摘要
近年来,出于环保等方面的考虑,一些卤系阻燃剂被逐渐淘汰,磷系阻燃剂作为卤系阻燃剂的替代品备受关注。然而,高效的磷系阻燃剂通常会在提高阻燃性能的同时产生更多的烟雾,因此需要与协效剂搭配使用。本文介绍了磷系阻燃剂在环氧树脂中的阻燃机理,综述了环氧树脂中磷系阻燃剂的协效体系的研究进展,包括无机协效剂、有机协效剂及有机-无机杂化协效剂等,并对环氧树脂体系中磷系阻燃剂的协效体系的未来发展趋势进行了展望。
In recent years,some halogen-based flame retardants have been gradually eliminated out for consideration of the environment,and phosphorus-containing flame retardants have received extensive attention as substitutes for halogen-based flame retardants.However,efficient phosphorus-based flame retardants usually produce more smoke while improving flame retardancy,therefore,they need to be used in combination with synergists.This paper introduced the flame-retardant mechanism of phosphorus-containing flame retardants in epoxy resin.The latest research progress of synergists,including inorganic,organic,and organic-inorganic hybrid synergistic agents,with phosphorus-based flame retardants in epoxy resin was summarized.We look forward to the future development trend of the synergistic system of phosphorus-containing flame retardants in epoxy resin.
