Conventional heat insulating materials, as described in Japanese Patent Publication No. 59-48917, are bright surface films made by depositing metals such as aluminum on one or both sides of a plastic film with a thickness of about 25 μm and embossing on one or both sides. Spacers made of nets woven from plastic fibers such as polyester and having a mesh size of about 20 meshes with a thickness of about 200 μm were alternately laminated. However, no consideration was given to the fact that the actual area of the embossed bright film surface increases compared to the projected area, resulting in an increase in heat penetration due to radiant heat transfer.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6. FIG. 2 shows a bright surface film 10 made of a plastic film made of a polymeric material, for example, a polyimide film having a thickness of about 25 μm, and aluminum having a thickness of about 800 Å deposited on both sides of the film.
Fig. 3 shows a plastic film which is a polymeric material, for example, a polyimide film with a thickness of about 25 μm, which has been textured on one or both sides, with depressions 22 and protrusions 21 formed at equal pitches in the vertical and horizontal directions. This is the spacer 20. The laminated heat insulating material is constructed by alternately laminating bright surface films 10 and spacers 20. Figure 1 shows the cross-sectional structure of the laminated insulation material. Since the bright surface film 10 has a smooth surface, the projected area So in the stacking direction and the actual area Sa are equal, and if the emissivity of the deposited aluminum is ξ, then the amount of heat transferred by radiation Q is Qr=Saξ(T 4 1 −T 4 2 ). Here, T 1 is the temperature of the high-temperature heat-radiating surface, and T 2 is the temperature of the low-temperature heat-receiving surface. ξ is approximately 0.02 to 0.04 on the aluminum vapor deposited surface. In other words, in the conventional bright surface film 10 which is textured, the substantial area Sa becomes larger and the amount of heat transfer Qr becomes larger.

値である。 The amount of heat transferred through the spacer 20 sandwiched between the two bright films 10 at different temperatures T 1 and T 2 is the thermal conductivity of the polyimide film k, and the amount of heat transferred to the upper and lower bright films 10 is If the in-plane path length of the unevenness is L and the plate thickness is t, it can be expressed as Qc=t/Lk(T 1 −T 2 ) per unit length. Here, unless the spacer material is changed, t may be made smaller and L may be made larger.
However, if t is made too small, the rigidity of the textured film will decrease, making it difficult to maintain the shape, and the uneven shape will be crushed by the winding pressure during laminated material construction, resulting in an increase in Qc. Therefore, if a polyimide film with a thickness of about 25 μm is used and roughened, L can be maintained at about 1 to 2 mm. Comparing the insulation performance of the laminated insulation material made of the bright surface film 10 and the spacer 20 in this case with that of the conventional laminated insulation material made of a combination of the uneven bright surface film and the net-shaped spacer, it is found that the bright surface film The emissivity of both is the same because aluminum is vapor-deposited. However, the actual area of the bright surface film of this embodiment is about 40% smaller than that of the conventional uneven bright surface film. Also, the value of t/L is 25/1000 for the spacer 20 in this case, while
In a conventional net-shaped spacer with a wire diameter of 70 .mu.m and a net aperture ratio of 85%, the ratio is (70/200).(1-0.85), and t/L in this case is halved compared to the conventional one. Here, the insulation performance of the laminated heat insulating material wrapped around the side of a cylindrical liquid nitrogen container with an outer diameter of 40 mm and a temperature of 77K is calculated per unit area of the container from the heat dissipation surface with a temperature of 300㎓ in the vacuum space to the liquid nitrogen container. amount of heat q
Figure 4 shows a comparison of the number of layers of bright film in the laminated heat insulating material. Curve a in FIG. 4 is the value in this case, and curve b is the value for the conventional laminated insulation material.

報の積層断熱材に比べ、約50％向上できる。 In this case, an aluminum evaporated film is provided on one or both surfaces of the spacer 30, which has uneven undulations on both sides of the polyimide film, or in this case, on both sides. The aluminum evaporated film is made discontinuous in between.
The bright surface film 10 is in contact with the top and bottom of the spacer 30, that is, the convex top and concave bottom of the undulations.
The aluminum vapor deposited film is broken between the convex top and the concave bottom of the undulations, that is, it forms a non-deposited part and is discontinuous, so heat flows inside the aluminum vapor deposited film between the concave bottom and the convex top. It will never be conveyed.
That is, the amount of heat transferred through the spacer 30
Regarding Qc, the thermal conductivity k is almost the same as that of the spacer 20 of the above embodiment, but the emissivity of the pair of the spacer 30 and the bright surface film 10 is as follows:
The emissivity of the pair of the spacer 20 made only of polyinide film and the bright surface film 10 of the above embodiment is approximately
Compared to 0.9, it is smaller at 0.40. Therefore, as shown in FIG. 6, a cylindrical low temperature container 5 as an inner container
At the location C where the end face of the heat insulating material 40 wrapped around 0 is exposed to the vacuum space, the inner layer of the heat insulating material directly receives radiant heat from the atmospheric temperature. It can be reduced to about 1/12 compared to a heat insulating material using uneven spacers 20 without a membrane. In addition, since the spacer can be made uneven to increase the distance between the bright surface films, the amount of radiation heat transfer between the bright surface films can be reduced, and the amount of conductive heat transfer within the spacer can also be reduced. The insulation performance of the insulation material can be improved by approximately 50% compared to the conventional laminated insulation material disclosed in Japanese Patent Publication No. 59-48917.

に比べ約20％向上する。 Next, a second embodiment of the present invention will be described with reference to FIG. The difference from the above embodiment is that spacers 20 without aluminum deposition are used for the inner layer of the laminated insulation material, that is, the two layer spacers on the low-temperature container 50 side, and the outer layer of the laminated insulation material, that is, the spacer 20 is exposed to the vacuum space. For the two layers on the high temperature side, spacers 30 made of discontinuous aluminum vapor deposition were used. This means that in the laminated insulation except for the construction edges, that is, in the area where heat transfer occurs in the lamination direction, radial heat transfer is dominant in the outer layer of the insulation, and in the inner layer,
Conduction heat transfer becomes dominant. Therefore, the heat insulation performance of the laminated heat insulating material of the second embodiment, which combines the bright surface film 10 and the spacer 30 in which aluminum is discontinuously deposited on the outer layer where radiation heat transfer is dominant, is as follows. The insulation performance is improved by approximately 20% compared to the laminated insulation material using the uneven spacer 20 without a vapor deposited film.

The effect is that the amount of heat transfer due to heat and conductive heat transfer can be reduced, and good heat insulation performance can be obtained.
