摘要/Abstract

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。

Abstract: This paper investigated the effect of cuprous chloride on flame retardancy properties of phenolic foam composite with flame retardancy system consisted of ammonium polyphosphate, pentaerythritol and cuprous chloride. We discussed in detail the effect of cuprous chloride on limited oxygen index(I_LOI), heat release rate(R_HRR), total heat release(q_THR), specific extinction area(q_SEA), effective heat of combustion(q_EHC), oxygen consumption(q_O₂C), total smoke release(q_TSR), carbon monoxide production(q_COP)and carbon dioxide production(q_CO₂P)etc. Experimental results showed that phenolic foam composites exhibited good flame retardancy with such flame retardancy system, the I_LOI of which ranged from 71.5% to 73.5%. Flame retardant system functioned in accordance with the gas-phase flame retardancy mechanism in the phenolic foam composite. Phenolic composite showed the best flame retardancy as the content of cuprous chloride in the range of 1.0% -1.5% in the composite system.
