Hereinafter, the present invention will be described in detail with reference to specific examples.

The method for producing an aqueous paint having a far-infrared ray radiation function according to the present invention is characterized in that, in the production of an aqueous paint, (1) the raw material of a serpentine rock is washed, the washed raw material is pulverized and adjusted to have an average particle diameter of 250 to 350 μm A preprocessing step of performing classification; (2) a centrifugal separation step for removing the insoluble matter from the classified raw materials obtained in the pretreatment step using a conventional cyclone centrifuge, followed by drying the raw material from which the insolubles have been removed; (3) 6 to 10 parts by weight of hornblende and 1 to 3 parts by weight of zirconium silicate are mixed with 80 parts by weight of the raw material having been subjected to the yarn removing step, and then calcined at a temperature of 1150 to 1300 DEG C, A firing step of obtaining a far-infrared ray radiator powder; (4) a nano-powdering step of obtaining nanoparticles having an average particle diameter of 0.1 탆 using a far-infrared emitter powder obtained in the above-described sintering step by using a rapid expansion of supercritical solution (RESS); (5) Into 100 parts by weight of the nano-particles obtained in the nano-powdering step, 8 to 12 parts by weight of titanium oxide, 20 to 25 parts by weight of talc, 2 to 3 parts by weight of an emulsifier, 10 to 20 parts by weight of a dispersant, ammonia water, 0.1 to 0.5 parts by weight of stabilizer 2-3 parts by weight of calcium carbonate powder (CaCO ₃₎ 8 to 12 parts by weight, a preservative from 0.1 to 0.3 parts by weight of ethylene glycol from 0.8 to 1.2 parts by weight of a solid content of 0.2 to 0.3% by weight of acrylic 40 to 50 parts by weight of a resin emulsion and 80 to 150 parts by weight of water as a solvent to obtain an aqueous paint.

The pretreatment step (1) is performed by cleaning the serpentinite ore as a raw material, pulverizing the washed raw material, and classifying the raw material so as to have an average particle diameter of 250 to 350 탆. This preprocessing step is performed in order to perform a subsequent repulsion removal step. By washing in the pretreatment step, a large amount of organic impurities such as salts, bacteria and corrosive substances contained in the mined gemstones are removed. Since the material particles classified in the above are hydrolyzed in the undifferentiated stage, the particle size becomes much smaller (about 1 탆 or less) than that of the pulverized and classified particles, and the surface area is remarkably increased. In general, the surface area of fine particles is inversely proportional to the square of the particle size, so that the surface area is increased about 9 times before hydrolysis. In addition, the water thermal decomposition is such that the raw material particles are expanded and contracted while being heated and cooled, so that the pulverized form is irregular, the surface roughness is high, and the surface area is remarkably increased compared with the particles having the same particle diameter produced by the heating method. In addition, since the dried particles after the undifferentiated particles have a larger adhesion force than the repulsive force, they have a characteristic of being easily flocculated, so that particles of the undifferentiated material may be coagulated again in actual use, It is necessary to incorporate an additional anti-coagulation agent into the water vapor introduced into the raw material particles. Examples of the anti-aggregation agent include a hydrochloride stabilizer which is diluted with an organic solvent such as alcohol and which prevents the pyrolysis of the unsaturated fatty acid, and a small amount of a stabilizer of iron chloride is added to the diluted hydrochloric acid stabilizer. The added iron chloride stabilizer is an unsaturated fatty acid This fine oil film is formed to serve as a surfactant and plays a leading role in preventing aggregation of undifferentiated particles. As a result, the surface area and the surface roughness of the material in the state where the fine powder and the cohesive force are removed are significantly increased compared with the particles by the conventional method, and the radiant intensity of the far-infrared radiation amount and the anion is very high, Far-infrared radiation efficiency is greatly increased.

The removal step of (2) above is to remove the TiO ₂ Zr, which has a short wavelength of the far-infrared rays, does not emit anions, has a low strength and a large specific gravity, . The elimination of yarn can be performed by centrifugation using a specific gravity difference. In particular, a commercially available centrifuge such as a cyclone centrifuge may be used for centrifugation. The centrifugal separator is used for concentrating, removing, and refining cryptomeric melts. Suspended particles with a density higher than that of the suspension tend to spread to the edge, while those with a lower density gather to the center. The movement depends on the strength of the circular heart, the density difference between the particles and the suspension, the viscosity of the liquid, the size and shape of the particles, and to some extent, the concentration and charge of the particles. The power applied to the particles is the difference between the buoyancy and the reaction of the original heart and liquid acting on the particles. If the centrifugation is continued until the particles are poured into the outer wall of the rotator of the centrifuge, the suspending medium and the suspended particles are completely separated. To separate suspended particles of different sizes into two clusters, centrifuge for a long time to ensure that all large particles are fully clumped into the sediment. Such centrifuges and centrifugation methods are routinely performed, and are understood to be well understood and readily available to those skilled in the art. The cyclone centrifuge separates fine particles continuously from the liquid. For continuous separation, the raw material or material to be separated is injected at one end near the shaft, and the separated material is divided into two flows. There are many designs for the internal structure of the tube, but generally the radial blades are used to accelerate the supplied material and decelerate the separated material before discharging it. The separator is driven by a high-speed motor, where sedimentation occurs as fluid flows from one end of the tube to the other. If there are very fine particles or molecules in a heavy material, and if the concentration is very low, the solid material is mainly gathered toward the wall and separated. Such a cyclone centrifuge is well known to those skilled in the art so that it can be commercially supplied and used easily.

After removing the particles, the particles are mixed with fresh water. Therefore, when the conventional polymer flocculant is added to remove moisture, the material dispersed in colloidal particles in the fresh water is aggregated Precipitated. In the precipitation step, the precipitated particles are pulverized and dried to a subsequent calcination step. Examples of the polymer flocculant include conventional anionic flocculant such as primary high alkyl sulfonate soap, sulfuric acid ester salt of higher fatty acid ester, alkylbenzenesulfonic acid salt, and naphthenic acid salt.

In the step (3), 6 to 10 parts by weight of hornblende and 1 to 3 parts by weight of zirconium silicate are mixed with 80 parts by weight of the raw material having been subjected to the yarn removing step and then fired at a temperature of 1150 to 1300 ° C., followed by pulverization with a mesh to obtain a far-infrared ray radiator powder. The raw material powder prepared above is mixed with hornblende and zirconium silicate and then fired to obtain a far-infrared ray emitter powder which emits far infrared rays having a wavelength of 4 to 20 μm over all temperatures at 0.93 or more.

In the nano-powdering step (4), the far-infrared ray emitter powder obtained in the sintering step is formed using Rapid Expansion of Supercritical Solutions (RESS), thereby obtaining nanoparticles having an average particle diameter of 0.1 탆 Lt; / RTI > The production of cercopertas mechanically pulverized to 30 탆 in nano or submicron size increases the far-infrared emissivity of the far-infrared ray emitter powder used in paint. In the present invention, it is possible to manufacture nanoparticles of far-infrared ray emitter powder using a supercritical carbon dioxide-based Rapid Expansion of Supercritical Solutions (RESS). In this method, when the state of the system is changed from the supercritical state to the normal-temperature atmospheric pressure state by the crystallization method which largely changes the phase equilibrium of the solvent solute system by changing the external requirements such as the temperature and the pressure, the supercritical fluid becomes the gas, The affinity between them is greatly reduced and solids precipitate. That is, it is called Rapid Expansion of Supercritical Solutions (RESS) in which the pressure is rapidly changed from a high pressure to an atmospheric pressure at a speed close to a sound speed. The supercritical rapid expansion method is difficult to apply to materials which are simple and inexpensive in principle or apparatus but do not dissolve in a supercritical fluid. In such a case, there is an experiment in which solubility is promoted by adding a small amount of solvent to the supercritical fluid. When the supercritical gas is chemically reacted with the reaction solvent, the physical properties such as density, polarity, and viscosity and the structure of the solvation can be continuously and freely adjusted by controlling the temperature and pressure as operating variables. , A moving speed is expected in a material having a low viscosity and a high diffusivity, and a heat transfer rate is maximized in the vicinity of a critical point, thereby obtaining a high heat transfer rate. The apparatus comprises a supercritical fluid supply part, a solute dissolving part, and a particle generation / recovery part. The solvent supplied in the solvent container is pressurized by the metering pump and becomes a supercritical fluid through the preheater. The supercritical fluid which has passed through the solute filling container filled with the solute and the solute is saturated and dissolved is ejected through a flow rate control valve or a fine nozzle (inner diameter: 10 to 50 μm), and the fine particles are precipitated. By using such a rapid expansion nozzle, continuous operation for a long time at a constant pressure and a constant flow rate can be realized, and stable generation of fine particles is possible. It is also possible to measure the temperature and pressure of the part before expansion and precise temperature control. The generated fine particles are recovered by the nanoparticle recovery device. In the production of fine particles by the supercritical rapid expansion method, many operating factors such as the temperature of the solute dissolution part and the particle generation part, the pressure, the temperature of the particle recovery part, the inner diameter, the length and the shape of the expansion nozzle influence the particle size and shape of the fine particles. However, these manipulation factors are related to the degree of supersaturation between the dissolution part of the solute and the generation part of the fine particles, the liquid state of the fluid in the fine particle part, and the hydrodynamic effect (shear force) at the solvent expansion. In the supercritical rapid expansion method, the supercritical fluid in which the solute is dissolved expands through the expansion nozzle under atmospheric pressure. In this expansion process, the phase equilibrium state between the solvent solutes changes largely with changes in temperature and pressure. The glass cell provided in the apparatus is filled with a solute, introduced with carbon dioxide adjusted to a predetermined pressure and temperature, and then subjected to a solid-liquid transition point measurement accompanied by a pressure change at a constant temperature by a sagittal observation method. In the supercritical rapid expansion method, the pre-expansion portion and the expansion nozzle are heated so as to prevent a temperature drop (Joule-Thomson effect) caused by a sudden depressurization upon injection from the nozzle. At this time, depending on the temperature and pressure of the portion before the expansion, the phase state changes into the supercritical fluid phase or vapor phase. This greatly affects the particle size and shape of the resulting fine particles. Here, the experimental conditions for the influence of the difference in the phase states of the fine particle generation portion relative to the fine particle production by the supercritical rapid expansion method are as follows: the temperature and pressure of the solute dissolution portion are set to 308.2 K and 15.0 MPa, the temperature of the fine particle recovery portion is set to 290.8 K. Under these conditions, the pre-expansion temperature was set at 314.0 K and 332.2 K (the former is a supercritical fluid phase before expansion, and the latter corresponds to vapor phase) and the results are compared. The fine particles obtained on the supercritical fluid were spherical particles, the minimum particle diameter of the primary particles was 50 nm, the average particle diameter was 280 nm, and the particle diameter distribution was also very narrow. This is a particle size at a level that can be referred to as nanoparticles, and the crystal size is very small compared with other studies. On the other hand, many of the fine particles obtained in the gas phase are difficult to distinguish the shape of the primary particles due to aggregation of the primary particles, unlike those obtained on the supercritical fluid. At this time, the minimum particle size of the primary particle is about 60 nm, the average particle diameter is 480 nm, and the particle diameter distribution is also very broad as compared with that of the initial particle fluid. In the present invention, a system using ultrahigh pressure can crush, disperse, and emulsify with nanosize that could not be obtained by conventional devices, and it is possible to manufacture composite particles, modify the surface of particles, and change the shape of particles. In the nano-powdering step, a surfactant selected from a primary higher alkylsulfonate soap, a sulfuric acid ester salt of higher fatty acid ester, an alkylbenzenesulfonic acid salt, an alkylbenzimidazole sulfonic acid salt, a naphthenic acid salt or a mixture thereof may be used .

In the paint composition step (5), 8 to 12 parts by weight of titanium oxide, 20 to 25 parts by weight of talc, 2 to 3 parts by weight of an emulsifier, 10 to 20 parts by weight of a dispersant are mixed with 100 parts by weight of nanoparticles obtained in the nano- 0.1 to 0.3 parts by weight of an antiseptic agent, 0.8 to 1.2 parts by weight of an ethylene glycol, a solid content of 0.2 to 0.2 part by weight, a stabilizer of 2 to 3 parts by weight, a calcium carbonate powder (CaCO ₃ ) of 8 to 12 parts by weight, By weight to 0.3% by weight of an acrylic resin emulsion, and 80 to 150 parts by weight of water as a solvent. By such mixing, an aqueous paint according to the present invention is obtained.

In the present invention, serpentinite, amphibole (6 to 10 parts by weight) and zirconium silicate (1 to 3 parts by weight) are calcined at a temperature of 1200 to 1250 ° C and pulverized into an average 325 mesh to obtain nanoparticles. % Or more of a far-infrared ray radiator powder prepared from a magnetic material in an amount of 5 to 20 parts by weight based on a common paint. The effect of the far-infrared ray radiator powder produced by the present invention is as follows: And after drying, the drying of the aqueous paint is quick due to the magnetic energy, and the odor around the worksite is adsorbed and decomposed. The water-based paint has strong cohesive force to prevent cracking due to internal stress and adhesion to the coating material Is improved. It is a far-infrared ray radiator powder produced by the invention of have the magnetic iron component and a barium component to form a BaO and 6Fe ₂ O ₃ in the process of firing the serpentine and amphibole and zirconium silicate at a temperature of 1200 to 1250 ℃ and some iron Fe ₂ O ₃ , and analyzed the result. As a result, 3.55% of BaO · 6Fe ₂ O ₃ and 2.62% of Fe ₂ O ₃ are contained.
