磷、氮膨胀型阻燃剂研究进展

Research and development of phosphorus and nitrogen containing intumescent flame retardant

综述了近年来磷、氮阻燃剂的研究新进展,并通过垂直燃烧法(UL-94)、极限氧指数(LOI)和成炭率等参数对它们的阻燃性能进行评价,并且对磷、氮阻燃剂的发展趋势进行了展望。

The recent progresses of intumescent flame retardant containing phosphorus and nitrogen were reviewed.And the flame retardant parameters such as UL-94 test,limited oxygen index（LOI）and char yields were evaluated.Finally,intumescent flame retardant containing phosphorus and nitrogen will be the future direction of development was discussion.
