JPH08217573A - Tile aged with time - Google Patents

Abstract

PURPOSE: To obtain an exterior tile with the color tone aged with the lapse of time and exhibiting a magnificent and grave effect considering that the conventional exterior tile for building and structure is conspicuously contaminated on aging and the appearance is spoiled. CONSTITUTION: The section of a tile A consists of two layers of clay grounds having a different property, starch, cornstarch or the powder of natural fiber or the powder of a high molecular compd. is mixed in the clay of the surface layer 1, and the main body 2 consists of an ordinary clay. The surface layer 1 is firmly bonded to the main body 2 in calcination, and the substance mixed in the surface layer 1 is burned off in calcination to form a micropore 4. A metal powder or metallic compd. powder 3 is infiltrated into the micropore and fixed to obtain the tile aged with time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile used for the exterior of a building or a structure above ground, and the color tone of the exterior tile surface changes due to oxygen and moisture in the atmosphere after the years of construction. , To enhance the aesthetic landscape of buildings.

[0002]

2. Description of the Related Art The exterior tiles used in conventional buildings, etc., retain a beautiful and beautiful landscape as long as the new tiles are shiny and lustrous, but gradually lose their light stain and shine as time passes. Go on.

Stone structures and brick-made structures have a more profound feeling over time and the scenery thereof improves, but the outer walls of the tiles are only dirty and dirty.

The reason why such stains are strongly recognized is that light reflection due to glaze on the tile surface is significantly impaired by deposition such as dust, and the colored pattern is disturbed.

[0005]

The tile surface has a surface that prevents water from getting wet, permeates, prevents dirt from adhering, and prevents scratches and damage by improving surface hardness, improving chemical durability, improving uniformity, and coloring. A glaze treatment is performed for the purpose of facilitating glazing and improving decorative properties such as glazing.

The glaze is generally a so-called glass material containing silica, feldspar, and limestone as main components. The transparency and smoothness is the life of the glass material, but in the case of exterior tiles, the adhesion of dust partially impairs the transparency and smoothness, so that stains are noticeable and the appearance is significantly impaired.

Further, the wall surface of the dirty exterior tile is
Often, cleaning is performed, or when dirt is stuck and it is not easy to clean, tile replacement work will be performed. In other words, maintenance costs will increase.

An object of the present invention is to improve and eliminate the problems of such conventional exterior tiles.

[0009]

In order to solve the above-mentioned problems, the aged tile of the present invention does not stand out even if it is soiled by cliff dust and the like, and rather, it has a dignity and profound feeling aged over time. The substance adhered to the outer surface of the tile undergoes a chemical reaction with the passage of time to change the color tone and texture.

At the stage of manufacturing the tile material, the main body portion and the surface layer portion are mixed and mixed separately. The main material is the conventional tile material, but the surface material is a powdery substance that burns off when the tile is fired, such as starch, corn starch, natural fiber powder, or polymer compound powder. To do.

The thus-prepared base material flat plate of the tile main body and the base material flat plate of the surface layer portion are coated with an adhesive which is fixed during firing, and fired in a stacking furnace.

The surface layer portion of the tile after burning has a porous structure in which a burnable substance remains, and a metal powder or a powder of a metal compound is dissolved in a solvent and impregnated and fixed to the portion. Ultrasonic vibration or the like is applied to fill the porous structure of the tile with metal powder or the like dissolved in a solvent. Further, the fixing material of the polymer compound is also dissolved in the solvent.

[0013]

[Function] If metal powder or metal compound powder is impregnated and adhered to the outer surface of the tile when it becomes porous, the tile may be installed on the outer wall of a building or structure and exposed to wind and rain. The color tone of the metal powder or the metal compound powder changes as soon as an oxidation reaction occurs. For example, in the case of copper-based metal compound powder, the outer surface of the tile turns green.

The color tone aged as described above has been favored by everyone since ancient times as a solemn, profound and calm color. This aging of the exterior walls of modern buildings is highly desirable.

Further, by utilizing the fact that the color tone changes with aging over time, a pattern may be raised on the wall surface by combining tiles having different aging characteristics, or the color tone change may occur multiple times over a long period of time. it can.

[0016]

Embodiments will be described below with reference to the drawings. FIG. 1 shows the plane of the aged tile A. As for the side surface, as shown in FIG. 2, the surface layer portion 1 is made by kneading starch, cornstarch, natural fiber powder, polymer compound powder, or the like, which is burnt off during firing. The main body 2 of the aged tile A is a normal material.

When the aged tile A is fired, as shown in FIG. 3, innumerable fine holes 4 formed by the burned substance in the surface layer are formed. When the metal compound powder 3 is impregnated and fixed, the aged tile A is completed.

[0018]

As described above in detail, according to the present invention, it is possible to obtain an aged tile in which the color tone of the tile used for the outer wall of a building or structure changes with time.

Claims (1)

[Claims] 1. In a porcelain or glazed exterior tile, a fine substance that burns down at a high temperature is carefully prepared in a clay dough so that a portion having a predetermined thickness of an outer surface layer portion has a fine porous structure after firing. It is kneaded, and after being baked, it is a fine metal powder or metal compound powder that contains a substance that is a fine metal powder or metal compound powder that undergoes a chemical reaction due to oxygen and moisture in the air and whose color tone changes with age over time. Aged tiles that are characterized by that.
