Description

Manufacturing method of exterior panels for construction {MANUFACTURING METHOD OF EXTERIOR PANEL FOR ARCHITECTURES}

The present invention relates to a method for manufacturing an exterior panel for building in which a core is bonded between a pair of plates, and more particularly, a gas generated in the process of bonding the core with an adhesive is easily discharged to the outside so that the surface of the plate is flat. It relates to a method of manufacturing an exterior panel for building that can be maintained in a manner that can be maintained.

In general, the exterior wall of a building is equipped with a finishing material to enhance the design of the building. Bricks or tiles may be used as such a finishing material, and currently, an exterior panel commonly referred to as a composite panel is widely used.

The exterior panel is basically composed of a metal plate on the outside, and a core having a flame retardant or heat insulation function is filled inside the exterior panel. In the case of currently used exterior panels, a honeycomb-shaped core made of aluminum is mainly used.

At this time, the core is bonded to the plate by a flame-retardant adhesive, and since a large amount of gas is generated during the curing process of the flame-retardant adhesive, the plate is bent or deformed by the pressure of the gas generated from the flame-retardant adhesive. In particular, when the core has a honeycomb shape, since a plurality of air chambers are formed inside the core, a phenomenon in which the plate material of the corresponding part is convexly deformed outward occurs frequently when gas is generated.

In this way, if the plate material is deformed without maintaining the shape of the plate, the appearance becomes very poor, and thus the value as an exterior panel is significantly deteriorated.

1 is a flow chart of a method for manufacturing an exterior panel for a building according to the present invention.

The method for manufacturing an exterior panel for building according to the present invention is a manufacturing method for manufacturing an exterior panel for building in which a core is bonded between a pair of sheet materials, that is, an exterior sheet and an interior sheet, and a large amount of gas in the process of bonding the core with an adhesive. The greatest feature is that the outer plate is configured to not be deformed by the pressure of the gas by smoothly discharging the generated gas even if the gas is generated.

That is, the method for manufacturing an exterior panel for building according to the present invention includes a first step (S10) of seating the outer plate on a work table so that the inner side of the outer plate faces upward, and an adhesive is applied to the inner side of the outer plate. A second step (S20), a third step (S30) of seating the core on the inner side of the outer plate, and a fourth step of seating a perforated plate having a plurality of perforated holes vertically formed on the upper portion of the core ( S40), a fifth step of mounting a plurality of spacers on the upper surface of the perforated plate (S50), a sixth step of pressing the plurality of spacers downward using a press (S60), and when curing of the adhesive is completed A seventh step (S70) of removing the spacer and the perforated plate, applying an adhesive to the inner side of the inner plate, seating the inner side so that the inner side of the inner plate is in contact with the upper end of the core, and pressing the inner plate downward. The biggest feature is that it is configured to include the eighth step (S80), and the gas generated from the adhesive can be smoothly discharged to the outside of the exterior panel.

Hereinafter, each step will be described in detail with reference to the accompanying drawings.

2 and 3 are cross-sectional views illustrating a process of seating a core on an outer plate, and FIG. 4 is a perspective view of the core.

In the case of manufacturing an exterior panel by the method for manufacturing an exterior panel for building according to the present invention, first, as shown in FIG. 2, the outer plate 100 is placed on a work table so that the inner side of the outer plate 100 faces upward. 10) After seating on the surface, the adhesive 200 is applied to the inner surface of the outer plate 100.

At this time, the worktable 10 is formed such that the upper surface forms a perfect plane so that the entire outer surface of the outer plate 100 can be in contact.

In addition, the adhesive 200 is an adhesive for a non-combustible panel, and the main substrate is a polyisocyanate prepolymer. In general, when manufacturing the non-flammable adhesive 200, organic and inorganic flame retardants are added.When a large amount of organic flame retardants are added, the amount of smoke is increased, and if a large amount of inorganic flame retardants is added, the flame retardant effect is good, but elasticity There is a disadvantage in that the modulus value is increased a lot and the adhesive strength is lowered.

Accordingly, the adhesive 200 is manufactured to increase the thermal stability of the substrate itself by making isocyanurate by trimeric reaction of the polyisocyanate prepolymer, which is the main substrate, using a phase transfer catalyst.

As the isocyanate, 2,2-methyldiphenyl isocyanate, 2,4-methyldiphenyl isocyanate, 4,4-methyldiphenyl isocyanate, polymethyldiphenyl isocyanate, 2,4-toluene diisocyanate, 2, 6-toluene diisocyanate, isopropyl diisocyanate, hexamethylene diisocyanate, and the like can be used. In addition, as a phase transfer catalyst, tetramethylammonium formate, tetramethylammonium acetate, tetramethylammonium propionate, tetramethylammonium octoate, tetramethylammonium phosphonate, tetramethylammonium prolide, tetramethylammony Umchromide, tetramethylammonium bromide, tetramethylammonium iodide, etc. can be used. (0.01~1.0 pphp.)

By using the selected isocyanate and catalyst, isocyanurate having high heat resistance can be prepared as shown in [Chemical Formula 1] below.

[Formula 1]

The synthesized high heat resistance isocyanurate may be prepared as a prepolymer that can be used as a one-component adhesive 200 using the following polyol. Polyols are polypropylene glycols with a functional group of 2 and a molecular weight of 200, 400, 600, 750, 1000, 2000, 3000, 4000, and a functional group of 3 and a molecular weight of 400, 600, 700,1000, 2000, 3000, Polyols of 4000, 5000 can be used. In addition, ethylene glycol, propylene glycol, diethylene glycol, dipropylene glycol, glycerin, 1,4-butylene glycol, trimethylpropanol, and the like may be used as the crosslinking agent.

On the other hand, the adhesive 200 used in the method for manufacturing an exterior panel for building according to the present invention is not limited to the adhesive 200 made of the above-mentioned components, and can be applied as various types of adhesives 200. However, since the adhesive for non-combustible panels has a characteristic that a large amount of gas is generated during the curing process, when the adhesive 200 included in the present invention is applied as an adhesive for non-combustible panels, the effect of preventing the deformation of the outer panel 100 is further improved. It has the advantage of being bigger.

When the application of the adhesive 200 is completed, the core 300 is seated on the inner surface (the upper surface in this embodiment) of the outer plate 100 (S30), and the core 300 is applied to the external force applied from each direction. It is manufactured in a honeycomb structure so that it can have uniform structural rigidity. The core 300 manufactured in the honeycomb structure as described above is also commercialized in a conventional exterior panel, and a detailed description of the shape of the core 300 will be omitted.

5 is a cross-sectional view illustrating a process of mounting the perforated plate 400 and the spacer 500 on the core 300, and FIGS. 6 and 7 are perspective views of the perforated plate 400 and the spacer 500, and FIG. 8 and 9 is a cross-sectional view illustrating a process of compressing the core 300 to the outer plate 100.

When the core 300 is seated on the outer plate 100, the core 300 must be pressed toward the outer plate 100 (downward in this embodiment) to press the core 300 to the outer plate 100. . At this time, when the upper end of the core 300 is directly pressed with the press 20, the lower opening of the inner space of the core 300 is blocked by the exterior panel, and the upper opening of the inner space of the core 300 is closed to the press 20. As a result, the gas generated by the adhesive 200 and filled in the inner space of the core 300 is not discharged to the outside and is trapped in the inner space of the core 300.

When the amount of gas generated from the adhesive 200 increases, the pressure in the inner space of the core 300 increases and the outer plate 100 is deformed, thereby deteriorating the appearance of the outer panel, thereby reducing the value. Will occur.

The method of manufacturing an exterior panel for building according to the present invention does not directly press the core 300 with a press 20 to solve the above problems, but a perforated plate 400 and a spacer on the upper part of the core 300. The biggest feature is that the core 300 is pressed against the outer plate 100 by pressing the spacer 500 downward after sequentially seating 500). That is, when the core 300 is seated on the outer plate 100, as shown in FIG. 5, the perforated plate 400 is seated on the top of the core 300 (S40), and on the upper surface of the perforated plate 400 A plurality of spacers 500 are mounted (S50). When seating of the perforated plate 400 and the spacer 500 is completed, as shown in FIG. 8, by pressing the plurality of spacers 500 downward using a press 20 as shown in FIG. 9, the core 300 ) Is pressed to the outer plate 100.

At this time, a space is secured between the press 20 and the perforated plate 400 by the thickness of the spacer 500, and a plurality of perforated holes 410 open in the vertical direction are formed in the perforated plate 400, Gas generated from the adhesive 200 and filled in the inner space of the core 300 may be discharged to the outside through the perforated hole 410.

In this way, when the exterior panel manufacturing method according to the present invention is used, the gas generated from the adhesive 200 is not accumulated in the inner space of the core 300 but is discharged to the outside through the perforated hole 410, so that the outer plate ( There is an advantage that 100) is not deformed by the pressure of the gas.

In addition, the core 300 has a honeycomb structure so that the gas filled in the inner space of the core 300 can be discharged not only through the upper end of the core 300 but also through the sidewall. A discharge hole can be formed. When a plurality of gas discharge holes are formed in the sidewall of the core 300 as described above, the gas generated from the adhesive 200 is not discharged only into the space between the perforated plate 400 and the press 20, but the sidewall of the core 300 There is an advantage that it can be discharged directly to the outside after passing through.

On the other hand, when the spacer 500 for securing a spaced space between the perforated plate 400 and the press 20 is formed in a block shape, a point corresponding to the spacer 500 among a plurality of internal spaces formed in the core 300 The internal space of the spacer is blocked by the spacer 500 and is isolated from the outside, so that gas may not be discharged smoothly. Therefore, the spacer 500 has a rectangular tube shape with an empty inside, but it is preferable that a plurality of through holes 510 are formed in all side walls.

When a plurality of through holes 510 are formed in the spacer 500 as described above, the gas filled in the inner space of the core 300 is the perforated hole 410 of the perforated plate 400 and the through hole 510 of the spacer 500 Since it can be discharged to the outside by passing through sequentially, there is an advantage that the discharge efficiency of the gas is remarkably increased.

In addition, while the press 20 presses the spacer 500 downward, a separate air is blown between the press 20 and the work table 10 so that the gas generated from the adhesive 200 is forcibly discharged. Sungpung fan of can be installed. When the blowing fan 30 is installed in this way, a large amount of wind between the press 20 and the work table 10 while pressing the core 300 to the outer plate 100 with the press 20 as shown in FIG. 9 When this is passed, the gas generated from the adhesive 200 can be more effectively discharged.

Meanwhile, the spacer 500 is preferably formed in a hollow tube shape with an empty inside so that the spacer 500 does not inhibit the flow of wind. At this time, if the spacer 500 is formed in a cylindrical shape, the spacer 500 may move while the press 20 presses the spacer 500 downward, so the spacer 500 is as shown in this embodiment. It is preferably formed in a square tube shape.

In addition, the outer plate material 100 used for the exterior panel is generally formed with a side plate 110 at the edge, and if the wind provided from the blowing fan 30 is blocked by the side plate 110 and cannot be transmitted to the core 300 The efficiency of gas discharge decreases. Accordingly, a plurality of vent holes 112 may be formed in all side plates 110 of the spacer 500 as shown in the enlarged view of FIG. 9.

When the curing of the adhesive 200 for bonding the core 300 to the outer plate 100 is completed, the spacer and the perforated plate 400 are removed (S70), and the inner plate 600 as shown in FIG. An adhesive 200 is applied to the side to place the inner plate 600 on the top of the core 300. At this time, the adhesive 200 applied to the inner side of the inner plate 600 serves to bond the upper end of the core 300 and the inner side of the inner plate 600. On the other hand, the inner plate 600 is pressed downward so that the inner plate 600 can be firmly coupled to the upper end of the core 300 (S80), at this time, downward pressure of the inner plate 600 is shown in FIG. It can be made by the press (20).

When the coupling of the inner plate 600 is completed as shown in FIG. 11, the outer glass 700 is bonded to the outer surface (lower side in FIG. 12) of the outer plate 100 as shown in FIG. (S90). When the exterior glass 700 is bonded to the outer surface of the outer plate 100 as described above, not only the outer surface of the exterior panel becomes beautiful, but also the effect of improving the strength of the outer plate 100 can be obtained.

At this time, the method of bonding the exterior glass 700 to the outer panel of a metal material is widely commercialized in the technical field corresponding to the present invention, and a detailed description of the method of bonding the exterior glass 700 to the outer panel is omitted. do.
