以2-二苯基膦酰基-1,4-苯二酚(DPO-HQ)为阻燃剂制备了阻燃环氧树脂，利用动态热重分析法（TGA）研究了纯环氧树脂（EP）和阻燃环氧树脂（FR-EP）在不同升温速率下的热稳定性，建立了EP和FR-EP体系的动力学模型和非模型动力学（MFK），并对比分析了模型动力学和非模型动力学对于描述 EP 体系和 FR-EP 体系的适用性。结果表明：阻燃剂的引入降低了环氧树脂初始降解温度，但增加了残炭率。由 Flynn-Wall-Ozawa 方法和Coats-Redfern方法建立的模型动力学表征EP和FR-EP体系高温降解过程中误差较大，而非模型动力学能更准确地预测和描述EP和FR-EP体系的高温降解行为。

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.
