Abstract

The invention discloses a sound insulating pad for an automotive carpet. The sound insulating pad comprises a first sound insulating felt, a first foamed polypropylene layer, a sound-absorbing panel, a second foamed polypropylene layer, sound-absorbing sponge and a second sound insulating felt, wherein the first foamed polypropylene layer and the second foamed polypropylene layer are connected to the upper surface and the lower surface of the sound-absorbing panel by a high-temperature laminating mode; the first sound insulating felt is attached to the upper surface of the first foamed polypropylene layer; the second sound insulating felt is arranged below the second foamed polypropylene layer; and the sound-absorbing sponge is arranged between the second foamed polypropylene layer and the second sound insulating felt. By adoption of the mode, the sound insulating pad for the automotive carpet, disclosed by the invention, can be used for effectively absorbing sound and effectively adsorbing outside noises, and has excellent sound absorbing and heat insulating effects; and when the sound insulating pad is impacted, a good buffer effect can be realized, and a quiet automobile indoor environment can be created.
