摘　　要：将EO数为5的异构癸醇聚氧乙烯醚硫酸钠(1005S)与椰油酰胺丙基羟磺基甜菜碱(CHSB)以不同比例混合,对混合体系的性能进行研究,主要包括平衡表面张力、动态表面张力、乳化性能、泡沫性能和润湿性能。结果表明:对于复配体系,当CHSB与1005S以质量比5∶5进行复配时,临界胶束浓度(cmc)为9.8×10^(-3) g/L,临界胶束浓度下的表面张力(γ_(cmc))为31.7 mN/m,混合体系在乳化、润湿、泡沫性能上均优于单一组分,具有很好的协同增效作用。阴/两性离子表面活性剂复配效果优异,为环保高效的生产目标提供了科学依据。The sodium sulfate of isomeric decyl polyoxyethylene ether(1005S)with EO number 5 and co-camidopropyl hydroxy sulfobetaine(CHSB)was mixed in different proportions,and the properties of the hybrid system were studied,including equilibrium surface tension,dynamic surface tension,emulsification,foam and wettability.The results showed that for the compound system,when CHSB and 1005S were compounded with a mass ratio of 5∶5,the surface tension was 31.7 mN/m,the critical micelle concentration was 9.8×10^(-3) g/L,and the mixed system was better than the single component in emulsifying,wetting and foaming,and had a good synergistic effect.The anion/zwitterionic surfactant compound had an excellent compounding ef-fect,which provided a scientific basis for the goal of environmentally friendly and efficient production.
