A biobased flame retardant, trieugenylphosphate (TEP), was synthesized from eugenol and incorporated at concentrations of 10 and 30 wt.% into the epoxy matrix. Flammability and thermal stability were investigated using the UL-94 test, pyrolysis-combustion flow calorimetry (PCFC), and thermogravimetric analysis (TGA). Thermal and thermomechanical properties were examined by differential scanning calorimetry (DSC) and dynamical mechanical thermal analysis (DMTA). The modified resin with TEP content showed self-extinguishing properties and acceptable thermal and thermomechanical properties. Furthermore, the microcalorimetric method proved that the introduction of the TEP additive to the epoxy matrix reduced the values of pHRR (414.4 ± 5.5 W/g), THR (29.1 ± 0.6 kJ/g), and HRC (446 ± 7 J/g·K) for the sample tested compared to the unmodified resin.
一种生物基阻燃剂——三丁香酚磷酸酯（TEP），由丁香酚合成，并以10 wt.%和30 wt.%的浓度加入到环氧基体中。采用UL-94测试、热解燃烧流动量热法（PCFC）和热重分析（TGA）研究了其燃烧性能和热稳定性。通过差示扫描量热法（DSC）和动态热机械分析（DMTA）考察了其热性能和热机械性能。含TEP的改性树脂表现出自熄性能以及可接受的热性能和热机械性能。此外，微量量热法证明，与未改性树脂相比，向环氧基体中引入TEP添加剂降低了测试样品的热释放速率峰值（pHRR）（414.4±5.5 W/g）、热释放总量（THR）（29.1±0.6 kJ/g）和热释放能力（HRC）（446±7 J/g·K）。
