Title (EN) INTERMEDIATE FILM FOR LAMINATED GLASS, AND LAMINATED GLASS
(FR) FILM INTERMÉDIAIRE POUR VERRE FEUILLETÉ ET VERRE FEUILLETÉ
(JA) 合わせガラス用中間膜及び合わせガラス
Abstract:
(EN) Provided is an intermediate film for laminated glass that makes it possible to increase the rigidity and the sound insulation properties of laminated glass, and to increase the recyclability of the intermediate film. The intermediate film for laminated glass is provided with a first layer and a second layer that is arranged on a first surface side of the first layer. The first layer comprises a polyvinyl acetal resin and a second resin component. The second layer comprises a polyvinyl acetal resin. The loss tangent peak temperature of the second resin component within the first layer is -30 °C to 10 °C. The refractive index of the second resin component within the first layer is 1.47 to 1.51.
(FR) L'invention concerne un film intermédiaire pour verre feuilleté qui permet d'augmenter la rigidité et les propriétés d'isolation acoustique d'un verre feuilleté, et d'augmenter la recyclabilité du film intermédiaire. Le film intermédiaire pour verre feuilleté comprend une première couche et une seconde couche qui est stratifiée sur une première surface de la première couche. La première couche comprend une résine d'acétal de polyvinyle et un second composant de résine. La seconde couche comprend une résine d'acétal de polyvinyle. La température maximale de la tangente de l'angle de pertes du second composant de résine à l'intérieur de la première couche est de -30°C à 10°C. L'indice de réfraction du second composant de résine à l'intérieur de la première couche est compris entre 1,47 et 1,51.
(JA)  合わせガラスの剛性を高めることができ、合わせガラスの遮音性を高めることができ、かつ中間膜のリサイクル性を高めることができる合わせガラス用中間膜を提供する。 本発明に係る合わせガラス用中間膜は、第1の層と、前記第1の層の第1の表面側に配置された第2の層とを備え、前記第1の層が、ポリビニルアセタール樹脂と、第2の樹脂成分とを含み、前記第2の層が、ポリビニルアセタール樹脂を含み、前記第1の層中の前記第2の樹脂成分が示す損失正接のピーク温度が-30℃以上、10℃以下であり、前記第1の層中の前記第2の樹脂成分の屈折率が1.47以上、1.51以下である。
