DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is an exploded perspective view of a flameproof sheet according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of a flameproof sheet according to an embodiment of the present invention.

Referring to FIG. 1, a fire-retardant thermal insulation sheet according to an embodiment of the present invention has a structure in which a glass fiber layer 10, a synthetic resin layer 20, and a glass fiber layer 30 on the other side are laminated in order.

The glass fiber layers 10, 30 may comprise a glass fiber fabric containing a fire retardant coating agent. The glass fiber is a well known material having excellent heat insulation and sound absorption effect, and the heat insulating sheet of the present invention is advantageous in that it is possible to use the advantages of the glass fiber while observing disadvantages of the glass fiber such as unpleasant tactile feeling, Thereby improving the practical value of the incombustible heat insulating sheet.

In one embodiment of the present invention, the fire retardant coating agent may include water as melamine cyanurate, aqueous polyurethane, surface treatment agent, and other balance. For example, the fire-retardant coating agent may contain 7 to 13 parts by weight of melamine cyanurate, 9 to 15 parts by weight of an aqueous polyurethane, 2 to 8 parts by weight of a surface treatment agent, and 64 to 82 parts by weight of water.

Polyvinyl alcohol (PVA) may be added as the surface treatment agent to the incombustible coating agent, but the present invention is not limited thereto. The incombustible coating agent may further include at least one of melamine and water-based acrylic to smooth the surface. Further, it may further include at least one of phosphorous pentoxide (P2O5), nitrogen, and urea in order to increase the incombustibility.

The non-burnable coating agent having the above-mentioned composition ratio can be applied to a glass fiber fabric and then heated and dried at a temperature of 80 to 170 ° C.

Various methods can be used for this purpose, such that the glass fiber fabric contains the non-burning coating agent as described above to form the glass fiber layers 10, 30. For example, glass fiber fabrics can be immersed in a non-burning coating agent such as the one described above to impregnate the non-burning coating agent between the fiber yarns of the glass fiber fabric, thereby further increasing the incombustibility of the glass fiber layers 10 and 30.

When the glass fiber cloth 10 and the glass fiber cloth 30 are cut, the nonflammable coating agent is present on the cross-sectional surface of the glass fiber cloth 10 and 30, thereby ensuring the nonflammability of the glass fiber layers 10 and 30 . The time for immersing the glass fiber fabric in the nonflammable coating agent can be determined in consideration of the thickness of the glass fiber fabric, the viscosity of the nonflammable coating agent, the characteristics of the required heat insulating sheet, and the like.

Of course, the method by which the glass fiber fabric contains the fire retardant coating is not limited to the above-mentioned method, and various other methods may be used, for example, by spraying the fire retardant coating agent onto the glass fiber fabric.

In addition, the glass fiber fabric can be immersed in a fire retardant coating and then passed between a pair of rollers. By doing so, it is possible to further impregnate the incombustible coating agent between the fibers of the glass fiber fabric and also to remove the surplus incombustible coating agent liquid on the surfaces of the glass fiber layers 10, 30.

The non-flammable coating agent minimizes the exposure of the glass fiber layer to the surface of the glass fiber fabric, thereby improving the feel of the glass fiber layers 10 and 30, suppressing dust generation, and printing on the surfaces of the glass fiber layers 10 and 30 . By printing various colors or designs on the surface exposed to the outside from the glass fiber layers 10 and 30, the merchantability of the product can be increased.

The synthetic resin layer 20 may be formed of a synthetic resin such as polyethylene (PE) or polyethylene terephthalate (PET). The synthetic resin layer 20 and the glass fiber layers 10 and 30 can be bonded in various ways. For example, the adhesive may be applied to the synthetic resin layer 20 or the glass fiber layers 10 and 30 to attach them to each other. Alternatively, after the synthetic resin layer 20 is deposited on one glass fiber layer 10, The synthetic resin layer 20 may be formed of a curable synthetic resin material to arrange and pressurize the glass fiber layers 10 and 30 in a state before curing and then cure the synthetic resin material to form the synthetic resin layer 20 itself May serve as an adhesive.

In an embodiment of the present invention, the synthetic resin layer 20 itself may serve as an adhesive between the glass fiber layers 10 and 30. That is, a synthetic resin having a predetermined adhesive performance can be used as the material of the synthetic resin layer 20, and various kinds of synthetic resins have a certain degree of adhesion performance before being cured.

Therefore, in one embodiment of the present invention, the synthetic resin layer 20 is formed of a curable synthetic resin material, and the synthetic resin material in a state before curing is disposed between the glass fiber layers 10 and 30, and the glass fiber layers 10 and 30 are pressed The synthetic resin layer 20 itself may act as an adhesive by curing the synthetic resin material.

The method of adhering the glass fiber layers 10 and 30 to the synthetic resin layer 20 before curing may be more effective as the surface roughness of the glass fiber layers 10 and 30 is higher. Therefore, a step of increasing the illuminance of the surface facing the synthetic resin layer 20, particularly on the surface of the glass fiber layers 10 and 30 may be added.

The glass fiber layers 10 and 30 may have greater rigidity than ordinary glass fiber fabrics due to drying or curing of the non-burning coating agent, but the rigidity can be further increased by using the synthetic resin layer 20. That is, when the glass fiber fabric is inferior in rigidity, it may be difficult to process and construct it, which can be prevented by adding the synthetic resin layer 20. For example, the fire-proof and heat-insulating sheet according to an embodiment of the present invention can be applied to insulation of a building by directly attaching to a wall by a stapler, a nail, a piece, It is easy to cut with scissors or the like.

The synthetic resin layer 20 may also increase the smoothness of the synthetic resin layer 20 when the fireproof sheet according to an embodiment of the present invention is used directly as a wallpaper to provide higher overall smoothness, It can serve to cover the surface.

The material used for the synthetic resin layer 20 may be vulnerable to flames, since the glass fiber layers 10, 30 containing the fire-retardant coating are disposed on both sides of the synthetic resin layer 20 to compensate for such weaknesses.

The synthetic resin layer 20 generally has a low permeability, that is, a low water permeability, and a relatively low thermal conductivity. In the case of the outer wall of a building, when the outside temperature is lowered, the surface temperature of the wall is also lowered, and condensation phenomenon may occur in which moisture forms inside the wall. Condensation occurs when the surface temperature of the wall falls below the dew point temperature of the room, so that it occurs more severely when the room is humid. When the fire-retardant insulating sheet according to an embodiment of the present invention is used in such a place, water contained on the surface of the wall is cut off to prevent damages of the glass fiber layer on the room side or the finish material such as wallpaper, . The fireproof insulation layer including the synthetic resin layer 20 can be applied to a portion of the building, such as an outer wall or a ceiling, which is likely to be infiltrated with rain water.

In an embodiment of the present invention, a metal layer (not shown) may be added between the synthetic resin layer 20 and the glass fiber layers 10 and 30. As the metal layer, a material such as aluminum foil can be used. The metal layer can further increase the rigidity of the heat insulating sheet. In addition, by using the metal layer to be attached to the synthetic resin layer 20, the synthetic resin layer 20 can be more reliably cut off from the flame when a fire occurs.

Various methods can be used to add the metal layer to the fireproof sheet according to an embodiment of the present invention. One exemplary method is to use a synthetic resin layer 20 to which a metal layer is added on one surface or both surfaces in advance. As a material to be used for the fire-retardant heat-insulating sheet, a material in which a metal such as aluminum is transferred or vapor-deposited on one side or both sides of a synthetic resin material can be used. A glass fiber layer 10, 30 containing a fire- The heat insulating sheet can be completed. Of course, it will be easily understood that various methods such as attaching a metal foil to one side or both sides of the synthetic resin layer 20 and then attaching the glass fiber layers 10 and 30 may be used in addition to this method.

For this purpose, it may be advantageous to arrange the metal layer closer to the interior space than the synthetic resin layer 20. In this case, the metal layer blocks the synthetic resin layer 20 from the flame, and the synthetic resin layer 20 has a mutually complementary function of blocking the metal layer from water that may condense or permeate through the wall surface. The metal layer may be disposed on one side of the synthetic resin layer 20 or on both sides thereof if necessary.

As another method for increasing the flame retardancy of the synthetic resin layer 20, flame-retardant adhesives 22 and 24 are interposed between the synthetic resin layer 20 and the glass fiber layers 10 and 30 to form a synthetic resin layer 20 and a glass fiber layer 10, 30) can be bonded.

The flame-retardant adhesives 22 and 24 are flame-retardant or flame-retardant adhesives, which can prevent the glass fiber layers 10 and 30 and the synthetic resin layer 20 from burning while maintaining adhesive strength to each other. The flame-retardant adhesives 22 and 24 can be formed by adding a non-flammable or flame-retardant material to a common adhesive component.

As another method for increasing the flame retardancy of the synthetic resin layer 20, the synthetic resin layer 20 itself may contain a flame retardant. For example, in the case of using a hardenable synthetic resin, a synthetic resin may be mixed with a flame retardant and then cured, and the synthetic resin may be used as a material for the synthetic resin layer 20.

Although some methods for increasing the flame retardancy of the synthetic resin layer 20 are illustrated above, it is to be understood that the present invention is not limited to the above-described examples, and various methods other than the above-described methods can be used.

It is especially important to delay the fire in a large space such as a theater or auditorium, and it is also important to design an acoustic system that prevents ringing from occurring due to its characteristics. In order to prevent the sounding of the sound, it is necessary to reflect the sound near the sound source and to absorb the sound near the audience. Since the glass fiber layers 10 and 30 provide excellent sound absorption effect, they can be used in a space where a sound absorption is required in a space such as a theater or auditorium. In this case, the thickness of the glass fiber layers 10 and 30 may be varied depending on the degree of sound absorption required, and a plurality of glass fiber layers 10 and 30 may be used.

As the glass fiber fabric 2 is immersed in the reservoir 5, the glass fiber fabric 2 will contain the incombustible coating agent 4. Although not shown, the glass fiber fabric 2 is allowed to pass through a pair of rollers during or after immersion in the reservoir 5 so that the incombustible coating agent 4 is uniformly absorbed within the glass fiber fabric 2 can do. Of course, the method of causing the glass fiber fabric 2 to contain the fire retardant coating agent 4 is not limited thereto, and various methods can be used as described above.

The glass fiber cloth 2 containing the incombustible coating agent 4 can be heated and dried by the second heating section 6 to form the glass fiber layer 10. [ The second heating portion 6 may also be omitted in some cases, and the non-burning coating agent 4 may be dried by various methods.

For convenience of explanation, FIG. 4 shows an apparatus for producing a fire-retardant insulating sheet on the assumption that the glass fiber layers 10 and 30 have already been manufactured, but it is possible to construct the fire- Those skilled in the art will understand.

When the synthetic resin layer feed roller 41 supplies the synthetic resin layer 20, the first coated portion 40 can apply the flame-retardant adhesive to the synthetic resin layer 20. [ Here, the synthetic resin layer 20 may be a material in which a metal layer is transferred or deposited on one side or both sides. The first application portion 40 may include a reservoir 42, a first application roller 44, and a first pressure roller 46. The first application roller 44 applies the flame-retardant adhesive contained in the reservoir 42 to the synthetic resin layer 20 and the first pressure roller 46 is pressed on the opposite side so that the adhesive is sufficiently applied to the synthetic resin layer 20, .

As described above, the non-flammable coating agent may include water as melamine cyanurate, an aqueous polyurethane, a surface treatment agent, and other balance. For example, the fire-retardant coating agent may contain 7 to 13 parts by weight of melamine cyanurate, 9 to 15 parts by weight of an aqueous polyurethane, 2 to 8 parts by weight of a surface treatment agent, and 64 to 82 parts by weight of water. Polyvinyl alcohol (PVA) may be added as the surface treatment agent to the incombustible coating agent, but the present invention is not limited thereto. The incombustible coating agent may further include at least one of melamine and water-based acrylic to smooth the surface. Further, it may further include at least one of phosphorous pentoxide (P2O5), nitrogen, and urea in order to increase the incombustibility.

The first bonding roller 52 and the second bonding roller 54 in the first bonding portion 50 attach the transferred glass fiber layer 10 to one surface of the synthetic resin layer 20 to which the flame retardant bonding agent is applied.

Likewise, the reservoir 62, the second application roller 64 and the second pressure roller 66 are applied to the other surface of the synthetic resin layer 20, the second application portion 60 is coated with the flame-retardant adhesive, 72 and the fourth joining roller 74 may adhere the glass fiber layer 30 to the corresponding surface.

The glass fiber layers 10 and 30 may be adhered to only one side of the synthetic resin layer 20 as required and other members such as a metal layer may be disposed between the synthetic resin layer 20 and the glass fiber layers 10 and 30 You may.

Of course, the first application portion 40 and the second application portion 60 are integrated and the first joint portion 50 and the second joint portion 70 are integrated to apply the flame-retardant bonding agent to both sides of the synthetic resin layer 20 at the same time And the glass fiber layers 10 and 30 may be attached to both sides of the synthetic resin layer 20 at the same time.

In an embodiment of the present invention, an auxiliary joint portion 80 may be further provided for further pressing the fireproof sheet having the glass fiber layers 10 and 30 and the synthetic resin layer 20 bonded thereto to help the joining. The finished fireproof thermal insulation sheet can be wound around the take-up roller 90 for shipment.

5 is a flowchart of a method of manufacturing a fire-retardant insulating sheet according to an embodiment of the present invention.

First, a flame-retardant adhesive may be applied to one side or both sides of the prepared synthetic resin layer (S510). The synthetic resin layer 20 may be formed of a synthetic resin such as polyethylene (PE) or polyethylene terephthalate (PET). The synthetic resin layer 20 may contain a flame retardant.

Next, the glass fiber layers 10 and 30 are supplied (S520). For this purpose, the process of producing the glass fiber layers 10, 30 by incorporating the fire retardant coating agent 4 in the glass fiber fabric 2 may be preceded. Non-flammable coatings may include water as melamine cyanurate, aqueous polyurethane, surface treatment agent, and other balance. For example, the fire-retardant coating agent may contain 7 to 13 parts by weight of melamine cyanurate, 9 to 15 parts by weight of an aqueous polyurethane, 2 to 8 parts by weight of a surface treatment agent, and 64 to 82 parts by weight of water.

The nonflammable coating agent having the above composition ratio minimizes the exposure of the glass fiber layer on the surface of the glass fiber fabric to improve the feel of the glass fiber layers 10 and 30 and suppress the generation of dust, Thereby enabling printing on the surface of the sheet. By printing various colors or designs on the surface exposed to the outside from the glass fiber layers 10 and 30, the merchantability of the product can be increased.

A glass fiber layer is adhered to one or both surfaces of the synthetic resin layer coated with the flame-retardant adhesive to complete the fire-proof and heat-insulating sheet (S530).

The glass fiber layers 10 and 30 may have greater rigidity than ordinary glass fiber fabrics due to drying or curing of the non-burning coating agent, but the rigidity can be further increased by using the synthetic resin layer 20. That is, when the glass fiber fabric is inferior in rigidity, it may be difficult to process and construct it, which can be prevented by adding the synthetic resin layer 20. For example, the fire-proof and heat-insulating sheet according to an embodiment of the present invention can be applied to insulation of a building by directly attaching to a wall by a stapler, a nail, a piece, It is easy to cut with scissors or the like.

The synthetic resin layer 20 may also increase the smoothness of the synthetic resin layer 20 when the fireproof sheet according to an embodiment of the present invention is used directly as a wallpaper to provide higher overall smoothness, It can serve to cover the surface.

The material used for the synthetic resin layer 20 may be vulnerable to flames, since the glass fiber layers 10, 30 containing the fire-retardant coating are disposed on both sides of the synthetic resin layer 20 to compensate for such weaknesses.

The synthetic resin layer 20 also prevents moisture from being formed on the surface of the wall, thereby preventing damage to the glass fiber layer on the side of the room or the finish material such as wallpaper added thereto due to moisture.
