The present invention relates to a method of manufacturing a soil block that can be used as a building and civil engineering material, and more specifically, kneading a metal soap compound made of a polymer material having excellent water repellency, moisture resistance, weather resistance and adhesion to clay soil at a predetermined ratio. (Iii) by manufacturing a soil block, and relates to a method for producing a soil block using a polymer material that is environmentally friendly and has strength, durability, water resistance, etc. without damaging the nature of the soil.

Today's residential environment is transformed into cement structures, and our bodies are suffering from headaches, blood circulation disorders due to cold and fraud emitted from strong alkaline toxic factors of cement, and various pollutions, carcinogens and stresses caused by industrialization. Due to a variety of adult diseases and chronic diseases are busy.

Thus, a new perception has recently emerged from the scientific point of view of the usefulness of ocher clay bricks used in Hanok and thatch, our unique residential culture, and its usefulness has been scientifically proved, so that the interior and exterior walls of a business place or a sauna or sauna Occasional winds are blowing into the rooms, even apartments, which are modern houses. Soil bricks are stacked on the walls to form the walls.

The ocher soil is made of weathered granite and gneiss, and has been recognized as being excellent as a building material such as humidity control, far-infrared emission, heat storage effect, deodorization effect, insect repellent effect, and proved to be effective in treating various diseases.

In general, the clay brick was produced by pressing the clay to form a brick mold compression molding in the form of a brick, and then fired at a high temperature.

However, since these clay bricks were formed by using only clay components as raw materials, they were weakly damaged due to weak durability and cracked due to changes in the external temperature during drying, and they had little flexibility and elasticity. In addition, the insulation effect could not have the effect as expected, and there was no cushion, so it was not absorbed by the vibration, which was not suitable for the interior wall of the building.

In addition, the conventional brick brick is significantly lower than the strength of the cement brick, and become crumbly by water or other moisture, and when stacked as an inner wall of the building, there was a problem that it is difficult to paint or tile the wall.

In addition, in the past, the clay brick is baked at a high temperature, and a separate glaze is applied to the surface, so that the surface of the soil brick reads a natural aesthetic, and the unit price of the soil brick is increased.

Thus, in recent years, a number of prior arts have been proposed to solve the above-mentioned problems in the manufacture of soil brick. For example, "Preparation method of the soil brick and the soil brick made by the same method" of Korean Patent Publication No. 2001-44535 (June 5, 2001), "2006.38984 (2006. 5. 4) of the Patent Publication No. Ocher brick manufacturing method "," Patent manufacturing method of illite brick using activated carbon "of 2006-94423 (August 29, 2006).

In Korean Patent Laid-Open Publication No. 2001-44535 (June 5, 2001), "Dirt brick manufacturing method and the clay brick made by the same method" has a crevice, or The fiber is added and mixed, and the mixture is agitated by adding a small amount of sodium and lime, a natural adhesive made by mixing an appropriate amount of eggs in boiled coriander and elm, together with water, and stirring the mixture. Disclosed is a manufacturing process of a clay brick which is pressed into a mold and pressed to form a brick in a desired shape, and then naturally dried in the shade.

In "Ocher Brick Manufacturing Method" of Korean Patent Application Laid-Open No. 2006-38984 (May 4, 2006), a dry mixture in which moisture-removed ocher, powder, chaff powder, salt, rice powder, edible soda, etc. are mixed at a predetermined ratio. The mixture is kneaded with a mixture of a mixture of seaweed boiled water, elm boiled water, mulberry boiled water, water glass, etc. in a proportion. Disclosed is a process for producing ocher bricks which are dried at room temperature in the shade.

In the method of manufacturing an illite clay brick using activated carbon, Korean Patent Application Publication No. 2006-94423 (August 29, 2006) discloses a method of forming bricks by mixing activated carbon with illite, ocher and cement and compressing them using a hydraulic press. Disclosed is a content of heating by steam.

The manufacturing method of the soil brick disclosed in these prior arts by using cement or lime to fill the fragility of the soil, which not only damages the nature of the soil but also has problems in strength, durability and water resistance.

Accordingly, an object of the present invention is to mix the metal soap compound using a high-molecular material with excellent water repellency, moisture resistance, weather resistance and adhesion to the soil so that it is environmentally friendly and has strength, durability, and water resistance without damaging the nature of the soil. The present invention provides a method for manufacturing a soil block.

In order to achieve the above object, the manufacturing method of the earth block using the polymer material of the present invention, in the earth block manufacturing method, (1) stearic acid (stearic acid) mixed with caustic soda and water to make a metal soap (2) heating the vinyl chloride hybrid resin (EVA) and rosin to add the metal soap to the melted liquid water, and then stirring the mixture to make a soap mixture well until foaming, and (3) Boiling water together with polyvinyl alcohol (PVA) to liquefy transparently, and then put it in the metal soap combination and mix well to form a semi-solid metal soap compound, and (4) the semi-solid metal soap compound in ocher soil Mixing and kneading at a ratio to form a soil block by pressing, and (5) drying the molded soil block at room temperature.

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

Figure 1 shows a process for explaining the manufacturing method of the earth block using a polymer material according to the present invention.

2 parts by weight of rosin are dissolved in 10 parts by weight of vinyl chloride hybrid resin (EVA), which is a high molecular material, at 50 to 60 ° C. for liquidation. Here, EVA has moisture resistance, which is capable of releasing absorbed moisture into the air, and weather resistance, which is not easily decayed, and is used for preventing water from adhering and adhering. The rosin affects adhesion and drying and gives off a fragrance. Separately, 24 parts by weight of stearic acid (stearic acid) 72 parts by weight of water, 10 parts by weight of sodium hydroxide is mixed to boil to make a metal soap. Here, the stearic acid metal soap is well decomposed and evenly disperse the heterogeneous chemicals wrapped and exhibits a water-repellent property that water does not penetrate well. Add the stearic acid soap to the liquid made by adding and heating the rosin to EVA, and then stir well until the foam is formed.

Meanwhile, in another container, 100 parts by weight of water is boiled at 70 to 80 ° C. in 20 parts by weight of polyvinyl alcohol (PVA) to form a transparent liquid. Here, PVA binds to the fine particles of the soil by adhesion. After adding water to the PVA and heating it, add the metal soap combination, mix well, finish it with mild heat, and when the solution cools, it becomes a semi-solid metal soap compound. The metal soap compound thus made is kneaded and mixed with clay soil. At this time, the metal soap compound is kneaded well by extrusion by adding 5-10% of the amount of clay. In other words, when a mixture of ocher and metal soap is mixed at a ratio of 10: 1 and kneaded in a screw mixer, the fine particles of the soil are coated. The kneaded metal soap compound and the loess soil are pressurized and molded into a block of soil, and then commercialized at room temperature in a well-ventilated place. This creates a stone block of dirt.

In the present embodiment, although the amount of the metal soap compound 5 to 10 is mixed with the loess soil 100, it is necessary to adjust the mixing ratio of the metal soap compound according to the moisture content of the soil, and if the moisture is too high, it may cause a problem in the drying relationship. The water content of the soil is not taken into account here because it does not affect quality at all.

Soil blocks can be commercialized as building and civil engineering materials to replace cement products such as bricks, blocks, shafts, and rafting blocks.

As described above, the manufacturing method of the earth block using the polymer material of the present invention, without mixing cement or lime at all, melted the polymer material EVA, rosin, stearic acid, PVA and mixed with the ocher soil to earthen soil By processing into a block, it is environmentally friendly and has the effect of producing an earthen block having strength, durability and water resistance without damaging the nature of the soil.
