Description

構造体、複層ガラス窓、及び積層体Structures, double glazing windows, and laminates
　本開示は、構造体、複層ガラス窓、及び積層体に関する。 The present disclosure relates to structures, double glazing windows, and laminated bodies.
　周知のように、家屋やビル等の建物に採用される窓の一種として、断熱性能に優れる複層ガラス（例えば特許文献１を参照）を使用した複層ガラス窓がある。 As is well known, as a kind of window used in buildings such as houses and buildings, there is a double glazing window using double glazing having excellent heat insulating performance (see, for example, Patent Document 1).
　複層ガラスは、中空層を挟んで対向する二枚のガラス板と、二枚のガラス板の間隔を保つために、両ガラス板の端部に沿って両ガラス板の相互間に介在するスペーサーと、スペーサーの外周側で二枚のガラス板の端部同士を接着・固定するシーリング材とを備えている。複層ガラスの端部は、グレージングチャンネル等を介して窓の枠体となるサッシに保持される。 Insulated glazing is a spacer that is interposed between two glass plates that face each other with a hollow layer in between and the two glass plates along the edges of both glass plates in order to maintain the distance between the two glass plates. And a sealing material that adheres and fixes the ends of the two glass plates to each other on the outer peripheral side of the spacer. The end portion of the double glazing is held by a sash that serves as a frame of the window via a glazing channel or the like.
　高断熱タイプの複層ガラスでは中空層にアルゴン等の断熱ガスを封止するため、シーリング材として、ガスを通さないポリサルファイド系のシーリング材が一般的に使用されている。ポリサルファイド系のシーリング材には、当該シーリング材に柔軟性を付与するための可塑剤が含まれている。 In high heat insulation type double glazing, a polysulfide type sealing material that does not allow gas to pass through is generally used as a sealing material in order to seal a heat insulating gas such as argon in a hollow layer. The polysulfide-based sealing material contains a plasticizer for imparting flexibility to the sealing material.
特開２０１４－２０２０５５号公報Japanese Unexamined Patent Publication No. 2014-202055
　近年、複層ガラスの軽量化や耐衝撃性の向上等を目的として、複層ガラスを構成するガラス板の代わりに積層体を使用する場合がある。積層体の構造の一例としては、芯材となる樹脂板と薄いガラス板とを接着層を介して重ね合わせた構造が挙げられる。このような積層体を使用することで、ガラス板よりも比重が小さく、物理衝撃にも強いという樹脂板の利点を複層ガラスに好適に活かすことが可能となる。 In recent years, for the purpose of reducing the weight of double glazing and improving impact resistance, a laminated body may be used instead of the glass plate constituting the double glazing. An example of the structure of the laminated body is a structure in which a resin plate as a core material and a thin glass plate are laminated via an adhesive layer. By using such a laminated body, it is possible to suitably utilize the advantages of the resin plate, which has a smaller specific gravity than the glass plate and is resistant to physical impact, to the double glazing.
　しかしながら、上述のごとく積層体を使用した場合には、以下のような解決すべき問題が発生していた。すなわち、積層体の接着層が雰囲気の水分を吸収し、白濁して透明性が損なわれたり、接着力が低下して剥離が発生したりする不具合があった。 However, when the laminated body was used as described above, the following problems to be solved occurred. That is, there is a problem that the adhesive layer of the laminated body absorbs the moisture of the atmosphere and becomes cloudy and the transparency is impaired, or the adhesive force is lowered and peeling occurs.
　なお、上述のような問題は、複層ガラス窓についてのみ発生しているものではない。複層ガラス窓以外の構造体（例えば、鉄道駅のホームドアや、デジタルサイネージカバー等）において、ガラス板の代わりに積層体を使用した場合にも、同様に発生する問題である。 It should be noted that the above-mentioned problems do not occur only in the double glazing window. The same problem occurs when a laminated body is used instead of a glass plate in a structure other than a double glazing window (for example, a platform door of a railway station, a digital signage cover, etc.).
　以上の事情に鑑みて解決すべき技術的課題は、積層体を構成部品とする構造体について、積層体の接着層が雰囲気の水分を吸収するのを防止することである。 In view of the above circumstances, the technical problem to be solved is to prevent the adhesive layer of the laminated body from absorbing the moisture in the atmosphere of the structure having the laminated body as a component.
　上記の課題を解決するための構造体は、板状の芯材と、芯材と接着層を介して重ね合わされたガラス板と、を備えた積層体と、積層体の端部を保持する枠体と、を備えた構造体であって、積層体の端部にて積層体の外表面に露出した接着層の露出部が、金属箔で覆われていることを特徴とする。 The structure for solving the above-mentioned problems is a laminated body including a plate-shaped core material and a glass plate laminated with the core material via an adhesive layer, and a frame for holding an end portion of the laminated body. It is a structure including a body, and is characterized in that an exposed portion of an adhesive layer exposed on the outer surface of the laminated body at an end portion of the laminated body is covered with a metal foil.
　この構造体では、積層体の端部にて積層体の外表面に露出した接着層の露出部が、金属箔で覆われている。これにより、積層体の接着層が雰囲気の水分を吸収するのを防止することが可能となる。 In this structure, the exposed portion of the adhesive layer exposed on the outer surface of the laminate at the end of the laminate is covered with metal foil. This makes it possible to prevent the adhesive layer of the laminated body from absorbing the moisture in the atmosphere.
　上記の構成では、積層体の端部と枠体との間に配置され且つ可塑剤を含んだ被覆部材を備え、接着層の露出部と被覆部材との界面に、金属箔を介在させてもよい。 In the above configuration, a covering member arranged between the end portion of the laminated body and the frame body and containing a plasticizer is provided, and even if a metal foil is interposed at the interface between the exposed portion of the adhesive layer and the covering member. good.
　被覆部材が可塑剤を含んでいる場合、積層体の外表面に露出した接着層の露出部と、被覆部材との界面において、可塑剤が接着層へと染み出して、接着層が変色したり、剥離したりする不具合が発生する恐れがある。しかしながら、接着層の露出部と被覆部材との界面に金属箔を介在させておけば、上述のような恐れを的確に排除することが可能となる。 When the covering member contains a plasticizer, the plasticizer seeps into the adhesive layer at the interface between the exposed portion of the adhesive layer exposed on the outer surface of the laminate and the covering member, and the adhesive layer is discolored. , There is a risk of problems such as peeling. However, if a metal foil is interposed at the interface between the exposed portion of the adhesive layer and the covering member, the above-mentioned fear can be accurately eliminated.
　上記の構成では、被覆部材が可塑剤を含んだシーリング材であることが好ましい。 In the above configuration, it is preferable that the covering member is a sealing material containing a plasticizer.
　このようにすれば、シーリング材によりガス等を通し難くすることが可能であると共に、構造体において積層体を強固に固定できる。 By doing so, it is possible to make it difficult for gas and the like to pass through with the sealing material, and it is possible to firmly fix the laminated body in the structure.
　上記の構成では、芯材が樹脂板を含み、積層体の外表面に露出した樹脂板の露出部が、金属箔で覆われていることが好ましい。 In the above configuration, it is preferable that the core material includes a resin plate and the exposed portion of the resin plate exposed on the outer surface of the laminated body is covered with a metal foil.
　このようにすれば、金属箔の存在により、被覆部材に含まれた可塑剤が樹脂板へと染み出し、樹脂板が変色したり、剥離したりするような恐れを確実に排除できる。 By doing so, it is possible to reliably eliminate the risk that the plasticizer contained in the covering member will seep into the resin plate due to the presence of the metal foil, and the resin plate will be discolored or peeled off.
　上記の構成では、金属箔がアルミニウム箔であることが好ましい。 In the above configuration, it is preferable that the metal foil is an aluminum foil.
　このようにすれば、金属箔として、入手が容易で且つ安価なアルミニウム箔を採用しているため、構造体の製作に掛かるコストを抑制することが可能となる。 In this way, since aluminum foil, which is easily available and inexpensive, is used as the metal foil, it is possible to reduce the cost of manufacturing the structure.
　上記の構成では、金属箔が接着剤により積層体の端部に貼り付けられていることが好ましい。 In the above configuration, it is preferable that the metal foil is attached to the end of the laminate with an adhesive.
　このようにすれば、積層体の端部に対して金属箔を密着させることができるため、接着層や樹脂板への可塑剤の染み出しを、より確実に回避することが可能となる。 By doing so, the metal foil can be brought into close contact with the end of the laminated body, so that it is possible to more reliably prevent the plasticizer from seeping into the adhesive layer or the resin plate.
　上記の構成では、芯材の表面側および裏面側のそれぞれに、接着層を介してガラス板が重ね合わされていることが好ましい。 In the above configuration, it is preferable that glass plates are laminated on each of the front surface side and the back surface side of the core material via an adhesive layer.
　このようにすれば、積層体について、芯材を基準として表面側と裏面側とが対称な構造を有する状態となる。これにより、積層体に反りが発生するような恐れを可及的に排除できる。 By doing so, the laminated body has a symmetrical structure between the front surface side and the back surface side with respect to the core material. As a result, the risk of warping of the laminated body can be eliminated as much as possible.
　また、上記の構造体からなる複層ガラス窓によれば、既述の効果を同様に得ることが可能である。 Further, according to the double glazing window made of the above structure, the above-mentioned effect can be obtained in the same manner.
　また、上記の課題を解決するための積層体は、板状の芯材と、芯材と接着層を介して重ね合わされたガラス板と、を備えた積層体であって、当該積層体の端部にて当該積層体の外表面に露出した接着層の露出部が、金属箔で覆われていることを特徴とする。 Further, the laminated body for solving the above-mentioned problems is a laminated body including a plate-shaped core material and a glass plate laminated with the core material via an adhesive layer, and is an end of the laminated body. The exposed portion of the adhesive layer exposed on the outer surface of the laminated body is covered with a metal foil.
　本積層体では、その端部にて、本積層体の外表面に露出した接着層の露出部が金属箔で覆われている。このため、積層体を構成部品とする構造体（複層ガラス窓等）に本積層体を採用した場合には、既述の効果を同様に得ることができる。 In the present laminate, the exposed portion of the adhesive layer exposed on the outer surface of the present laminate is covered with a metal foil at the end portion thereof. Therefore, when the present laminate is adopted for a structure (multi-layer glass window or the like) having the laminate as a component, the above-mentioned effects can be obtained in the same manner.
　本開示に係る構造体、複層ガラス窓、及び積層体によれば、積層体の接着層が雰囲気の水分を吸収するのを防止することが可能となる。 According to the structure, the double glazing window, and the laminated body according to the present disclosure, it is possible to prevent the adhesive layer of the laminated body from absorbing the moisture in the atmosphere.

　図１は、構造体の一例としての複層ガラス窓１を示す。同図に示すように、複層ガラス窓１は、複層ガラス２と、複層ガラス２の端部に装着されたグレージングチャンネル３と、グレージングチャンネル３を介して複層ガラス２の端部を保持する枠体としてのサッシ４とを備えている。 FIG. 1 shows a double glazing window 1 as an example of a structure.

　複層ガラス２は、中空層５を挟んで対向する積層体６およびガラス板７と、積層体６とガラス板７との間隔を保つために、両者６，７の端部６ａ，７ａに沿って両者６，７の相互間に介在するスペーサー８と、スペーサー８を積層体６およびガラス板７のそれぞれに接着するための一次シーリング材９と、スペーサー８の外周側で積層体６とガラス板７との端部６ａ，７ａ同士を接着・固定するための被覆部材としての二次シーリング材１０と、積層体６の端部６ａを覆う金属テープ１１とを備えている。 The double glazing 2 is formed along the ends 6a and 7a of the laminate 6 and the glass plate 7 facing each other with the hollow layer 5 interposed therebetween in order to maintain a distance between the laminate 6 and the glass plate 7. The spacer 8 is interposed between the two 6 and 7, the primary sealing material 9 for adhering the spacer 8 to each of the laminate 6 and the glass plate 7, and the laminate 6 and the glass plate on the outer peripheral side of the spacer 8. A secondary sealing material 10 as a covering member for adhering and fixing the ends 6a and 7a to the 7 and a metal tape 11 covering the ends 6a of the laminated body 6 are provided.
　中空層５には断熱ガス（例えばアルゴン、空気等）が封止されている。 The hollow layer 5 is sealed with a heat insulating gas (for example, argon, air, etc.).
　積層体６は、芯材となる樹脂板１２と、樹脂板１２の表面側および裏面側のそれぞれに、接着層１３を介して重ね合わされたガラスフィルム１４，１４とを備えている。なお、本実施形態では芯材が単一の樹脂板１２からなるが、これに限定されるものではない。本実施形態の変形例として、複数枚の樹脂板を重ね合わせたものを芯材としてもよい。 The laminated body 6 includes a resin plate 12 as a core material, and glass films 14 and 14 laminated on each of the front surface side and the back surface side of the resin plate 12 via an adhesive layer 13. In the present embodiment, the core material is made of a single resin plate 12, but the core material is not limited to this. As a modification of the present embodiment, a core material may be a stack of a plurality of resin plates.
　樹脂板１２としては、例えばポリカーボネート板を採用できる。ガラスフィルム１４は樹脂板１２よりも一回り小さい面積を有しており、樹脂板１２の端部の全周がガラスフィルム１４の端部から食み出している。これにより、ガラスフィルム１４の端部を衝撃等から好適に保護することが可能である。なお、本実施形態の変形例として、樹脂板１２とガラスフィルム１４とが略同一の面積を有するようにしてもよい。 As the resin plate 12, for example, a polycarbonate plate can be adopted. The glass film 14 has an area one size smaller than that of the resin plate 12, and the entire circumference of the end portion of the resin plate 12 protrudes from the end portion of the glass film 14. This makes it possible to suitably protect the end portion of the glass film 14 from impacts and the like. As a modification of the present embodiment, the resin plate 12 and the glass film 14 may have substantially the same area.
　接着層１３の材質は、例えば、エチレン酢酸ビニル共重合樹脂（ＥＶＡ）、ポリビニルブチラール樹脂（ＰＶＢ）、及びＵＶ硬化樹脂が好適に使用され得るが、その他に、アクリル系粘着剤、シリコーン系粘着剤、ゴム系粘着剤、紫外線硬化性アクリル系接着剤、ウレタン系接着剤、シリコーン系粘着剤、ゴム系粘着剤、紫外線硬化性エポキシ系接着剤、熱硬化性エポキシ系接着剤、熱硬化性メラミン系接着剤、熱硬化性フェノール系接着剤等が使用され得る。 As the material of the adhesive layer 13, for example, ethylene vinyl acetate copolymer resin (EVA), polyvinyl butyral resin (PVB), and UV curable resin can be preferably used, but in addition, an acrylic pressure-sensitive adhesive and a silicone-based pressure-sensitive adhesive can be used. , Rubber adhesive, UV curable acrylic adhesive, Urethane adhesive, Silicone adhesive, Rubber adhesive, UV curable epoxy adhesive, Thermo curable epoxy adhesive, Thermo curable melamine Adhesives, thermosetting phenolic adhesives and the like can be used.
　接着層１３は、一部の部位が積層体６の外表面に露出しており、当該部位が露出部Ｘ（図１に太線で示す部位）を構成している。同様にして、樹脂板１２も一部の部位が積層体６の外表面に露出しており、当該部位が露出部Ｙ（図１に太線で示す部位）を構成している。なお、前述の樹脂板１２とガラスフィルム１４とが略同一の面積を有する変形例では、接着層１３は、積層体６の主表面に露出することなく、積層体６の端面のみに露出するように構成されてもよい。 A part of the adhesive layer 13 is exposed on the outer surface of the laminated body 6, and the portion constitutes the exposed portion X (the portion shown by the thick line in FIG. 1). Similarly, a part of the resin plate 12 is exposed on the outer surface of the laminated body 6, and the portion constitutes the exposed portion Y (the portion shown by the thick line in FIG. 1). In the modified example in which the resin plate 12 and the glass film 14 have substantially the same area, the adhesive layer 13 is not exposed on the main surface of the laminated body 6, but is exposed only on the end surface of the laminated body 6. It may be configured in.
　ガラス板７は、積層体６と略同一の面積を有すると共に、積層体６と略平行となるように配置されている。なお、本実施形態の変形例として、ガラス板７に代えて積層体６を使用してもよい。つまり、中空層５を挟んで二つの積層体６を対向させてもよい。しかしながら、複層ガラス２の剛性を確保する観点では、中空層５を挟んで一方を積層体６とすると共に、他方をガラス板７とすることが好ましい。 The glass plate 7 has substantially the same area as the laminated body 6 and is arranged so as to be substantially parallel to the laminated body 6. As a modification of the present embodiment, the laminated body 6 may be used instead of the glass plate 7. That is, the two laminated bodies 6 may face each other with the hollow layer 5 interposed therebetween. However, from the viewpoint of ensuring the rigidity of the double glazing 2, it is preferable that one is a laminated body 6 and the other is a glass plate 7 with the hollow layer 5 interposed therebetween.
　スペーサー８は中空状に形成されており、内部に乾燥剤１５が充填されている。また、スペーサー８には貫通孔１６が形成されており、貫通孔１６を通じて中空層５からスペーサー８の内部までが連続した空間となっている。そのため、中空層５内の断熱ガスが貫通孔１６を介して乾燥剤１５により乾燥される。 The spacer 8 is formed in a hollow shape, and the desiccant 15 is filled inside. Further, a through hole 16 is formed in the spacer 8, and the space from the hollow layer 5 to the inside of the spacer 8 is a continuous space through the through hole 16. Therefore, the heat insulating gas in the hollow layer 5 is dried by the desiccant 15 through the through hole 16.
　一次シーリング材９は、スペーサー８の側面と積層体６の主面との相互間、及び、スペーサー８の側面とガラス板７の主面との相互間に介在している。 The primary sealing material 9 is interposed between the side surface of the spacer 8 and the main surface of the laminated body 6 and between the side surface of the spacer 8 and the main surface of the glass plate 7.
　二次シーリング材１０はシーリング材である。この二次シーリング材１０にはポリサルファイド系の可塑剤が含まれている。二次シーリング材１０は、積層体６の主面、スペーサー８の外周面、及びガラス板７の主面により形成される凹部に充填されている。さらに、二次シーリング材１０は、積層体６の端面およびガラス板７の端面を外周側から覆っている。なお、本実施形態の変形例として、ポリサルファイド系以外の可塑剤を含んだシーリング材を用いてもよい。 The secondary sealing material 10 is a sealing material. The secondary sealing material 10 contains a polysulfide-based plasticizer. The secondary sealing material 10 is filled in the recess formed by the main surface of the laminated body 6, the outer peripheral surface of the spacer 8, and the main surface of the glass plate 7. Further, the secondary sealing material 10 covers the end surface of the laminated body 6 and the end surface of the glass plate 7 from the outer peripheral side. As a modification of the present embodiment, a sealing material containing a plasticizer other than the polysulfide type may be used.
　金属テープ１１は、積層体６の端部６ａの全周に沿って貼り付けられている。また、金属テープ１１は、積層体６の端部６ａにおいて、積層体６の端面を含め、積層体６の内側主面（内側のガラスフィルム１４の縁部）から外側主面（外側のガラスフィルム１４の縁部）までを連続して覆っている。これにより、金属テープ１１は、接着層１３の露出部Ｘと二次シーリング材１０との界面、及び、樹脂板１２の露出部Ｙと二次シーリング材１０との界面に介在した状態となっている。つまり、露出部Ｘと二次シーリング材１０、及び、露出部Ｙと二次シーリング材１０がそれぞれ金属テープ１１により隔離されて非接触の状態となっている。なお、金属テープ１１における積層体６の外側主面を覆う箇所は省略してもよく、最低限、金属テープ１１が、露出部Ｘと二次シーリング材１０との界面に介在していればよい。 The metal tape 11 is attached along the entire circumference of the end portion 6a of the laminated body 6. Further, in the end portion 6a of the laminated body 6, the metal tape 11 includes the end surface of the laminated body 6 from the inner main surface (edge portion of the inner glass film 14) to the outer main surface (outer glass film) of the laminated body 6. It covers up to the edge of 14) continuously. As a result, the metal tape 11 is interposed at the interface between the exposed portion X of the adhesive layer 13 and the secondary sealing material 10 and the interface between the exposed portion Y of the resin plate 12 and the secondary sealing material 10. There is. That is, the exposed portion X and the secondary sealing material 10 and the exposed portion Y and the secondary sealing material 10 are separated by the metal tape 11 and are in a non-contact state. The portion of the metal tape 11 that covers the outer main surface of the laminated body 6 may be omitted, and at a minimum, the metal tape 11 may be interposed at the interface between the exposed portion X and the secondary sealing material 10. ..
　図２は、複層ガラス窓１の構成部品のうち、積層体６と金属テープ１１のみを示している。同図に示すように、金属テープ１１は、金属箔１１ａと接着剤１１ｂとが重ね合わされてなる。金属箔を構成する金属の種類は、特に限定されるものではないが、本実施形態ではアルミニウム箔を使用している。また、接着剤１１ｂとしては、接着層１３と反応しない接着剤を使用しており、本実施形態ではアクリル系の接着剤を使用している。 FIG. 2 shows only the laminated body 6 and the metal tape 11 among the components of the double glazing window 1. As shown in the figure, the metal tape 11 is formed by superimposing a metal foil 11a and an adhesive 11b. The type of metal constituting the metal foil is not particularly limited, but in the present embodiment, the aluminum foil is used. Further, as the adhesive 11b, an adhesive that does not react with the adhesive layer 13 is used, and in this embodiment, an acrylic adhesive is used.
　図１に示すように、グレージングチャンネル３は、複層ガラス２とサッシ４との間に介在して両者２，４を固定している。グレージングチャンネル３は、例えばポリ塩化ビニル等により構成される。サッシ４は、例えばアルミニウムにより構成される。 As shown in FIG. 1, the glazing channel 3 is interposed between the double glazing 2 and the sash 4 to fix both 2 and 4. The glazing channel 3 is made of, for example, polyvinyl chloride or the like. The sash 4 is made of, for example, aluminum.
　以下、上記の複層ガラス窓１（構造体）による主たる作用・効果について説明する。 Hereinafter, the main actions / effects of the above-mentioned double glazing window 1 (structure) will be described.
　上記の複層ガラス窓１では、積層体６の端部６ａにて積層体６の外表面に露出した接着層１３の露出部Ｘが、金属テープ１１（金属箔１１ａ）で覆われている。これにより、積層体６の接着層１３が雰囲気の水分を吸収するのを防止することが可能となる。また、上記の複層ガラス窓１では、積層体６の外表面に露出した接着層１３の露出部Ｘと二次シーリング材１０との界面に、金属テープ１１（金属箔１１ａ）が介在している。この金属テープ１１の存在により、二次シーリング材１０に含まれた可塑剤が接着層１３へと染み出し、接着層１３が変色したり、剥離したりするような不具合の発生を防止することが可能となる。 In the above-mentioned double glazing window 1, the exposed portion X of the adhesive layer 13 exposed on the outer surface of the laminated body 6 at the end portion 6a of the laminated body 6 is covered with the metal tape 11 (metal foil 11a). This makes it possible to prevent the adhesive layer 13 of the laminated body 6 from absorbing the moisture in the atmosphere. Further, in the above-mentioned double glazing window 1, a metal tape 11 (metal foil 11a) is interposed at the interface between the exposed portion X of the adhesive layer 13 exposed on the outer surface of the laminated body 6 and the secondary sealing material 10. There is. The presence of the metal tape 11 can prevent the plasticizer contained in the secondary sealing material 10 from seeping into the adhesive layer 13 and causing problems such as discoloration or peeling of the adhesive layer 13. It will be possible.
　ここで、上記の実施形態では、構造体として複層ガラス窓を例に挙げて説明したが、この限りではない。例えば、構造体は、鉄道駅のホームドアといった扉であってもよく、デジタルサイネージカバーであってもよい。そして、これら構造体が積層体を構成部品とし、積層体の外表面に露出した接着層の露出部と、可塑剤を含んだ被覆部材（例えば、積層体の端部と、端部を保持する枠体との間に配置されたシーリング材等）とが隣接する構造を有する場合に、露出部と被覆部材との界面に金属箔を介在させるようにしてもよい。 Here, in the above embodiment, a double glazing window has been described as an example as a structure, but this is not the case. For example, the structure may be a door such as a platform door of a railway station, or may be a digital signage cover. Then, these structures have the laminated body as a component, and hold the exposed portion of the adhesive layer exposed on the outer surface of the laminated body and the covering member containing the plasticizer (for example, the end portion and the end portion of the laminated body). When the sealant (such as a sealing material arranged between the frame) has a structure adjacent to the frame, a metal foil may be interposed at the interface between the exposed portion and the covering member.
　以下、構造体の例として、上記の複層ガラス窓１以外の例を挙げる。以下に挙げるスライドドア１７，１８および車両窓１９の説明において、上記の複層ガラス窓１で説明済みの要素と実質的に同一の要素については、スライドドア１７，１８および車両窓１９の説明で参照する図面に同一の符号を付すことで重複する説明を省略している。 Hereinafter, examples of the structure other than the above-mentioned double glazing window 1 will be given. In the description of the sliding doors 17 and 18 and the vehicle window 19 described below, the elements substantially the same as the elements described in the above-mentioned double glazing window 1 are described in the description of the sliding doors 17 and 18 and the vehicle window 19. Duplicate explanations are omitted by assigning the same reference numerals to the referenced drawings.
　図３は、構造体の一例としてのスライドドア１７を示す。本スライドドア１７は、例えばホームドアに用いられ、紙面に対して鉛直な方向にスライドが可能となっている。本スライドドア１７は、積層体６と、積層体６の端部６ａを覆う金属テープ１１と、端部６ａを保持する枠体としてのフレーム２０と、端部６ａとフレーム２０との間に介在した被覆部材としてのシーリング材２１とを備えている。 FIG. 3 shows a sliding door 17 as an example of a structure. The slide door 17 is used, for example, as a platform door, and can slide in a direction perpendicular to the paper surface. The slide door 17 is interposed between the laminated body 6, the metal tape 11 covering the end portion 6a of the laminated body 6, the frame 20 as a frame body for holding the end portion 6a, and the end portions 6a and the frame 20. It is provided with a sealing material 21 as a covering member.
　フレーム２０の上端には開口２０ａが形成されており、開口２０ａを通じて積層体６の端部６ａがフレーム２０内に収容されている。シーリング材２１は、例えばゴムパッキンで構成され、積層体６の端部６ａとフレーム２０との相互間に形成される隙間に充填された状態で金属テープ１１を覆っている。シーリング材２１は、上記の複層ガラス窓１における二次シーリング材１０のごとく可塑剤を含むものであってもよいし、含まないものであってもよい。 An opening 20a is formed at the upper end of the frame 20, and the end portion 6a of the laminated body 6 is housed in the frame 20 through the opening 20a. The sealing material 21 is made of, for example, rubber packing, and covers the metal tape 11 in a state of being filled in a gap formed between the end portion 6a of the laminated body 6 and the frame 20. The sealing material 21 may or may not contain a plasticizer like the secondary sealing material 10 in the double glazing window 1 described above.
　図４は、構造体の一例としてのスライドドア１８を示す。本スライドドア１８が、上記のスライドドア１７と相違している点は、シーリング材２１が金属テープ１１を覆うことなく、金属テープ１１よりも上方でフレーム２０の開口２０ａを塞いでいる点と、積層体６の端面とフレーム２０との相互間にスペーサー２２が介在している点である。 FIG. 4 shows a sliding door 18 as an example of a structure. The difference between the sliding door 18 and the sliding door 17 is that the sealing material 21 does not cover the metal tape 11 and closes the opening 20a of the frame 20 above the metal tape 11. A spacer 22 is interposed between the end face of the laminated body 6 and the frame 20.
　シーリング材２１は、積層体６の周囲とフレーム２０の開口２０ａとの相互間に形成される隙間に充填されている。 The sealing material 21 is filled in the gap formed between the periphery of the laminated body 6 and the opening 20a of the frame 20.
　図５は、構造体の一例としての車両窓１９を示す。本車両窓１９は、ガラス窓の構成部品であるガラス板を積層体に置き換えた窓である。本車両窓１９は、積層体６と、積層体６の端部６ａを覆う金属テープ１１と、端部６ａを保持する枠体としてのフレーム２３と、端部６ａとフレーム２３との間に介在した被覆部材としての押え部材２４とを備えている。 FIG. 5 shows a vehicle window 19 as an example of the structure. The vehicle window 19 is a window in which a glass plate, which is a component of a glass window, is replaced with a laminated body. The vehicle window 19 is interposed between the laminated body 6, the metal tape 11 covering the end portion 6a of the laminated body 6, the frame 23 as a frame body for holding the end portion 6a, and the end portions 6a and the frame 23. It is provided with a pressing member 24 as a covering member.
　フレーム２３の上端には開口２３ａが形成されており、開口２３ａを通じて積層体６の端部６ａがフレーム２３内に収容されている。押え部材２４は、例えばゴムで構成されると共に、積層体６の端部６ａとフレーム２０との相互間に形成される隙間に充填されている。この押え部材２４によって積層体６を押えている。押え部材２４は、上記の複層ガラス窓１における二次シーリング材１０のごとく可塑剤を含むものであってもよいし、含まないものであってもよい。 An opening 23a is formed at the upper end of the frame 23, and the end portion 6a of the laminated body 6 is housed in the frame 23 through the opening 23a. The pressing member 24 is made of, for example, rubber, and is filled in a gap formed between the end portion 6a of the laminated body 6 and the frame 20. The laminated body 6 is pressed by the pressing member 24. The presser member 24 may or may not contain a plasticizer like the secondary sealing material 10 in the double glazing window 1 described above.
　縦×横のサイズが３００ｍｍ×３００ｍｍの積層体を６枚準備し、６枚のうちの３枚については、積層体の端部をアルミニウム箔と接着剤とでなる金属テープで覆うことで実施例とした。一方、残りの３枚については、積層体の端部を金属テープで覆うことなく露出させることで比較例とした。 An example in which six laminated bodies having a vertical × horizontal size of 300 mm × 300 mm are prepared, and for three of the six sheets, the end of the laminated body is covered with a metal tape made of aluminum foil and an adhesive. And said. On the other hand, the remaining three sheets were used as comparative examples by exposing the ends of the laminated body without covering them with metal tape.
　実施例および比較例の積層体の各々を対象として、５５℃の水への浸漬、及び、４０℃の温度下での乾燥を１サイクルとする処理を繰り返し行った。１サイクルあたりの水への浸漬時間は７～１０日間とし、浸漬に伴う積層体の端部の白濁を確認した。１サイクルあたりの乾燥時間は２～３日間とし、乾燥に伴う白濁の消失を確認した。 For each of the laminates of Examples and Comparative Examples, a treatment of immersing in water at 55 ° C. and drying at a temperature of 40 ° C. as one cycle was repeated. The immersion time in water per cycle was 7 to 10 days, and cloudiness at the ends of the laminate due to immersion was confirmed. The drying time per cycle was 2 to 3 days, and the disappearance of cloudiness due to drying was confirmed.
　上記の処理を繰り返し行ったところ、比較例においては、延べ浸漬時間が１７日間に到達した時点で、３枚の積層体の全てで端部に剥離が発生した。これに対して、実施例においては、延べ浸漬時間が３４日間に到達した時点で、ようやく３枚の積層体のうちの１枚で端部に剥離が発生した。 When the above treatment was repeated, in the comparative example, when the total immersion time reached 17 days, peeling occurred at the ends of all three laminated bodies. On the other hand, in the example, when the total immersion time reached 34 days, peeling occurred at the end of one of the three laminated bodies.
　以上のような結果が得られたのは、実施例では積層体の外表面に露出した接着層の露出部が金属テープで覆われていることで、接着層が水分を吸収するのを可及的に防止できたためと推認される。 The above results were obtained in the example because the exposed portion of the adhesive layer exposed on the outer surface of the laminated body was covered with the metal tape, so that the adhesive layer could absorb moisture. It is presumed that it was possible to prevent it.
　上記の［実施例１］と同様にして、実施例となる３枚の積層体と、比較例となる３枚の積層体とを準備した。 In the same manner as in [Example 1] above, three laminated bodies as an example and three laminated bodies as a comparative example were prepared.
　実施例および比較例の各積層体を温度５５℃、湿度９５％の雰囲気下に所定の日数置いた後、５時間以上掛けて３０℃程度の温度まで冷却し、各積層体の端部における白濁および剥離の有無を確認した。 Each of the laminates of Examples and Comparative Examples was placed in an atmosphere of 55 ° C. and 95% humidity for a predetermined number of days, then cooled to a temperature of about 30 ° C. over 5 hours or more, and became cloudy at the end of each laminate. And the presence or absence of peeling was confirmed.
　上記の雰囲気下に１６日間置いた後の確認では、３枚の実施例および３枚の比較例のいずれにおいても白濁および剥離は発生していなかった。しかし、上記の雰囲気下に３２日間置いた後の確認では、３枚の比較例の全てで白濁および剥離が発生していた一方、３枚の実施例のいずれにおいても白濁および剥離は発生していなかった。さらに、３枚の実施例については、上記の雰囲気下に５６日間置いた後の確認でも、未だ白濁および剥離は発生していなかった。 In the confirmation after being placed in the above atmosphere for 16 days, no cloudiness or peeling occurred in any of the three examples and the three comparative examples. However, in the confirmation after being placed in the above atmosphere for 32 days, white turbidity and peeling occurred in all three Comparative Examples, while white turbidity and peeling occurred in all three Examples. There wasn't. Further, with respect to the three examples, white turbidity and peeling did not occur even after confirmation after placing them in the above atmosphere for 56 days.
　以上のような結果が得られたのは、実施例では積層体の外表面に露出した接着層の露出部が金属テープで覆われていることで、接着層が雰囲気の水分を吸収するのを可及的に防止できたためと推認される。 The above results were obtained in the example because the exposed portion of the adhesive layer exposed on the outer surface of the laminated body was covered with the metal tape, so that the adhesive layer absorbed the moisture in the atmosphere. It is presumed that it was possible to prevent it as much as possible.
