- the core material has a first surface facing the first inner surface and a second surface facing the second inner surface, The first inner surface and the first surface are adhered, and the second inner surface and the second surface are adhered.
- FIG. 1 It is a block diagram which shows an example of the vacuum insulation panel which concerns on 1st Embodiment of this invention, (a) shows a perspective view, (b) shows sectional drawing, (c) is a partial enlargement of (b).
- FIG. 1 is a configuration diagram showing an example of a vacuum insulation panel according to a first embodiment of the present invention, where (a) shows a perspective view, (b) shows a cross-sectional view, and (c) shows (b). shows a partially enlarged view of.
- the vacuum insulation panel 1 shown in FIGS. 1(a) to 1(c) comprises a hollow body 10 and a core material 20 housed inside the hollow body 10. As shown in FIG.
- the hollow body 10 is formed by processing a plurality of (two) metal plates 11 and 12 to form a hollow portion H inside.
- Each of the metal plates 11 and 12 has heat resistance to withstand a flame of at least 781° C. for 20 minutes or more, that is, does not melt against a flame of at least 781° C. for 20 minutes or longer.
- Each of the metal plates 11 and 12 preferably has heat resistance to withstand a flame of 843° C. for 30 minutes, more preferably heat resistance to withstand a flame of 902° C. for 45 minutes (heat resistance without dissolution).
- Each of the metal plates 11 and 12 is made of stainless steel, for example.
- Each metal plate 11, 12 is processed so as to have a recess.
- the hollow body 10 is assembled so that the recesses of the metal plates 11 and 12 are aligned with each other, and the portions other than the recesses, excluding a communication port 40, which will be described later, are integrated via the joint portion 13.
- a hollow portion H is formed by being formed.
- the hollow portion H is formed by sealing the outer peripheries of the metal plates 11 and 12 via the joint portion 13 .
- the surfaces of the metal plates 11 and 12 facing the hollow portion H are examples of a first inner surface and a second inner surface facing each other with the hollow portion H therebetween.
- the joint 13 is formed by seam welding or diffusion bonding.
- the core material 20 is a solidified foam having open cells.
- the core material 20 is made of, for example, an inorganic material, and has a thickness of, for example, several centimeters or more in this embodiment.
- the core material 20 has heat resistance to withstand a flame of at least 781° C. for 20 minutes or more, that is, it does not burn and shrink against a flame of at least 781° C. for 20 minutes or more. It does not generate outgassing.
- the core material 20 is made of at least one of, for example, foam glass, perlite powder, vermiculite, fumed silica, diatomaceous earth, and calcium silicate. It is preferable that the core material 20 is spread all over the inside of the hollow portion H.
- the core material 20 is preferably one that does not decompose and deteriorate for 50 years and does not generate outgassing. Further, the core material 20 has a specific gravity of 0.7 or less, preferably 0.5 or less, and more preferably 0.2 or less due to weight restrictions for construction.
- the hollow portion H of the vacuum insulation panel 1 according to the first embodiment is evacuated.
- the core material 20 in the hollow portion H forms open cells, the inside of the open cells is evacuated by vacuuming to exhibit heat insulating properties.
- the conventional vacuum insulation panel did not satisfy the wind pressure resistance required as a building material.
- the panel is a sandwich panel composed of a core material that does not bear the strength and stainless steel face plates on the indoor side and the outdoor side that bear the strength.
- Such a section modulus requires a thickness of 7.7 mm to be realized with a single stainless steel plate, and a thickness of 5.5 mm is required for each of two stainless steel plates that are not adhered to each other. Not practical.
- a vacuum insulation panel using a resin film as a surface material requires a thickness several times greater than that due to the difference in fatigue limit, which cannot be achieved in practice.
- the vacuum insulation panel 1 has an adhesive layer 30 as shown in FIGS. 1(b) and 1(c).
- the vacuum insulation panel 1 includes a first inner surface 11a and a second inner surface 12a, which are inner surfaces of the hollow body 10 on one side and the other side of the panel, and a first surface 22a of the core material 20 on the one side of the panel. and the second surface 22b on the other side of the panel are adhered via an adhesive layer 30, respectively.
- the first inner surface 11a is the surface of the metal plate 11 facing the hollow portion H
- the second inner surface 12a is the surface of the metal plate 12 facing the hollow portion H.
- the first surface 22a is the portion of the surface portion 22 of the core material 20 that faces the first inner surface 11a, and the second surface 22b of the surface portion 22 of the core material 20 faces the second inner surface 12a. part.
- the entire inner surface of the hollow body 10, that is, the first inner surface 11a and the second inner surface 12a, and the entire surface portion 22 of the core material 20, that is, the first surface 22a and the second surface 22b is adhered only through the adhesive layer 30.
- the adhesive layer 30 is formed by applying an adhesive or the like. By providing the adhesive layer 30 in this way, the metal plates 11 and 12 and the core material 20 are integrated, and the wind pressure resistance performance is equivalent to that of a single thick plate material.
- the one side of the panel and the other side of the panel may be simply referred to as the one side and the other side (see FIGS. 1(a) and 1(b)).
- the vacuum insulation panel 1 has a width of 2 m, a height of 1 m, and a thickness of 50 mm. It is assumed that the plates 11 and 12 and the core material 20 are strongly bonded and integrated.
- the surface material of such a sandwich panel preferably has a fatigue limit of 50 N/mm 2 or more, more preferably about 100 N/mm 2 like the above stainless steel.
- the entire panel surface side of the core material 20 is adhered to the inner surface of the panel surface side of the hollow body 10. , more preferably 80% or more, and still more preferably 90% or more, are adhered. The same applies to the other side.
- water glass as the adhesive. Adopting water glass allows the core material 20 to be as light as possible so that the thermal conductivity of the core material 20 is low, and at the same time, a sufficient amount of adhesive is applied only to the contact portion between the inner surface of the hollow body 10 and the core material 20. This is because the adhesive can be strongly adhered to the substrate.
- the core material 20 according to the present embodiment has a density higher in the surface portion 22 than in the central portion 21 .
