Description
本発明は、建物や構造物に設置する遮熱断熱シートの構造に関するものである。 TECHNICAL FIELD The present invention relates to the structure of a heat-shielding and heat-insulating sheet installed in a building or structure.
建物や構造物に遮熱断熱シートを設置して、遮熱断熱効果を高め、環境の改善、エネルギーの節約を図ることは広く実施されている。高い断熱効果を得るために、断熱材の厚さを増やすことは安易であるが、構造上採用できないケースがほとんどである。断熱材だけでなく、金属箔の遮熱シートを組み合わせた遮熱断熱シートは既に特許文献１に開示されている。しかし、この遮熱断熱シートは多孔性の断熱材を金属箔で挟んで接着したもので、温和な条件では期待される遮熱断熱の効果が得られるが、低温、高温の悪条件では期待される効果が得られないといった問題があった。 2. Description of the Related Art It is widely practiced to install a heat-shielding and insulating sheet in a building or structure to improve the heat-shielding and insulating effect, improve the environment, and save energy. It is easy to increase the thickness of the heat insulating material in order to obtain a high heat insulating effect, but in most cases it cannot be adopted due to structural considerations.
低温、高温又は照射熱にさらされる悪条件下でも、効果的な遮熱断熱効果が得られる遮熱断熱シートを提供する。 To provide a heat-shielding and insulating sheet capable of obtaining effective heat-shielding and heat-insulating effect even under adverse conditions of exposure to low temperature, high temperature, or radiant heat.
本発明は、金属箔と多孔性断熱材の組合せからなる遮熱断熱シートであって、該遮熱断熱シートの表裏の少なくとも１面は金属箔で構成され、該金属箔の１面に多孔性断熱材－金属箔－多孔性断熱材からなるサンドイッチ構造の構成材のユニットを単数又は少なくとも２ユニットを接着する構造を特徴とする遮熱断熱シート。 The present invention relates to a heat shielding and insulating sheet comprising a combination of a metal foil and a porous heat insulating material, wherein at least one of the front and back surfaces of the heat shielding and heat insulating sheet is made of a metal foil, and one surface of the metal foil is porous. 1. A heat shielding and insulating sheet characterized by a structure in which one or at least two units of constituent members of a sandwich structure consisting of a heat insulating material, a metal foil, and a porous heat insulating material are bonded together.
本発明の遮熱断熱シートは、低温、高温又は照射熱にさらされる悪条件下でも、効果的な遮熱断熱効果が得られる遮熱断熱シートである。 The heat-shielding and insulating sheet of the present invention is a heat-shielding and insulating sheet capable of obtaining an effective heat-shielding and heat-insulating effect even under adverse conditions such as exposure to low temperature, high temperature, or radiant heat.
金属製の箔の表裏に断熱効果がある断熱材を接着して、金属箔を断熱材で挟む所謂サンドイッチ構造のユニット（断熱材－金属箔－断熱材のユニット）を調製する。金属製の箔の材質は特に限定されないが、放射率が低いため外部からの熱を内部の断熱材側へ輻射熱としての移動を遮断する効果が高くなる高純度アルミ箔シートが好適に用いられる。断熱材の材質は特に限定されないが、４角形網目構造や６角形のハニカム構造の発泡性ポリエチレンシート、発泡ポリスチロール、発泡ポリウレタン、発泡ポリ塩化ビニル、発泡ポリフェノール等が用いられる。
中でも、遮熱効果が高く、曲げ加工等に適している、４角形網目構造を有する柔軟な素材の発泡ポリエチレンシートが好適に用いられる。
調製したユニットの表裏の面に、ここで用いる金属製の箔は
アルミ製の箔シートの表面に防護塗装を施したものが好適に用いられる。A unit having a so-called sandwich structure (insulating material-metal foil-insulating material unit) is prepared by bonding a heat insulating material having a heat insulating effect to the front and back of a metal foil and sandwiching the metal foil between the heat insulating materials. The material of the metal foil is not particularly limited, but a high-purity aluminum foil sheet is preferably used because it has a low emissivity and has a high effect of blocking the transfer of heat from the outside to the heat insulating material inside as radiant heat. Although the material of the heat insulating material is not particularly limited, foamed polyethylene sheets having a square network structure or hexagonal honeycomb structure, foamed polystyrene, foamed polyurethane, foamed polyvinyl chloride, foamed polyphenol, and the like are used.
Among them, a foamed polyethylene sheet, which is a flexible material having a quadrangular network structure and which has a high heat shielding effect and is suitable for bending, is preferably used.
The metal foil used here is preferably an aluminum foil sheet with protective coating applied to the front and back surfaces of the prepared unit.
上述の断熱材－金属箔－断熱材のユニットの片面にさらに高純度アルミ箔シートを接着し、さらに断熱材を接着する複層ユニットを調製し、その表裏に金属製の箔を接着して、金属箔－（ユニット）×２－金属箔からなる遮熱断熱シートとしても良い。さらにユニットの数を適宜増やしても良い。 A high-purity aluminum foil sheet is further adhered to one side of the above-mentioned heat insulating material-metal foil-insulating material unit, and a multilayer unit is prepared by further bonding heat insulating material, and metal foil is adhered to the front and back of the unit, It is also possible to use a heat-shielding and insulating sheet consisting of metal foil-(unit)×2-metal foil. Furthermore, the number of units may be increased as appropriate.
厚さ１０ｍｍ、幅３００ｍｍのポリエチレンフォームに長さ６０ｍｍ、間隙５ｍｍで切り込みを入れて、幅１０００ｍｍになるように広げた。その片面に、高純度アルミ箔シートを貼り付け、次いで高純度アルミ箔シートの表面に前記のポリエチレンシートを接着して、断熱材－金属箔－断熱材のユニットを調製した。そのユニットの表裏に保護塗装したアルミ箔をそれぞれ接着し、単層ユニットからなる遮熱断熱シートを作成した。本試作品は金属箔を断熱材でサンドイッチしていることにより、外部から入ってくる熱を外側の金属箔で反射させた残りの熱をユニット内の金属箔で反射させた後の熱を内側の金属箔で反射させることにより、特段の遮熱断熱効果が期待できる。サンドイッチユニットを用いないで、単に断熱材を重ねた場合には、断熱材の厚さが増すことによる断熱効果の向上は期待できるが、遮熱効果は従来のものと変わらない。 A polyethylene foam having a thickness of 10 mm and a width of 300 mm was cut with a length of 60 mm and a gap of 5 mm, and expanded to a width of 1000 mm. A high-purity aluminum foil sheet was adhered to one side of the sheet, and then the above polyethylene sheet was adhered to the surface of the high-purity aluminum foil sheet to prepare a heat insulating material-metal foil-heat insulating material unit. Protective coated aluminum foil was adhered to the front and back of the unit, respectively, to create a heat shielding and insulating sheet consisting of a single layer unit. In this prototype, the metal foil is sandwiched between heat insulating materials, so that the heat coming in from the outside is reflected by the outer metal foil, and the remaining heat is reflected by the metal foil inside the unit, and then the heat is transferred to the inside. A special heat insulation effect can be expected by reflecting the light with the metal foil. When the heat insulating material is simply stacked without using the sandwich unit, the heat insulating effect can be expected to be improved by increasing the thickness of the heat insulating material, but the heat shielding effect is the same as that of the conventional one.
本試作品は一般の断熱材より厚みが薄いので空間活用に優れている特徴を有しているうえ、素材が柔らかくて気密密閉施行ができ、窓の空隙や角の熱交換・冷交換減少を遮断して結露やカビの発生を抑える効果が期待できる。従って、別途防湿層を作らなくとも本遮熱・断熱材施行で断熱性、遮熱性及び防湿性を確保できる。さらに、アルミ箔シートの遮音性とポリエチレンフォームの吸音性で防音効果も期待できる。他の断熱材と比較して同じ断熱性基準で、資材費及び施工費が安く、施工期間も短縮できるうえ、薄くて、軽くて、柔らかく、繊維の飛散もなく作業性に優れ、特に角の折れや曲り施工がし易いという特徴がある。 The thickness of this prototype is thinner than that of general insulation materials, so it is excellent in space utilization. In addition, the material is soft and can be airtightly sealed. It can be expected to have the effect of suppressing condensation and mold by blocking it. Therefore, heat insulating properties, heat insulating properties and moisture proof properties can be ensured by applying this heat shielding/insulating material without forming a separate moisture-proof layer. In addition, the sound insulation effect of the aluminum foil sheet and the sound absorption of the polyethylene foam can be expected. Compared to other insulation materials, the material and construction costs are low with the same insulation standards, and the construction period can be shortened. It has the characteristic of being easy to fold and bend.
遮熱・断熱材シートして、建物や構造物の壁の遮熱工事に使用できる。 It can be used as a heat shield/insulation material sheet for heat shield work on the walls of buildings and structures.
