High flammability has always been a limiting factor for leather products. Herein, a new strategy that chose zanthoxylum bungeanum seed oil(ZBMSO) and aqueous miscible organic solvent treatment(AMOST) modified layered double hydroxide(O-LDH) were used to prepare flame retardant leather in this work. Firstly, O-LDH was prepared through acetone organic modified layered double hydroxide led to a better dispersion, then the modified zanthoxylum bungeanum seed oil(MZBMSO)/O-LDH composites was obtained by used O-LDH and MZBMSO through in-situ method. Finally, MZBMSO/O-LDH composites were applied to the leather fatliquoring processing, and tested the flame retardant of leather. The thermal stability of leather was effectively improved with composites, and the combustible gas released during thermal decomposition of leather decreases obviously. Limit oxygen index(LOI) value of leather reached 28.3%, the smoke density value dropped 68% to 9.28%/min. The dispersion of LDH was improved by a simple aqueous miscible organic solvent treatment method and prepared the leather with excellent flame retardant, it reduced the release of toxic gases and improved the safety of leather products.

高易燃性一直是皮革产品的限制因素。本文采用花椒种子油（ZBMSO）和水溶性有机溶剂处理（AMOST）改性层状双氢氧化物（O-LDH）的新策略制备阻燃皮革。首先通过丙酮有机改性层状双氢氧化物制备O-LDH，使其分散性更好，然后通过原位制备方法将O-LDH和MZBMSO分别用于改性花椒种子油（MZBMSO）/ O-LDH复合材料。最后，将MZBMSO / O-LDH复合材料应用于皮革加脂工艺，并测试了皮革的阻燃性。复合材料有效改善了皮革的热稳定性，皮革热分解过程中释放的可燃气体明显减少。皮革的极限氧指数（LOI）值达到28.3％，烟气密度值下降68％至9.28％/ min。通过简单的水溶性有机溶剂处理方法改善了LDH的分散性，并制备了具有优异阻燃性的皮革，减少了有毒气体的释放，提高了皮革产品的安全性。
