FLOOR IMPACT NOISE ISOLATOR/SHOCK-ABSORBER WITH NON-WOVEN FABRIC FOR CONSTRUCTION

摘要

An isolator/shock-absorber for construction having a non-woven fabric is provided to increase a space and a passage of a cell for noise absorption so that noise and vibration caused by impact can be effectively absorbed and distributed with a fabric thread of the non-woven fabric having orientation crimped in z-direction. An isolator/shock-absorber(100) for construction comprises a non-woven fabric(10), which has a fabric thread crimped in z-direction. The non-woven fabric has a density in a range of 10kg/m^3 to 35kg/m^3, a dynamic elastic modulus in a range of 1MN/m^3 to 35MN/m^3, and a thickness in a range of 15mm to 50mm. A foam(30) having cells(32) and unevenness(35) is bonded on one side or both sides of the non-woven fabric, to improve shock absorbing capability and heat insulating performance.
