[0002] With the continuous development of the building decoration materials market, consumers have higher and higher requirements for the decorative effect and texture of tiles. In particular, imitation marble tiles are widely popular because of their beauty and stability of natural marble. However, traditional imitation marble tiles can only imitate the color of marble, but it is difficult to achieve the unique natural texture and texture of marble, which limits its application in the high-end decoration market.

[0003] However, how to form complex and natural textures on the surface of tiles has always been a major technical challenge in the industry. Existing technologies usually use engraving, printing or special glaze formulas to try to achieve texture effects, but these methods either have high production costs or the texture effects are not natural enough and are difficult to mass produce.

The mixed raw materials should have a consistent color and particle size distribution.

[0056] In step S3, the press needs to be set to an appropriate pressure, usually between 2000 and 5000 tons, to obtain a tile body of the desired thickness and shape. During the pressing process, it is necessary to ensure that the pressure is evenly distributed to avoid cracks or deformation of the body.

[0057] In step S4, the drying temperature is set between 100°C and 200°C, and the drying time is adjusted according to the thickness and humidity of the green body, usually 4-8 hours. The drying process needs to be carried out slowly to prevent the green body from cracking due to too fast evaporation of water.

[0067] Aging: Set the mixed texture agent aside and let it age for 24 hours to ensure that all ingredients are fully incorporated.

[0068] In step S7, during the glazing process, the thickness of the glaze layer should be controlled, usually 0.5-1.5 mm. The glaze should evenly cover the surface of the tile body without glaze leakage or glaze accumulation.

[0069] In step S8, the firing temperature is set between 1100℃ and 1300℃, which is adjusted according to the characteristics of the glaze and the body.

[0089] In step S2, the mixing process is usually carried out at a low speed for about 20-30 minutes until all the raw materials are evenly distributed and the colorant is completely integrated into the ceramic powder. The mixed raw materials should have a consistent color and particle size distribution.

[0090] In step S3, the press needs to be set to an appropriate pressure, usually between 2000 and 5000 tons, to obtain a tile body of the desired thickness and shape. During the pressing process, it is necessary to ensure that the pressure is evenly distributed to avoid cracks or deformation of the body. The pressed body needs to have a uniform thickness and density to facilitate subsequent drying and firing.

[0091] In step S4, the drying temperature is set between 100°C and 200°C, and the drying time is adjusted according to the thickness and humidity of the green body, usually 4-8 hours. The drying process needs to be carried out slowly to prevent the green body from cracking due to too fast evaporation of water. The moisture content of the green body after drying should be reduced to less than 2% to ensure the mechanical strength and stability of the green body.

[0092] In step S5, the crocodile skin texture glaze formula includes: 35-50 parts by weight of zirconium silicate, 25-30 parts by weight of kaolin, 15-20 parts by weight of feldspar, 7-10 parts by weight of quartz, 6-10 parts by weight of colorant, 4-10 parts by weight of texture agent, 3-5 parts by weight of rare earth oxide, 3-5 parts by weight of barium carbonate, 2-5 parts by weight of talc and 2-5 parts by weight of plasticizer.

[0097] Adding the metal oxide: Pass the premixed dry materials through a screen (e.g., 80 mesh) to remove larger particles. Add the iron oxide (or other metal oxide) to the screened dry materials. Mix again using a low speed agitator until the metal oxide is evenly distributed.

[0098] Prepare organic polymer solution: In another container, mix polyvinyl alcohol (PVA) and deionized water in proportion (e.g. 5% PVA dissolved in 95% water). Heat to 60-80°C and stir until PVA is completely dissolved.

[0099] Mixing wet materials: Slowly add the organic polymer solution to the dry material mixture. Use a medium speed agitator to mix until all ingredients are evenly combined to form a slurry with a certain viscosity.

[0100] Adjust Viscosity: If the viscosity of the texture agent is too high or too low, add more water or dry ingredients to adjust. Make sure the final texture agent has the proper flow and viscosity for easy application.

[0101] Aging: Set the mixed texture agent aside and let it age for 24 hours to ensure that all ingredients are fully incorporated.

[0102] In step S7, during the glazing process, the thickness of the glaze layer should be controlled, usually 0.5-1.5 mm. The glaze should evenly cover the surface of the tile body without glaze leakage or glaze accumulation.

[0103] In step S8, the firing temperature is set between 1100℃ and 1300℃, which is adjusted according to the characteristics of the glaze and the body. The firing cycle is usually 8-12 hours, and the temperature in the kiln must be uniform to obtain consistent tile quality. During the firing process, the glaze reacts chemically with the body to form a hard tile.

After edging is completed, a polishing machine is used for surface polishing. The speed of the polishing machine is set at 1500-2000 revolutions per minute, and the pressure of the polishing head on the tile surface is maintained at 0.2-0.4 MPa. Such polishing parameters can improve the flatness and glossiness of the tile, while avoiding over-polishing and protecting the crocodile leather texture from being damaged.

[0105] In step S11, the dimensional tolerance of the tiles should be controlled within ±0.5 mm to ensure the accuracy of the tiles.

The clarity and consistency of the texture are visually inspected, and the texture is required to have no obvious discontinuity or blur. The gloss is measured using a glossmeter, and the gloss is required to be between 60-90 degrees. The rejection rate of unqualified products should be controlled below 1%. After cleaning and drying, the tiles are packaged with foam or cartons with a thickness of 2-3 mm to ensure shock resistance and moisture resistance during transportation and storage. When packaging, the number of tiles per box depends on the size of the tiles. For example, 600x600 mm tiles are packed with 18-20 pieces per box.

[0106] In the present invention, the texture agent can form an irregular texture similar to crocodile skin on the surface of the tile, which is impossible to achieve with a simple glaze, and provides a unique visual effect for the tile. By adding the texture agent, the imitation marble tile not only imitates the color of marble, but also replicates its natural texture, greatly enhancing the decorativeness and aesthetics of the tile, and meeting the consumer's demand for high-end decorative materials. The texture agent makes the texture on the surface of the tile closer to the texture of real crocodile skin, improves the simulation of the product, and makes the imitation marble tile more attractive in the market. Tiles with special textures can often be sold at a higher price.
