摘　　要：为研究聚氨酯保温材料的产烟性能,基于磷系阻燃剂(PFR)和可膨胀石墨(EG)对聚氨酯保温材料进行改性。通过测试常规与改性聚氨酯保温材料的产烟密度及一氧化碳(CO)释放量,对比分析PFR与EG对聚氨酯保温材料产烟性能的影响。结果显示,PFR改性聚氨酯保温材料燃烧的烟气密度提高近20%,CO释放量下降约33%,且三(1,3-二氯异丙基)磷酸酯(TDCPP)与四(2-氯乙基)二亚乙基醚二磷酸酯(CR-505)配比对产烟性能影响相差无几; PFR与EG协同使用时,烟气密度大幅度下降,在减低CO释放量方面形成了协同叠加作用,能减低聚氨酯保温材料烟气的毒性。In order to study the smoke releasing performance of polyurethane insulation materials, polyurethane insulation materials were modified based on phosphorus flame retardant （PFR） and expandable graphite （EG）. The effects of PFR and EG on the smoke releasing performance of polyurethane thermal insulation materials were compared and analyzed by testing the smoke density and carbon monoxide （CO） release quantity of the conventional and modified polyurethane insulation materials. The results show that the combustion smoke density of PFR modified polyurethane increases nearly 20% , CO release decreases by about 33%, and the ratio of tris（ 1, 3-dichloro-2-propyl ） phosphate （TDCPP） to tetra （2-chloro ethyl） diethyleneether diphosphate （CR-505） has almost no difference in smoke production. When PFR and EG are used in collaboration with EG, the density of smoke is decreased dramatically. The decrease of CO can form a synergistic superposition effect in reducing the amount of release, which can reduce the toxicity of polyurethane insulation materials.
