摘　　要：以多聚磷酸铵、季戊四醇、氯化亚铜为原料组成膨胀型阻燃系统，研究氯化亚铜添加量对膨胀型阻燃系统复合酚醛泡沫的极限氧指数、燃烧热量释放速率、燃烧总热释放量、比消光面积、有效燃烧热量、耗氧量、烟气密度和有毒气体释放等的影响。结果表明：阻燃体系复合泡沫的极限氧指数在71．5％～73．5％之间，具有良好的阻燃性；阻燃体系对酚醛泡沫的阻燃符合气相阻燃的机理，并且在氯化亚铜添加量为1．0％～1．5％时，阻燃体系复合泡沫的阻燃性能最优。This paper investigated the effect of cuprous chloride on flame retardancy properties of phenolic foam compos- ite with flame retardancy system consisted of ammonium polyphosphate, pentaerythritol and cuprous chloride. We dis- cussed in detail the effect of cuprous chloride on limited oxygen index （ILOI）, heat release rate （ RHRR ）, total heat re- lease （ qTns ）, specific extinction area （ qSEA ）, effective heat of combustion （ qEHC ）, oxygen consumption （ qO2C ）, total smoke release （qTss）, carbon monoxide production （qcoP） and carbon dioxide production （qCOL2P ） etc. Experimental re- suits showed that phenolic foam composites exhibited good flame retardancy with such flame retardancy system, the ILOI of which ranged from 71, 5% to 73.5%. Flame retardant system functioned in accordance with the gas-phase flame retar- dancy mechanism in the phenolic foam composite. Phenolic composite showed the best flame retardaney as the content of cuprous chloride in the range of 1.0% -1.5% in the composite system.
