Description

Technical Field

[0001] The invention relates to the technical field of ceramics, and in particular to a vertical sculpture glaze, simulated stone ceramic tile and a preparation method thereof. Background Art

[0002] Currently in the ceramic tile industry, soft-polished simulated stone ceramic tiles are very popular because of their warm surface texture and soft glaze. These products are generally prepared by using a surface glaze setting with a glossiness of about 30° and auxiliary fiber module treatment, or by post-polishing and waxing treatment. However, this type of simulated stone ceramic tile cannot achieve the delicate texture of traditional simulated stone ceramic tiles, and has the defects of being not scratch-resistant and not anti-fouling, and cannot be used in some kitchens and bathrooms that are easily scratched or dirty. Summary of the invention

[0003] Based on the defects of the prior art, the purpose of the present invention is to provide a three-dimensional carving glaze. Based on its special chemical composition, this product has an ideal three-dimensional carving effect when used in the preparation of simulated stone tiles, with fine texture and high stone simulation. At the same time, the product has high wear resistance, surface stains can be easily removed, and has a good anti-fouling effect.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A glaze for vertical sculpture, comprising the following chemical components in percentage by weight:

[0006] Al2O3 18.12~20.15%, SiO2 50.14~53.51%, K2O 0.81~1.55%, Na2O3.59~5.85%, CaO 6.32~8.28%, MgO 3.82~5.65%, SrO 3.16~5.45%, BaO1.12~2.36, ZnO3.86~5.45%, the balance is loss on ignition and some trace components.

[0007] Preferably, the glaze comprises the following raw materials in parts by weight:

[0008] 20-35 parts of albite, 5-10 parts of calcined kaolin, 4-8 parts of calcined zinc oxide, 5-10 parts of strontium carbonate, 3-10 parts of magnesium-containing frit, 3-6 parts of calcined alumina, 5-15 parts of calcium-containing frit, 10-20 parts of lithography frit, 5-15 parts of washed soil, 5-10 parts of burned talc and 3-7 parts of wollastonite.

[0009] Preferably, the sculpture frit comprises the following chemical components in percentage by mass: Al2O3 17.56-22.12%, SiO2 48.14-53.51%, K2O 0.51-1.55%, Na2O 2.89-4.35%, CaO 7.12-9.68%, MgO 2.82-4.15%, ZnO 2.86-4.45%, BaO 8.19-10.54%.

[0010] In the sculpture glaze described in the present invention, zinc oxide and strontium oxide are introduced as specific components for improving light transmittance and crystal texture, and the relative content of silicon dioxide is controlled, which can effectively improve the clarity of the surface texture and the coloring effect of the product. At the same time, due to the high content of magnesium oxide, calcium oxide and barium oxide, when applied to the preparation of ceramic tile firing, the solvent effect of the overall formula is good, the obtained glaze has higher transparency and good wear resistance, and the glaze can also take into account the anti-fouling effect after polishing.

[0011] When selecting raw materials for preparing freehand glaze, on the one hand, strontium carbonate is used as a sintering flux to lower the firing temperature of the entire material and optimize the high-temperature fluidity of the formula. Combined with a zinc source, the smoothness and fineness of the overall glaze can be improved. On the other hand, the calcium and magnesium content in the raw materials are set at a relatively high level, which allows these two elements to form calcium-magnesium feldspar crystal phases during the sintering process, further improving the fluidity and reactivity of the material in a high-temperature environment. In addition, the three types of frits can form tiny crystals during the sintering process, ensuring that the glaze is resistant to thermoplasticity during firing, and reducing problems such as pores and exhaust on the glaze, ultimately achieving a three-dimensional carving effect and significantly improving the anti-fouling effect.

[0012] Preferably, the calcium-containing frit comprises the following chemical components in percentage by mass: Al2O3 16.58-19.94%, SiO2 54.34-58.65%, K2O 1.65-2.56%, Na2O 2.35-3.58%, CaO 16.62-18.50%, and the remainder is loss on ignition and some trace components.

[0013] Preferably, the magnesium-containing frit comprises the following chemical components in percentage by mass: Al2O3 13.45-15.64%, SiO2 50.24-56.67%, K2O 2.14-3.15%, Na2O 3.85-5.35%, MgO 15.87-19.54%, and the remainder is loss on ignition and some trace components.

[0014] Preferably, the chemical composition of the glaze also includes 2-10% of loss on ignition and some trace components.

[0015] Another object of the present invention is to provide a simulated stone tile, comprising the vertical sculpture glaze of the present invention.

[0016] Preferably, the simulated stone tile comprises a body layer, a surface glaze layer, and a vertical sculpture glaze layer, and the vertical sculpture glaze layer comprises the vertical sculpture glaze described in the present invention.

[0017] Preferably, the surface glaze layer comprises the following chemical components in percentage by mass: Al2O3 22.56-26.12%, SiO2 56.14-62.51%, K2O 1.11-1.85%, Na2O 3.89-4.85%, CaO 0.32-1.88%, MgO 0.82-2.15%, ZrO2 4.86-7.5%, and the remainder is loss on ignition and some trace components.

[0018] Preferably, the surface glaze layer comprises the following raw materials in parts by weight: 6-12 parts of potassium feldspar, 8-15 parts of calcined kaolin, 30-40 parts of sodium feldspar, 5-15 parts of quartz, 8-15 parts of calcined alumina, 7-15 parts of zirconium silicate, 3-5 parts of burned talc, 1-5 parts of dolomite, and 8-12 parts of nepheline.

[0019] In order to cooperate with the sculptured glaze described in the present invention, when setting the surface glaze layer of the simulated stone tile, the introduction of zinc oxide can improve the compatibility of the glaze in the firing temperature range, and the compounding of calcined alumina and calcined kaolin can increase the initial melting temperature of the overall material, thereby avoiding the surface glaze layer from melting and closing too early during the firing process, thereby causing the gas to be discharged in time, thereby improving the density and fineness of the overall tile, and the product texture effect is better and the wear resistance is higher; in addition, zinc oxide can also increase the viscosity of the glaze after melting, so that the molten material can be filled into the gap in time after the exhaust on the surface of the material, thereby ultimately improving the product's anti-fouling effect, and there will be no situation where dirt and grime are hidden on the surface.

[0020] Preferably, the composition of the surface glaze layer also includes 2-10% loss on ignition and some trace components.

[0021] More preferably, the trace ingredients include zinc oxide and barium oxide.

[0022] Preferably, the simulated stone tile further comprises an inkjet printing layer arranged between the surface glaze layer and the vertical sculpture glaze layer.

[0023] By arranging an inkjet printing layer between the surface glaze layer and the vertical sculpture glaze layer on the simulated stone ceramic tile of the present invention, the simulated stone ceramic tile can utilize the principle of oily ink discharge during the firing process to make the formed simulated stone pattern clearer and more delicate, and even under specific patterns, it can present the unique spider web crack effect of natural stone, thereby significantly improving the ornamental value.

[0030] During the preparation process of the simulated stone ceramic tile described in the present invention, an inkjet printing layer is pre-printed on the surface glaze layer with a texture pattern, and a vertical sculpture glaze layer is arranged on the layer. In this way, the physical ink discharge effect can be utilized during the firing process of the product to make the pattern present an ideal peeling effect, so that the upper and lower layers, especially the vertical sculpture glaze layer, are fully integrated with the pattern, and the stone texture and three-dimensional effect of the product are guaranteed to meet the expectations while achieving wear resistance and easy cleaning performance.

[0115] Effect Example 1

[0116] In order to verify the various properties of the simulated stone tiles of the present invention, the tiles prepared in the embodiments and comparative examples were subjected to the following tests:

[0117] (1) Texture evaluation test: 10 testers were selected to evaluate the surface texture of the product using the printed pattern as the control. The score ranged from 1 to 10 (integer points). The clearer and more realistic the texture, the higher the score, while the rougher and less realistic the texture, the lower the score. The average score of each sample was calculated and recorded.

[0118] (2) Antifouling performance test: The antifouling grade test was conducted in accordance with GB / T 3810.14-2016. The test used green pollutant chrome green in light oil, red pollutant in light oil, iodine solution, and olive oil as pollutants. The lowest grade among the test results of each pollutant was used for statistics.

[0119] (3) Cleanability test: Use blue ink for anti-fouling test, purple-blue ink, blue and black oil-based markers to draw pictures and lines on the surface of the tile within a range of 100X100mm. Then leave it for 24 hours, wet it with a sponge and rinse it with tap water for 3 minutes, then wipe it with a towel to observe whether the traces left after wiping are obvious and how easy it is to wipe.

[0120] (4) Wear resistance test: According to GB / T 3810.14-2016 Part 7 Determination of surface wear resistance of glazed tiles, the test sample is 100×100 mm, and 8 different sample positions are sampled for each embodiment or comparative example, and the test results are comprehensively judged.

[0121] The test results are shown in Table 3.

[0122] Table 4

[0123]

[0124]

[0125] It can be seen from the results that the simulated stone tiles provided with a specific surface glaze layer and a vertical sculpture glaze layer according to the present invention have good comprehensive performance, not only the simulated stone texture is clear and realistic, such as Figure 1 As shown, when the product obtained in Example 1 is compared with the sampled marble material, there is almost no apparent difference, and the grain evaluation also reaches at least 8.5 points. This is mainly due to the introduction of zinc and strontium in the vertical carving glaze during the setting, and the adjustment of the calcium, magnesium and barium contents, so that the glaze layer after firing is transparent. After the inkjet printing layer is set, the surface glaze layer with specific ingredients can fully exhaust and promote interlayer bonding during firing, and the principle of oily ink discharge is used to make the grain effect clear and delicate; in addition, such a design can also effectively improve the wear resistance and anti-fouling effect of the product. The anti-fouling grade of the products in each embodiment under the national standard test is 5, and the wear resistance test results reach 6000 revolutions and 4, which can be fully applied to working environments such as kitchens and bathrooms that have extremely high requirements for wear resistance and anti-fouling. In addition, the product is also easy to clean, such as Figure 2 and3 As shown, after the product of Example 1 is painted, the stains can be completely removed by simply wiping with water, and the product is highly convenient to use.

[0126] In contrast, the products described in Comparative Examples 1 to 3 have improper selection of raw materials when setting the surface glaze layer, resulting in improper chemical composition of the products, which not only reduces the texture effect, but also has poor anti-fouling and wear resistance. In the products of Comparative Examples 4 to 10, due to improper setting of the vertical sculpture glaze layer, some products have a texture score of only 6 points or less, and the lowest anti-fouling level is only level 3, and the cleaning difficulty is also increased. Figure 4 As shown, the product of comparative example 5 still has certain traces after cleaning, and the wear resistance test result of the product is only level 3 at 1500 revolutions.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention.
