| description | The utility model discloses a fireproof sound-absorbing board for a central substation, which comprises a closed-cell foamed aluminum board (1), an open-cell foamed aluminum board (2) and a polyester fiber sound-absorbing board (3), the closed-cell foamed aluminum board (1) and the polyester fiber sound-absorbing board (3) are bonded into a whole, a cavity (4) is arranged between the polyester fiber sound-absorbing board (3) and the open-cell foamed aluminum board (2), and the open-cell foamed aluminum board (2) is arranged in the cavity (4). The closed-cell foamed aluminum plate (1) and the polyester fiber acoustic panel (3) are positioned outside, and the open-cell foamed aluminum plate (2) is positioned inside. The sound-absorbing fireproof door is good in sound-absorbing effect and excellent in fireproof performance, not only meets the fireproof requirement of the substation, but also has the effect of noise reduction, reduces harm of noise to workers, and guarantees physical and psychological health.
