皮革防水加脂剂的活性组分结构与其防水性相关性的研究

STUDY ON THE RELATIONSHIP BETWEEN THE STRUCTURE OF THE ACTIVE COMPONENTS OF FATLIQUORING AGENTS AND THE WATER-PROOFNESS OF LEATHER

合成了脂肪醇磷酸酯盐、脂肪醇琥珀酸单酯磺酸钠盐和脂肪胺琥珀酸单酰胺磺酸钠盐3个系列皮革防水加脂剂常用的表面活性剂组分,通过加脂应用实验,比较了不同碳链长度的活性成份对皮革的防水性能的影响。结果表明,脂肪胺的碳链越长,脂肪胺琥珀酸单酰胺磺酸钠盐在皮革加脂中的防水性能越好;当脂肪醇为十六醇时,脂肪醇磷酸酯盐和脂肪醇琥珀酸单酯磺酸钠盐在皮革加脂中的防水性能最好。

The active components in the fatty alcohol phosphates, ether sulfosuccinates and amidated ether sulfosuccinates series leather/atiliquoring agent are synthesized. The water proof properties of three active components with different carbon chain length are compared in the experiments. The result shows that when the carbon chain is longer, the waterproof property of amidated ether sulfosuccinates is better. When the carbon number is 16, the waterproof property of fatty alcohol phosphates and ether sulfosuccinates is the best.
