Aluminum phosphates coated sepiolite nanocomposite was fabricated via a simple one-pot heterogeneous precipitation strategy, and the effects of aluminum phosphates on the morphology of aluminum phosphates coated sepiolite were investigated. Moreover, the effect of aluminum phosphates coated sepiolite on the flame-retardant behavior, mechanical properties, and thermal stability of epoxy resin have been discussed. The results indicated that the introduction of only 20 wt% aluminum phosphates coated sepiolite in epoxy resin increased the limited oxygen index from 21.8% to 30.1%, thus the material met the UL-94 V-0 rating. Thermogravimetric analyses revealed that char yield increased in the presence of aluminum phosphates coated sepiolite form thermally stable carbonaceous char. Aluminum phosphates–coated sepiolite could improve the mechanical performance, thermal stability of epoxy resin.

磷酸铝包覆海泡石在环氧树脂中的阻燃性能

通过简单的一锅异相沉淀策略制备了磷酸铝包覆的海泡石纳米复合材料，并研究了磷酸铝对磷酸铝包覆海泡石形貌的影响。此外，还讨论了磷酸铝包覆海泡石对环氧树脂阻燃性能、机械性能和热稳定性的影响。结果表明，在环氧树脂中仅引入 20 wt% 的磷酸铝包覆海泡石将极限氧指数从 21.8% 提高到 30.1%，从而使材料达到 UL-94 V-0 等级。热重分析表明，在磷酸铝包覆的海泡石形成热稳定碳质炭的情况下，炭产率增加。
