Title (EN) COVER MATERIAL FOR ACOUSTIC INSULATION AND ENGINE UNIT
(FR) MATÉRIAU DE PROTECTION POUR ISOLATION ACOUSTIQUE ET GROUPE MOTEUR
(JA) 防音用被覆材およびエンジンユニット
Abstract:
(EN) Provided is a novel cover material for acoustic insulation that has heat resistance and that even if thin has sufficient acoustic insulation performance. A cover material for acoustic insulation characterized in that a first elastic porous body, a porous film having an open hole ratio of 0.1-5% and an open hole diameter of 50-500 µm, and a second elastic porous body are layered in this order, a surface material preferably also being provided to at least one of the outer surface side of the first elastic porous body and the outer surface side of the second elastic porous body.
(FR) L'invention concerne un nouveau matériau de protection pour isolation acoustique qui possède une résistance à la chaleur et qui, même s'il est mince, présente une performance d'isolation acoustique suffisante. Le matériau de protection pour isolation acoustique est caractérisé en ce qu'un premier corps élastique poreux, un film poreux présentant un rapport de trous ouverts de 0,1 à 5 % et un diamètre de trou ouvert de 50 à 500 µm, et un second corps élastique poreux sont stratifiés dans cet ordre ; un matériau de surface est de préférence également appliqué sur la surface externe du premier corps élastique poreux et/ou la surface externe du second corps élastique poreux.
(JA) 耐熱性を有し、厚さが薄くても十分な防音性能を有する新規な防音用被覆材を提供する。 第一の弾性多孔質体と、開孔率が0.1~5%で開孔径が50~500μmである多孔質フィルムと、第二の弾性多孔質体とが、この順番に積層されてなることを特徴とする防音用被覆材であり、好ましくは、上記第一の弾性多孔体の外表面側および第二の弾性多孔質体の外表面側の少なくとも一方にさらに表皮材を有する防音用被覆材である。
