摘要：Phosphorus-containing epoxy resin was prepared from 2-diphenylphosphonothioic-1, 4-diphenol (DPO-HQ, as flame retardant). The thermal stabilities of neat epoxy resin (EP) and flame retardant modified epoxy resin (FR-EP) were studied with thermogravimetric analysis (TGA) at different heating rates. Kinetics model and model-free kinetics (MFK) were established based on TGA data. The serviceability values of model kinetics and model-free kinetics to epoxy resin and flame retardant modified epoxy resin were compared and analyzed. The initial degradation temperature of flame retardant modified epoxy resin slightly decreased with introduction of flame retardant, but the yield of char residue increased. The model kinetics of EP and FR-EP determined by using the Flynn-Wall-Ozawa method and the Coats-Redfern method were not applicable to epoxy resin system. MFK was more suitable to describe and predict the degradation behavior of epoxy resin and flame retardant modified epoxy resin.
