Abstract

The utility model discloses a self-cleaning ceramic tile, which comprises a ceramic tile body and a micro-nano structure layer formed on the surface of the ceramic tile body; the super-hydrophobic and self-cleaning functions of the ceramic tile are realized through the micro-nano structure on the surface of the ceramic tile. The micro-nano structure on the surface of the ceramic tile enables a large amount of air to be stored between the concave and convex parts of the micro-nano structure, so that the stain can only contact with the mastoid surface of the micro-nano structure, the contact area of the stain and the surface of the ceramic tile is obviously reduced, the interface of the stain and the air is expanded, the stain cannot automatically expand, especially the water bead type stain can keep the spherical shape, and the super-hydrophobic and self-cleaning functions are realized. Especially when the floor tile is used as an exterior wall tile, the stain can automatically roll off and take away certain dust, or the stain and the dust can be easily taken away under the washing of rainwater, and when the floor tile is used as an interior floor tile, the stain can not be spread and is also easily cleaned, so that the floor is not polluted.

Description

Self-cleaning ceramic tile

Technical Field

The utility model relates to a ceramic tile, concretely relates to automatically cleaning ceramic tile.

Background

As is known to all, the surface of a ceramic tile is easy to be worn out due to inevitable friction and even impact during the use of the ceramic tile, the ceramic tile without the cover glaze layer loses smoothness, and the cleaning is still dirty even after the cleaning, and the main reason is that other substances such as dust and the like enter the interior of the ceramic tile through the ceramic tile without the cover glaze layer, so that the cleaning cannot be carried out, and the condition is easy to occur on the white ceramic tile. And the ceramic tile is not antifouling, the tiny holes formed by the overglaze layer can be filled with tiny particles, so that the surface of the ceramic tile is not clean, and the foreign matters filled in the holes cannot be cleaned. Especially for some exterior wall tiles, China needs to invest huge manpower, material resources and financial resources every year, and the high-altitude operation on buildings seriously threatens the personal safety of cleaning personnel, so that the self-cleaning tiles are urgently needed to be developed.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a self-cleaning ceramic tile makes the ceramic tile have super hydrophobic and self-cleaning function.

The utility model discloses a self-cleaning ceramic tile, which comprises a ceramic tile body and a micro-nano structure layer formed on the surface of the ceramic tile body;

further, the micro-nano structure layer comprises an epoxy resin layer formed on the surface of the ceramic tile body and a micron-sized mastoid structure formed on the epoxy resin layer;

further, the material of the micron-sized mastoid structure is a low-surface-energy material;

further, the diameter of the nano-columns is 500-800nm, and the distance between the nano-columns is 500-700 nm;

further, the low surface energy material is fumed silica;

further, the epoxy resin layer is formed by spraying;

further, the fumed silica is sprayed on the epoxy resin layer to form a micron-sized mastoid structure.

The utility model has the advantages that: the utility model discloses a self-cleaning ceramic tile through the structure of receiving a little on ceramic tile surface, realizes its super hydrophobic and self-cleaning function. The micro-nano structure on the surface of the ceramic tile enables a large amount of air to be stored between the concave and convex parts of the micro-nano structure, so that the stain can only contact with the mastoid surface of the micro-nano structure, the contact area of the stain and the surface of the ceramic tile is obviously reduced, the interface of the stain and the air is expanded, the stain cannot automatically expand, especially the water bead type stain can keep the spherical shape, and the super-hydrophobic and self-cleaning functions are realized. The tested self-cleaning ceramic tile has a surface contact angle larger than 150 degrees and a rolling angle smaller than 10 degrees, so that the self-cleaning ceramic tile has an excellent self-cleaning function. Especially when the floor tile is used as an exterior wall tile, the stain can automatically roll off and take away certain dust, or the stain and the dust can be easily taken away under the washing of rainwater, and when the floor tile is used as an interior floor tile, the stain can not be spread and is also easily cleaned, so that the floor is not polluted.

Detailed Description

The self-cleaning ceramic tile comprises a ceramic tile body 1 and a micro-nano structure layer formed on the surface of the ceramic tile body 1; the micro-nano structure on the surface of the ceramic tile enables a large amount of air to be stored between the concave and convex parts of the micro-nano structure, so that the stain can only contact with the mastoid surface of the micro-nano structure, the contact area of the stain and the surface of the ceramic tile is obviously reduced, the interface of the stain and the air is expanded, the stain cannot automatically expand, especially the water bead type stain can keep the spherical shape, and the super-hydrophobic and self-cleaning functions are realized.

In the embodiment, the micro-nano structure layer comprises an epoxy resin layer 2 formed on the surface of the ceramic tile body 1 and a micron-sized mastoid structure 3 formed on the epoxy resin layer 2; the epoxy resin layer 2 is a carrier of the micron-sized mastoid structure 3, can be well adhered to the surface of the tile body 1, and improves the connection strength and stability between the structural layers, so that the durability is improved.

In this embodiment, the material of the micron-sized mastoid structure 3 is a low surface energy material; the micron-sized mastoid forms surface roughness, and the self-cleaning property of the surface is improved. The low surface energy material is adopted, so that dust is not easy to adhere, the contact area between stains and the surface of the ceramic tile is reduced, the stains cannot adhere to the surface of the ceramic tile, and the stains can only be accumulated between gaps of the micron-sized mastoid structure 3, so that the stains can easily fall off and can be easily washed clean by rainwater, and the self-cleaning effect is achieved.

In the embodiment, the diameter of the nano-pillars is 500-800nm, and the distance between the nano-pillars is 500-700 nm; the roughness constructed by the regularly arranged nano-protrusions enables the surface of the nano-protrusions to stably adsorb the formed air film, and induces the super-hydrophobic property of the nano-protrusions, so that the self-cleaning function is ensured. Preferably, the top surface of the nano-pillar is in a spherical shape.

In this embodiment, the low surface energy material is fumed silica.
