Description
[複層構造体]
図1は、第1実施形態に係る複層構造体を例示する断面図である。図1に示すように、複層構造体10は、樹脂層11と、接着剤層12と、ガラス層13と、接着剤層14とを有している。複層構造体10において、ガラス層13は、樹脂層11上に接着剤層12を介して積層されている。又、樹脂層11の接着剤層12が積層されている側とは反対側の面には、接着剤層14が形成されている。
樹脂層11は、ガラス層13等を積層する基材となる層であり、可撓性を有する。樹脂層11は、一つ又は複数の層から構成されている。樹脂層11が複数層からなる場合には、接着機能を有する密着層を介在させ積層させることが好ましい。樹脂層11の総厚みは、可撓性の観点から20μm以上1000μm以下であればよく、好ましくは25μm以上500μm以下、より好ましくは25μm以上300μm以下の範囲である。
接着剤層12としては、任意の適切な接着剤が用いられる。接着剤層12の厚みは、うねりの観点から、0.5μm以上25μm以下であることが好ましく、0.5μm以上5μm以下であることがより好ましく、0.5μm以上3μm以下であることが更に好ましい。
ガラス層13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13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。
樹脂層11、接着剤層12、ガラス層13の積層部は、例えば、プレス加工等により所定の形状に形成した樹脂層11とガラス層13とを接着剤層12を介して積層させることで得られる。或いは、樹脂層11とガラス層13とを接着剤層12を介してロールトゥロールプロセスを利用して連続的に積層後、プレス加工等により、任意のサイズに個片化してもよい。
複層構造体10は、例えば、建築物の壁面や家具や家電の表面に光沢を持たせる部材、保護フィルム、化粧板、パーテーション等に用いられる。以降に例示する複層構造体についても同様である。
第1実施形態の変形例では、第1実施形態とは層構造の異なる複層構造体の例を示す。なお、第1実施形態の変形例において、既に説明した実施形態と同一構成部についての説明は省略する場合がある。
