is an explanatory diagram showing the manufacturing process of the above panel, and a
As shown in the figure, a noncombustible base material 1 (hereinafter simply referred to as base material), such as a metal plate, slate board, plasterboard, etc., is fed in one direction at a constant speed via a pinch roll or the like (not shown). Next, as shown in figure b, the base material 1
A low-density nonwoven fabric 2 (hereinafter simply referred to as nonwoven fabric) is laminated on the back surface of the . This nonwoven fabric 2 has a wavy cross section and is made of glass fiber, gypsum paper, and asbestos paper, and has a density of 50 to 200 g/m 2 .Moreover, the wavy pitches are arranged on both sides of the base material 1 from the density in the center to the side edges. In addition, the material is supplied at a length that does not reach the side edges of the base material 1. Also, the height is the final height of the panel
The height H0 is larger than H1, for example, 10 to 20% higher. This process takes advantage of the fact that the raw material 3a of the synthetic resin foam 3, such as polyisocyanurate foam or phenol foam, which becomes carbide at high temperatures, rapidly changes its properties (viscosity) and volume in a short period of time. This is to create a distribution state. In addition, the nonwoven fabric 2 is formed into the final shape from the beginning, and the core material in which this is laid is unevenly distributed due to the foaming pressure and fluidity during foaming of the raw material 3, resulting in variations in the distribution density of the nonwoven fabric 2. , there is a risk of causing parts that lack fire resistance and heat resistance. Next, as shown in FIG. 1c, with the nonwoven fabric 2 layered on the base material 1, the liquid raw material 3a is distributed to the two sides of the nonwoven fabric in a so-called normal distribution, with more in the center and less towards the side edges. supply. The supplied raw material 3a rapidly undergoes a chemical reaction while passing through the rough structure of the nonwoven fabric 2, increasing the volume, viscosity, fluidity, and foaming pressure. At the initial stage of this reaction, the base material 1 (back material) is laminated as shown in Figure d, and this is fed into a mold of a predetermined shape (not shown) and foamed while regulating the height and width.
Let it harden. When foaming in this mold, the nonwoven fabric 2
The distribution density and height of the raw material 3a are uniformly distributed as shown in Fig. e by the resistance due to the fluidity foaming pressure and viscosity of the raw material 3a.

価に生産できた。 Next, in order to confirm the fire resistance and heat resistance of the panel manufactured by this manufacturing method, a test according to JIS-A-1301 was conducted, followed by observation. The results showed that the synthetic resin foam had no cracks and exhibited high heat insulation properties at high temperatures. For example, the back temperature is 25mm total thickness.
The temperature was 200° C. when the base material 1 was a 0.27 mm iron plate and the synthetic resin foam was polyisocyanurate foam (density 40 kg/m 3 ). Moreover, the amount of raw material 3a used was not much different from that in the case where nonwoven fabric 2 was not present, and production was possible at low cost.

That is, Figure a shows a panel in which a synthetic resin foam 3 formed into a special shape is present between a face material 1a formed as one side of the base material 1 as shown in the figure and a sheet-like material 1b, and Figures b and c are is foam 3
This is a panel when the is formed into a flat plate shape. In addition,
