Title
(EN) INTERLAYER STRUCTURE FOR LAMINATED GLASS
(FR) STRUCTURE INTERCOUCHE POUR VERRE FEUILLETE
Abstract
(EN) The present invention relates to a multilayer aligned interlocked polyvinyl butryal composite structure which has good properties as a component in glass laminate structures, especially in those structures needing thick (greater than 0.76 mm) interlayers of PVB. The multilayer structures is produced by a process which uses two or more rollers containing plasticized PVB sheeting which are aligned and interlocked by simultaneous unwinding of the layers at set line speeds, temperatures and unwinding tensions.
(FR) L'invention concerne une structure composite multicouche de polyvinylbutyral entrecroisé, aligné et, présentant des bonnes propriétés en tant composant dans des structures de laminé de verre, notamment dans les structures nécessitant des intercouches épaisses de PVB (supérieures à 0,76 mm d'épaisseur). La structure multicouche est produite par un procédé qui consiste à utiliser deux rouleaux ou plus, comprenant des feuilles en PVB plastifiées qui sont alignées et entrecroisées par le déroulement simultané des couches aux vitesses de défilement, aux températures et aux tensions de déroulement fixées.
