摘要:

探讨了多羟基阳离子表面活性剂MDAE与阴离子表面活性剂直链脂肪醇聚氧乙烯醚硫酸钠(AES)复配后的性能变化,重点分析了不同配比下复配体系的界面活性、表面张力、临界胶束浓度(cmc)、润湿性和泡沫稳定性等特性。结果显示,复配后体系的cmc显著降低,表面活性和界面活性明显增强,表现出显著的协同增效作用。在较佳复配比例下(n(MDAE) ∶n(AES)=1∶9),体系展现了良好的泡沫稳定性和较强的润湿能力。研究表明,多羟基阳离子表面活性剂与AES的协同作用能显著提升表面活性和应用性能,具有广阔的工业应用前景。

Abstract:

The performance of the mixtures of a polyhydroxy cationic surfactant, MDAE, and an anionic surfactant, sodium fatty alcohol polyoxyethylene ether sulfate (AES), was studied. The interfacial activity, surface tension, critical micelle concentration (cmc), wetting ability and foam stability of the mixed system at different mixing ratios were measured. The results showed that, compared with single surfactants, the cmc of the mixed system significantly decreased, and both surface and interfacial activities were notably enhanced, indicative of significant synergistic effect. At the optimal mixing ratio (n(MDAE) ∶n(AES)=1∶9), the mixed system exhibited good foam stability and strong wetting ability. This work indicated that the synergism between MDAE and AES could significantly improve the surface activity and application performance, and the mixed system had great potential for industrial applications.

Key words: polyhydroxyl, cationic-anionic surfactant mixture, synergy, surfactant
