COMPOSITION FOR SOUND-BLOCKING SHEET MEMBER, SOUND-BLOCKING SHEET MEMBER, AND SOUND-BLOCKING STRUCTURE BODY
Provided are: a composition for a sound-blocking sheet member having excellent sound-blocking performance; the sound-blocking sheet member; and a sound-blocking structure body. In the sound-blocking structure body, which has a plurality of protuberant, rubbery resonant parts, and a sheet-form support body that supports the resonant parts, the resonant parts have a storage elasticity G' of 100 MPaor less at 25 DEG C and 10 kHz as obtained from the synthetic curve of dynamic viscoelasticity according to ISO6721-4, and the surface density of the support body is 1.0 kg/m<2> or less.
本发明提供隔音性能优异的隔音片部件用的组合物、隔音片部件和隔音结构体。一种隔音结构体，具有多个凸状的具有橡胶弹性的共振部、以及支撑所述共振部的片状支撑体，该共振部由按照ISO6721－4的动态粘弹性的主曲线得到的储能模量G’在25℃、10kHz时为100MPa以下，该支撑体的面密度为1.0kg/m2以下。
