The fabrication of engineering plastics combining high efficiency flame retardancy and thermal resistance are essential for practical applications. A novel halogen-free binary hybrid with lamellar and porous structure, Zr-BDC@CeHPP, was created by hydrothermal reaction, thereafter blended with polycarbonate (PC) to improve its thermostability and fire safety. With 2 wt% Zr-BDC@CeHPP, temperatures under peak decomposition rates (T_max1 and T_max2) of PC were increased by 28 and 34 °C under oxidizing atmosphere. Time to reach PHRR (t-PHRR) and time to ignition (TTI) and of PC were effectively prolonged to 145 and 18 s, respectively. In comparison with pure PC, the peak of heat release rate (PHRR), total heat release (THR), peak specific extinction area (PSEA) and total smoke release (TSR) of PC composites were reduced by 45%, 20%, 74% and 18%, respectively. Moreover, the flame retardant PC reached V-0 rating in UL-94 vertical burning test. The results indicated that the hybrid was able to fully utilize the advantages of Zr-BDC and CeHPP. In the ignition and middle periods of combustion, Zr-BDC@CeHPP played roles in delaying and suppressing explosive combustion. In severe combustion stage, Zr-BDC@CeHPP could catalyze the char-forming process and serve as a barrier.

结合高效阻燃性和耐热性的工程塑料的制造对于实际应用至关重要。通过水热反应制备了一种新型的层状多孔结构的无卤素二元杂化体Zr-BDC @ CeHPP，然后与聚碳酸酯（PC）混合以提高其热稳定性和防火性。使用2 wt％Zr-BDC @ CeHPP时，温度处于峰值分解速率（T _max1和T _max2在氧化气氛下PC的）升高了28和34°C。达到PHRR的时间（t-PHRR）和点燃时间（TTI）和PC的有效时间分别延长至145和18 s。与纯PC相比，PC复合材料的放热率（PHRR），总放热（THR），峰值比消光面积（PSEA）和总烟气释放（TSR）的峰值分别降低了45％，20％，74 ％和18％。此外，阻燃PC在UL-94垂直燃烧测试中达到V-0等级。结果表明，该杂种能够充分利用Zr-BDC和CeHPP的优势。在点火和燃烧中期，Zr-BDC @ CeHPP在延迟和抑制爆炸性燃烧中发挥了作用。在严重燃烧阶段，Zr-BDC @ CeHPP可以催化焦炭形成过程并起到屏障作用。
