The present invention relates to a sound-absorbing/insulating material having an excellent exterior and moldability and a method for producing same and, more specifically, to a sound-absorbing/insulating material and a method for producing same, the sound-absorbing/insulating material comprising: an inner sound-absorbing/insulating layer (1), which comprises a first non-woven fabric comprising heat-resistant fibers as main constituents and a binder evenly distributed inside the first non-woven fabric in the form of maintaining the three-dimensional shape of the inside of the first non-woven fabric; and an outer sound-absorbing/insulating layer (2', 2"), which comprises a second non-woven fabric comprising heat-resistant fibers as main constituents, the sound-absorbing/insulating material having a structure in which the outer sound-absorbing/insulating layer is stacked on one side or both sides of the inner sound-absorbing/insulating layer. The sound-absorbing/insulating material according to the present invention has excellent sound-absorbing properties, flame retardancy, heat resistance, heat-insulating properties, and high-temperature moldability and, in particular, by having the outer sound-absorbing/insulating layer(s), eliminates all risk of the binder being smeared on a mold during molding and consequently damaging the exterior of a molded product. |
