Description
この考案は,複層ガラスの製造及び構造に関するものである。さらに詳しくは,空間部をPIBテープによって保持し,その空間部にアルゴンガス又はクリプトンガスが充填され,かつ,少なくとも片面のガラス内側に透明断熱フィルムが貼付られた,全体の厚みが従来よりも薄い複層ガラスに関するものである。本考案による複層ガラスは,厚みが小さいにもかかわらず断熱性が高いため省エネルギー効果があり,しかも,透明断熱フィルムを直接板ガラスに貼り付けるために傷や劣化が少なく,建物の扉,窓あるいは室内の間仕切り材等として優れた機能を発揮する。 This invention relates to the production and structure of double glazing. More specifically, the space portion is held by PIB tape, the space portion is filled with argon gas or krypton gas, and at least one side of the glass has a transparent heat insulating film adhered to the entire thickness. It relates to a double-glazed glass. The double-glazed glass according to the present invention has an effect of energy saving because of its high heat insulation property despite its small thickness, and because the transparent heat insulation film is directly attached to the plate glass, there is little damage and deterioration, and the door, window or Exhibits an excellent function as an indoor partition material.
(従来の技術)
近年エネルギー資源の有効活用が注目されており,複層ガラスが建築物や保温・保冷容器などにおける省エネルギー性能の向上に資する部材として注目されている。現在製造されている複層ガラスは,2枚のガラス板の間の空間をスペーサーにより保持し,かつ,この空間をシール材により密封し,密封された空間には乾燥空気を封入したり,シリカゲル等の乾燥剤を用いて乾燥状態の保持がなされてきた。また,複層ガラスの省エネルギー効果を向上させるために複層ガラスと透明断熱フィルムとを組み合わせて使用することが最近提案されているが,通常の場合に複層ガラスの空間の厚みは6ミリメートル以上となり,1枚のガラスは一般には3ミリメートルの厚みを有するため,複層ガラス全体の厚みは少なくとも12ミリメートルとなっていた。
(Conventional technology)
In recent years, the effective use of energy resources has attracted attention, and double-glazed glass has attracted attention as a member that contributes to improving energy-saving performance in buildings, heat insulation and cold insulation containers. In the currently manufactured double-glazed glass, the space between the two glass plates is held by a spacer, and this space is sealed with a sealing material, and the sealed space is filled with dry air, silica gel or the like. The drying state has been maintained using a desiccant. In addition, in order to improve the energy saving effect of the double-glazed glass, it has recently been proposed to use a double-glazed glass and a transparent heat insulating film in combination, but the thickness of the double-glazed glass space is usually 6 mm or more. Thus, since one glass generally has a thickness of 3 millimeters, the total thickness of the multilayer glass is at least 12 millimeters.
(考案が解決しようとする課題)
複層ガラスは,通常サッシ枠に挿入した形態で使用される。例えば,飲食物を保管する冷凍・冷蔵ショーケースの扉では,厚みを小さくして収納容積を極力大きくすることが要望されている。また,複層ガラスが厚いとサッシ枠も含めて扉全体が重くなることから,複層ガラスを薄くして,全体の重量を小さくすることが要望される。これらの要望に応えるために複層ガラスに使用するガラス板を薄くする試みがなされているがこれもガラスの強度の点から2.7ミリメートルが限界とされている。
(Problems to be solved by the device)
Multi-layer glass is usually used in a form inserted in a sash frame. For example, a door of a freezer / refrigerated showcase for storing food and drink is required to have a small storage thickness and a large storage capacity. In addition, if the double-glazed glass is thick, the entire door including the sash frame becomes heavy. Therefore, it is desired to make the double-glazed glass thin to reduce the overall weight. In order to meet these demands, attempts have been made to reduce the thickness of the glass plate used for the multilayer glass, but this is also limited to 2.7 millimeters from the viewpoint of the strength of the glass.
そこで,複層ガラスの空間を薄くすることも検討されてきたが,これにより断熱機能が低下することが問題となる。また,複層ガラスの空間保持にはスペーサーが用いられてきたことは前述したが,一般的なスペーサーの構造上最低でも6ミリメートルの間隔が必要となる。このように,単に空間を薄くすることは機能低下を招くことになり,また,従来のスペーサーを使用する限り,構造上複層ガラスの間隔を6ミリメートル未満に抑えることは困難であった。 Therefore, it has been studied to reduce the space of the double-glazed glass, but this causes a problem that the heat insulating function is lowered. In addition, as described above, spacers have been used to maintain the space of the double-glazed glass, but at least a distance of 6 millimeters is required due to the structure of a general spacer. As described above, simply thinning the space causes a decrease in function, and as long as a conventional spacer is used, it is difficult to keep the distance between the double-layered glasses to less than 6 millimeters.
また,複層ガラスの空間部の保持にスペーサーを用いる場合,複層ガラスの製造工程において,スペーサーは少なくとも片面のガラスに実質的に点又は線で接触し,他方のガラス面に面接触することになるが,この際スペーサーは両面接着テープを介して固定化される必要があり,また,複層ガラスの4角におけるスペーサーの4角はジョイント(治具)で固定される必要がある。さらに,スペーサーを用いる場合には,そのスぺーサーの外側においてシール剤を2枚のガラス板の間に充填する必要もある。近年のエコロジー意識の高まりにより複層ガラスの需要が高まる中,複層ガラス製造工程の効率化が求められ,作業工程の簡便化,省力化が必要であるが,スペーサーを用いる構造のままでは,上記のような工程を避けることはできず,簡便化及び省力化にも限界があった。 In addition, when a spacer is used to maintain the space of the double-glazed glass, the spacer should be in contact with at least one side of the glass at a point or a line and in surface contact with the other glass surface in the multi-layer glass manufacturing process. However, in this case, the spacers need to be fixed via double-sided adhesive tape, and the four corners of the spacer in the double-glazed glass need to be fixed by joints (jigs). In addition, when using a spacer, it is necessary to fill the sealing material between the two glass plates outside the spacer. As the demand for double-glazed glass is increasing due to the recent increase in ecology awareness, it is necessary to improve the efficiency of the double-glazed glass manufacturing process, and it is necessary to simplify the work process and save labor. The above processes cannot be avoided, and there are limits to simplification and labor saving.
(課題を解決するための手段)
本考案者は,複層ガラスの構造について種々研究を進めた結果,従来の複層ガラスに用いられてきたスペーサーに代えて,ポリイソブチレンゴムとカーボンブラックにより組成された板状のPIBテープを用いることにより,複層ガラスの間隔を薄くすることができることを見出し先に提案した。
(Means for solving problems)
As a result of various researches on the structure of the double-glazed glass, the present inventor used a plate-like PIB tape composed of polyisobutylene rubber and carbon black instead of the spacer used in the conventional double-glazed glass. Therefore, it was proposed to find out that the interval between the multiple glass layers can be reduced.
この先に提案した考案によれば,少なくとも2枚のガラス板,2枚のガラス板の間の空間部を保持するためのPIBテープにより構成された複層ガラスであって,当該複層ガラスは,2枚のガラス板の間の空間部の厚みが1.5ミリメートルから2.5ミリメートルであることを特徴とする複層ガラスが提供された。 According to the previously proposed device, it is a multi-layer glass composed of PIB tape for holding a space between at least two glass plates and two glass plates, and the multi-layer glass is composed of two sheets. A multilayer glass characterized in that the space between the glass plates has a thickness of 1.5 to 2.5 mm.
(課題を解決するための手段)
考案者は,さらに複層ガラスの空間部の厚みを従来の6ミリメートル以上から,1.5ミリメートルから2.5ミリメートルにまで薄くすることにより生じる断熱機能の低下を補うため,種々の研究を重ねた結果,少なくとも片面のガラス板の内側に透明断熱フィルムを装着した場合には,熱線や紫外線等,有害な光線を遮断もしくは軽減できること等の構造上の特徴があり,この特徴を利用して,複層ガラスの空間部にアルゴンガス又はクリプトンガスを充填する構造と併用することにより,意外にも従来の半分未満の空間部の厚みでも優れた断熱効果の得られる複層ガラスとなることが見出された。
(Means for solving problems)
The inventor has conducted various studies to compensate for the deterioration of the thermal insulation function caused by reducing the thickness of the space of the double-glazed glass from 6 mm or more to 1.5 to 2.5 mm. As a result, when a transparent insulation film is attached inside at least one side of the glass plate, there are structural features such as the ability to block or reduce harmful rays such as heat rays and ultraviolet rays. Surprisingly, it can be seen that by using it together with a structure in which the space of the double-layer glass is filled with argon gas or krypton gas, a double-layer glass can be obtained that has an excellent heat insulation effect even with a thickness of the space that is less than half of the conventional space. It was issued.
すなわち,複層ガラスにおいては,片面のガラス板の内側に透明面発熱体が装着されていることが好ましく,そうすることによって結露を防止乃至抑制することができる。この透明面発熱体をガラス板の内側に装着する方法は,複層ガラスにおいてそれ自体知られている手段を用いることができる。例えば,ガラス板の表面に直接スズやインジュウムの酸化物,金や銀の金属あるいはそれらの合金の被膜をスパッタリング法又は焼結法により形成させる方法であっても良く,また,前記被膜を形成させたフィルムをガラス板に貼り付ける方法であってもよい。透明面発熱体を装着した場合,その面の両端に銀や金などによる電極を取り付け,使用に際しては電圧を印可して表面を加熱し結露を防止することができる。 That is, in the multi-layer glass, it is preferable that the transparent surface heating element is mounted on the inner side of the single-sided glass plate, so that condensation can be prevented or suppressed. As a method of mounting the transparent surface heating element on the inner side of the glass plate, a means known per se in the multi-layer glass can be used. For example, a method of forming a film of tin or indium oxide, gold or silver metal or an alloy thereof directly on the surface of a glass plate by a sputtering method or a sintering method may be used. Alternatively, a method of attaching the film to a glass plate may be used. When a transparent surface heating element is installed, electrodes made of silver or gold can be attached to both ends of the surface, and in use, voltage can be applied to heat the surface and prevent condensation.
また,本考案の複層ガラスの片面のガラス板の内側に透明断熱フィルムを装着して複層ガラスの断熱機能を一層強化することができる。すなわち,本考案の複層ガラスは空間部の厚みが薄いのでそれ自体の断熱効果の不足を補うために透明断熱フィルムの装着は大きな効果を発揮する。透明断熱フィルムはそれ自体市販されており,それをそのまま利用することができる。この断熱フィルムとしては,亜鉛,スズ,金,銀等の金属を蒸着,スパッタリング等の手段でコーティングしたフィルムであって,紫外線,熱線を遮断しうるものである。また,2枚のガラス板は,共に透明のガラス板であることが望ましいが,片面のガラス板は,磨りガラス等の不透明ガラスであっても良い。 In addition, a heat insulating function of the multi-layer glass can be further enhanced by mounting a transparent heat insulating film on the inner side of the single-sided glass plate of the present invention. That is, since the double-glazed glass of the present invention has a thin space portion, the installation of the transparent heat insulating film exhibits a great effect in order to compensate for the lack of its own heat insulating effect. Transparent heat insulation films are commercially available per se and can be used as they are. The heat insulating film is a film in which a metal such as zinc, tin, gold, silver or the like is coated by means such as vapor deposition or sputtering, and can block ultraviolet rays and heat rays. The two glass plates are preferably both transparent glass plates, but the single-sided glass plate may be opaque glass such as polished glass.
さらに,従来の複層ガラスにおいてはガラス板間の空間部には乾燥空気が充填されていたが,熱伝導率を抑えて断熱効果を高めるためには,空気よりも比重の重い気体を空間部に充填することが望ましい。この点,アルゴンガスは比重1.38,クリプトンガスは比重2,89であり,熱伝導率は,空気が0.021kcal/mh℃であるのに対し,アルゴンガスは0.014kcal/mh℃,クリプトンガスは0.00765kcal/mh℃となり,透明断熱フィルムの貼付と複層ガラスの空間部へのアルゴンガス又はクリプトンガスの充填を併用することにより,空間部の厚さが1.5ミリメートル乃至2.5ミリメートル,複層ガラス全体の厚さが7.5ミリメートル乃至8.5ミリメートルという従来の複層ガラスに比して極めて薄い複層ガラスでありながら,従来の複層ガラス以上の優れた断熱効果を得られることが判明した。加えて,本考案の複層ガラスは,透明断熱フィルムがガラスの飛散防止の役割も果たす利点も有する。 Furthermore, in the conventional double-glazed glass, the space between the glass plates was filled with dry air. However, in order to suppress the thermal conductivity and enhance the heat insulation effect, a gas having a higher specific gravity than air is used. It is desirable to fill. In this regard, argon gas has a specific gravity of 1.38, krypton gas has a specific gravity of 2,89, and thermal conductivity is 0.021 kcal / mh ° C for air, whereas argon gas is 0.014 kcal / mh ° C, The krypton gas becomes 0.00765 kcal / mh ° C, and the thickness of the space is 1.5 millimeters to 2 by combining the application of the transparent heat insulating film and the filling of the space of the multilayer glass with argon gas or krypton gas. .5mm, and the total thickness of the multilayer glass is 7.5mm to 8.5mm. Compared with the conventional multilayer glass, it is extremely thin. It turns out that an effect can be obtained. In addition, the multilayer glass of the present invention has an advantage that the transparent heat insulating film also serves to prevent the glass from scattering.
(課題を解決するための手段)
本考案にかかる複層ガラスは,ガラス板間の空間部の保持に,従来のスペーサーを用いず,PIBテープを用いる。PIBテープは,ポリイソブチレンゴム及びカーボンブラックを主成分とするそれ自体が接着力を有する工業用テープであり,シール剤としての効果も発揮する。また,素材の特性上,水蒸気透過率が低く,接着力が長時間維持され,引張り方向に対する追従性に優れている。従来のスペーサーに代わりこのような特性を有するPIBテープを使用することにより,スペーサーを用いる場合には不可避であった各製造工程を省略でき,複層ガラス製造工程を簡略化及び省力化が実現できた。すなわち,PIBテープは,これによりガラス板間の空間部の保持が可能でありながら,それ自体が接着力を有することから,片面のガラス板にPIBテープを面接触させるかたちで貼り付け固定化し,その上から他方のガラス板を接合させるだけで複合ガラスの組立てが可能となり,スペーサーとガラス板を両面接着テープで接合することも,ガラス板の4角におけるスペーサーの4角をジョイントで固定することも不要となった。また,PIBテープ自体がシール剤としての機能も有することから,スペーサーの外側にシール剤を充填する工程も不要となった。
(Means for solving the problem)
The multi-layer glass according to the present invention uses a PIB tape to hold the space between the glass plates without using a conventional spacer. The PIB tape is an industrial tape having a polyisobutylene rubber and carbon black as main components and having an adhesive force as a main component, and also exhibits an effect as a sealing agent. In addition, due to the characteristics of the material, the water vapor permeability is low, the adhesive force is maintained for a long time, and the followability to the tensile direction is excellent. By using a PIB tape with such characteristics in place of conventional spacers, it is possible to omit each manufacturing process that was unavoidable when using spacers, and to simplify and save labor in the multilayer glass manufacturing process. It was. In other words, the PIB tape is capable of holding the space between the glass plates, but has an adhesive force. Therefore, the PIB tape is stuck and fixed to the glass plate on one side in a surface contact manner. It is possible to assemble composite glass by simply joining the other glass plate from above, and joining the spacer and the glass plate with double-sided adhesive tape, or fixing the four corners of the spacer at the four corners of the glass plate with joints Is no longer necessary. In addition, since the PIB tape itself also has a function as a sealant, a step of filling the sealant outside the spacer is unnecessary.
(本考案の効果)
本考案の複層ガラスは,従来の技術では困難であった複層ガラスの空間部の薄型化に成功し,これにより複層ガラス全体の薄型化にも成功したことで,薄型複層ガラスへの産業界からの需要を充足するばかりか,薄型化に成功したことにより,住宅建材として不可欠な審美性にも優れたものとなった。また,透明断熱フィルムの貼付とアルゴンガス又はクリプトンガスの充填という方法を併用することにより,複層ガラスの空間部の薄型化と優れた断熱性能の両立が可能となる。さらに,複層ガラスの製造工程を簡便化,省力化することで,エコロジー社会の中でますますその需要が高まっている複層ガラスの効率的な生産も可能となる。
(Effect of the present invention)
The double-glazed glass of the present invention succeeded in thinning the space of the double-glazed glass, which was difficult with conventional technology, and succeeded in thinning the entire double-glazed glass. As well as satisfying the demand from the industrial world, the company succeeded in reducing the thickness of the product. In addition, by using a method of sticking a transparent heat insulating film and filling with argon gas or krypton gas, it is possible to achieve both a reduction in the thickness of the space of the double-glazed glass and excellent heat insulating performance. In addition, by simplifying the process of manufacturing double-glazed glass and saving labor, it will be possible to efficiently produce double-glazed glass, which is increasingly in demand in the ecological society.
