Description

複層ガラスDouble glazing
　本発明は、例えば建築物の窓ガラス等に使用される複層ガラスに関する。 The present invention relates to a multi-layer glass used for, for example, a window glass of a building.
　一対のガラス基板を間隙部を介して積層し、該間隙部を真空状態に保持して構成される、いわゆる「真空複層ガラス」は、単一のガラス基板からなるガラス製品に比べて優れた断熱効果を有するため、例えばビルおよび住宅等の建築物用の窓ガラス用途に広く利用されている。
　最近では、真空複層ガラスを構成するガラス基板に化学強化処理を実施することにより、真空複層ガラスの強度を向上させることが開示されている（特許文献１参照）。 A so-called “vacuum double-glazed glass”, which is constructed by laminating a pair of glass substrates through a gap and holding the gap in a vacuum state, is superior to glass products made of a single glass substrate. Since it has a heat insulating effect, it is widely used in window glass applications for buildings such as buildings and houses.
Recently, it has been disclosed to improve the strength of a vacuum double-glazed glass by performing a chemical strengthening process on a glass substrate constituting the vacuum double-glazed glass (see Patent Document 1).

　ところで、従来の真空複層ガラスでは、それぞれのガラス基板は、厚さが少なくとも３．８ｍｍ以上である。従って、両ガラス基板に挟まれた間隙部の厚さを、例えば０．２ｍｍ程度と小さく見積もっても、真空複層ガラスの総厚さは、７．８ｍｍ以上となる。また、このような厚さの真空複層ガラスは、相当の総重量を有することになる。すなわち、従来の真空複層ガラスは、「厚くて重い」という性質がある。 By the way, in the conventional vacuum multilayer glass, each glass substrate has a thickness of at least 3.8 mm or more. Therefore, even if the thickness of the gap portion sandwiched between both glass substrates is estimated to be as small as about 0.2 mm, for example, the total thickness of the vacuum multilayer glass is 7.8 mm or more. Moreover, the vacuum double-glazed glass having such a thickness has a considerable total weight. That is, the conventional vacuum double-glazed glass has the property of being “thick and heavy”.
　このため、このような従来の「厚くて重い」真空複層ガラスは、薄肉化および／または軽量化が必要な用途には適用することが難しく、これが真空複層ガラスのさらなる普及を妨げる一因となっている。
　本発明は、このような背景に鑑みなされたものであり、本発明では、従来の真空複層ガラスに比べて、軽量かつ薄肉化の可能な複層ガラスを提供することを目的とする。 For this reason, such conventional “thick and heavy” vacuum double-glazed glass is difficult to apply to applications that require thinning and / or weight reduction, which is one factor that hinders further spread of vacuum double-glazed glass. It has become.
The present invention has been made in view of such a background, and an object of the present invention is to provide a multilayer glass that is lighter and thinner than a conventional vacuum multilayer glass.

　以下、図面を参照して、本発明について説明する。
　（従来の真空複層ガラス）
　本発明の特徴をより良く理解するため、まず、図１を参照して、従来の真空複層ガラスの構成について簡単に説明する。
　図１には、従来の真空複層ガラスの構成断面図を模式的に示す。 Hereinafter, the present invention will be described with reference to the drawings.
(Conventional vacuum double-layer glass)
In order to better understand the features of the present invention, first, the configuration of a conventional vacuum double-glazed glass will be briefly described with reference to FIG.
FIG. 1 schematically shows a cross-sectional view of a conventional vacuum multi-layer glass.
　図１に示すように、従来の真空複層ガラス１０は、第１のガラス基板１５および第２のガラス基板２５を有する。第１のガラス基板１５は、第１の表面１７および第２の表面１９を有する。第２のガラス基板２５は、第１の表面２７および第２の表面２９を有する。 As shown in FIG. 1, the conventional vacuum multi-layer glass 10 has a first glass substrate 15 and a second glass substrate 25. The first glass substrate 15 has a first surface 17 and a second surface 19. The second glass substrate 25 has a first surface 27 and a second surface 29.
　両ガラス基板１５、２５の間には、間隙部３５が形成されている。間隙部３５は、第１のガラス基板１５の第１の表面１７の外周上、および第２のガラス基板２５の第１の表面２７の外周上に形成された封止部材４５によって、両ガラス基板１５、２５を離間することにより構成される。 A gap 35 is formed between the glass substrates 15 and 25. The gap 35 is formed on both glass substrates by a sealing member 45 formed on the outer periphery of the first surface 17 of the first glass substrate 15 and on the outer periphery of the first surface 27 of the second glass substrate 25. 15 and 25 are separated from each other.
　なお、間隙部３５は、真空状態になっており、間隙部３５には、形状を維持するため、第１のガラス基板１５の第１の表面１７から第２のガラス基板２５の第１の表面２７まで延在する、多数の円柱状のスペーサ４０が配置されている。このようなスペーサ４０を補強材として配置することにより、間隙部３５の形状を維持することができる。 The gap portion 35 is in a vacuum state, and the gap portion 35 has a first surface 17 from the first surface 17 of the first glass substrate 15 to a first surface of the second glass substrate 25 in order to maintain the shape. A large number of cylindrical spacers 40 extending to 27 are arranged. By arranging such a spacer 40 as a reinforcing material, the shape of the gap 35 can be maintained.
　ここで、このような真空複層ガラス１０において、第１および第２のガラス基板１５、２５の厚さは、それぞれ３．８ｍｍ～４．８ｍｍである。また、間隙部３５の厚さ（すなわちスペーサ４０の高さ）は、通常０．１５～１．０ｍｍ程度である。従って、真空複層ガラス１０は、少なくとも７．７５ｍｍの総厚さを有することになる。また、このような真空複層ガラス１０は、相当の重量を有することになる。
　従って、真空複層ガラス１０は、薄肉化および／または軽量化が必要な用途には適用することが難しいという問題がある。 Here, in such a vacuum multilayer glass 10, the thicknesses of the first and second glass substrates 15 and 25 are 3.8 mm to 4.8 mm, respectively. The thickness of the gap portion 35 (that is, the height of the spacer 40) is usually about 0.15 to 1.0 mm. Thus, the vacuum double glazing 10 will have a total thickness of at least 7.75 mm. Moreover, such a vacuum multilayer glass 10 has a considerable weight.
Therefore, there is a problem that the vacuum double-glazed glass 10 is difficult to apply to applications that require thinning and / or lightening.
　例えば、車両には、フロントウィンドウ部材、サイドウィンドウ部材、リアウィンドウ部材、およびルーフウィンドウ部材などの透明または半透明な部材（以下、これらを合わせて「透明部材」と称する）があり、これらの透明部材として、ガラスが使用されている。従って、このような透明部材にも、真空複層ガラス１０を適用することが考えられ得る。しかしながら、「厚くて重い」真空複層ガラス１０を車両の透明部材として適用した場合、車両の燃費が低下してしまう。また、そのような真空複層ガラス１０を保持するためには、別途補強部材が必要となり、部品点数が増加してしまうという問題が生じ得る。
　このように、従来の真空複層ガラス１０は、適用範囲が制限されると言う問題がある。 For example, a vehicle has transparent or semi-transparent members (hereinafter collectively referred to as “transparent members”) such as a front window member, a side window member, a rear window member, and a roof window member. Glass is used as the member. Therefore, it can be considered that the vacuum multilayer glass 10 is applied to such a transparent member. However, when the “thick and heavy” vacuum multilayer glass 10 is applied as a transparent member of a vehicle, the fuel efficiency of the vehicle is reduced. Moreover, in order to hold | maintain such a vacuum multilayer glass 10, a reinforcement member is needed separately and the problem that a number of parts will increase may arise.
Thus, the conventional vacuum multilayer glass 10 has a problem that the application range is limited.
　（本発明による複層ガラスの構成）
　次に、図２を参照して、本発明による複層ガラスの特徴的な構成について説明する。
　図２には、本発明による複層ガラスの一構成例を模式的に示す。
　図２に示すように、本発明による複層ガラス１００は、第１の積層体１１５と、第２の積層体１２５と、両者の間に形成された間隙部１３５とを有する。 (Configuration of double-glazed glass according to the present invention)
Next, a characteristic configuration of the multilayer glass according to the present invention will be described with reference to FIG.
In FIG. 2, one structural example of the multilayer glass by this invention is shown typically.
As shown in FIG. 2, the multilayer glass 100 by this invention has the 1st laminated body 115, the 2nd laminated body 125, and the gap | interval part 135 formed between both.
　第１の積層体１１５は、第１の表面１１７および第２の表面１１９を有する。第２の積層体１２５は、第１の表面１２７および第２の表面１２９を有する。
　間隙部１３５は、第１の積層体１１５の第１の表面１１７の外周上、および第２の積層体１２５の第１の表面１２７の外周上に形成された封止部材１４５によって、両積層体１１５、１２５を離間することにより構成される。ただし、間隙部１３５内は、減圧または真空状態に維持されている。このため、間隙部１３５には、形状を維持するため、具体的には、ほぼ並行な間隔を維持するため、第１の積層体１１５の第１の表面１１７から第２の積層体１２５の第１の表面１２７まで延在する、複数のスペーサ１４０が配置されている。このようなスペーサ１４０を補強材として配置することにより、間隙部１３５の上記形状を維持することができる。 The first stacked body 115 has a first surface 117 and a second surface 119. The second stacked body 125 has a first surface 127 and a second surface 129.
The gap 135 is formed by the sealing member 145 formed on the outer periphery of the first surface 117 of the first stacked body 115 and on the outer periphery of the first surface 127 of the second stacked body 125. 115 and 125 are separated from each other. However, the inside of the gap portion 135 is maintained at a reduced pressure or a vacuum state. Therefore, in order to maintain the shape of the gap portion 135, specifically, to maintain a substantially parallel interval, the first surface 117 of the first stacked body 115 to the second stack 125 of the second stacked body 125. A plurality of spacers 140 extending to one surface 127 are arranged. By disposing such a spacer 140 as a reinforcing material, the shape of the gap 135 can be maintained.
　ここで、第１の積層体１１５は、第１のガラス層１５０、第１のポリカーボネート層１５５、および第２のガラス層１５８を、この順に積層配置することにより構成される。同様に、第２の積層体１２５は、第３のガラス層１６０、第２のポリカーボネート層１６５、および第４のガラス層１６８を、この順に積層配置することにより構成される。 Here, the 1st laminated body 115 is comprised by laminating | stacking the 1st glass layer 150, the 1st polycarbonate layer 155, and the 2nd glass layer 158 in this order. Similarly, the 2nd laminated body 125 is comprised by laminating | stacking the 3rd glass layer 160, the 2nd polycarbonate layer 165, and the 4th glass layer 168 in this order.
　なお、第１の積層体１１５は、第１のガラス層１５０の側が間隙部１３５に近い側となるようにして、間隙部１３５上に配置される。従って、第１の積層体１１５の第１の表面１１７は、第１のガラス層１５０の一方の表面に対応し、第１の積層体１１５の第２の表面１１９は、第２のガラス層１５８の一方の表面に対応する。 The first laminated body 115 is disposed on the gap portion 135 so that the first glass layer 150 side is closer to the gap portion 135. Accordingly, the first surface 117 of the first laminate 115 corresponds to one surface of the first glass layer 150, and the second surface 119 of the first laminate 115 is the second glass layer 158. Corresponds to one of the surfaces.
　同様に、第２の積層体１２５は、第３のガラス層１６０の側が間隙部１３５に近い側となるようにして、間隙部１３５上に配置される。従って、第２の積層体１２５の第１の表面１２７は、第３のガラス層１６０の一方の表面に対応し、第２の積層体１２５の第２の表面１２９は、第４のガラス層１６８の一方の表面に対応する。 Similarly, the second laminated body 125 is disposed on the gap portion 135 so that the third glass layer 160 side is closer to the gap portion 135. Accordingly, the first surface 127 of the second stacked body 125 corresponds to one surface of the third glass layer 160, and the second surface 129 of the second stacked body 125 corresponds to the fourth glass layer 168. Corresponds to one of the surfaces.
　このように、本発明による複層ガラス１００は、第１の積層体１１５が第１のポリカーボネート層１５５を備え、第２の積層体１２５が第２のポリカーボネート層１６５を備えるという特徴を有する。ポリカーボネートは、ガラスに比べて軽い。このため、このような構成とすることにより、第１の積層体１１５および第２の積層体１２５は、それぞれの側に第１の積層体１１５および第２の積層体１２５と同厚の単一のガラス基板１５、２５を使用した場合に比べて、重量を抑制することができる。また、これにより、複層ガラスの総重量を低減することができる。 Thus, the double-glazed glass 100 according to the present invention is characterized in that the first laminate 115 includes the first polycarbonate layer 155 and the second laminate 125 includes the second polycarbonate layer 165. Polycarbonate is lighter than glass. Therefore, by adopting such a configuration, the first stacked body 115 and the second stacked body 125 have a single thickness of the same thickness as that of the first stacked body 115 and the second stacked body 125 on each side. Compared with the case where the glass substrates 15 and 25 are used, the weight can be suppressed. Thereby, the total weight of the multilayer glass can be reduced.
　また、本発明では、第１の積層体１１５において、第１のガラス層１５０および第２のガラス層１５８は、いずれも厚さが０．０５ｍｍ～１．５０ｍｍの範囲にあり、厚さが有意に抑制されているという特徴を有する。同様に、第２の積層体１２５において、第３のガラス層１６０および第４のガラス層１６８は、いずれも厚さが０．０５ｍｍ～１．５０ｍｍの範囲にあり、厚さが有意に抑制されている。なお、第１の積層体１１５における第１のポリカーボネート層１５５の厚さ、および第２の積層体１２５における第２のポリカーボネート層１６５の厚さは、いずれも、０．１０ｍｍ～８．００ｍｍの範囲、より好ましくは、０．５０ｍｍ～３．００ｍｍの範囲である。 In the present invention, in the first laminate 115, the first glass layer 150 and the second glass layer 158 both have a thickness in the range of 0.05 mm to 1.50 mm, and the thickness is significant. It has the characteristic that it is suppressed to. Similarly, in the second laminate 125, each of the third glass layer 160 and the fourth glass layer 168 has a thickness in the range of 0.05 mm to 1.50 mm, and the thickness is significantly suppressed. ing. Note that the thickness of the first polycarbonate layer 155 in the first laminate 115 and the thickness of the second polycarbonate layer 165 in the second laminate 125 are both in the range of 0.10 mm to 8.00 mm. More preferably, it is in the range of 0.50 mm to 3.00 mm.
　また、本発明では、第１の積層体１１５および第２の積層体１２５は、それぞれポリカーボネート層１５５、１６５を有するとともに、厚さが有意に抑制されている。このため、複層ガラス１００の総重量を抑制することができる。
　従って、本発明による複層ガラス１００は、例えば、建築物の窓ガラスや、車両の透明部材のような、薄肉化および／または軽量化が必要な用途においても、制限なく使用することができる。 In the present invention, the first laminate 115 and the second laminate 125 have polycarbonate layers 155 and 165, respectively, and the thickness is significantly suppressed. For this reason, the total weight of the multilayer glass 100 can be suppressed.
Therefore, the double-glazed glass 100 according to the present invention can be used without limitation even in applications that require a reduction in thickness and / or weight, such as a window glass of a building and a transparent member of a vehicle.

　図３に示すように、この複層ガラス１００’は、前述の図２に示した複層ガラス１００とほぼ同様の構成を有する。従って、図３において、図２と同様の構成部材には、図２の構成部材の参照符号が付されている。 In FIG. 3, an example of another structure of the multilayer glass by this invention is shown.
As shown in FIG. 3, this multi-layer glass 100 ′ has substantially the same configuration as the multi-layer glass 100 shown in FIG. Therefore, in FIG. 3, the same reference numerals as those in FIG. 2 are assigned to the same components as those in FIG.
　ただし、この複層ガラス１００’は、第１のガラス層１５０と第１のポリカーボネート層１５５の間に、第１の接着層１５２を有し、第２のガラス層１５８と第１のポリカーボネート層１５５の間に、第２の接着層１５３を有する。また、この複層ガラス１００’は、第３のガラス層１６０と第２のポリカーボネート層１６５の間に、第３の接着層１６２を有し、第４のガラス層１６８と第２のポリカーボネート層１６５の間に、第４の接着層１６３を有する。 However, this double-glazed glass 100 ′ has a first adhesive layer 152 between the first glass layer 150 and the first polycarbonate layer 155, and the second glass layer 158 and the first polycarbonate layer 155. In the meantime, the second adhesive layer 153 is provided. The multilayer glass 100 ′ has a third adhesive layer 162 between the third glass layer 160 and the second polycarbonate layer 165, and the fourth glass layer 168 and the second polycarbonate layer 165. A fourth adhesive layer 163 is provided therebetween.
　第１乃至第４の接着層１５２、１５３、１６２、１６３の厚さは、特に限られない。これらの厚さは、例えば、１．０ｎｍ～１．０ｍｍの範囲であっても良い。かかる接着層としては、ガラス層とポリカーボネート層との接着性に優れ、耐久性、透明性等の本発明の複層ガラスに要求される特性を満たす接着剤、接着膜、粘着剤等の中から適宜のものが選択、使用される。例えば、接着膜としては、ポリビニールブチラール膜、エチレン－酢酸ビニール共重合体膜、シリコーン樹脂膜、ポリ塩化ビニール膜などの接着性合成樹脂膜が挙げられ、また接着剤としては、アクリル、アクリル－スチレン共重合体、エチレン－酢酸ビニール共重合体、エポキシ樹脂、シリコーン樹脂などが挙げられる。
　なお、第１乃至第４の接着層１５２、１５３、１６２、１６３は、必ずしも必要ではなく、この中のいくつかは省略されても良い。
　このような構成の複層ガラス１００’においても、前述の図２に示した複層ガラス１００と同様の効果が得られることができる。 The thickness of the first to fourth adhesive layers 152, 153, 162, 163 is not particularly limited. These thicknesses may be in the range of 1.0 nm to 1.0 mm, for example. As such an adhesive layer, the adhesive between the glass layer and the polycarbonate layer is excellent, and from among adhesives, adhesive films, pressure-sensitive adhesives, etc. that satisfy the properties required for the multilayer glass of the present invention such as durability and transparency An appropriate one is selected and used. For example, examples of the adhesive film include an adhesive synthetic resin film such as a polyvinyl butyral film, an ethylene-vinyl acetate copolymer film, a silicone resin film, and a polyvinyl chloride film, and examples of the adhesive include acrylic, acrylic- Examples include styrene copolymers, ethylene-vinyl acetate copolymers, epoxy resins, and silicone resins.
Note that the first to fourth adhesive layers 152, 153, 162, and 163 are not necessarily required, and some of them may be omitted.
Also in the double-glazed glass 100 ′ having such a configuration, the same effect as that of the double-glazed glass 100 shown in FIG. 2 described above can be obtained.
　（本発明による複層ガラスの構成部材の仕様）
　以下、本発明による複層ガラス１００を構成する各部材について、より詳しく説明する。
　（第１の積層体）
　以下、第１の積層体１１５の構成について説明するが、第２の積層体１２５の構成においても、以下に説明する第１の積層体と同様の構成を適用することができる。従って、第２の積層体１２５の構成についての説明は、省略する。
　第１の積層体１１５は、第１のガラス層１５０、第１のポリカーボネート層１５５、および第２のガラス層１５８を有する。なお、第２のガラス層１５８は、第１のガラス層１５０と同様の構成であっても良いため、以下、第１のガラス層１５０の構成を例に説明する。 (Specifications of components of the multilayer glass according to the present invention)
Hereinafter, each member which comprises the multilayer glass 100 by this invention is demonstrated in detail.
(First laminate)
Hereinafter, although the structure of the 1st laminated body 115 is demonstrated, also in the structure of the 2nd laminated body 125, the structure similar to the 1st laminated body demonstrated below is applicable. Therefore, description of the configuration of the second stacked body 125 is omitted.
The first laminated body 115 includes a first glass layer 150, a first polycarbonate layer 155, and a second glass layer 158. Note that the second glass layer 158 may have a configuration similar to that of the first glass layer 150, and therefore, the configuration of the first glass layer 150 will be described below as an example.
　（第１のガラス層）
　第１のガラス層１５０は、表裏のそれぞれに相当する主表面（第１の主表面および第２の主表面）を有する。第１のガラス層１５０は、前記したように０．０５ｍｍ～１．５０ｍｍの範囲の厚さを有するガラス板よりなる。
　第１のガラス層１５０は、ソーダライムシリカガラスをはじめとし、いかなる組成のガラス材で構成されても良い。また、第１のガラス層の厚さは、前述のように、０．０５ｍｍ～１．５０ｍｍの範囲のものが選ばれる。
　また、第１のガラス層１５０は、少なくとも一部が化学強化処理されていても良い。 (First glass layer)
First glass layer 150 has main surfaces (first main surface and second main surface) corresponding to the front and back surfaces. As described above, the first glass layer 150 is made of a glass plate having a thickness in the range of 0.05 mm to 1.50 mm.
The first glass layer 150 may be made of a glass material having any composition including soda lime silica glass. The thickness of the first glass layer is selected from the range of 0.05 mm to 1.50 mm as described above.
Further, at least a part of the first glass layer 150 may be chemically strengthened.
　ここで、「化学強化処理（法）」とは、ガラス板を、アルカリ金属を含む溶融塩中に浸漬させ、ガラス板の最表面に存在する原子径の小さなアルカリ金属（イオン）を、溶融塩中に存在する原子径の大きなアルカリ金属（イオン）と置換する技術の総称を言う。「化学強化処理（法）」では、処理されたガラス板の表面には、元の原子よりも原子径の大きなアルカリ金属（イオン）が配置される。このため、ガラス板の表面に圧縮応力を付与することができ、これによりガラス板の強度（特にワレ強度）が向上する。 Here, “chemical strengthening treatment (method)” means that a glass plate is immersed in a molten salt containing an alkali metal, and an alkali metal (ion) having a small atomic diameter present on the outermost surface of the glass plate is used as a molten salt. This is a generic term for technologies that replace alkali metals (ions) with a large atomic diameter. In the “chemical strengthening treatment (method)”, an alkali metal (ion) having an atomic diameter larger than that of the original atoms is arranged on the surface of the treated glass plate. For this reason, compressive stress can be given to the surface of a glass plate, and the intensity | strength (especially crack strength) of a glass plate improves by this.
　例えば、ガラス板がナトリウム（Ｎａ）を含む場合、化学強化処理により、このナトリウムは、例えばカリウム（Ｋａ）と置換される。あるいは、例えば、ガラス板がリチウム（Ｌｉ）を含む場合、化学強化処理により、このリチウムは、例えばナトリウム（Ｎａ）および／またはカリウム（Ｋａ）と置換されても良い。 For example, when a glass plate contains sodium (Na), this sodium is replaced with, for example, potassium (Ka) by chemical strengthening treatment. Alternatively, for example, when the glass plate contains lithium (Li), this lithium may be replaced with, for example, sodium (Na) and / or potassium (Ka) by chemical strengthening treatment.
　化学強化処理される領域は、特に限られない。例えば、第１のガラス層１５０は、実質的に、全露出表面が化学強化処理されても良い。また、例えば、第１のガラス層１５０は、一方の主表面のみが化学強化処理されていても良い。
　なお、第１のガラス層１５０を化学強化処理する場合、第１のガラス層１５０は、リチウム、ナトリウムおよび／またはカリウムのようなアルカリ金属を含む組成のガラス材で構成されることが特に好ましい。 The area to be chemically strengthened is not particularly limited. For example, substantially the entire exposed surface of the first glass layer 150 may be chemically strengthened. In addition, for example, only one main surface of the first glass layer 150 may be chemically strengthened.
When the first glass layer 150 is chemically strengthened, the first glass layer 150 is particularly preferably formed of a glass material having a composition containing an alkali metal such as lithium, sodium and / or potassium.
　第１のガラス層１５０の製造方法は、特に限られない。第１のガラス層１５０は、例えば、フロート法、フュージョン法、およびリドロー法等の、ガラス板の一般的な製造方法により製造されても良い。
　前述のように、第１のガラス層１５０の厚さは、０．０５ｍｍ～１．５０ｍｍの範囲であり、０．１０ｍｍ～０．７０ｍｍの範囲であることが好ましい。
　以上、第１のガラス層の構成について説明したが、第２、第３および第４のガラス層についても、第１のガラス層と同様な構成のものが使用できる。 The manufacturing method of the first glass layer 150 is not particularly limited. The first glass layer 150 may be manufactured by a general method for manufacturing a glass plate, such as a float method, a fusion method, and a redraw method.
As described above, the thickness of the first glass layer 150 is in the range of 0.05 mm to 1.50 mm, and preferably in the range of 0.10 mm to 0.70 mm.
Although the configuration of the first glass layer has been described above, the same configuration as that of the first glass layer can be used for the second, third, and fourth glass layers.
　（第１のポリカーボネート層）
　第１のポリカーボネート層１５５は、前述のように、０．１０ｍｍ～８．００ｍｍの範囲の厚さを有し、この厚さは、０．５０ｍｍ～３．００ｍｍの範囲であることが好ましい。第２のポリカーボネート層も、第１のポリカーボネート層と同様な構成のものが使用できる。 (First polycarbonate layer)
As described above, the first polycarbonate layer 155 has a thickness in the range of 0.10 mm to 8.00 mm, and this thickness is preferably in the range of 0.50 mm to 3.00 mm. The 2nd polycarbonate layer can use the thing of the same composition as the 1st polycarbonate layer.
　第１の積層体１１５を構成する方法は、特に限られない。例えば、第１のガラス層１５０、第１のポリカーボネート層１５５、および第２のガラス層１５８を相互に形成しておいてから、これらを例えば接着材を介して貼り合わせることにより、第１の積層体１１５を構成しても良い。あるいは、２枚のガラス層１５０、１５８を間隔を開けて配置しておき、両者の間の空間に、ポリカーボネートの加熱溶融物あるいは流動物を射出成形しても良い。その後、この加熱溶融物あるいは流動物が固化して、ポリカーボネート層１５５が形成される。この方法では、加熱溶融物あるいは流動物の熱収縮力により、ポリカーボネート層１５５が形成される際に、両側のガラス層１５０、１５８が相互に内側に引き寄せられる。このため、この方法で製造した積層体では、完成後に、各部材間に高い密着強度が得られる。 The method for configuring the first laminate 115 is not particularly limited. For example, the first glass layer 150, the first polycarbonate layer 155, and the second glass layer 158 are formed on each other, and then bonded to each other through, for example, an adhesive, so that the first laminated layer is formed. The body 115 may be configured. Alternatively, the two glass layers 150 and 158 may be arranged with a space therebetween, and a polycarbonate hot melt or fluid may be injection molded into the space between them. Thereafter, the heated melt or fluid is solidified to form a polycarbonate layer 155. In this method, when the polycarbonate layer 155 is formed by the heat shrinkage force of the heated melt or fluid, the glass layers 150 and 158 on both sides are attracted toward each other. For this reason, in the laminated body manufactured by this method, high adhesion strength is obtained between each member after completion.
　（間隙部１３５）
　第１の積層体１１５と第２の積層体１２５の間には、間隙部１３５が形成される。間隙部１３５内の圧力は、通常、１．３３Ｐａ以下である。また、間隙部１３５の厚さは、通常の場合、０．１５ｍｍ～１．０ｍｍ程度である。
　間隙部は、第１の積層体１１５と第２の積層体１２５の外周に沿って配置された封止部材１４５と、内部に、所定の間隔で、規則的または不規則に配置された複数のスペーサ１４０とを有する。 (Gap 135)
A gap 135 is formed between the first stacked body 115 and the second stacked body 125. The pressure in the gap 135 is usually 1.33 Pa or less. Further, the thickness of the gap 135 is usually about 0.15 mm to 1.0 mm.
The gap portion includes a plurality of sealing members 145 arranged along the outer peripheries of the first laminated body 115 and the second laminated body 125, and a plurality of regularly or irregularly arranged therein at a predetermined interval. Spacer 140.
　（封止部材１４５）
　第１の積層体１１５の第１の表面１１７の周縁部、および第２の積層体１２５の第１の表面１２７の周縁部において、第１および第２の積層体１１５、１２５を所定間隔をもって離間し、封止するために設けられる封止部材１４５は、通常、前記第１のガラス層の表面と第３のガラス層との接着強度が２０ｋｇ／ｃｍ２以上の特性を持つものが好ましい。
　封止部材１４５の材質は、間隙部１３５を外界から遮断し、真空または減圧状態を維持することができる限り、特に限られない。例えば、封止部材１４５の材質として、封着温度が２５０℃未満の低融点のガラスフリットを使用しても良い。あるいは、封止部材１４５は、鉛、スズ、亜鉛、インジウム等を主成分とする金属ハンダが使用されても良い。特に、ガラス製の封止部材１４５を使用した場合、最終的に得られる複層ガラス１００において、外枠に透明な美感を得ることができる。 (Sealing member 145)
The first and second stacked bodies 115 and 125 are separated from each other at a predetermined interval at the peripheral edge of the first surface 117 of the first stacked body 115 and the peripheral edge of the first surface 127 of the second stacked body 125. In general, the sealing member 145 provided for sealing preferably has a property that the adhesive strength between the surface of the first glass layer and the third glass layer is 20 kg / cm 2 or more.
The material of the sealing member 145 is not particularly limited as long as it can block the gap 135 from the outside and maintain a vacuum or a reduced pressure state. For example, a glass frit having a low melting point with a sealing temperature lower than 250 ° C. may be used as the material of the sealing member 145. Alternatively, the sealing member 145 may be made of metal solder whose main component is lead, tin, zinc, indium or the like. In particular, when a glass sealing member 145 is used, a transparent aesthetics can be obtained on the outer frame in the finally obtained multilayer glass 100.
　（スペーサ１４０）
　スペーサ１４０は、所定の圧縮強度（例えば４．９×１０８Ｐａ以上の圧縮強度）を有する限り、いかなる材質で構成されても良い。スペーサ１４０は、例えば、鉄、ニッケル、クロム、銅、アルミニウム、およびチタンのような純金属、炭素鋼、クロム鋼、ニッケル鋼、ステンレス鋼、インコネル合金、およびジュラルミンのような合金材料、セラミックスおよびガラスのような無機材料、ならびに樹脂のような有機材料で構成されても良い。 (Spacer 140)
The spacer 140 may be made of any material as long as it has a predetermined compressive strength (for example, a compressive strength of 4.9 × 10 8 Pa or more). The spacer 140 is made of, for example, pure metals such as iron, nickel, chromium, copper, aluminum, and titanium, carbon steel, chromium steel, nickel steel, stainless steel, inconel alloy, and alloy materials such as duralumin, ceramics, and glass. It may be composed of an inorganic material such as, and an organic material such as a resin.
　特に、スペーサ１４０を透明な材料（例えば、ガラスおよび／または樹脂）で構成した場合、スペーサ１４０があまり目立たなくなり、複層ガラス１００の美感が向上するという効果が得られる。
　スペーサ１４０の配置形態は、特に限られない。スペーサ１４０は、例えば、縦横に一定の間隔で、規則的に配置されても良い。 In particular, when the spacer 140 is made of a transparent material (for example, glass and / or resin), the spacer 140 becomes less conspicuous and the effect of improving the aesthetics of the multilayer glass 100 is obtained.
The arrangement form of the spacer 140 is not particularly limited. For example, the spacers 140 may be regularly arranged at regular intervals in the vertical and horizontal directions.
　図４および図５には、スペーサ１４０の配置形態の一例を概略的に示す。
　図４において、各スペーサ１４０は、複数の行Ｘ１～Ｘ６（ピッチＰ１）および複数の列Ｙ１～Ｙ８（ピッチＰ２）を構成するように配置されている。ここで、任意の行をiとしたとき、隣接する行ＸｉとＸ（ｉ＋１）において、スペーサ１４０のＸ方向の座標は、等しくなっている（ここでｉは１以上の整数。以下同じ）。同様に、任意の列をiとしたとき、隣接する列ＹｉとＹ（ｉ＋１）において、スペーサ１４０のＹ方向の座標は、等しくなっている。 4 and 5 schematically show an example of the arrangement form of the spacers 140. FIG.
In FIG. 4, each spacer 140 is arranged so as to constitute a plurality of rows X 1 to X 6 (pitch P 1 ) and a plurality of columns Y 1 to Y 8 (pitch P 2 ). Here, when an arbitrary row is i, in the adjacent rows X i and X (i + 1) , the coordinates of the spacer 140 in the X direction are equal (where i is an integer of 1 or more, and so on). . Similarly, when an arbitrary column is i, in the adjacent columns Y i and Y (i + 1) , the coordinates of the spacer 140 in the Y direction are equal.
　一方、図５においても、各スペーサ１４０は、複数の行Ｘ１～Ｘ７および複数の列Ｙ１～Ｙ８を構成するように配置されている。ただし、この例では、任意の行をiとしたとき、隣接する行ＸｉとＸ（ｉ＋１）において、スペーサ１４０のＸ方向の座標は、異なっており、スペーサ１４０は、一行置きに、すなわち行ＸｉとＸ（ｉ＋２）において、スペーサ１４０のＸ方向の座標が揃うようにして配置されている。また、任意の列をiとしたとき、隣接する列Ｙｉと列Ｙ（ｉ＋１）において、スペーサ１４０のＹ方向の座標は、異なっており、スペーサ１４０は、一列置きに、すなわち列ＹｉとＹ（ｉ＋２）において、スペーサ１４０のＹ方向の座標が揃うようにして配置されている。 On the other hand, also in FIG. 5, each spacer 140 is arranged so as to constitute a plurality of rows X 1 to X 7 and a plurality of columns Y 1 to Y 8 . However, in this example, when an arbitrary row is i, the coordinates in the X direction of the spacers 140 in the adjacent rows X i and X (i + 1) are different, and the spacers 140 are arranged every other row, that is, the rows. In X i and X (i + 2) , the spacers 140 are arranged so that the coordinates in the X direction are aligned. In addition, when an arbitrary column is i, the coordinate in the Y direction of the spacer 140 is different between the adjacent column Y i and the column Y (i + 1) , and the spacer 140 is arranged every other column, that is, the column Y i and the column Y i . In Y (i + 2) , the spacers 140 are arranged so that the coordinates in the Y direction are aligned.
　なお、スペーサ１４０の配置間隔Ｐ１およびＰ２は、例えば、２０ｍｍ～５０ｍｍ程度である。
　この他にも様々な形態で、スペーサ１４０を配置しても良い。
　スペーサ１４０の形状は、特に限られない。スペーサ１４０は、例えば、円柱状、楕円柱状、角柱状、球状、鼓状、樽状、および／またはソロバン玉状の形状を有しても良い。 Note that the arrangement intervals P 1 and P 2 of the spacer 140 are, for example, about 20 mm to 50 mm.
In addition, the spacer 140 may be arranged in various forms.
The shape of the spacer 140 is not particularly limited. The spacer 140 may have, for example, a cylindrical shape, an elliptical columnar shape, a prismatic shape, a spherical shape, a drum shape, a barrel shape, and / or a abacus ball shape.
　スペーサ１４０の太さ（例えば、円柱状の場合における直径）は、例えば、０．３ｍｍ～１．０ｍｍ程度である。また、スペーサ１４０の高さは、例えば、０．１５ｍｍ～１．０ｍｍ程度である。ただし、これらの数値は、スペーサ１４０の材質（例えば、強度）および配置形態等に依存し、必要な強度確保の観点から定められる。 The thickness of the spacer 140 (for example, the diameter in the case of a cylindrical shape) is, for example, about 0.3 mm to 1.0 mm. The height of the spacer 140 is, for example, about 0.15 mm to 1.0 mm. However, these numerical values depend on the material (for example, strength) of the spacer 140, the arrangement form, and the like, and are determined from the viewpoint of securing the necessary strength.
　（複層ガラス１００）
　前述のように、複層ガラス１００は、第１の積層体１１５および第２の積層体１２５を有する。また、第１の積層体１１５に含まれる第１のガラス層１５０、および第２の１５８は、少なくとも一部が化学強化処理されていても良い。第２の積層体１２５に含まれる第３のガラス層１６０、第４のガラス層１６８についても同様である。 (Multilayer glass 100)
As described above, the multilayer glass 100 includes the first laminated body 115 and the second laminated body 125. In addition, at least a part of the first glass layer 150 and the second 158 included in the first stacked body 115 may be chemically strengthened. The same applies to the third glass layer 160 and the fourth glass layer 168 included in the second stacked body 125.
　ここで、強度向上の点からは、化学強化処理は、全てのガラス層１５０、１５８、１６０、１６８について、実施されていることが好ましい。しかしながら、この場合、製造コストが上昇する。
　あるいは、化学強化処理は、複層ガラス１００の両外側表面、すなわち第１の積層体１１５の第２の表面１１９側（すなわち、第２のガラス層１５８の露出表面に相当する側）、および第２の積層体１２５の第２の表面１２９側（すなわち、第４のガラス層１６８の露出表面に相当する側）に、実施されていても良い。この場合、複層ガラス１００の傷および摩耗に対する耐性が向上する。 Here, from the viewpoint of strength improvement, it is preferable that the chemical strengthening treatment is performed for all the glass layers 150, 158, 160, and 168. However, in this case, the manufacturing cost increases.
Alternatively, the chemical strengthening treatment is performed on both outer surfaces of the multilayer glass 100, that is, on the second surface 119 side of the first laminated body 115 (that is, on the side corresponding to the exposed surface of the second glass layer 158), and The second laminated body 125 may be implemented on the second surface 129 side (that is, the side corresponding to the exposed surface of the fourth glass layer 168). In this case, the resistance to scratches and abrasion of the multilayer glass 100 is improved.
　あるいは、化学強化処理は、第１の積層体１１５の第１の表面１１７側（すなわち、第１のガラス層１５０の間隙部１３５に近い表面に相当する側）、および第２の積層体１２５の第１の表面１２７側（すなわち、第３のガラス層１６０の間隙部１３５に近い表面に相当する側）に、実施されていても良い。この場合、ガラス層の強度が向上し、間隙部１３５に配置されるスペーサ１４０の数を低減することができるため、複層ガラス１００の断熱性が向上する。 Alternatively, the chemical strengthening treatment is performed on the first surface 117 side of the first laminated body 115 (that is, the side corresponding to the surface close to the gap 135 of the first glass layer 150) and the second laminated body 125. It may be carried out on the first surface 127 side (that is, the side corresponding to the surface close to the gap 135 of the third glass layer 160). In this case, the strength of the glass layer is improved, and the number of spacers 140 disposed in the gap portion 135 can be reduced, so that the heat insulating property of the multilayer glass 100 is improved.
　また、複層ガラス１００を構成する第１のガラス層、第２のガラス層、第３のガラス層、第４のガラス層、第１のポリカーボネート層、第２のポリカーボネート層、第１の接着層、第２の接着層、第３の接着層、および第４の接着層のうちの少なくとも一層に対し、更なる機能を付与してもよい。
　かかる機能としては、低放射性、紫外線遮蔽性、熱線遮蔽性、低反射性、撥水性、防曇性、調光、防眩性、遮音性、防汚性、導電性、および帯電防止性からなる群から選定された少なくとも一種が挙げられる。 The first glass layer, the second glass layer, the third glass layer, the fourth glass layer, the first polycarbonate layer, the second polycarbonate layer, and the first adhesive layer constituting the multilayer glass 100. Further functions may be imparted to at least one of the second adhesive layer, the third adhesive layer, and the fourth adhesive layer.
Such functions include low radiation, ultraviolet shielding, heat ray shielding, low reflectivity, water repellency, antifogging, dimming, antiglare, sound insulation, antifouling, electrical conductivity, and antistatic properties. At least one selected from the group.
　また、複層ガラス１００は、さらに、少なくとも一つの機能層を有しても良い。
　機能層は、目的に応じて所望の機能を有する層が選ばれるが、例えば、低放射性層、紫外線遮蔽性層、熱線遮蔽性層、低反射性層、撥水性層、防曇性層、調光層、防眩性層、遮音性層、防汚性層、導電性層、帯電防止性層、および保護層からなる群から選ばれる少なくとも１種であっても良い。
　より具体的には、上記した機能層は、本発明の複層ガラスを構成する第１のガラス層、第２のガラス層、第３のガラス層、第４のガラス層、第１のポリカーボネート層、第２のポリカーボネート層、第１の接着層、第２の接着層、第３の接着層、および第４の接着層のうちの少なくとも一層に形成することができる。 The multilayer glass 100 may further include at least one functional layer.
As the functional layer, a layer having a desired function is selected according to the purpose. For example, a low radiation layer, an ultraviolet shielding layer, a heat ray shielding layer, a low reflection layer, a water repellent layer, an antifogging layer, a control layer, etc. It may be at least one selected from the group consisting of a light layer, an antiglare layer, a sound insulating layer, an antifouling layer, a conductive layer, an antistatic layer, and a protective layer.
More specifically, the functional layer described above includes the first glass layer, the second glass layer, the third glass layer, the fourth glass layer, and the first polycarbonate layer that constitute the multilayer glass of the present invention. , The second polycarbonate layer, the first adhesive layer, the second adhesive layer, the third adhesive layer, and the fourth adhesive layer.
　ただし、このような機能層の機能は、例えば、図３に示した複層ガラス１００’の構成部材自身、すなわち、第１のガラス層１５０、第２のガラス層１５８、第３のガラス層１６０、第４のガラス層１６８、第１のポリカーボネート層１５５、第２のポリカーボネート層１６５、第１の接着層１５２、第２の接着層１５３、第３の接着層１６２、および／または第４の接着層１６３によって代用されても良い。 However, the function of such a functional layer is, for example, the structural member itself of the multi-layer glass 100 ′ shown in FIG. 3, that is, the first glass layer 150, the second glass layer 158, and the third glass layer 160. , Fourth glass layer 168, first polycarbonate layer 155, second polycarbonate layer 165, first adhesive layer 152, second adhesive layer 153, third adhesive layer 162, and / or fourth adhesive. Layer 163 may be substituted.
　（複層ガラス１００の製造方法）
　このような「真空複層ガラス」タイプの複層ガラス１００は、例えば以下のような工程を経て製造される。
　まず、第１の積層体１１５および第２の積層体１２５を準備する。なお、第１の積層体１１５には、間隙部１３５の内部を真空、あるいは減圧にするための吸引用の孔として、第１のガラス層１５０から第２のガラス層１５８まで貫通する微細な貫通孔を一箇所、あるいは数か所に予め形成しておく。 (Manufacturing method of the multi-layer glass 100)
Such a “vacuum double-glazed glass” type double-glazed glass 100 is manufactured through the following processes, for example.
First, the first stacked body 115 and the second stacked body 125 are prepared. Note that the first laminated body 115 has fine through holes penetrating from the first glass layer 150 to the second glass layer 158 as suction holes for making the inside of the gap 135 vacuum or reduced pressure. Holes are formed in advance in one place or several places.
　次に、第１の積層体１１５の第１の表面１１７の外周上に、封止部材１４５用原料（例えばガラスペースト）を形成する。また、第１の積層体１１５の第１の表面１１７に、所定の配置形態で、複数のスペーサ１４０を配置する。 Next, a raw material (for example, glass paste) for the sealing member 145 is formed on the outer periphery of the first surface 117 of the first laminated body 115. In addition, a plurality of spacers 140 are arranged on the first surface 117 of the first stacked body 115 in a predetermined arrangement form.
　次に、スペーサ１４０の上部から、第２の積層体１２５を配置し、組立体を構成する。さらに、この組立体を、最大２５０℃未満の温度で加熱処理して、封止部材１４５用原料を溶融固化させる。これにより、第１の積層体１１５と第２の積層体１２５とが、封止部材１４５によって接合される。 Next, the second laminated body 125 is arranged from the upper part of the spacer 140 to constitute an assembly. Further, this assembly is heat-treated at a temperature lower than a maximum of 250 ° C. to melt and solidify the raw material for the sealing member 145. Thereby, the first stacked body 115 and the second stacked body 125 are joined by the sealing member 145.
　ここで、このような方法で、封止部材を形成する場合、封止部材１４５形成のための加熱処理の温度は、最大でも２５０℃を超えないようにする必要がある。そうでなければ、第１の積層体１１５および第２の積層体１２５に含まれるポリカーボネート層１５５、１６５が軟化、あるいはさらには溶融してしまうためである。 Here, when the sealing member is formed by such a method, it is necessary that the temperature of the heat treatment for forming the sealing member 145 does not exceed 250 ° C. at the maximum. Otherwise, the polycarbonate layers 155 and 165 included in the first stacked body 115 and the second stacked body 125 are softened or further melted.
　次に、第１の積層体１１５に形成しておいた貫通孔に、ガラス管の一端を挿入する。また、ガラス管の他端を吸引装置に結合する。この状態で吸引装置を稼働させ、間隙部１３５内の空気を排気し、間隙部１３５を減圧状態にする。最後に、ガラス管の第１の積層体１１５に挿入された部分を溶融封着することにより、図２に示したような複層ガラス１００が得られる。
　なお、以上の説明は、単なる一例であって、複層ガラス１００は、その他の各種の複層ガラスの製法により製造しても良いことは、当業者には明らかである。 Next, one end of the glass tube is inserted into the through hole formed in the first laminated body 115. Also, the other end of the glass tube is coupled to a suction device. In this state, the suction device is operated, the air in the gap 135 is exhausted, and the gap 135 is decompressed. Finally, by melting and sealing the portion inserted into the first laminated body 115 of the glass tube, the multilayer glass 100 as shown in FIG. 2 is obtained.
Note that the above description is merely an example, and it is obvious to those skilled in the art that the double-glazed glass 100 may be manufactured by various other methods of producing double-glazed glass.
　（本発明による複層ガラスの別の構成）
　図６には、本発明による複層ガラスの別の構成の一例を示す。
　図６に示すように、この複層ガラス２００は、前述の図２に示した複層ガラス１００とほぼ同様の構成を有する。従って、図６において、図２と同様の構成部材には、図２の構成部材の参照符号に１００を加えた参照符号が付されている。 (Another configuration of the multilayer glass according to the present invention)
In FIG. 6, an example of another structure of the multilayer glass by this invention is shown.
As shown in FIG. 6, this double-glazed glass 200 has substantially the same configuration as the double-glazed glass 100 shown in FIG. Accordingly, in FIG. 6, the same reference numerals as those in FIG. 2 are given the reference numerals obtained by adding 100 to the reference numerals of the constituent members in FIG. 2.
　ただし、この図６では、複層ガラス２００は、間隙部２３５に、スペーサを有さない点が、図２の複層ガラス１００とは異なっている。これは、複層ガラス２００は、「真空複層ガラス」ではなく、「不活性ガス充填」タイプの複層ガラスとして構成されるためである。すなわち、複層ガラス２００において、間隙部２３５内は、真空または減圧環境ではなく、不活性ガスが充填された状態にされる。
　なお、不活性ガスの種類としては、例えばアルゴンおよび／またはクリプトン等が挙げられるが、これら以外の不活性ガスを使用しても良い。 However, in FIG. 6, the multilayer glass 200 is different from the multilayer glass 100 of FIG. 2 in that the gap portion 235 does not have a spacer. This is because the multilayer glass 200 is not a “vacuum multilayer glass” but a “inert gas filled” type multilayer glass. That is, in the multilayer glass 200, the gap 235 is not filled with a vacuum or a reduced pressure environment but filled with an inert gas.
In addition, as a kind of inert gas, although argon and / or krypton etc. are mentioned, you may use inert gas other than these, for example.
　このタイプの複層ガラス２００は、前述の「真空複層ガラス」１００に比べると、その断熱性は、低下する。しかしながら、複層ガラス２００では、間隙部２３５に複数のスペーサ１４０を配置したり、間隙部２３５内を真空または減圧処理する必要がなくなる。このため、複層ガラス２００は、複層ガラス１００に比べて、より簡便かつ低コストに作製することができる。 This type of double-glazed glass 200 has a lower heat insulating property than the aforementioned “vacuum double-glazed glass” 100. However, in the multi-layer glass 200, it is not necessary to dispose a plurality of spacers 140 in the gap portion 235 or to vacuum or depressurize the gap portion 235. For this reason, the multilayer glass 200 can be produced more easily and at a lower cost than the multilayer glass 100.
　このような複層ガラス２００の構成においても、第１の積層体２１５および第２の積層体２２５が前述の複層ガラス１００における第１の積層体１１５および第２の積層体１２５と同様の特徴を有する限り、前述のような軽量化および薄肉化の効果が得られることは、明らかである。 Also in such a configuration of the multilayer glass 200, the first laminated body 215 and the second laminated body 225 have the same characteristics as the first laminated body 115 and the second laminated body 125 in the multilayer glass 100 described above. As long as it has, it is clear that the effects of weight reduction and thinning as described above can be obtained.
　（本発明による複層ガラスの適用例）
　本発明による複層ガラス１００、２００は、例えば車両等に適用することができる。
　図７には、本発明による複層ガラス１００、２００が適用され得る車両の一例を示す。図７において、車両４００は、いくつかの透明部材、例えば、フロントウィンドウ部材４１０、サイドウィンドウ部材４２０、ルーフウィンドウ部材４３０、およびリアウィンドウ部材４４０を有する。
　ここで、本発明による複層ガラス１００、２００は、これらの透明部材として使用することができる。 (Application example of the multilayer glass according to the present invention)
The multilayer glass 100, 200 according to the present invention can be applied to, for example, vehicles.
FIG. 7 shows an example of a vehicle to which the multilayer glass 100, 200 according to the present invention can be applied. In FIG. 7, the vehicle 400 includes several transparent members, for example, a front window member 410, a side window member 420, a roof window member 430, and a rear window member 440.
Here, the multilayer glass 100, 200 according to the present invention can be used as these transparent members.
　前述のように、本発明による複層ガラス１００、２００は、第１の積層体および第２の積層体の一部に、ガラスよりも軽量なポリカーボネート層が使用されている。また、本発明による複層ガラス１００、２００では、第１の積層体および第２の積層体の厚さが有意に抑制されている。このため、複層ガラス１００、２００は、厚さが薄く、さらに総重量が有意に低減されている。従って、本発明による複層ガラス１００、２００を車両４００の透明部材として設置しても、透明部材が顕著に出っ張ったり、複層ガラスを支持するための補強部材を別途使用したりする必要性が回避される。また、これにより、重量が上昇して車両の燃費が低下したり、部品点数が増加してしまうと言う問題を軽減することができる。 As described above, the multi-layer glass 100, 200 according to the present invention uses a polycarbonate layer that is lighter than glass in a part of the first laminate and the second laminate. Moreover, in the multilayer glass 100 and 200 by this invention, the thickness of a 1st laminated body and a 2nd laminated body is significantly suppressed. For this reason, the multi-layer glass 100, 200 is thin, and the total weight is significantly reduced. Therefore, even if the multi-layer glass 100, 200 according to the present invention is installed as a transparent member of the vehicle 400, there is a need for the transparent member to protrude remarkably or to separately use a reinforcing member for supporting the multi-layer glass. Avoided. In addition, this can alleviate the problem that the weight increases and the fuel consumption of the vehicle decreases and the number of parts increases.
　このように、本発明による複層ガラス１００、２００は、これまで適用することの難しかった車両４００にも適用することができる。
　また、本発明による複層ガラス１００、２００では、ポリカーボネート層の両側には、ガラス層が配置されており、ポリカーボネート層は、表面が露出されていない。 Thus, the multilayer glass 100, 200 according to the present invention can be applied to the vehicle 400 that has been difficult to apply.
Moreover, in the multilayer glass 100 and 200 by this invention, the glass layer is arrange | positioned at the both sides of the polycarbonate layer, and the surface of the polycarbonate layer is not exposed.
　一般に、ポリカーボネート層は、傷感受性が大きく、他の物との僅かの当接でも容易に傷が生じてしまうという問題がある。この特性は、自動車の透明部材のような、美感および安全性が求められる用途では、軽視することができない問題である。例えば、表面に傷のあるポリカーボネート部材では、周囲光が反射して、運転者が安全な運転を行うことができなくなるおそれがある。 In general, the polycarbonate layer has a high scratch sensitivity, and there is a problem that scratches are easily generated even with slight contact with other objects. This characteristic is a problem that cannot be neglected in applications that require aesthetics and safety, such as automobile transparent members. For example, in a polycarbonate member having a scratch on the surface, ambient light may be reflected, and the driver may not be able to perform safe driving.
　しかしながら、本発明による複層ガラス１００、２００では、ポリカーボネート層の両側に存在するガラス層が、ポリカーボネート層の保護層としての役割を果たすようになる。このため、ポリカーボネート層の表面を、傷や摩耗から保護することができる。また、これにより、車両４００において生じ得る美感および安全性に関する問題にも対処することができる。 However, in the multilayer glass 100, 200 according to the present invention, the glass layers present on both sides of the polycarbonate layer serve as protective layers for the polycarbonate layer. For this reason, the surface of the polycarbonate layer can be protected from scratches and abrasion. Accordingly, it is possible to deal with a problem relating to aesthetics and safety that may occur in the vehicle 400.
　本発明による複層ガラスは、例えば車両の透明部材、および建築物の窓ガラス等に適用することができる。
