Description
本考案は、断熱材に関するものである。 The present invention relates to a heat insulating material.
近年、地球環境問題である温暖化対策として、省エネルギー化を推進する動きが活発になっており、優れた断熱性能を有する断熱材が求められている。その中で、例えば特許文献１に記載されているような硬質ポリウレタンフォームを利用した断熱材が、断熱性、成形性、自己接着性に優れるため住宅や冷凍冷蔵倉庫の建築物、自動販売機や冷蔵庫の機器類の各種断熱材として使用されている。 In recent years, as a measure against global warming, which is a global environmental problem, there is an active movement to promote energy saving, and a heat insulating material having excellent heat insulating performance is demanded. Among them, for example, a heat insulating material using a rigid polyurethane foam as described in Patent Document 1 is excellent in heat insulating properties, moldability, and self-adhesive properties, so that it is a building of a house or a refrigerated warehouse, a vending machine, It is used as various heat insulating materials for refrigerator equipment.
しかしながら、特許文献１記載の断熱材は、硬質ポリウレタンフォームの上下面のみに面材が設けられている板状の断熱材であるため、断熱材の四周(側面)は硬質ポリウレタンフォームが剥き出し状態である。その結果、電気冷蔵庫などの機器にセットする際、予め設置されたキャビネットやドア等の枠内に断熱材を押し込んでセットするが、該フォームの剥き出し部分と外枠等との摩擦により上手くセットできなかったり、該フォームの剥き出し部分が割れや破損を伴い易い問題もあった。 However, since the heat insulating material described in Patent Document 1 is a plate-like heat insulating material in which face materials are provided only on the upper and lower surfaces of the rigid polyurethane foam, the hard polyurethane foam is exposed on the four sides (side surfaces) of the heat insulating material. is there. As a result, when setting to equipment such as an electric refrigerator, the heat insulating material is pushed into a frame such as a cabinet or door set in advance, but it can be set well by friction between the exposed part of the foam and the outer frame. There was also a problem that the exposed portion of the foam was likely to be cracked or damaged.
また、特許文献１記載の断熱材は、面材として合成樹脂フィルムに紙を積層したものを用いているが、硬質ポリウレタンフォームのセル内に内包する発泡剤が経時で面材中の紙を介して大気中の空気と置換する為、断熱性能が劣化してしまう問題があった。 Moreover, although the heat insulating material described in Patent Document 1 uses a laminate of paper on a synthetic resin film as a face material, the foaming agent contained in the cells of the rigid polyurethane foam passes through the paper in the face material over time. Therefore, there is a problem that the heat insulation performance deteriorates because the air in the atmosphere is replaced.
そこで、本考案は、外枠等との組み付け工程に於いて割れや破損を伴わず簡単にセットできると共に、断熱性能が経時で劣化するのを抑制し、長期に亘り安定した断熱性能を発揮する断熱材を提供することを目的とする。 Therefore, the present invention can be easily set without cracking or breakage in the assembly process with the outer frame, etc., suppresses deterioration of the heat insulation performance over time, and exhibits stable heat insulation performance over a long period of time. It aims at providing a heat insulating material.
即ち、本考案の断熱材は、合成樹脂発泡体の全面を面材で被覆してなる断熱材であって、該面材は、該発泡体側から少なくとも合成樹脂フィルム、金属箔の順で積層されてなるものであることを特徴とする。また、前記合成樹脂発泡体が、硬質ポリウレタンフォームであることを特徴とする。 That is, the heat insulating material of the present invention is a heat insulating material obtained by covering the entire surface of a synthetic resin foam with a face material, and the face material is laminated in order of at least a synthetic resin film and a metal foil from the foam side. It is characterized by the above. The synthetic resin foam is a rigid polyurethane foam.
本考案の断熱材は、外枠等との組み付け工程に於いて割れや破損を伴わず簡単にセットできると共に、断熱性能が経時で劣化するのを抑制し、長期に亘り安定した断熱性能を発揮するものである。 The heat insulation material of the present invention can be easily set without cracking or breakage in the assembly process with the outer frame, etc., and suppresses deterioration of the heat insulation performance over time, and exhibits stable heat insulation performance for a long time To do.
本考案の断熱材は、合成樹脂発泡体の全面を面材で被覆してなる断熱材であって、該面材は、該発泡体側から少なくとも合成樹脂フィルム、金属箔の順で積層されてなるものであることを特徴とする。 The heat insulating material of the present invention is a heat insulating material formed by covering the entire surface of a synthetic resin foam with a face material, and the face material is laminated in the order of at least a synthetic resin film and a metal foil from the foam side. It is characterized by being.
本考案の面材は、該発泡体側から少なくとも合成樹脂フィルム、金属箔の順で積層されてなるものである。金属箔は、ガスバリアー性に優れるので硬質ポリウレタンフォーム(或いは、ポリイソシアヌレートフォーム)のセル内に内包する発泡剤が経時で大気中の空気と置換するのを抑制出来る。したがって、該フォームと接触する位置に面材としての金属箔を設けるのが望ましい。ところが、該フォームの持つ自己接着性を利用して一体成形する際、金属箔単独では箔自身が切れたり、該フォームとの接着力が安定しない場合があるので、該フォームと金属箔の間に合成樹脂フィルムを設ける。但し、該フォームのセル内に内包する発泡剤が、合成樹脂フィルムを介して空気と置換しないように薄い合成樹脂フィルムを設けるのが好ましく、具体的には、１０〜５０μｍの薄い合成樹脂フィルムがよい。 The face material of the present invention is formed by laminating at least a synthetic resin film and a metal foil in this order from the foam side. Since the metal foil is excellent in gas barrier properties, it is possible to suppress the foaming agent included in the cells of the rigid polyurethane foam (or polyisocyanurate foam) from being replaced with air in the atmosphere over time. Therefore, it is desirable to provide a metal foil as a face material at a position in contact with the foam. However, when integrally molding using the self-adhesive property of the foam, the metal foil alone may break or the adhesive strength with the foam may not be stable. A synthetic resin film is provided. However, it is preferable to provide a thin synthetic resin film so that the foaming agent included in the cell of the foam does not replace air through the synthetic resin film. Specifically, a thin synthetic resin film of 10 to 50 μm is provided. Good.
また、本考案の面材は、発泡体側から少なくとも合成樹脂フィルム、金属箔の順で積層されているものであるが、金属箔上に合成樹脂フィルム、紙、金属箔等を単独または複数組み合わせて積層させてもよい。尚、本考案の面材として紙を設けることにより、断熱材としての反りを防止したり、剛性を高めることができる。 In addition, the face material of the present invention is one in which at least a synthetic resin film and a metal foil are laminated in this order from the foam side, but the synthetic resin film, paper, metal foil, etc. are combined alone or in combination on the metal foil. It may be laminated. In addition, by providing paper as the face material of the present invention, warpage as a heat insulating material can be prevented or rigidity can be increased.
本考案の合成樹脂フィルムとしては、ポリエチレンフィルム、ポリプロピレンフィルム、ポリエチレンテレフタレートフィルム等のポリエステルフィルム、ポリ塩化ビニルフィルム等が挙げられる。そして、硬質ポリウレタンフォームとの接着性力をより一層安定化させるために、例えばコロナ処理等を行ってもよい。また、金属箔としては、アルミ箔、銅箔、鉄箔、鉛箔等が挙げられ、軽量であるアルミ箔が好ましく使用出来る。紙としては、クラフト紙、ライナー紙、炭酸カルシウム紙、ガラスペーパー、紙状の不織布等が挙げられる。 Examples of the synthetic resin film of the present invention include a polyethylene film, a polypropylene film, a polyester film such as a polyethylene terephthalate film, and a polyvinyl chloride film. In order to further stabilize the adhesive force with the rigid polyurethane foam, for example, a corona treatment or the like may be performed. In addition, examples of the metal foil include aluminum foil, copper foil, iron foil, lead foil and the like, and lightweight aluminum foil can be preferably used. Examples of paper include craft paper, liner paper, calcium carbonate paper, glass paper, and paper-like nonwoven fabric.
本考案の合成樹脂発泡体としては、硬質ポリウレタンフォーム、ポリイソシアヌレートフォーム等が挙げられる。該合成樹脂発泡体の厚みは１０〜１００ｍｍの範囲のものがよく、密度としては２５〜５０ｋｇ／ｍ３のものがよい。 Examples of the synthetic resin foam of the present invention include rigid polyurethane foam and polyisocyanurate foam. The thickness of the synthetic resin foam is preferably in the range of 10 to 100 mm, and the density is preferably 25 to 50 kg / m 3 .
本考案の断熱材は、合成樹脂発泡体の全面を面材で被覆してなる板状のものである。例えば、図１に示すように合成樹脂発泡体の上下面および四周(側面)を面材で被覆した板状のものであり、その結果、経時での断熱性能の低下を抑制するだけでなく、この断熱材を電気冷蔵庫などの機器中の枠内に押し込んでセットする際、外枠との摩擦が軽減されて抵抗が少なくなり簡単にセットできる。また、外枠へ断熱材を無理に押し込む必要がなくなるため、断熱材における端部の割れや破損を軽減することが出来る。 The heat insulating material of the present invention is a plate-like material formed by covering the entire surface of a synthetic resin foam with a face material. For example, as shown in FIG. 1, it is a plate-like material in which the upper and lower surfaces and four sides (side surfaces) of the synthetic resin foam are covered with a face material, and as a result, not only suppresses a decrease in heat insulation performance over time, When this heat insulating material is pushed into a frame in a device such as an electric refrigerator and set, friction with the outer frame is reduced, resistance is reduced, and setting can be performed easily. Further, since it is not necessary to force the heat insulating material into the outer frame, it is possible to reduce the cracks and breakage of the end portions of the heat insulating material.
本発明の断熱材を製造する方法は、例えば図４に示すように注入発泡機のような一般的に不連続パネルを製造する発泡装置によって製造される。注入成形のように予め面材を成形型内に配置して置き一箇所又は数箇所から注入して面材と一体化することが出来る。また、図５に示すようなオープンモールド及び蓋の成形型内側に面材を予め配置しておき、合成樹脂発泡体を注入後に蓋を閉め面材と一体化してもよい。また、面材を予め袋状にして成形型内で断熱材を成形しても良い。発泡機は低圧発泡機や高圧発泡機など一般的に硬質ポリウレタンフォームを発泡できるものは限定無く使用できる。 The method of manufacturing the heat insulating material of the present invention is manufactured by a foaming apparatus that generally manufactures a discontinuous panel such as an injection foaming machine as shown in FIG. Like injection molding, a face material can be placed in a mold in advance and injected from one place or several places to be integrated with the face material. Alternatively, a face material may be arranged in advance in the open mold and the lid mold as shown in FIG. 5, and the lid may be closed and integrated with the face material after the synthetic resin foam is injected. Alternatively, the heat insulating material may be molded in a mold by making the face material into a bag shape in advance. As the foaming machine, those capable of foaming rigid polyurethane foam, such as a low pressure foaming machine and a high pressure foaming machine, can be used without limitation.

続いて、得られた断熱材の熱伝導率と施工性について、実施例１同様の方法で評価を行った。その結果、比較例２で得られた断熱材の熱伝導率は、初期値が０．０２２８Ｗ／（ｍ・Ｋ）であり、経時値が０．０２７３Ｗ／（ｍ・Ｋ）であった。また、施工性は、断熱材端部の割れや破損を伴わず簡単に外枠へセット出来た。 Then, it evaluated by the method similar to Example 1 about the heat conductivity and workability of the obtained heat insulating material. As a result, the thermal conductivity of the heat insulating material obtained in Comparative Example 2 had an initial value of 0.0228 W / (m · K) and a time-dependent value of 0.0273 W / (m · K). In addition, the workability could be easily set on the outer frame without cracking or breaking the edge of the heat insulating material.
以上より、実施例１および２の断熱材は、面材と硬質ポリウレタンフォームとの接着性が良好で、断熱性能が経時で劣化するのを抑制し、長期に亘り安定した断熱性能を発揮する。その上、断熱材端部の割れや破損を伴わず簡単に外枠へセットできる断熱材であった。 From the above, the heat insulating materials of Examples 1 and 2 have good adhesion between the face material and the rigid polyurethane foam, suppress the deterioration of the heat insulating performance over time, and exhibit stable heat insulating performance over a long period of time. In addition, the heat insulating material can be easily set on the outer frame without cracking or breaking the end of the heat insulating material.
比較例１の断熱材は、施工性において外枠との摩擦が軽減されず抵抗が多くなり簡単にセット出来ず、しかも断熱材端部の割れや破損が見られた。比較例２の断熱材は、断熱性能が経時で劣化し、長期に亘り安定した断熱性能を発揮することが出来なかった。 In the heat insulating material of Comparative Example 1, the friction with the outer frame was not reduced in workability, the resistance increased, and the heat insulating material could not be easily set, and cracks and breakage of the end portion of the heat insulating material were observed. In the heat insulating material of Comparative Example 2, the heat insulating performance deteriorated with time, and stable heat insulating performance could not be exhibited over a long period of time.
本考案は、断熱性能が経時で劣化するのを抑制し、長期に亘り安定した断熱性能を発揮すると共に外枠等との組み付け工程に於いて割れや破損が見られず、簡単にセットできる断熱材に関する。 The present invention suppresses deterioration of heat insulation performance over time, exhibits stable heat insulation performance over a long period of time, and does not show cracks or breakage in the assembly process with the outer frame etc. Regarding materials.
