A new phosphorus-containing flame-retardant curing agent PPDTA was synthesized from phenylphosphonic dichloride (PPD) and 3-amino-1,2,4-triazole (TA) in tetrahydrofuran solvent to improve the flame retardancy of epoxy resin. The structure of the compound was analyzed and confirmed by infrared spectroscopy. The effects of reaction time, reaction temperature and ratio of reactants on yield were studied by using three-factor three-level orthogonal experiment. The results show that the yield of PPDTA can reach 86.4%, when the reaction time is 10h, reaction temperature is 70 °Cand the molar ratio of TA to PPD is 2.2:1.

AbstractA phosphorus-containing biphenyl-type phenolic resin (PBP) was prepared by dehydration polycondensation of the DOPO-disubstituted 4,4’- biphenyldimethanol compound (BDCA-2DOPO) with phenol in the presence of strong Lewis acid , in which BDCA-2DOPO was prepared by the reaction of DOPO with 4,4'-biphenyldicarboxaldehyde. The PBP resin has been evaluated as the curing agent of o-cresol epoxy resins. Experimental results indicated that the PBPcured epoxy resins exhibited good thermal stability, high char yields at 700 oC and outstanding flame retardant properties. UL 94 V-0 classifications could be obtained when the phosphorus loading in the epoxy resin is higher than 1.8 wt%.
