The present invention relates to a construction panel useful as a heat insulating board or an exterior wall for construction, and a method for manufacturing the same. As thermal insulation materials for buildings or architectural panels having a composite structure, there are, for example, a composite structure in which polyurethane foam is sandwiched between colored iron plates, or a composite board in which phenol foam is integrally bonded to a steel plate or the like with glue or the like. However, in the case of the former, the biggest drawback is that it is a combustible material and may emit smoke, carbon monoxide, or harmful gases, so there are many regulations in place when using it as a building material. In the latter case, the iron plate and the phenol foam could not be bonded together reliably and easily, and the nonflammable property could not be fully utilized. Furthermore, although phenol foam has excellent fire resistance, it has the disadvantage of low impact strength, so-called brittleness, and its use as such has been subject to many limitations. The present invention proposes a construction panel that eliminates these drawbacks and allows more effective use of phenol foam, and a method for manufacturing the same. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a construction panel and a method for manufacturing the same according to the present invention will be described in detail below with reference to the drawings. Figure 1 shows a synthetic resin foam layer (hereinafter simply referred to as a synthetic resin foam layer) 2 made of one of polyurethane foam, polyurethane elastomer, and polyisocyanurate foam on both sides of a phenol foam 1, which is coated with waterproof paper or a thin metal plate. This figure shows a construction panel in which a sheet-like material (hereinafter simply referred to as a sheet-like material) 3 is fixed together. The above phenol foam 1 has compressibility, fire resistance, and non-smoke property, and has a thickness and density (Kg/m 3 ).
is arbitrary, but for example, the thickness is 10 to 100 mm and the density is 30
~150. The synthetic resin foam layer 2 has self-adhesive properties and impact resistance (cushion properties), and its main purpose is to function as an adhesive and a shock-resistant cushioning material. Therefore, the thickness of the foam layer is 2 to 10 mm, and the foaming ratio is 1 to 50 times. A secondary function of the synthetic resin foam layer 2 is that it can be filled and integrated regardless of the surface condition of the phenol foam 1 and the back surface structure of the sheet-like material 3. The sheet material 3 may include asbestos paper, kraft paper, synthetic resin sheet, glass fiber nonwoven fabric, asphalt felt,
It is made of one or more types of waterproof paper made of terfelt, metal foil, etc., or thin metal plates, and is provided to improve mechanical strength. In addition, when the sheet-like object 3 is formed of a metal plate and a waterproof sheet, the surface of the thin metal plate may be embossed, or the cross-sectional shape may be bent and formed into a shape according to various purposes. be. Next, a method for manufacturing a construction panel according to another invention will be explained using FIG. 2. First, it is assumed that a sheet-like material 3, for example, a metal hoop material 4, is molded using a molding machine (not shown) to have the cross-sectional shape shown in FIG. Next, through a process of continuously supplying this molding material, a discharge process of uniformly and thinly discharging a synthetic resin raw material 6 made of unfoamed polyurethane foam into the recess 5, and a discharge process of the discharged synthetic resin raw material 6 in the middle of reaction. The phenol foam 1 is then supplied to the recess 5 and transferred to a phenol foam supply step where it is inserted. On the other hand, a synthetic resin raw material 6 made of cream thyme-like polyurethane foam mixed into a sheet material 3 (asbestos paper) is discharged almost uniformly, gradually reacts, and when gel time is reached, it is brought into contact with the phenol foam 1 and laminated. After a lamination process, the material is sent to a curing oven (furnace) consisting of steel belts 7 and 8 and a heating device 9, and heated and pressurized in this oven to give it an apparent hardening process. The product is taken out from the outlet. In this case, the temperature inside the furnace is 50-100℃,
The curing time is about 1 to 5 minutes. It is also possible to discharge the synthetic resin raw material 6 onto the phenol foam 1 through the nozzle N at the position shown by the dashed line in FIG. Here, the condition of the architectural panel according to the present invention will be compared and examined with conventional products. The following items were prepared as test pieces. The architectural panel according to the present invention has a density of 40 kg/m 3 as shown in FIG.
Phenol foam 1 has a thickness of 20 mm, the thickness of the synthetic resin foam layer 2 is 4 mm, and the density is 30 Kg/m 3 , one sheet-like material 3 is made of kraft paper 3b subjected to waterproof treatment, and the other sheet-like material 3 is A colored iron plate 3a with a thickness of 0.27 mm was used. The case where the synthetic resin foam layer 2 covers the entire outer periphery of the phenol foam 1 is shown. The conventional product is a composite board in which Phenol Foam 1 is sandwiched between a colored iron plate 3a and kraft paper 3b and integrated with a synthetic resin adhesive, and its density and thickness are the same as the Phenol Foam 1 used in the product of the present invention. I took it as a thing.

Visual inspection of a 1.5Kg weight dropped from a height of 1.5m. What is brittleness?ASTM-C-421-61
I used this method. The conformability and smoke generation properties of the surface material when combined with the unevenness of the surface material, such as the embossed colored iron plate 3a, were determined according to the method of ASTM-D-2843-70. The member according to the present invention exhibits outstanding water resistance because the skin layer of the synthetic resin foam layer 2 is sufficiently formed. As described above, according to the architectural panel and the manufacturing method thereof according to the present invention, a sheet material is adhered to both sides of a phenol foam via a synthetic resin foam layer made of one of polyurethane foam, polyurethane elastomer, and polyisocyanurate foam. Therefore, since the synthetic resin foam layer functions as an adhesive, no other adhesive is required. Since the synthetic resin foam layer has cushioning properties, it overcomes the fragility of phenol foam and provides a construction panel with strong impact resistance. Since sheet-like materials are formed on both sides, the mechanical strength as a construction panel is improved. The weakest point of the phenol foam, which has excellent compression resistance, fire resistance, and non-smoke property, is protected by the synthetic resin foam layer, and the performance of the phenol foam can be utilized. The above-mentioned construction panels have excellent impact resistance, compression resistance, fire resistance, and non-smoking properties, as well as excellent mechanical strength. It is easy to manufacture and can be produced continuously. It has the following effects and characteristics.
