Problems solved by technology

However, it is difficult to evenly distribute the wide surface area inside the porous ceramic tiles in this way, and when a part of the antibacterial substances gather together to block the internal pores of the porous ceramic tiles, there will be a side effect of reducing the moisture absorption and resistance, so it is difficult to Applicable to porous tiles that contain a large number of fine pores and have moisture absorption and...

Embodiment

[0069] The mixture described in the following Table 1 was pulverized by a ball mill, and the obtained slurry was spray-dried to obtain uniformly mixed spherical particle powder with a moisture content of 8% and an average particle size of 300 μm.

[0070] Next, the above-mentioned granular powder was subjected to dry press molding to manufacture porous ceramic tiles with a length, height, and thickness of 7 cm, 7 cm, and 0.6 cm, respectively. Next, after drying the above porous ceramic tiles in a continuous drying furnace at 250°C, glass frit powder and pigment with an average particle size of 15um and a refractoriness of 750°C were dispersed in water and glazed by spraying.

[0071] Finally, the glazed porous ceramic tiles were put into a continuous gas furnace (RHK) and thermally decomposed at a temperature of 850° C. for 10 minutes to produce porous ceramics with an average diameter of pores of 5 nm and a porosity of 45%. brick.

experiment example

[0077] Experimental example: pH measurement of porous ceramic tiles

[0078] The porous ceramic tiles of the above examples and comparative examples were soaked in 25° C. water (100 ml) for 10 minutes. Thereafter, ions are present in the pores included in the porous pores as time passes. At this time, the pH was measured by measuring the acidity (pH) with a pH meter, and the results are shown in Table 2 below.

Abstract

A porous ceramic tile comprising γ-alumina and an antibacterial active material is provided. Provided is a method for preparing a porous ceramic tile, comprising the steps of: forming a ceramic molded product by mixing γ-alumina and an antibacterial active material; preparing a porous ceramic tile by dry press molding the ceramic molded product; drying the molded porous ceramic tile; applying a glaze to the dried porous ceramic tile; and thermally decomposing and firing the glaze-applied porous ceramic tile.

Description

technical field [0001] The invention relates to an antibacterial porous ceramic brick and a manufacturing method thereof. Background technique [0002] Existing antibacterial tiles are generally formed by mixing antibacterial substances with water to prepare a suspension and then applying it to the surface of the tile or mixing a glaze and then applying it to the surface. However, it is difficult to evenly distribute the wide surface area inside the porous ceramic tiles in this way, and when a part of the antibacterial substances gather together to block the internal pores of the porous ceramic tiles, there will be a side effect of reducing the moisture absorption and resistance, so it is difficult to It is suitable for porous tiles that contain a large number of fine pores and have moisture absorption and waterproof properties. [0003] In addition, when using a simple coating method, there is a concern that the antibacterial substance will be detached from the surface of ...
