A damping composition with viscoelasticity for damping of noise and vibration the method for manufacturing a damping mat wih viscoelasticity and the construction method using the same

摘要

The present invention relates to a viscoelastic damping composition for reducing impact vibration generated by a floor impact source and a viscoelastic damping mat using the same. Also, it relates to a construction method for reducing noise between floors in an apartment house using the same. In the cushioning material for reducing noise and vibration between floors of an apartment house, 35 to 47% by weight of main oil dissolved in a heating liquid stirrer, 7 to 23% by weight of elastic rubber, 5 to 17% by weight of binder, 1 to 13% by weight of anti-aging agent, coagulant It relates to a viscoelastic damping composition for reducing noise and vibration, characterized in that it is composed of a mixture of 3 to 18% by weight, 1 to 8% by weight of reinforcing material, and 11 to 29% by weight of filler, and to a construction method for reducing noise and vibration between floors of a building using the same.
