of repairing glaze marks while grinding, reduce the fiber marks on the glaze, increase the flatness of the glaze, and then improve the light refraction rate of the product and increase the clearness of the product. The conventional glazing process is to use elastic grinding blocks first and then use brushes, which cannot repair glaze marks while grinding.

[0089] In an embodiment of the application, the chemical components of the elastic grinding block and the resin brush each include, by mass percentage:

[0090] phenolic resin powder 35-45%, diamond powder 15-20%, corundum powder 5-10%, green silicon carbide powder 5-10%, zinc oxide powder 10-15%, cerium oxide powder 15-20%, titanium salt 4-6%, zinc stearate 2-4% 。

[0091] The material properties of the resin brush include: first, the resin elastic material has high elasticity and strong resilience, and can restore to its original state after being stressed. Second, it has good wear resistance and can resist long-term physical wear. Third, it has good corrosion resistance and good resistance to acids, alkalis and other chemicals.

[0092] The industry conventional grinding block has many particle impurities with different hardness in the same plane. In the use process, the grinding amount seems the same, but after magnifying, it can be found that the fiber marks caused by the particles with high hardness and the particles with low hardness are different in depth. Similarly, the brush composition also has a high proportion of other particles, which leads to a low proportion of resin, and the composition structure of the grinding block and the brush is different. Therefore, the filling is not complete in the later fine polishing repair process. This causes the light to scatter in the brick surface during propagation, resulting in a cloudy and white phenomenon. This condition leads to poor product clarity and average permeability.

[0093] The application uses high-purity and low-impurity grinding blocks, and the surface composition is basically consistent. Moreover, the chemical composition of the grinding block and the brush is the same. The fiber scratches generated during the grinding process are close in depth, and the high-purity resin fiber brush fills and repairs the fiber scratches, increases the flatness of the surface layer, reduces the light scattering rate, improves the penetration rate, and achieves the effect of clear and comfortable gloss and lubricated hand feeling. Therefore, the application can better fill and repair the surface of the product.

[0094] The application embodiment controls the polishing effect when polishing the glaze, achieves high penetration of the product, can produce fine lines of stone lines and digital ink, and visually produces the stone sediment concave-convex feeling presented from the inside. Moreover, the surface touch of the marble ceramic tile after polishing the glaze is closer to the stone with a sense of age, which is qualitatively different from the traditional full polishing touch. The marble ceramic tile provided by the application is closer to the original ecological stone texture.

[0095] In the application embodiment, the step S330 specifically includes: using the same wax water to wax twice on the fired semi-finished product after polishing the glaze, to obtain the marble ceramic tile with stone gloss; wherein the wax water used for waxing includes: high-permeability small-molecular-weight modified silicone, medium-molecular-weight modified silicone, large-molecular-weight modified silicone, environmentally friendly solvent oil, high-efficiency organic tin curing agent, and other modified additives. The conventional high-light product in the industry generally uses two different types of wax water, namely, anti-fouling wax water and bright wax water, in combination.

[0096] Specifically, after the two waxing processes, the marble ceramic tile surface can maintain water lubricity, thereby improving the durability of the product. Moreover, after use and wear, there will be no defects such as reflection, large gloss contrast at frequently worn parts. The main components of the wax water used for waxing include: high-permeability small-molecular-weight modified silicone, medium-molecular-weight modified silicone, large-molecular-weight modified silicone, environmentally friendly solvent oil, high-efficiency organic tin curing agent, and other modified additives. Compared with conventional wax water, the wax water used in the application embodiment has good permeability, better penetration, better slip resistance, better anti-fouling property, and better durability.

[0097] In one specific implementation, the ceramic powder is pressed and formed, and dried to obtain a ceramic body; after the ceramic body is subjected to a cooling treatment, a high-temperature matte base glaze is applied, and then sent to a drying kiln for drainage and temperature control. After the dried ceramic body is subjected to 3D inkjet printing, it is again sent to the drying kiln for drainage and temperature control. After the inkjet-printed ceramic body is glazed using a high-pressure swing glaze cabinet, it is fired, and the fired semi-finished product is polished, waxed, and edge-ground to obtain a marble ceramic tile.

[0098] The application embodiment also provides a marble ceramic tile, which is prepared by the marble ceramic tile preparation method with stone gloss as described above.

[0099] The marble ceramic tile produced by the application has rich details, colorful colors, and beautiful and natural textures, and is closer to the original ecological stone.

[0100] The polishing and waxing method of the application is suitable for products with different gloss, and the prepared product is one level higher in stain resistance and permeability compared to the traditional polishing and waxing method. The polishing method of the application reduces light scattering, so the light permeability is better. The wax water used in the application has better stain resistance than traditional wax water, and the permeability after solidification is also better. As shown in Table 1, Table 1 shows the performance comparison of products polished by different polishing processes for products with different gloss.

[0101] Table 1

[0102]

[0103]

[0104] In the embodiment of the application, the thickness of the marble ceramic tile is 9 mm, and the gloss of the marble ceramic tile is 65-70 degrees.

[0105] Specifically, the gloss of the product after glazing before waxing reaches about 65-70 degrees, while having high transparency and wateriness, the surface hardness reaches 6-7 levels, the wear resistance is 4 levels, and the stain resistance is good. That is, the gloss of the marble ceramic tile product provided in the embodiment of the application is 65-70 degrees.

[0106] The marble ceramic tile produced in the embodiment of the application has a thickness of 9 mm, which is thinner than the conventional marble ceramic tile, has wider use, and is closer to the original ecological stone. The operability range of the marble ceramic tile with a thickness of 9 mm is wider than that of the marble ceramic tile with a thickness of 12 mm, and the selectability is more, and the convenience of paving operation is improved. In addition, the production of 9 mm marble ceramic tile consumes less natural resources than the production of 12 mm marble ceramic tile.

[0107] Moreover, the application is a process for simulating the surface effect of original stone, and the hand feeling, visual effect, surface recessed corrosion points and stone line can present the fine cracks produced by long-term extrusion of stone. The gloss of the existing imitation original stone ceramic tile cannot reach 65-70 degrees, and the gloss of the application can reach 65-70 degrees. The application has an oily and watery gloss after glazing, and the surface is not a mirror surface, but has recessed corrosion points, as shown in Figure 2 、 Figure 3 and Figure 4 .

[0108] The application achieves the following effects:

[0109] First, the surface of the conventional marble tile product is incompatible with touch and gloss, transparency and visual water and oil feeling. The marble tile prepared by the embodiment of the application has clear transparency, touch close to real stone, and visual water and oil feeling.

[0110] Second, the embodiment of the application uses the superposition of matte fine carving digital ink and high-temperature matte white ink to reproduce the fine stone texture naturally grown by stone for thousands of years, with a stone line fineness of 0.1 mm, making the marble tile more realistic.

[0111] Third, the 9mm-thick marble tile produced by the embodiment of the application reduces the consumption of raw materials and fuel.

[0112] Fourth, the conventional 12mm-thick marble tile has large specifications and weight, and is difficult to process and operate. The 9mm-thick marble tile of the embodiment of the application solves the above problems.

[0113] Fifth, the preparation method of the application is not only suitable for 9mm-thick marble tiles, but also can be used in other glaze products, thereby improving the clarity and transparency of other glaze products.

[0114] The application provides a marble tile with stone gloss and a preparation method thereof. The preparation method comprises: performing inkjet printing on a ceramic body to which a base glaze has been applied according to a previously obtained stone texture pattern, to obtain a pattern decoration layer, wherein the ink used in the inkjet printing comprises matte fine carving digital ink and high-temperature matte white ink; applying a surface glaze on the pattern decoration layer, so that the surface glaze and the pattern decoration layer form an ink discharge phenomenon, and the ink discharge phenomenon is covered under a glaze layer formed by the surface glaze; and processing the ceramic body to which the surface glaze has been applied into a marble tile with stone gloss. The application uses the superposition of matte fine carving digital ink and high-temperature matte white ink, and the combination of ink performance and glaze performance after glazing, to form an ink discharge phenomenon. The ink discharge reaction occurs under the glaze layer, thereby producing a surface depression feeling from the inside to the outside after glazing, and achieving the effect of real stone surface deposition erosion in vision.

[0115] It should be understood that the application is not limited to the above examples, and can be improved or changed by those skilled in the art according to the above description, and all these improvements and changes shall belong to the protection scope of the claims of the application.
