FIG. 1 is a plan view of a laminated glass, and FIG. 2 is a cross-sectional view taken along the line AA in FIG. As shown in FIGS. 1 and 2, the laminated glass according to this embodiment includes an outer glass plate 1, an inner glass plate 2, and a resin intermediate film 3 disposed between these glass plates 1 and 2. And. The outer glass plate 1 is laminated with a shielding layer 4 that shields the transmission of light from the outside of the vehicle. Further, a resin frame member 6 is formed on the periphery of the outer glass plate 1. Hereinafter, these will be described.
　＜１－１．外側ガラス板＞
　外側ガラス板１は、水平方向に長い矩形状に形成されている。より詳細には、外側ガラス板１は、水平方向に延びる上辺１１及び下辺１２と、上辺１１及び下辺１２の前端同士を結ぶ前辺１３と、上辺１１及び下辺１２の後端同士を結ぶ後辺１４と、で構成された外形を有している。前辺１３及び後辺１４は下方にいくにしたがってやや後方に延びるように傾斜している。また、下辺１２は、水平な第１部位１２１と、第１部位１２１の後端から後方にいくにしたがって上方に傾斜するように延びる第２部位１２２とを有している。したがって、後辺１４の上端は、前辺１３と同じ高さであるが、下端は前辺１３よりもやや高い位置にあり、全体として前辺１３よりも短く形成されている。 <1-1. Outer glass plate>
The outer glass plate 1 is formed in a rectangular shape that is long in the horizontal direction. More specifically, the outer glass plate 1 includes an upper side 11 and a lower side 12 extending in the horizontal direction, a front side 13 connecting the front ends of the upper side 11 and the lower side 12, and a rear side connecting the rear ends of the upper side 11 and the lower side 12. 14 and an outer shape composed of The front side 13 and the rear side 14 are inclined so as to extend slightly rearward as going downward. The lower side 12 has a horizontal first portion 121 and a second portion 122 extending so as to incline upward from the rear end of the first portion 121 to the rear. Therefore, the upper end of the rear side 14 is the same height as the front side 13, but the lower end is positioned slightly higher than the front side 13 and is formed shorter than the front side 13 as a whole.
　外側ガラス板１は、公知のガラス板を用いることができ、熱線吸収ガラス、一般的なクリアガラスやグリーンガラス、またはＵＶグリーンガラスで形成することもできる。但し、この合わせガラスを自動車の窓ガラスに用いる場合には、自動車が使用される国の安全規格に沿った可視光線透過率を実現する必要がある。例えば、外側ガラス板１により必要な日射吸収率を確保し、内側ガラス板２により可視光線透過率が安全規格を満たすように調整することができる。以下に、クリアガラスの組成の一例と、熱線吸収ガラス組成の一例を示す。 The outer glass plate 1 may be a known glass plate, and may be formed of heat ray absorbing glass, general clear glass, green glass, or UV green glass. However, when this laminated glass is used for a window glass of an automobile, it is necessary to realize visible light transmittance in accordance with the safety standard of the country where the automobile is used. For example, the required solar radiation absorption rate can be secured by the outer glass plate 1, and the visible light transmittance can be adjusted by the inner glass plate 2 so as to satisfy the safety standard. Below, an example of a composition of clear glass and an example of a heat ray absorption glass composition are shown.

The composition can be reduced by an increase of 2 and TiO 2 .
　外側ガラス板１は、主として、外部からの障害に対する耐久性、耐衝撃性が必要であり、小石などの飛来物に対する耐衝撃性能が必要である。この観点から、外側ガラス板１の厚みは、２．３～４．０ｍｍであることが好ましく、２．８～４．０ｍｍであることがさらに好ましく、３．１～４．０ｍｍであることが特に好ましい。 The outer glass plate 1 mainly needs durability and impact resistance against external obstacles, and needs impact resistance against flying objects such as pebbles. From this viewpoint, the thickness of the outer glass plate 1 is preferably 2.3 to 4.0 mm, more preferably 2.8 to 4.0 mm, and 3.1 to 4.0 mm. Particularly preferred.
　また、外側ガラス板１は、風冷強化または化学強化などの強化が施されたものとすることができる。風冷強化が施されると、外側ガラス板１は、一枚でも自動車の安全ガラスとして用いることができる。 Also, the outer glass plate 1 can be subjected to strengthening such as air cooling strengthening or chemical strengthening. When the air-cooling strengthening is performed, the outer glass plate 1 can be used as a safety glass for automobiles.
　また、本実施形態に係る外側ガラス板１の形状は、平面形状及び湾曲形状のいずれであってもよい。ここで、ガラス板が湾曲している場合の厚みの測定方法の一例について説明する。まず、測定位置については、ガラス板の左右方向の中央を上下方向に延びる中央線Ｓ上の上下２箇所である。測定機器は、特には限定されないが、例えば、株式会社テクロック製のＳＭ－１１２のようなシックネスゲージを用いることができる。測定時には、平らな面に外側ガラス板１の湾曲面が載るように配置し、上記シックネスゲージでガラス板の端部を挟持して測定する。なお、外側ガラス板１が平坦な場合でも、湾曲している場合と同様に測定することができる。 Further, the shape of the outer glass plate 1 according to the present embodiment may be either a planar shape or a curved shape. Here, an example of a method for measuring the thickness when the glass plate is curved will be described. First, about a measurement position, it is two places up and down on the center line S extended in the up-down direction at the center of the left-right direction of a glass plate. The measuring instrument is not particularly limited, and for example, a thickness gauge such as SM-112 manufactured by Teclock Co., Ltd. can be used. At the time of measurement, it is arranged so that the curved surface of the outer glass plate 1 is placed on a flat surface, and the end of the glass plate is sandwiched by the thickness gauge and measured. In addition, even when the outer side glass plate 1 is flat, it can measure similarly to the case where it curves.
　＜１－２．遮蔽層＞
　次に、遮蔽層４について説明する。遮蔽層４は、黒などの濃色のセラミックにより形成され、外側ガラス板１の車内側の面に積層されている。以下では、外側ガラス板１において、遮蔽層４が積層されている領域を遮蔽領域ということがある。但し、下辺１２の第１部位１２１の上方には、遮蔽層４が積層されていない矩形状の窓領域５が形成されており、遮蔽層４は、窓領域５を囲む４つの領域４１～４４を有している。すなわち、窓領域５の上側において外側ガラス板１の上辺１１に沿う上側領域４１、窓領域５の前側において外側ガラス板１の前辺１３に沿う前側領域４２、窓領域５の下側において外側ガラス板１の下辺１２の第１部位１２１に沿う下側領域４３、及び窓領域５よりも後方全体に積層された後側領域４４を有しており、これらが一体化されている。 <1-2. Shielding layer>
Next, the shielding layer 4 will be described. The shielding layer 4 is formed of dark ceramic such as black and is laminated on the inner surface of the outer glass plate 1. Below, in the outer side glass plate 1, the area | region where the shielding layer 4 is laminated | stacked may be called a shielding area | region. However, a rectangular window region 5 in which the shielding layer 4 is not laminated is formed above the first portion 121 of the lower side 12, and the shielding layer 4 has four regions 41 to 44 surrounding the window region 5. have. That is, the upper region 41 along the upper side 11 of the outer glass plate 1 on the upper side of the window region 5, the front region 42 along the front side 13 of the outer glass plate 1 on the front side of the window region 5, and the outer glass on the lower side of the window region 5. It has the lower region 43 along the first part 121 of the lower side 12 of the plate 1 and the rear region 44 laminated on the entire rear side of the window region 5, and these are integrated.
　遮蔽層７を構成するセラミックは、例えば、以下の組成とすることができる。

　セラミックは、スクリーン印刷法により形成することができるが、これ以外に、焼成用転写フィルムを外側ガラス板１に転写し焼成することにより作製することも可能である。スクリーン印刷を採用する場合、例えば、ポリエステルスクリーン：３５５メッシュ，コート厚み：２０μｍ，テンション：２０Ｎｍ，スキージ硬度：８０度，取り付け角度：７５°，印刷速度：３００ｍｍ／ｓとすることができ、乾燥炉にて１５０℃、１０分の乾燥により、セラミックを形成することができる。 Ceramic can be formed by a screen printing method, but it can also be produced by transferring a firing transfer film to the outer glass plate 1 and firing. When screen printing is adopted, for example, polyester screen: 355 mesh, coat thickness: 20 μm, tension: 20 Nm, squeegee hardness: 80 degrees, mounting angle: 75 °, printing speed: 300 mm / s, drying oven The ceramic can be formed by drying at 150 ° C. for 10 minutes.
　遮蔽層４は、セラミックを積層するほか、他の材料により形成することもできる。また、濃色の樹脂製の遮蔽フィルムを貼り付けることで形成することもできる。 The shielding layer 4 can be formed of other materials besides laminating ceramics. Moreover, it can also form by sticking the shielding film made from a dark resin.
　＜１－３．枠部材＞
　次に、枠部材６について説明する。枠部材６は、合わせガラスと車体との隙間を埋めるものであり、外側ガラス板１の周縁に沿って形成されている。具体的には、図２に示すように、枠部材６は、外側ガラス板１の周縁を挟むように、断面において、外側ガラス板１の内面に沿う帯状の内側部位６１、外側ガラス板１の外面に沿う帯状の外側部位６２、及びこれら内側部位６１及び外側部位６２を連結するように、外側ガラス板１の端面に沿って延びる連結部位６３を有し、全体としてＵ字型の断面形状を有している。なお、内側部位６１は、遮蔽層４上に配置されている。 <1-3. Frame member>
Next, the frame member 6 will be described. The frame member 6 fills the gap between the laminated glass and the vehicle body, and is formed along the periphery of the outer glass plate 1. Specifically, as shown in FIG. 2, the frame member 6 has a band-shaped inner portion 61 along the inner surface of the outer glass plate 1 in the cross section so as to sandwich the periphery of the outer glass plate 1. It has a strip-shaped outer portion 62 along the outer surface, and a connecting portion 63 extending along the end surface of the outer glass plate 1 so as to connect the inner portion 61 and the outer portion 62, and has a U-shaped cross-sectional shape as a whole. Have. The inner portion 61 is disposed on the shielding layer 4.
　内側部位６１及び外側部位６２の幅は、概ね同じであり、特に、内側部位６１は、窓領域５に達しないように形成されている。すなわち、内側部位６１の内縁は、遮蔽層４の上側領域４１、前側領域４２、下側領域４３及び後側領域４４の内部に位置するように形成されている。 The widths of the inner part 61 and the outer part 62 are substantially the same. In particular, the inner part 61 is formed so as not to reach the window region 5. That is, the inner edge of the inner portion 61 is formed so as to be located inside the upper region 41, the front region 42, the lower region 43, and the rear region 44 of the shielding layer 4.
　そして、この合わせガラスが、車体に取り付けるときには、車体に設けられた開口を塞ぐように、枠部材６の内側部位６１を接着剤によって車体に取り付けることができる。また、接着剤に加え、枠部材６にクリップ（図示省略）を設けておき、これを車体に形成された取付孔（図示省略）に取り付けることもできる。 When the laminated glass is attached to the vehicle body, the inner portion 61 of the frame member 6 can be attached to the vehicle body with an adhesive so as to close the opening provided in the vehicle body. In addition to the adhesive, a clip (not shown) may be provided on the frame member 6 and attached to an attachment hole (not shown) formed in the vehicle body.
　枠部材６を構成する材料は特には限定されないが、例えば、ＴＰＯ（オレフィン系熱可塑性エラストマー）により、射出成形などの公知の方法で形成することができる。その他、例えば、ＰＶＣ（ポリ塩化ビニル）、ＥＰＤＭ（エチレン－プロピレン－ジエン共重合ゴム）によって形成することができる。クリップを設ける場合には、射出成形時に、クリップを外側ガラス板１とともに成形型に配置し、クリップを枠部材６に埋め込むように成形することができる。 Although the material which comprises the frame member 6 is not specifically limited, For example, it can form by well-known methods, such as injection molding, by TPO (olefin type thermoplastic elastomer). In addition, for example, it can be formed of PVC (polyvinyl chloride) or EPDM (ethylene-propylene-diene copolymer rubber). When the clip is provided, the clip can be placed in a mold together with the outer glass plate 1 during injection molding so that the clip is embedded in the frame member 6.
　＜１－４．内側ガラス板＞
　内側ガラス板２は、外側ガラス板１の車内側の面において、窓領域５を覆うように配置される。また、内側ガラス板２は、外側ガラス板１の上辺１１、前辺１３、及び下辺１２の第１部位１２１に、それぞれ沿う上辺２１、前辺２３、及び下辺２２を有し、さらに上辺２１の後端と下辺２２の後端とを結ぶ後辺２４を有している。後辺２４は、外側ガラス板１の下辺１２の第１部位１２１と第２部位１２２との連結部分付近から上方へ延びる第１部位１４１と、第１部位１４１の上端から上方にいくにしたがってやや前方に傾斜する第２部位１４２とを有しており、第２部位１４２の上端が上辺１１の後端に連結されている。 <1-4. Inner glass plate>
The inner glass plate 2 is disposed so as to cover the window region 5 on the inner surface of the outer glass plate 1. Further, the inner glass plate 2 has an upper side 21, a front side 23, and a lower side 22 along the first portion 121 of the upper side 11, the front side 13, and the lower side 12 of the outer glass plate 1, respectively. A rear side 24 connecting the rear end and the rear end of the lower side 22 is provided. The rear side 24 has a first part 141 extending upward from the vicinity of the connection part between the first part 121 and the second part 122 of the lower side 12 of the outer glass plate 1 and slightly increases from the upper end of the first part 141 upward. The second portion 142 is inclined forward, and the upper end of the second portion 142 is connected to the rear end of the upper side 11.
　より詳細に説明すると、内側ガラス板２の上辺２１、前辺２３、及び下辺２２は、遮蔽層４の上側領域４１、前側領域４２、及び下側領域４３にそれぞれ位置しており、これらは、枠部材６よりも内側にある。また、内側ガラス板２の後辺２４は、遮蔽層４の後側領域４４内にあるが、窓領域５の端縁に近い位置にある。したがって、後側領域４４の大半は、内側ガラス板２には覆われず、露出している。 More specifically, the upper side 21, the front side 23, and the lower side 22 of the inner glass plate 2 are located in the upper region 41, the front region 42, and the lower region 43 of the shielding layer 4, respectively. Inside the frame member 6. Further, the rear side 24 of the inner glass plate 2 is in the rear region 44 of the shielding layer 4, but at a position near the edge of the window region 5. Therefore, most of the rear region 44 is not covered by the inner glass plate 2 and is exposed.
　内側ガラス板２は、外側ガラス板１と同様に材料で形成することができる。また、必要に応じて、風冷強化または化学強化を施すことができる。内側ガラス板２の厚みは、合わせガラスの軽量化のため、外側ガラス板１よりも厚みを小さくすることが好ましく、例えば、０．５～１．１ｍｍであることが好ましく、０．５～０．９ｍｍであることがさらに好ましく、０．５～０．７ｍｍであることが特に好ましい。 The inner glass plate 2 can be formed of a material in the same manner as the outer glass plate 1. Moreover, wind cooling reinforcement | strengthening or chemical strengthening can be given as needed. The thickness of the inner glass plate 2 is preferably smaller than the outer glass plate 1 in order to reduce the weight of the laminated glass, and is preferably 0.5 to 1.1 mm, for example, 0.5 to 0 Is more preferably 0.9 mm, and particularly preferably 0.5 to 0.7 mm.
　上記のように、外側ガラス板１が１枚でも安全ガラスとして用いることができる厚みであれば、内側ガラス板２の厚みは外側ガラス板１の厚みの１／２以下とすることができる。 As described above, the thickness of the inner glass plate 2 can be ½ or less of the thickness of the outer glass plate 1 as long as even one outer glass plate 1 can be used as safety glass.
　＜１－５．中間膜＞
　中間膜３は、内側ガラス板２の車外側の面の全面に配置される樹脂製の膜である。一例として、図２の拡大図に示すように、軟質のコア層３１を、これよりも硬質のアウター層３２で挟持した３層で構成することができる。但し、この構成に限定されるものではなく、軟質のコア層３１を有する複数層で形成されていればよい。例えば、コア層３１を含む２層（コア層が１層と、アウター層が１層）、またはコア層３１を中心に配置した５層以上の奇数の層（コア層が１層と、アウター層が４層）、あるいはコア層３１を内側に含む偶数の層（コア層が１層と、他の層がアウター層）で形成することもできる。あるいは、一層で中間膜３を構成することもできる。 <1-5. Interlayer>
The intermediate film 3 is a resin film disposed on the entire surface of the inner glass plate 2 on the vehicle outer side. As an example, as shown in the enlarged view of FIG. 2, the soft core layer 31 can be composed of three layers sandwiched by a harder outer layer 32 than this. However, it is not limited to this configuration, and it may be formed of a plurality of layers having the soft core layer 31. For example, two layers including the core layer 31 (one core layer and one outer layer), or an odd number of five or more layers arranged around the core layer 31 (one core layer and one outer layer) 4 layers), or an even number of layers including the core layer 31 inside (the core layer is one layer and the other layers are outer layers). Alternatively, the intermediate film 3 can be formed of a single layer.
　コア層３１はアウター層３２よりも軟質の材料により形成することができるが、これに限定されない。また、各層３１，３２を構成する材料は、特には限定されないが、例えば、コア層が軟質となるような材料で形成することができる。例えば、アウター層３２は、ポリビニルブチラール樹脂（ＰＶＢ）によって構成することができる。ポリビニルブチラール樹脂は、各ガラス板との接着性や耐貫通性に優れるので好ましい。一方、コア層３１は、エチレンビニルアセテート樹脂（ＥＶＡ）、またはアウター層３２を構成するポリビニルブチラール樹脂よりも軟質なポリビニルアセタール樹脂によって構成することができる。軟質なコア層３１を間に挟むことにより、単層の樹脂中間膜３と同等の接着性や耐貫通性を保持しながら、遮音性能を大きく向上させることができる。 The core layer 31 can be formed of a softer material than the outer layer 32, but is not limited thereto. Moreover, although the material which comprises each layer 31 and 32 is not specifically limited, For example, it can form with a material in which a core layer becomes soft. For example, the outer layer 32 can be comprised by polyvinyl butyral resin (PVB). Polyvinyl butyral resin is preferable because it is excellent in adhesiveness and penetration resistance with each glass plate. On the other hand, the core layer 31 can be made of an ethylene vinyl acetate resin (EVA) or a polyvinyl acetal resin that is softer than the polyvinyl butyral resin that forms the outer layer 32. By sandwiching the soft core layer 31 between them, the sound insulation performance can be greatly improved while maintaining the same adhesion and penetration resistance as the single-layer resin intermediate film 3.
　ところで、上記のように、剛性の低いコア層３１を、剛性の高い一対のアウター層３２で挟むように構成すると、次のような遮音効果を得ることができる。例えば、周波数１００Ｈｚ，温度２０℃において、ヤング率が１～２０ＭＰａのコア層３１を配置し、アウター層をこれよりもヤング率が高い材料で形成する。 By the way, as described above, when the core layer 31 having low rigidity is sandwiched between the pair of outer layers 32 having high rigidity, the following sound insulation effect can be obtained. For example, the core layer 31 having a Young's modulus of 1 to 20 MPa is disposed at a frequency of 100 Hz and a temperature of 20 ° C., and the outer layer is formed of a material having a higher Young's modulus.
　一般的に、ガラス板の厚みは小さいほど、音響透過損失が低下するコインシデンス周波数が高くなることが知られている。例えば、２ｍｍのガラス板は５０００Ｈｚあたりにコインシデンス周波数が存在し、１ｍｍのガラス板は８０００Ｈｚにコインシデンス周波数が存在する。ここで、中間膜の剛性が高いと、１ｍｍのガラス板と２ｍｍのガラス板との合わせガラスでは、これらが一体化した３ｍｍの単板のような遮音性能を示す。すなわち、剛性が高い中間膜を有する合計厚みが３ｍｍの合わせガラスは、コインシデンス周波数がより低くなり、４０００Ｈｚ付近にコインシデンス周波数が存在することになる。 Generally, it is known that the coincidence frequency at which the sound transmission loss is reduced increases as the thickness of the glass plate decreases. For example, a 2 mm glass plate has a coincidence frequency around 5000 Hz, and a 1 mm glass plate has a coincidence frequency at 8000 Hz. Here, when the rigidity of the intermediate film is high, the laminated glass of the 1 mm glass plate and the 2 mm glass plate exhibits sound insulation performance like a 3 mm single plate in which these are integrated. That is, a laminated glass having a total thickness of 3 mm having an intermediate film having high rigidity has a lower coincidence frequency, and a coincidence frequency exists in the vicinity of 4000 Hz.
　一方、中間膜の剛性が低い場合には、例えば、１ｍｍの単板と２ｍｍの単板との合わせガラスは、２枚のガラス板を合算したような遮音性能を示す。すなわち、この場合には、２ｍｍのガラス板のコインシデンス周波数と、１ｍｍのガラス板のコインシデンス周波数の間、つまり５０００～８０００Ｈｚの間にコインシデンス周波数が存在することになる。したがって、人間が聞き取りやすい２０００～５０００Ｈｚの周波数域での遮音性能の低下を防止することができる。このような観点から、上記のように、中間膜３の中に剛性の低いコア層３１を設ければ、遮音性能を向上することができる。 On the other hand, when the rigidity of the interlayer film is low, for example, a laminated glass of a 1 mm single plate and a 2 mm single plate exhibits a sound insulation performance as if two glass plates were added together. That is, in this case, there is a coincidence frequency between the coincidence frequency of the 2 mm glass plate and the coincidence frequency of the 1 mm glass plate, that is, between 5000 and 8000 Hz. Accordingly, it is possible to prevent a decrease in sound insulation performance in a frequency range of 2000 to 5000 Hz that is easy for humans to hear. From such a viewpoint, if the core layer 31 having low rigidity is provided in the intermediate film 3 as described above, the sound insulation performance can be improved.
　中間膜３の総厚は、特に規定されないが、０．３～６．０ｍｍであることが好ましく、０．５～４．０ｍｍであることがさらに好ましく、０．６～２．０ｍｍであることが特に好ましい。一方、コア層３１の厚みは、０．１～２．０ｍｍであることが好ましく、０．１～０．６ｍｍであることがさらに好ましい。０．１ｍｍよりも小さくなると、軟質なコア層３１の影響が及びにくくなり、また、２．０ｍｍや０．６ｍｍより大きくなると総厚があがりコストアップとなるからである。一方、アウター層３２の厚みは特に限定されないが、例えば、０．１～２．０ｍｍであることが好ましく、０．１～１．０ｍｍであることがさらに好ましい。その他、中間膜３の総厚を一定とし、この中でコア層１３１の厚みを調整することもできる。 The total thickness of the intermediate film 3 is not particularly limited, but is preferably 0.3 to 6.0 mm, more preferably 0.5 to 4.0 mm, and 0.6 to 2.0 mm. Is particularly preferred. On the other hand, the thickness of the core layer 31 is preferably 0.1 to 2.0 mm, and more preferably 0.1 to 0.6 mm. This is because if the thickness is smaller than 0.1 mm, the influence of the soft core layer 31 is difficult to reach, and if the thickness is larger than 2.0 mm or 0.6 mm, the total thickness increases and the cost is increased. On the other hand, the thickness of the outer layer 32 is not particularly limited, but is preferably 0.1 to 2.0 mm, and more preferably 0.1 to 1.0 mm. In addition, the total thickness of the intermediate film 3 can be made constant, and the thickness of the core layer 131 can be adjusted therein.
　中間膜３の製造方法は特には限定されないが、例えば、上述したポリビニルアセタール樹脂等の樹脂成分、可塑剤及び必要に応じて他の添加剤を配合し、均一に混練りした後、各層を一括で押出し成型する方法、この方法により作成した２つ以上の樹脂膜をプレス法、ラミネート法等により積層する方法が挙げられる。プレス法、ラミネート法等により積層する方法に用いる積層前の樹脂膜は単層構造でも多層構造でもよい。 Although the manufacturing method of the intermediate film 3 is not particularly limited, for example, the resin component such as the above-mentioned polyvinyl acetal resin, a plasticizer, and other additives as necessary are blended and uniformly kneaded, and then each layer is collectively And a method of laminating two or more resin films prepared by this method by a pressing method, a laminating method or the like. The resin film before lamination used in a method of lamination by a press method, a lamination method, or the like may have a single layer structure or a multilayer structure.
　＜２．合わせガラスの製造方法＞
　本実施形態に係る合わせガラスの製造方法は、特に限定されず、従来より公知の合わせガラスの製造方法を採用することができる。まず、上記のように、所定の形状に形成された外側ガラス板１に遮蔽層４を積層する。続いて、外側ガラス板１が湾曲するように曲げ加工を行う。この方法は、特には限定されないが、例えば、公知のプレス成形により行うことができる。あるいは、成形型上に外側ガラス板１を配置した後、この成形型を加熱炉を通過させて加熱する。これによって、外側ガラス板１を自重により湾曲させることができる。そして、外側ガラス板１が湾曲した後、風冷強化を施す。その後、上記のように、枠部材６を成形すれば、外側ガラス板１が完成する。 <2. Manufacturing method of laminated glass>
The manufacturing method of the laminated glass which concerns on this embodiment is not specifically limited, The manufacturing method of a conventionally well-known laminated glass can be employ | adopted. First, as described above, the shielding layer 4 is laminated on the outer glass plate 1 formed in a predetermined shape. Subsequently, bending is performed so that the outer glass plate 1 is curved. Although this method is not specifically limited, For example, it can carry out by well-known press molding. Or after arrange | positioning the outer side glass plate 1 on a shaping | molding die, this shaping | molding die is passed through a heating furnace and heated. As a result, the outer glass plate 1 can be bent by its own weight. And after the outer side glass plate 1 curves, air cooling reinforcement | strengthening is given. Then, if the frame member 6 is shape | molded as mentioned above, the outer side glass plate 1 will be completed.
　次に、内側ガラス板２を製造する。まず、所定の形状に形成された内側ガラス板２に対し、プレス成形あるいは自重による曲げ成形により湾曲した形状を形成する。その後、必要に応じて、化学強化を施せば、内側ガラス板２が完成する。但し、曲げ加工を行わず、化学強化のみを施して内側ガラス板２を完成させることもできる。これは、外側ガラス板１は湾曲しているものの、サイドガラスでは、曲率半径が大きいため、薄い内側ガラス板２であれば、個別に曲げ加工を行わなくても、後述するように、外側ガラス板１に接着することで、外側ガラス板１の湾曲に沿わせることができるからである。 Next, the inner glass plate 2 is manufactured. First, a curved shape is formed on the inner glass plate 2 formed in a predetermined shape by press molding or bending by its own weight. Thereafter, if necessary, the inner glass plate 2 is completed by chemical strengthening. However, the inner glass plate 2 can be completed by performing only chemical strengthening without bending. This is because although the outer glass plate 1 is curved, the side glass has a large radius of curvature. Therefore, if the inner glass plate 2 is thin, the outer glass plate 2 will be described later without performing individual bending. It is because it can be made to follow the curve of the outer side glass plate 1 by adhere | attaching on 1. FIG.
　次に、中間膜３を外側ガラス板１及び内側ガラス板２の間に挟み、これをゴムバッグに入れ、減圧吸引しながら約７０～１１０℃で予備接着する。このとき、中間膜３は、内側ガラス板２と同じ形状か、あるいはやや大きい形状とすることができる。予備接着は、これ以外の方法を用いることもできる。例えば、中間膜３を外側ガラス板１及び内側ガラス板２の間に挟み、オーブンにより４５～６５℃で加熱する。続いて、この合わせガラスを０．４５～０．５５ＭＰａでロールにより押圧する。次に、この合わせガラスを、再度オーブンにより８０～１０５℃で加熱した後、０．４５～０．５５ＭＰａでロールにより再度押圧する。こうして、予備接着が完了する。 Next, the intermediate film 3 is sandwiched between the outer glass plate 1 and the inner glass plate 2, put into a rubber bag, and pre-bonded at about 70 to 110 ° C. while sucking under reduced pressure. At this time, the intermediate film 3 can have the same shape as the inner glass plate 2 or a slightly larger shape. Other methods can be used for the preliminary bonding. For example, the intermediate film 3 is sandwiched between the outer glass plate 1 and the inner glass plate 2 and heated at 45 to 65 ° C. in an oven. Subsequently, this laminated glass is pressed by a roll at 0.45 to 0.55 MPa. Next, the laminated glass is again heated at 80 to 105 ° C. in an oven and then pressed again with a roll at 0.45 to 0.55 MPa. Thus, preliminary bonding is completed.
　次に、本接着を行う。予備接着がなされた合わせガラスを、オートクレーブにより、８～１５気圧で、１００～１５０℃によって、本接着を行う。具体的には、１４気圧で１４５℃の条件で本接着を行うことができる。こうして、本実施形態に係る合わせガラスが完成する。 Next, this bonding is performed. The pre-bonded laminated glass is subjected to main bonding by an autoclave at 8 to 15 atm and 100 to 150 ° C. Specifically, the main bonding can be performed under the conditions of 14 atm and 145 ° C. Thus, the laminated glass according to this embodiment is completed.
　なお、枠部材６は、オートクレーブの後に取り付けることもできる。すなわち、強化した外側ガラス板１と、強化した内側ガラス板２とを、上記のように中間膜２を介して接着した後、外側ガラス板１の周縁に枠部材３を、上述したような成形により取り付けることができる。 The frame member 6 can be attached after the autoclave. That is, after the strengthened outer glass plate 1 and the strengthened inner glass plate 2 are bonded via the intermediate film 2 as described above, the frame member 3 is formed on the periphery of the outer glass plate 1 as described above. Can be attached.
　以上のようにして製造された合わせガラスは、上記のように枠部材６を車体に接着することで車体に取り付けられる。したがって、外側ガラス板１の概ね全体が車外に露出する。一方、車内には内装パネル（図示省略）が取り付けられ、内側ガラス板２のみが車内に露出するように構成することができる。このとき、内装パネルは、内側ガラス板２の周縁部を隠すように配置することができる。したがって、内側ガラス板２の周縁部を除いた部分のみが車内に露出し、その他の部分は内装パネルの内部（自動車のボディの内部）に収容される。 The laminated glass manufactured as described above is attached to the vehicle body by adhering the frame member 6 to the vehicle body as described above. Therefore, almost the entire outer glass plate 1 is exposed outside the vehicle. On the other hand, an interior panel (not shown) can be attached in the vehicle, and only the inner glass plate 2 can be exposed in the vehicle. At this time, the interior panel can be arranged so as to hide the peripheral edge portion of the inner glass plate 2. Therefore, only the part except the peripheral edge part of the inner side glass plate 2 is exposed in the vehicle, and the other part is accommodated in the interior panel (inside the body of the automobile).
　＜３．特徴＞
　以上のように、本実施形態によれば、内側ガラス板２が外側ガラス板１よりも小さいため、合わせガラスの軽量化を図ることができる。 <3. Features>
As mentioned above, according to this embodiment, since the inner side glass plate 2 is smaller than the outer side glass plate 1, the weight reduction of a laminated glass can be achieved.
　また、従来、サイドガラスとして用いられた単板のガラス板を、外側ガラス板１として利用し、これに中間膜３と内側ガラス板２を取り付ければ、本実施形態に係る合わせガラスを得ることができる。したがって、例えば、従来のサイドガラスに高い遮音性能を付与したい場合には、上記のように、中間膜３及び内側ガラス板２を取り付ければよい。これにより、高い遮音性能を付与したい場合には、上記のように合わせガラスを形成し、高い遮音性能が不要である場合には、内側ガラス板２及び中間膜３を取り付けず、外側ガラス板１だけでサイドガラスを構成することができる。したがって、用途に応じたサイドガラスの製造が容易になる。また、外側ガラス板１のみ、及び合わせガラスの両方の在庫を有する必要がないため、生産コストの観点からも有利である。 Conventionally, if a single glass plate used as a side glass is used as the outer glass plate 1 and the intermediate film 3 and the inner glass plate 2 are attached thereto, the laminated glass according to the present embodiment can be obtained. . Therefore, for example, when it is desired to impart high sound insulation performance to the conventional side glass, the intermediate film 3 and the inner glass plate 2 may be attached as described above. As a result, when high sound insulation performance is desired, laminated glass is formed as described above, and when high sound insulation performance is unnecessary, the inner glass plate 2 and the intermediate film 3 are not attached, and the outer glass plate 1 is attached. A side glass can be constituted only by this. Therefore, it becomes easy to manufacture the side glass according to the application. Moreover, since it is not necessary to have the stock of both the outer glass plate 1 and the laminated glass, it is advantageous from the viewpoint of production cost.
　枠部材３は、射出成形などで形成されているが、本実施形態では、外側ガラス板１にのみ取り付けられており、内側ガラス板２と枠部材６とが接触しないようになっている。これは、内側ガラス板２は、外側ガラス板１に比べて薄いため、内側ガラス板２にも枠部材６を取り付けると成形時に割れが生じるおそれがあることによる。但し、内側ガラス板２の厚みによっては、枠部材６が内側ガラス板２にも接するように取り付けることもできる。 Although the frame member 3 is formed by injection molding or the like, in this embodiment, it is attached only to the outer glass plate 1 so that the inner glass plate 2 and the frame member 6 do not come into contact with each other. This is because the inner glass plate 2 is thinner than the outer glass plate 1, so that if the frame member 6 is attached to the inner glass plate 2, cracking may occur during molding. However, depending on the thickness of the inner glass plate 2, the frame member 6 can also be attached so as to contact the inner glass plate 2.
　＜４．変形例＞

Since the rear region 44 of the shielding layer 4 is hidden by the interior panel, a glass antenna can be disposed in this portion. However, even in the case where the shielding layer 4 is not provided, a glass antenna is disposed in a portion of the outer glass plate 1 where the inner glass plate 2 is not disposed and hidden in the body of the automobile such as an interior panel. Can do.
　＜４－４＞
　上記実施形態では、従来のサイドガラスを外側ガラス板１とする例を示したが、本発明に係る合わせガラス用の外側ガラス板１を準備し、これに中間膜３及び内側ガラス板２を取り付けることもできる。すなわち、厚みが薄かったり、強化が施されていない外側ガラス板１だけでは、安全ガラスとして用いることができない場合でも、これに中間膜３及び内側ガラス板２を取り付けることで、合わせガラスを形成すれば、サイドガラス、リアガラス、ウインドシールドとして用いることができる。 <4-4>

You can also. That is, even if the outer glass plate 1 that is thin or not tempered alone cannot be used as safety glass, the laminated glass can be formed by attaching the intermediate film 3 and the inner glass plate 2 thereto. For example, it can be used as side glass, rear glass, and windshield.
