Description

Dressing body composition used for clay bricks}

The present invention relates to a makeup holding composition to be applied to the surface of the brick and a method of manufacturing a dressing brick using the same, and more specifically, to remove the adhesion and cracking defects of the brick and the makeup in the makeup brick similar to the brick substrate The present invention relates to a clay-feldspar, feldspar, feldspar, and inorganic pigments having a specific thermal expansion coefficient and particle size and containing inorganic pigments that can be expressed in various colors such as orange and red, and a method of manufacturing a makeup brick using the same. .

Here, the makeup means a generic term for the makeup to be painted on the surface of the body in order to hide the original color of the body, and the makeup means the body made for makeup.

In general, brick is a kind of material used as a finishing material for buildings. The bricks currently produced in Korea are mainly made of clay and kaolin, and clay bricks and kaolin bricks have a dark red color after firing under the influence of a large amount of iron oxide contained in clay or kaolin. . These bricks were mainly used as finishing materials for buildings with simple functions, but today they have different utility as decorative materials that emphasize color and design in terms of creating aesthetic value and creating abundant living space. The trend is prominent.

Thus, there have been attempts to diversify the color of the bricks.

Patent Application Publication No. 1998-027305 discloses a preliminary coating (0.3 mm ±) of a brick material heated to 30 to 50 ° C, and then sprayed on the surface with a bright colored glaze liquid in the primary oil chamber. It describes a method of producing colored bricks by spray coating (0.2 mm ±) thinly with glaze liquid of desired color in the oil chamber.

Patent application publication No. 2000-0054933 is a white clay containing 15 wt% to 30 wt% kaolin and 7 wt% to 30 wt% seaweed grass on a crematorium (engobera) applied to the outer surface of green bricks. A method of applying a viscous engobe for brick-based manufacturing to discolor the dark red color developed during sintering with iron contained in brick bricks. Introduces a method of manufacturing viscous engobe for white bricks, which can prevent desorption from brick surface due to the viscosity of seaweed grass (See Weed Paste).

In addition, Korean Patent Application Laid-Open No. 1999-016879 discloses coating a brick with a thickness of 1 to 20 mm using a clay for coating 30% or more of clay having an iron oxide content of less than 5% after molding a clay brick in a conventional manner. It introduces the manufacturing method of the type clay brick.

However, these conventional methods are cumbersome to apply two or more steps to apply makeup to brick materials, or to use organic materials as a binder, and the coefficient of thermal expansion of the substrate and glaze or coating agent during firing. There is a risk of cracking due to the car, especially in the case of glaze, the glass part may be broken by light contact even during the use of the product. In addition, there is a disadvantage that does not give a variety of changes in color.

Accordingly, an object of the present invention is to provide a makeup composition for clay and kaolin bricks, which are orange and red in the makeup brick, which are cracked and completely adhered to the brick surface, and a method for manufacturing the makeup brick using the same. Doing.

The present inventors make a composition consisting of clay, feldspar, feldspar, and inorganic pigments of a specific composition, and a wetted mixture of the composition, which is molded by dipping or spraying the powder on the surface of the dry brick and baking it. The present invention is completed by knowing that the method of manufacturing a brick can achieve the above object.

1 is a view showing a dry brick after molding,

FIG. 2 is a view illustrating a form in which the mixed solution of the makeup composition and water of the present invention is sprayed on the brick of FIG. 1.

Therefore, according to the present invention, there is provided a makeup holding composition characterized by containing 100 parts by weight of an inorganic mineral consisting of 10 to 20 wt% of clay, 50 to 70 wt% of feldspar and 5 to 20 parts by weight of an inorganic pigment. .

In addition, the present invention is the ratio of the makeup composition and the water to 1: 0.6 ~ 0.8 to form a wet-mixed makeup made after the molding of the surface of the dry brick by dipping or spraying (0.1) to 0.3mm thickness It provides a manufacturing method of the makeup brick, characterized in that the firing at 1170 ~ 1210 ℃ temperature below 10% water absorption.

Hereinafter, the present invention will be described in more detail.

The makeup composition of the present invention contains 100 parts by weight of an inorganic mineral consisting of 10 to 20 wt% of clay, 50 to 70 wt% of feldspar and 5 to 20 parts by weight of an inorganic pigment.

When the clay, feldspar and feldspar constituting the inorganic mineral in the present composition is in the range as described above, it becomes possible to manufacture a dressing material for brick suitable for the purpose of the present invention.

In the composition, it is preferable that the clay is 10 to 20wt%. The clay has plasticity when water is added, and when it is dried, it shows elasticity, so it is used as a main raw material for making ceramic products, but 20wt When it exceeds%, it is preferable that it is 20 wt% or less because clay becomes a fine particle and dry shrinkage is large and it produces the effect which produces the crack by plastic shrinkage at the time of baking.

Moreover, it is preferable that feldspar is 50-70 wt% in the composition of this invention. Feldspar acts as a flux and should be more than 50wt% in order to form a glass phase during firing and bind the makeup body and brick, but when it exceeds 70wt%, a large amount of glass phase is generated, This impedes the binding and separates the make-up body due to a small collision when using the product.

Moreover, it is preferable that feldspar is 10-40 wt% in the composition of this invention. Although feldspar has some of the characteristics of clay, the plastic shrinkage rate is less than that of clay, so it is suitable to use 10 to 40 wt% in the present invention.

The particle size of the inorganic mineral in the composition is preferably in the range of 44 ~ 149㎛, because when the inorganic mineral has a particle size in the above range, the coefficient of thermal expansion of the brick body and the makeup body is similar to the makeup on the dry brick surface This is because when the plastic is fired, it can be completely attached to the surface of the brick without cracking the makeup.

In addition, the inorganic pigment constituting the makeup holding composition of the present invention should be contained in an amount of 5 to 20 parts by weight based on 100 parts by weight of an inorganic mineral composed of clay, feldspar and feldspar, for the reason of the content within the above range. This is because, when the inorganic pigment is contained, the color of the desired inorganic pigment is expressed when applied to the brick and fired. All kinds of inorganic pigments may be used in the present composition, and particularly preferred inorganic pigments of these are orange pigments containing zirconium (Zr), silicon (Si), selenium (Se) and the like.

Hereinafter, an example of a method of manufacturing makeup brick using the composition of the present invention will be described.

First, according to the present invention, a composition containing clay, feldspar, feldspar and pigment is wet mixed with water. In this case, the ratio of the composition to water is preferably 1: 0.6 to 0.8.

Next, the obtained mixture is applied to the surface of the brick to be dressed. As the coating method, it is preferable to use a dipping method or a spraying method.

Bricks coated with the makeup of the present invention as described above is preferably baked at a temperature of 1170 ~ 1210 ℃. The powdered brick thus obtained has a water absorption rate of 10% or less after firing, and the color falls within the range of L ^* = 60 ~ 90, a ^* = 1 ~ 90 and b ^* = 35 ~ 70 with L ^* a ^* b ^* values. .
