The present invention relates to an ocher tile and a method of manufacturing the same, and more particularly, to generate a large amount of far infrared rays, to have a very beneficial effect on the human body by performing antibacterial, deodorizing, moisture-proof, etc., while appropriately adjusting the humidity of the room pleasant The present invention relates to an ocher tile capable of providing a residential environment and a method of manufacturing the same.

Due to the industrialization of cities and farming and fishing villages due to the development of technology, it has been a long time since most residential spaces are built with cement and concrete, and the buildings built with cement and concrete have artificially controlled indoor ventilation, humidity, and temperature. By doing so, even if living in a state that is almost exposed to electromagnetic waves, not too much, the chemical substances such as nano-gas generated from cement, concrete accumulate and adversely affect the human body, causing the so-called modern disease more and more.

Therefore, according to the situation of the times, loess, which is a raw material of Korea's own building materials, has recently been in the spotlight again, which is good for the human body because it has excellent temperature control ability and emits a large amount of far infrared rays, It is cool and warm in winter, and the humidity control and ventilation function is superior to other materials, and the raw material is easy to purchase, so it is in the spotlight as an architectural material for an apartment or a building.

This loess is mainly distributed in Northeast Asia, including the Korean Peninsula and the Yellow River coast of China's North China, and mainly contains quartz, and other yellowish brown lime that contains fluorite, hornblende, and so on. It is excellent and has been known to have a beneficial weakness to the human body.

In recent years, many studies have been conducted on scientific research on ocher, and the ocher emits a large amount of far infrared rays and blocks harmful electromagnetic waves.The amount of ocher cutlery contains hundreds of millions of microorganisms and various enzymes, It has also been scientifically proven to have a very beneficial effect on the human body in many ways. Thus, ocher has been spotlighted as a material for living furniture, such as bedding mats, ocher beds, food containers for building or building, interior materials, exterior materials, and ondol, and the range of their application is also rapidly increasing.

On the other hand, pure ocher has poor thermal conductivity and heat storage property, and when mixed with water, its viscosity is so large that it is difficult to be molded into a specific shape, and after curing (after moisture evaporates), cracks are formed on the surface. There is a problem that it is difficult to commercialize by itself.

Thus, conventionally, ocher products are mixed and kneaded with other materials such as cement, lime, sand or stone, and then put into a specific mold and then cured ocher products (eg, ocher mats, various food containers, building interior materials (ocher tiles), etc.). ) Have been used.

For example, Korean Patent Application No. 97-62065 discloses 5% by weight of lignin sulfonic acid based on 95% by weight of aged ocher after correcting the moisture content to 28% by selecting the raw ocher with a sieve of low particle size and aging for 24 hours. A loess brick is disclosed in which a salt is added, kneaded with a vacuum drill, press-molded, and gradually heated and dried at 100 to 150 ° C.

In addition, Korean Patent Application No. 2003-0023928 discloses a building material composed of 5 to 15 parts by weight of ultralight agent, 1 to 3 parts by weight of pulp, 3 to 10 parts by weight of starch powder, and 50 to 100 parts by weight of water, based on 100 parts by weight of yellow soil. The ocher tile composition for use and the ocher composition are mixed, put into a standardized mold, flattened to a desired thickness, and then provided with a molded product, and the temperature of the molded product is raised to 75 to 95 ° C. while being moistened above the moisture content of the molded product. After the molded article is heated, the moisture is removed and the method is dried at 70 to 120 ° C. for 18 to 24 hours.

However, in the case of conventional loess products as described above, the content of loess is too low, while other compositions, such as high molecular compounds, cement or lime, dilute the function of loess, so that the inherent efficacy of loess can be effectively saved. In addition, the method by drying after molding had a problem that the strength was lowered and distortion occurred when baking at a high temperature.

Accordingly, it is an object of the present invention to provide an ocher tile having a high strength without warping and effectively exhibiting the inherent efficacy of ocher and a method of manufacturing the same.

Can be.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view of an ocher tile according to the invention. As shown in Fig. 1, the ocher tile 1 according to the present invention is formed of a square plate having a surface portion 2 and a back portion 3 formed of an uneven surface. The ocher tile 1 according to the invention is preferably made of a square plate having a size of 300 × 300 × 30 mm. The ocher tile 1 is a fine sand mixture consisting of 85 to 90% by volume of ocher powder from which impurities such as sand, small stones, etc. have been removed, and 15 to 10% by volume of low melting point sand, for example, a dolomite component having a particle size of 800 mesh. Is made with.
The sand used for the ocher tile 1 of the present invention is not only low melting point sand containing a dolomite component, but the surface portion may be provided with acupressure irregularities. Preferably, using sand that does not contain iron is most effective in terms of fundamentally preventing rust generation.

The surface portion 2 is smoothly coated by molten sand by melting the sand on the surface when the low melting point sand used to make the ocher tile 1 is baked at a high temperature, for example, 900 ° C. . Therefore, the ocher tile 1 according to the present invention is prevented from being buried or blown off from the surface when the ocher tile 1 is installed on the floor or wall, etc., while the penetration of the liquid such as water into the ocher tile 1 is suppressed. On the other hand, according to the present invention, the back portion 3 directly installed on the floor or wall is treated to have hygroscopicity so that it can be easily installed on mortar or the like.

The uneven surface formed on the rear surface portion 3 has a depth of about 1/3 to 1 / 3.5 of the total thickness of the ocher tile 1 and a width of about 20 mm, and the shape is formed in a dovetail shape. . Therefore, when the ocher tile 1 according to the present invention is installed in a living room or room floor as shown in FIG. 2, the uneven surface provided on the rear surface portion 3 of the ocher tile 1 is formed in a misaligned shape. Therefore, the uneven surface of the back surface portion 3 is embedded in the mortar layer 4, and the mortar layer 4 is firmly cured, thereby preventing the ocher tile 1 from being separated from the cured mortar layer 4. Can be. In addition, since the back surface portion 3 has hygroscopicity, when the ocher tile 1 is installed in the mortar layer 4, moisture in the mortar is absorbed by the back surface portion 3, so that the mortar layer 4 Cohesion can be improved.

On the other hand, when the ocher tile 1 according to the invention is installed on the floor is arranged to be away from the heating pipe 6 as shown in Figure 4, for this purpose, the thickness of the mortar layer 4 is the heating pipe (6) It is preferable to laminate | stack more than the outer diameter height of (). The ocher tile 1 produced according to the present invention has a higher thermal conductivity than cement which forms the floor of a conventional room or living room, so that heat is more easily conducted from the heating pipe 6. In addition, when the ocher tile 1 according to the present invention is installed on the floor of the living room or room, due to the inherent characteristics of the ocher, condensation may be prevented due to temperature difference between indoor and outdoor in the rainy season or in winter, Although the thermal conductivity is great, even if the heating is not in winter, the floor can be prevented to cool.

As shown in FIG. 3, the ocher tile 1 according to the invention may preferably be provided with acupressure projections 5 on the surface part 2. The ocher tile 1 provided with such acupressure protrusions 5 may be constructed at one corner of a room or living room, so as to obtain a acupressure effect by walking or pressing on the acupressure protrusions 5. Acupressure projections 5 provided on the surface portion 2 may be made in other forms in addition to the form shown in the figure.

As described above, the ocher tile 1 according to the present invention removes impurities from the loess by using a sieve having a mesh of more than 40 mesh in the ocher collected and dried. As described above, by sieving the dried ocher, impurities such as sand, small stones and the like contained in the ocher are removed, so that the ocher powder having a constant particle size can be obtained.

85 to 90% by volume of ocher dust from which impurities such as sand and small stones are removed, and 15 to 10% by volume of low melting sand, for example, fine sand composed mainly of dolomite with a particle size of 800 mesh. The sand mixed with the loess is prepared by using a sieve having a particle size of 800 mesh in the water from which sand is collected. At this time, it is preferable that sand is used to prevent the formation of rust by collecting and using sand without iron, and when sand of a suitable particle size is collected by a sieve, sand containing iron sinks in running water. It can be screened with iron-free sand.

This sand is mixed with loess and aged (fermented) for 40-50 days at a temperature of 60-70 ° C. According to the present invention, iron-free relatively fine (soft) sand and ocher powder are mixed and aged in a aging room for 40 to 50 days at a temperature of 60 to 70 ° C., so that the viscous force (viscosity) of the ocher powder is alleviated by sand. While the molding is prevented from cracking when the molding is dried, the warpage is prevented from occurring during the baking process during the manufacture of the ocher tile 1, so that the ocher tile 1 can be constructed exactly horizontally.

The ocher tile 1 according to the present invention is kneaded by mixing 10 to 20 parts by weight of water with respect to 100 parts by weight of the sandy mixed ocher powder aged as described above. The dough of ocher powder and water is appropriately kneaded so that the dough state, such as flour dough when making noodles, is prevented, and generation of air in the dough is prevented.

Such ocher dough is molded into a shape as described above using a compression molding machine (press). It is then naturally dried for at least 48 hours, preferably naturally in the shade, to remove moisture from the moldings. The ocher tile moldings from which moisture has been sufficiently removed by natural drying are arranged in a gas kiln such that the rear portions 3 of the pair of ocher tiles 1 face each other and come into contact with each other, as shown in FIG. 4. It is baked for 11 to 13 hours, preferably for 12 hours at a temperature of 950 ° C, preferably about 900 ° C.

As described above, since the pair of ocher tiles 1 are arranged such that the back portions 3 abut each other, hot passages 7 are formed between the ocher tiles 1 by the uneven surface, and in the gas furnace Hot air of 850 to 950 ° C., preferably 900 ° C., is directed to the side on which the heat passages 7 of the ocher tile 1 are formed, as shown in FIG. 4. Thus, the low melting fine sand in the ocher tile 1 is melted by heat, and the molten sand coats the surface of the ocher tile 1. By this coating layer, it is possible to prevent the liquid and the like from being absorbed into the ocher tile 1. On the other hand, since the back surface portion 3 of the ocher tile 1 in contact with each other does not directly contact with heat, sand is prevented from being completely melted, so that strength of reinforcement by baking operation can be reinforced and hygroscopicity can be maintained.

As described above, by baking the ocher tile moldings in the gas furnace, the sand inside is partially melted, causing strong bonding of the ocher powder, thereby increasing the strength of the ocher tile 1, while on the surface of the ocher tile 1 The surface is smoothly coated by the melting of sand. Therefore, it is possible not only to prevent the ocher powder from flying or getting into the hands from the surface of the ocher tile 1, but also to have a high strength as compared with the conventional ocher tile.

The ocher tile 1 according to the present invention is mainly constructed in the living room or the floor, but can be used as a floor covering of a wall or an ocher bed by appropriately adjusting the overall thickness of the tile and the thickness of the uneven portion depending on the use purpose. For example, when used as a floor of an ocher bed as shown in FIG. 5, the ocher tile 1 has the entire surface of the ocher tile 1 in a state in which the uneven surface is removed or changed in the back surface part 3. The surface is baked in a gas furnace so that it is coated with molten sand. Thus, the ocher tile 1 is constructed in the bed portion of the bed frame 8 of wood or metal material, so that the ocher bed as shown in FIG. 5 can be completed.

According to the ocher tile according to the present invention as described above, since the molded product is baked to prevent the occurrence of ocher powder, damage due to impact and heating can be prevented, while durability can be improved and used for a long time.

In addition, the ocher tile according to the present invention is prevented from warping during baking of the molding because the ocher and sand mixture is aged at a predetermined temperature for a predetermined period of time, while the content of ocher is high, and thus the inherent of the ocher Efficacy can be effectively utilized, and the results of the experiment confirmed that the far-infrared emission amount was more than 97%.
