Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the provision of a water-impermeable building material with a stone-like surface consisting of a substrate that is unsuitable for thermal and adhesive direct ceramic spray coating.

Currently, there are stone, tiles, etc. as building materials that give off a stone feel, but although these materials have been improved little by little, little has changed, and these materials are also used as exterior or interior materials. Even if we compare and examine the required quality, durability, cost, etc., we cannot find any particular advantage. That is,
In the case of stone, there are two types of construction methods: the wet-type all-toro method and the belt-toro method, and the dry-type empty pile method and curtain wall method.The advantage is that it is highly durable, but it is also expensive. It has the following disadvantages.
In the case of tiles, the construction methods include improved stacking method, improved pressure bonding method, adhesion method,
It has the advantage of being a highly durable material, with many types of formwork attachment methods, but it has the disadvantages of not being able to make large objects as a single unit, and of being at high risk of peeling and falling.

As mentioned above, although conventional building materials with a stone texture exhibit excellent durability, they are inconvenient because the stones themselves must be piled or pasted. Therefore, in the 1980s,
Publication No. 73940 and other publications propose a new building material that creates a stone texture by providing a ceramic coating layer by thermal spraying on the surface of a base material that can withstand ceramic thermal spraying.

Moreover, since the base material is directly subjected to ceramic spraying, the base material is naturally required to have a certain heat resistance, so it cannot be applied to base materials that do not have heat resistance. Or, even if adhesive compatibility is poor, it will not be possible to obtain a suitable adhesive.In reality, there are restrictions on the base materials to which it can be applied, and water impermeability cannot be guaranteed with a thin coating layer. It has the disadvantage that it is unsuitable as a

The present invention was developed in view of the above circumstances, and its gist is that ceramic spray coating can be applied to base materials that cannot be applied using conventional techniques, and that even thin layers are water-impermeable. Concrete materials, materials such as noncombustible boards, copper materials, aluminum materials, etc.
Zinc is thermally sprayed onto a base material that is unsuitable for direct ceramic coating due to thermal or adhesive properties, and then ceramics are thermally sprayed to form a hard, highly durable coating layer, and a glass layer is then thermally sprayed on top of this. .

This will be explained in detail below based on the drawings.

The thermal spraying method used in the present invention includes a gas spraying method that has already been developed in the ceramics field,
Any method such as an arc spraying method or a plasma spraying method may be used.

The above-mentioned thermal spraying in the present invention is carried out after a zinc layer 2 is thermally sprayed onto the surface of a base material 1 which is not suitable for direct thermal spraying, as shown in FIG.

In other words, the zinc layer 2 compensates for the lack of heat resistance in the base material 1, and also improves the adhesion compatibility with the ceramic coating layer.

Therefore, a ceramic sprayed layer 4 is formed on the zinc layer 2.
Then, a glass layer 3 is also applied by thermal spraying.

The coating with the glass layer 3 imparts water permeability to the base material 1 .

The structure described above has the ceramic layer 4 coated on the surface of the base material 1, giving it a stone-like texture despite being a thin film, and has the following advantages.

(i) It is highly durable because it is inorganic (no deformation or deterioration) (ii) It has strong adhesion so there is no peeling.

(iii) It is hard to scratch because of its high hardness.

(iv) Since it is thermal sprayed, it can be made into various shapes.

(v) Thermal spraying is possible on various existing building materials (concrete materials, materials such as non-combustible boards, steel materials,
(aluminum materials, etc.) (vi) It can be thermally sprayed onto existing exterior walls to refresh it. (vii) It has a rough finish and is highly abrasion resistant, making it a non-slip material.

(viii) Can prevent rust on metals such as iron (can be applied to objects with complex shapes such as outdoor stairs and handrails, and can be used for long periods of time without maintenance).

(ix) Since it is chemical resistant, it can be used as an interior material for special buildings such as Metsuki factories and chemical factories.

As described above, according to the present invention, it is possible to provide a new stone-like building material that has various advantages not expected with conventional materials, and is extremely meaningful in practice.
