The invention discloses an industrial sound-absorbing dry-hanging plate, which is prepared from the following raw materials in percentage by mass: 65-70% of water-quenched slag, 25-28% of bulk rock wool, 3% of a water-borne epoxy resin and 2% of talcum powder. According to the invention, the particle shapes of the material are different; under the condition of the same projection area, the specific surface area can increase the area exposed in sound waves so as to increase the effective sound absorption area and the edge effect to a certain extent, so that the sound absorption characteristic of the material is improved, and the high-frequency sound absorption coefficient of the material can reach 0.6-0.9 through tests; and the water-quenched slag of the waste gas can be reutilized, so that the resource waste is prevented, and the environmental pollution caused by direct emission is also prevented to a certain extent.
本发明公开了一种工业吸音干挂板，所述一种工业吸音干挂板的制造原料包括水淬渣、散状岩棉、水性环氧树脂和滑石粉，所述制造原料的质量百分比为水淬渣65‑70％、散状岩棉25‑28％、水性环氧树脂3％、滑石粉2％。发明中材料颗粒形状各异，在相同投影面积情况下，比表面积大便可以增大暴露在声波中的面积，一定程度上增加了有效的吸声面积和边缘效应，因此提高了材料的吸声特性，经测试其高频吸声系数可达0.6‑0.9；并且本发明可以对废气的水淬渣进行二次利用，防止了资源浪费，也一定程度上防止了直接排放造成的环境污染。
