Description

Technical Field

[0001] This invention relates to the field of ceramic technology, specifically to a three-dimensional glaze, a simulated stone ceramic tile, and its preparation method. Background Technology

[0002] Currently, in the ceramic tile industry, soft-polished simulated stone tiles are popular due to their warm surface texture and soft glaze. These products are generally made by setting a surface glaze with a gloss of around 30° and supplementing it with fiber modules, or by post-polishing and waxing. However, these simulated stone tiles cannot achieve the delicate texture of traditional simulated stone tiles and have the drawbacks of being not scratch-resistant or stain-resistant, making them unsuitable for use in environments such as kitchens and bathrooms where scratches or dirt can easily accumulate. Summary of the Invention

[0003] Based on the shortcomings of existing technologies, the purpose of this invention is to provide a three-dimensional glaze. This product, based on its special chemical composition, has an ideal three-dimensional sculpted effect when applied to the preparation of simulated stone ceramic tiles. The texture is delicate and the stone simulation is high. At the same time, the product has high wear resistance, surface stains can be easily removed, and the anti-fouling effect is good.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A sculptural glaze 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%, Na2O 3.59–5.85%, CaO 6.32–8.28%, MgO 3.82–5.65%, SrO 3.16–5.45%, BaO 1.12–2.36%, ZnO 3.86–5.45%, with the balance being loss on ignition and trace components.

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

[0008] 20-35 parts of sodium feldspar, 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 sculpted frit, 5-15 parts of washed clay, 5-10 parts of calcined talc, and 3-7 parts of wollastonite.

[0009] Preferably, the sculpted ingot comprises the following chemical composition by mass percentage: 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%, and BaO 8.19–10.54%.

[0010] The sculptural glaze of this invention introduces zinc oxide and strontium oxide as specific components to improve light transmittance and crystal texture, while controlling the relative content of silicon dioxide. This effectively enhances the clarity of the surface texture and the color effect. Furthermore, due to the high content of magnesium oxide, calcium oxide, and barium oxide, the overall formula has a good solvent effect when applied to the firing and preparation of ceramic tiles, resulting in a glaze with higher transparency, better wear resistance, and stain resistance after polishing.

[0011] When selecting raw materials to prepare sculptural glaze, strontium carbonate is used as a sintering flux to lower the overall firing temperature of the material and optimize the high-temperature fluidity of the formula. Combined with a zinc source, this improves the smoothness and fineness of the overall glaze surface. On the other hand, the calcium and magnesium content in the raw materials is set at a high level, which allows these two elements to form calcium magnesium feldspar crystal phases during sintering, further improving the fluidity and reactivity of the material under high-temperature conditions. In addition, the three types of frits can form microcrystals during sintering, ensuring that the glaze surface has thermoplasticity during firing and reducing problems such as pores and air venting, ultimately achieving a three-dimensional sculptural effect and significantly improving the anti-fouling effect.

[0012] Preferably, the calcium-containing fused ingot comprises the following chemical components by mass percentage: 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%, with the balance being loss on ignition and trace components.

[0013] Preferably, the magnesium-containing molten metal comprises the following chemical composition by mass percentage: 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%, with the balance being loss on ignition and trace components.

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

[0015] Another object of the present invention is to provide a simulated stone ceramic tile, including the sculpted glaze described in the present invention.

[0016] Preferably, the simulated stone ceramic tile includes a body layer, a surface glaze layer, and a relief glaze layer, wherein the relief glaze layer includes the relief glaze described in this invention.

[0017] Preferably, the surface glaze layer comprises the following chemical components by mass percentage: 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%, with the balance being loss on ignition and trace components.

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

[0019] To complement the sculpted glaze described in this invention, the introduction of zinc oxide into the surface glaze layer of the simulated stone ceramic tile can improve the compatibility of the glaze's firing temperature range. The combination of calcined alumina and calcined kaolin increases the initial melting temperature of the overall material, preventing the surface glaze layer from melting and sealing prematurely during firing, thus preventing gas from being released in time. This improves the overall density and fineness of the ceramic tile, resulting in better texture and higher wear resistance. In addition, zinc oxide can also increase the viscosity of the glaze after melting, allowing the molten material to fill the gaps in time after venting on the material surface, ultimately improving the product's stain resistance and preventing dirt and grime from accumulating on the surface.

[0020] Preferably, the composition of the glaze layer also includes 2-10% sintering agent and some trace components.

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

[0022] Preferably, the simulated stone ceramic tile further includes an inkjet printing layer disposed between the surface glaze layer and the relief glaze layer.

[0023] The simulated stone ceramic tile of this invention has an inkjet printing layer set between the surface glaze layer and the embossed glaze layer. This allows the simulated stone ceramic tile to have clearer and more delicate simulated stone patterns during the firing process by using the principle of oil-based ink removal. Under certain patterns, it can even present the spider web crack effect unique to natural stone, significantly improving its aesthetic appeal.

[0024] Another object of the present invention is to provide a method for preparing the simulated stone ceramic tile, comprising the following steps:

[0025] Set the blank layer;

[0026] Set a top glaze layer;

[0027] Print textured patterns on the glaze layer and set up an inkjet printing layer;

[0028] A relief glaze layer is applied to the inkjet printing layer to obtain a rough blank;

[0029] The rough blank is fired and then polished to obtain the simulated stone ceramic tile.

[0030] In the preparation process of the simulated stone ceramic tile of the present invention, an inkjet printing layer is set on the surface glaze layer to print the effect texture pattern, and a three-dimensional glaze layer is set on this layer. In this way, the physical ink removal effect can be used during the product firing process to make the pattern present an ideal peeling effect, so that the upper and lower layers, especially the three-dimensional glaze layer, are fully integrated with the pattern. Under the premise of achieving wear resistance and easy cleaning performance, the stone texture and three-dimensional effect of the product are guaranteed to meet expectations.

[0031] Preferably, the preform layer comprises the following raw materials in parts by weight:

[0032] Potassium sodium sand 20-35 parts, ball soil 15-25 parts, kaolin 10-15 parts, bentonite 5-10 parts, talc 4-10 parts, potassium sodium water abrasive 15-25 parts, pyrophyllite 3-5 parts, diopside 2-5 parts.

[0033] The preparation method of the green body layer is as follows: After ball milling and sieving of the raw materials, the powder particles are conveyed to a press and pressed into green bodies. The green bodies are then dried in a drying kiln at 140–160°C for 40–60 minutes. After exiting the drying kiln, the green bodies are sprayed with 20–30 g / m³ of [unspecified substance]. 2 The water is then used to obtain the blank layer.

[0034] Preferably, the surface glaze layer is applied by applying a surface glaze slurry;

[0035] More preferably, the method for preparing the surface glaze slurry is as follows:

[0036] The raw materials for preparing each glaze layer are mixed, then water is added, the mixture is ball-milled, and sieved to obtain the glaze slurry.

[0037] More preferably, the surface glaze slurry has a specific gravity of 1.88 to 1.92 g / mL and a water content of 28 to 32%.

[0038] More preferably, the amount of glaze applied to the surface glaze layer is 400-500 g / m². 2 .

[0039] Preferably, the relief glaze layer is applied by applying relief glaze slurry;

[0040] More preferably, the method for preparing the sculpted glaze paste is as follows:

[0041] The raw materials for preparing each sculpted glaze are mixed, then water is added and the mixture is ball-milled and sieved to obtain an intermediate slurry with a specific gravity of 1.45-1.52 g / mL. Methyl water is then added and mixed to obtain the sculpted glaze slurry.

[0042] The mass ratio of the intermediate slurry to methyl water is (0.5-1.5):100.

[0043] More preferably, the glaze application amount of the three-dimensional sculpted glaze layer is 400-500 g / m². 2 .

[0044] Preferably, the inkjet printing layer is achieved by printing pattern ink with a grayscale of 5-50%.

[0045] Preferably, the firing temperature is 1100-1200℃ and the firing time is 50-80 minutes.

[0046] The beneficial effects of this invention are that it provides a three-dimensional sculpted glaze, which, based on its special chemical composition, has an ideal three-dimensional sculpted effect when applied to the preparation of simulated stone ceramic tiles, with delicate texture and high stone simulation; at the same time, the product has high wear resistance, surface stains can be easily removed, and it has good anti-fouling effect.

[0115] Example 1

[0116] To verify the various performance characteristics of the simulated stone ceramic tile described in this invention, the ceramic tiles prepared in each embodiment and comparative example were subjected to the following tests:

[0117] (1) Texture evaluation test: Select 10 testers to score the surface texture of the product using the printed pattern as a reference. The score ranges from 1 to 10 points (integer score). The clearer and more realistic the texture, the higher the score. The rougher and less realistic the texture, the lower the score. The average score of each sample is calculated and recorded.

[0118] (2) Antifouling performance test: The antifouling level test was conducted according to GB / T 3810.14-2016. The green staining agent chrome green, the red staining agent in light oil, iodine solution and olive oil were used as staining agents. The lowest level among the test results of each staining agent was used for statistical analysis.

[0119] (3) Cleanliness test: Blue and purple ink and blue and black oil-based markers were used to draw on a 100x100mm area of ​​the tile surface. The tile was then left to stand for 24 hours. After rinsing with tap water using a sponge for 3 minutes, the tile was wiped with a towel. The results were observed to see if the marks left after wiping were obvious and how easy it was to wipe.

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

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

[0122] Table 4

[0123]

[0124]

[0125] The results show that the simulated stone ceramic tile with a specific surface glaze layer and a three-dimensional glaze layer described in this invention has excellent comprehensive performance. Not only are the simulated stone textures clear, realistic, and three-dimensional, but... Figure 1 As shown, comparing the product obtained in Example 1 with the sampled marble, there was almost no difference in appearance. The texture evaluation also reached at least 8.5 points. This is mainly attributed to the introduction of zinc and strontium into the sculpted glaze during its application, along with the controlled calcium, magnesium, and barium content, resulting in a transparent glaze layer after firing. Furthermore, the addition of an inkjet printing layer, combined with a specific glaze composition, allows for thorough air removal and promotes interlayer bonding during firing. The oil-based ink removal principle results in a clear and delicate texture. In addition, this design effectively improves the product's wear resistance and stain resistance. All products in the examples achieved a stain resistance level of 5 under national standard testing, and the wear resistance test result reached level 4 after 6000 revolutions, making them suitable for use in kitchens, bathrooms, and other work environments with extremely high requirements for wear resistance and stain resistance. Moreover, the product is also easy to clean, such as… Figure 2 and3 As shown, after being painted, the product in Example 1 can be completely removed by simply wiping with water, making it highly convenient to use.

[0126] In contrast, the products described in Comparative Examples 1-3 had improper selection of raw materials in the application of the glaze layer, resulting in an inappropriate chemical composition. This not only reduced the texture effect but also led to poor stain resistance and abrasion resistance. Furthermore, the products in Comparative Examples 4-10 suffered from improper application of the sculpted glaze layer, with some products scoring only 6 points or below in texture and achieving a minimum stain resistance level of 3. Additionally, the products became more difficult to clean. Figure 4 As shown, Comparative Example 5 still showed some marks after cleaning, and the product's abrasion resistance test result was only level 3 at 1500 revolutions.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
