LOW NOISE, ADIABATIC, SOUND-INSULATING, DUSTPROOF MATERIALS FOR INTERLAYER FLOOR OF BUILDING, COMPOSED OF POLYETHYLENE FOAMING CUSHION MATERIALS WITH CLOSED CEL, FELT INTERMEDIATE MATERIALS, AND POLYETHYLENE FOAMING CUSHION MATERIALS

摘要

PURPOSE: Low noise, adiabatic, sound-insulating and dustproof materials for an interlayer floor of a building is provided to prevent the oscillating noise by impact and thermal loss using materials placed on an apartment house, a tenement house, an individual home and a general building. CONSTITUTION: The low noise, adiabatic, sound-insulating and dustproof materials for an interlayer floor of a building comprise surface materials(1-1) composed of polyethylene foaming cushion materials with closed cell, felt intermediate materials(1-2) formed by impregnating asphalt to paper manufactured by mixing pulp and cotton textiles, and polyethylene foaming cushion materials(1-3) with close cell.
