Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof / soundproof panel (hereinafter simply referred to as a panel) in which a core material is sandwiched between a metal surface material and a back surface material.

[0002]

2. Description of the Related Art Heretofore, as a sandwich panel of this kind, (a) a front panel, a panel in which only a core material made of a synthetic resin foam layer is interposed between back surface materials, and (b) a synthetic resin foam layer of the core material are used. There are many panels including a mixture of lightweight aggregates, (c) a panel formed of an inorganic foam layer instead of the synthetic resin foam layer as the core material, and the like.

[0003]

However, these panels have various inconveniences, for example, in (a), they are lightweight but poor in heat resistance, fire resistance, and sound insulation.
In the case of (b), the lightweight aggregate interposed in the synthetic resin foam layer is
There is a problem of lowering the adhesive strength between the front and back materials and the synthetic resin foam layer. In the case of (c), the fire resistance is outstanding, but the mechanical strength (bending, cutting, impact), etc. is lacking and the panel itself. However, there is a drawback that it is difficult to handle and the workability is poor.

[0004]

In order to eliminate such drawbacks, the present invention densely fills a foam layer with a lightweight aggregate to improve fire resistance and fire resistance, and further interposes a lead layer in the foam layer. The present invention proposes a panel in which the soundproofing property of the panel is improved and the adhesive strength between the foam layer and the front and back materials is enhanced by the non-woven fabric which is adhesively interposed between the front and back materials.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the panel according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory view showing the panel A, and the panel A has a front material 1 and a back material 2 sandwiching a core material 3. Explaining further, the front surface material 1 and the back surface material 2 are made of metal thin plates and are formed by roll molding, extrusion molding, or the like.

A sheet-shaped non-woven fabric 4 is adhered to the surface of the surface material 1 and the back surface material 2 on the side of the core material 3. The non-woven fabric 4 is made of, for example, polyester, nylon, boron or carbon. It is formed from a sheet-like material composed of alumina-based, silicon carbide-based, and aramid-based fibers. Further, the non-woven fabric 4 is a surface material 1 and a back surface material 2 and a core material 3 described later.
It has the functions of strengthening the adhesiveness with, improving the mechanical strength of the panel A, and improving the flatness of the front surface material 1 and the back surface material 2.

The core material 3 comprises a foam layer 5 and a lead layer 6 interposed in the foam layer 5. That is, the foam layer 5 is a layer in which the lightweight aggregate 7 is closely packed and the synthetic resin foam 8 is used as the binder thereof, as shown in FIG.
The foam layer 5 functions as a heat insulating material, an adhesive material, a reinforcing material, a soundproof material, a cushioning material, a fireproof material, and a fireproof material.

The lightweight aggregate 7 is made of pearlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, etc., which improves the fire resistance and fire resistance of the foam layer 5 and also has the mechanical strength of the panel A. To improve.
In FIG. 2, pearlite grains having a diameter of about 5 to 30 mm are used as the lightweight aggregate 7.

The synthetic resin foam 8 is made of polyisocyanurate foam, phenol foam, polyimide foam, vinyl chloride foam, or the like. In FIG. 2, the synthetic resin foam is used in order to obtain the panel A that passes the fireproof structure 1 hour test. Phenol foam is used as 8.

Further, as the foam layer 5, as shown in FIGS.
It can also be formed as shown in (d). That is, FIG. 3A shows the foam layer 5 in which the lightweight aggregate 7 is densely packed with pearlite particles 7a having a large particle diameter and pearlite particles 7b having a small particle diameter to increase the density. FIG. 3B shows a foam layer 5 in which pearlite particles 7a as the lightweight aggregate 7 and expansive graphact 7c that expands and foams at high temperature are mixed to improve fire resistance. FIG. 3 (c) uses perlite particles 7d coated with a super absorbent polymer as the lightweight aggregate 7, and adsorbs condensed water generated when the raw material is cured when phenol foam is used as the synthetic resin foam 8. The foam layer 5 is capable of holding and improving the fire resistance due to the water content thereof and shortening the curing time during manufacturing. Figure 3
(D) is a lightweight aggregate 7, which is a foam layer 5 in which pearlite grains 7a and glass fibers 7e such as chopped strands are interposed to improve fire resistance and strengthen the bending strength of the panel A.

The lead layer 6 is interposed in the foamed layer 5 and mainly functions as a soundproofing material and a reinforcing material. In addition to the honeycomb structure as shown in FIG. 1, the lead layer 6 has a flat plate shape as shown in FIG. 4A, a lattice shape as shown in FIG. Lath-shaped lead layer 6 as shown
Can be The lead layer 6 can be interposed at any position in the foam layer 5, and can be used in a double or triple layer or in combination.

5A to 5C and 6 are explanatory views showing an example of the shape of the panel A according to the present invention.
5A and 5B are a panel A having male and female fitting structures, and FIG.
FIG. 6 shows a block type panel A.

[0013]

As described above, according to the panel of the present invention, since the lightweight aggregate is mixed in the foam layer of the core material, the panel is excellent in both fire resistance, fire resistance and heat insulation, and at the same time, the panel is excellent. The mechanical strength of can be improved. Since the lead layer is interposed between the foamed layers of the core material, the soundproofing is improved and the panel is further reinforced. The sheet-shaped non-woven fabric which is adhered to the front and back materials improves the adhesive strength between the front and back materials and the core material, and keeps the front and back materials flat and increases dimensional stability. Since a lightweight aggregate and a lead layer are interposed in the core material, the amount of synthetic resin used is reduced, leading to cost reduction. Light weight, easy to handle, and excellent in workability. There are features and effects.
