Description

Technical Field

[0001] The invention belongs to the technical field of ceramic tiles and preparation thereof, in particular to a ceramic tile with anti-slip and high-efficiency anti-fouling properties and a preparation method thereof. Background Art

[0002] With the continuous development of the construction and decoration materials industry, ceramic tiles, as a common decorative material, have been widely used in home decoration, commercial spaces, public facilities and other fields. However, there are some problems with traditional ceramic tiles during use, such as easy stains, difficult to clean, slippery and prone to safety accidents, which limit the application scope and user experience of ceramic tiles. At present, ceramic tile products on the market mainly improve the anti-fouling performance by increasing the hardness of the glaze and improving the glaze formula.

[0003] However, these methods can only reduce the adsorption of stains to a certain extent, and it is still difficult to achieve the ideal cleaning effect for oily stains and stubborn stains. At the same time, in order to improve the anti-slip performance of tiles, the method of increasing the surface roughness is usually adopted, but this will affect the aesthetics and cleanliness of the tiles. The wear resistance and weather resistance of traditional tiles also need to be improved. During long-term use, the surface of tiles is prone to wear and scratches, which affects their appearance and service life. Especially in outdoor or public places, tiles must also have good UV resistance and environmental aging resistance. Summary of the invention

The components such as silicon dioxide and zinc oxide in the nano coating can effectively reduce the adsorption of stains, making the surface of the ceramic tile easy to clean and keeping it bright and clean even during long-term use. 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 still maintain a good appearance and service life when subjected to daily wear. In addition, the addition of organosilane modifiers and ultraviolet absorbers not only improves the water resistance and weather resistance of the coating, but also extends the service life of the coating and reduces the impact of environmental factors on the performance of the coating.

[0047] 2. In the present invention, the nano coating not only provides functional protection, but also can maintain the original color and texture of the tile, and can even increase a certain degree of gloss, making the surface of the tile more beautiful and improving the decorative effect. Due to the anti-fouling properties of the coating, the tile is not easily stained in daily use, and even if there are stains, it is easier to clean, which greatly reduces the amount of detergent used and the time of cleaning work, and reduces maintenance costs. The use of nano coating reduces the demand for chemical detergents, thereby reducing the burden on the environment. In addition, the materials and technologies used in the preparation process can be designed to have less impact on the environment, in line with the concept of sustainable development. Tiles with anti-slip properties provide better safety performance during use, especially when used in slippery environments such as kitchens and bathrooms, which can effectively reduce the occurrence of slip accidents and improve the user's sense of security and satisfaction. The tiles produced by this preparation method can meet the needs of the high-end market due to their excellent performance and aesthetics, enhance the market competitiveness of the products, and bring better economic benefits to manufacturers.
