However, traditional ceramic tiles have some problems in use, such as easy staining, difficult cleaning, wet and slippery, and prone to safety accidents, which limit the application range and user experience of ceramic tiles.

At the same time, the substrate should have good temperature resistance, and can withstand the highest temperature in the sintering process, that is, not less than 650℃.

[0076] In the step S2, the surface of the ceramic tile is roughened by sandblasting or acid etching. When sandblasting, quartz sand is used as abrasive, and the pressure is controlled at 0.4-0.6MPa; when acid etching, dilute hydrochloric acid or sulfuric acid is used, the concentration is 5%-10%, and the treatment time is 5-10 minutes to form appropriate roughness and increase the adhesion of the coating to the substrate.

[0077] In the step S3, deionized water is used to clean the surface of the ceramic tile, and the water temperature is controlled at 20-30℃, and the cleaning time is not less than 5 minutes. In addition, ultrasonic cleaning equipment can be used to assist cleaning to ensure that the oil stains, dust and other impurities are completely removed.

[0078] In the step S4, the specific preparation method of the nano solution includes:

[0079] Mix deionized water and dispersant and stir evenly.

[0080] Gradually add nano-silicon dioxide, nano-zinc oxide, nano-titanium dioxide, polytetrafluoroethylene, nano-alumina, wear-resistant filler, and continue to stir.

[0081] Add organosilane modifier, ultraviolet absorber and antibacterial agent, and continue to stir to ensure uniform dispersion.

[0082] Finally, add silane coupling agent, stir well until a uniform and stable nano solution is formed.

[0083] In the step S5, when using the spraying method, the distance between the spray gun and the surface of the ceramic tile should be kept at 20-30cm, and the spraying pressure is 0.2-0.4MPa. When spin coating, the speed is controlled at 500-1000rpm, and the spin coating time is 30-60 seconds to ensure uniform coating of the nano solution on the surface of the ceramic tile.

[0084] In the step S6, the ceramic tile coated with the nano solution is placed in a drying oven, and the temperature is set at 80℃, and the drying time is 45 minutes. During the drying process, the air in the drying oven should be circulated to avoid local overheating.

[0085] In the step S7, the dried ceramic tile is placed in a sintering furnace, the sintering temperature is set at 500℃, and the sintering time is 20 minutes. The heating rate is controlled at 5-10℃ / min to ensure that the nano coating is tightly combined with the surface of the ceramic tile.

[0086] In the step S8, the sintered ceramic tile is subjected to performance detection, including adhesion test (using tape method, no falling off is qualified), wear resistance test (using wear tester, wear amount is less than 0.02 g / 1000 times is qualified) and slip resistance test (using friction coefficient tester, friction coefficient is greater than 0.5 is qualified).

[0090] In the present application, by preparing a nano coating on the surface of the ceramic tile, the stain resistance of the ceramic tile is significantly improved. The components such as silicon dioxide and zinc oxide in the nano coating can effectively reduce the adsorption of stains, so that the surface of the ceramic tile is easy to clean, and even after long-term use, it can still maintain a clean and new appearance. Secondly, the addition of nano alumina and wear-resistant fillers greatly enhances the wear resistance and scratch resistance of the coating, so that the ceramic tile can maintain good appearance and service life even after daily wear and tear.

The ceramic tile produced by the preparation method can meet the needs of the high-end market due to its excellent performance and aesthetic appearance, enhancing the market competitiveness of the product and bringing better economic benefits to the manufacturer.
