Background
The ceramic tile is firing the in-process because the remaining gas pocket of adobe or glaze and tiny crackle therefore can adsorb the pollutant, present super clean and bright ceramic tile adopts silica sol nano-material to do antifouling coating, at the polished tile promptly, throw glazed tile boundary surface and form the one deck and have the thin layer of filling the pore, special safeguard function has, and stable in structure's nanometer protective layer, mainly used promotes ceramic polished tile's antifouling performance, be known as the revolutionary breakthrough of the antifouling technique of ceramic industry, the glossiness on brick surface has also been strengthened greatly simultaneously. With the improvement of living standard of people, light pollution stimulates eyes. In recent years, ink-jet pattern-penetrated matt bricks and full-polished glaze soft bricks are valued by people.
In order to prevent external pollution in the prior art, an organic silicon antifouling agent is used, and under a specific condition, silanol groups and organic silicon molecular groups on the surface of a ceramic product treated by the organic silicon antifouling agent undergo a condensation dehydration reaction, so that organic silicon molecular bonds are connected to the surface of the ceramic product and are tightly combined together to form an organic siloxane hydrophobic film, and the hydrophobic film is in an oriented arrangement structure.
In addition, chinese patent CN107858097A provides a super-hydrophobic fluorosilicone resin ceramic antifouling agent, which is a normal temperature cured super-hydrophobic fluorosilicone resin generated by using perfluoro hydrogen-containing polymethylhydrosiloxane as a matrix resin, amino-substituted cage polysilsesquioxane and polyisocyanate as a cross-linking catalyst, and nano alumina as a reinforcing filler. The concrete formula comprises the following components in percentage by mass: 15.0 to 20.0 percent of perfluoro hydrogen-containing polymethylhydrosiloxane, 3.0 to 6.0 percent of amino substituted cage polysilsesquioxane, 1.0 to 2.0 percent of polyisocyanate, 3.0 to 6.0 percent of nano alumina, 4.0 to 8.0 percent of polyhydroxy polysiloxane, 1.0 to 3.0 percent of boric acid derivative and 60.0 to 72.0 percent of diluent. The invention has the following advantages: (1) the main component of the antifouling agent is fluorosilicone resin with excellent hydrophobicity and good antifouling effect; (2) the cage-type polysilsesquioxane and polyisocyanate substituted by amino with eight functionalities are used as a crosslinking catalyst for the first time, and are synthesized by adopting a twice dripping process, so that the antifouling agent is higher in crosslinking density and uniform in crosslinking; (3) the nano alumina is used as a filler, and the boric acid derivative is used for chemical modification, so that the antifouling agent has higher hardness and better filling property; (4) the antifouling agent has small influence on the glossiness of the ceramic, and the experiment tests show that the glossiness change of the ceramic is less than 3 degrees on the premise of ensuring the antifouling effect.
However, the common organic silicon anti-fouling agent and the anti-fouling agent adopted by the anti-fouling agent are common single anti-fouling agents, and in view of incomplete anti-fouling of the anti-fouling agents in the same industry, in the actual situation, vinegar, soy sauce, coffee and blue ink are mixed together, and the stain cannot be wiped cleanly by adopting the anti-fouling agent. In addition, the black caulking agent and cement powder are mixed by water and coated on the surface of the ceramic tile, then the surface of the ceramic tile is continuously trodden, and the caulking agent and the cement powder are trodden and scraped by a heel rotating ring, so that the caulking agent cannot be treated, pollutants are easily left in pores of the ceramic tile, and the surface of the ceramic tile has small particle black points like pinholes. Cannot be cleaned by all cleaning agents on the market.
