摘要:Three commercialized flame retardants, 1,2-bis(diphenylphosphinoyl)ethane (EDPO), 6,6-(1,2-phenethyl)bis-6H-dibenz[c,e][1,2]oxaphosphorin-6,6-dioxide (HTP-6123), and hexa-phenoxy-cyclotriphosphazene (HPCTP), were used to prepare the flame retardant diglycidyl ether of bisphenol A (DGEBA) epoxy resin (EP) under the same experimental conditions. The effects of Tg, thermal stability, and water absorption properties of EP caused by the three flame retardants were investigated and compared, together with their flame retardant efficiency. Results showed that the introduction of the three flame retardants improved the flame retardant performance of EP but led to decreases in Tg and decomposition temperature. EDPO showed higher flame retardant efficiency than the other two flame retardants. EP/EDPO showed higher thermal stability, better flame retardant performance, higher Tg value, and lower water absorption than EP/HTP-6123 and EP/HPCTP. The study discovered that EDPO and HTP-6123 primarily act through the gas phase flame retardant mechanism, while HPCTP is primarily driven by the condensed phase mechanism. © 2020 John Wiley & Sons Ltd
