[0002] In the development of ceramic art glazes, a variety of decorative glaze products have been developed in the field of glazes. The starburst patterns of crystalline glazes and the flowing colors of kiln-transformed glazes complement each other; the warm and lustrous pearl glazes and the iridescent colors of rainbow glazes complement each other; and the natural texture of flow glazes and the mysterious reactions of color-changing glazes each display their unique charm.

[0003] The glaze for honeycomb ceramic tiles, as disclosed in patent publication number CN 113402170A, is composed of a mixture of ceramic frit, kaolin, and pigments. The honeycomb ceramic tile includes a ceramic shell with a glaze adhered to its surface. Multiple honeycomb holes are distributed within the ceramic shell, forming honeycomb wall between adjacent holes. A rainproof edge is provided along the edge of the ceramic shell on the hole side, and the cross-section of the honeycomb holes along the rainproof edge has a concave-convex structure. Thermal insulation material and / or heat insulation material is also provided within the honeycomb holes. However, this technical solution clearly achieves the honeycomb effect through a ceramic shell with a honeycomb hole structure.

[0004] The oil-spot Tenmoku glaze of patent publication number CN 115259667A is composed of the following chemical components in parts by weight: 5-15 parts potassium feldspar, 3-13 parts sodium feldspar, 0.3-1.5 parts alumina, 0.3-1.5 parts cobalt oxide, 3-13 parts kaolin, 0.3-3 parts ox bone powder, 0.3-3 parts rice straw ash, 5-8 parts calcite, 2-4 parts dolomite, 1.3-2 parts zinc oxide, 25-30 parts quartz, 0.8-1 part talc, 10-13 parts wollastonite, 0.8-2 parts iron oxide red, 5-10 parts heavy calcium carbonate, 1-1.3 parts manganese carbonate, and 30-35 parts high-expansion frit.

[0021] The present invention is further illustrated by the following embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the present invention.

[0022] This invention innovatively proposes a three-dimensional effect glaze, a three-dimensional effect ceramic tile, and a method for preparing the same. The three-dimensional effect glaze exhibits a colorful three-dimensional honeycomb structure within the glaze layer. The following exemplarily illustrates the method for preparing the three-dimensional effect ceramic tile.

[0023] Preparation of ceramic green bodies. It should be understood that any ceramic green body suitable in the art can be used in this invention. The ceramic green body can be a conventional ceramic green body. As an example, the chemical composition of the ceramic green body may include, by mass percentage: SiO2 66%–70%, Al2O3 17%–20%, CaO 2%–4%, MgO 0%–5%, K2O 2%–6%, Na2O 1%–5%.

[0024] A honeycomb base glaze is applied to the surface of the blank. The mineral composition of the honeycomb base glaze includes, by mass percentage: 20%–30% quartz, 5%–10% kaolin, 12%–18% albite, 7%–15% calcite, 2%–7% wollastonite, 12%–17% calcined talc, 15%–25% calcined zinc oxide, 2%–6% titanium dioxide, 2%–4% glass powder, 1%–3% strontium carbonate, and 1%–5% dolomite.

[0025] Commonly used glass powder in the art can be used. The glass powder can be a SiO2-CaO-MgO-Na2O system glass powder. As an example, the chemical composition of the glass powder includes, by mass percentage: SiO2 68%–75%, CaO 6%–10%, MgO 2%–6%, Na2O 10%–15%. For example, the chemical composition of the glass powder includes, by mass percentage: SiO2 68%–75%, CaO 6%–8%, MgO 2%–4%, Na2O 10%–15%. In an embodiment, the chemical composition of the glass powder includes, by mass percentage: SiO2 75%, CaO 8%, MgO 4%, Na2O 13%.

[0026] In addition to the aforementioned mineral composition, the honeycomb base glaze can selectively incorporate 0-5% ceramic colorant by mass of the mineral composition. Various colorants commonly used in the art can be selected. These colorants include, but are not limited to, cobalt blue, iron oxide yellow, and praseodymium yellow. The introduction of colorant does not affect the formation of the honeycomb effect, but only affects the color of the honeycomb base glaze, thus enhancing its aesthetic appeal.

[0027] Preparation of the honeycomb base glaze slurry: Additives and water are added to the mineral composition (and colorant) of the honeycomb base glaze, ball-milled until homogeneous, and sieved to obtain the honeycomb base glaze slurry. The additives include sodium carboxymethyl cellulose and sodium tripolyphosphate. As an example, the mass content of sodium carboxymethyl cellulose is 0.1% to 0.5% of the honeycomb base glaze mineral composition, and the mass content of sodium tripolyphosphate is 0.3% to 1.0% of the honeycomb base glaze mineral composition. Water can be added to the honeycomb base glaze slurry during use to adjust to the desired final slurry specific gravity.

[0028] The honeycomb base glaze is applied by pouring or spraying. For example, the specific gravity of the honeycomb base glaze is 1.5–1.6 g / cm³. 3 The glaze application rate is 600-700 g / m². 2 By controlling the specific gravity and glaze application amount of the honeycomb base glaze within the above-mentioned range, a strong three-dimensional honeycomb effect and a smooth, defect-free glaze surface will be achieved. If the specific gravity and glaze application amount of the honeycomb base glaze are too low, the glaze will lack a three-dimensional honeycomb effect. If the specific gravity and glaze application amount of the honeycomb base glaze are too high, air bubbles in the glaze layer will be difficult to expel, easily resulting in glaze bubble defects.

[0029] In some embodiments, the chemical composition of the honeycomb base glaze includes, by mass percentage: 42%–58% SiO2, 4%–7% Al2O3, 1.5%–3% K2O + Na2O, 12%–15% CaO, 5%–7% MgO, 15%–25% ZnO, 1%–2% SrO, and 2%–5% TiO2.

[0030] A honeycomb effect glaze is applied to the surface of the body after the honeycomb base glaze is applied. The mineral composition of the honeycomb effect glaze includes, by mass percentage: 5%–15% quartz, 5%–10% kaolin, 40%–55% albite, 2%–6% barium feldspar, 2%–10% calcined talc, 7%–15% calcined zinc oxide, 1%–4% red mud, and 3%–5% coal gangue. Among them, red mud and coal gangue are industrial solid waste.

[0031] Red mud commonly used in the art can be used. It should be understood that any red mud that causes the chemical composition of the honeycomb effect glaze to fall within the specified range is suitable for this invention. As an example, the chemical composition of the red mud includes, by mass percentage: 20%–25% SiO2, 5%–9% Al2O3, 3%–7% Na2O, 40%–50% CaO, 2%–7% TiO2, and 8%–13% Fe2O3. In an embodiment, the chemical composition of the red mud includes, by mass percentage: 25% SiO2, 7% Al2O3, 5% Na2O, 46% CaO, 7% TiO2, and 10% Fe2O3.

[0032] Coal gangue commonly used in the art can be used. It should be understood that any coal gangue that causes the chemical composition of the honeycomb effect glaze to fall within the specified range is suitable for this invention. As an example, the chemical composition of the coal gangue includes, by mass percentage: SiO2 55%–65%, Al2O3 16%–25%, Na2O 3%–7%, CaO+MgO 1%–5%, K2O+Na2O 1%–4%, TiO2 1%–4%, Fe2O3 2%–8%. In an embodiment, the chemical composition of the coal gangue includes, by mass percentage: SiO2 58%, Al2O3 23%, Na2O 6%, CaO+MgO 3%, K2O+Na2O 2%, TiO2 3%, Fe2O3 5%.

[0033] A glaze slurry for preparing a honeycomb effect glaze is prepared by adding additives and water to the mineral composition of the honeycomb effect glaze, ball milling until homogeneous, and sieving to obtain the glaze slurry. The additives include sodium carboxymethyl cellulose and sodium tripolyphosphate. As an example, the mass content of sodium carboxymethyl cellulose is 0.1%–0.5% of the mineral composition of the honeycomb effect glaze, and the mass content of sodium tripolyphosphate is 0.3%–1.0% of the mineral composition. Water can be added to the glaze slurry to adjust it to the desired final glaze slurry specific gravity before use.

[0034] The honeycomb effect glaze is applied by spraying or pouring. For example, the specific gravity of the honeycomb effect glaze is 1.4–1.5 g / cm³. 3 The glaze application rate is 700-800 g / m². 2 By controlling the specific gravity and glaze application amount of the honeycomb effect glaze within the above-mentioned range, a strong three-dimensional honeycomb effect and a smooth, defect-free glaze surface will be achieved. If the specific gravity and glaze application amount of the honeycomb effect glaze are too low, the glaze will lack a three-dimensional honeycomb effect. If the specific gravity and glaze application amount of the honeycomb effect glaze are too high, the honeycomb effect will be poor, the base glaze color will not be visible, and air bubbles in the glaze layer will be difficult to expel, easily resulting in glaze bubble defects.

[0035] In some embodiments, the chemical composition of the honeycomb effect glaze includes, by mass percentage: 61%–68% SiO2, 10%–15% Al2O3, 5%–7% K2O + Na2O, 1%–8% CaO, 2.5%–6.5% MgO, 1%–5% ZnO, 1%–6% BaO, and 5%–14% Fe2O3.

[0036] The body after applying the honeycomb glaze is fired. As an example, the firing temperature is 1150–1220°C, and the firing time is 35–70 minutes.

[0037] If the honeycomb effect glaze is omitted, that is, the honeycomb base glaze is applied directly to the surface of the body and then fired, the honeycomb effect will not be present, and the brick surface will only show a white skin-like crystalline glaze effect.

[0038] If the honeycomb base glaze is omitted, meaning the honeycomb effect glaze is applied directly to the surface of the brick before firing, the brick surface will not exhibit a three-dimensional honeycomb effect. Furthermore, if the amount of honeycomb effect glaze applied is too low, the brick surface will not only lack a honeycomb effect but will also appear as a glossy blackish-brown glaze; if the amount of honeycomb effect glaze applied is too high, the brick surface will only exhibit the effect of an oil-spot glaze with a blackish-brown base and gold spots.

[0039] Polishing can be performed after firing. Of course, a polishing process can also be omitted.

[0040] In summary, the three-dimensional effect glaze of this invention is the first of its kind in the market. The three-dimensional effect ceramic tile glaze of this invention has a smooth, flawless surface that can be polished, and the internal three-dimensional effect of the glaze layer is extremely strong. The three-dimensional effect glaze of this invention can be applied to architectural ceramics, daily-use ceramics, and art ceramics. Furthermore, the honeycomb effect glaze of this invention incorporates industrial solid waste red mud and coal gangue, improving the utilization rate of solid waste.

It should also be understood that the following examples are only for further explanation of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0047] Table 1. Composition of 3D Effect Glaze Raw Materials in Each Embodiment

[0048] Table 2. Composition of raw materials for 3D effect glazes in each comparative example.

[0049] The following analysis and explanation are based on the above embodiments, comparative examples, and test results:

[0050] 1. Analysis of the experimental results of Examples 1-5 shows that the three-dimensional effect ceramic tiles prepared in Examples 1-5 have a better honeycomb effect. The principle of three-dimensional effect glaze is to utilize small bubbles to form large bubbles, and the rising of these bubbles disturbs the high-temperature glaze melt, bringing the base glaze to the surface of the glaze layer. The voids caused by the rising base glaze are filled by the effect glaze, ultimately forming a three-dimensional honeycomb structure. The red mud in the honeycomb effect glaze contains ferric oxide, which will transfer to magnetite during high-temperature firing. The mixed oxides of ferric oxide and magnetite in the honeycomb effect glaze surround the base glaze in a honeycomb pattern, while the base glaze is concentrated in the middle of the honeycomb and directly penetrates to the surface. Because the interior of the honeycomb structure has less contact with oxygen, it is mainly composed of magnetite and appears black overall; that is, the bottom of the honeycomb structure is mainly composed of magnetite, and the bottom of the honeycomb effect appears black due to the accumulation of magnetite. The surface of the honeycomb structure has more contact with oxygen, and magnetite oxidizes at high temperature to form ferric oxide, so the surface is mainly composed of ferric oxide. The surface of the honeycomb structure is mainly composed of ferric oxide, and is reddish-brown overall. Zinc silicate crystals formed by the base glaze pushed to the surface are adsorbed onto the edges of the honeycomb structure. These crystals, coated with ferric oxide, appear golden, giving the honeycomb structure a golden sheen. The interior of the honeycomb structure is entirely black, the outer surface is reddish-brown, the surface outline is golden, and the inner core is the color of the base glaze. Specifically, because cobalt blue pigment was added to the base glaze in Example 1, the center of the honeycomb exhibits the blue color of the base glaze itself. Figures 1-2 ).

[0051] 2. Compared with the examples, the honeycomb base glaze of Comparative Example 1 has a quartz content lower than the specified range and an albite content higher than the specified range; the honeycomb effect glaze has a quartz content higher than the specified range, while the albite and calcined talc content are lower than the specified range. This results in a lower firing temperature for the base glaze and a higher firing temperature for the effect glaze. Poor venting during firing leads to numerous glaze bubble defects on the glaze surface.

[0052] 3. Compared with the examples, the quartz content of the honeycomb base glaze in Comparative Example 2 is higher than the specified range, while the albite and calcined talc content is lower than the specified range; the calcite and calcined talc content of the honeycomb effect glaze is higher than the specified range. This results in a higher viscosity of the base glaze slurry, a higher firing temperature, and poor high-temperature fluidity, which fails to disturb the high-temperature glaze melt, resulting in a lack of honeycomb effect in the glaze layer; while the effect glaze has a low high-temperature viscosity, is over-fired, and has many open bubbles on the glaze surface.

[0053] 4. Compared with the examples, the calcite and strontium carbonate content of the honeycomb base glaze in Comparative Example 3 was lower than the specified range; the red mud content of the honeycomb effect glaze was lower than the specified range, while the coal gangue content was higher than the specified range. This resulted in a higher firing temperature for the base glaze, which could not disturb the high-temperature glaze melt and thus could not form a honeycomb effect. The lower red mud content and higher coal gangue content in the effect glaze introduced fewer iron metal oxides and the higher viscosity of the glaze melt, further hindering the formation of the honeycomb effect. As a result, the glaze surface had no honeycomb effect and presented an overall brownish-red glossy effect.

[0054] 5. Compared with the examples, the honeycomb base glaze of Comparative Example 4 had higher contents of calcite, strontium carbonate, and dolomite than specified ranges; the honeycomb effect glaze had higher contents of red mud than specified ranges. This resulted in a larger loss on ignition of the base glaze and more bubbles. In contrast, the honeycomb effect glaze contained more ferric oxide, causing a large number of small bubbles to coalesce into large bubbles, which then broke through the glaze surface to form an oil droplet effect. However, the base glaze was overfired, resulting in excessively large bubbles that could not close, ultimately forming large open bubbles.

[0055] 6. Compared with the examples, the honeycomb base glaze of Comparative Example 5 had higher contents of calcined zinc oxide and titanium dioxide than the specified range; the honeycomb effect glaze had higher contents of calcined zinc oxide and barium feldspar than the specified range. Since titanium dioxide and barium oxide can promote phase separation and crystallization in the glaze, and the barium feldspar content in the honeycomb effect glaze is too high, it interacts with the titanium dioxide in the base glaze, ultimately resulting in an overall oil-spot glaze effect.

[0056] 7. Comparative Example 6 is basically the same as Example 1, except that the glazing process of honeycomb base glaze and honeycomb effect glaze is changed.

[0057] The results showed that the glaze layer exhibited a blue and brown phase-separated base color, with a crystalline effect of gold and white intermingling, but the glaze surface lacked a three-dimensional honeycomb effect. Figure 3 ).
