浅谈聚氨酯硬泡保温材料阻燃技术

摘要

Rigid polyurethane foam insulation materials belonged to the organic polymer insulating material,and the thermal conductivity of insulation materials was the lowest of all and had the most superior thermal performance.The combustion process of polyurethane thermal insulation material was introduced,and the flame retardant methods of rigid polyurethane foam insulation materials and its development trend were elaborated.%聚氨酯硬泡保温材料属于有机高分子保温材料,其导热系数为所有保温材料中最低、热工性能最为优越的一类材料。介绍了聚氨酯硬泡保温材料的燃烧过程,阐述了聚氨酯硬泡保温材料的阻燃处理方法及其发展趋势。
