屋根材として採用される断熱パネルが製造されている。Foaming resin material is injected between metal plates such as colored galvanized iron plates, colored aluminum plates, colored aluminum-zinc alloy plated steel plates, stainless steel plates, titanium steel plates, etc., and the foamed U4 resin material is foamed by heating the metal plates. Insulating panels used as wall materials or roofing materials are manufactured by filling a foamed resin layer between metal plates to form a heat insulating board material, and cutting this heat insulating board material into predetermined dimensions.

提供することにある。Conventionally, the upper and lower metal plates are made of the same material, but for insulation panels used in food-related areas, wood drying rooms, sterile rooms, and buildings that require ultra-corrosion resistance, one metal plate is made of the same material. Not only the plate but also the upper and lower metal plates are made of materials that suit the intended use, and if expensive metal plates have to be used, this results in an increase in costs. For this reason, attempts have been made to suppress the increase in cost by making the upper and lower Jk metal plates different materials and making only one of the metal plates have the performance suitable for the application. Due to the different expansion coefficients, not only warping occurs during the heating and foaming process of foamed resin materials, but also
It was difficult to manufacture the product because it could not be cut to a predetermined size. The present invention was made in order to solve the above AG problem, and its purpose is to provide performance suitable for the intended use, suppress the increase in cost, and prevent warpage. It is an object of the present invention to provide a method for manufacturing a heat insulating panel in which the occurrence of less .

抑制されて実用上問題がないことが証明された。The present invention consists of a pair of metal plates 1.211r that are vertically opposed to each other.
Metal plate 1.2 is made by injecting foamed resin material into 1 and heating the 4tR plate 1.2 to foam the foamable resin material.
In a method for producing a heat insulating panel, in which a foamed resin M3 is filled in between to form a heat insulating board material 5, and this heat insulating board material 4 is cut into a predetermined size, the upper and lower metal plates 1.2 are made of different materials, and the upper and lower metal plates 1 and 2 are made of different materials. 1.2 is characterized by different heating temperatures, and this configuration solves the above problem. [Function 1] Since the materials of the upper and lower metal plates 1.2 are different, it is possible to manufacture a heat insulating panel A that has performance suitable for the application.Moreover, since the heating temperature of the upper and lower metal plates 1.2 is different, the upper and lower metal plates 1.2 can be made of different materials. The purpose is to compensate for the difference in m-expansion coefficients of the metal plates 1.2, and to reduce warping that occurs in the heat insulating panel A. The present invention will be explained below based on the accompanying drawings. Metal plates 1.2 include galvanized iron plates, aluminum plates, galvanized steel plates, aluminum-zinc alloy plated steel plates, stainless steel plates, titanium steel plates, etc., or these metal plates colored with general paints, PVC resin, acrylic, etc. Those coated with film, fluororesin, etc. are used. Among these, stainless steel plates are preferably used in food-related, wood-related, aseptic rooms, etc., and titanium steel plates are preferably used in areas where there is a risk of salt damage. As shown in Figure 3, the insulation panel A is a foaming material such as hard urethane 7ohm, incyanurate 7ohm, or phenol 7ohm, which contains polyol, isocyanate, catalyst, foaming agent, etc. between the metal plates 1.2. It is formed by injecting a resin material, foaming it, and filling it with a foamed resin layer 3. Next, the manufacturing method of the present invention will be explained with reference to the accompanying drawings. As shown in FIG. 1, metal hoops 5.6 forming the upper and lower metal plates 1.2 are each wound around a payoff 17-rule 7.8. The metal material 5.6 supplied from the payoff reel 7.8 is bent at both ends by forming rolls 9.10. Next, the metal 7-ply material 5.6 is placed in the preheating chamber 1.
1 is preheated to 20 to 50° C., and then a foamable resin material is injected between the metal hoop members 5 and 6 by the injection device 12. After this, the metal 7-ply material 5.6 is transferred to the double conveyor 13.
The foamable resin material foams as it is transported and moved, and the foamed resin layer 3 fills the metal 7-ply material 5.6 to form the heat insulating board material 4. The double conveyor 13 is heated by hot air ducts 17, 18 arranged above and below, the metal 7-ply material 5,6 is heated, and the foamable #IWt material is foamed. In this case, the metal 7-pipe material 5.6 is heated at 20 to 70°C.
Among the metal 7-ply materials 6.7, the one with the smaller #X expansion coefficient is heated to a high temperature. The coefficient of linear expansion is 1°3 for galvanized steel sheets and aluminum-zinc alloy plated steel sheets.
X 10-51/'C, stainless steel plate is 1.47
X10 ””ms/ ”C, aluminum plate is 2.31
X10-sIllI/℃, titanium steel plate is 0.86X
10-'mm/'C. The heating temperature difference of the metal 7-ply material 6.7 is set to 20°C or less. In this case, there is a limit to the temperature difference that can be set depending on the type of foamable resin material, and care must be taken because exceeding this limit may have an adverse effect on the foaming of the foamable resin material and cause a decrease in the physical properties of the panel. As shown in Fig. f52, side seal conveyors 14 are installed on both sides of the double conveyor 13, and a side sealing material 15 such as a film such as aluminum foil paper, aluminum foil, or plastic film, EPT, or a pack such as foamed neoprene rubber is used to seal the metal. 7- Both sides of the plastic material 5.6 are pressed to prevent the foamable resin material 3 from leaking. The heat insulating board material 4 formed in this way is slowly cooled and the metal 7-b material 5.6 shrinks, but since the heating temperature difference between the metal 7-b material 6.7 is provided, the heat insulating board material 4 The occurrence of warping is suppressed. Next, a cutting device 16 such as a band saw
In this way, the heat insulating material A is manufactured by cutting the heat insulating plate material 4 into a predetermined size. Detailed explanation of the invention to the dog. (Example 1) The linear expansion coefficient of the upper metal plate is 1.47X10-5II
A stainless steel plate of III/°C was used, and a color galvanized steel plate of #aB elongation of 1.3 x 100-5a/'C was used as the lower metal plate. Urethane 7 ohm was used as the foamable resin material. The heating temperature of the stainless steel plate was 28 to 30°C, and the heating temperature of the color galvanized steel plate was adjusted to TI4 of 36 to 38°C, and the temperature difference was set to 6 to 10°C. The line speed was 10+1/in and the residence time in the double conveyor was 3.6 minutes. The warpage of the heat insulating panel manufactured in this manner with a thickness of 35 mm was 10 to 15 m5+ at panel i5000 mI@. (Example 2) As the upper metal plate, m expansion coefficient is 2.31X10-5m
A heat insulating panel with a thickness of 45 mm was manufactured in the same manner as in Example 1 except that an aluminum plate of m/''C was used.
m- (Comparative example) Example 2 except that the heating temperature difference between the first and metal plates was not set.
A heat insulating panel with a thickness of 45 mm was manufactured in the same manner as above. The warpage of this insulation panel is 70~ for a panel of 17,300 mm.
It was 80em. In the examples of the present invention, warping was considerably suppressed compared to the comparative examples, and it was proved that there was no problem in practical use.

である。In the present invention, a foamable resin material is injected between a pair of vertically facing metal plates, the metal plates are heated, and the foamable resin material is foamed, thereby filling a foamed resin layer between the metal plates. In the manufacturing method of insulation panels, in which the upper and lower metal plates are made of different materials, it is possible to manufacture insulation panels with performance that suits the application, and the upper and lower metal plates are made of different materials. Since the heating temperatures are different, it is possible to compensate for the difference in linear expansion coefficient between the upper and lower metal plates.
This can reduce warping that occurs in manufactured insulation panels.
