Abstract

La présente invention se rapporte à un intercalaire pour verres feuilletés comprenant deux couches externes en un matériau choisi parmi le poly(butyral de vinyle) (PVB) et le poly(éthylène-acétate de vinyle) (EVA), assemblées au moyen d’une couche adhésive d’amortissement viscoélastique formée par un matériau comprenant: - de 21% à 62% en poids d’au moins un polymère acrylique, par rapport au poids total du matériau sec, de préférence de 21% à 51% en poids, et plus préférentiellement de 21% à 35% en poids, - de 17% à 60% en poids d’au moins un agent tackifiant, par rapport au poids total du matériau sec, de préférence de 22% à 35% en poids, et plus préférentiellement de 22% à 26% en poids, et - de 7% à 43% en poids d’au moins un agent plastifiant, par rapport au poids total du matériau sec, de préférence de 12% à 31% en poids et plus préférentiellement de 16% à 26% en poids. La présente invention concerne également un procédé de fabrication d’un intercalaire tel que mentionné ci-dessus ainsi qu’un vitrage feuilleté comprenant un tel intercalaire et son utilisation comme pare-brise de véhicule et/ou comme vitrage de bâtiment.
