Abstract
Description
図1は、本実施形態に係る複層構造体を例示する斜視図である。図1に示すように、複層構造体10は、ガラス層11と樹脂層12が交互に複数層配置された構造である。
ガラス層11は、特に限定はなく、目的に応じて適切なものを採用できる。ガラス層11は、組成による分類によれば、例えば、ソーダ石灰ガラス、ホウ酸ガラス、アルミノ珪酸ガラス、石英ガラス等が挙げられる。又、アルカリ成分による分類によれば、無アルカリガラス、低アルカリガラスが挙げられる。上記ガラスのアルカリ金属成分(例えば、Na2O、K2O、Li2O)の含有量は、好ましくは15重量%以下であり、更に好ましくは10重量%以下である。
本願において、樹脂層は、樹脂成分を含む層を指す。樹脂層は、樹脂層を形成するための無機粒子等の添加剤を含んでいてもよい。具体的には、接着層、粘着層又は中間膜のみで構成される層は樹脂層に該当する。図5(a)は、樹脂層12が接着層、粘着層又は中間膜のみで構成される例である。
可撓性の樹脂基材としては、例えば、ポリエーテルサルホン系樹脂;ポリカーボネート系樹脂;アクリル系樹脂;ポリエチレンテレフタレート系樹脂、ポリエチレンナフタレート系樹脂等のポリエステル系樹脂;ポリオレフィン系樹脂;ノルボルネン系樹脂等のシクロオレフィン系樹脂;ポリイミド系樹脂;ポリアミド系樹脂;ポリイミドアミド系樹脂;ポリアリレート系樹脂;ポリサルホン系樹脂;ポリエーテルイミド系樹脂等が挙げられる。中でもポリエチレンテレフタレート、ポリカーボネート、ポリオレフィンを使用することが好ましい。樹脂基材の色は特に限定しないが、透明性の観点から不透明なものは好まれない。樹脂フィルムの厚みは25μm~1mm程度が好ましく。特に好ましくは50μm~500μmである。
接着剤若しくは粘着剤としては、任意の適切な接着剤若しくは粘着剤が用いられる。具体的には、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、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が挙げられる。
(樹脂層12が接着層、粘着層、又は中間膜のみで構成される場合)
図6は、樹脂層が接着層のみで構成される場合の複層構造体の製造方法を例示する図である。樹脂層12が接着層のみで構成される場合は、例えば、図6に示す方法により、複層構造体10Bを製造できる。樹脂層12が粘着層又は中間膜のみで構成される場合も、図6と同様の方法により、複層構造体10Bを製造できる。
図7は、樹脂層が樹脂フィルムと接着層で構成される場合の複層構造体の製造方法を例示する図である。樹脂層12が樹脂フィルムと接着層で構成される場合は、例えば、図7に示す方法により、複層構造体10Bを製造できる。樹脂層12が樹脂フィルムと粘着層で構成される場合も、図7と同様の方法により、複層構造体10Bを製造できる。
本実施形態に係る複層構造体は、例えば、工業用の配管、建築資材、ショーケース、曲面窓等に使用することができる。
