摘　　要：以C16-18混合脂肪醇聚氧乙烯醚(O-3)、二元醇及三氯氧磷为原料,制备了系列O3-n-O3(n=2,4,6,10)脂肪醇醚磷酸酯Gemini表面活性剂。用IR对制备的产物进行了结构表征,将这些系列产物的钠盐应用于绵羊皮蓝湿革的加脂工序。用扫描电镜观察了O3-4-O3型Gemini脂肪醇醚磷酸酯和普通O-3磷酸单酯加脂前后绵羊皮铬鞣胶原纤维的微观形貌变化,探讨了产物结构中联结基长度对铬鞣胶原纤维的柔软度、机械强度、透水汽性、抗静电等性能的影响规律,并与普通O-3磷酸单酯做了加脂对比实验。实验结果表明:随着联结链的增长,加脂坯革的柔软度、抗静电性都很好,基本接近,机械强度呈先递增后减弱的趋势,且均优于相应的O-3磷酸单酯;透水汽性呈减弱的下降变化趋势,略差于相应的O-3磷酸单酯;其中Gemini脂肪醇聚氧乙烯醚磷酸酯的O3-4-O3型产物的加脂效果较优。A series of O3-m-O3(m=2,4,6,10)fatty alcohol ether phosphate Gemini surfactants were prepared by C16-18 mixed fatty alcohol polyoxyethylene ether(O-3),dihydric alcohol and POCl3.The structure of the prepared products was characterized by IR,and the sodium salt of these products was applied to the fatliquoring process of sheepskin leather.The microstructure of chrome-tanned collagen fibers in sheepskin before and after fatliquoring with O3-4-O3 Gemini fatty alcohol ether phosphate and common O-3 phosphate monoester was observed by scanning electron microscope(SEM).The effects of the length of the linker in the product structure on the softness,mechanical strength,moisture permeability and antistatic properties of chrome-tanned collagen fibers were investigated,and a comparison experiment with common O-3 phosphate monoester was carried out.Experimental results show that with the increase of the link chain,the softness and antistatic properties of the fatliquoring leather fiber were very good,which were basically close to each other.The mechanical strength increased first and then decreased,and both were superior to the corresponding O-3 phosphate monoester.The water vapor permeability showed a decreasing trend,which was slightly worse than the corresponding O-3 phosphate monoester.The O3-4-O3 product of Gemini fatty alcohol polyoxyethylene ether phosphate had better fatliquoring effect.
