Antifouling self-cleaning ceramic structure

-A kind of anti-fouling self-cleaning ceramic structure technical field

[0001] The present utility model relates to construction and decoration material structures, in particular to an improved ceramic structure.

Background technique

[0002] Ceramics refer to all artificial industrial products that use clay and other inorganic non-metallic minerals as raw materials. It includes various products made from clay or a mixture containing clay through kneading, shaping, and calcining. From the roughest earthenware to the finest fine pottery and porcelain belong to its scope. The main raw material for it is silicate minerals (such as clay, quartz, etc.) derived from nature, so it is used in industries such as glass, cement, enamel, and refractory materials. Ceramic materials are mostly oxides, nitrides, borides and carbides. Therefore, as a construction and decoration material, ceramics are widely used in construction, indoor and outdoor decoration, kitchen and bathroom sanitary ware and household daily life. However, in the process of use, after a period of time, the surface of ceramics is often polluted to varying degrees, which may accumulate dust, stained with sewage, dirt, or kitchen oil, etc., which often requires a lot of manpower to clean ceramic utensils or ceramic tiles. surface. The contaminated ceramic face not only affects the beauty, but also easily breeds bacteria and viruses, pollutes the environment, and affects people's physical and mental health and living environment.

Utility model content

[0003] Therefore, in view of the above problems, the present invention proposes a modified ceramic structure, which is a ceramic structure with anti-fouling and self-cleaning functions developed by the combination of nanotechnology and traditional ceramic technology.

[0004] The technical solution of the utility model is:

[0005] The anti-fouling self-cleaning ceramic structure of the present invention is: a glaze layer (20) is covered on a ceramic substrate (10), and the outer surface of the glaze layer (20) is chemically etched rough On the surface (201), a composite nano-material film layer (30) is deposited on the rough surface (201) of the glaze layer (20), and the outer surface (301) of the composite nano-material film layer (30) It is a smooth surface.

[0006] Further, the roughness Ra of the rough surface (201) of the glaze layer (20) is 100 μm-500 μm_o

[0007] The utility model adopts the above technical scheme and uses the combination of nanotechnology and traditional ceramic technology to develop a ceramic structure with anti-fouling and self-cleaning functions, which solves the problem that existing ceramics are easy to accumulate dust, stains and bacteria The shortcomings of the virus.

Description of the drawings

[0008] FIG. 1 is a cross-sectional view of an existing ceramic;

[0009] FIG. 2 is a cross-sectional view of a ceramic glaze layer after chemical etching;

[0010] FIG. 3 is a cross-sectional view of the utility model.

Detailed ways

[0011] The present utility model will now be further described with reference to the drawings and specific implementations.

[0012] Referring to FIG. 1, the existing ceramic is a ceramic substrate 10 covered with a glaze layer 20, and the glaze layer 20 is generally relatively smooth, but its microscopic view is also an uneven surface, so Ordinary ceramics are easily stained with dust and dirt

Stains.

[0013] Referring to FIG. 2, the outer surface of the glaze layer 20 is chemically etched into a rough surface 201. Preferably, the roughness Ra of the etched rough surface 201 of the glaze layer 20 is 100 μm-500 μm. Generally, chemical etching of the glaze layer in the prior art can be used, which will not be repeated here.

[0014] Referring to FIG. 3, a composite nano-material film layer 30 is deposited on the rough surface 201 of the glaze layer 20, and the outer surface 301 of the composite nano-material film layer 30 is a smooth surface. The composite nanomaterial film layer 30 can be attached to the glaze layer 20 by spraying, dipping, smearing, centrifugation or pressing, and the outer surface of the composite nanomaterial film layer 30 can be polished as much as possible smooth.

[0015] The anti-fouling and self-cleaning ceramic structure of the present invention is etched on the glaze layer 20 to form a rough surface, which is more conducive to the adhesion of the composite nano-material film layer 30, and because the composite nano-material film layer 30 has a relatively smooth microstructure The surface is therefore not easy to be stained with dust, stains, and bacteria and viruses, and has anti-fouling and self-cleaning effects. It can be widely used in construction, indoor and outdoor decoration, kitchen and bathroom sanitary ware and household daily life.

[0016] Although the present utility model is specifically shown and introduced in combination with the preferred embodiments, those skilled in the art should understand that, within the spirit and scope of the present utility model defined by the appended claims, the form and the Various changes can be made to the present utility model in details, which are all within the protection scope of the present utility model.
