いう欠点があつた。 In general, fresh foods such as meat, fish, and vegetables are stored by cooling them to maintain their freshness.Insulating sheets are placed on product cases or wrapped around insulating curtains placed over openings such as windows. Conventionally, this kind of heat-retaining sheet used a sheet made of polyethylene, etc., so heat rays from the high-temperature side penetrated through the sheet and warmed the low-temperature side, making it difficult to obtain a sufficient heat-retaining effect. There was a drawback that I couldn't do it. Therefore, it is known that metal such as aluminum is deposited on a resin sheet to reflect heat rays from the high temperature side, and a foamed resin layer and a reinforcing material layer are added. Thin metals with good thermal conductivity such as aluminum were laminated by simple bonding, which required a large number of steps.Especially when using rigid materials such as metal lath as reinforcing materials, each layer The disadvantage was that it could not absorb the difference in expansion and contraction between the materials.

Of course, the purpose is to provide a heat-retaining sheet structure with excellent flexibility and laminated structure.

されている。 The structure of the present invention will be explained based on an embodiment shown in the drawings. Reference numeral 1 denotes a heat-retaining sheet, and the heat-retaining sheet 1 includes a metallic reflective layer 2 serving as the surface facing the outside air, and a metallic reflective layer 2 serving as the surface facing the outside air. It has a three-layer structure including a foamed resin layer 3 and a woven fabric layer 4 which is an example of a reinforcing material layer on the cold air side. In this embodiment, the metallic reflective layer 2 is composed of an aluminum vapor-deposited film in which aluminum 2b is vapor-deposited on a polyester film 2a, and the metallic reflective surface made of aluminum is protected by the polyester film 2a. The metal is not limited to aluminum, and of course, commonly known metals such as tin and zinc can be used, and the metallic reflective layer 2 may be a resin film such as a polyester film on which a metal is vapor-deposited. The metal layer also has the advantage of being thin and uniform, but it is not limited to this, and any material that can reflect heat rays with a shiny metallic surface may be sufficient. Next, although the foamed resin layer 3 is made of foamed polyethylene resin with a high closed cell ratio in this embodiment, it is also possible to use a commonly known foamed resin such as a flexible polyurethane resin. In this case, a material with a higher closed cell ratio is preferable because it has better heat insulation performance, but even if it is made of a soft polyurethane resin with a low closed cell ratio, the foamed resin layer 3 can be formed by forming the metallic reflective layer 2 and the woven fabric layer. Since it is located in the middle of a so-called Sanderutsch structure sandwiched between 4 and 4, there is no deterioration in insulation performance. On the other hand, the woven fabric layer 4 is woven by plain weaving polyethylene threads obtained by stretching polyethylene resin into a film shape as weft and warp threads, but it goes without saying that the material of the threads, the weaving method, etc. can be selected as appropriate. However, any reinforcing material in the form of cloth such as non-woven fabric or woven net may be used as long as it can ensure the strength required for the heat-retaining sheet 1. The main materials of the metallic reflective layer 2, foamed resin layer 3, and woven fabric layer 4 constructed in this way are integrated by laminating a polyethylene laminate layer 5 on the low-temperature side of each of the above layers by heat processing. has been made into

た。 Next, a case will be described in which the heat retention effect was tested using the cold insulation sheet 1 of the present invention constructed as described above. In this test, the thermal sheet 1 of the present invention was made of a 12 micron polyester film.
Comparison with the present invention was made using a sample (sample 1) consisting of a metallic reflective layer with a 500 angstrom aluminum vapor deposited layer, a 1 mm thick polyethylene foam resin layer, and a woven polyethylene fabric layer. In order to do this, a sheet was prepared by laminating a 12 micron polyester film on the polyethylene woven fabric used in Sample 1 (sample 2) in the same manner as in the embodiment of the present invention, and a metallic sheet in which approximately 500 angstroms of aluminum was vapor-deposited on a 12 micron polyester film (sample 2). A sheet (sample 3) obtained by laminating the polyethylene woven fabric used in sample 1 was used as the reflective layer.

に優れていることがわかる。 The results of this comparison are shown in the graph of Figure 2. The thermal insulation sheet of the present invention can be used not only for blank sheets on which dry ice is left, but also for samples 2 and 3.
It is clear that Sample 1, which is an example of the present invention, has a superior heat retention effect compared to that of Sample 3, which is considered to have an excellent heat retention effect. For example, it is a noteworthy effect that there was a difference of about 30 minutes at a survival rate of 50%. Furthermore, in this test, no dew condensation phenomenon was observed in the thermal insulation sheet of the present invention, but dew condensation phenomenon was observed in both Samples 2 and 3. It can be seen that the properties are very good.

は凹凸面の形成を説明する図面である。 The present invention is of course not limited to the above test example, but the heat retaining sheet 1 is formed by integrally molding a metallic reflective layer 2, a foamed resin layer 3, and a woven fabric layer 4 by laminating. Because of this, the woven fabric layer 4 thermally expands more than the metallic reflective layer 2 due to heating during lamination, and as a result, the metallic reflective layer 2, which was flat before laminating, expands into countless layers. A striped uneven surface is formed, and the uneven surface diffusely reflects the light rays from the electric light from the outside air side, which has the advantage of effectively preventing dazzling by the reflected light from the metallic reflective layer 2. be. FIG. 2 is a diagram illustrating the formation of an uneven surface.

大きな効果がある。 In summary, the present invention uses a heat-retaining sheet that separates and closes off the low-temperature side and the high-temperature side, with a foamed resin layer interposed between the reinforcing material layer on the low-temperature side and the metallic reflective layer on the high-temperature side. A polyethylene laminate layer was provided on the low-temperature side and laminated by heat processing to form a six-layer structure, so the metallic reflective layer was able to reflect heat rays from the outside air.
Because it has a sandwich structure with a foamed resin layer interposed in the middle, the metallic reflective layer with good thermal conductivity prevents temperature differences from acting directly due to the excellent insulation effect of the foamed resin layer. It can be highly effective, and if this heat insulation sheet is applied to product cases or openings such as windows,
Not only does it have an excellent heat-retaining effect, but the laminate layer maintains its thickness, is flexible, and has high utilization efficiency, making it a great contribution to energy conservation. Additionally, since the layer is laminated by heating, the metallic reflective layer has numerous uneven surfaces, which is highly effective in preventing glare during daily use.
