The invention relates to a damping board which comprises a cured linen and cotton felt layer. A foam resin layer is arranged above the cured linen and cotton felt layer, and an aluminum foil layer is arranged below the cured linen and cotton felt layer. The cured linen and cotton felt layer is arranged to be used for absorbing sounds and reducing noise. The foam resin layer is arranged, and the foam resin layer is small in weight, good in dimensional stability, resistant to chemical corrosion, good in heat resistance, resistant to combustion and low in price and is a relatively ideal insulation and thermal insulation material. The aluminum foil layer is arranged to be used for thermal insulation and noise reduction. The damping board is reasonable in design and capable of being popularized on a large scale. 本发明涉及种阻尼板，包括固化麻棉毡层，所述固化麻棉毡层上方设有发泡树脂层，下方设有铝箔层，通过设置固化麻棉毡层，用于吸音降噪；通过设置发泡树脂层，发泡树脂重量轻，尺寸稳定性好，耐化学腐蚀，耐热性好，难燃，价格低廉，是较为理想的绝缘隔热保温材料；通过设置铝箔层，用于隔热、降噪，本发明设计合理，可大规模推广。
