Title (EN) INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS
(FR) INTERCOUCHE 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) An interlayer for laminated glass is provided which is capable of improving the bending rigidity of a laminated glass over a wide range of temperatures, and which is capable of improving sound insulation properties of the laminated glass. An interlayer for laminated glass according to the present invention is provided with a phase separation structure which includes a polyvinyl acetal resin, and a polymer of a polymerizable component including a (meth)acrylate compound having two or more (meth)acryloyl groups. The content of the polymer is at least 75 but not more than 150 parts by weight per 100 parts by weight of the polyvinyl acetal resin. The glass transition temperature of a component derived from the polymer is in the range of -20˚C to 5˚C inclusive.
(FR) La présente invention concerne une intercouche pour verre feuilleté capable d’améliorer la rigidité à la flexion d’un verre feuilleté sur une large plage de températures, et qui est capable d’améliorer les propriétés d’isolation sonore du verre feuilleté. Une intercouche pour verre feuilleté selon la présente invention est munie d’une structure à séparation de phase qui comprend une résine de polyvinyl acétal, et un polymère d’un constituant polymérisable comprenant un composé (méth)acrylate ayant deux groupes (méth)acryloyle ou plus. La teneur du polymère est d’au moins 75 mais de pas plus de 150 parties en poids pour 100 parties en poids de la résine de polyvinyl acétal. La température de transition vitreuse d’un constituant dérivé d’un polymère se situe dans la plage de -20 °C à 5 °C inclus.
(JA) 合わせガラスの曲げ剛性を広い温度範囲に渡り高めることができ、かつ合わせガラスの遮音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、ポリビニルアセタール樹脂と、(メタ)アクリロイル基を2個以上有する(メタ)アクリレート化合物を含む重合性成分の重合体とを含み、前記ポリビニルアセタール樹脂100重量部に対して、前記重合体の含有量が75重量部以上150重量部以下であり、前記重合体に由来する成分のガラス転移温度が-20℃以上5℃以下であり、相分離構造を有する。
