Patent

CA 2709794

A lightweight sound absorbing surface material, having an excellent sound absorbing property and moldability, and a sound absorbing material using the sound absorbing surface material, are provided in the present invention. The sound absorbing surface material 6 is manufactured by laminating stretchable paper(s) which is (are) creped and/or embossed (such as a creped paper 1b) onto one or both sides of a fiber sheet 3. The degree of creping of the paper is in the range of between 10 and 50 %, and the height of projections of the embossed paper is in the range of between 0.02 and 2.00 mm, with the number of the projections being in the range of between 20 and 200 projections/cm2. Further, the sound absorbing surface material 6 is laminated onto a air permeable sheet of porous material 7, to manufacture a sound absorbing material 8.

L'invention porte sur un matériau de revêtement d'absorption de son de faible poids qui a une excellente absorption du son et une excellente aptitude au moulage ; et sur un matériau d'absorption du son l'utilisant. Une feuille de fibres (3) sur l'une de ses surfaces principales ou sur ses deux surfaces principales est stratifiée avec un matériau de papier étiré crêpé et/ou gaufré (par exemple, du papier crêpé (1b)), de façon à obtenir ainsi un matériau de revêtement d'absorption de son (6). Le matériau de papier étiré a un rapport de crêpé de 10 à 50 %, une hauteur de saillie de 0,02 à 2,00 mm et une quantité de saillie de 20 à 200 saillies/cm2. Le matériau de revêtement d'absorption de son (6) est stratifié avec un matériau poreux respirant en forme de feuille (7) de façon à obtenir ainsi un matériau d'absorption de son (8).
