Abstract
Description
1つの実施形態においては、上記脆性フィルムの厚みが、20μm〜300μmである。
1つの実施形態においては、上記気体吹き付け時の気圧が、0.01MPa〜1MPaである。
1つの実施形態においては、気体噴射口を備える気体噴射装置により、上記気体の吹き付けが行われ、該気体噴射口と、上記脆性フィルムとの距離が、1mm〜500mmである。
1つの実施形態においては、上記靭性フィルムの幅が、上記脆性フィルムの幅に対して、1%〜110%である。
1つの実施形態においては、上記靭性フィルムの脆性フィルムに対する接着力が、0.005N/25mm〜10N/25mmである。
1つの実施形態においては、上記フィルム積層体の製造方法は、上記長尺状の靭性フィルムを送り出し、該靭性フィルムと上記脆性フィルムとを貼り合せる前に、該靭性フィルムおよび/または該脆性フィルム上に接着剤を塗布することを含む。
1つの実施形態においては、上記靭性フィルムが接着層付き靭性フィルムとして、上記フィルム積層体の製造方法に供され、長尺状の該靭性フィルムを送り出し、該靭性フィルム上に接着剤を塗布して接着層付き靭性フィルムを形成し、その後、該接着層付き靭性フィルムを巻き取らず、連続的に、靭性フィルムと脆性フィルムとの貼り合せを行う。
1つの実施形態においては、上記脆性フィルムの上記靭性フィルムとは反対側に、支持ロールまたは支持台を配置し、該支持ロールまたは支持台上で、気体の吹き付けを行う。
長尺状のガラスフィルム(厚み:100μm、幅:500mm、破壊靭性値:0.7MPa/m1/2)を、支持ロール上で水平方向に搬送させながら、該ガラスフィルムの上方から、ガラスフィルムに接着層付き靭性フィルムの接着層側を近づけて接触させ、接触点において、接着層付き靭性フィルムの上方(靭性フィルム側)から気体を吹き付けた。なお、接着層付き靭性フィルムは、PET(厚み:100μm、幅25mm、破壊靭性値:3MPa/m1/2)から形成される靭性フィルムと接着層(厚み:5μm)とから構成される。接着層はガラスフィルムと靭性フィルムとを接触させる直前に、靭性フィルムにエポキシ系接着剤を塗布して形成した。また、気圧は0.4MPaとし、気体噴射口とガラスフィルムとの距離は3mmとした。なお、ガラスフィルムは、曲率半径Rが3mmのうねりを有して搬送されていた。
本実施例においては、500m以上ガラスフィルムの破損なく、ガラスフィルムと靭性フィルムとを連続的に貼り合せることが可能であった。
実施例1と同様のガラスフィルムおよび靭性フィルムを用い、これらを1対のロール間(支持ロール/ニップロール間)で貼り合せた。ニップロールのゴム硬度は70度、ロール間でかかる線圧は2000Nとした。
本比較例においては、薄ガラスの破損が生じ、ガラスフィルムと靭性フィルムとを良好に貼り合せることができなかった。
