Title
(EN) RESIN COMPOSITION FOR ACOUSTIC MATCHING LAYER
(FR) COMPOSITION DE RÉSINE POUR COUCHE D'ADAPTATION ACOUSTIQUE
(JA) 音響整合層用樹脂組成物
Abstract
(EN)
The present invention provides a resin composition for an acoustic matching layer, the resin composition capable of holding uniform dispersibility of a hollow filler and suppressing foaming, and having excellent moldability and handleability. This resin composition for an acoustic matching layer includes resin, a hollow filler, and a thixotropy imparting agent, wherein the viscosity thereof measured under the condition of 25°C, rotor No. 4, and 0.3 rpm using a B-type viscometer is 1130-4000 Pa∙s, and a thixotropic index represented by a ratio (V1/V2) between a viscosity (V1) measured under the condition of rotor No. 4, and 0.3 rpm and a viscosity (V2) measured under the condition of rotor No. 4, and 1.5 rpm, respectively, at 50°C using the B-type viscometer is 3.0-5.0.

La présente invention concerne une composition de résine pour une couche d'adaptation acoustique, la composition de résine pouvant maintenir une dispersibilité uniforme d'une charge creuse et supprimer le moussage, et ayant une excellente aptitude au moulage et une excellente maniabilité. Cette composition de résine pour une couche d'adaptation acoustique comprend une résine, une charge creuse et un agent conférant une thixotropie, la viscosité de celle-ci étant mesurée à 25°C, rotor n°4 à 0,3 tr/min à l'aide d'un viscosimètre de type B est de 1130-4000 Pa∙s, et un indice thixotrope représenté par un rapport (V1/V2) entre une viscosité (V1) mesurée sous l'état du rotor n°4 à 0,3 tr/min et une viscosité (V2) mesurée sous l'état du rotor n°4 à 1,5 tr/min, respectivement, à 50°C à l'aide du viscosimètre de type B est entre 3,0 et 5,0.
