ABSORBENT AND SOUND INSULATION MATERIAL; METHOD FOR MANUFACTURING ABSORBENT AND SOUND-INSULATING MATERIAL; AND METHOD FOR REDUCING NOISE FROM A NOISE GENERATING DEVICE. The present invention relates to a sound-absorbing and insulating material and a method for manufacturing the same, more particularly to a sound-absorbing and insulating material obtained by impregnating a polyimide binder in a non-woven fabric made of a heat-resistant fiber. heat, with superior sound-absorbing property, flame retardancy, heat resistance and heat resistance, thus being applicable to parts kept at high temperature of 300ºC as well as ambient temperature, and moldability due to the use of wood binder. polyimide, and a method for making the same. |
