NOISE-INTERCEPTION SHEET TO REDUCE THE FLOOR IMPACT NOISE AND TO IMPROVE THE THERMAL INSULATION PERFORMANCE IN APARTMENT HOUSE AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: interlayer noise prevents material for reducing interlayer noise apartment, improves performance of insulation and preparation method thereof, provides and suitably meet noise criteria, by being effectively reduced interlayer noise like heavy impact sound, lightweight strike note, etc.. ;CONSTITUTION: interlayer noise prevents material for reducing interlayer noise apartment, improves the performance of insulation by superficial layer (22), damping and sound absorbing layer, sound insulation layer (25), insulating layer (21). It includes thermoplastic polyurethane resin that superficial layer, which is by high rigidity polymer resin,. Damping and sound absorbing layer, by vibration-proof material (23) and sound-absorbing material (24). The cellular rubber that the vibration-proof material is formed into. The vibration-proof material reduces heavy impact sound and above-mentioned lightweight strike note. The foam that sound-absorbing material is formed into. Sound-absorbing material reduces sound absorption function of the noise by vibration-damping function. The sound insulation layer is non-woven fabrics made of nanometer or micro fiber. The sound insulation layer cuts off lightweight strike note. Semi-rigid foam made of the thermal insulation layer or rigid foam. ;The 2010 of copyright KIPO submissions
