(EN) INTERMEDIATE FILM FOR LAMINATED GLASSES, AND LAMINATED GLASS
(FR) FILM INTERMÉDIAIRE POUR VERRES FEUILLETÉS, ET VERRE FEUILLETÉ
Abstract
(EN)
The present invention provides an intermediate film for laminated glass that can increase the heat-insulating properties of laminated glass. The intermediate film for laminated glass according to the present invention is an intermediate film for laminated glass having a one-layer structure or a laminated structure of two or more layers, an intermediate film 1 for laminated glass has a first layer 2 containing silicon dioxide particles 51 having hollow parts and shell parts and having a porosity of 40% or more and 80% or less, when the intermediate film 1 for laminated glass has a one-layer structure, the first layer further contains a thermoplastic resin, and when the intermediate film 1 for laminated glass has a laminated structure of two or more layers, the intermediate film 1 for laminated glass further has a second layer 3 which is arranged on a first surface 2a side of the first layer 2 and which contains a thermoplastic resin.

(FR)
Le film intermédiaire pour verres feuilletés ci-décrit peut augmenter les propriétés d'isolation thermique des verres feuilletés. Ce film intermédiaire pour verres feuilletés a une structure monocouche ou une structure stratifiée composée d'au moins deux couches. Le film intermédiaire (1) pour verres feuilletés implique une première couche (2) comportant des parties creuses et des parties de coque, a un taux de porosité de 40 à 80 % inclus et contient des particules de dioxyde de silicium (51). Quand le film intermédiaire pour verres feuilletés a une structure monocouche, la première couche contient, en plus, une résine thermoplastique. Quand le film intermédiaire (1) pour verres feuilletés a une structure stratifiée composée d'au moins deux couches, le film intermédiaire (1) pour verres feuilletés implique, en plus, une seconde couche (3) formée sur une première surface (2a) de la première couche (2) et qui contient une résine thermoplastique.
