摘要:用氧化法合成的窄分布醇醚羧酸盐(NAEC9)与月桂醇醚硫酸铵(ALES)、十六烷基三甲基氯化铵(1631)、
八/十烷基葡糖苷(APG0810)进行复配,研究了 NAEC9 不同质量分数对复配体系表面张力、泡沫性、润湿性、
乳化性、去污性的影响。结果表明,窄分布 NAEC9 与 1631 复配后在表面张力、泡沫性、润湿、乳化性能上有
明显的协同增效作用,且 NAEC9 质量分数为 66.7%时协同作用最强,此时,润湿时间由不润湿降低至 37 s,30
s 泡沫体积最大(500 mL)。而 NAEC9 与 ALES、APG0810 复配体系在性能上协同作用不显著。在去污性能上,
NAEC9 与 ALES 复配体系对皮脂污布去污性能最好,对蛋白污布去污能力最差。阴离子表面活性剂 NAEC9 与
阳离子表面活性剂 1631 复配具有良好的协同作用,表面活性增强的同时不会产生沉淀。

Abstract: Narrow distribution alcohol ether carboxylate (NAEC9) was synthesized by oxidation. Then, it
was compounded with ammonium lauryl ether sulfate (ALES), hexadecyl trimethylammonium chloride
(1631) and octadecyl glucoside (APG0810). The effects of different mass fractions of NAEC9 on the
surface tension, foamability, wetting, emulsification and decontamination of the composite system were
studied. The results showed that the compound system of NAEC9/1631 exhibited obvious synergistic
effects on surface tension, wetting and emulsifying properties, and the synergistic effect was strongest when
the NAEC9 mass fraction was 66.7%. Meanwhile, the wetting time decreased from no wetting to 37 s, and
the foam volume reached a maximum of 500 mL at 30 s. However, no obvious synergistic effects were
found between NAEC9/ALES and NAEC9/APG0810 systems. In terms of decontamination performance,
NAEC9/ALES compound system had the best decontamination performance for sebum decontamination
cloth and the worst decontamination ability for protein decontamination cloth. The compound system of
anionic surfactant NAEC9 and cationic surfactant 1631 had a good synergistic effect, and the surface
activity enhanced without precipitating.
