摘要:采用水热法在剥离蒙脱土(e-MMT)表面原位生长层状双氢氧化物(LDH),获得了复合材料 LDH@e-MMT,
将其引入到花椒籽油(ZBMSO)中制得了 LDH@e-MMT/改性花椒籽油(LDH@e-MMT/MZBMSO),通过 XRD、
FTIR、TEM 对 LDH@e-MMT/MZBMSO 进行了表征,并将 LDH@e-MMT/MZBMSO 应用于皮革加脂工艺。结
果表明,LDH@e-MMT 呈花状形貌,均匀分散在 MZBMSO 中。当 LDH@e-MMT 含量为 ZBMSO 质量的 12%
时,制备的 LDH@e-MMT/MZBMSO-3 加脂坯革具有一定的阻燃抑烟性。与 MZBMSO 加脂坯革相比,LDH@e-
MMT/MZBMSO-3 加脂坯革极限氧指数由 22.8%提升至 28.3%,有焰燃烧时间由 87 s 减少到 43 s,峰值热释放
速率降低了 44.6%,热释放总量降低了 73.3%,峰值产烟速率降低了 68.0%。

Abstract: Layered double hydroxide (LDH) was grown in situ on the surface of exfoliated montmorillonite
(e-MMT) by hydrothermal method and composite LDH@e-MMT was obtained. LDH@e-MMT was
introduced into zanthoxylum bungeanum seed oil (ZBMSO) to prepare LDH@e-MMT/modified zanthoxylum
bungeanum seed oil (LDH@e-MMT/MZBMSO). LDH@e-MMT/MZBMSO was characterized by XRD,
FTIR, and TEM. Then, LDH@e-MMT/MZBMSO was used in the leather fatliquoring process. The results
showed that LDH@e-MMT had a flower-like morphology and uniformly dispersed in MZBMSO. When
LDH@e-MMT dosage was 12% of ZBMSO mass, crust heather treated with LDH@e-MMT/MZBMSO-3
had certain flame retardancy and smoke suppression. Compared with those of MZBMSO treated crust leather,
the limited oxygen index of LDH@e-MMT/MZBMSO-3 treated crust leather increased from 22.8% to
28.3%, the flame burning time reduced from 87 s to 43 s, the peak heat release rate reduced by 44.6%, the
total heat release reduced by 73.3%, and the peak smoke production rate reduced by 68.0%.
Key words: flower-like LDH@e-MMT; in situ growth; fatliquoring; flame retardancy; smoke suppression;
