DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to architectural tiles, and more particularly, to architectural tiles used for wall construction of buildings.

[0002]

2. Description of the Related Art As a building tile, cement, plaster,
A blend of a hydraulic material such as plaster is known. It has also been proposed to manufacture a lightweight building tile having a cellular structure using a cellular concrete material which is a similar hydraulic material and is also called ALC. By using the hydraulic material as described above, after the tile raw material is formed into a predetermined shape, it can be cured by steam curing or the like without firing. A large-scale apparatus such as a firing furnace is not required, and productivity is improved.

[0003] In places where the construction environment of the building tiles is humid or where water easily adheres, molds may be generated on the building tiles. Therefore, it has been proposed to spray or apply a fungicide solution to the construction surface of the building tile.

[0004]

Even if the surface of a building tile is treated with an antifungal agent, the effect of the antifungal agent is diminished over time, and the occurrence and propagation of fungi cannot often be sufficiently prevented. When the surface of the building tile is wet with water or washed to remove dirt on the surface, the antifungal agent attached to the surface is easily removed. In the case of non-fired building tiles using the hydraulic material described above, there is a tendency for mold to be generated or propagated more easily than fired tiles, and even if antifungal treatment is performed as described above, The effect is lost within a short period of time, causing mold damage. When mold generated on the surface of the building tile enters the inside of the building tile, it is difficult to sufficiently remove the mold even by performing a mold removing treatment such as washing.

An object of the present invention is to provide an architectural tile, especially AL
An object of the present invention is to provide a building tile using a C material, which can reliably prevent the generation and propagation of fungi for a long period of time.

[0006]

According to the present invention, there is provided an architectural tile comprising: a main body layer made of a material in which ALC powder and reinforcing fibers are blended; and a main body layer laminated on the main body layer. An antifungal surface layer made of a material containing an antifungal agent. [ALC powder] ALC (Autoclaved Lightweight Concr
ete), that is, the raw material for lightweight cellular concrete. Specifically, an aluminum powder or the like is mixed with a normal concrete material such as quicklime or cement, and provided as a powdery material.

[Reinforcing fiber] A fiber material blended for reinforcing various building members and improving properties is used. Specifically, synthetic fibers such as nylon and vinylon can be used.
The reinforcing fibers are preferably used in the form of relatively short fibers. [Antifungic agent] An antifungal agent used in ordinary construction can be used. Specifically, those containing an organic halogen compound as an active ingredient ("Hocside 7400": trade name, manufactured by Hokuko Chemical Co., Ltd.) and the like can be used.

It is preferable to use a powdery material in accordance with the ALC powder as a fungicide. [Building tile] A laminated structure of a main body layer and a fungicide surface layer. The main body layer constituting the main body part of the building tile is A
It is made of a material in which LC powder and reinforcing fibers are blended. The fungicide surface layer, which is disposed on the surface of the main body layer and constitutes a surface exposed to the outside during use, is made of a material in which a fungicide is added in addition to the material of the main body layer. The thicker the antifungal surface layer,
The desired antifungal effect is improved. However, in terms of strength and other basic characteristics of the building tile, it is not preferable that the mold-proof surface layer be too thick. When the antifungal surface layer becomes thick, the amount of the antifungal agent used also increases, and the production cost increases.

Therefore, it is preferable that the thickness of the main body layer is set in the range of 5 to 15 mm, and the thickness of the fungicide surface layer is set in the range of 1 to 5 mm. The ratio of the thickness of the fungicide surface layer to the total thickness of the building tile can be set to 5 to 35%. For the planar shape and other detailed shapes of the building tile, the same technology as that of a normal building tile can be applied. For example, the planar shape of the building tile is generally a rectangle, but other curved shapes such as a polygon, a circle, and an oval can also be adopted. [Manufacture of Architectural Tiles] Basically, the same manufacturing apparatus and manufacturing process as those of ordinary architectural tiles can be employed.

As the tile raw material, the above-mentioned ALC powder,
Reinforcing fibers and fungicides are used. If necessary, various additives for producing tiles, coloring agents, and the like can be added. The tile material of the main body layer and the tile material of the fungicide surface layer may be separately prepared, or after preparing the tile material of the body layer, only a part of the tile material is taken out.
Tile raw materials for the fungicide surface layer can be prepared by additionally blending a fungicide. The compounding amount of the fungicide can be set in the range of 1 to 20% by weight based on the whole tile material of the fungicide surface layer. It is preferable to adjust the amount of water contained by adding water to the tile raw material. The amount of water
It can be set in the range of 30 to 100% by weight based on the weight of other tile raw materials.

A tile material is formed into a predetermined tile shape. The forming apparatus and the forming method may be the same as those of ordinary tile production. For example, press molding is employed. In order to laminate and integrate the main body layer and the fungicide surface layer, when the tile raw materials are supplied to the mold, they may be supplied in order and deposited in layers. Those in which a main body layer and a fungicide surface layer are separately deposited in advance can be stacked and integrated. The molded body is steam cured, autoclaved, heat dried,
Cure by natural curing or other means. Before curing, the molded body may be cut or machined.

When the molded product is sufficiently cured, it can be used as an architectural tile.
