Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a fire prevention and heat insulation panel using a synthetic resin foam as a core material, particularly a foam that has a possibility of passing as a quasi-noncombustible material. [Prior art] A conventional panel of this type is Utility Model Application No. 52-134217.
Publication No. 138312/1983, Japanese Patent Application Laid-Open No. 1983-138312
-25649, and Japanese Utility Model Application Publication No. 61-56414 are known. [Problem to be solved by the invention] However, the panel of the first publication has a lattice-shaped honeycomb interposed between the front and back face plates, and the upper and lower layers of the honeycomb are made of phenolic foam insulation material, and the middle layer is made of foamed metal. Since the panel is integrally formed with powder interposed therebetween, the manufacturing process is extremely multi-step, complicated, and expensive, and furthermore, it is a panel that cannot be produced continuously. Of course, when polyurethane foam is used as an insulating material, it cannot pass the quasi-noncombustible material and fireproof structure tests, and even when phenol foam is used, it is difficult depending on the foam, and on top of that, it is a weak point of phenol foam. There was a disadvantage that the weak adhesive force and brittleness reduced the strength of the entire panel. Also,
The second honeycomb structure has phosphoric acid first added to the honeycomb core.
These panels are injected with an inorganic foam insulation material such as aluminum, phosphoric acid, or talc as a core material, and have excellent heat insulation, fire resistance, compressibility, and soundproofing properties. Because of the presence of adhesive, it lacks strength as an integrated product, and has the disadvantages of increased cost and poor productivity. Furthermore, the third panel has a structure in which the cells of the honeycomb core are filled with resin foam, and the resin foam and honeycomb core are bonded to the front and back materials, increasing the adhesive strength between each member. , and the heat insulating properties of the resin foam act between the honeycomb core, front and back materials, preventing peeling between each member and increasing the strength of the entire panel, but fire resistance cannot be expected at all, and the honeycomb-like It was difficult to uniformly fill the honeycomb with resin foam. Furthermore, the fourth panel is a construction board with reinforcing members (flat steel, shaped steel, corrugated steel) embedded inside the foamed synthetic resin board to provide bending strength.
The reinforcing member is a major weakness in terms of fire protection and heat insulation, and the reaction during resin foaming is directly affected. In addition, in resin foam, the air inside the cells expands due to sunlight.
The force that deforms the foam is strong, and deformation of a composite plate using the foam as a core material is unavoidable.

[Means to solve the problem]

The present invention is a semi-incombustible material, a synthetic resin foam that can be used as a core material for a fireproof structure, and an engineering plastic net-like body as a reinforcing material formed into peaks, valleys, various cores, etc., and interposed integrally therewith. Sand-inched, lightweight, insulating,
It has excellent fire retardancy and productivity, and has excellent wetting and bonding of the resin foam raw material and reinforcing material. It also passes the above tests, and the panel does not become uneven even when heated to about 130°C by sunlight. This project proposes a fireproof insulation panel that does not deform. [Example] Below, using drawings, fire prevention and insulation panels according to the present invention (
An example (hereinafter simply referred to as a panel) will be described in detail. FIG. 1 is a perspective view showing an example of the above-mentioned panel, in which soil is the panel, 2 is a surface material, 3 is a back material, soil is a core material, and is composed of foamed N5 and a skeleton material 6. To explain further,
The panel is a sandwich structure with a core material interposed between the front and back materials, and the thickness is 10 to 200 m.
Let it be m position. In other words, the front and back materials 2.3 have a thickness of 0.2~

It is formed into a predetermined shape by roll forming or the like. Of course, the plate material may be either a flat plate or an embossed plate. The core material soil has a structure in which a skeleton material 6 is integrally interposed in foamed N5, and the foamed layer 5 is a type of polyisocyanurate foam or phenol foam, and is a quasi-noncombustible material and fireproof material that can pass the fireproof structure. Made from materials with performance. In addition, the skeleton material 6 is made of engineering plastic (hereinafter simply referred to as engineering plastic) and is formed into one type of shape such as a net shape, a roll shape, a curl shape, a cardboard shape, etc. The material 6 may be buried, built-in, or placed as shown in Figure 1, and the front and back materials 2
．． 3 and the frame member 6 are interposed so as to have a strength that makes them come into contact with each other. In other words, engineering plastic raw materials include PPS (polyphenylene sulfite) and PES (polyetherketone).
, PAR (borea relay)), PAMXD6 (nylon), PEEK (polyetherketone), PEI (
polyether polymer), PI (polyimide), PVD
One type of F (thermoplastic fluororesin) is molded into the above-described shape. For example, as shown in FIG. 2, a net-like sheet is formed with alternating peaks, valleys α and β, and a curved surface. The enlarged view shows a small band shaped like the one shown in FIG. 3 into the shape of mountains and valleys. In particular, this framework material 6 does not reduce the fireproofing properties and foaming properties of the foam layer 5, and also has the function of suppressing the deformation of the panel top even at temperatures caused by sunlight, and serves as a function to prevent the foam layer 5 from cranking under high heat. be. Next, as a manufacturing method for the above panel, PE is applied on the back material 3.
Using S as a material, a framework material 6 having a thickness of 0.5 mm+, a width of 3 squares, and a lattice spacing of 10 mm was formed into peaks and valleys, and the material for the foam layer 5 was discharged in liquid form onto this. Next, surface material 2
