Zusammenfassung: | The utility model relates to the technical field of interior trim panels, and discloses a flame-retardant noise-reduction interior trim panel for a train compartment, which solves the problems that the existing noise-reduction interior trim panel for the train compartment is single in function and poorer in noise-reduction performance and affects the riding experience of passengers and drivers, and comprises a base layer, the upper end of the base layer is connected with a wear-resistant layer, and the lower end of the base layer is connected with a purification layer. Under the absorption action of the sound absorption layer and the sound absorption groove, a part of sound waves are absorbed, the rest of sound waves enter the sound insulation layer and then enter the silencing cavity, the other part of sound waves are absorbed under the cooperation of the corrugated plate, and therefore the purposes of sound absorption and noise reduction are achieved. The comfort level of passengers is further improved; the |
