Abstract
The present invention relates to a sound-absorbing material and a method for preparing same. More particularly, it relates to a sound-absorbing material prepared by impregnating a binder into a nonwoven fabric formed of a heat-resistant fiber, having superior sound-absorbing property, flame retardancy, heat resistance and heat-insulating property, thus being applicable to parts maintained at high temperatures of 200° C. or above, to say nothing of room temperature, and being shapeable owing to the binder, and a method for preparing same.
