【 摘 要 】

Solid polyphosphate(PBDP) was synthesized with respect to its use as additive flame retardant for epoxy resins. The influence of PBDP on the flame retardancy of epoxy resins was studied by UL-94 vertical burning test and pyrolysis combustion flow calorimetry (PCFC). With the addition of 20 wt% PBDP, the flame retardant epoxy resins pass a UL-94 V-0 level. The heat release rate, total heat release was reduced with the increased loading of PBDP. The thermal degradation kinetics results of EP and EP/PBDP composites by the Kissinger method showed that the apparent activation energy (Ea) reduced with incorporation of PBDP.
