Title
(EN) LAMINATED GLASS
(FR) VERRE FEUILLETÉ
(JA) 合わせガラス
Abstract
(EN)
Provided is a laminated glass which has a high sound insulation performance and excellent foaming resistance of an interlayer, in particular, excellent foaming resistance of an interlayer in the periphery thereof. The laminated glass includes a pair of glass sheets which face each other, and the interlayer which: is sandwiched between the pair of glass sheets; has skin layers with a glass transition point of 15°C or higher and core layers with a glass transition point of less than 15°C that are alternately laminated, each layer containing a polyvinyl acetal resin and a plasticizer; has three or more layers of the core layer; and contains the plasticizer in an amount of 0.3 mg/mm2 or more per unit area of the principal surface of the interlayer measured in a region from 5 mm to 6 mm inward from an edge of the interlayer.

L'invention porte sur un verre feuilleté qui a une performance d'isolation acoustique élevée et une excellente résistance au moussage d'une couche intermédiaire, en particulier une excellente résistance au moussage d'une couche intermédiaire à sa périphérie. Le verre feuilleté comprend une paire de feuilles de verre qui se font face et la couche intermédiaire, qui : est prise en sandwich entre la paire de feuilles de verre; possède des couches de peau présentant un point de transition vitreuse de 15°C ou plus et des couches de noyau présentant un point de transition vitreuse inférieur à 15°C qui sont stratifiées en alternance, chaque couche contenant une résine de polyvinylacétal et un plastifiant; possède au moins trois couches de couche de noyau; et contient le plastifiant dans une quantité de 0,3 mg/mm2 ou plus par unité de surface de la surface principale de la couche intermédiaire mesurée dans une région allant de 5 mm à 6 mm vers l'intérieur à partir d'un bord de la couche intermédiaire.
