摘要
Disclosed is a vibration-attenuation composition which is excellent in attenuation of shock vibration generated by impact sources on floor structures. Also, disclosed are a vibration-attenuation sheet including the same and a vibration-attenuation block. More specifically, provided is a viscoelastic vibration-attenuation composition which comprises: 10-20 parts by weight of water; 10-30 parts by weight of a binder; 20-40 parts by weight of a first inorganic pigment; and 10-25 parts by weight of a second inorganic pigment. The vibration-attenuation sheet composed of the viscoelastic vibration-attenuation composition has low viscosity and high loss factors and storage modulus, thereby exhibiting outstanding vibration-attenuation effects. In addition, reduction in the floor noise is possible when the vibration-attenuation block is applied to multi-unit dwelling such as apartments.;COPYRIGHT KIPO 2016
