| Abstract: | This study used recycled fibers and inflaming retarding fibers to form composite nonwoven and then compounded with PU foam preparing composite board with sound-absorbing, thermal-insulating and cushion properties. Effects of foam density and composite nonwoven on three properties of PU composite board have studied. Result shows that, with increase of foam density, composite boards had higher sound absorbing coefficient at medium and high frequencies, lower thermal insulation as well as firstly improved and then decreased cushion property. After assessment, the optimal foam density was 60 kg/m3. For diverse requirements, PU foam matches with different kinds of composite nonwoven to achieve excellent cushion property. The resulting composite board can effectively ease hurts from rigid wall, and could be applied in kindergarten, music hall, audio-visual room, pub and recreational centre etc in the future. |
