三氧化钼对无卤阻燃复合酚醛泡沫体系性能的影响
Effect of Molybdenum Trioxide on Flame Retardant Properties of Phenolic Foams Halogen-free System
摘要
Abstract
Halogen-free synergistic flame retardant system was composed of ammonium polyphosphate , pentaerythritol and molybdenum trioxide .The influences of the amount of MoO 3 on properties of flame retardant system composite phendic foans (FRSCPFS) including heat release, smoke release and mechanical properties , etc, were investigated.The results showed that compared with pure phenolic foam , average limit oxygen index ( ILO ) of FRSCPFs increased around 73%.The residual carbon (900 ℃) increased slightly when MoO3 amount≤ 1.5%, and then decreased.Heat release rate (HRR), total heat release (THR), oxygen consumption (O2C), and production of carbon monoxide and carbon dioxide (COP and CO2P) reduced about 75%, 68%, 68%, 28%and 41%, respectively.Average total smoke release (TSR) increased about 72%.Average rate of heat emission ( ARHE) decreased slightly when MoO 3 amount ≤1.5% and then increased.The flame retardant system was proved that flame retardant mainly played a role in the gas phase and agreed with the gas phase flame retarding mechanism by the increase of specific extinction area ( SEA ) and by the effect heat of combustion ( EHC ) .Average bending and compression strength reduced about 29% and 19%, respectively .By comprehensively comparing various performances , the properties of FRSCPFs were best when the amount of MoO 3 was 1.5%.关键词
