FIG. 4 is a flowchart showing a step of manufacturing the loess balls 130 of the present invention.

4, the step of preparing the loess ball 130 includes the steps of preparing the loess powder, preparing the loess dough, producing the molded loess ball 130, (130), and calcining the dried molded loess ball (130).

First, the step of preparing the loess powder is a step of preparing the loess powder by pulverizing the loess. This is a process of refining the loess particles in order to improve the formability of the loess ball 130. The method of crushing the loess can be performed by referring to the existing crushing process, and thus a detailed description thereof will be omitted.

The yellow loam dough is prepared by mixing 40 to 70% by weight of the loess powder and 30 to 60% by weight of water with respect to the total weight of the loess dough, So that it can be smoothly formed into a spherical shape.

The step of preparing the molded loess ball 130 is a process of molding the loess dough into a sphere having a diameter of 1 to 30 mm to produce the molded loess ball 130. At this time, a separate molding machine may be used to form the loess dough have.

The step of drying the molded loess balls 130 is a process of drying the shaped loess balls 130 at 100 to 120 ° C for 24 to 48 hours, wherein the drying temperature is preferably 105 ° C. The step of drying the molded loess ball 130 is performed at a low temperature and for a short time in comparison with the step of baking to be described later, so that the molded loess ball 130 can be dried and solidified.

The step of calcining the dried shaped loess balls 130 is a process of heating the dried loess balls 130 at 600 to 800 ° C for 6 to 12 hours to be baked, It is possible to provide the function of absorbing and deodorizing the foreign substances and odors generated during the foot bath by producing the ocher ball 130 having porosity.

Further, after the step of calcining the molded loess ball 130, a step of coating a water repellent coating solution on the surface of the baked loess ball 130 and forming a water repellent coating layer by drying may be further included. The water repellent coating layer 130 has a weak resistance to water, so that a water repellent coating layer having a surface coated with a water repellent coating solution containing a water repellent material as an active ingredient is further formed. The water repellent coating layer prevents the shape of the loess ball 130 from being broken by a large amount of water due to the nature of the wet foot bath 100 so that the structural stability of the loess ball 130 can be improved, 130) is formed into a dough-like shape, so that it can be prevented that the loess dust adheres to the feet during footbathing. A step of forming a water repellent coating layer that provides such a function will be described as follows.

5 is a flowchart showing a step of producing the water repellent coating solution of the present invention.

Referring to FIG. 5, a water-repellent coating solution containing a water-repellent material as an active ingredient is prepared to form a water-repellent coating layer. In order that the water-repellent material included in the water-repellent coating liquid can be an effective component of the water-repellent coating liquid, it is preferable that the water-repellent material includes 10 to 40 wt% of the total water-repellent coating liquid.

The step of preparing a water-repellent coating solution includes the steps of preparing a first solution containing methylchlorohydrosilane as an active ingredient, adding a first solution to distilled water to prepare a second solution, and adding trimethylchlorosilane as an active ingredient Preparing a fourth solution by adding a third solution to the second solution; neutralizing the fourth solution; preparing a filtrate; and drying the filtrate To produce a dried filtrate, and a step of producing a water repellent coating solution.

The first solution is prepared by mixing 40 to 60% by weight of methylchlorohydrosilane and 40 to 60% by weight of ether with respect to the total weight of the first solution, thereby preparing a first solution , Wherein methylchlorohydrosilane is a starting material useful for preparing a silicone polymer and is a reactant for producing a siloxane in the step of preparing a second solution to be described later and plays a role of imparting water repellency. The ether also acts as a solvent for methylchlorohydrosilanes.

The step of preparing the second solution is a step of adding the first solution to the water to prepare the second solution, wherein the hydrolysis reaction occurs by adding the first solution to the distilled water to synthesize the siloxane. At this time, the first solution is added dropwise to the distilled water in the separate flask to slowly cause the reaction to prevent the siloxane yield from dropping due to the explosive reaction.

The third solution is prepared by mixing 40 to 60% by weight of trimethylchlorosilane and 40 to 60% by weight of ether with respect to the total weight of the third solution to prepare a third solution, In order to synthesize the water-repellent coating solution through reaction with the second solution. When the water repellent coating agent is prepared using only methylchlorohydrosilane as an active ingredient, the water repellent coating layer formed on the loess balls 130 becomes hard, and the water repellent coating layer may be broken and damaged by an external impact. To solve this problem, trimethylchlorosilane, which imparts flexibility to the water-repellent coating layer, is added to provide a function of preventing the water-repellent coating layer from being broken by an external force. The ether added at this time also serves as a solvent for the trimethylchlorosilane.

The fourth solution is prepared by adding the third solution to the second solution and stirring the mixture for 1 to 3 hours to prepare the fourth solution. Since the reaction occurring through this step is also an exothermic reaction due to the hydrolysis reaction, The temperature around the reactor is increased. At this time, the fourth solution can be completely prepared by maintaining the temperature so that the reactor ambient temperature does not exceed 5 캜.

The neutralizing step is a step of neutralizing the fourth solution by adding acetic acid to the fourth solution so that the pH of the fourth solution is 5 to 7. The fourth solution prepared through the step of preparing the fourth solution is neutralized with the siloxane And trimethylchlorosilane as an active ingredient of the third solution.

The step of preparing the filtrate is a process of separating the neutralized fourth solution from the separating funnel and washing the filtrate with water three to five times to remove the foreign matter remaining in the fourth solution separated through the separating funnel It is for this reason.

The step of producing a dried filtrate is a process of drying a filtrate with calcium chloride (CaCl2) to produce a dried filtrate. The method of producing a dried filtrate is characterized in that the water present in the filtrate is efficiently To obtain a dried filtrate.

The water-repellent coating solution is prepared by mixing 10 to 30% by weight of dry filtrate, 50 to 70% by weight of ethyl ether and 1 to 20% by weight of isopropyl alcohol with respect to the weight of the entire water-repellent coating liquid, The ethyl ether serves as a solvent for the dried filtrate containing the silane-based polymer as an active ingredient. The isopropyl alcohol is added to the water-repellent coating solution when the water-repellent coating solution is applied to the surface of the loess- So that the water-repellent coating solution can penetrate well.

The water repellent coating solution can be formed by applying the water repellent coating solution thus prepared to the surface of the loess ball 130 and drying the coating. This is because the characteristic feature of the wet foot bath 100 of the present invention is that the loess ball 130 is dissolved in water to prevent the loess ball 130 from functioning properly in an environment of high humidity or in direct contact with water .

Further, since the water-repellent coating layer is formed, it is possible to prevent the loess ball 130 having low resistance to water from being broken by the water, thereby securing the structural stability of the loess ball 130.

6 is a flow chart showing steps for producing the solidified solution of the present invention.

6, in addition to the improvement in the structural stability of the loess ball 130 by the water-repellent coating layer described above, the loess ball 130 is more agglomerated when the loess ball 130 is manufactured, It is possible to add the function of reinforcing the structural stability of the loess ball 130 by further making it harder. In order to perform such a function, a step of preparing a solidified solution capable of further increasing the degree of cohesion of the loess balls 130 manufactured through the steps of improving the cohesion of the loess and performing the baking treatment before the step of producing the loess balls 130 May be further included.

The step of preparing a solidified solution comprises the steps of preparing a primary solution containing chitin as an active ingredient, forming a precipitate, neutralizing, preparing a secondary solution by adding formic acid, And mixing the wood vinegar solution to complete the solidified solution. In order for the chitin contained in the solidified solution to be an active ingredient of the solidified solution, it is preferable to include 10 to 30 wt% of chitin relative to the total weight of the solidified solution.

To prepare the first solution, the first solution is prepared by mixing 30 to 70% by weight of chitin and 30 to 70% by weight of sodium hydroxide with respect to the total weight of the first solution, and then mixing the solution at 150 to 200 ° C for 4 to 6 hours And then heating it to prepare a primary solution.

Chitin is a natural polymer polysaccharide with a structure similar to cellulose, which is a polymer compound, and has a structure in which nitrogen (N), which is a special component of protein, is added to the skeleton of cellulose. At this time, sodium hydroxide is added in order to remove the acetyl group contained in the chitin, wherein the phase of sodium hydroxide may be a liquid phase or a solid phase. In addition, excessive hydrolysis of chitin can be suppressed by adding sodium hydroxide. Through this process, the acetyl group of chitin is removed and chitosan is produced. The primary solution containing chitosan as an active ingredient (in this case, the primary solution may contain chitin at a ratio of 10 to 30%), The solidified solution to be manufactured plays a key role in improving the cohesion degree of the loess ball 130.

Next, the step of forming a precipitate is a step of forming a precipitate by adding ethanol to the primary solution, wherein a precipitate containing chitosan as an active ingredient is formed by adding ethanol to the primary solution, As a component of the lye, it is a process performed to remove only the sodium hydroxide which is harmful to the human body and to obtain only the precipitate containing chitosan as an active ingredient.

The subsequent neutralization step is a step of neutralizing the precipitate by washing with water several times, which is a step for washing the sodium hydroxide present in the precipitate. That is, since sodium hydroxide has a property of dissolving proteins, it is a substance that causes skin damage when it is exposed to human body. Therefore, it may be said that removing sodium hydroxide added while preparing the primary solution is preferable for producing a solidified solution.

Next, the step of preparing the secondary solution is a step of preparing a secondary solution by adding 0.1 to 1% by weight of acetic acid to the neutralized precipitate to the total weight of the secondary solution. This is because sodium hydroxide remaining in the neutralized precipitate is dissolved in acetic acid So as to further secure the physical safety of the user of the wet bathtub 100 of the present invention. Furthermore, sodium hydroxide can be removed through other kinds of acids while preparing the second solution. However, since acetic acid remaining in the preparation of the second solution does not have a great influence even when it comes into contact with the human body, acetic acid is added .

The step of completing the solidification solution is a step of preparing a solidified solution by mixing 30 to 70% by weight of the secondary solution with 30 to 70% by weight of the woody solution, based on the total weight of the solidified solution, The secondary solution still contains chitosan as an active ingredient and mixing this secondary solution with wood vinegar can produce a natural polymer organic coagulant which is generally added to the wastewater treatment to be.

At this time, the mixed wood vinegar is one of natural extracts, which is produced in the carbonization process of wood, having pH of 2 to 3 and mostly composed of water, and the rest is composed of organic compounds (organic acids, alcohols, phenols, etc.). In addition, the vinegar has been used as a food additive for the purpose of antibacterial, antiseptic, antioxidative effect and flavor improvement. The solidifying solution containing such a vinegar solution as an active ingredient has an antibacterial and sterilizing action and a deodorizing function of the loess ball 130 To be performed.

The coagulant prepared by mixing the wood vinegar and chitosan having the above properties is more excellent in coagulation action than the other coagulants, so that the effect of increasing the hardness of the loess ball 130 can be expected even if only a small amount of the solidification solution is added.

Fig. 7 is a flow chart showing the step of producing the adsorbent material of the present invention.

7, the vinegar solution may contain an adsorbing substance as an active ingredient. The vinegar solution can be purified by further containing an adsorbing substance in the vinegar solution, and the odor-inducing substance can be adsorbed to maximize the deodorizing effect have. At this time, the adsorbent material included in the vinegar solution may contain 5 to 30% by weight of the adsorbent material with respect to the total weight of the vinegar. If the adsorbent material is present in an amount of less than 5% by weight, the purification function and the adsorption function can not be sufficiently performed. The useful components contained in the vinegar solution are all refined so that the germicidal action and the deodorizing function of the vinegar solution can not be sufficiently exhibited, so that it is preferable that the adsorptive substance comprises 5 to 30% by weight.

The manufacturing method of the wet foot bath (100) of the present invention may further include the step of manufacturing an adsorbent material that provides such a function, wherein the step of preparing the adsorbent material comprises firing a powder mixture comprising silica, lime, alumina A step of producing an extractive liquid, a step of producing a silicate liquid, a step of obtaining a crystalline material, a step of drying the crystalline material, a step of producing a carbide, and a step of producing an adsorbent material have.

The step of calcining the powder mixture comprising silica, lime and alumina first comprises, by weight of the total powder mixture, from 40 to 70% by weight of silica, from 10 to 30% by weight of lime, from 10 to 30% by weight of alumina, To prepare a powder mixture, followed by calcining at 600 to 800 ° C for 1 to 2 hours.

The silica, lime, and alumina constituting the powder mixture are substances including silicon, calcium, oxygen, and aluminum, and are starting materials for producing adsorbent materials described later.

At this time, the powder mixture is calcined to form fine pores in the powder mixture to perform the adsorption function.

Next, the step of preparing the extract is performed by mixing 40 to 80% by weight of the calcined powder mixture and 20 to 60% by weight of 4N sodium hydroxide with respect to the weight of the whole extract, Lt; / RTI > to prepare an extract.

This is because sodium hydroxide is added to the powder mixture to extract and remove the silicon and aluminum contained in the powder mixture, and the silicon and aluminum interfere with the adsorbing material to be formed through the process described below. The adsorbent material performs an adsorption function by forming a large number of pores and introducing a malodorous substance into the pores. Silicon and aluminum are present in the pores and deteriorate the adsorption function. Therefore, by extracting silicon and aluminum through the step of producing an extract, the adsorption function can be further improved.

Thereafter, the step of preparing the silicate liquid comprises filtering the extracted liquid to prepare a filtrate, mixing 10 to 90% by weight of the filtrate with 10 to 90% by weight of sodium aluminate based on the weight of the total silicate liquid to prepare a silicate liquid .

At this time, the filtrate removes silicon and aluminum from the powder mixture and contains sodium hydroxide. While sodium aluminate is added to the filtrate, sodium hydroxide provides the function of stabilizing sodium aluminate. Sodium aluminate may also function as a coagulant to make the state of the silicate solution prepared in the case of mixing with the filtrate into a gel state.

Next, in a step of drying the crystal phase and crystal water to give the water is determined by the crystallization at 60 to 100 ℃ under 1 to 10kg _f / cm ² pressure and then aged at 100 to 200rpm in the silicate solution from 20 to 30 ℃ Water, and washing the crystal with water three to five times, followed by drying at 100 to 150 DEG C for 6 to 24 hours.

At this time, the process of aging the silicate solution is to sufficiently mature the silicate solution, and the reason for washing the obtained crystalline material is to remove residual sodium hydroxide. The thus-formed crystals can perform an adsorption function, but in order to further enhance the adsorption function, the crystals are dried and then activated through a carbonization process, which will be described later.

The step of producing carbide is a step of carbonizing the dried crystalline material by injecting nitrogen at 10 to 30 L / min while performing primary carbonization at 500 to 800 ° C for 10 minutes to 1 hour.

At this time, if the crystalline material is carbonized in the oxygen atmosphere, the crystalline material is burnt and the adsorbable material can not be obtained. To prevent this, nitrogen is injected at 10 to 30 L / min.

Next, the step of producing an adsorbent material is a step of secondary carbonization of the carbide at 700 to 900 DEG C for 30 minutes to 4 hours to produce an adsorbent material.

This is the step for activating the carbide, where steam can be used as the activator. Also, during the secondary carbonization of the carbide, water vapor may be injected at 25 to 70 wt% of the total weight of the carbide to produce an adsorbent material with sufficient activation.

The adsorbent material thus prepared can remove foreign matters and light oil matters present in the wood vinegar solution and adsorbs the odor-inducing substances generated while using the wet foot bath 100 of the present invention to perform the deodorizing function, The sterilizing action and the deodorizing function can be further maximized.

The solidified solution prepared through this process is based on chitin and wood vinegar which are nontoxic natural polymers and since they are widely distributed on the earth, they can not only provide a rich amount but also have a loess bowl It can be said that it is preferable as a material that can be added in the production of the loess ball 130 for the solidification of the loess ball 130.

Further, the solidified solution prepared as described above can be mixed with the loamy dough to produce harder loess balls 130 when producing the loess dough. Specifically, the loess dough may be prepared by mixing 50 to 70% by weight of loess powder, 10 to 40% by weight of a solidifying solution, and 10 to 20% by weight of water, based on the total weight of the loess dough.

At this time, the weight ratio of the solidifying solution can be adjusted according to the degree of solidification of the loess ball 130, and the weight ratio can be adjusted in order to dilute the solidifying solution according to the degree of solidification of the loess ball 130, .

The loess dough produced as described above can be produced by coagulating the loess ball 130 through the steps of manufacturing the molded loess ball 130, drying and baking. The water repellent coating layer may be formed on the surface of the loess ball 130 having a high level of aggregation so that the structural stability of the loess ball 130 as well as the resistance to water can be increased.

8 is a flowchart showing a step of forming an elastic layer on the net 140 of the present invention.

Referring to FIG. 8, the wet foot bath 100 of the present invention is a mechanism for allowing a foot to be put in the wet bathtub 100 directly by the foot, and at the same time, 130 may be damaged. Therefore, in order to avoid such a possibility as much as possible, an elastic layer is additionally formed in the net 140 containing the plurality of loess balls 130, thereby significantly reducing the possibility of damaging the loess ball 130, 140) is also lowered.

The step of forming the elastic layer in the mesh 140 may include a step of preparing a coating agent containing an effective component of rubber resin and a step of applying a coating agent to the mesh 140 to form an elastic layer. In order that the rubber resin included in the coating agent can be an effective component of the coating agent, it is preferable that the rubber resin contains 10 to 60% by weight of the total amount of the coating resin. Hereinafter, the step of preparing the coating agent will be described in detail.

The step of preparing the coating agent includes mixing carbon fiber powder, zinc oxide, plasticizer, aromatic oil, stearic acid and antioxidant in an NBR solution, and stirring the mixture for 1 to 10 minutes to prepare a resin mixture, Adding and heating and mixing to prepare a crosslinked product, adding a crosslinking accelerator to the crosslinked product, and mixing the resulting mixture for 1 to 10 minutes to prepare a coating agent.

To describe each step in detail, the step of preparing the coating agent is carried out by first mixing carbon fiber powder, zinc oxide, aromatic oil, stearic acid and antioxidant in an NBR solution and then stirring for 1 to 10 minutes to prepare a resin mixture 40 to 60 wt% of the NBR solution, 30 to 50 wt% of the carbon fiber powder, 1 to 10 wt% of the zinc oxide, 1 to 10 wt% of the aromatic oil, 1 to 10 wt% of the stearic acid 1 To 10% by weight of an antioxidant and 1 to 10% by weight of an antioxidant, and then stirring the mixture for 1 to 10 minutes to prepare a resin mixture.

NBR (Nitrile butadiene rubber) is a synthetic rubber resin which is a main material of a coating material to be produced through the following process, and has elasticity, heat resistance, oil resistance and processability. The net 140 having the coating layer containing the NBR as an active ingredient functions to easily absorb external force and external impact due to the elasticity of the NBR.

The carbon fiber powder serves as a filler for the resin mixture, and the strength of the coating layer can be further enhanced by the carbon fibers having strong physical properties due to the unique molecular arrangement structure.

Zinc oxide serves as the activator of the zeolite powder in preparing the resin formulation, and the stearic acid serves as a lubricant. Further, the aromatic oil not only serves to increase the processability and flexibility of the NBR solution as a plasticizer, but also can provide an effect of providing a fragrant smell while using the wet foot bath 100 of the present invention.

At this time, the mixing time is preferably 3 to 8 minutes, more preferably 6 minutes to prepare a resin mixture.

Thereafter, a step of adding a crosslinking agent to the resin mixture, followed by heating and mixing to produce a crosslinked product, is carried out. Specifically, 0.1 to 1% by weight of a crosslinking agent is added to the total weight of the resin mixture, Thereby producing a crosslinked product.

The crosslinking agent to be added at this time is one containing sulfur as an active ingredient and functions to form crosslinked bonds of the resin mixture to form a denser molecular structure. Further, since the melting point of sulfur is 108 ° C, it is preferable to set the heating temperature at 110 to 150 ° C for dispersing the sulfur in the crosslinking agent.

Next, a step of adding a crosslinking accelerator to the crosslinked material and mixing the mixture for 1 to 10 minutes is followed to produce a coating agent. Specifically, 0.1 to 10% by weight of the crosslinking accelerator is added to the total weight of the crosslinked material, For 10 minutes to prepare a coating agent.

This step is a step of additionally crosslinking the NBR which has not undergone crosslinking in the step of preparing the crosslinked product, wherein the crosslinking accelerator added at this time is any one of TAIC (Triallyl isocyanurate), TMTD (Tetramethyl thiuram disulfide) and CBS (Cyclohexyl benzothiazole sulfenamide) can do. Through this process, a coating having a stronger molecular structure than that of the crosslinked material is prepared, thereby providing a function of minimizing the damage of the net 140 to which the coating agent is applied.

The coating material may be applied to the mesh 140 to form an elastic layer on the surface of the mesh 140. The elastic layer thus formed can absorb the external force and the external impact applied to the net 140 while using the wet foot bath 100 of the present invention to maintain the shape of the plurality of loess balls 130 contained in the net 140 Thereby preventing the network 140 from being damaged and extending the service life of the network 140.

As described above, the construction and operation of the method for manufacturing a wet type foot bath using the loess according to the present invention are described in the above description and drawings, but the present invention is not limited to the above description and drawings And it is to be understood that various changes and modifications may be made without departing from the spirit of the invention.
