Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fireproof and heat-insulating panel having a core of a synthetic resin foam which is likely to pass a semi-incombustible material.

[Conventional technology]

As conventional panels of this type, Japanese Utility Model Laid-Open No. 52-134217, Japanese Patent Laid-Open No. 52-13383, Japanese Patent Laid-Open No. 62-25649, and Japanese Utility Model Laid-Open No. 61-56414 are known.

[Problems to be solved by the invention]

However, in the panel of the first publication, a lattice-like honeycomb is interposed between both the front and rear plates, and the upper layer of the honeycomb,
Because the panel is integrally formed by interposing phenol foam insulation material in the lower layer and foamed metal powder in the middle layer, the production is extremely multi-step, complicated and expensive, and furthermore, the panel cannot be continuously manufactured. is there. Of course, when polyurethane foam is used as the heat insulating material, it cannot pass each test of the quasi-incombustible material and the fire prevention structure, and when using phenol foam, it is difficult depending on the foam. Moreover, it is a weak point of phenol foam. There is a disadvantage that the weak adhesiveness and the brittleness lower the strength of the entire panel. Also,
The second honeycomb structure has phosphoric acid first added to the honeycomb core.
Panels infused with inorganic foaming heat insulating material such as aluminum, phosphoric acid, and talc as the core material.Excellent heat insulation, fire resistance, compressibility, and soundproofing. Because of the interposition of the adhesive, there was a disadvantage that the strength as an integral product was lacking, and that the cost was increased and the productivity was poor. Further, the third panel has a structure in which the cells of the honeycomb core are filled with a resin foam, and the resin foam and the honeycomb core are bonded to the front and back materials, so that the adhesive force between the members increases. And, the heat insulating property of the resin foam acts between the honeycomb core, the front surface and the back surface material, and there is no separation between the members,
Although the strength of the entire panel is increased, fire protection cannot be expected at all, and it is difficult to uniformly fill the resin foam with the honeycomb honeycomb. Further, the fourth panel is a construction plate material in which a reinforcing member (flat steel, mold steel, corrugated sheet) for imparting bending strength is embedded inside the foamed synthetic resin plate, but the reinforcing member is large in terms of fire protection and heat insulation. Weakness,
In addition, there is a disadvantage that the reaction at the time of resin foaming is directly affected. Further, in the resin foam, the air in the cell expands due to sunlight, and the force for deforming the foam is strong, so that the deformation of the composite plate using the foam as a core material is inevitable.

[Means for solving the problem]

The present invention relates to a semi-combustible material, a synthetic resin foam which can be a core material of a fireproof structure, a reinforcing net made of an engineering plastic mesh formed on a mountain, a valley, various cores, etc., and integrally interposed, and a front and back material. Sandwich, lightweight, excellent in heat insulation, fire protection, productivity, and excellent in wetting and integration of resin foam raw material and reinforcing material, and passed each of the above tests. The present invention proposes a fireproof and heat-insulating panel in which the panel is not deformed into irregularities even when heated.

〔Example〕

Hereinafter, an embodiment of a fire prevention and heat insulation panel (hereinafter, simply referred to as a panel) according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an example of the above-mentioned panel. 1 is a panel, 2 is a front surface material, 3 is a back surface material, and 4 is a core material, which is composed of a foam layer 5 and a skeleton material 6. More specifically, the panel 1 is a sandwich structure in which the core member 4 is integrally interposed between the front and back members 2 and 3 and has a thickness of 10 to 200 mm.
Rank. That is, the front and back members 2 and 3 are metal plates having a thickness of about 0.2 to 3 mm, for example, Al, Fe, Cu, stainless steel, aluminum / zinc alloy-plated steel plate, titanium alloy plate, color steel plate,
It is formed by press-forming, extruding, roll-forming, or the like, a predetermined type of a galvalume steel plate, a galfan, an enameled steel plate, a fluororesin-coated steel plate, a clad steel plate, a sandwich steel plate, or the like. Of course, the plate material may be a flat plate or an embossed plate. The core material 4 has a structure in which a skeleton material 6 is integrally interposed in a foam layer 5, and the foam layer 5 is one of polyisocyanurate foam and phenol foam.
The raw material is a quasi-noncombustible material and a material having a fire protection performance that can pass the fire protection structure. The skeleton material 6 is made of engineering plastic (hereinafter simply referred to as engineering plastic) as a raw material and is formed into one type such as a net shape, a honeycomb shape, a roll-shaped curl shape, a corrugated cardboard shape, and the like. Is embedded or built in, or is disposed as shown in FIG. 1, and is interposed in such a strength that the front and back members 2 and 3 and the skeleton member 6 come into contact with each other. That is, as engineering plastic raw materials,
PPS (polyphenylene sulfite), PES (polyethersulfone), PAR (polyarylate), PAMXD6 (nylon), PEEK (polyetherketone), PEI (polyetherimide), PI (polyimide), PVDF (thermoplastic fluorine) (Resin) is formed into the shape described above. As an example, as shown in FIG.
β are formed alternately and on a curved surface. The enlarged view is obtained by molding a small band as shown in FIG. In particular, the skeletal material 6 does not reduce the fire protection and foaming properties of the foam layer 5 and also functions to prevent the panel 1 from being deformed even under the temperature of sunshine, and to help prevent the foam layer 5 from cracking under high heat. is there.

Next, as a method of manufacturing the panel 1 , PE
S is used as a material, and a skeletal material 6 having a thickness of 0.5 mm, a width of 3 mm, and a lattice spacing of 10 mm is formed into peaks and valleys, and the raw material of the foam layer 5 is discharged in a liquid state. The surface material 2 was laminated and cured to form a panel 1 having a thickness of 35 mm as shown in FIG. This panel 1 was tested for fire protection structure (JIS-A-1301).
No.), passed the semi-combustible material test (JIS-A-1321), and added the total heat value of 47,000 to the box test as an additional test.

According to the panel according to the present invention as described above, the table,
In order to interpose a core material containing a skeleton material between the back material,
There is little deformation of the panel even during sunlight. Under high heat, the foamed layer does not crack and can pass the semi-flammable and fireproof structure.
At room temperature, the mechanical strength is high. The foam layer and the skeletal material have good “slim”, low cost and high productivity. Even under high heat, there is little deformation due to the synergistic effect of the engineering plastic and the foam layer.
And so on.
