Description

本発明は、断熱性に優れ、透明性が高くかつ軽量である採光断熱材に関する。 The present invention relates to a daylighting heat insulating material that is excellent in heat insulating properties, high in transparency, and lightweight.

近年の建築物では、省エネルギーの観点から、外界との高い断熱効果を達成し冷暖房の効率を極限にまで高める試みがなされている。このような目的のために断熱性の高い壁材等が種々提案されている。
建築物の住環境等を考える場合に、採光は極めて重要である。現在の建築物においては、採光部にはガラス窓を設置するのが一般的であるが、壁材等に比べて高い断熱効果を発揮させるのは難しかった。「省エネルギー技術戦略報告書」（平成１４年６月１２日、経済産業省）によれば、全消費エネルギーの４５％が窓等の開口部から損失しているといわれている。 In recent years, from the viewpoint of energy saving, attempts have been made to achieve a high heat insulation effect from the outside world and to increase the efficiency of air conditioning to the limit. For this purpose, various wall materials having high heat insulation properties have been proposed.
Daylighting is extremely important when considering the living environment of a building. In the current building, it is common to install a glass window in the daylighting section, but it is difficult to exert a high heat insulating effect compared to wall materials and the like. According to the “Energy Conservation Technology Strategy Report” (June 12, 2002, Ministry of Economy, Trade and Industry), it is said that 45% of all energy consumed is lost through openings such as windows.

断熱性の高いガラスとしては、いわゆるペアガラスが提案されている（例えば、特許文献１等）。ペアガラスは、２枚のガラス間に隙間を設け、ガラス間を真空としたり、アルゴン等の不活性ガスを吹き込んだりしたものであり、ガラス間の空間の存在により、高い断熱効果を発揮しようとするものである。しかしながら、ペアガラスは通常のガラスに比べて重くて嵩張るという問題があった。また、コスト面でも数万〜十数万円／ｍ２かかり、通常の住宅へ応用するのは困難であった。更に、長期間使用する間に空気が侵入して真空状態が破れたり、ガス抜けが起こったりして、性能が低下してしまうことがあるという問題もあった。そこで、断熱性に優れ、透明性が高くかつ軽量である採光断熱材が求められていた。
特開２００３−０２６４５３号公報 As glass with high heat insulation, what is called a pair glass is proposed (for example, patent document 1 etc.). Paired glass is a glass that has a gap between two glass plates and is evacuated or blown with an inert gas such as argon. To do. However, the pair glass has a problem that it is heavier and bulky than ordinary glass. In addition, it costs tens of thousands to hundreds of thousands of yen / m 2 in terms of cost, and is difficult to apply to ordinary houses. Furthermore, there has been a problem that the performance may be deteriorated due to the intrusion of air during a long period of use to break the vacuum state or outgassing. Therefore, there has been a demand for a daylighting heat insulating material that has excellent heat insulating properties, high transparency, and light weight.
Japanese Patent Laid-Open No. 2003-026453

本発明は、上記現状に鑑み、断熱性に優れ、透明性が高くかつ軽量である採光断熱材を提供することを目的とする。 The present invention has been made in view of the above situation, and an object thereof is to provide a daylighting heat insulating material that is excellent in heat insulating properties, is highly transparent, and is lightweight.

本発明は、複数の樹脂フィルムが、空気層を挟んで各々対向した構造を有する採光断熱材であって、可視光線透過率が２０％以上であり、前記空気層は、厚さが１００μｍ〜３ｍｍであり、かつ、少なくともその周辺部が封止されている採光断熱材である。
以下に本発明を詳述する。 The present invention is a daylighting heat insulating material having a structure in which a plurality of resin films face each other across an air layer, and has a visible light transmittance of 20% or more, and the air layer has a thickness of 100 μm to 3 mm. And at least a peripheral part thereof is a daylighting heat insulating material.
The present invention is described in detail below.

本発明の採光断熱材は、複数の樹脂フィルムが、空気層を挟んで各々対向して接着した構造を有する。
本発明の採光断熱材は、２枚の樹脂フィルムの間に空気層が挟持された構成のもの（図１（ａ））であってもよいが、後述する可視光線透過率を満たす限りにおいて、３以上の樹脂フィルムの間に空気層が挟持された構成のもの（図１（ｂ））が好ましい。複数の空気層を有する本発明の採光断熱材は、より高い断熱効果を発揮することができる。 The daylighting heat insulating material of the present invention has a structure in which a plurality of resin films are bonded to each other with an air layer interposed therebetween.
The daylighting heat insulating material of the present invention may have a structure in which an air layer is sandwiched between two resin films (FIG. 1 (a)), as long as the visible light transmittance described later is satisfied. A structure in which an air layer is sandwiched between three or more resin films (FIG. 1B) is preferable. The daylighting heat insulating material of the present invention having a plurality of air layers can exhibit a higher heat insulating effect.

上記樹脂フィルムとしては、透明性に優れるものであれば特に限定されず、例えば、ポリエチレンテレフタレート、ポリカーボネート、ポリエチレン、アクリル、塩化ビニル、ポリビニルアルコール、トリ酢酸セルロース等からなるものが挙げられる。
なかでも、自消性であって建築材として適合性がよいことから、ポリカーボネート、塩化ビニルが好適である。 The resin film is not particularly limited as long as it is excellent in transparency, and examples thereof include those made of polyethylene terephthalate, polycarbonate, polyethylene, acrylic, vinyl chloride, polyvinyl alcohol, cellulose triacetate and the like.
Of these, polycarbonate and vinyl chloride are preferable because they are self-extinguishing and have good compatibility as a building material.

本発明の採光断熱材において、上記樹脂フィルムは全て同じものであってもよいし、各々異なっていてもよい。図２に、各樹脂フィルムが異なる場合における、本発明の採光断熱材の一例の断面を示す模式図を示した。
図２に示した採光断熱材は、２枚のポリエチレンテレフタレートフィルムと、２枚のポリカーボネートフィルムとを、各々の樹脂フィルム間に空気層を挟んでポリカーボネートフィルムが最外層となるように積層した構造を有する。ポリカーボネートフィルムは、強度と耐候性とに優れることから、これ最外層とすることにより防犯性や耐候性を発揮させることができる。また、ポリエチレンテレフタレートフィルムは、機械的強度に優れる。 In the daylighting heat insulating material of the present invention, all of the resin films may be the same or different. In FIG. 2, the schematic diagram which shows the cross section of an example of the lighting insulation material of this invention in case each resin film differs is shown.
The lighting insulation material shown in FIG. 2 has a structure in which two polyethylene terephthalate films and two polycarbonate films are laminated so that the polycarbonate film is the outermost layer with an air layer sandwiched between the resin films. Have. Since the polycarbonate film is excellent in strength and weather resistance, crime prevention and weather resistance can be exhibited by using the polycarbonate film as the outermost layer. Further, the polyethylene terephthalate film is excellent in mechanical strength.

上記樹脂フィルムの厚さとしては特に限定されないが、好ましい下限は１０μｍ、好ましい上限は３００μｍである。１０μｍ未満であると、得られる採光断熱材の強度が劣ることがあり、３００μｍを超えると、同じ断熱効果を得るのに必要以上に採光断熱材が厚くなることがある。より好ましい下限は２０μｍ、より好ましい上限は２００μｍである。 Although it does not specifically limit as thickness of the said resin film, A preferable minimum is 10 micrometers and a preferable upper limit is 300 micrometers. When the thickness is less than 10 μm, the strength of the obtained daylighting heat insulating material may be inferior, and when it exceeds 300 μm, the daylighting heat insulating material may be thicker than necessary to obtain the same heat insulating effect. A more preferable lower limit is 20 μm, and a more preferable upper limit is 200 μm.

上記空気層は、周辺部を封止することにより「動かない空気の層」を形成して高い断熱効果を発揮するものである。
本発明者らは、鋭意検討の結果、空気層の厚さを特定の範囲としたときに、特に高い断熱効果を発揮できることを見出し、本発明を完成するに至った。熱貫通率は空気層の厚さに関係するが、空気層の厚さが０のときには樹脂フィルム自身の熱貫通率に等しく、空気層が充分に厚くなると空気自身の熱貫通率（理論値）に近くなる。ところが、本発明者らが詳細に検討したところ、熱貫通率は、一定の空気層厚のときに極小値を示すことが判った。即ち、空気層の厚さの下限を１００μｍ、上限を３ｍｍとした場合に、特に高い断熱効果が得られることが判った。より好ましい下限は２００μｍ、より好ましい上限は２ｍｍである。
また、このことは、厚い空気層をただ一つだけ有するものよりも、一定の厚さの空気層を複数有するもののほうが断熱効果が高いことを意味している。 The air layer forms a “layer of air that does not move” by sealing the peripheral portion and exhibits a high heat insulating effect.
As a result of intensive studies, the present inventors have found that a particularly high heat insulating effect can be exhibited when the thickness of the air layer is set within a specific range, and have completed the present invention. The thermal penetration rate is related to the thickness of the air layer. When the thickness of the air layer is 0, it is equal to the thermal penetration rate of the resin film itself. When the air layer is sufficiently thick, the thermal penetration rate of the air itself (theoretical value) Close to. However, when the present inventors examined in detail, it turned out that a thermal penetration rate shows the minimum value when it is a fixed air layer thickness. That is, it was found that a particularly high heat insulating effect can be obtained when the lower limit of the air layer thickness is 100 μm and the upper limit is 3 mm. A more preferred lower limit is 200 μm, and a more preferred upper limit is 2 mm.
This also means that the heat insulation effect is higher in the case of having a plurality of air layers having a certain thickness than in the case of having only one thick air layer.

上記空気層は、複数のセルに分割されていることが好ましい。空気層が複数のセルに分割されることにより、本発明の採光断熱材全体の強度を高めることができる。また、個々のセルの独立性、気密性が高まることにより、より高い断熱性能を発揮することができる。
空気層の各セルの大きさの好ましい下限は４ｃｍ２、好ましい上限は１８００ｃｍ２である。４ｃｍ２未満であると、得られる採光断熱材の可視光線透過率が劣ることがあり、１８００ｃｍ２を超えると得られる採光断熱材の強度が劣ることがある。好ましい下限は２５ｃｍ２であり、好ましい上限は６００ｃｍ２である。 The air layer is preferably divided into a plurality of cells. By dividing the air layer into a plurality of cells, the strength of the entire daylighting heat insulating material of the present invention can be increased. Moreover, higher insulative performance can be exhibited by increasing the independence and airtightness of individual cells.
Preferred lower limit is 4 cm 2 in size for each cell in the air layer, the upper limit thereof is preferably 1800 cm 2. When it is less than 4 cm 2 , the visible light insulating material obtained may have inferior visible light transmittance, and when it exceeds 1800 cm 2 , the strength of the obtained lighting insulating material may be inferior. A preferred lower limit is 25 cm 2 and a preferred upper limit is 600 cm 2 .

本発明の採光断熱材は、樹脂フィルム間にスペーサを有することが好ましい。該スペーサは、上記空気層の維持（樹脂フィルム間隔の維持）、空気層の周辺部の封止、空気層の分割等に用いられるものである。 The daylighting insulating material of the present invention preferably has a spacer between the resin films. The spacer is used for maintaining the air layer (maintaining the resin film interval), sealing the periphery of the air layer, dividing the air layer, and the like.

上記スペーサとしては特に限定されないが、採光断熱材の可視光線透過率を確保するために透明であることが好ましく、また、採光断熱材の断熱性能を阻害しないために断熱性が高いものであることが好ましい。このようなスペーサとしては特に限定されないが、例えば、中空体（発泡体を含む）等が好適である。 Although it does not specifically limit as said spacer, In order to ensure the visible light transmittance | permeability of a lighting heat insulating material, it is preferable that it is transparent, and in order not to impair the heat insulation performance of a lighting heat insulating material, it is a thing with high heat insulation. Is preferred. Although it does not specifically limit as such a spacer, For example, a hollow body (a foam is included) etc. are suitable.

上記スペーサの形状としては特に限定されず、粒子状、線状等であってもよいが、上記空気層の周辺部の封止、空気層の分割のためには、格子状のものが好適である。また、上記スペーサの形状により、得られる採光断熱材に意匠性を付与してもよい。なお、上記空気層が複数ある場合には、各々の空気層を規定するスペーサは同一の形状であってもよいし、異なった形状であってもよい。例えば、隣接する空気層を規定するスペーサが直交するようにして、全体としてスペーサが格子状となっていてもよい。 The shape of the spacer is not particularly limited, and may be particulate, linear, or the like, but a lattice-like one is suitable for sealing the periphery of the air layer and dividing the air layer. is there. Moreover, you may provide designability to the obtained lighting heat insulating material with the shape of the said spacer. When there are a plurality of air layers, the spacers defining each air layer may have the same shape or different shapes. For example, the spacers as a whole may have a lattice shape so that the spacers defining adjacent air layers are orthogonal to each other.

本発明の採光断熱材は、可視光線透過率の下限が２０％である。２０％未満であると、充分な採光を得ることができない。好ましい下限は３０％、より好ましい下限は４０％である。 The lower limit of the visible light transmittance of the daylighting heat insulating material of the present invention is 20%. If it is less than 20%, sufficient lighting cannot be obtained. A preferred lower limit is 30%, and a more preferred lower limit is 40%.

本発明の採光断熱材を製造する方法としては特に限定されないが、例えば、図３に記載した態様の製造装置を用いる方法が挙げられる。

In addition, it is preferable to preheat about 50-130 degreeC before laminating | stacking a resin film and a spacer. The resin film and the spacer can be distorted by preheating, and shrinkage and the like can be prevented from occurring after lamination.

本発明の採光断熱材は、また、樹脂フィルム上に、発泡剤を含有する硬化性樹脂組成物（例えば、エポキシ系等熱硬化型硬化性樹脂組成物やウレタン系等反応型硬化性樹脂組成物等）や熱可塑性樹脂組成物を塗工した後、発泡剤を発泡させる方法によっても製造することができる。 The daylighting heat insulating material of the present invention is also a curable resin composition containing a foaming agent on a resin film (for example, an epoxy-based thermosetting curable resin composition or a urethane-based reactive curable resin composition). Etc.) or a thermoplastic resin composition, and then a foaming agent is foamed.

本発明の採光断熱材は、単独で、又は、通常のガラスと併用して建築物の採光部に設置することにより高い断熱性能を発揮することができる。本発明の採光断熱材の設置態様としては特に限定されないが、例えば、通常のガラスによる出窓状の採光部において、該ガラスの内側に該ガラスから離して設置することが考えられる。本発明の採光断熱材を着脱可能なように設置することにより、季節や目的に合わせて本発明の採光断熱材を用いることができる。また、本発明の採光断熱材を、開閉可能な形としてもよい。
本発明の採光断熱材は、また、例えばビニールハウス等の農業用フィルムとしても好適である。 The daylighting heat insulating material of the present invention can exhibit high heat insulating performance by being installed in a daylighting part of a building alone or in combination with ordinary glass. Although it does not specifically limit as an installation aspect of the lighting insulation material of this invention, For example, in the bay window-shaped daylighting part by a normal glass, installing away from this glass inside this glass can be considered.
