摘要:

磷杂菲（DOPO）类衍生物是一类典型的无卤有机磷阻燃剂，在气相和凝聚相中均能显示优异的阻燃效果，可以提高高分子材料的阻燃性能，是目前研究的热点之一。本文介绍了磷杂菲类阻燃剂的特点、阻燃机理、合成方法以及近十年来在热塑性树脂（聚酰胺、聚碳酸酯、聚氨酯、ABS树脂和聚乳酸）和热固性树脂（环氧树脂和不饱和聚酯树脂）中的应用进展。最后指出阻燃剂未来发展的趋势有以下几点：设计高阻燃性能的分子；建立高效的合成方法；具有优异的机械性能。

Abstract:

Phosphaphenanthrene (DOPO) derivatives were a kind of typical halogen-free organophosphorus flame retardants, which were also one of the research hotspots, exhibiting excellent flame retardant effect in both gaseous-phase and condensed-phase and improving the flame retardant performance of polymer materials. The characteristics, flame retardant mechanism, synthetic and application of phos-phaphe-nanthrene derivatives were described in thermoplastic resins (polyamide, polycarbonate, polyure-thane, ABS resin and polylactic acid) and thermosetting resins (epoxy resins and unsaturated polyester resin) in the past decade. Finally, the development trends of flame retardants were pointed out as follows: design of the molecules with high flame retardant performance; establish efficient synthesis method; pos-sess excellent mechanical properties.
