Title
(EN) TECHNOLOGY FOR ATTACHING FACING SYSTEM TO INSULATION PRODUCT
(FR) SOLIDARISATION D'UN SYSTEME DE PAREMENT SUR UN PRODUIT ISOLANT
Abstract
(EN) An insulation product (60) includes an elongated batt (62) of fibrous insulation material, and a facing (64) adhered to a major surface of the batt. The facing is a coextruded polymer film of barrier (70) and bonding (72) (and preferably carrier) layers, with the bonding layer having a softening point lower than the softening point of the barrier layer. The bonding layer can include one or more of ethylene N-butyl acrylate, ethylene methyl acrylate, low density polyethylene and ethylene ethyl acrylate. When the facing has been heated to a temperature above the softening point of the bonding layer, but below the softening point of the barrier layer, the facing is adhered to the batt by the attachment of the bonding layer to the fibers in the batt due to the softening of the bonding layer. The heating can be either conduction heating or ultrasonic heating. Also disclosed is a technology for ultrasonically brazing two pieces of plastic together.
(FR) La présente invention concerne un produit isolant (60) fait, d'une part d'un panneau isolant semi-rigide (62) de forme allongée à base de fibres, et d'autre part d'un parement (64) solidarisé sur une surface principale du panneau isolant. Le parement est un film réunissant des couches polymères coextrudées de matériau barrière (70) et de matériau de liaison (72) (et de préférence de matériau support), le point de ramollissement de la couche de la couche de liaison étant inférieur à celui de la couche barrière. Les produits utilisables pour la couche de liaison sont essentiellement l'éthylène N-butyle-acrylate, l'éthylène méthyle-acrylate, le polyéthylène basse densité et l'éthylène éthyle-acrylate. Une fois que le parement a été chauffé à une température supérieure au point de ramollissement de la couche de liaison mais inférieure au point de ramollissement de la couche barrière, pour faire tenir le parement sur le panneau isolant semi-rigide, on profite de la fixation de la couche de liaison sur les fibres du panneau isolant grâce au ramollissement de la couche de liaison. Le chauffage peut se faire par conduction ou par ultrasons. Pour le chauffage par ultrasons, la résonance de la couche de liaison intervient à une fréquence ultrasonique différente de la fréquence de résonance de la couche barrière. L'invention concerne également un procédé de brasage par ultrasons de deux pièces de plastique. A cet effet, on utilise une couche de soudure en plastique (1106), notamment un polymère coextrudé, disposé entre deux pièces en plastique ou en composite (1102, 1104) et on leur applique une énergie ultrasonique de façon à souder à la première et à la seconde pièce la couche de soudure plastique. Ce procédé de brasage ultrasonique permet de réunir des pièces en plastiques différents.
