Abstract

This paper developed a rare-earth metal–organic framework (MOF) flame retardant and applied it to epoxy resin (EP). This process utilized hexa (4-carboxyphenoxy) cyclotriphosphazene as the organic ligand and yttrium nitrate hexahydrate as the rare-earth metal source to prepare a novel Yttrium-based MOF (Y-MOF) via a solvothermal method. The Y-MOF synthesized under optimal conditions was characterized using scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FT-IR). Thermogravimetric Analysis (TGA) and cone calorimetry (CCT) results indicate EP-1 exhibits excellent thermal stability with a high char residue of 12.25%. Concurrently, EP-1 reduces peak heat release rate (PHRR) and total heat release (THR) by 51.56% and 26.23%, respectively. Total smoke production (TSP) decreased by 10.23%, while peak CO production rate (PCOP) and peak CO₂ production rate (PCO₂P) decreased by 55.26% and 55.43%, respectively. The tensile strength and impact strength are 3.49% and 19.32% higher than those of pure EP, respectively.

含磷腈环的新型钇基MOF的制备及其在EP中的应用

研制了一种稀土金属有机骨架阻燃剂，并将其应用于环氧树脂。本工艺以六（4-羧基苯氧基）环三磷腈为有机配体，以六水硝酸钇为稀土金属源，通过溶剂热法制备了一种新型的钇基MOF （Y-MOF）。利用扫描电镜（SEM）和傅里叶变换红外光谱（FT-IR）对最佳条件下合成的Y-MOF进行了表征。热重分析（TGA）和锥量热分析（CCT）结果表明，EP-1具有良好的热稳定性，炭残量高达12.25%。同时，EP-1使峰值放热率（PHRR）和总放热率（THR）分别降低51.56%和26.23%。总产烟量（TSP）下降了10.23%，CO产率峰值（PCOP）和CO2产率峰值（PCO2P）分别下降了55.26%和55.43%。与纯EP相比，拉伸强度和冲击强度分别提高3.49%和19.32%。
