The issue of hazardous smoke and toxic gases released from epoxy resins (EP), which often causes casualties in real fires, has limited its application. Therefore, we have developed a novel flame retardant based on a bimetallic-doped phytate-melamine (BPM) structure with Zn and Fe ions incorporated into the polymer matrix using a straightforward solution-based synthetic method. The combustion performance of the composite was evaluated using a cone calorimeter test, which showed that the peak heat release, total heat release, and total smoke production were reduced by 50%, 31.7%, and 29.2%, respectively, compared to those of EP. Additionally, the fire growth index was noticeably reduced by 60% owing to the synergistic catalytic effect of the bimetallic ions, and the high nitrogen and phosphorus content of the additives. Overall, this study provides new insights into the application of bimetallic doping for flame retardant polymer composites.
环氧树脂（EP）释放的有害烟雾和有毒气体问题在实际火灾中常导致人员伤亡，这限制了其应用。因此，我们开发了一种基于双金属掺杂植酸盐 - 三聚氰胺（BPM）结构的新型阻燃剂，通过简单的溶液合成方法将锌和铁离子引入聚合物基体。使用锥形量热仪测试评估了复合材料的燃烧性能，结果表明，与EP相比，峰值热释放、总热释放和总烟雾产生量分别降低了50%、31.7%和29.2%。此外，由于双金属离子的协同催化作用以及添加剂中高含量的氮和磷，火灾增长指数显著降低了60%。总体而言，本研究为双金属掺杂在阻燃聚合物复合材料中的应用提供了新的见解。
