Description

Technical Field

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

[0002] Glaze is an indispensable part of the ceramic production process. Glaze gives ceramics color, texture and gloss. The application classification of ceramics mainly includes containers, art exhibits and tiles. For tiles, glaze not only gives the tile glaze color, texture and gloss, but also determines the hardness and stability of the tile glaze layer.

[0003] Marble tiles are a popular type of tile, often used for background wall decoration. With the improvement of living standards, the previous imitation of marble texture effects only through screen printing and inkjet can no longer meet higher demands. Some people add microcrystalline frits to the glaze to make the glaze layer of the tile closer to the texture and gloss of marble.

[0004] However, the existing microcrystalline marble tiles have poor internal bonding strength of the glaze layer, resulting in the problem of poor overall stability of the glaze layer, which affects the environmental applicability and durability of the tiles. Summary of the invention

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

[0006] In the first aspect, the present application provides a jade ice marble tile adopting the following technical solution: A jade ice marble tile, comprising a green body, a base glaze layer, an ink layer, a frit layer and a protective glaze layer arranged in sequence, wherein the base glaze layer is prepared by base glaze, the frit layer is prepared by frit, and the protective glaze layer is prepared by protective glaze; The frit includes a first frit, which is prepared by raw materials including the following weight percentages: 50-55% silicon dioxide; 16-19% aluminum oxide; 2-3.8% sodium oxide; 4-6.2% potassium oxide; 1.2-2.6% magnesium oxide; 4-6% calcium carbonate; 4.9-6.8% strontium carbonate; and 7.5-9.5% zinc oxide. The protective glaze comprises the following raw materials in weight percentage: 60-64% silicon dioxide; 2.5-4.5% sodium oxide; 1.5-3% potassium oxide; 3-5% magnesium oxide; 7-9% aluminum oxide; 11-13.5% barium carbonate; 1-3% calcium carbonate; and 5-7% zinc oxide.

[0007] By adopting the above technical scheme, the raw material composition of the protective glaze makes the texture of the tile surface close to the effect of the natural marble pickling surface, and the crystallization effect of the protective glaze layer is delicate and soft, thus presenting a natural patina, and combined with the frit layer, the color of the tile surface is balanced, the surface gloss is warmer and thicker, and the color is close to the original jade.

[0008] In the past, ceramics with texture effects similar to the above could only be achieved on small-sized art ceramic exhibits. If the glaze layer area is increased, the stability of the glaze layer will deteriorate, so it is difficult to apply to large-sized ceramic tile products. However, through the combination of the first frit composed of the above raw materials and the protective glaze, 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 world has sufficient thermal stability to resist the impact of changes in the external environment, thereby improving the stability and durability of the glaze layer.

[0009] In addition, while ensuring the matching of expansion coefficients, the first frit has a high aluminum oxide content, so the tile surface has higher hardness and wear resistance. The raw material composition of the protective glaze ensures that the raw materials can be melted while reducing the amount of calcium carbonate, thereby improving the tile surface's resistance to acid and alkali corrosion.

[0010] Optionally, the frit includes a first frit and a second frit configured in a weight ratio of (1.5-4):1; The second frit is prepared by raw materials comprising the following weight percentages: Silicon dioxide 56-60%; aluminum oxide 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%.

[0011] By adopting the above technical solution, the first frit and the second frit together form a frit layer, which improves the expansion coefficient matching between the frit layer and the protective glaze layer, and at the same time improves the density of the frit layer structural skeleton, thereby further improving the surface hardness and wear resistance of the tile.

[0012] Optionally, the base glaze is prepared from the following raw materials in the following weight percentages: Silicon dioxide 78-85%; sodium oxide 0.3-2%; potassium oxide 10-14%; aluminum oxide 2-5%; calcium carbonate 1-3.5%.

[0013] 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 range of base glaze options is wider and the bonding stability between the body and the glaze layer can be ensured.

[0014] Optionally, the frit has a fineness of 60 to 120 meshes.

[0015] 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.

[0016] In the second aspect, the present application provides a method for preparing a raw jade ice marble tile using the following technical solution: A method for preparing a raw jade ice marble tile, comprising the following steps: The protective glaze is added with water to prepare a protective glaze slurry; Add water to the base glaze to make base glaze slurry; Applying base glaze slurry on the surface of the green body to form a base glaze layer; forming an ink layer on the surface of the base glaze layer; Distributing frit on the surface of the base glaze layer to form a frit layer; applying a cellulose aqueous solution to the surface of the frit layer to form irregular cracks; Applying protective glaze slurry on the surface of the frit layer to form a protective glaze layer; It is fired at high temperature and the surface is soft-polished after firing to make marble tiles.

[0017] By adopting the above technical scheme, the base glaze layer, ink layer, frit layer and protective glaze layer are formed step by step, wherein a cellulose aqueous solution is applied to shrink the surface of the frit layer to form irregular cracks, and then the protective glaze layer is covered to protect the cracks, thereby visually simulating the ice texture of the patina and tactilely ensuring the smooth touch of the tile surface.

[0018] Optionally, the high temperature sintering temperature is 1120-1200° C., and the high temperature sintering time is 40-60 min.

[0019] By adopting the above technical scheme, since the composition of the frit layer and the protective glaze layer are properly matched, the temperature range of high-temperature firing is relaxed, the bonding stability between the frit layer and the protective glaze layer can be ensured, and the overall glaze layer can have higher hardness and wear resistance.

[0020] Optionally, the specific gravity of the protective glaze slurry is 1.2 to 1.5 g / cm 3 The glaze amount of the protective glaze slurry is 250-400 g / m 2 The specific gravity of the base glaze slurry is 1.7 to 2.1 g / cm 3 The glaze amount of the base glaze slurry is 580-750g / m 2 .

[0021] Optionally, the amount of the frit is 1800-2300 g / m 2 .

[0022] By adopting the above technical solution, the above glazing amount and material distribution amount are helpful to improve the overall stability of the glaze layer.

[0023] Optionally, the method for preparing the frit comprises the following steps: The raw materials of the frit are mixed, melted at 1500-1550° C., the molten system is uniformly cooled, and crushed to a fineness of 60-120 meshes to obtain a frit.

[0024] Optionally, the cellulose aqueous solution is prepared by mixing sodium carboxymethyl cellulose and water, and the specific gravity of the cellulose aqueous solution is 0.8-1.3 g / cm 3 The amount of cellulose aqueous solution applied is 70 to 95 g / m 2 .

[0025] By adopting the above technical solution, the above cellulose aqueous solution can form irregular cracks on the surface of the frit layer and maintain the stability of the frit layer.

[0026] Optionally, the brightness of the semi-finished product after firing is 45 to 50 degrees, and the brightness of the finished product after surface soft polishing is 47 to 53 degrees.

[0027] Optionally, the protective glaze and the base glaze both have a 325-mesh sieve residue of 0.3%.

[0028] In summary, this application has the following beneficial effects: 1. The raw material composition of the protective glaze of the present application makes the surface texture of the 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, and the frit layer makes the surface color of the tile balanced, the surface brightness is more warm and thick, and the color is close to the original jade. And through the combination of the first frit composed of the above raw materials and the protective glaze, 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 world has sufficient thermal stability, thereby improving the stability and durability of the glaze layer.

[0029] 2. The present application may also choose to form a frit layer with the first frit and the second frit together, thereby improving the expansion coefficient matching between the frit layer and the protective glaze layer, and at the same time improving the density of the frit layer structural skeleton, thereby further improving the surface hardness and wear resistance of the tile.

[0081] Product performance testing The original jade ice-grain marble tiles prepared in Examples 1-6 and Comparative Examples 1-4 were used as test samples and the following tests were performed.

[0082] Evaluation of glaze performance: Sales and R&D personnel in the ceramic field were assembled into an evaluation team to conduct a comprehensive evaluation of the glaze texture, gloss, color and touch. The evaluation results are shown in Table 1.

[0083] Table 1 Thermal stability test: The marble tile sample was placed in an oven at 180°C for 1 hour, then the marble tile sample was taken out and immediately placed in water at 25°C for cooling. The above heating and cooling steps were repeated three times, and finally the surface of the glaze layer was observed for any tangible cracks. The test results are shown in Table 2.

[0084] Hardness test: Referring to JCT 908-2013 "Artificial Stone", the surface Mohs hardness of the marble tile sample was tested. The test results are shown in Table 2.
