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 heat insulating sheet according to an embodiment of the present invention has a structure in which a glass fiber layer 10, a burnishing paper 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 burnishing paper 20 is a paper having a flame retardant property and is made of paper such as aluminum hydroxide (Al (OH) 3; ATH), magnesium hydroxide (Mg (OH) 2; MDH), hydromagnesite, huntite ), Borax and other mineral flame retardants; Organohalogen compounds such as chlorendic acid, decabromodiphenyl ether (DBDPO), tetrabromobisphenol A (TBBPA), and hexabromocyclododecane; And organic phosphorus compounds such as triphenyl phosphate (TPP), bisphenol A diphenyl phosphate (BADP), and tricresyl phosphate (TCP) Lt; / RTI >

The burned paper 20 and the glass fiber layers 10 and 30 are bonded to each other. For example, after the flame retardant adhesive is applied to both sides of the burnishing paper 20, the glass fiber layers 10 and 30 corresponding to the face can be attached. In some embodiments of the present invention, the burned paper 20 may be constructed by treating the paper fiber layer with a flame-retardant adhesive. That is, both the flame retardant and the adhesive may be added during the production of the coarse paper 20 to facilitate the bonding between the coarse paper 20 and the glass fiber layers 10 and 30.

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 stiffness can be further increased by using the coarse paper 20. That is, when the glass fiber fabric is loosened due to the lack of rigidity, it may be difficult to process and construct the glass fiber fabric.

That is, the flameproof sheet according to an embodiment of the present invention composed of the burnished paper sheet 20 and the glass fiber layers 10 and 30 maintains excellent stiffness, Can be improved.

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 coarse fleece 20 can also increase the smoothness of the coarse thermal insulation sheet according to one embodiment of the present invention, when used directly as wallpaper, the coarse fleece 20 provides a higher overall smoothing, It can serve to cover the surface.

It may be difficult to increase the thickness of the glass fiber layers 10 and 30 but it is possible to increase the total thickness of the glass fiber layers 10 and 30 by bonding the glass fiber layers 10 and 30 via the coarse paper 20 Do.

The glass fiber fabric constituting the glass fiber layers 10 and 30 provides advantages such as high sound absorption performance, low weight, high internal combustion performance and high heat insulation performance. When adding other members between the glass fiber layers 10 and 30, Advantages can be degraded. However, since the burnished paper 20 is lightweight, has good sound absorption performance and heat insulation performance, and has a flame retardant performance, even when the burned paper 20 is interposed between the glass fiber layers 10 and 30, , The internal combustion performance and the heat insulation performance can be maintained, and the increase in weight can be minimized.

It is of course possible to further provide an additional flame retardant on the outer surface of the glass fiber layers 10 and 30 and to further add additional glass fiber layers on the outer surface thereof. That is, the number of the glass fiber layers 10, 30 and the bunched paper 20 can be changed as needed.

The flame retardant performance is further enhanced as the glass fiber layers 10 and 30 containing the incombustible coating agent are disposed on both sides of the coarse paper 20 although the coarse paper 20 itself is flame retarded.

Conventional materials that generally have a high water permeability, that is, a high water permeability and a relatively low thermal conductivity, can be used for the burnishing paper 20. 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 non-burning insulation layer including the burnishing paper 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 one embodiment of the present invention, at least one of the glass fiber layers 10 and 30 may further include a reinforcing layer (not shown) on the outer surface thereof. As the reinforcing layer, a metal layer such as aluminum foil may be used. The metal layer can further increase the rigidity of the heat insulating sheet and can increase the heat insulating performance of the heat insulating sheet to radiant heat to some extent.

In one embodiment of the present invention, a reinforcing layer may be disposed inside to adjoin the wall surface. In this case, the glass fiber layers 10 and 30 can protect the reinforcing layer from the flame while the reinforcing layer can block the flame retardant from water that may condense or penetrate into the wall surface.

When the reinforcing layer is provided on the outer surface of the glass fiber layers 10 and 30 on the outside of the heat insulating sheet, that is, when the reinforcing layer is disposed near the indoor space, the reinforcing layer can be formed of the same material as the fire resistant paper 20. In this case, it will be possible to easily print various colors and designs on the coarse paper 20.

Between the coarse paper 20 and the glass fiber layers 10 and 30 are provided flame retardant adhesives 22 and 24 interposed between the coarse paper 20 and the glass fiber layer 10 , 30) can be adhered. As described above, in some embodiments, the burned paper 20 itself may be considered to include flame-retardant adhesives 22, 24.

The flame-retardant adhesives 22 and 24 are non-flammable or flame-retardant adhesives that can prevent burning of the glass fiber layers 10 and 30 and the burnished paper 20 while maintaining adhesion 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.

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. The thickness of the glass fiber layers 10 and 30 may be varied depending on the required degree of sound absorption and the glass fiber layers 10 and 30 and the bunch paper 20 may be used in multiple layers as described above.

The glass fiber fabric 2 can be immersed in a reservoir 5 containing a non-combustible coating 4. 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.
