真空断熱パネルが開発されている。Conventionally, rigid urethane foam has been widely used as a heat insulating material for electric refrigerators. However, a foaming agent is used to form the foam in the space which becomes the heat insulating wall surface. As chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCF)
C) etc. are used. However, recently, due to the danger of ozone layer depletion associated with the use of CFCs and the risk of temperature rise due to the theory of global warming, the use and production of CFCs has been severely restricted on a global level. Vacuum insulation panels have been developed as insulation materials to replace the rigid urethane foam.

ている。As one of the above vacuum heat insulating panels, as disclosed in Japanese Patent Laid-Open No. 58-50394 (a method for manufacturing a heat insulating plate), a breathable packaging bag is filled with powder, and this is used as a surface. It is known that it is put in an outer bag consisting of a backing material and sealed and sealed in a vacuum state.Since such a vacuum heat insulation panel has a panel shape, a hard urethane that forms a foam layer in the heat insulation wall space. Unlike foam, it is necessary to mount and fix the vacuum heat insulating panel on the wall surface of an electric refrigerator or the like, and as a mounting method, a bonding method using a hot melt adhesive between both members is generally adopted.

Since the hot-melt adhesive solidifies and adheres in just a few seconds, when the vacuum heat-insulating panel is once fixed with the hot-melt adhesive and is fixed outside the predetermined fixing position, the vacuum heat-insulating panel is fixed. If it is impossible to correct to a correct fixed position, and even if it is attempted to correct to a correct fixed position in this state, the vacuum heat insulating panel may be damaged due to excessive force applied to the vacuum heat insulating panel.

効である。Further, in the above example, since the magnetic layer 6 made of a ferromagnetic metal such as iron foil is formed over the entire surface of the sealing bag 4, the layer 6 provides a gas barrier property and the layer 6 serves as the gas barrier metal layer 10. Is not communicated with and is not directly heat-conducted, so that even if this magnetic layer 6 receives heat from the peripheral portion of the panel, it reflects the heat and the movement of the opposite surface of this heat is prevented. In addition, since the gas barrier metal layer 10 has the same function and effect, the vacuum heat insulating panel 1 prevents gas permeation into the sealing bag 4 as much as possible, and the degree of vacuum in the sealing bag 4 is long. It is maintained over a long period of time, and as described above, there is little movement of the heat-opposite surface from the peripheral portion of the panel, which provides good heat insulation. The magnetic layer 6 and the gas barrier metal layer 10 are described above.
In terms of the effect of preventing heat conduction to the opposite surface, it is also effective to form one or both of the layers 6 and 10 on the entire surface of the sheets 2 and 3 excluding the heat-bonded portion. is there.

ガスバリア層を形成することが好適である。As another aspect of the present invention, instead of forming the magnetic layer 6, the magnets 14, 14 are fixed to the surface protective layer 8 with an adhesive to fix the panel 1 to the panel 1. It can be easily and positionally fixed to the heat insulating wall 13. In this case, it is preferable to replace the magnetic layer 6 with a non-magnetic metal such as an aluminum foil or an aluminum vapor deposition film to form the gas barrier layer.
