All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
At present, the anti-slip ceramic tile is mainly characterized in that an anti-slip agent and a corrosive agent are sprayed or smeared on the surface of a finished ceramic tile, and the friction coefficient is improved by utilizing the anti-slip agent attached to the surface of a tile body; or the sintered brick body is manufactured into a macroscopic or microscopic rugged structure on the surface by adopting the modes of frit dry particles, special materials, a rugged mold, high Wen Yinhua glaze and the like, and the skidproof effect is achieved by utilizing the structure and the mechanical biting action and the vacuum adsorption action of the sole under pressure. The adoption of the frit dry particle material is a common method in the current anti-skid field of ceramic tile production, but is easy to cause dead angles for pollution and bacterial growth. Therefore, how to provide ceramic tiles with excellent antibacterial performance while achieving anti-slip is a key issue of concern in the field of architectural ceramics.
In view of the above, the invention provides an anti-slip antibacterial dry particle brick and a preparation method thereof.
On one hand, the embodiment of the invention provides an anti-skid antibacterial dry grain brick, which comprises a brick blank, and a ground glaze layer, an ink-jet layer and a dry grain glaze layer which are sequentially arranged on the surface of the brick blank from bottom to top; wherein the dry grain glaze layer comprises dry grains, and the dry grains comprise a micropore structure and silver oxide loaded in the micropore structure.
According to the technical scheme, the dry grain glaze layer is adopted to realize skid resistance of the ceramic tile, and meanwhile, silver oxide loaded in the micropore structure of the dry grains enables the dry grain glaze layer at the uppermost layer of the ceramic tile to have antibacterial and bacteriostatic properties, so that the ceramic tile is endowed with excellent antibacterial properties while the ceramic tile has skid resistance.

Performance testing
Antibacterial rate measurements were performed for examples 1 to 5 and comparative example 1, and the test results are shown in Table 1.
Antibacterial rate measurement: the antibacterial rate was determined according to the test method of JC/T897-2014 antibacterial ceramic product antibacterial Property.
TABLE 1
As can be seen from the results of Table 1, the present invention example used silver oxide supported in the dry particle micropores and had relatively high antibacterial activity against both Escherichia coli and Staphylococcus aureus, whereas the dry particle of comparative example 1 was not immersed in an aqueous solution containing silver ions, calcined, etc., and the silver oxide was not supported in the dry particle micropores and had poor antibacterial activity against both Escherichia coli and Staphylococcus aureus.
As can be seen from the results of examples 1 to 6, the antibacterial efficiency of example 1 against both E.coli and Staphylococcus aureus was better than that of example 4, and analysis revealed that the content of bismuth oxide in example 4 had an effect on the microporous structure of the dry particles, and that the content of bismuth oxide was too low and the microporous structure was small, thereby affecting the silver oxide loading. In example 6, after the dry particle precursor is soaked, ultrasound is not performed, so that the load of silver oxide is affected, and compared with example 6, the antibacterial rate of example 1 on escherichia coli and staphylococcus aureus is better, and the ultrasound can better enable the aqueous solution containing silver ions to enter micropores of the dry particles, so that the load of silver oxide is improved.
The foregoing is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention, but various modifications and variations will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
