阻燃聚氨酯硬泡阻燃剂的研究进展

摘要

The combustion degradation process of rigid polyurethane foam,the flame retardant mechanisms of flame retardant and the common flame retardants for rigid polyurethane foams were reviewed.The latest development of flame retardants in the rigid polyurethane foam was summarized.The synergistic effects of addition-type flame retardants and between addition-type and reactive-type flame retardants were also emphasized.The future development prospect of flame retardants in the rigid polyurethane foams was elaborated.%简要介绍了硬质聚氨酯泡沫的燃烧降解过程,并对其阻燃机理以及常用阻燃剂进行了全面概述.总结了近年来国内外有关聚氨酯泡沫阻燃剂的研究进展,重点介绍了添加型阻燃剂协同、添加型和反应型阻燃剂协同阻燃聚氨酯泡沫,并展望了聚氨酯泡沫阻燃剂的研究发展方向.
