Description

TECHNICAL FIELD The present invention relates to a soil-water-soluble nano-particle-containing soil preparation and a method for producing the same. BACKGROUND ART [0002]

Field of the Invention [0002] The present invention relates to a soil agent that can be used as a fertilizer or the like and a method for producing the soil agent. More particularly, the present invention relates to a soil agent containing a carbon component and / or a silicon compound extracted from a specific natural mineral, The present invention relates to an eco-friendly water-soluble nanoparticle soil agent and a method for producing the same.

Silicon (Si) is the second most abundant element among the constituents of the crust. Such silicon exists mainly in the form of silicon dioxide such as silicon dioxide (SiO ₂ ) or silicate (Si (OH) ₄ ]) in the soil. In addition, most plants absorb silicon well. Depending on the kind of plant, for example, plants such as rice plants contain 10% by weight or more of silicon (silicic acid).

When silicic acid is absorbed into the plant, the leaves and stems become stiff and do not collapse well, and the bottom leaves of the plant are exposed to a lot of sunlight, so that the carbon assimilation becomes active. In addition, silicic acid is absorbed in the plant to form a siliceous layer (a cuticle layer) on the cell wall and strengthens the cells, thereby enhancing the resistance to blast disease and resistance to insects such as Euphorbiaceae and Bryophytes, It increases the resistance to rot, bacterial disease, viral disease as well as cold weather. In addition, silicate is effective in controlling soil improvement and fertilizer effect, preventing nitrogen and phosphorus absorption obstacles, maintaining freshness of plants, improving storage stability, and enhancing the hardness and sugar content of fruits. have.

Accordingly, silicate fertilizer is widely used as a soil growth promoter as well as a soil improvement agent. For example, Korean Patent No. 10-0415594 and Korean Patent No. 10-1246342 disclose techniques relating to silicate fertilizer.

 However, the conventional silicate fertilizer is a soluble silicate fertilizer mainly made of steel slag, which is almost insoluble, so that the amount of components that the plant can absorb is very small, and most of the remaining amount is accumulated in the soil. That is, the conventional silicate fertilizer has a high content of insoluble components, so that the amount absorbed by the plant is extremely small and the efficiency is low.

In addition, with regard to fertilizers and soil remediation agents, attempts have been made to manufacture by processing volcanic ash or natural materials. This is more environmentally friendly than chemical fertilizer. For example, Korean Patent Laid-Open No. 10-1996-000833 discloses a method for producing an acid soil improvement fertilizer using volcanic ash, Korean Patent Laid-Open No. 10-2006-0122228 discloses a method for producing acid soil improvement fertilizer using volcanic ash, clamshell, tourmaline, zeolite, A method for producing a soil improvement agent capable of adsorbing and removing contaminants by preparing a porous powder by burning a natural material such as light at a high temperature is proposed.

However, it is difficult for the soil material (fertilizer or soil remedy) produced from the above-described volcanic ash or natural material to contain the beneficial ingredient for the plant growth or to temporarily hold it and release it at a short time, effectively promoting the growth of the plant.

Korean Patent No. 10-0415594 Korean Patent No. 10-1246342 Korean Patent Publication No. 10-1996-000833 Korean Patent Publication No. 10-2006-0122228

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, exemplary embodiments of the present invention will be described below, but the technical spirit of the present invention is not limited thereto and can be variously modified or modified by those skilled in the art.

(1) Grinding (first step)

First, the natural minerals are crushed. The natural minerals are shungite minerals according to the present invention. The above-mentioned gut minerals mainly contain silicon (silicon compound) such as silicate, but also contain a large amount of carbon. At this time, most of the carbon components are fullerene. That is, the? -Gate includes at least 40% by weight of silicon, more than 25% by weight of carbon, more specifically about 25 to 50% by weight of carbon (fullerene) .

At this time, the carbon component (fullerene) contained in the gut mineral has a matrix form of a porous sponge structure, the porous cell is filled with silicon-containing mineral particles (such as silicate) The main component of the particles is silicon dioxide (SiO ₂ ) or the like. Most of the silica-rich mineral particles have a particle size distribution of about 0.1 to 5 μm, which also forms a continuous frame within the carbon matrix. These ghid minerals are available in Russia. For example, it can be purchased in an area called Kareliya, Russia.

Fullerene is a carbon isomer, such as graphite or diamond. However, because fullerene has a different structural form than graphite or diamond, it is usually referred to as the third carbon isomer.

Fullerene has a carbon ring in which carbon (C) atoms are arranged in a pentagonal or hexagonal shape. These carbon rings are combined in a substantially spherical shape to form a hollow. Generally, fullerene has a C ₆₀ to C ₈₀ or greater carbon number. Further, the fullerene has a shape of a soccer ball in its structural form, or a shape of a sphere similar to a soccer ball, and has a hollow structural characteristic.

Fullerene has excellent physical and chemical properties due to the above-mentioned carbon ring arrangement and specific structure of the hollow. Specifically, fullerene has many useful physical and chemical properties such as strong antioxidative, adsorptive, catalytic (decomposition of adsorbed material), germicidal power, electromagnetic wave absorptivity, electrical conductivity, and in some cases higher than diamond Its application value is high.

Generally, fullerene is synthesized and produced artificially by using arc discharge method or continuous combustion method using carbon black or graphite as a raw material. However, such an artificial synthesis method has a problem that the price of the fullerene itself is very high and the productivity is low because of the cost of the raw material or complicated production process. Therefore, it is difficult to apply artificially synthesized fullerene as a soil agent for agriculture, that is, a fertilizer or a soil improvement agent because it is too expensive.

However, according to the present invention, when it is extracted from natural minerals, i.e., gut minerals, it can be mass-produced at low cost. The present invention effectively extracts and obtains fullerene from such gut minerals and applies it as a soil agent. Further, the silicon material contained as a main component in the gut mineral is extracted and obtained, and the silicon silicate is applied as an environmentally friendly silicate fertilizer.

The gad minerals contain silicon as the main component and contain a large amount of fullerene as the carbon component, as described above. In addition,? Gide minerals contain a variety of minerals that are beneficial to plant growth and soil improvement, albeit in trace amounts. The gut minerals contain various minerals that are beneficial for the growth of plants such as Ca, K, Na, Mg and Fe and for soil improvement. According to the present invention, the components such as carbon components such as fullerene, silicon, and minerals are extracted from the gut minerals to nanoscale, and they are water-soluble. As a result, it quickly penetrates (absorbs) plants and soil, maximizing the effect.

In the present invention, fullerene is extracted from a gut mineral, and has a carbon ring in which carbon atoms are arranged in a pentagonal or hexagonal shape. These carbon rings may be combined to form a hollow, The number is not limited. That is, in the present invention, fullerene includes fullerene-like having a carbon number smaller or larger than that of a common fullerene having a carbon number of C ₆₀ to C ₈₀ . Herein, the like fullerene means a carbon number smaller or larger than the generally specified fullerene (e.g., fullerene having a carbon number of C ₆₀ to C ₈₀ ). As described above, carbon rings are combined to form a hollow If so, include it here.

In the present invention, the fullerene may have, for example, a carbon number of C ₂₀ to C ₁₅₀ , but is not limited thereto. Further, in the present invention, in the structural form thereof, the fullerene has a hollow structure, and may have various shapes such as a soccer ball, a rugby ball, or a sphere of a similar shape, or a polyhedron.

According to the first step, the grit minerals are crushed to an appropriate size. The grit minerals can be ground by widening the surface area, which can improve the extraction rate of carbon and silicon in the extraction process. The gut minerals can be ground to a size of, for example, 500 탆 or less. The gut minerals can be ground to a specific example having an average particle size of 0.5 to 300 mu m. At this time, if the particle size of the gut mineral is too small, it may be difficult to handle, and if it is too large, the extraction rate of the carbon component and silicon may be lowered. Taking this into account, it is recommended that the ground minerals be ground to have an average particle size of 5 to 150 μm. That is, when the? -Thread mineral has an average particle size of 5 to 150 占 퐉, the handling property is advantageous, and the extraction ratio of the carbon component and silicon can be effectively improved.

The pulverization method is not limited. The pulverization method can be selected from a variety of methods commonly used in the field of powder technology. The pulverization can be carried out by a method such as a ball mill, an attrition mill, a jet mill, a rotary mill and a vibration mill, But is not limited thereto.

Further, according to an exemplary embodiment of the present invention, the pulverized? -Gut minerals can be selected. That is, the first step may further include a grinding process for grinding the gut minerals, and may further include a sorting process for sorting the grinded gut minerals having an appropriate size range. At this time, the pulverized? -Gut minerals can be selected to have an appropriate particle size distribution through a sorting process such as sieving, for example. Natural minerals can be selected and used after grinding to have an average particle size of, for example, 0.5 to 300 탆, preferably 5 to 150 탆, more preferably 10 to 60 탆, as described above.

(2) Extraction (second step)

The carbon component and silicon are extracted from the ground grit minerals. The extraction uses an alkaline solution extraction process using an alkali solution. Specifically, the extraction includes a step of mixing and heating the? -Gut mineral and the alkali solution. At this time, the alkali solution extraction step may be carried out while heating and stirring using a heating stirrer, or by using a high-temperature extruder such as an autoclave. By this heat extraction, the carbon component and the silicon contained in the gut mineral are extracted. That is, the gut minerals are separated into at least a carbon component and a silicon substance by heating extraction using an alkali solution. More specifically, the gut mineral is separated into a carbon component (fullerene) and silicate (alkali silicate) by an alkali solution. In other words, the silicon component, which is the main component of the gut minerals, is dissolved in the alkali solution, and the carbon component (fullerene), silicate (alkali silicate) and other trace minerals are dispersed in the solution.

The heating temperature in the extraction step is not limited as long as it is a temperature at which the carbon component and the silicon compound can be extracted from the gut minerals. Upon extraction, the heating temperature may be, for example, 100 to 300 占 폚. The heating time is not particularly limited, but may be, for example, a time until the liquid component (water or the like contained in the alkali solution) is almost volatilized and almost all of it becomes a solid component. More specifically, in the case of using a heating stirrer, the reaction can be carried out by heating and stirring at a temperature of 100 to 130 ° C for 5 to 25 hours. When a high-temperature extruder such as an autoclave is used, it may be heated at a temperature of 200 to 250 ° C for 2 to 4 hours to proceed. When proceeding to such a temperature and time range, it is advantageous in the extraction ratio of the carbon component and the silicon and the energy efficiency.

In the extraction step, the mixing ratio of the gut mineral and the alkali solution may be, for example, a weight ratio of 1: 0.2 to 30. That is, the weight ratio of? Gide mineral: alkali solution = 1: 0.2 to 30 can be obtained. At this time, if the amount of the alkali solution to be used is too small, the extraction rate of the carbon component and the silicon material may be lowered, and if too much, the synergistic effect of excessive use may be insufficient. Considering this point, the gad minerals and the alkali solution can be combined by heating at a weight ratio of 1: 1 to 20, more specifically 1: 8 to 20, and the mixture can be heated and extracted. In another specific example, when the mixture is heated to a temperature and a time range as described above using a heating stirrer, the mixture may be heated and extracted at a weight ratio of 1: 1 to 5, and may be heated and extracted using a high-temperature extruder such as an autoclave When the reaction proceeds in the temperature and time ranges as described above, the reaction mixture may be heated and extracted in a weight ratio of 1: 1 to 10.

The alkali solution is not limited as long as it is a solution containing an alkali substance, and it can be selected from an aqueous alkali solution having a concentration of 5 to 60% by weight, for example, containing 5 to 60% by weight of an alkali substance in the total weight of the solution. More specifically, the alkali solution may have a concentration of 10 to 30% by weight. At this time, the concentration of the alkali solution and the kind of the alkaline substance can be determined according to the type of the inorganic substance or impurity constituting the gut mineral, and the amount thereof.

The alkali substance constituting the alkali solution has a molecular formula of, for example, M _a (OH) _b , wherein M can be selected from metal elements. The M may be at least one selected from K, Li, Na and Ca, for example, and a and b are according to stoichiometry. The alkali substance may be at least one selected from among KOH, LiOH, NaOH and Ca (OH) ₂ , preferably KOH or LiOH, or a mixture of KOH and LiOH. The KOH and LiOH have a high separation and extraction ratio with respect to the carbon component and the silicon of the gut mineral, and are useful in the present invention. That is, KOH and LiOH can effectively dissolve silicon (silicate, etc.), which is the main component of the gut minerals, to increase the extraction ratio of carbon component and silicon.

When a mixture of KOH and LiOH is used as the alkali substance, they may be mixed in a weight ratio of 1: 1 to 10. That is, they can be mixed and used in a weight ratio of KOH: LiOH = 1: 1 to 10. In this case, the extraction efficiency of the carbon component and silicon is very effective.

According to a preferred embodiment of the present invention, the alkaline solution preferably contains at least KOH. That is, a KOH solution may be used as the alkali solution, or a solution in which KOH is mixed with another alkali material (LiOH). In this case, potassium silicate (K ₂ SiO ₃ ) or the like which is beneficial for plant growth can be naturally obtained while the extraction ratio of the carbon component and the silicon quality can be increased. That is, potassium silicate (K ₂ SiO ₃ ) or the like can be obtained by reaction of KOH contained in the alkali solution and the silicon compound contained in the?

When the grinding (first step) and extraction (second step) as described above are carried out, a concentrate (extract) containing a carbon component (fullerene) and a silicon compound is obtained from the gut mineral. And the concentrate contains a trace amount of natural minerals. Such concentrates are used as soil formulations in accordance with the present invention. At this time, when the concentrate is applied to the soil, it can be used after being extracted or powdered by drying. In addition, when the concentrate is applied to a soil, it can be applied to soil by a method in which it is diluted with water and sprayed in liquid phase. The resulting concentrate, that is, the carbon component (fullerene), silicon and minerals, is water-soluble and has a nano-size. As a result, the penetration of plants and soil is rapid, which is very effective in promoting plant growth and improving soil.

In addition, when the above-mentioned silicon material containing KOH is used as an alkali solution, for example, a large amount of potassium silicate (K ₂ SiO ₃ ) or the like is contained. Accordingly, the obtained silicon is usefully used as a silicate fertilizer. Silicate fertilizers such as potassium silicate (K ₂ SiO ₃ ) are very effective for plant growth and soil improvement as well known.

In addition, almost all of the carbon component obtained is fullerene. As mentioned above, fullerene has many useful physical and chemical properties such as strong antioxidative, adsorptive, catalytic (adsorbed material decomposability), and sterilizing ability due to a specific structure such as carbon ring arrangement and porosity. At this time, fullerene is applied to the soil to provide a strong antioxidant action, which can prevent oxidation in the soil, and has a cleansing ability for adsorbing and decomposing harmful substances and a plant capable of sterilizing harmful bacteria. Fullerene is thus applied to the soil, which promotes plant growth and improves the soil effectively.

According to another exemplary embodiment of the present invention, the method may further include a separation step (step 3) of separating the extracted carbon component from the silicon compound. That is, the method may further include a step of separating only the carbon component from the concentrate (extract), or isolating the silicon only.

The separation step may take various forms as long as it can separate the carbon component and the silicon extracted through the extraction process as described above from the concentrate (extract). The separation process may be performed by, for example, filtration through a filter or high-speed separation using a centrifugal separator. Through this separation process, a carbon component and a silicon compound can be obtained, for example, from the extract, respectively.

In addition, the carbon component and the silicon compound obtained through the separation step may be separately used as a soil agent. In addition, when only the carbon component is separated and removed from the concentrate (extract) through the separation step, the remaining extract is used as a soil agent. At this time, the remaining extract contains a large amount of silicon and a small amount of minerals such as potassium silicate (K ₂ SiO ₃ ), which is useful as a soil preparation. The separately produced carbon component may be used for other purposes than the soil component, as the case may be.

According to the present invention described above, an eco-friendly soil agent useful for promoting the growth of plants and improving the soil can be easily extracted and supplied from the soil minerals, that is, the soil agent containing the carbon component (fullerene) and silicon. The carbon components (fullerene) and silicon are nano-sized and water-soluble, and penetrate into plants and soils rapidly, which is very effective in promoting plant growth and improving soil.

Further, according to the present invention, high productivity and economical efficiency can be achieved, and it can be supplied at low cost. That is, in the case of fullerene, in comparison with a conventional artificial synthesis method, low-cost gut minerals (natural minerals) are used as raw materials, and a large amount of such gut minerals can be used, And have high productivity and high economical efficiency because they are obtained through treatment (pulverization) and chemical treatment (heat extraction). And because it is economical and eco-friendly, it can greatly contribute to environmentally friendly agriculture.

In addition, in the present invention, the fullerene includes a common fullerene having a carbon number of C ₆₀ to C ₈₀ , as well as a pseudo-fullerene having a carbon number smaller or larger than the above, as described above. That is, in the present invention, the fullerene may be extracted and separated from the gut minerals and may include, for example, a variety of fullerenes having a carbon number of C ₂₀ to C ₁₅₀ . More specifically, in the present invention, the fullerene is a fullerene is mixed with such a fullerene mixture containing the fullerene in a variety of carbon, carbon atoms, for example _{C 55, C 60, C 70} , C 74, C 93, C 112 Lt; / RTI >
