Zanthoxylum bungeanum Maxim Seed Oil (ZBMSO) is widely distributed in most parts of China, which cannot be edible and extensively consumed due to its high free fatty acids. This paper reports a rational route to utilization of ZBMSO in preparation of nanocomposites which can enhance leather flame retardancy and thermal stability. ZBMSO was synthesized through three-stage process, decoloration, acid reduction and sulfitation to prepare the modified ZBMSO fatliquoring agent (MZBMSO). Then nanocomposites based on MZBMSO and stearate-layered double hydroxide (s-LDH) were prepared via in-situ method. XRD and TEM results indicated that the MZBMSO intercalate into the galleries of s-LDH with uniform dispersion. Compared with MZBMSO, the leather treated by MZBMSO/s-LDH had a remarkable improvement on flame retardancy and superior softness which limiting oxygen index (LOI) increased from 23.6% to 28.0% and smoke density index decreased from 25 to 6.
花椒籽油（ZBMSO）广泛分布于中国大部分地区，但由于其游离脂肪酸含量高，不能食用和广泛消费。本文报道了一种合理的利用 ZBMSO 制备纳米复合材料的方法，可提高皮革的阻燃性和热稳定性。通过脱色、酸还原和磺化三步法合成了改性 ZBMSO 加脂剂（MZBMSO）。然后通过原位法制备了基于 MZBMSO 和硬脂酸层状双氢氧化物（s-LDH）的纳米复合材料。XRD 和 TEM 结果表明，MZBMSO 均匀分散地插层进入 s-LDH 的层间。与 MZBMSO 相比，用 MZBMSO/s-LDH 处理的皮革的阻燃性有显著提高，柔软度也更好，极限氧指数（LOI）从 23.6%提高到 28.0%，烟雾密度指数从 25 降低到 6。
