[0002] For thermal insulation, insulating material is provided around air conditioning ducts and the like, and then exterior materials are provided around the insulating material. Conventionally, Galvalume steel sheets (registered trademark) have been used as such exterior materials. The use of Galvalume steel sheets as exterior materials for air conditioning ducts is described, for example, in Patent Document 1 (JP 2021-186226 A). [Patent Document 1] Patent Publication No. 2021-186226 Summary of the Invention [Problem to be solved by the invention]

[0003] Galvanized steel sheets are a relatively hard material, and wrapping them around insulation requires skilled craftsmanship, such as proper cutting and wrapping, and takes a considerable amount of time. In recent years, it has become difficult to secure skilled craftsmen, and a method has been sought that allows even inexperienced craftsmen to easily install exterior materials for air conditioning ducts, but such a method has not been proposed until now, which has been a problem. [Means for solving the problem]

[0005] Furthermore, the tape for fixing exterior materials according to the present invention is a tape for fixing exterior materials that fixes exterior materials arranged around insulation attached to an air-conditioning duct, and is characterized in that it includes a first metal layer, an intermediate layer provided on the first metal layer, a second metal layer provided on the intermediate layer, and a protective layer provided on the second metal layer, and that the intermediate layer and the protective layer are primarily composed of acrylic resin.

[0006] In addition, the insulating material with an exterior material attached according to the present invention is an insulating material with an exterior material attached that is attached to an air conditioning duct, and includes an insulating material, a base layer made of synthetic resin provided on the insulating material, a metal layer provided on the base layer, and a protective layer provided on the metal layer, and is characterized in that the protective layer is mainly composed of an acrylic resin. [Effects of the Invention]

[0007] The exterior packaging material of the present invention is based on a substrate layer made of synthetic resin, and is relatively flexible and easy to cut, making it easy to attach around the insulation material of an air conditioning duct. In addition, the outermost layer of the exterior packaging material of the present invention is formed from a protective layer mainly composed of acrylic resin, which also has an excellent aesthetic appearance.

[0008] Furthermore, with the tape for fixing an exterior material according to the present invention, the above-mentioned fixing of the exterior material can be easily carried out.

[0009] Furthermore, by manufacturing the heat insulating material to which the exterior material according to the present invention is attached in advance in a factory or the like, the construction time at the site can be reduced. [Brief explanation of the drawings]

[0011] The present invention will be described in detail below. Fig. 1 is a diagram showing an example of installation using an exterior material 10 according to an embodiment of the present invention. By providing a heat insulating material 5 around an air conditioning duct 1 or the like, heat exchange between the gas flowing through the air conditioning duct 1 and the air outside the air conditioning duct 1 is suppressed as much as possible. By further attaching an exterior material 10 to the outer periphery of this heat insulating material 5, deterioration of the heat insulating material 5 over time can be suppressed and the aesthetic appearance can be maintained.

[0012] The insulation material 5 placed around the air conditioning duct 1 has excellent insulation and heat resistance, but is not resistant to impact or ultraviolet rays. By installing the exterior material 10, it is possible to prevent the insulation material 5 from deteriorating or falling off. Furthermore, the exterior material 10 further enhances the heat and cold insulation effect of the insulation material 5, which is expected to reduce costs by preventing energy loss. The exterior material 10 also helps prevent condensation and freezing in the air conditioning duct 1. Since many air conditioning ducts 1 are installed in places where they are visible to people, the exterior material 10 ensures the above-mentioned performance and contributes to the exterior of the air conditioning duct 1 being clean and less susceptible to rust and deterioration.

[0013] The heat insulating material 5 may be, for example, a foam heat insulating material. Such a foam heat insulating material may be polystyrene foam, polyolefin foam, polyurethane foam, phenol foam, or polyvinyl chloride foam. The polyolefin foam may be, for example, polyethylene foam or polypropylene foam. Glass wool, rock wool, or the like may also be used as the heat insulating material.

[0014] The exterior packaging material 10 has a laminated structure of synthetic resin material films, thin metal materials, etc. The exterior packaging material 10 according to the present invention is based on a substrate layer made of synthetic resin, and is relatively flexible and easy to cut out, making it easy to attach to the periphery of the heat insulating material of the air-conditioning duct 1.

[0015] FIG. 2 is a schematic diagram showing the cross-sectional structure of an exterior packaging material 10 according to an embodiment of the present invention. Examples of resin films that can be used as the base layer 11 include films made from aromatic polyester-based resins such as polyethylene terephthalate (PET) resin and polybutylene terephthalate (PBT) resin; polyolefin-based resins such as polyethylene resin, polypropylene resin, and olefin copolymer; vinyl chloride-based resins such as polyvinyl chloride resin and vinyl chloride copolymer; polyamide resins such as nylon 6, nylon 66, and metaxylylenediamine-adipic acid condensate; styrene-based resins such as polyvinyl alcohol resin, acrylonitrile-butadiene-styrene copolymer, and acrylonitrile-styrene copolymer; thermoplastic resins such as polymethyl methacrylate resin, acrylic resins such as acrylic ester resin and methyl methacrylate ester copolymer, ethylene-vinyl alcohol copolymer, polyvinyl alcohol resin, and partially saponified versions thereof; and thermosetting resins such as phenolic resin and urea resin. In this embodiment, polyvinyl chloride resin is used, which is advantageous in terms of cost.

[0016] The metal layer 12 can be obtained by attaching a metal foil to the base layer 11 or by vapor-depositing a metal or the like onto the base layer 11. Examples of metal materials that can be used for the metal layer 12 include aluminum, copper, stainless steel, and iron, with aluminum being preferred. Further, the metal layer 12 can be formed by vapor-depositing a metal such as aluminum, stainless steel, cobalt, or nickel, or silica, alumina, or a combination thereof, using a vapor deposition method, sputtering method, or the like.

[0017] The protective layer 15, which is the outermost layer of the exterior packaging material 10 according to the present invention, is a resin film primarily composed of an acrylic resin such as an acrylic ester resin and a methyl methacrylate ester copolymer. Here, the term "main component" refers to the component that occupies the largest amount in the composition, and this also applies hereinafter unless otherwise specified. Because the protective layer 15, which is the outermost layer of the exterior packaging material 10 according to the present invention, is made of a material primarily composed of an acrylic resin, which has excellent transparency, the metal layer 12 can be clearly seen through the protective layer 15, and the exterior packaging material 10 according to the present invention has an excellent aesthetic appearance. The protective layer 15 may also contain an additive that imparts weather resistance to the protective layer 15. In this embodiment, Sunduren 001 manufactured by Kaneka Corporation was used as the protective layer 15.

[0018] The adhesive for forming the adhesive layer 21 is not particularly limited as long as it can be applied at room temperature, and examples thereof include acrylic adhesives, rubber adhesives, urethane adhesives, silicone adhesives, polyvinyl ether adhesives, olefin adhesives, etc. These adhesives may be used alone or in combination of two or more.

[0019] A release sheet 22 is attached to the adhesive layer 21. A film or paper coated with a lubricating release agent can be used as the release sheet 22. The release agent can be a silicone-based release agent, a fluorine-based release agent, or the like.

[0020] The exterior packaging material 10 according to the present invention configured as described above is based on a substrate layer 11 made of synthetic resin, and is relatively flexible and easy to cut out, making it easy to attach around the insulation material 5 of the air-conditioning duct 1. In addition, the outermost layer of the exterior packaging material 10 according to the present invention is formed of a protective layer 15 mainly composed of an acrylic resin, which allows the metal layer 12 to be seen through, and is also aesthetically pleasing.

[0021] Next, another embodiment of the present invention will be described. Fig. 3 is a diagram schematically showing the cross-sectional structure of an exterior material 10 according to another embodiment of the present invention. In the other embodiment shown in Fig. 3, components denoted by the same reference numerals as those in the previous embodiment are the same as those in the previous embodiment, and therefore description thereof will be omitted. In the exterior material 10 according to the present invention, the adhesive layer 21 and the release sheet 22 are not necessarily essential components, and for example, the exterior material 10 according to the present invention may have the cross-sectional structure shown in Fig. 3. Next, another embodiment of the present invention will be described. The tape 30 for fixing an exterior material is used to fix an exterior material 10 attached around the heat insulating material 5 of an air-conditioning duct 1. Fig. 4 is a diagram showing a schematic cross-sectional structure of the tape 30 for fixing an exterior material according to an embodiment of the present invention. In Fig. 4, components with the same reference numbers as those in the previous embodiment are the same as those in the previous embodiment, and therefore their description may be omitted.

[0022] In the tape 30 for fixing an exterior material according to the present invention, an adhesive layer 21 is provided on a release sheet 22, and a first metal layer 12 is further provided on the adhesive layer 21. The metal material described above can be used for the first metal layer 12. An intermediate layer 14 is provided on the first metal layer 12. A resin film containing an acrylic resin, such as an acrylic ester resin and a methyl methacrylate ester copolymer, as its main component is used for this intermediate layer 14. A second metal layer 12 is provided on the intermediate layer 14. The metal material that can be used for the second metal layer 12 can also be the same as that described above. A protective layer 15 is provided on the second metal layer 12. A resin film containing an acrylic resin, such as an acrylic ester resin and a methyl methacrylate ester copolymer, as its main component is also used for this protective layer 15.

[0023] By using the tape 30 for fixing an exterior material according to the present invention from which the release sheet 22 has been peeled off, the fixing of the exterior material 10 can be easily carried out. Furthermore, the tape 30 for fixing an exterior material according to the present invention has a similar layered structure to that of the exterior material 10, as described above, and there is no sense of incongruity when the exterior material 10 is fixed with the tape 30 for fixing an exterior material. Furthermore, in this embodiment, the tape 30 has a four-layer layered structure of the first metal layer 12, the intermediate layer 14, the second metal layer 12, and the protective layer 15, so that the stiffness and strength of the tape 30 for fixing an exterior material can be ensured.

[0024] Next, another embodiment of the present invention will be described. FIG. 5 is a diagram schematically illustrating the cross-sectional structure of a tape 30 for fixing an exterior material according to another embodiment of the present invention. In the other embodiment shown in FIG. 5, components denoted by the same reference numerals as those in the previous embodiment are the same as those in the previous embodiment, and therefore will not be described again. In the previous embodiment, a laminated structure was provided in which a first metal layer 12 was disposed on an adhesive layer 21, an intermediate layer 14 was disposed on the first metal layer 12, a second metal layer 12 was disposed on the intermediate layer 14, and a protective layer 15 was disposed on the second metal layer 12. However, in the embodiment shown in FIG. 4, the first metal layer 12 and the intermediate layer 14 can be omitted. According to this embodiment, the strength of the tape 30 for fixing an exterior material may be weaker than that of the previous embodiment, but it is advantageous in terms of cost.

[0025] Next, another embodiment of the present invention will be described. FIG. 6 is a diagram showing the manufacturing process for a thermal insulation material 40 to which a packaging material 10 is attached. The diagram shows how half of the packaging material 10 is attached to a halved piece of thermal insulation material 5. This manufacturing process can use a process in which the packaging material 10 is integrated with the thermal insulation material 5 by vacuum forming. In vacuum forming, a pressure difference is used to apply force in the direction of the arrow in the figure to attach the packaging material 10. In vacuum forming, the packaging material 10 can also be one that does not include the adhesive layer 21 and the release sheet 22. In this case, the packaging material 10 that can attach the base material layer 11 to the thermal insulation material 5 by thermal welding can be the same as those described above. By manufacturing the thermal insulation material 40 to which the packaging material 10 according to the present invention is attached in advance in a factory or the like, on-site construction time can be reduced.
