反应型DOPO基阻燃剂在环氧树脂中的应用

Applications of reactive-type DOPO based flame retardant in epoxy resins

综述了近年来在反应型DOPO基(9,10-二氢-9-氧-10-磷杂菲-10-氧化物)阻燃剂中引入羟基、羧基、氨基等基团以及与氰酸酯加成得到具有阻燃性的环氧树脂固化剂以及在DOPO衍生物中引入环氧基,制备本质阻燃环氧树脂的研究进展。

The flame retardant epoxy curing agent could be obtained by introducing hydroxy, carboxy or amino groups to 9, 10 - dihydro - 9 - oxy - 10 - phosphaphenanthrene - 10 - oxide（DOPO） or by the addition reaction of cyanate ester with DOPO. The inherent flame retardant epoxy resin could be prepared by introducing epoxy groups to DOPO derivatives. The research progress of above mothods was reviewed.
