The zirconium-based metal–organic framework material (UiO-66-NH₂) was synthesized by solvothermal method, and its excellent adsorption performance was used to combine it with the phosphorus-based flame retardant triethyl phosphate (TEP) and to improve the flame retardant and smoke suppression properties of epoxy resin (EP). The morphology, chemical composition, and structure of the synthesized flame retardant were analyzed by scanning electron microscope, energy dispersion spectrum, Fourier transform infrared spectroscopy, and x-ray diffractometer. The cone calorimeter measurement of EP composite materials shows that EP composite materials have good flame retardant and smoke suppression properties. Compared with EP, after the UiO-66-NH₂ flame retardant which adsorbs TEP is added, the peak heat release rate, total heat release, peak smoke release rate, total smoke production, carbon monoxide release rate, and carbon dioxide release rate of EP composites have been reduced. From the results of thermal analysis and scanning electron microscope, it can be seen that the synthesized flame retardant can act both in the condensed phase and in the gas phase. Thereby, the combustion of the matrix and the diffusion of the toxic gas, smoke and heat generated during the combustion are inhibited, and the flame retardant and smoke suppression effects are achieved.

UiO-66-NH2吸附磷酸三乙酯的制备及表征：环氧树脂的阻燃抑烟性能

采用溶剂热法合成了锆基金属有机骨架材料(UiO-66-NH 2 )，利用其优异的吸附性能，将其与磷系阻燃剂磷酸三乙酯(TEP)复合，提高了阻燃剂的阻燃性能_。环氧树脂（EP）的阻燃和抑烟性能。利用扫描电子显微镜、能谱、傅里叶变换红外光谱和X射线衍射仪对合成阻燃剂的形貌、化学组成和结构进行了分析。EP复合材料的锥形量热仪测量表明EP复合材料具有良好的阻燃、抑烟性能。与EP相比，添加吸附TEP的UiO-66-NH ₂阻燃剂后，其峰值放热率、总放热量、峰值发烟率、总发烟量、一氧化碳释放率、二氧化碳释放率EP复合材料已减少。从热分析和扫描电镜结果可以看出，合成的阻燃剂既能在凝聚相中发挥作用，又能在气相中发挥作用。从而抑制基体的燃烧以及燃烧时产生的有毒气体、烟雾和热量的扩散，达到阻燃、抑烟的效果。
