富孔吸音声屏障材料设计与性能研究
Material Design and Performance Study of Porous Sound-absorbing Noise Barrier
摘要
Abstract
A new porous sound-absorbing noise barrier material was prepared using quartz sand and self-developed polysiloxane resin,and the forming process of the material was investigated.The test specimens of the porous sound-absorbing noise barrier were prepared with different mesh numbers of quartz sand and different proportions of resin,and the void property,compres-sive strength,durability and acoustic performance were investigated.The results show that:①base on the test results of air voids,connected air voids and compressive strength,the 20 mesh quartz sand and 10∶1 mass ratio of quartz sand to resin are suggested to prepare the porous sound-absorbing rock noise barrier material;②the porous sound-absorbing noise bar-rier material demonstrates good resistance to salt corrosion and alkali corrosion,but relatively poor resistance to acid corrosion;meanwhile,it exhibits excellent water stability and freeze-thaw stability;③the porous sound-absorbing noise barri-er material has excellent acoustic performance,the noise reduction coefficient reaches 0.7 and the weighted sound reduc-tion index reaches 40 dB,which are higher than the requirements of current noise barrier specifications.关键词
