有机保温材料燃烧烟气毒性及热性能分析

摘要

采用极限氧指数、垂直燃烧性能、材料燃烧总热值及微型量热测试,热重红外联用(TG-FTIR)分析,小白鼠动物染毒试验,系统对比研究了模塑聚苯乙烯泡沫(EPS)、硬质聚氨酯泡沫(PUF)及酚醛泡沫(PF)等3种常见有机保温材料的燃烧性能、热稳定性、气相分解产物及产烟毒性.%The flammability,thermal degradation behaviors,gas phase decomposition products and effluents hazard of EPS,PUF and PF were investigated comparatively by the limiting oxygen index test,vertical burning test,the gross heat of combustion(PCS) measurements,microscale combustion calorimetry(MCC)and thermogravimetry combined with FTIR spectrometry(TG-FTIR). And fire effluents hazard of organic thermal insulation materials were investigated by mice exposure test.
