Description

Technical Field

[0001] The present application relates to the field of ceramics, and particularly to a raw jade ice pattern marble tile and a preparation method thereof. Background Art

[0002] Glaze is an indispensable part in the process of ceramic production. Glaze endows ceramics with color, texture and luster. In the application classification of ceramics, it mainly includes containers, art exhibits and tiles. For tiles, glaze can not only endow the tile surface with color, texture and luster, but also determine the hardness and stability of the tile glaze layer.

[0003] Marble tiles are a widely favored type of tiles and are commonly used for background wall decoration. With the improvement of living standards, the previous methods of only imitating marble texture effects through screen printing and inkjet printing can no longer meet higher requirements. Some people add microcrystalline frit to the glaze to make the glaze layer of the tile closer to the texture and luster of marble.

[0004] However, due to the poor internal bonding force of the glaze layer in the existing microcrystalline marble tiles, the overall stability of the glaze layer fails to meet the standard, which affects the environmental adaptability and durability of the tiles. Summary of the Invention

[0005] In order to obtain a glaze layer with good marble effect while improving the thermal stability of the glaze layer, the present application provides a raw jade ice pattern marble tile and a preparation method thereof.

[0006] In the first aspect, a raw jade ice pattern marble tile provided by the present application adopts the following technical solution:

[0007] A raw jade ice pattern marble tile includes a body, a base glaze layer, an ink layer, a frit layer and a protective glaze layer arranged in sequence. The base glaze layer is prepared from base glaze, the frit layer is prepared from frit, and the protective glaze layer is prepared from protective glaze;

[0008] The frit includes a first frit, and the first frit is prepared from raw materials including the following weight percentages: 50-55% of silicon dioxide; 16-19% of aluminum oxide; 2-3.8% of sodium oxide; 4-6.2% of potassium oxide; 1.2-2.6% of magnesium oxide; 4-6% of calcium carbonate; 4.9-6.8% of strontium carbonate; 7.5-9.5% of zinc oxide;

[0009] The protective glaze includes raw materials with the following weight percentages: 60-64% of silicon dioxide; 2.5-4.5% of sodium oxide; 1.5-3% of potassium oxide; 3-5% of magnesium oxide; 7-9% of aluminum oxide; 11-13.5% of barium carbonate; 1-3% of calcium carbonate; 5-7% of zinc oxide.

[0010] By adopting the above technical solution, the raw material composition of the protective glaze is combined to make the texture of the tile surface close to the effect of the acid-washed surface of natural marble, and the crystallization effect of the protective glaze layer is delicate and soft, thus presenting a natural patina feeling. Combined with the frit layer, the tile surface has a balanced color development, and the surface gloss is more warm and thick, and the color is close to the original jade.

[0011] Ceramics with a texture effect similar to the above could only be achieved on small-sized art ceramic exhibits in the past. If the area of the glaze layer is increased, the stability of the glaze layer becomes poor, so it is difficult to be applied to large-sized tile products. Through the combination of the first frit and the protective glaze with the above raw material composition, while presenting an ideal texture, the expansion coefficients of the frit layer and the protective glaze layer match, reducing the stress concentration of the overall glaze layer after firing, so as to ensure that the part of the overall glaze layer close to the outside has sufficient thermal stability to resist the influence caused by changes in the external environment, thereby improving the stability and durability of the glaze layer.

[0012] In addition, while ensuring the matching of the expansion coefficients, the first frit has a high alumina content, so the tile surface has high hardness and wear resistance. The raw material composition of the protective glaze is combined to reduce the dosage of calcium carbonate while ensuring that the raw materials can be melted, thereby improving the acid and alkali corrosion resistance of the tile surface.

[0013] Optionally, the frit includes the first frit and the second frit configured according to a weight ratio of (1.5 - 4):1;

[0014] The second frit is prepared from raw materials including the following weight percentages:

[0015] Silica 56 - 60%; Alumina 6.5 - 8%; Sodium oxide 0.3 - 0.8%; Potassium oxide 7 - 8.5%; Calcium carbonate 12 - 13%; Barium carbonate 2.5 - 3.8%; Zinc oxide 10 - 12%.

[0016] By adopting the above technical solution, the first frit and the second frit together form a frit layer, improving the matching degree of the expansion coefficients of the frit layer and the protective glaze layer, and at the same time increasing the density of the structural framework of the frit layer, thereby further improving the surface hardness and wear resistance of the tile.

[0017] Optionally, the base glaze is prepared from raw materials including the following weight percentages:

[0018] Silica 78 - 85%; Sodium oxide 0.3 - 2%; Potassium oxide 10 - 14%; Alumina 2 - 5%; Calcium carbonate 1 - 3.5%.

[0019] By adopting the above technical solution, since the composition of the frit layer and the composition of the protective glaze layer are properly combined, the range of options for the base glaze is relatively wide, and the bonding stability between the green body and the glaze layer can also be ensured.

[0020] Optionally, the fineness of the frit is 60-120 mesh.

[0021] By adopting the above technical solution, the above fineness of the frit helps to form a stable frit layer and better combine with the protective glaze layer.

[0022] In a second aspect, a preparation method of the original jade ice pattern marble tile provided by the present application adopts the following technical solution: A preparation method of an original jade ice pattern marble tile includes the following steps:

[0023] The protective glaze is added with water to form a protective glaze slurry;

[0024] The base glaze is added with water to form a base glaze slurry;

[0025] The base glaze slurry is applied to the surface of the green body to form a base glaze layer;

[0026] An ink layer is formed on the surface of the base glaze layer;

[0027] The frit is spread on the surface of the base glaze layer to form a frit layer;

[0028] A cellulose aqueous solution is applied to the surface of the frit layer to form irregular cracks;

[0029] The protective glaze slurry is applied to the surface of the frit layer to form a protective glaze layer;

[0030] High-temperature firing is carried out, and after the firing is completed, surface soft polishing treatment is carried out to make the marble tile.

[0031] By adopting the above technical solution, the base glaze layer, the ink layer, the frit layer and the protective glaze layer are formed step by step. Among them, the application of the cellulose aqueous solution causes the surface of the frit layer to shrink, forming irregular cracks, and then covering the protective glaze layer to protect the cracks, so as to visually simulate the texture of the patinated ice pattern and ensure the smooth touch of the tile surface tactilely.

[0032] Optionally, the temperature of the high-temperature firing is 1120-1200 °C, and the time of the high-temperature firing is 40-60 min.

[0033] By adopting the above technical solution, since the composition of the frit layer and the composition of the protective glaze layer are properly matched, the temperature range of the high-temperature firing is broadened, and the bonding stability of the frit layer and the protective glaze layer can be ensured, and the overall glaze layer can be ensured to have high hardness and wear resistance characteristics.

[0034] Optionally, the specific gravity of the protective glaze slurry is 1.2-1.5 g / cm 3 , and the glaze application amount of the protective glaze slurry is 250-400 g / m 2 ; the specific gravity of the base glaze slurry is 1.7-2.1 g / cm 3, the application amount of the base glaze slurry is 580-750 g / m 2 .

[0035] Optionally, the cloth amount of the frit is 1800-2300 g / m 2 .

[0036] By adopting the above technical solution, the above application amount of glaze and cloth amount contribute to improving the overall stability of the glaze layer.

[0037] Optionally, the preparation method of the frit includes the following steps:

[0038] Mix the raw materials of the frit, melt at 1500-1550 °C, cool after the melting system is uniform, and pulverize to a fineness of 60-120 mesh to obtain the frit.

[0039] Optionally, the aqueous cellulose solution is prepared from sodium carboxymethyl cellulose and water, and the specific gravity of the aqueous cellulose solution is 0.8-1.3 g / cm 3 , and the application amount of the aqueous cellulose solution is 70-95 g / m 2 .

[0040] By adopting the above technical solution, the above aqueous cellulose solution can not only form irregular cracks on the surface of the frit layer, but also maintain the stability of the frit layer.

[0041] Optionally, the luminosity of the semi-finished product after firing is 45-50 degrees, and the luminosity of the finished product after surface soft polishing is 47-53 degrees.

[0042] Optionally, both the protective glaze and the base glaze have a sieve residue of 0.3% through a 325-mesh sieve.

[0043] In summary, the present application has the following beneficial effects:

[0044] 1. The combination of the raw material components of the protective glaze in the present application makes the surface texture of the ceramic tile close to the effect of the acid-washed surface of natural marble, and the crystallization effect of the protective glaze layer is delicate and soft, thus presenting a natural patina feeling. Combined with the frit layer, the surface color of the ceramic tile is balanced, the surface luminosity is more warm and thick, and the color is close to the original jade. And through the combination of the first frit and the protective glaze with the above raw material components, while presenting an ideal texture, the expansion coefficients of the frit layer and the protective glaze layer are matched, reducing the stress concentration of the overall glaze layer after firing, so as to ensure that the part of the overall glaze layer close to the outside has sufficient thermal stability, thereby improving the stability and durability of the glaze layer.

[0045] 2. The present application can also choose to form the frit layer jointly by the first frit and the second frit, improving the matching degree of the expansion coefficients of the frit layer and the protective glaze layer, and at the same time improving the density of the structural framework of the frit layer, thereby further improving the surface hardness and wear resistance of the ceramic tile. Brief Description of the Drawings

[0046] Figure 1 It is a photo of the original jade ice pattern marble tile in Embodiment 1 of the present application. Detailed Description of the Invention

[0047] The following further describes the present application in conjunction with the Figure 1 drawings for a more detailed explanation.

[0048] Generally, the glaze layer of microcrystalline marble tiles will mix frit and surface glaze together and apply them on the surface of the ink layer for firing to improve the hardness and wear resistance of the glaze layer. However, this cannot meet the requirements of having an ice pattern texture and jade transparency visually, and being smooth to the touch without feeling cracks.

[0049] Therefore, in the present application, a frit layer and a protective glaze layer are successively formed on the tile to balance the requirements visually and tactilely. And to overcome the thermal stability problem caused by the delamination of the frit and the protective glaze, the raw material compositions of the frit and the protective glaze are specifically formulated to match the expansion coefficients of the frit layer and the protective glaze layer, ensuring the overall stability of the glaze layer.

[0126] Product performance testing

[0127] Using the original jade ice pattern marble tiles prepared in Examples 1 - 6 and Comparative Examples 1 - 4 as test samples, the following tests are carried out.

[0128] Glaze layer performance evaluation: A evaluation group is formed by gathering salespersons and R & D personnel in the ceramic field, and evaluations are made comprehensively in terms of glaze layer texture, gloss, color and touch, etc. The evaluation results are shown in Table 1.

[0130]

[0131]

[0132] Thermal stability test: Place the marble tile test sample in an oven at 180 °C for 1 h, then take out the marble tile test sample and immediately put it into water at 25 °C to cool. Repeat the above heating and cooling steps three times, and finally observe whether visible cracks appear on the glaze layer surface. The test results are shown in Table 2.

[0133] Hardness test: Refer to JCT 908 - 2013 "Artificial Stone" to test the surface Mohs hardness of the marble tile test sample. The test results are shown in Table 2.

[0134] Abrasion resistance test: Refer to GB / T 3810.7 - 2016 "Test methods for ceramic tiles - Part 7: Determination of abrasion resistance of glazed tiles surface".

[0136]

[0137]

[0138] As shown in Table 1, the marble tiles obtained in Examples 1-6 all showed excellent performance in terms of texture, gloss, color and touch, achieving the effect characteristics of the original jade ice pattern. In addition, according to the feedback from industry veterans, Example 1 is the closest to the texture of the acid-washed surface of natural marble, which can be referred to Figure 1 , and the color development of Example 6 has the thickest feeling.

[0139] As shown in Table 2, the marble tiles obtained in Examples 1-3 showed good thermal stability, high hardness and high wear resistance, proving that the marble tiles have good durability. Compared with Comparative Examples 1-4, the marble tiles of Example 1 had the best comprehensive performance in terms of durability, especially being able to pass the thermal stability test three times continuously. Therefore, it is proved that the specific formulation of the frit and the raw material composition of the protective glaze make the frit layer and the protective glaze layer combine stably, thus balancing the appearance performance and the actual application quality of the glaze layer at the same time.

[0140] Compared with Example 1, the wear resistance of Examples 4-6 was further improved, proving that the first frit and the second frit together improve the density of the structure framework of the frit layer, thereby improving the wear resistance characteristics.

[0141] In addition, the marble tile samples of Examples 1-6 also had good acid and alkali resistance capabilities, and could be placed in a sodium carbonate solution with a pH of 9 and a citric acid solution with a pH of 3 for up to 168 hours respectively without any change on the surface of the glaze layer, further proving good durability.

[0142] The marble tiles prepared in Examples 1-6 could reach a size of 1800×900 mm, and the glaze layer of the tiles showed good durability performance. Therefore, large-scale batch production of tiles with the original jade ice pattern effect was realized.
