The invention discloses a strong sound absorption member for traffics and its preparation method and application, the sound absorption member includes a micropore sound absorption film layer, a fitting firm layer and a sound absorption
sheet material layer. The preparation method is as follows: preparing materials of the micropore sound absorption film layer and the sound absorption
sheet material layer, feeding the materials,
die cutting the sound absorption
sheet material layer for molding, unreeling the micropore sound absorption film layer, arranging the fitting firm layer in the micropore sound absorption film layer, fitting the micropore sound absorption film layer and the die-
cut molded sound absorption sheet material layer for
coating and compounding, heating a joint seam for sealing,
processing a hole or a hasp, reinforcing a
honing seam for connection, testing,
ripening at
room temperature, storing, inspecting and packing. The strong sound absorption member for the traffics is used for seat cushions in
carriage of transportation equipment, seat cushions of cars and wall hanging members in a subway platform. The strong sound absorption member can obviously absorb various frequency noises of the traffics, greatly reduces the
noise value of traffic facilities, gives a person a serene trip and travel environment, and greatly reduces adverse effects on health and safety issues caused by
traffic noise fatigues.
