Abstract | In this work, flame-retardant benzoxazine resins were prepared by copolymerization of bisphenol A based benzoxazine (BA-a) and a phosphorous-containing phenolic derivative (DOPO-HPM). The curing behavior, thermal stability, and flame resistance of BA-a/DOPO-HPM composites were studied by differential scanning calorimeter (DSC), thermogravimetric analysis (TGA), limited oxygen index (LOI) measurement, UL94 test, and cone calorimeter. The DSC results indicated that DOPO-HPM catalyzed the curing reaction because of its acidity. The TGA results revealed that the BA-a/DOPO-HPM thermosets possessed higher decomposition temperatures (T5%) and char yields than that of BA-a. The combustion tests indicated that the flame retardant properties of BA-a/DOPO-HPM thermosets were enhanced. The BA-a/DOPO-HPM-20 sample acquired the highest LOI value of 32.6% and UL94 V-0 rating. Moreover, the average of heat release rate (av-HRR), peak of heat release rate (pk-HRR), average of effective heat of combustion (av-EHC) and total heat release (THR) of BA-a/DOPO-HPM-20 were decreased by 24.6%, 53.1%, 14.9%, and 22.1%, respectively, compared with BA-a. The attractive performance of BA-a/DOPO-HPM blends was attributed to the molecular structure of DOPO-HPM composed of DOPO group with excellent flame-retardant effect and phenolic hydroxyl group with catalysis. |
