Today, due to the development of construction technology, finishing work is being carried out to provide abrasion resistance and various decorative effect functions on the cement surface exposed to the outside of the structure such as walls, ceiling or floor of the building.

Clay bricks as well as architectural stones such as granite and marble are widely used as interior and exterior finishes for architectural use which can be used for such finishing work and can be adorned on the surfaces of walls and floors of buildings and have a beautiful appearance.

Generally, the clay bricks can be produced by a method in which an appropriate amount of clay, yellow soil, kaolin (white clay), and marathon are mixed in an appropriate amount, vacuum-kneaded and extruded to produce a brick molding, and then the brick molding is dried and baked in a baking kiln.

The raw materials used in the manufacture of clay bricks are rough and porous because the raw materials used in the manufacture of the clay are mixed with natural raw materials such as kaolin (clay), kaolin (clay) and feldspar, and are formed by wet milling. Therefore, the clay brick is uniformly flat in its appearance, and lacks in its own decoration.

In order to solve such a problem, Japanese Patent Registration No. 10-0609929 discloses a composition composed of a plastic clay, clay, kaolin, feldspar, glass powder, frit, and the like on the surface of a wet- To 6 mm particles, followed by drying and firing, thereby producing a natural marble-like clay brick which is harmonized with each other by clearly distinguishing the color of each spot.

Therefore, the definition should be based on the contents throughout this specification.

Hereinafter, preferred embodiments of the glaze brick using mica and the method for manufacturing the same according to the present invention will be described in detail.

First, the glaze brick according to the present invention is coated with a glaze on the surface of a wet brick formed through the production and molding steps of the base paper to form light or color. At this time, the glaze applied on the surface of the brick base is composed of clay powder 60 to 30% by weight, 20 to 5% by weight of sodium phosphate, 40 to 10% by weight of frit powder, 10 to 5% by weight of a selected one of zirconium oxide (ZrO ₂ ), titanium oxide (TiO ₂ ) % Of feldspar, 30 to 10 wt.% Of feldspar, and 10 to 5 wt.% Of mica powder together with water to form a slip (suspension or slurry of finely divided ceramic material in liquid).

The glaze composition is finely pulverized to a size of 50 mesh or less, which is mixed with water and kneaded. At this time, the amount of water is mixed at a ratio of about 20 to 30% of 100% by weight of the whole glaze composition.

The clay powder is highly viscous and improves the strength of the dry brick.

The feldspar and frit brighten the speckle pattern after firing and increase the strength, but when it exceeds 45%, it interferes with the dry strength

The zirconium oxide (ZrO ₂ ), titanium oxide (TiO ₂ ) and inorganic pigment determine the color of the spots of the brick. In the case of red, it is possible to use red inorganic pigments and black to use black inorganic pigments, which are commonly used in tiles and ceramics.

The glaze used in the glaze brick of the present invention is natural mica, which is an important coarse rock mineral in granite. It is a layered silicate mineral with a hardness of 2.5 to 4, a specific gravity of 2.75 to 3.2, a yellow, Has a property.

The mica (sericite, muscovite, black pig) is finely pulverized to a size of 325 to 10 mesh to form a mica flour, and 10 to 5% by weight of the pulverized mica powder is mixed with the glaze composition.

The mica powder forms a surface color of the brick in gold or yellow. In order to manufacture a conventional gold glaze brick, an expensive gold powder or a platinum powder is mixed with a glaze, and the mixture is sprayed or applied on the brick base surface. There is a remarkable effect that the problem of raising the brick manufacturing unit cost can be solved.

That is, by using mica which is easily obtainable for producing gold bricks, cheap in price and easy to manufacture, expensive gold or platinum is used to solve the problem of conventional glazed bricks in which the price of gold bricks is increased It has a remarkable effect.

In addition, the use of natural mica not only improves the durability of the brick itself, but also has the advantage of generating far-infrared rays and negative ions.

On the other hand, carboxymethyl cellulose (CMC) may be used to improve the adhesion of the glaze on the surface of the wet brick base.

Next, a preferable method for producing glaze bricks containing mica as described above will be described in detail.

First, a green body is manufactured, and the green body is formed through a molding step in which the green body is put into a kneader and a molding machine. (101)

The formed brick pavement is sprayed with water to improve the adhesive force when applying the glaze to be described later.

The glaze may be a clay powder, a soda phosphate powder, a frit powder, a zirconium oxide powder or a titanium oxide (TiO 2) powder. ₂ ) or an inorganic pigment, fuller's powder and mica powder are mixed together with water to form a slip state. (102)

The proportion of the glaze composition is 60 to 30% by weight of clay powder, 20 to 5% by weight of sodium phosphate, 40 to 10% by weight of frit powder, zirconium oxide (ZrO ₂ ), titanium oxide (TiO ₂ ) 10 to 5% by weight of a selected one kind of inorganic pigments, 30 to 10% by weight of feldspar, and 10 to 5% by weight of mica powder are most preferred.

The glaze in the slip state, in which the mica powder is mixed, is applied to the wet brick base surface (103)

Then, the glazed brick is dried in a drying chamber at a temperature of 1,100 to 1,200 ° C. and then fired in a firing furnace to produce a glazed brick having a gold color. (104)

The glaze composition may contain 1 to 0.5% by weight of carboxymethyl cellulose (CMC) which improves the adhesion of the glaze when the glaze formed in the slip state is applied to the wet brick base.

The glazed brick of the present invention may be prepared by spraying the glaze on the surface of the dried brick having been subjected to the post-molding firing step, and then drying the glaze to dry it again to produce a golden brick.
