Description

Technical Field [0001] The present invention relates to a method of manufacturing a loess tile using a loess mortar,

An embodiment of the present invention relates to a method for manufacturing a yellow clay tile using a mortar, and more particularly, to a method for manufacturing a yellow clay tile using a yellow clay mortar, will be.

Generally, a tile refers to a flat clay-like product made to cover the surface of a building such as a floor and a wall. There are various kinds according to the material of a tile and a use purpose, and it is easy to construct a kitchen, a bathroom, It is widely used in restrooms and the like.

As the tile for the finishing material of a building, a magnetic tile and a ceramic tile are mainly used. The production of the tile is composed of raw material mixing and crushing, powder manufacture, molding, drying, Thereby completing the manufacture. The tile thus manufactured is used as a building material for improving appearance of a building, which is used for the appearance and floor of a building. However, recently, functional ingredients such as a material and a glaze have been added in the production of tiles, Respectively.

Particularly, as a result of inducing modern diseases such as atopy, a functional tile which is excellent in deodorization, ventilation, and moisture-proofing action, and which imparts functions such as heat insulation and heat insulation effect has been attracting attention.

The existing porcelain tiles and porcelain tiles are fired in the range of 1000 ~ 1200 ℃ to remove the organic substances in the tiles and to maintain the strength of the products. However, the above-mentioned manufacturing process has a problem that it is difficult to produce a functional tile having a unique fragrance or absorbing and releasing moisture. Therefore, it is urgent to develop eco-friendly tiles that can keep the original fragrance, keep the water suitable for the human body constantly, and absorb and emit moisture to maintain a favorable humidity for the human body at all times.

As interest in well-being has increased in recent years, demand for building materials using yellow clay is increasing rapidly, and various building materials products using yellow clay are being released.

Since the temperature of the loess is not raised above 100 ° C, it can delay the initial ignition and combustion of the building, and it has a low thermal conductivity, so it has excellent heat insulation. It also emits a large amount of far infrared rays and can block harmful electromagnetic waves. It has been scientifically proven that there are hundreds of millions of microorganisms and diverse enzymes in the sheep, and they have a very beneficial effect on the human body in many ways by circulating.

However, when a structure containing bricks is formed with only yellow clay, the strength of binding between the molecules of the yellow clay decreases and the strength and durability of the yellow clay on the block surface are low, and surface cracks occur. In addition, to increase the bonding of the loess, the cement is combined to produce the loam building material, which is superior to the pure loam building material in terms of bonding strength. However, it is harmful to the human body, There is a problem that not only the merit of being possessed is not fully resurrected but also it is not environmentally friendly.

These and other objects, features and other advantages of the present invention will become more apparent by describing in detail preferred embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for manufacturing a clay tile using the clay mortar of the present invention will be described in detail with reference to the accompanying drawings. For purposes of this specification, like reference numerals in the drawings denote like elements unless otherwise indicated.

1 is a flowchart illustrating a method for manufacturing a yellow clay tile using an ocher mortar according to an embodiment of the present invention.

As shown in FIG. 1, a method for producing a yellow clay tile using an ocher mortar according to an embodiment of the present invention comprises the steps of: preparing an aqueous solution by mixing water with a water-soluble acrylic resin or a water-soluble epoxy resin; Finely pulverizing the paper into a powder form to form paper powder; S30, in which the aqueous solution and paper powder are put into a blender and stirred to dissolve the paper powder to prepare a mixture; Adding Sulfur flour to the mixture and stirring to prepare an ocher mortar; Finely crushing the loess mortar; And a step S60 of pouring the crushed ocher mortar into a mold having a predetermined size and curing it.

First, in step S10, 60 to 80% by weight of water is immersed in a bucket, and 20 to 40% by weight of a water-soluble acrylic resin or a water-soluble epoxy resin is slowly added thereto while stirring with a stirrer to prepare an aqueous solution.

Here, the aqueous solution has adhesiveness and water resistance of the loess itself, prevents the loess of the loess itself, and prevents cracking. It may also act as an adhesive on the surface to be adhered.

In step S20, the paper is first cut to a predetermined size, and then finely pulverized in a powder form to form paper dust.

In the step S30, the aqueous solution prepared in the step S10 and the paper dust pulverized in the step S20 are put into a blender, and the mixture is stirred by stirring for a certain time so that the paper flour is loosened. At this time, the paper powder is mixed in an amount of 5.6 to 19.6 parts by weight based on 100 parts by weight of the aqueous solution.

If the amount of the paper powder is less than 3% by weight, cracking will occur severely and the effect will not be obtained. If the weight ratio is more than 10%, the effect of preventing cracking will increase, but the microorganisms and moisture in the loess powder The paper powder may be corrupted due to the reaction, and the color of the corrupt paper powder may change to black and odor may be generated.

In step S40, 68.5 to 88.8 parts by weight of loess powder is added to 100 parts by weight of the mixture prepared in step S30 and stirred to prepare an ocher mortar.

Here, the loess flour may be one that is commonly used. For example, SiO ₂ , Al ₂ O ₃ and Fe ₂ O ₃ can be contained as main components, and 40 to 70 wt% of SiO _2, 10 to 30 wt% of Al ₂ O ₃ , 5 to 20 wt% of Fe ₂ O ₃ By weight and other components such as CaO, MgO, K ₂ O, Na ₂ O and TiO ₂ in an amount of 1 to 10% by weight. When such yellow loess is used, physical properties such as appearance, heat insulation, formability and durability can be excellent, and components useful for the body such as far-infrared rays and anions can be emitted along with the fragrance inherent in the yellow loess tile.

In addition, the loess powder can be used by screening with a uniform particle size of 150 to 350 mesh. Preferably 180 to 320 mesh. More preferably 200 to 300 mesh. When the yellow loess of the above-mentioned particle size is used, it is possible to provide appropriate formability and to have excellent physical properties such as durability.

In addition, the yellow clay can be used by aging. In one embodiment, the ground loess powder may be put into a silo room or a hopper and aged at room temperature for about 1 to 10 days. Under the above-mentioned conditions, the beneficial and various microorganisms present in the loess powder at the time of aging can further enhance the intrinsic fragrance of the loess, and further improve the antibacterial and deodorizing effects of the loess tile.

In step S50, the mortar is crushed into a predetermined size.

In step S60, various standard sizes of the frame may be used. However, if the specification is specified specifically, dimensions of 150 ~ 350mm × 100~300mm × 5~12mm thickness may be used. More specifically, a frame having a size of 200 mm x 150 mm x 10 mm thick can be used. In addition, in consideration of the precise moldability and the production efficiency of the yellow clay tile, the frame may be formed by appropriately mixing a metal plate material and a silicon material.

In addition, the step S60 may further include the step of removing the air inside by pressurizing the yellow mortar poured into the mold at 100 to 200 kgf / cm2. Here, removal of air can improve tile formability and strength after curing.

Further, in step S60, the curing is naturally dried in the shade or dark place for 24 to 50 hours.

FIG. 2 is a flowchart illustrating a method for manufacturing a yellow clay tile using a clay mortar according to another embodiment of the present invention.

As shown in FIG. 2, another embodiment of the method for producing the yellow loam tile using the yellow mortar comprises 51 to 53.5% by weight of an aqueous solution prepared by mixing 60 to 80% by weight of water with 20 to 40% by weight of water- , S100 in which 3 to 10% by weight of paper powder and 43.5 to 48% by weight of loess powder are mixed and stirred to produce an ocher mortar; Finely crushing the loess mortar; And pouring the crushed ocher mortar into a mold having a predetermined size to cure the crushed ocher mortar.
