Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" This invention relates to the provision of a method for producing building materials that are shiny, hard, highly durable, and have a smooth surface.

``Prior Technology'' At present, there is no other glazed or enamel-finished tile that can produce a glossy, hard, durable, and clear surface. These items are made by putting them in a kiln and baking them at a temperature of around 1000 degrees Celsius.

``Problems to be solved by the invention'' However, with the above-mentioned means, there is a step of firing in a kiln during the manufacturing process, so there is a problem with the base material to be glazed, its size, and shape. subject to restrictions.

``Means for Solving Problems'' and ``Operations'' The present invention was made in view of the above circumstances, and its gist is to coat building materials with a ceramic coating by thermal spraying, and then coat the building materials with a polymer coating. The base material or size of glass that forms a glass-like layer by heating at room temperature or low temperature.

The object of the present invention is to provide a method for manufacturing a building material that is glossy, hard, highly durable, and has a smooth surface without being subject to shape restrictions.

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

In FIG. 1, reference numeral 1 indicates building materials, that is, concrete materials that are often used in the construction field, materials such as noncombustible boards, and metal materials such as aluminum. 2 in the figure is a ceramic coating layer formed on the surface of the building material 1 by thermal spraying.

As the thermal spraying method, any one of gas spraying, arc thermal spraying, plasma spraying, etc., which have already been developed in the field of ceramics and ceramics, may be used.

Ceramics include alumina, alumina/titania, titania, spinel, and zirconia.

Stabilized zirconia, alumina/cobalt, etc. are used.

By this treatment, the building material 1 can: i) have increased durability as an exterior material due to the ceramic layer 2;

ii) Since the coating is made of inorganic material, it is not suitable for building materials.
No chemical changes occur.

iii) There is no peeling because of the strong adhesion.

iv) Since it is not fired in a kiln like tile enamel, large panels can be made and there is almost no warping or deformation.

Benefits such as:

3 in the figure is a glass-like layer formed on the ceramic layer 2, which is formed by applying polymer glass by dipping, spraying, brushing, etc., and applying the amount of heat necessary for reaction or curing. It is.

Here, polymer glass is a silicone oligomer that is further condensed by low-temperature heating and has excellent heat resistance, adhesion, weather resistance, transparency, hardness, and abrasion resistance, and is different from conventional glass. It is a material with almost comparable characteristics,
Further, the required amount of heat is heating at room temperature to low temperature (around 200° C.).

By forming this glass-like layer 3, it plays the role of sealing the ceramic coating layer 2, and fully exhibits the features of polymer glass.

The products made in this way are either large glazed tiles or glazed ceramic tiles that are hard to break and have an excellent color, gloss, hardness, and weather resistance.

It has wear resistance and durability.

Examples of uses of the products of the present invention are as follows.

1. Execute on PCa version, GRC panel, Alcast, etc. to construct the outer wall.

2. Apply to GRC panels, non-combustible boards, etc. to construct walls and ceilings in places that require water resistance such as bathrooms, or special buildings such as Mesoki factories and chemical factories.

3. Implemented on PCa materials and metal members to create a 3-sided handrail lattice.

Configure louvers etc.

"Effects of the Invention" The above-described means of the present invention provides various effects as listed below.

1. All building materials can be coated with ceramic coating by thermal spraying (concrete materials,
(materials such as noncombustible boards, metal materials such as aluminum, etc.)

2. Large size (e.g. PCa version 2.500x) 3.
500) or can be applied to objects with complex shapes (for example, relief patterns).

3. It has high adhesion resistance and there is no need to worry about it peeling off like with tiles.

4. Like glazed tiles, it is highly weather resistant and durable.

5. High hardness and scratch resistant.

6. Various shades can be produced by thermal spraying materials, and the shades deepen with the glass layer.

7. The glass layer makes it hard to get dirty, making maintenance easier.

8. Can produce a luster similar to tile glaze.

9. The glass layer provides water resistance.
