In general, expensive natural marble or granite has been widely used as an interior decoration and / or an exterior finish of a building for the purpose of giving a luxurious style to a building. Such natural marble or granite has various kinds of beautiful colors and patterns So that it creates an atmosphere with high ornamental quality and high quality feeling.

However, the interior and / or exterior finishing of buildings using natural marble or granite is not only expensive but also heavy, requiring a lot of transportation and construction costs.

Therefore, as one of the economical methods for enhancing ornamental and / or decorative finish of a building, there has been proposed an artificial marble such as natural marble or granite, an underwater type, an underwater type or an emulsion Numerous colorful patterned paints of numerical type have been proposed.

In general, a multi-pattern paint is a paint in which the oil-based paint is dispersed in the form of particles in an aqueous solution. Oil-based particles of various colors are dispersed in one aqueous solution. Usually, the ratio of aqueous solution: 6: 4, and the coating area range depends on the amount of the oily particles to be mixed because the oily particles exhibit the hiding power in the color pattern paint.

Here, the underwater type multi-pattern paint is produced by dispersing the organic solvent in the aqueous phase, which is an external phase, and contains a considerable amount of organic solvent, which is harmful to the human body due to volatile organic compounds, .

In order to solve the disadvantages of such a watercolor type multi-patterned paint, an emulsion watercolor pattern paint has been proposed. An emulsion watercolor pattern paint prepared by dispersing an aqueous gel as an internal phase on an emulsified sol as an external phase is a volatile Although the organic compound content is low, it is less harmful to the human body and has an excellent storage stability. However, it is difficult to control the viscosity by using a double nozzle gun which is a special gun for painting and it is difficult to form a uniform pattern pattern.

Accordingly, the present applicant has been granted Patent No. 10-1700640 as a part of the present invention in order to improve it.

However, as the desire of consumers has become more diverse and the competition between companies has become more intense, there has been a demand for further improved technology. Further, if the adhesion force of the coating surface is weak, maintenance period due to lifting, The reinforcement of shortened shortcomings was also required.

In addition, due to the appearance of functional coating materials, there has been a need to further enhance water repellency and moisture resistance, and further enhance antioxidant and antimicrobial properties to enhance competitiveness.

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

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

First, a method for producing an aqueous colored patterned coating composition according to the present invention comprises: preparing an aqueous gel; A water-based, multicolor paint containing pearl; A step of forming a paint particle; Glitter mixing step.

At this time, the water-gel producing step is a step of preparing a water-based gel to improve the stabilization of paint and coating film and the painting workability by mixing with water-color pattern paint.

Herein, the water-soluble gel is an insoluble solvent which functions to prevent the water-coloring paint of different colors from being dissolved and mixed with each other when mixed with water coloring paint of two or more colors to be described later, The water-based multicolor paint forms a multicolor particle shape and maintains the multicolor particle shape.

The step of preparing the water-based gel comprises a first step of producing a synthetic silica thickener, a second step of producing an anti-settling agent for a water-soluble particle, and a third step of making a water-based aqueous gel using a synthetic silica thickener and a water-soluble particle settling inhibitor.

Wherein the first step of making the synthetic silica thickener is to add a synthetic silica thickener consisting of 1-2% by weight of tetrasodium pyrophosphate, 0.01-0.2% by weight of defoamer, 10-20% by weight of synthetic silica, It is the process of composition.

In this case, the sodium pyrophosphate is hydrolyzed in water to be a second sodium pyrophosphate, which forms a complex with the cation in the synthetic silica thickener to control the gelation of the aqueous solution and to control the viscosity constantly to form the pattern of water- And also contributes to improvement of the storage stability of the coating composition according to the present invention as a pH adjusting agent.

Particularly, the metal ions included in the paint are sealed to prevent problems such as lowered whiteness, pinholes, discoloration, and dispersion inhibition caused by these.

If the amount of the sodium pyrophosphate added is less than 1% by weight, the viscosity may become excessively high. Conversely, if the amount exceeds 2% by weight, the viscosity may be excessively lowered. .

The antifoaming agent is added to prevent the formation of bubbles in the paint, and conventional silicone emulsions, surfactants or higher alcohols may be used.

In addition, the synthetic silica is added to increase transparency while improving turbidity, to improve dispersibility, but also to improve flexibility and prevent scratching and impact.

These synthetic silicas produce primary solids silica sol when the silicic acid is added to the acid, and the silanol groups (Si-OH) present on the surface of the primary particles are subjected to a rapid dehydration condensation reaction by the continuous addition of acid And a network of Si-O-Si is formed to promote the formation of a silica gel having a three-dimensional network structure.

In the present invention, a silica hydrogel obtained by reacting sodium silicate with sulfuric acid is synthesized, washed with water, dried, and then pulverized.

Therefore, if the addition amount is less than 10% by weight, the turbidity becomes worse, the dispersibility becomes worse, and the resistance to scratch and impact is lowered. If the addition amount exceeds 25% by weight, .

In order to increase the dissolution rate of synthetic silica, the synthetic silica thickener is prepared by first mixing sodium pyrophosphate and defoamer with water at 60 to 85 ° C., mixing at a low speed of 150 to 300 rpm and then mixing with synthetic silica at a rate of 700 to 1,000 rpm To complete dissolution.

The second step of preparing the water-soluble anti-settling agent is to form a water-soluble anti-settling agent comprising 1.5 to 5% by weight of xanthan gum and residual water.

The Xanthan Gum is a mixture of glucose, mannose and glucuronic acid sodium, potassium and calcium salts obtained by purifying the polymer polysaccharide obtained by fermentation into isopropyl alcohol, followed by drying and pulverization, .

In this case, the term "sedimentation prevention" refers to preventing sedimentation during storage of the pigment in the paint to prevent caking at the bottom of the container. When the content is less than 1.5% by weight, the effect of preventing sedimentation is not exhibited. , So it should be limited to the above range.

The water-soluble anti-settling agent is prepared by slowly adding water with a small amount of xanthan gum while slowly stirring water at 50 to 60 ° C at 100 to 300 rpm, and then rotating it at 700 to 1,000 rpm at high speed to completely dissolve xanthan gum.

The third step of preparing the aqueous phase-forming gel comprises mixing 15 to 25% by weight of the synthetic silica thickener, 10 to 25% by weight of the water-soluble particle sedimentation inhibitor, 1-10% by weight of the acrylic emulsion, Of the water gel.

If the addition amount of the synthetic silica thickening agent constituting the water-based gel is less than 15% by weight, the effect of thickening is insufficient. If the added amount is more than 25% by weight, the coating workability may be inferior. If it is less than 10% by weight, caking of the pigment may occur. If it exceeds 25% by weight, physical properties of the coating film may be deteriorated.

In addition, the acrylic emulsion enhances the adhesive function by enhancing the binder function, thereby enhancing the adhesive force after spraying the paint.

For this, in the present invention, it is necessary to add in the range of 1-10% by weight. If it is less than 1% by weight, the adhesive strength tends to be low and adhesion strength can not be expected. .

This aqueous phase gel was completely dissolved by adding the synthetic silica thickening agent while stirring at a low speed of 100 to 300 rpm with water, and then the water-soluble anti-settling agent was added thereto. While stirring, the acrylic emulsion was slowly added at 700-1,000 rpm And completely dissolved.

On the other hand, in the step of producing a water-based multicolor paint containing pearl, a first step of producing a water-soluble paint particle-forming paste, a second step of producing a pigment paste, and a step of blending coloring pearl and a functional material to form a functional blend A third step and a fourth step of making an aqueous color pattern paint using the water-soluble paint particle-forming paste and the pigment paste and the blend.

At this time, the water-soluble paint particle-forming paste prepared through the first step may contain 5 to 10% by weight of the synthetic silica thickener, 1 to 3% by weight of a cellulose-based thickener, 1-5% by weight of a urethane- 2 to 5 weight% of a silane-based water repellent agent, 35 to 55 weight% of an acrylic emulsion or an acryl-styrene emulsion, 10 to 20 weight% of an acrylic emulsion coating film 0.1 to 5% by weight, and the balance water.

Here, the cellulose type thickening agent and the urethane type thickening agent are used together with the synthetic silica thickening agent to keep the viscosity constant so that the watery color pattern paint plays an important role in the formation of color particles of a certain size and maintenance of stability, In addition to complementing features, various thickeners are mixed to reduce cost.

In this case, when the addition amounts of the cellulose-based thickener and the urethane-based thickener are each less than 1% by weight, the viscosity of the water-soluble paint particle-forming paste becomes too low and the pattern may be loosened after the pattern formation or the paint may flow down during coating. % And 5% by weight, the viscosity becomes excessively high, so that the dispersibility of the pattern may be inferior or the workability may be inferior at the time of spray coating.

The calcium carbonate used in the coating composition according to the present invention is used for a water-soluble paint particle-forming paste which is not contained in a pigment paste. If it is used in an amount less than 10% by weight, the constitutional effect may be inferior. By weight, the amount of other main components to be added is limited, so that it is preferable to use within the above range.

If the amount of the acrylic emulsion or the acryl-styrene emulsion is less than 35 wt%, there may be a problem in formation of a coating film. When the acrylic emulsion or the acryl-styrene emulsion is used in an amount exceeding 55 wt% Is preferably used.

In addition, the acrylic emulsion paint film agent is used as a film-forming auxiliary agent which provides plasticity to the water-soluble paint particle-forming paste as a plasticizer. If less than 0.01% by weight is used, , And if it is used in an amount exceeding 5% by weight, the effect of increasing the amount of use is insignificant.

In addition, antiseptics, antifoaming agents, dispersing agents, and silane-based water repellents can be arbitrarily used in the art, and those skilled in the art can appropriately use them in consideration of the contents of the entire coating composition.

The preparation of the water-soluble paint particle-forming paste is carried out by sequentially dispersing and injecting the above components while rotating the water at 700 to 1,000 rpm at a high speed.

Also, the pigment paste prepared by the second step is composed of 1 to 10% by weight of the synthetic silica thickener, 1 to 5% by weight of a dispersant, 0.2 to 2% by weight of an antifoamer, 60 to 72% .

At this time, the pigment may be white titanium dioxide (TiO ₂ ), iron oxide yellow, iron oxide red, iron oxide black, and each pigment paste is prepared according to a predetermined combination of colors to be used.

Here, the iron oxide (ferric oxide: Fe ₂ O ₃ ) pigment is produced using iron sulfate as a raw material in the waste liquid of steel or plating industry. Depending on the particle size, the kind of the inclusion material, and the degree of completeness of the crystal lattice, , Red, black, and the like, all of which are commercially available.

If the amount of the pigment added is less than 60% by weight, the reproducibility of the natural stone particle pattern may not be sufficiently satisfactory, and if it exceeds 72% by weight, caking due to sedimentation may occur.

To prepare such a pigment paste, a synthetic silica thickener, a dispersant, and an antifoaming agent are added to water, and the pigment is slowly added at a low speed of 100 to 300 rpm while agitating at a high speed of 1,000 to 1,600 rpm.

In addition, the functional combination formulated by the third step comprises 5-15% by weight of pearl with a particle size of 1-4 μm, 20-25% by weight of zeolite fine particles with a particle size of 1 μm, 10-15% by weight of borax %, Nonylphenol ethoxylate 2.5-5.5 wt%, conductive carbon black 5-10 wt%, and balance water.

At this time, the pearl is preferably golden pearl or pale yellow pearl, and is added to provide a pearl effect of the coating and provide a high-quality appearance. In addition, zeolite is a microporous hydrated silicate mineral which is excellent in physical adsorption capacity and chemical cation exchange capacity, and is added to realize the environment-friendly property through release of human useful substance.

Further, the borax is a component added to smooth the oil surface of the oxide surface while enhancing the bonding force. And, the nonylphenol ethoxylate is added in order to provide interfacial function while increasing intercalation with the coating, especially to obtain an antioxidant effect. In addition, the conductive carbon black is added in order to enhance sound absorption and adsorption due to small particle size and developed sponge-like structure, and to obtain an antistatic effect.

In addition, the water-based multicolor paint produced by the fourth step is composed of 75 to 85% by weight of the water-soluble paint particle-forming paste, 5 to 10% by weight of the pigment paste and the remaining functional blend.

If the added amount of the water-soluble paint particle-forming paste is less than 75% by weight, the coating film may be insufficiently formed or the physical properties of the formed coating film may be deteriorated. If the amount exceeds 85% by weight, It is also undesirable.

When the addition amount of the pigment paste is less than 5% by weight, there is a fear that a clear natural stone color pattern may not be obtained as mentioned above. When the addition amount is more than 15% by weight, Or the physical properties of the formed coating film may be deteriorated.

The functional blend is added and used depending on the addition amount of the two pastes.

On the other hand, in the step of forming the paint particles, 40 to 50% by weight of water-based colorful paint is mixed with 50 to 60% by weight of the water-based gel, and while stirring and stirring are performed using the impeller 100 shown in FIG. 1, And is dispersed so as to be an aqueous color pattern paint having an average particle size of 1 to 8 mm similar to the above.

If the addition amount of the water-absorbing gel is more than 60% by weight or the amount of the water-based colorful paint is less than 40% by weight, the coloring property is not satisfactory enough, so that natural color or pattern pattern such as natural marble or granite may not be obtained If the addition amount of the water-absorbing gel is less than 50% by weight or the addition amount of the water-based colorful paint exceeds 50% by weight, the physical properties of the coating film, the coating film adhesion and the storage stability of the coating may be inferior, I can not.

Particularly, in the present invention, particles are formed using the impeller 100 shown in FIG. 1 without using a mesh network. In the mesh network, the operation speed is low and the pulverizing and dispersing effect is poor. However, Is fast, and has excellent crushing power and uniform dispersion.

However, in the case of the impeller method, when the size of the particles is reduced by the pulverization, some particles are larger than the other particles, so that they are not crumbled. Thus, the pulverization efficiency is lowered and uniform grinding is difficult. For this reason, mesh networks have been mainly used up to now, despite the above disadvantages.

1, the impeller 100, which is a stirring blade fixed to the rotary shaft R, is twisted by 5-30 ° behind the rotary direction.

This is to lower the rotational direction and increase the opposite side of the rotational direction so that the impeller 100 heats up the paint composition while stirring to increase the dispersing effect. At the same time, the crushing string 110, So that it can be raised.

At this time, the crushing string 110 is wound and fixed to a pair of string fixing pieces 120, which are the same as the piano steel wire and are set up and spaced from each other on the upper surface of the impeller 100.

In this case, the string fixing piece 120 is formed with a plurality of string grooves 130 so that the main string 110 can be wound and fixed.

The string fixing member 120 is fixed near the rotation axis R in parallel with the rotation axis R and is fixed at an angle so that the stirring and pulverizing efficiency can be further increased during rotation do.

This makes it possible to smooth the formation of paint particles, shorten the working time, and enable uniform dispersion.

Thereafter, a glitter mixing step is performed.

In the glitter mixing step, 1-10 parts by weight of glitter is further added and mixed based on 100 parts by weight of the coating composition in which the particles are formed.
Glitter refers to a commonly used decorative glitter and is added in order to have a size of 0.2 to 0.4 mm so as to increase the decorating effect according to glitting without inhibiting stirring and dispersibility.

Hereinafter, a coating method using the water-based multicolor coat paint composition according to the present invention will be described.

The coating method using the water-based multicolor coat paint composition according to the present invention basically includes a lower coating step, a middle-phase coating step, and an upper coating step.

In this case, the undercoating step may be carried out by applying an acrylic emulsion or an acryl-styrene emulsion undercoat to the substrate such as concrete, plywood, wood, chip board, fiber board, gypsum board, acrylic plate, Use a gun to paint.

In this case, the base surface is painted with the most color of the main color in the natural stone to be expressed so as to exhibit excellent hiding power.

Particularly, the undercoating agent for forming the undercoat for enhancing the adherence of the substrate to the base surface and preventing the occurrence of cracks comprises 40 to 50% by weight of an acrylic emulsion or an acryl-styrene emulsion, 0.1 to 2% by weight of a defoaming agent, 5.5 to 7.5% by weight of colloid, 8.5 to 10% by weight of VCI (Volatile Corrosion Inhibitor) powder, 2.5 to 4.5% by weight of zirconia powder coated with octamethylcyclotetrasiloxane and the balance of water.

The acrylic emulsion or the acryl-styrene emulsion is a basic component of the undercoating agent, and the hydrocolloid is added to enhance the adhesion by fixing the stickiness by maintaining the wet state by forming a gel for a long time, It is added not only to be flexible but also to enhance the waterproof function to prevent wetting.

The VCI (Volatile Corrosion Inhibitor) powder is a non-silicon-vaporable corrosion-resistant powder and has an eco-friendly anti-erosion function that does not contain harmful components such as heavy metals and nitrites.

This VCI powder acts to prevent erosion and cracks by preventing vaporized VCI vapors from forming a monolayer on the surface of the molded article and blocking reaction of water and oxygen on the surface of the substrate.

The zirconia powder coated with octamethylcyclotetrasiloxane is intended to improve the dispersion stability and water resistance of the resin composition. Particularly, since octamethylcyclotetrasiloxane is a water-resistant organic material, the zirconia powder has a small specific surface area, Thereby improving the crack resistance and durability while improving the wear resistance by the high hardness characteristics of zirconia.

In addition, the middle-phase coating step is a step of spraying an acrylic-styrene emulsion paint containing calcium carbonate, silica sand, pigment and cellulose thickener on the undercoating agent so as to have texture and volume (embossing) similar to the natural stone surface .

At this time, it is preferable that the color of the medium-phase volume coating is the color of the main color most corresponding to the natural stone to be expressed in order to exhibit excellent hiding power.

Such a thickener is prepared by mixing 0.2 to 4% by weight of a dispersant, 0.1 to 2% by weight of a preservative, 0.1 to 0.5% by weight of a cellulosic thickener, 15 to 20% by weight of an acryl-styrene emulsion, 0.1 to 2% 0.1 to 2% by weight of a colloidal phase clay, 0.1 to 2% by weight of a high boiling point solvent, 0.1 to 3% by weight of a refrigerating stabilizer, 2 to 6% by weight of a white extender pigment (TiO ₂ ) % Of an acrylic thickener, 0.2 to 2% by weight of an acrylic thickener (solid content 33%), and the balance of water, 25 to 35% by weight of silica sand (80 to 150 mesh) have.

The top coating step is a step of coating the water-based multicolor coat composition according to the present invention on the middle-phase with a pressure of 1-5 kg / cm 2 by using a special pressure-fed gun, a tile gun and a patterned coat gun.

In addition, a skin layer coating step may be further performed to prevent the contaminants from adhering to the top surface, to improve the longevity by strengthening mold prevention and moisture resistance, and to form a skin layer having flame retardant properties.

At this time, since the skin layer should not damage various patterns of the upper surface, transparency must be secured.

To this end, in the present invention, the skin coating agent constituting the skin layer comprises 3.5% by weight of melamine cyanurate, 4.5% by weight of pentaerythritol, 10% by weight of a transparent polyethylene resin, 8.5% by weight of PEEK (polyetheretherketone) 1.5% by weight of ammonium bromide, 3.5% by weight of dimethylpolysiloxane, 5.5% by weight of isoquinoline alkaloid, 3.5% by weight of eromol, 3.5% by weight of sodium fucose oxide hydrogel and the rest of the polycarbonate resin.

Thus, the transparency is maintained by the transparent polyethylene resin, the PEEK and the transparent polycarbonate resin.

At this time, the melamine cyanurate has a good dispersibility in the resin and improves the flame retardancy without deteriorating the physical properties of the target resin and has excellent moldability. Particularly, it has an advantage of being able to impart flame retardancy properties without using a large amount because of good compatibility with the polyethylene resin.

In addition, pentaerythritol is a material having intermediate properties between synthetic rubber and plastics, which is added to increase flame resistance and ignition resistance by inducing an increase in the limiting oxygen index during combustion.

The PEEK (polyetheretherketone) is a thermoplastic high-performance plastic resin which is added to maintain transparency, chemical resistance, water resistance and high-temperature stability, and is excellent in lubrication, To improve the antifouling property.

In addition, the above-mentioned trimethylbenzylammonium bromide is added in order to promote curing stability by promoting the reaction and to maintain a strong bonding property of the coating film.

Further, the dimethylpolysiloxane is composed of a siloxane bond (Si-O-Si) strongly resistant to heat and an organic methyl group, and is added to increase foaming resistance, heat resistance, thermal oxidation stability, and chemical resistance.

In addition, the isoquinoline alkaloids are extracts from Bitter Melon, Rhododendron root, and Rootstock root, which are natural bacteriocidal antimicrobial agents that block fungi.

The above-mentioned elemol is added in order to achieve a function of air purifying by releasing a soft fragrance together with a deodorizing effect as well as a natural bacteriostatic function.

In addition, the fusid sodium oxide hydrogel has a hygroscopic property by allowing the hydrophilic polymer to form a hydrogel by expanding the hydrophilic polymer in water containing the fusid sodium oxide powder having high hygroscopicity and thereby obtaining a three-dimensional network structure and a microcrystalline structure.

The blender used for producing the water-based multicolor coat composition of the present invention has the following advantages.

The lower frame 10 includes a lower frame 10 and a lower frame 10. The lower frame 10 includes a lower frame 10 and a lower frame 10, A lifting and lowering portion 20 provided on the upper portion of the rotary frame 30 and provided with a rotary frame 30 on an upper portion thereof for lifting and lowering the rotary frame 30; A high speed mixing unit 50 installed at the rotary frame 30 for rapidly stirring the material in the mixing vessel 1 and a high speed mixing unit 50 installed at the rotary frame 30 for rotating the mixing vessel Speed mixing unit 60 and a low-speed mixing unit 60 that mixes the material in the mixing vessel 1 at a low speed and a low-speed mixer 60 in which the mixing vessel 1 is seated and the mixing vessel 1 is rotated And a mixing container reverse rotation unit 70 for rotating the mixing container in the direction of the arrow.

Therefore, the mixing apparatus of the present invention can be easily moved to a required place, and the low-speed mixing unit 60 and the high-speed mixing unit 50 can be positioned inside the mixing vessel 1 while being horizontally rotated and elevated, Easy to use.

Secondly, the low-speed mixing unit 60 of the present invention is rotated in one direction to float upward while mixing the materials in the mixing vessel 1, while the high-speed mixing unit 50 is rotated in the same direction as the low-speed mixing unit 60 The mixing container reverse rotation unit 70 rotates the mixing container 1 in a direction opposite to the low speed mixing unit 60 and the high speed mixing unit 50 to rotate the mixing container 1 ) Are mixed again by the low-speed mixing unit 60 and the high-speed mixing unit 50. [

Therefore, the materials in the mixing vessel 1 are surely mixed by the low-speed mixing unit 60, the high-speed mixing unit 50, and the mixing vessel counter-rotating unit 70 which is rotated in the reverse direction, .

Thirdly, the mixing vessel counter-rotating part 70 of the present invention is provided with a measuring part 80. The weight of the mixing vessel 1 seated on the mixing vessel counter rotating part 70 is sensed and put into the mixing vessel 1 The amount of material to be measured is measured.

Therefore, when the material is fed into the mixing vessel 1, the amount of the load cell of the measuring unit 80 is directly measured, so that the measurement of the mixed material becomes very simple, thereby greatly improving the workability.

Fourthly, the low-speed wing portion 63 of the present invention includes a coupling boss 64 that is coupled to the lower end of the low-speed shaft 62, and a plurality of radial holes around the coupling boss 64, A wing protection ring 67 which is attached around the wing 65 to support the wing 65 and protects the wing 65 and a wing 65 that protects the wing 65, And a scraper 66 for scraping up the material of the bottom of the mixing vessel 1 upwardly.

Therefore, when the low speed wing portion 63 is rotated, the materials inside the mixing container 1 are mixed while being floated upward by the inclinedly arranged blades 65, and the materials laid on the bottom of the mixing container 1 are scraped The impact is minimized even if the low speed blades 63 are freely moved in the mixing container 1 by the blade protecting ring 67 and hit the inner peripheral surface of the mixing container 1 Thereby preventing the mixing vessel 1 from being damaged.

Fifthly, the high-speed wing portion 56 of the present invention includes a rotary plate 57 coupled to the lower end of the high-speed shaft 55, a rotary plate 57 arranged radially on the upper surface of the rotary plate 57, A high speed blade 58 which is erected at right angles to the high speed blade 56 and stirs the material outside the high speed blade 56 lifted by the low speed blade 63 during the high speed rotation to the inside of the high speed blade 56, And a reinforcing piece 59 connected to the rotary plate 57 and the high-speed blades 58 to reinforce the high-speed blades 58. Since the high-speed blade 56 is curved around the high-speed blade 58, the grains of the material at the time of high-speed rotation are not damaged even if hit by the high-speed blade 58.

Therefore, the granules of the composition are not damaged even when they are mixed by the high-speed blade portion 56 in which the material is rotated at high speed. Since the high speed blade 58 is supported by the reinforcing blade 59, it is prevented that the high speed blade 58 is bent or damaged even if it is rotated at a high speed for a long period of time.

On the other hand, the surface of the high-speed blade 58 may be coated with a corrosion-resistant coating layer to prevent corrosion of the metal surface. The coating material for the anti-corrosion coating layer is composed of 20 wt% of methacototriazole, 15 wt% of petroleum sulfonate, 10 wt% of mercaptobenzothiazole, 15 wt% of hafnium, 10 wt% of molybdenum (MoS2) 30% by weight of aluminum, and a coating thickness of 8 탆.

Methacototriazole, petroleum sulfonate, and mercaptobenzothiazole serve to prevent corrosion and prevent discoloration.

Hafnium acts as a corrosion-resistant transition metal element with excellent waterproofness and corrosion resistance.

Emulsified molybdenum acts to impart wettability and lubricity to the surface of the coating film.

Aluminum oxide is added for the purpose of refractoriness and chemical stability.

The reason why the ratio of the constituent components and the thickness of the coating are limited as described above is that the present inventor has analyzed through several test results, and as a result, showed the optimum corrosion inhibiting effect at the above ratios.

In addition, the outer surface of the high-speed shaft 55 may be coated with an anti-fouling coating layer made of a composition for preventing fouling, so as to effectively prevent and remove the adhesion of the fouling material.

The composition for anti-fouling coating contains alkaline polyglucoside and aminoalkyllaurobetain in a molar ratio of 1: 0.01 to 1: 2, and the total content of the alkylate polyglucoside and aminoalkyllaurobetain is 1 to 10 Weight%.

The molar ratio of the alkylate polyglucoside and the aminoalkyl sucrose is preferably in the range of 1: 0.01 to 1: 2. If the molar ratio is out of the above range, the coating property of the substrate may be lowered or the adsorption of water on the surface may increase, .

The alkaline polyglycoside and the aminoalkylsulbate are preferably used in an amount of 1 to 10% by weight based on the total weight of the composition. When the content is less than 1% by weight, the applicability of the base material is deteriorated. When the content is more than 10% by weight, The crystal precipitation is likely to occur.

On the other hand, as a method of applying the present anti-fouling coating composition onto a substrate, it is preferable to coat it by a spray method. The thickness of the final coated film on the substrate is preferably 500 to 2000 angstroms, more preferably 1000 to 2000 angstroms. If the thickness of the coating film is less than 500 angstroms, there is a problem of deterioration in the case of a high-temperature heat treatment. On the other hand, when the thickness of the coating film is more than 2000 angstroms,

The anti-contamination coating composition may also be prepared by adding 0.1 mol of an alkylate polyglucoside and 0.05 mol of aminoalkylsorbate to 1000 mL of distilled water and stirring.

In addition, a perfume material mixed with a functional oil may be coated on the periphery of the control unit 90, thereby sterilizing the control unit 90 and mitigating the stress of the operator.

The functional oil may be mixed with 95 to 97% by weight of the perfume material and 3 to 5% by weight of the functional oil, and the functional oil may be selected from the group consisting of Acacia dealbata oil 50 By weight, and 50% by weight of Valeriana fauriei oil.

It is preferable that the functional oil is mixed in an amount of 3 to 5% by weight based on the perfume material. If the mixing ratio of the functional oil is less than 3% by weight, the effect is insignificant. If the mixing ratio of the functional oil exceeds 3 to 5% by weight, the function is not greatly improved, but the manufacturing cost is greatly increased.

The main chemical composition of Acacia dealbata oil is palmic aldehyde and enanthic acid. It has a good fragrance and has a good effect on sterilization, anti-aging and stress relief.

Valeriana fauriei oil is the main chemical component of bornyl acetate, pinene, and blood pressure lowering effect, as well as calming and calming the action of the anxiety, relaxation effect is excellent.

Since the functional oil is coated on the control unit 90, not only the control unit 90 can be sterilized, but also helps the operator to recover the fatigue.
