The present invention relates to a lightweight fireproof insulation panel that exhibits high insulation performance in the temperature range from low temperatures to about 1000 degrees Celsius. Furthermore, in detail, it is lightweight as a core material, completes reaction foaming in a short time, and has an adhesive function that exhibits self-adhesive properties and fixes constituent materials when forming a foam.
Relating to a lightweight, economical, and energy-saving fire-resistant insulation panel that exhibits excellent fire resistance, heat resistance, and heat insulation by laminating a high-radiation foil on the surface of a foam that becomes a carbonized layer after burning under high heat. . Generally, a heat insulating panel has a structure in which metal plates or sheet-like materials are attached to both sides of polyurethane foam. However, this type of panel lacks fire resistance and heat resistance, and could not pass the quasi-noncombustible material test. In addition, there are panels that have improved this, such as Japanese Patent Application Laid-Open No. 55-27267, and this panel has fire and heat resistance to the extent that it passes a quasi-noncombustibility test. However, in this type of panel, the foam cannot follow the deformation of the metal plate, and the cracks in the foam become large, and most of it becomes carbonized, and the temperature on the back side increases, and the fireproof structure test (JIS-A-1301) It did not pass the test (wooden foundation) etc. In order to eliminate these drawbacks, the present invention lays out the mirror surface of the high-radiation foil so that it faces the back of the exterior material, and then laminates and integrates the core material foam and sheet-like material on top of it, making it lightweight. We aim to reduce the amount of foam raw materials used, and propose a fire-resistant and heat-insulating panel that has excellent heat insulation properties from low to high temperatures and has fire resistance that can pass fire protection structural tests. EMBODIMENT OF THE INVENTION Below, the fireproof insulation panel based on this invention is demonstrated in detail using drawing. Fig. 1 is a perspective view showing a typical example of the above-mentioned panel, and 1 is a core material, which is a foam with a closed cell structure that is highly insulating from a low temperature range to a high temperature range (approximately 1000 degrees Celsius or higher); It also functions as an adhesive for the following constituent materials during foam formation. Especially after combustion, it becomes carbide,
It has little volumetric shrinkage and cracking, has excellent shape retention, and in tests of semi-noncombustible materials, it exists in its normal form over a considerable thickness. To give specific examples, the core material 1 may be polyisocyanurate foam (including urethane-modified and phenol-modified foams), phenol foam, polyamide foam, and the like. Its thickness t is about 10~50mm, preferably 20~
30mm, the density is about 20-70Kg/ m3 . 2 is a high radiation foil body that protects the core material 1 by radiating heat from the outside. In particular, the high radiation foil body 2 has a mirror surface with a high reflectance on at least one side and a small diameter through hole 3 for bonding and integrating with other members.
This is effective in reducing heat conduction due to long-term heating from the outer surface, etc., and in facilitating integration with other members. The above-mentioned high-emissivity body 2 is an aluminum foil body or a silver foil body, and has a film thickness of about 7 to 150 microns. Further, a portion of the core material 1 passes through the through hole 3 as an adhesive, and the high radiation foil body 2 is adhered to other members without contaminating the mirror surface too much. Note that the shape of the through hole 3 (circle, square,
The shape (ellipse, diamond shape, slit shape, etc.), size (diameter), and number are arbitrary. Of course, asbestos paper, glass fiber, carbon fiber sheet, metal fiber sheet, gypsum paper, etc. may be integrally laminated on one non-mirror surface of the high radiation foil body 2. 4 is a noncombustible base material used as interior and exterior materials, and its materials include thin metal sheets (Fe, Cu, Al, stainless steel), gypsum board, slate board, molded bodies of gypsum and slag, calcium carbonate, Perlite board, calcium silicate board. Further, the cross-sectional shape of the base material 4 is not limited to a flat plate, but also includes an embossed plate and a base material coated with ricin. In particular, as a thin metal plate, a plate shaped as shown in FIGS. 2a to 2f, for example, can also be used. Note that the two-dot chain line in the figure indicates the final cross-sectional shape. Reference numeral 5 denotes the backing material, which is a sheet material laminated with the above-mentioned high-radiation foil, kraft paper, asbestos paper, gypsum paper, glass fiber sheet, synthetic resin film, or one or more of these. Preferably, the mirror surface of the high radiation foil is attached to the heating direction side. Next, an example will be explained. First, the common raw material used in each example is polyisocyanurate foam, and its blending ratio is 100 parts by weight of polyol (trade name: Hexacal).
H1 manufactured by Nippon Polyurethane Co., Ltd.), 393 parts by weight of polyisocyanurate (diphenylmethane diisocyanurate, so-called MDI), 130 parts by weight of blowing agent (trichloromonofluoromelon), 0.2 parts by weight of trimerization catalyst (potassium acetate), Foam stabilizer 3 parts by weight (product name HS-
190, manufactured by Toray Silicone), mixing time 5
seconds, cream time 12 seconds, rise time 55-60
seconds, NOC/OH=498. The structure of the panel is as shown in Figures 3a and 3b. Figure a shows a high radiation foil body 2 with asbestos paper 2b, which is made by laminating aluminum foil 2a and asbestos paper 2b together on the surface of the core material 1. It is pasted so that it is in contact with the core material, and the thickness is applied to its surface, the so-called aluminum foil 2a side.
Laminate 0.27mm color steel plates (exterior material 4). Note that the high radiation foil body 2 that contacts the exterior material 4 has a diameter of 5 mm.
Through-holes 3 of 500 mmφ/m 2 are drilled, and the core material 1
The setting is such that a part of the raw material as an adhesive, which passes through the so-called through hole 3 during the formation of the adhesive, functions sufficiently. Further, on the back side of the core material 1, a back material 5, for example, a fireproof/insulating panel made by laminating sheet-like materials made of the same material as the above-mentioned high-radiation foil body so that the mirror surface of the aluminum foil 2a is in contact with the core material 1, is used. be. Note that the high radiation foil body 2 as the backing material 5 does not require the through holes 3. In addition, Figure b shows an inner layer 5a (laminated sheet of aluminum foil 2a - asbestos paper 2b) and an outer layer 5b as the backing material 5 in Figure A.
(aluminum foil 2a - asbestos paper 2b laminate sheet) is integrated into the so-called back side of the core material 1 -
Aluminum foil 2a - asbestos paper 2b (inner layer 5
a) - Aluminum foil 2a - Asbestos paper 2b
(Outer layer 5b) is a fireproof/insulating panel laminated in the following order. Of course, the exterior material 4 and the high radiation foil body 2 have the same configuration as in Fig. a. In addition, the inner layer 5a has an outer layer 5b.
A through hole 3' is formed in a portion of the core material 1 to function as an adhesive for integration. Furthermore, as a performance test for fire resistance and heat resistance of this fire-resistant insulation panel, as shown in Fig. 4, the flame of Bunsen burner A was applied perpendicularly to the exterior material 4, and the temperature at point B on the back surface on the extension line was measured. It's about measuring.
In addition, the appearance of the foil after the test was observed from two sides of the high-emission foil with the exterior material removed. The heating curve of the Bunsen burner A is the fifth one.
As shown in the figure. Next, the test results for each example are shown in the table below.

It fully satisfies the JIS-A-1301 fire protection test standards, especially the back surface temperature of 260°C or less, and does not cause deformation or cracks that are detrimental to fire protection, so it can pass the test. What has been described above is only one example of the fireproof/insulating panel according to the present invention, and the high radiation foil 2 may be formed into a wrinkled shape, and PCP (pewatachlorophenol) may be used as a crack preventive agent in the core material to reduce smoke. Fumaric acid can also be added as an agent. Furthermore, nonflammable fibrous materials such as glass fiber, rock wool, and carbon fiber can also be added. Furthermore, the thicknesses of aluminum foil and asbestos paper can be combined in various ways, and the order of lamination with respect to the core material can be reversed. In addition, a sheet-like product laminated with aluminum foil, asbestos paper, and aluminum foil may also be used. Furthermore, a nonflammable adhesive can also be used for the high radiation foil used during lamination. In addition, a nonflammable net-like material or nonwoven fabric may be laminated on the high radiation foil 2 alone. As mentioned above, according to the fireproof insulation panel according to the present invention, even when exposed to high temperatures, the back side temperature remains at 260℃.
It has the following characteristics: fire resistance, heat resistance, and heat insulation. In addition, the high-radiation foil was placed so that its mirror surface faced the back side of the noncombustible base material, and was partially bonded to make more effective use of reflection efficiency, reducing carbonization of the core material. There are characteristics that can exist as the normal state form moves away from the flame. Furthermore, the core material is characterized by almost no cracking, small volumetric shrinkage, and, as a result, small dimensional changes. In addition, since production can be performed using almost the same process as before, new equipment is not required.
It has the advantage of being able to be produced in large quantities. In addition, it is economical because a part of the core material is used as the adhesive. Furthermore, fireproof and heat-insulating panels have excellent insulation properties under normal conditions.
