摘　　要：环氧树脂是一种热固性树脂,因其具有在固化反应过程中收缩率小且黏结性、耐腐蚀性、力学性能和电绝缘性能优良等特点,广泛应用于涂料、胶粘剂、电子电器、航空航天等领域。但环氧树脂的极限氧指数仅为19.8%,在空气中易燃,这极大地限制了它的应用。9,10-二氢-9-氧杂-10-膦菲-10-氧化物(DOPO)是一种磷系阻燃剂,其分子结构中的P-H键有很高的活性,其燃烧过程中不释放有害气体,且具有阻燃性能高等优点,成为国内外研究的热点。通过近年来国内外用于阻燃环氧树脂的DOPO的相关文献,综述了DOPO环氧树脂的阻燃机理及合成方法方面的研究进展,并展望DOPO阻燃领域的研究方向。Epoxy resin is a kind of thermosetting resin.It is widely used in coatings,adhesives,electronic appliances,etc.because of its low shrinkage rate during the curing reaction,and excellent adhesion,corrosion resistance,mechanical properties and electrical insulation properties.Aerospace and other fields.However,the limiting oxygen index of epoxy resin is only 19.8%,which is flammable in the air,which greatly limits its application.9,10-dihydro-9-oxa-10-phosphinphenanthrene-10-oxide(DOPO)is a phosphorus-based flame retardant.The P-H bond in its molecular structure is highly active and burns.During the process,no harmful gas is released,and the advantages of high flame retardancy have become a hot spot in domestic and foreign research.Based on the related literature of DOPO used for flame-retardant epoxy resin in domestic and foreign data in recent years,the research progress of the flame-retardant mechanism and synthesis method of DOPO epoxy resin is reviewed,and the future research direction of DOPO flame-retardant field is made.
