摘要:以六水合三氯化铁(FeCl 3 ·6H 2 O)与对苯二甲酸(H 2 BDC)为原料,通过溶剂热法制备了以 H 2 BDC 为配
体的铁基有机骨架化合物(MIL-53-Fe)。当以皮质量 3%铬粉(以 Cr 2 O 3 质量计为皮质量的 0.75%)与皮质量 2%
超声后的 MIL-53-Fe 对酸皮进行结合鞣制时,鞣制后皮革收缩温度(T s )达到 101.8 ℃,与实验中纯铬鞣制皮革
相比减少了铬鞣剂用量 40%,鞣制后的皮革增厚率达到 18.1%,抗张强度为 29.56 MPa,断裂伸长率为 89.77%,
耐水洗性好,铬鞣剂的吸收率较高。将 MIL-53-Fe 进行单独鞣革,鞣制后皮革收缩温度为 72.5 ℃,T s 相比于酸
皮有所提高,表现出鞣性。结果表明,MIL-53-Fe 可与铬鞣剂进行结合鞣制,能够促进铬鞣剂的吸收,提高成
革耐水洗性。

Abstract: Fe-based metal organic framework (MIL-53-Fe) was prepared by solvent thermal method using
FeCl 3·6H 2O and terephthalic acid (H 2BDC) as raw materials. When the dosage of chrome tanning agent
was 3% acid leather weight (as for Cr 2O 3 is 0.75%), dosage of ultrasonic MIL-53-Fe was 2% acid leather
weight, the shrinkage temperature (T s) of tanned leather reached 101.8 ℃, reducing the dosage of chrome
tanning agent 40%, tanned leather thickening rate reached 18.1%, the tensile strength reached 29.56 MPa,
the elongation at break was 89.77%, the tanned leather performed a good washing durability and high
absorption rate of chrome tanning agent. The shrinkage temperature of MIL-53-Fe tanned leather reached
72.5 ℃, which showed a certain improvement compared with that of the acid skin, indicating that
MIL-53-Fe had some tanning. The results showed that MIL-53-Fe can be used with chrome tanning agent,
which can promote the absorption of chrome tanning agent and improve the washing durability of leather.
