Hereinafter, the present invention will be described in more detail using embodiments.

[First Embodiment]
The fireproof panel 1 according to the first embodiment of the present invention, as shown in FIG. A foam layer 20 is provided, and the panel material 10 and the fireproof and heat insulating foam layer 10 form a laminated structure. In the fireproof panel 1 according to the first embodiment of the present invention, a fireproof heat insulating foam layer 20 is laminated on one surface of the panel material 10 . The fireproof and heat insulating foam layer 20 is preferably laminated directly on one surface of the panel member 10 .
Examples of partitions of a building on which the fireproof panel 1 according to the first embodiment of the present invention is provided include outer walls, inner walls, floors, ceilings, roofs, and the like, preferably outer walls.

The fireproof panel 1 has heat-shielding and flame-shielding properties when heated by a fire or the like, and has excellent fire resistance. "Heat shielding property" refers to the performance that the temperature of the non-heated surface does not rise above the combustion temperature of combustibles. “Flame-blocking property” refers to the ability to prevent flames from being generated on non-heated surfaces.
As a fire resistance test of the fire-resistant panel 1, the fire-resistant panel 1 was installed in front of the wall furnace and the temperature inside the furnace was heated so as to follow the standard heating temperature curve of ISO834. do. Specifically, the fireproof panel 1 is particularly required to be fireproof when heated for 30 to 60 minutes due to a fire or the like. Judge the heat and flame barrier properties after and after 60 minutes. The fireproof panel 1 is heated along the standard heating temperature curve of ISO834 in order to support the certification of the fireproof structure specified in Article 2, Item 7 of the Building Standards Law or Article 112, Paragraph 2 of the Enforcement Order of the Building Standards Law. 30 minutes and 60 minutes after performing the above, it is preferable to satisfy all the judgments of heat insulation and flame insulation.

Examples of the panel material 10 include aluminum panels, steel panels, glass panels, concrete panels, lightweight cellular concrete (ALC) panels, extruded cement panels (ECP), and ceramic sidings. Since the fireproof panel 1 according to the first embodiment has a form in which the fireproof and heat insulating foam layer 20 is laminated on one surface of the panel material 10, it is other than the glass panel in which it is difficult to laminate the fireproof and heat insulating foam layer 20. is preferred. Specifically, the panel material 10 is preferably an aluminum panel or an ALC panel, more preferably an aluminum panel, from the viewpoint of having high fire resistance and light weight.

The thickness of the panel material 10 is preferably 0.1 mm or more, more preferably 0.3 mm or more, and even more preferably 5.0 mm or more. The thicker the panel material 10, the more improved the fire resistance. It can have high fire resistance because the thickness of the panel material 10 is more than the said lower limit.

(Fireproof insulation foam layer)
The fire-resistant and heat-insulating foam layer 20 is made of a fire-resistant and heat-insulating foam. In addition, the fireproof and heat-insulating foam layer 20 forms a carbonized layer when heated during a fire. By forming a carbonized layer when the fireproof insulation foam layer 20 is heated, it exhibits heat shielding and flame shielding properties, and the carbonized layer can suppress a decrease in heat insulation even in the event of a fire, etc., and the fireproof panel 1 of fire resistance can be maintained.

The fireproof and heat insulating foam layer 20 is preferably made of flame-retardant urethane foam. Specific commercial products of flame-retardant urethane foam include "PUXFLAME" (manufactured by Sekisui Chemical Co., Ltd.).

As shown in FIG. 2, the fireproof and heat insulating foam layer 20 may have a mesh material 21 therein. When the fireproof and heat insulating foam layer 20 is heated, it shrinks thermally and generates a resin tensile force, which may cause cracks and a decrease in heat insulating properties. By setting it as the internal structure, the crack of the fireproof insulation foam layer 20 can be suppressed and the fall of thermal insulation can be suppressed.
In addition, since the fireproof insulation foam layer 20 has a structure in which the mesh material 21 is included, the mesh material 21 is supported by the support part of the building, so that when a fire occurs, the fireproof insulation foam becomes a carbonized layer. The layer 20 is supported by the supporting portion via the mesh material 21, and is prevented from dropping, thereby maintaining fire resistance.
The mesh material 21 may be any material that has a plurality of through-holes. Examples thereof include wire mesh, glass mesh, glass cloth, punching metal, and welded steel bars, with wire mesh being preferred.

INDEX = number of equivalents of isocyanate / (number of equivalents of polyol + number of equivalents of water) x 100
here,
Number of equivalents of isocyanate = number of parts of polyisocyanate used x NCO content (%) x 100/NCO molecular weight number of equivalents of polyol = OHV x number of parts of polyol used / molecular weight of KOH, OHV is the hydroxyl value of polyol (mgKOH/g),
Equivalent number of water=number of parts of water used×number of OH groups of water/molecular weight of water. In the above formula, the unit of the number of parts used is weight (g), the molecular weight of the NCO group is 42, and the NCO content is the ratio of the NCO group in the polyisocyanate compound expressed in mass%.
