Description
前記中間膜の外周端は、前記合わせガラスの少なくとも一部において、前記一対のガラス板の2枚のガラス板の外周端よりも内側に存在することを特徴とする合わせガラスを提供する。
ここで、Dは、中間膜4の外周端と一対のガラス板の2枚のガラス板の外周端との距離、すなわち第1ガラス板2のはみ出し長さまたは第2ガラス板3のはみ出し長さ(以下、はみ出し長さDともいう)を表し、第1ガラス板2のはみ出し長さと第2ガラス板3のはみ出し長さとが異なる場合には、短い方の長さを指す。
また、Eは、第1ガラス板2の外周端と第2ガラス板3の外周端との距離(以下、板ずれ幅Eともいう)を示す。
合わせガラス1が車両用に用いられる場合、第1ガラス板2が車内側に配置され、第2ガラス板3が車外側に配置される。合わせガラス1が建築用に用いられる場合、第1ガラス板2が室内側に配置され、第2ガラス板3が室外側に配置される。
本発明の合わせガラス1は、一対のガラス板と、一対のガラス板の間に設けられた中間膜4と、が積層され、中間膜4のせん断貯蔵弾性率G’が2~100MPaである合わせガラスである。さらに、中間膜4の外周端は、合わせガラス1の外周端の少なくとも一部において、一対のガラス板の2枚のガラス板の外周端よりも内側に存在する。
上記の構成を有する本発明の合わせガラス1は、エッジ発泡耐性に優れる。その理由については明らかでないが、以下のように推測している。
なお、本明細書において、「上辺部」及び「下辺部」とは、合わせガラスを車両に取り付けたときに上側及び下側になる辺を意味し、「側辺部」とは他の2辺を意味する。また、「上辺部」は、合わせガラスの上辺近傍の領域を、「下辺部」は、合わせガラスの下辺近傍の領域をそれぞれ意味する。
一対のガラス板である第1ガラス板2及び第2ガラス板3としては、白色系ソーダライムガラス、グリーン系有色ソーダライムガラス、紫外線遮蔽性有色ソーダライムガラス、熱線吸収性有色ソーダライムガラス、化学強化されたアルミノシリケートガラス等が使用できる。熱線吸収性有色ソーダライムガラスは、白色系ガラスの組成から、全酸化鉄の含有比率、TiO2の含有比率、CeO2の含有比率を増加させた組成を有する。Fe2O3に換算した全鉄量が0.5~1.0質量%であることが好ましい。これにより、合わせガラス1の遮熱性に優れ、かつ安全上必要な可視光透過率が得られる。また、全鉄量に占める2価の酸化鉄の比率(レドックスともいう)が20~30質量%であることが好ましく、22~27質量%であることがより好ましく、24~25質量%であることがさらに好ましい。
中間膜4は、せん断貯蔵弾性率G’が2~100MPaである。前記せん断貯蔵弾性率G’は、温度20℃、周波数1Hz及び歪0.05%の測定条件下、一般的な動的粘弾性測定方法により測定した値である。
上記有機エステル可塑剤は、ジ-(2-ブトキシエチル)-アジペート(以下、DBEAともいう)、トリエチレングリコールジ-2-エチルヘキサノエート(以下、3GOともいう)、トリエチレングリコールジ-2-エチルブチレート(以下、3GHともいう)又はトリエチレングリコールジ-2-エチルプロパノエートを含むことが好ましく、なかでも、3GO、3GH又はトリエチレングリコールジ-2-エチルプロパノエートを含むことがより好ましく、3GO又はトリエチレングリコールジ-2-エチルブチレートを含むことが更に好ましく、トリエチレングリコールジ-2-エチルヘキサノエートを含むことが特に好ましい。
上記可塑剤としては、2種類以上を併用してもよい。
第2の樹脂層のせん断貯蔵弾性率G’は、0.3~1.0MPaであることが好ましく、0.3~0.7MPaであることがより好ましく、0.3~0.5MPaであることがさらに好ましい。上記範囲内であると、合わせガラス1の遮音性がよい。
第2の樹脂層のヤング率は、1~25MPaであることが好ましい。上記範囲内であると、合わせガラス1の衝撃耐性及び遮音性を確保することができる。
第1の樹脂層及び第3の樹脂層のヤング率は、210~1700MPaであることが好ましい。上記範囲内であると、外力に対する衝撃耐性と加工性とを確保することができる。
合わせガラス1は、公知の技術により製造できる。
一対のガラス板の間に中間膜を挿入した、合わせガラス前駆体を準備する。この合わせガラス前駆体をゴムバッグのような真空バッグの中に入れ、真空バッグ内の圧力が約-65~-100kPaの減圧度となるように減圧吸引しながら、約70~110℃で接着することにより、合わせガラス1を得ることができる。次いで、100~140℃、圧力0.6~1.3MPaの条件で加熱加圧する圧着処理を行うことにより、より耐久性に優れた合わせガラス1を得ることができる。
合わせガラス1は、車両用合わせガラス、建築用合わせガラスとして使用できる。車両用合わせガラスは、サイドガラスに限定されず、フロントガラス又はリアガラスにも使用できるが、サイドガラスであることが好ましい。
第1の樹脂層を形成するための組成物と、第2の樹脂層を形成するための組成物と、第3の樹脂層を形成するための組成物とを、共押出機を用いて共押し出しすることにより、第1の樹脂層、第2の樹脂層及び第3の樹脂層がこの順に積層されてなる積層構造を含む中間膜Aを、表2の構成に従い、作製した。第1の樹脂層、第2の樹脂層、第3の樹脂層として、いずれもポリビニルブチラール(PVB)を用いた。可塑剤としては、トリエチレングリコールジ-2-エチルヘキサノエート(3GO)を用いた。
中間膜を表1及び表2に記載の構成とし、第1ガラス板および第2ガラス板の材料または板厚を変更し、合わせガラスを表1に記載の構成とした以外は、実施例1と同様の方法で、合わせガラスを作製した。
合わせガラスを図2の部分断面図にみられるように縦に切断し、切断面をマイクロスコープ(VHX-5000、キーエンス社製)で撮影した。第1ガラス板の最先端部を通り、板厚方向に平行な直線と、中間膜の最先端部を通り、該直線と平行な直線との最短距離と、第2ガラス板の最先端部を通り、板厚方向に平行な直線と、中間膜4の最先端部を通り、該直線と平行な直線との最短距離とを測定し、短い方の距離をはみ出し長さDとした。結果を表1に示す。
合わせガラスを図2の部分断面図にみられるように縦に切断し、切断面をマイクロスコープ(VHX-5000、キーエンス社製)で撮影した。第1ガラス板の最先端部を通り、板厚方向に平行な直線と、第2ガラス板の最先端部を通り、板厚方向に平行な直線との最短距離とを測定し、板ずれ幅Eとした。結果を表1に示す。
第1ガラス板及び第2ガラス板について、紫外・可視・近赤外分光光度計(Solid Spec-3700、島津製作所社製)を用いて、紫外線透過率Tuv及び日射透過率Teを測定した。合わせガラスについて、日射透過率Teを測定した。結果を表1に示す。
中間膜について、温度20℃、周波数1Hz及び歪0.05%の測定条件下で、レオメータ(MCR301、アントンパール社製)を用いてせん断貯蔵弾性率G’を測定した。結果を表1に示す。
端部から内側に5mmの位置において、主面に対し垂直な面かつ側面に対して平行な方向に切断した、幅1cmの中間膜をTHFに溶解し、測定用サンプルを得た。一方、濃度が既知の可塑剤溶液を数点準備した。濃度が既知の可塑剤溶液をGPC測定し、可塑剤量とピーク面積とが相関した近似曲線を得た。次に、予め得た該近似曲線から、測定サンプルの端部に含まれる可塑剤量[mg]を求め、中間膜主面における単位面積あたりの可塑剤量[mg/mm2]とした。結果を表1に示す。
幅100mm×長さ300mmに切断した合わせガラスについて、圧縮引張試験機を用いて、温度23℃、スパン200mmの測定条件下、変位速度毎分1mmにて変位を加えたときの、荷重と変位の比率[N/mm]を三点曲げ剛性として測定した。結果を表3に示す。
合わせガラスについて、サンシャインカーボンアーク灯式耐候性試験機(スガ試験機社製、S80)を用いて、ブラックパネル温度83℃、降雨なしの条件下、太陽模擬光線を照射した。照射後に、合わせガラスの前出の上辺部の外観を目視で確認した。中間膜端部に、5000時間照射後に発泡がなかった場合は◎、3000時間照射後に発泡ないが5000時間照射後に長径0mm超1mm以下の発泡があった場合は○、3000時間照射後に発泡ないが5000時間照射後に長径1mm超の発泡があった場合は△、3000時間照射後に長径1mm超の発泡があった場合は×とした。結果を表3に示す。
合わせガラスの外観について、目視にて評価した。端部が目立たない場合は○、端部が目立つ場合は×とした。結果を表3に示す。
SAE J1400に準拠して、20℃にて合わせガラスの音響透過損失(STL)を測定した。結果を表3に示す。
