Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a building frame manufacturing apparatus filled with a heat insulating material,

The present invention relates to a construction frame manufacturing apparatus, and more particularly, to an apparatus for manufacturing a construction frame filled with a heat insulating material by filling a heat insulating material in a hollow portion of a frame without causing a space between the frame and the heat insulating material will be.

A window means a window or a door formed in an opening of a window or an entrance formed in a wall of a building so as to block the inside of the building from the outside, and has a structure in which a shutter plate such as glass is fitted in the window frame.

The window having the opening and closing structure installed in the window includes a window frame frame provided with a plurality of rails in the longitudinal direction and a windowpane provided on the rails.

Meanwhile, the window frames used in these window frames are mainly composed of synthetic resin materials or metal materials. The synthetic resin materials have excellent heat insulation performance and are easy to mass-produce. However, since the material itself has a large elasticity, weak strength, However, there is a disadvantage that toxic gas is emitted in case of fire.

Although the metal window is advantageous in strength, durability and fire resistance, it has a high thermal conductivity, a large heat loss through the frame of the window, and a drawback that condensation occurs in the frame of the window due to the temperature difference between the room and the outside have.

In order to improve the heat insulating property and the soundproofing property of the building frame including the metal window frame, methods for improving the heat insulation and the sound absorbing property by filling a filling material such as foamed material into the empty space inside the building frame have been developed.

The most basic way to fill the filler is to insert a foamed molding such as EPS which has excellent heat insulation according to the size of the empty space of the window frame. It is easy to mold or cut the foamed molding to fit the size of the void space I do not.

If the worker measures the volume of the frame incorrectly or if the foamed molding is too large due to a wrong cut, it is difficult to insert the foamed article into the inside of the frame, or the surface of the foamed article is damaged due to surface friction during the insertion process. In addition, even if the foamed molded article is too small or has a proper size, a gap is formed between the foamed molding and the frame for insertion, so that the heat insulation performance and the soundproofing performance are deteriorated due to the space, and condensation occurs.

As another method of filling the filling material into the frame of the building, foaming may be performed after filling the inside of the frame of the building with a foamable material such as urethane or expandable polystyrene beads. In this case, when the foam material is excessively charged according to the work force of the operator, a convex portion is formed on the frame, so that a lot of expenses are wasted such as peeling off the frame and reworking. There is a problem that cracks or condensation are generated after finishing, and the inside of the frame is rusted due to the occurrence of a gap.

As another method of filling the filler, there is a method of using heat insulating material having fluidity. For example, Korean Patent Laid-Open Publication No. 10-2013-0097029 discloses a method for manufacturing a window frame by forming a foaming insulating material inlet and a bubble outlet in a hollow portion of a window frame and filling the foaming insulating material with an injection member connected to the holes using an injection nozzle And a method of filling the hollow portion of the window frame with the foamed heat insulating material in the form of prefoamed particles which has not been formed through the process of closing the holes. However, in this method, not only the filling process of the pre-expanded particles and the fluid material such as the liquid is troublesome, but when the pre-expanded beads are used, there is a gap in the space between the particles, There are disadvantages.

It has been a cumbersome and difficult task to fill a filling material such as a heat insulator into the inside of a frame having a long and narrow hollow portion like a frame for a window.

FIG. 2 is a schematic view showing the structure of a construction frame manufacturing apparatus filled with a heat insulating material according to an embodiment of the present invention Fig.

4A and 4B, the apparatus for manufacturing a building frame filled with a heat insulating material according to the present invention relates to an apparatus for manufacturing a building frame filled with a heat insulating material inside a frame.

1 and 2, a building frame manufacturing apparatus with a heat insulating material filled therein according to an embodiment of the present invention includes a raw material storage unit 110, a pre-expanded-particle generating unit 120, a pre- A foamed molding forming part 140, a conveying conveyor 150, a heat insulating material forming part 160, a heat insulating material filling part 180 and a frame heating part 190.

The raw material storage unit 110 may be a conventional hopper shape having an inlet and an outlet. Inside the hopper, foamed resin particles as a raw material are stored. For example, the expandable resin particle may be a polystyrene or styrene copolymer resin having a form of a bead having a diameter of 0.2 to 0.3 mm. A first transfer pipe (not shown) for transferring the expandable resin particles to the pre-expanded bead forming part 120 may be connected to the discharge port of the raw material storage part 110.

The pre-expanded-particle generating unit 120 is connected to the raw material storage unit 110 so that the expandable resin particles can be input from the raw material storage unit 110, and the expanded resin particles injected from the raw material storage unit 110 are expanded To produce prefoamed particles having foamability. The pre-expanded particle generating unit 120 may include a reaction vessel equipped with a stirrer, a steam feeder for injecting steam into the reaction vessel, and a second conveyance pipe connected to the pre-expanded bead storage unit 130 from the agitator. (Not shown). In this case, the expandable resin particles transferred from the raw material storage unit 110 are put into the reaction tank and stirred. At this time, steam is injected into the reaction tank through the steam feeder at an internal pressure of 0.2 to 0.4 khf / Foamed to form prefoamed particles.

The pre-expanded bead storage part 130 is connected to the pre-expanded bead generation part 120 so that the pre-expanded bead can be introduced from the pre-expanded bead generation part 120, It is possible to store the prefoamed particles. Although not shown, the pre-expanded-particle storing part 130 may include an aging part made of a silo network having easy ventilation, a drying part for drying aged pre-expanded particles, and a drying part for drying the pre- And a third conveyance pipe connected to the second conveyance pipe. The drying unit may include a chamber and a hot air supplier for supplying hot air into the chamber. In this case, the pre-expanded beads transferred from the pre-expanded bead forming part 120 may be aged for 6 to 12 hours, for example, after being first introduced into the silos of the aging part, and after the aging period, they are put into the chamber of the drying part It can be dried by hot air.

The foamed molding forming unit 140 is connected to the pre-expanded-foamed-particle storing unit 130 so that the pre-expanded-foamed particles can be input from the pre-expanded-foamed particle storing unit 130, The particles can be steam heated to foam to form the foamed molding on the block. For example, the foamed molding forming part 140 may be a mold apparatus.

The mold apparatus includes a cavity mold (fixed mold) and a core mold (core). A molding space is formed between the cavity mold and the core mold. After the pre-expanded beads are injected into the molding space, And then cooled to form an expanded molded article.

When the bead resin is injected into the molding space, the mold apparatus closes the gap between the cavity mold and the core mold slightly (cracking state). This is to increase the density in the mold when the bead resin is injected into the molding space between the cavity mold and the core mold. When the injection of the pre-expanded beads is completed, the cavity mold and the core mold are completely brought into close contact with each other, so that the molding space is completely closed.

For example, the mold apparatus for molding the foamed molded article includes a cavity mold 141 and a core mold 142 as shown in Fig. 2, and the cavity mold 141 is installed on the side of the fixed mold base 143 The core mold 142 is provided on the moving side mold frame 144 side and the moving side mold frame 144 is provided movably with respect to the stationary side mold base 143. [

Although not shown in FIG. 2, the fixed-side mold base includes a fixed-side support plate disposed around the cavity mold, a fixed-side rear plate disposed on the rear surface of the fixed-side support plate, Side frame. A space through which steam or cooling water passes may be formed between the fixed-side rear plate and the fixed-side support plate, and an opening for separately injecting and discharging steam and cooling water may be provided in the fixed-side frame. The feeder and the ejector pin can be installed through the fixed side back plate and the cavity mold, and the feeder can inject the raw material of the pre-expanded particles, and the ejector pin can take out the formed foamed article.

The movable-side mold frame has a movable-side support plate disposed on the periphery of the core mold, a movable-side backplane disposed on the rear surface of the movable-side support plate, a movable-side support plate, and a movable-side frame to which the edges of the movable- A space for passing steam or cooling water is formed between the moving-side rear plate and the moving-side supporting plate, and an opening for separately injecting and discharging steam and cooling water may be provided in the moving-side frame.

At this time, a large number of steam caps perforated with a plurality of steam holes are disposed in the cavity mold and the core mold, and the steam is supplied through the steam cap, so that the pre-expanded particles are heated to perform the foam molding, For cooling, a cooling water pipe may be formed along the inner edge of the stationary side and moving side frame, and a number of branch pipes may be connected to the cooling water pipe to spray the outer surface of each cavity mold and the core mold.

The conveying conveyor 150 can move the foamed material that is installed under the foamed molding forming part 140 and discharged from the foamed molding forming part 140 toward the rear end process, that is, the heat insulating material forming part 160.

The heat insulating material forming unit 160 is disposed at the distal end of the conveying conveyor 150 and cuts the foamed material conveyed through the conveying conveyor 150 into a size that can be inserted into the hollow portion of the frame F having the hollow portion, The heat insulating material 10, 10a to be filled in the hollow portion of the heat insulating member 10 can be molded. Although not shown, for example, the heat insulating material forming portion 160 may include cutting means capable of cutting the foamed molding while moving along the lateral direction and the longitudinal direction of the foamed molded article on the block. In one example, the cutting means may be comprised of a cutting blade or a hot wire. The heat insulating material 10 and 10a formed by cutting the foamed molding through the heat insulating material forming part 160 has 80 to 95% of the volume of the hollow part of the frame F when it is inserted into the hollow part of the frame F. Lt; / RTI > If the volume of the heat insulating material 10, 10a is less than 80% of the volume of the hollow portion of the frame F, it is not preferable because adhesion may be reduced due to insufficient fitting or a gap may be generated. Conversely, The frame (F) may be deformed due to foaming, which is also undesirable.

The water adding portion 170 is disposed between the heat insulating material forming portion 160 and the heat insulating material filling portion 180 and is capable of applying an aqueous adhesive including water to the surfaces of the heat insulating materials 10 and 10a. That is, the water addition part 170 may be disposed at the rear end of the conveying conveyor 150. [ Although not shown, for example, the water addition portion 170 may include an adhesive storage portion for storing an aqueous adhesive containing water, a pump for pumping an aqueous adhesive from the adhesive storage portion, And a spray nozzle for spraying the aqueous adhesive pumped by the pump toward the surface of the heat insulating material (10, 10a) so as to be positioned above the mount and the mount.

Fig. 3 is a view illustrating an injection nozzle constituting the water addition section shown in Figs. 1 and 2. Fig.

Referring to FIG. 3, the injection nozzle 62 allows the aqueous adhesive to spin while forming a vortex when the aqueous adhesive stored in the adhesive reservoir is pumped and injected. The injection nozzle 62 is formed with a threaded coupling part 64 to be coupled with a pipe 67 connected to the pump and a hollow conical body 65 is formed below the coupling part 64, The conical body 65 is formed with a plurality of injection openings 66 through which the aqueous adhesive is finally injected along the spiral direction.

A spiral guide groove 68 is formed on the outer surface of the conical body 65 so as to coincide with the injection opening 66 arranged in the spiral direction. And guides the spraying direction of the adhesive agent in the spiral direction to form a vortex.

The aqueous adhesive agent injected through the helical injection port 66 and the helical guide groove 68 of the vortex type injection nozzle 62 is injected into the heat insulators 10 and 10a while forming a vortex while rotating, 10, and 10a can be evenly coated with an aqueous adhesive.

An eccentric line 69 inclined at about 60 degrees via a bearing is rotatably supported between the coupling portion 64 of the conical body 65 and the pipe 67 to induce rotation of the conical body 65 Respectively.

Accordingly, the aqueous system adhesive injected through the helical injection port 66 and the helical guide groove 68 of the vortex-type injection nozzle 62 rotates and forms a vortex while the eccentric line 69 is connected to the aqueous system adhesive So that the uniform aqueous adhesive is sprayed. As a result, the aqueous adhesive can be easily applied to the heat insulating materials 10 and 10a.

When moisture is added to the heat insulating materials 10 and 10a through the water adding part 170, moisture can be added so that the moisture content of the heat insulating materials 10 and 10a is adjusted to 5 to 10%. If the moisture content is less than 5% by weight, the heat insulating material 10, 10a tends to shrink due to the supplied heat, and there is a high possibility that fitting in the hollow portion of the hollow frame F becomes difficult. Conversely, It is possible to cause a delay in drying of the moisture present in the frame F after the foam foaming, deterioration of the heat insulating property of the heat insulating material 10, 10a due to moisture, and corrosion of the connector used in the assembly process of the frame F So it is also not desirable.

The foaming material is evaporated by heating in a subsequent foaming expansion step, and the foaming material further functions to supply steam to the foaming material. In addition, the foaming material can transmit heat to the foaming material evenly, 10a made of the foamed molded article inserted by the overheating of the heat insulating material 10, 10a is prevented from being contracted or deformed by heat.

Examples of the aqueous adhesive used in the water addition unit 170 include acrylic adhesives such as alkyl acrylate, glycidyl methacrylate and hydroxyalkyl acrylate, EVA adhesives, polyvinyl acetate adhesives, polyvinyl alcohol Based adhesive, a silicate-based inorganic adhesive, and the like, but are not limited thereto. When the aqueous adhesive is used as described above, not only the adhesive can lubricate the insulator 10, 10a into the frame F, but also the surface of the insulator 10, 10a It is possible to prevent a phenomenon that the heat insulating material 10, 10a inserted due to the viscosity of the aqueous adhesive can escape to the outside of the frame F. [

The heat insulating material filling portion 180 is disposed at the rear end of the heat insulating material forming portion 160 and insulates the heat insulating materials 10 and 10a into the hollow portion of the frame F by inserting the heat insulating materials 10 and 10a into the hollow portion of the frame F can do. Although not shown, for example, the heat insulating material charging part 180 includes a mounting part including a region in which a plurality of frames are arranged and a region in which a heat insulating material is arranged such that end portions of the heat insulating material correspond to hollow portions of the respective frames, And a heat insulating material press-in portion which is located at one side of the stationary portion and can press-fit the heat insulating materials corresponding to the hollow portions of the frames into the hollow portion. When the heat insulating material 10, 10a is inserted into the hollow portion of the frame F through the heat insulating material charging portion 180 as described above, the heat insulating materials 10, 10a are made smaller than the hollow portion of the frame F, There is a gap between the heat insulating material 10, 10a and the inner wall of the frame F, and water added such as the aqueous adhesive 12 is present in this gap.

The frame heating unit 190 heats the frame F which is disposed at the rear end of the heat insulating material charging unit 180 and into which the heat insulating materials 10 and 10a are inserted to heat the heat insulating materials 10 and 10a in the frame F It can be further foamed and expanded. Although not shown, for example, the frame heating unit 190 may include a heat chamber provided with a heating means and a stacking means capable of stacking and moving the frames. In this case, it is possible to load the frames onto the stacking means and move them to the heat room, and further heat-insulate the heat insulators in the heat room. For example, steam or dry hot air can be used for heating the heat chamber, and the additional foaming process can be performed for 5 to 15 minutes by setting the heat treatment temperature of the frame at 100 to 160 ° C.

In this case, when the temperature of the heat chamber is less than 100 ° C., it takes too much time for additional foaming of the heat insulating material, which is not preferable because the added water may be evaporated early before the additional foaming of the heat insulating material is completed, The additional foaming of the heat insulating material is excessively quick and excessive, which may cause deformation of the frame, which is also undesirable.

In the process of further foaming the heat insulating material, the heat insulating material 10, 10a expands inside the frame F to fill the gap with the inner wall of the frame F and come into close contact with the inner wall of the frame F. At this time, while the moisture is evaporated by the further foaming, the adhesive 12 coated on the surface of the heat insulating material is solidified to form an adhesive layer, so that the heat insulating material 10, 10a further foamed is fixed to the inner wall of the frame F .

When the additional foamed heat insulating materials 10 and 10a are tightly fixed to the inner wall of the frame F, the airtightness between the heat insulating materials 10 and 10a and the frame F is lowered, And the like can be prevented from occurring, and the effect of high heat insulation and sound insulation can be secured.

Hereinafter, a process for manufacturing a building frame filled with a heat insulating material through a building frame manufacturing apparatus filled with a heat insulating material according to an embodiment of the present invention will be briefly described.

First, the foamable resin particles stored in the raw material storage unit 110 are transferred to the pre-expanded-particle generating unit 120, and the pre-expanded-particle generating unit 120 foam the expanded resin particles to produce pre-expanded particles having foamability .

The pre-expanded beads produced in the pre-expanded bead formation part 120 are transferred to the pre-expanded bead storage part 130 and stored in the pre-expanded bead storage part 130, The pre-expanded particles are aged and dried.

After the aging and drying of the pre-expanded beads are completed, the pre-expanded beads are transferred from the pre-expanded bead storage part 130 to the foamed molded part forming part 140 and introduced therein. In the molding device constituting the foamed molded part forming part 140 The prefoamed particles are steam heated to foam to mold the foamed molding on the block. The foamed molded product on the block on which molding has been completed is discharged from the inside of the mold apparatus toward the conveying conveyor 150.

The conveying conveyor 150 conveys the foamed material discharged from the foamed molding forming part 140 to the insulating material forming part 160.

The heat insulating material forming unit 160 cuts the foamed molded product conveyed through the conveying conveyor 150 to a size that can be inserted into the hollow portion of the frame F so that the heat insulating material 10, ).

The heat insulating material 10, 10a molded in the heat insulating material forming part 160 is transferred to the water adding part 170. [ At this time, the heat insulating materials may be placed on the holder of the water adding part 170 illustrated above, and the spray nozzles may be provided with water by applying an aqueous adhesive containing water to the surfaces of the heat insulating materials.

The heat insulating material 10, 10a to which the moisture is added is conveyed to the heat insulating material charging unit 180. Insulating materials to which moisture has been added in the heat insulating material charging unit 180 are inserted and filled into the hollow portions of the respective frames.

Next, the frames filled with the heat insulating material are transferred to the frame heating unit 190. At this time, a plurality of frames filled with the heat insulating materials 10 and 10a are loaded on the loading means of the heat insulating material charging unit 180, , And heat-treated in the heat chamber to further foam the insulation.

In the construction frame manufacturing apparatus filled with the heat insulating material according to an embodiment of the present invention, a heat insulating material having a size that can be inserted into the hollow portion of the frame is formed, and the molded heat insulating material is molded in the form of a foamed It is possible to fabricate a building frame which can be firmly attached to the inner wall of the frame F as it is expanded and expanded in conformity with the hollow portion of the frame F to secure high heat insulation and sound absorption.

The formed heat insulating materials 10 and 10a are inserted into the hollow portion of the frame F after moisture is added by the aqueous system adhesive 12 containing water and are further foamed so that the heat insulating materials 10 and 10a and the frame F The adhesive layer formed by the solidification of the aqueous adhesive 12 is formed, so that the adhesion of the filled heat insulating materials 10 and 10a is enhanced.

The construction frame made by filling the heat insulating material as described above can be used for various purposes. Typically, a heat insulating material is filled in a metal material profile formed by extrusion molding of aluminum or the like and having a hollow portion therein, have.

Hereinafter, a construction frame manufacturing apparatus filled with a heat insulating material according to another embodiment of the present invention will be described with reference to FIG. 6, focusing on differences from a construction frame manufacturing apparatus filled with a heat insulating material according to an embodiment of the present invention. FIG. 6 is a view for explaining a foamed molded product selecting part of a building frame manufacturing apparatus filled with a heat insulating material according to another embodiment of the present invention.

The apparatus for manufacturing a building frame filled with a heat insulating material according to another embodiment of the present invention may further include a foamed molded product selecting unit 200 shown in FIG. 6, The foamed molded product selecting unit 200 will be mainly described below.

The foamed-molded-material sorting unit 200 picks up the internal structure of the foamed molding conveyed through the conveying conveyor 150 and selects whether or not the foamed molding is defective. The foam molding selection unit 200 may include a radiation source 210, a scintillator 220, a light receiving unit 230, and a display unit 240.

The radiation source 210 is disposed at one side of the conveying conveyor 150 and is disposed perpendicular to the direction of rotation of the conveying conveyor 150 and projects the radiation beam toward the foam molding 1 conveyed through the conveying conveyor 150 do.

The display unit 240 receives the image information from the light receiving unit 230 and displays the image information as an image that can be confirmed.

The image finally displayed on the display unit 240 through this process is an image representing the internal structure of the foamed molding 1 and the internal structure of the foamed molding 1 is confirmed through the image displayed on the display unit 240 The resin beads constituting the foamed molding 1 are uniformly tightly bonded to each other to confirm whether or not the foamed molded article 1 has been molded.

If the internal structure of the foamed molding 1 is not uniform, for example, if the internal structure of the foamed molding 1 confirms the photographed image, it is judged that the foamed molding 1 is defective when a large number of empty spaces are present, The foamed molded article 1 can be removed from the transfer line before reaching the insulation molding portion 160 shown in Figs.

If a construction frame manufacturing apparatus filled with a heat insulating material according to another embodiment of the present invention is used, it is judged whether or not the foamed molding 1 constituting the heat insulating material is defective in the manufacturing process of the building frame filled with the heat insulating material, It may be possible to manufacture a building frame filled with a heat insulating material without any insulation.

The cavity mold 141 and the core mold 142 of the building frame manufacturing apparatus filled with the heat insulating material according to the embodiments of the present invention may be made of a material such as a galvanized steel sheet or an aluminum material. And the surface of the core metal mold 142 may be formed of a surface coating material of a metal material in order to prevent corrosion of the surface from dust, contaminants and the like. The coating layer is composed of 60 wt% of alumina powder, 30 wt% of NH ₄ Cl, 2.5 wt% of zinc, 2.5 wt% of copper, 2.5 wt% of magnesium and 2.5 wt% of titanium.

The alumina powder is added for the purpose of sintering, entangling, fusion prevention, etc. when heated to a high temperature. When such an alumina powder is added in an amount of less than 60% by weight, the effect of sintering, entangling and fusion prevention is deteriorated. When the alumina powder exceeds 60% by weight, the above effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable to add 60 wt% of the alumina powder.

The NH ₄ Cl reacts with steam, aluminum, zinc, copper, and magnesium to activate diffusion and penetration. This NH ₄ Cl is added in an amount of 30% by weight. When NH ₄ Cl is added in an amount of less than 30% by weight, the reaction with aluminum, zinc, copper and magnesium in a vapor state is not properly performed, thereby failing to activate diffusion and penetration. On the other hand, if NH ₄ Cl exceeds 30 wt%, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable to add 30 wt% of NH ₄ Cl.

The zinc is compounded to prevent corrosion of the metal that is in contact with water and to be used for electrical applications. 2.5% by weight of this zinc is mixed. If the mixing ratio of zinc exceeds 2.5% by weight, corrosion of the metal which is in contact with water can not be properly prevented. On the other hand, when the mixing ratio of zinc exceeds 2.5% by weight, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable that zinc is mixed at 2.5% by weight.

The copper is combined with the aluminum to increase the hardness and tensile strength of the metal. This copper is mixed at 2.5% by weight. If the mixing ratio of copper is less than 2.5 wt%, the hardness and tensile strength of the metal can not be properly increased when combined with aluminum. On the other hand, when the mixing ratio of copper exceeds 2.5% by weight, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, copper is preferably mixed at 2.5% by weight.

Since the pure metal of magnesium has a low structural strength, it is used in combination with the zinc and the like to improve the hardness, tensile strength and corrosion resistance of the metal. This magnesium is mixed at 2.5% by weight. When the mixing ratio of magnesium is less than 2.5% by weight, the hardness, the tensile strength and the corrosion resistance to the salt water of the metal are not greatly improved when they are combined with zinc and the like. On the other hand, when the mixing ratio of magnesium exceeds 2.5% by weight, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable that magnesium is mixed with 2.5% by weight.

The titanium is a lightweight, hard and corrosion resistant transition metal element with a silver-white metallic luster. Because it has excellent corrosion resistance and specific gravity, it weighs only 60% of steel. Therefore, the weight of the coating material applied to the metal base material is reduced, Excellent water resistance and corrosion resistance.

This titanium is mixed at 2.5% by weight. If the mixing ratio of titanium is less than 2.5% by weight, the weight of the coating material applied to the metal base material is not so reduced, and glossiness, water resistance and corrosion resistance are not greatly improved. On the other hand, when the mixing ratio of titanium exceeds 2.5% by weight, the above effect is not further improved, but the material cost is greatly increased. Therefore, titanium is preferably mixed at 2.5% by weight.

The application method of the application layer is as follows.

The base material in which the coating layer is to be formed and the coating material blended in the above composition are put in the closed furnace together with the argon gas being injected at a rate of 2 L / min in order to prevent oxidation of the base material inside the furnace. And maintained at a temperature of 700 ° C to 800 ° C for 4 to 5 hours.

Aluminum powder, alumina powder, zinc, copper, magnesium, and titanium compounds penetrate into the surface of the base material to form a coated layer, .

After the coating layer is formed, the inside temperature of the closed material is maintained at a temperature of 800 ° C. to 900 ° C. for 30 to 40 hours so that a coating layer for corrosion prevention is formed on the surface of the base material to isolate the surface of the base material from the outside air do. At this time, the abrupt temperature change in the above-mentioned process may cause the coating layer on the surface of the base material to peel off, so that the temperature is changed at a rate of 60 ° C / hr.

The coating layer of the present invention has the following advantages.

Since the application layer of the present invention has a very wide range of applications, it can be applied by various methods such as curtain coating, spray painting, dip coating, flooding and the like.

In addition to the principle protection against corrosion and / or scale, the application layer of the present invention can be applied with a very thin layer thickness in addition to improving electrical conductivity, as well as material and cost saving. A thin electrically conductive primer may be applied to the top of the application layer if high electrical conductivity is desired after the hot forming process.

After the molding process or the hot forming process, the coating material can be retained on the surface of the substrate, for example, to increase scratch resistance, to improve corrosion protection, to meet aesthetic appearance, to prevent discoloration, And may be provided as a primer for conventional downstream processes (e.g., impregnated and electro-mobile dip application).

Therefore, in the present invention, the cavity mold 141 and the core mold 142 are made of a material such as a galvanized steel sheet or an aluminum material, and the surface of the cavity mold 141 and the core mold 142 made of such materials are coated with alumina powder , NH ₄ Cl, zinc, copper, magnesium, and titanium are coated on the surfaces of the cavity mold 141 and the core mold 142 from dust, pollutants, and the like.

On the other hand, the inner surface of the hopper constituting the raw material storage part 110 of the construction frame device filled with the heat insulating material of the embodiments of the present invention is coated with a composition for anti-fouling coating A coating layer may be formed. The antifouling coating composition contains boric acid and sodium carbonate in a molar ratio of 1: 0.01 to 1: 2, and the total content of boric acid and sodium carbonate is 1 to 10 wt% with respect to the total aqueous solution. In addition, sodium carbonate or calcium carbonate may be used as a material for improving the coating property of the coating layer, but sodium carbonate is preferably used. The molar ratio of boric acid to sodium carbonate is preferably 1: 0.01 to 1: 2. If the molar ratio is out of the above range, the coating property of the base material is lowered or the moisture adsorption on the surface is increased.

The boric acid and sodium carbonate are preferably used in an amount of 1 to 10% by weight in the aqueous solution of the composition. If less than 1% by weight, the coating property of the base material is deteriorated. If the amount is more than 10% by weight, It is easy to occur.

As a method of applying the composition for anti-fouling coating on a substrate, it is preferable to apply the coating composition by a spray method. The thickness of the final coated film on the substrate is preferably 500 to 2000 angstroms, and more preferably 1000 to 2000 angstroms. When the thickness of the coating film is less than 500 ANGSTROM, there is a problem that it deteriorates in the case of a high-temperature heat treatment. When the thickness is more than 2000 ANGSTROM, crystallization of a coated surface tends to occur.

In addition, the composition for antifouling coating can be prepared by adding 0.1 mol of boric acid and 0.05 mol of sodium carbonate to 1000 mL of distilled water and then stirring.
