Nanocomposite technology is the most promising strategy to synchronously improve the mechanical properties and flame retardancy of polymer materials. In this study, zirconium aminotrimethylene phosphonate (ZrATMP) nanorods were synthesized from amino tris(methylene phosphonic acid) and added to epoxy resin (EP) to further prepare ZrATMP-EP composites. Compared with those of pure EP, the peak heat release rate, total heat release, total smoke release, and peak CO production rate of the 3 wt% ZrATMP-EP composite decreased by 30.4 %, 39.2 %, 23.1 %, and 47.3 %, respectively. This was because Lewis acid sites on the ZrATMP nanorods catalyzed the carbonization of the EP matrix to form a dense protective char layer. Additionally, the tensile and impact strengths of 3 wt% ZrATMP-EP were 110.7 % and 75.5 % greater than those of pure EP, respectively. ZrATMP nanorods are a new class of flame retardant additive because of the simultaneous improvements in fire safety and mechanical strength of polymers.

纳米复合材料技术是同步提高高分子材料力学性能和阻燃性能最有前景的策略。本研究以氨基三亚甲基膦酸为原料合成了氨基三亚甲基膦酸锆（ZrATMP）纳米棒，并将其添加到环氧树脂（EP）中进一步制备了ZrATMP-EP复合材料。与纯EP相比，3 wt% ZrATMP-EP复合材料的峰值放热率、总放热量、总发烟量和峰值CO生成率分别降低了30.4%、39.2%、23.1%和47.3%。分别。这是因为 ZrATMP 纳米棒上的路易斯酸位点催化了 EP 基质的碳化，形成致密的保护炭层。此外，3 wt% ZrATMP-EP 的拉伸强度和冲击强度分别比纯 EP 高 110.7% 和 75.5%。 ZrATMP纳米棒是一类新型阻燃添加剂，因为它同时提高了聚合物的防火安全性和机械强度。
