| 摘要: |
| 实验选用椰油酰羟乙基磺酸酯钠（SCI- 85）作为主表面活性剂，分别与月桂酰肌氨酸钠（LS-30）、月桂醇醚磺基琥珀酸单酯二钠盐（MES）、α-烯基磺酸钠（AOS）、月桂醇醚磷酸酯钾盐（MAP）辅助表面活性剂按一定比例进行复配以制得温和表面活性剂体系。通过考察体系的起泡性、稳泡性、稳态流变性质和动态流变性质等研究了SCI- 85在表面活性剂体系中的应用。结果表明，SCI-85复配MES的体系发泡能力最强，复配LS-30的体系发泡能力最弱；SCI- 85复配MES的体系稳泡性能最好，复配AOS的体系稳泡性能最差；4种辅助表面活性剂对SCI- 85体系抗剪切能力的提高程度比较来看，LS-30的提高程度最大；4个体系在一定的振荡频率范围内结构均比较稳定。 |

| Abstract: |
| Sodium cocoyl isethionate (SCI-85) was chosen as the main surfactant, which was mixed with co-surfactants such as sodium lauroyl sarcosine (LS-30), disodium laureth sulfosuccinate (MES), alpha olefin sulfonate (AOS) and potassiam polyoxyethylene
laurylether phosphate (MAP) according to a certain ratio to prepare a mild surfactant system. The properties of this system were examined, including the foaming power, foam stability, and steady-state and dynamic rheological properties. The results showed that the foaming ability was strongest for the system of SCI-85 mixed with MES, but the weakest when mixed with LS-30; the foam stability was the best for the system of SCI-85 mixed with MES, but the worst when mixed with AOS; LS-30 had the most significant enhancement in the anti-shearing ability upon the system of SCI-85 among the four co-surfactants; Within a suitable frequency range, all these four systems had steady structure. |
