摘　　要：选用废旧橡胶粉、玻璃纤维织物和聚氯乙烯制备了废旧橡胶粉／玻纤织物／聚氯乙烯（WTRP／GF／PVC）复合材料。分别利用双声道分析仪、DMA、万能材料试验机、自动氧指数测定仪等对材料的隔声性能、动态力学性能、拉伸性能及阻燃性能等进行了测试。结果表明：WTRP／GF／PVC复合材料与GF／PVC相比，隔声性能没有降低，在低频段（200-630Hz）和高频段（1600-8000Hz）隔声量略有提高，中高频段（630-1600Hz）隔声量很接近，而常温以上的阻尼性能显著提高；随着WTRP含量的增加，隔声量在整个频率段变化不明显，拉伸强度先上升后下降，LOI值缓慢增加。Waste rubber powder/Glass fabric/PVC（WTRP/GF/PVC）composite is prepared by choosing waste rubber powder, glass fabric and PVC. The sound insulation, dynamic mechanical, tensile and fire-retardant properties of materials are respectively measured by the two-channel acoustic analyzer, DMA, universal material testing machine, and automatic oxygen index detector, etc. The results shows： compared with GF/PVC composite, the sound insulation property of WTRP/GF/PVC composite don＇t reduce, whose sound reduction loss slightly increases in low frequencies（200 Hz to 630 Hz）and high frequen cies（1600 Hz to 8000 Hz）, but is very close in high-frequencies（630 Hz to 1600 Hz）. Moreover, its damp ing property above room temperature significantly increases; With the increase of the content of WTRP, the composites don＇t change obviously in the sound reduction loss among the entire frequencies, have a de cline after a first increase in tensile strength, and have a slow increase in LOI value.
