Hospitals, schools, toilets and the like have special requirements on skid resistance and antibiosis, so that the demand for the skid-resistant antibacterial ceramic tiles is large. The main strategy for preparing the anti-skid ceramic tile is to prepare a material containing a micro-nano structure on the surface of the ceramic tile, and when pressure is applied to the ceramic tile, air or water in the micro-nano structure is extruded out to form suction so as to achieve an anti-skid function. The principle of preparing the antibacterial ceramic is that nano materials with antibacterial function, such as silver oxide, zinc oxide, titanium oxide and the like, are added into ceramic glaze, and the materials have antibacterial performance or generate strong oxidizing free radicals capable of killing bacteria, fungi and viruses under the irradiation of light.
Chinese patent CN2760156Y discloses an improved structure of anti-skid ceramic tile or stone, which is characterized in that an anti-skid agent is smeared on the surface of the ceramic tile, micro-pores on the surface of the ceramic tile are utilized to form a capillary effect, thousands of 2-7 micron scale-level concave holes are manufactured, a vacuum chuck principle is applied, when the floor is wet and the ceramic tile is pressed, suction force is increased to achieve the anti-skid effect of the ceramic tile and stone, but the anti-skid agent is easy to be removed under long-time friction, and the durability is poor. Chinese patent CN201314109Y discloses an anti-skid luminous floor tile, which uses the concave-convex surface of ground glass to form an anti-skid layer to achieve the anti-skid purpose, but the anti-skid effect is poor under the condition of water. Although the method can achieve the aim of skid resistance, the anti-skid ceramic tiles are widely used in places such as hospitals, schools, toilets and the like, so that the anti-skid ceramic tiles have high requirements on antibacterial property, and the antibacterial property needs to be increased on the basis of skid resistance.
Chinese patent CN107355057A discloses an antibacterial and anti-slip ceramic tile, which is covered with an anti-slip layer and an antibacterial layer to achieve the anti-slip and antibacterial purposes, wherein the antibacterial layer is silver nitrate, which can achieve the antibacterial and anti-slip purpose, but needs to be baked twice, and the silver nitrate has high cost and is potentially harmful to human body. Other researches have been carried out by adding an antibacterial material into a ceramic glaze layer so as to achieve the aim of antibiosis, but the anti-skid property is poor.
Chinese patent CN 209694755U discloses a dish with antibacterial property, which comprises a dish body composed of a dish bottom and a dish edge, wherein the inner surface of the dish bottom and the inner surface of the dish edge are both coated with antibacterial layers, and the section of the dish body has the following multilayer structure: the ceramic substrate layer is attached to the ceramic substrate layer, the glaze layer is attached to the upper surface of the ceramic substrate layer, the antibacterial layer is attached to the outer surface of the glaze layer, the antibacterial layer is a nano zinc oxide antibacterial layer, in the section structure of the ceramic substrate layer, the particle size of zinc oxide particles is 15-65 nm, the inter-particle distance of the zinc oxide particles is 28-128 nm, and the sum of the section areas of all the zinc oxide particles accounts for 38-88% of the section area of the ceramic substrate layer; the glaze layer and the antibacterial layer are formed by sequentially coating enamel and an antibacterial agent on a ceramic substrate layer and sequentially forming a solid glaze layer and an antibacterial layer on the ceramic substrate layer through a preset sintering process. This patent enhances the antibacterial property by coating the antibacterial layer, but has a limited increase in antibacterial property and poor anti-slip property.
