Description

  The present invention relates to a fireproof panel used for an exterior of a building.

  Until now, as a fireproof panel used for building exteriors, as a technology that intervenes phenol foam and inorganic board mixed with inorganic material between the front and back materials made of long metal material, patent There is a technique described in No. 3306439 (Patent Document 1).

Japanese Patent No. 3306439

However, in the technology of Patent Document 1, in order to ensure fire resistance, a phenol foam containing an inorganic board layer and mixed with an inorganic material is provided between a front surface material and a back surface material made of a long metal material. and it is interposed, phenol foam density had to be formed on ^{50kg / m 3 ~300kg / m 3} . For this reason, there is a problem that the panel weight increases, the workability deteriorates, and the heat insulating property decreases.

  This invention solves the said subject, The place made into the objective is 2 layers including an organic heat insulation panel layer and an inorganic board layer at least between the surface material which consists of a elongate metal material, and a back surface material. The purpose is to reduce the panel weight, improve the workability, and greatly improve the heat insulation of the long fire-resistant panels laminated and bonded.

The fireproof panel according to the present invention for achieving the above-mentioned object is a long-shaped sheet having two layers including at least an organic heat insulating panel layer and an inorganic board layer between a front surface material and a back surface material made of a long metal material. in the refractory panels, the organic insulating panel layer is composed of pre sides nonwoven fabric on both surfaces are molded integrally laminated density of phenolic foam insulation panels of ^{20kg / m 3 ~49kg / m 3} .

In particular, the surface of the phenolic foam insulation panels layer, nonwoven fabric is laminated and integrated, the surface material through the nonwoven fabric, wherein the rear material, or laminated bonded to an inorganic board.

According to the fireproof panel according to the present invention, in a long fireproof panel in which two layers including at least an organic heat insulating panel layer and an inorganic board layer are laminated and bonded between a front surface material and a back material made of a long metal material. as the organic insulating panel layer by density composed phenolic foam insulation panels in advance on the surface the nonwoven fabric is molded integrally laminated in ^{20kg / m 3 ~49kg / m 3} , the panel weight lighter, While improving the workability, it is possible to greatly improve the heat insulation.

Moreover, during the production of refractory panels, such that the density is ^{20kg / m 3 ~49kg / m 3} , to prepare a phenolic foam material, it is ejected, the reaction foamed, if the panels molded in phenolic foam, the reaction Condensed water at the time of the maintenance of several tens of percent of the weight, and after the product curing period or after the panel construction, due to changes in the outside air temperature, etc., the water vaporizes and there is no escape route. The refractory panel has an adverse effect on the fireproof panel over time, such as remaining on the inside and the surface of the fireproof panel swells or warps.

  Furthermore, in the case of the phenol foam prepared at such a low density, since the curing shrinkage becomes large, the refractory panel is indented and warped, and the dimensional accuracy of the panel cannot be ensured. In the fireproof panel according to the present invention, the organic heat insulation panel layer can be subjected to heat curing at the time of manufacturing the phenol foam heat insulation panel, and the condensed water at the time of the phenol foam reaction can be diffused in advance. Due to changes in the outside temperature, etc., during the panel curing period or after panel construction, the moisture is vaporized and there is no escape route, so it remains inside the surface material of the fireproof panel, and the fireproof panel surface swells or warps. It is possible to avoid adversely affecting the fireproof panel over time.

  In addition, the curing shrinkage of phenol foam formulated at low density, even if molded in advance as a phenol foam insulation panel, causes curing shrinkage evenly in the length / width / thickness direction, resulting in flatness. It is possible to laminate and bond a certain phenol foam heat insulating panel, and it is possible to avoid a problem that the dimensional accuracy of the panel cannot be ensured due to a dent or warp in the fireproof panel.

Thus, in advance, by the density produced with the intention of weight and thermal insulation used to adhere the phenolic foam insulation panels of ^{20kg / m 3 ~49kg / m 3} , on which avoids such problems , Weight reduction and heat insulation can be improved.

  In addition, the phenol foam heat insulation panel used as an organic heat insulation panel layer comprises 80% or more of the whole weight with an organic material. If it is a small amount of 20% or less, it is possible to reduce the weight and improve the heat insulating property even if an inorganic material is included. However, from the viewpoint of weight reduction and improvement in heat insulation, the organic material ratio is preferably large, preferably 90% or more, and more preferably 95% or more.

Moreover, despite the density intended for such weight reduction and heat insulation improvement is adhered by laminating phenolic foam insulation panels of ^{20kg / m 3 ~49kg / m 3} , by laminating at least an inorganic board layer Therefore, it is possible to ensure the fire resistance of the fireproof panel. That is, with a panel thickness of about 50 mm to 60 mm, it is possible to ensure performance for 1 hour of fire resistance. In addition, with a panel thickness of about 35 mm to 40 mm, it is possible to ensure a fire resistance performance of 30 minutes. In addition, it is possible to ensure predetermined | prescribed fireproof performance by comprising the both-ends part used as the weakest point part of fireproof performance by the edge part shape not shown here. For example, an inorganic fireproof member can be processed and fitted in accordance with the shape of the male connecting portion or the female connecting portion to ensure a predetermined fireproof performance.

For example, during the production of refractory panels, such that the density is ^{20kg / m 3 ~49kg / m 3} , to prepare a phenolic foam material, by reacting foam, the surface material, by the adhesion between the backing material or an inorganic board, In such a case, the adhesive strength is weak, and there is a drawback that the end portion of the surface material, the back surface material, or the inorganic board, particularly the surface material, peels off with a slight impact.

In contrast, according to the fire panel according to the present invention, the surface of the phenolic foam insulation panels layer, nonwoven fabric laminated, phenolic foam is integrated entangled with the fibers constituting the nonwoven fabric, said non woven fabric through the surface material, because it is laminated and adhered to the back sheet or an inorganic board, and the fibers constituting the nonwoven fabric, to secure entangled more adhesive, phenolic foam insulation panels and the surface member, the rear surface It is possible to improve the adhesive force with the material or the inorganic board, and to prevent the disadvantage that the end portion with the surface material in particular is peeled off against the impact.

Of course, also in the phenolic foam insulation panels layer, since the phenol foam is integrally entangled with the fibers constituting the nonwoven fabric, there is no peeling problem of the interface between the phenolic foam and the nonwoven fabric.

According to the fireproof panel according to the present invention, in a long fireproof panel in which two layers including at least an organic heat insulating panel layer and an inorganic board layer are laminated and bonded between a front surface material and a back material made of a long metal material. as the organic insulating panel layer by density composed of 20kg / m ³ ~49kg / m ³ surface phenolic foam insulation panels with material, the panel weight lighter, as well as improve the workability, significantly thermal insulation It can be improved.

Further, the surface of the phenolic foam insulation panels layer, nonwoven fabric laminated, phenolic foam is integrated entangled with the fibers constituting the nonwoven fabric, the surface material through the nonwoven fabric, the back surface member, or inorganic because it is laminated and adhered to the board, the fibers constituting the nonwoven fabric, to secure further adhesive tangled, phenolic foam insulation panels and the surface material, to improve the adhesion between the back surface material or an inorganic board, peeling It is possible to prevent the drawbacks.

  The embodiment of the fireproof panel according to the present invention will be specifically described with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing a typical embodiment of a fireproof panel according to the present invention, and FIGS. 2 and 3 are partially cutaway perspective views showing other embodiments of the fireproof panel according to the present invention. is there.

  FIG. 1 shows three layers of a surface-side organic heat insulation panel layer 4, an inorganic board layer 5, and a back-side organic heat insulation panel layer 6 in this order between a surface material 2 and a back material 3 made of a long metal material. A partially cut perspective view in which a long refractory panel 1 which is laminated and bonded and has a male connecting portion 7 and a female connecting portion 8 provided on both end portions 10 is cut perpendicularly to both end portions 10 and drawn. FIG.

  The width (working width) of the fireproof panel 1 is 910 mm or 600 mm, and in FIG. 1, in order to enlarge and draw the vicinity of the side end portions 10, the center portion of the panel width is omitted from the illustration. The thickness of the fireproof panel was 50 mm (or 60 mm).

Here, the front-side and back-side organic heat insulation panel layers 4 and 6 are composed of a phenol foam heat insulation panel having a density of 27 kg / m ³ and a thermal conductivity of 0.020 W / m · K and almost no inorganic material. A synthetic fiber (polyethylene terephthalate) nonwoven fabric 9 is laminated and integrated on the surface, and is laminated and adhered to the surface material 2, the back material 3, and the inorganic board 5 via the nonwoven fabric 9. Although the synthetic fiber was used as the nonwoven fabric 9, other than that, as the inorganic fiber, for example, glass pulp mixed paper using glass fiber, glass nonwoven fabric or the like may be used. Although not shown, the adhesive was bonded with an epoxy adhesive.

  The inorganic board 5 was a gypsum board, and was arranged at the approximate center of the panel thickness.

  In order to ensure fireproof performance, an inorganic fireproof member (fiber-mixed calcium silicate plate) is processed and fitted to both end portions 10 in accordance with the shape of the male connection portion 7 or the female connection portion 8. And configured.

As in this example, the front and back side organic heat insulation panel layers 4 and 6 are phenol foam heat insulation with a density of 27 kg / m ³ , a thermal conductivity of 0.020 W / m · K and almost no inorganic material. Since the panels were laminated and constructed, the panel weight was reduced, the workability was improved, and the heat insulation was greatly improved.

  Moreover, since the condensed water at the time of the phenol foam reaction has been diffused in advance, moisture is vaporized due to a change in the outside temperature or the like due to the curing period of the refractory panel 1 or after the construction of the refractory panel 1. Therefore, it is possible to avoid adverse effects on the fireproof panel 1 over time, such as remaining inside the surface material 2 of the fireproof panel 1 and causing the surface of the fireproof panel 1 to swell or warp. .

Furthermore, even though it is a phenol foam formulated at a low density of 27 kg / m ³ , it is molded in advance as a phenol foam insulation panel, so it cures and shrinks evenly in the length, width, and thickness directions. As a result, it was possible to laminate and adhere as a phenol foam heat insulation panel with flatness, and the refractory panel 1 did not dent or warp, thereby avoiding the problem that the dimensional accuracy of the panel could not be ensured.

  The phenol foam heat insulation panel here contains almost no inorganic material, and 99% or more of the weight ratio is an organic material.

  On the other hand, since the phenol foam heat insulation panel in which the nonwoven fabric 9 is laminated and integrated is used as the front and back side organic heat insulation panel layers 4 and 6, the phenol foam is integrated with the fibers constituting the nonwoven fabric 9, Since it is laminated and bonded to the surface material 2, the back surface material 3 and the inorganic board 5 through the nonwoven fabric 9, an adhesive (not shown) is further entangled and fixed to the fibers constituting the nonwoven fabric 9. Adhesive strength between the panel and the surface material 2, the back surface material 3, and the inorganic board 5 was improved, and in particular, it was possible to prevent the drawback that the end portion of the surface material 2 was peeled off against an impact.

  FIG. 2 shows an embodiment constituted by two layers of a surface side organic heat insulating panel layer 4 and an inorganic board layer 5. FIG. 3 shows an embodiment constituted by two layers of an inorganic board layer 5 and a back side organic heat insulating panel layer 6.

As shown in FIG. 2 and FIG. 3, even if either the front-side organic heat insulation panel layer 4 or the back-side organic heat insulation panel layer 6 is omitted, the panel thickness is about 50 mm (60 mm) from the building size. It is possible to ensure the performance for 1 hour of fire resistance. However, density of phenolic foam insulation panels of ^{20kg / m 3 ~49kg / m 3} , in the case of forming the surface-side organic insulation panel layer 4 or the rear surface side organic insulating panel layer 6, panel thickness 50 mm (60 mm) degree The inorganic board layer 5 is indispensable in order to secure the performance of 1 hour of fire resistance with the dimensions of As the inorganic board 5, besides a gypsum board, a calcium silicate board, a calcium carbonate board, a pearlite cement board, a rock wool board, a slate board, and other inorganic materials can be used.

  Thus, if the fireproof panel 1 is formed by laminating and bonding at least two layers including the inorganic board layer 5, the panel weight is reduced and the heat insulation is greatly improved as in the three-layer embodiment shown in FIG. I can do it. Similarly, problems such as swelling caused by residual phenol foam condensed water and problems such as panel dents caused by phenol foam curing shrinkage can be solved.

  As an application example of the present invention, it can be suitably used as a fireproof panel used for an exterior of a building.

It is a partially cutaway perspective view showing another embodiment of the fireproof panel according to the present invention. It is a partially cutaway perspective view showing another embodiment of the fireproof panel according to the present invention.
