Technical Field
The invention relates to the technical field of ceramic tiles, in particular to a formula and a production process of an ultra-stain-resistant ceramic tile.

As a further improvement of the present technical solution, the coagent includes a silane coupling agent, nano alumina, and hydroxyapatite.
As a further improvement of the technical scheme, the weight ratio of the silane coupling agent, the nano alumina and the hydroxyapatite in the active auxiliary agent is 3:1:1.
As a further improvement of the technical scheme, the auxiliary materials comprise titanium dioxide, aluminum powder, diatomite and nano zirconia.
In another aspect, the invention provides a process for producing the super soil resistant tile formulation as defined in any one of the above, comprising the steps of:
s1, placing high-quality kaolin and high-purity silica sand into a mixer, and uniformly stirring;
s2, adding kaolin and active auxiliary agent into the mixer, and continuously stirring and mixing to obtain a mixture;
s3, gradually adding auxiliary materials into the mixture until a uniform formula is formed;
s4, grinding and screening the mixture to obtain fine powder, and putting the powder into a forming machine to form a ceramic tile blank;
s5, performing primary sintering on the ceramic tile blank to make the ceramic tile blank hard; before or during sintering, the surface of the ceramic tile is treated by spraying high-pressure water flow or using an acid solution to form a micro concave-convex structure;
s6, performing secondary sintering to enable the ceramic tile blank to become a final super-stain-resistant ceramic tile; and coating a layer of pollution-resistant protective layer on the surface of the sintered ceramic tile.
Preferably, in the step S6, the coating agent is uniformly coated on the surface of the tile by spraying or rolling; and curing and drying the coating agent to form the pollution-resistant protective layer.
Preferably, the coating agent includes 90 parts by weight of ethyl acetate, 5 parts by weight of epoxy resin, 5 parts by weight of silane coupling agent, and 3 parts by weight of polyurethane resin.
Compared with the prior art, the invention has the beneficial effects that:
1. in the formula and the production process of the super-stain-resistant ceramic tile, materials such as high-quality kaolin, high-purity silica sand and the like are subjected to optimized proportion, and a special treatment process is combined, so that a microscopic concave-convex structure and a stain-resistant protective layer are formed on the surface of the ceramic tile; the special structure and the protective layer effectively prevent the attachment of stains, so that the ceramic tile has excellent stain resistance, can be easily cleaned, and keeps long-term attractive appearance; the surface of the ceramic tile is coated with a special coating agent to form a pollution-resistant protective layer; the coating agent can still maintain the original brightness and color of the ceramic tile after long-time use, and is not easy to fade, turn yellow or damage, thereby maintaining the long-term beautiful degree of the ceramic tile.
2. In the formula and the production process of the super stain-resistant ceramic tile, compared with the traditional process, the formula and the production process of the super stain-resistant ceramic tile are simpler and more convenient, and are easy to implement and control; the optimization of the formula and the introduction of the special treatment process enable the ceramic tile preparation process to be more efficient and stable, and greatly improve the production efficiency and the stability of the product quality. The simple preparation process has important significance for large-scale production and industrial production, and can reduce cost and promote competitiveness.
3. In the formula and the production process of the super-stain-resistant ceramic tile, the super-stain-resistant performance of the ceramic tile is realized by constructing a micro concave-convex structure and a stain-resistant protective layer; in addition, the application of the coating agent further enhances the aesthetic degree and durability of the ceramic tile; the innovative technical scheme has uniqueness in solving the problem of pollution resistance of the ceramic tile, and brings new development opportunities for the ceramic tile industry.
