摘　　要：研究阻燃剂体系及用量对丁基橡胶阻尼片氧指数、烟密度和阻尼性能的影响。结果表明:氢氧化铝阻燃体系与聚氯乙烯阻燃体系相比具有更低的烟密度和更高的阻尼性能;阻燃协效剂的加入有利于提高阻尼片的阻燃性能并降低烟密度,但会使阻尼片的损耗因子最大值降低;当阻燃剂与阻燃协效剂用量比为20∶2时,阻尼片的阻尼性能最稳定。The effects of flame retardant system and addition level on the oxygen index, smoke den- sity and damping performance of the IIR damping sheets were investigated. The results showed that, AI（OH）3 flame retardant system had lower smoke density and higher damping performance than PVC flame retardant system. Synergistic agent could improve the flame retardant properties and reduce the smoke density. But it decreased the maximum loss factor of the material at the same time. When the blend ratio of flame retardant and synergistic agent was 20 ： 2,the damping sheets showed the most stable damping performance.
