摘要： 以醇醚糖苷AEG050为原料,研究了其自身表面性能及不同添加剂对其表面性能的影响。结果表明,在25 ℃下AEG050的临界胶束浓度cmc=44.5 mg/L,最低表面张力γcmc=29.4 mN/m,具有较强的抗硬水能力。随着NaCl和Na2SO4两种无机盐浓度的增加,AEG050的表面活性增强。在较低浓度的一元醇溶液中,AEG050的表面活性增强,但当醇浓度较高时,其表面活性下降。AEG050与其他表面活性剂复配有一定的增效作用,尤其是与十六烷基三甲基溴化铵形成的复配体系,其cmc增效34.2%,γcmc增效4.1%。

Abstract: Surface performance of alkyl ethoxy polyglycosides (AEG050) and the influences of different additives on them were examined.Results showed that:at 25 ℃,the value of critical micelle concentration (cmc) achieves 44.5 mg/L,and the surface tension at cmc (γcmc) achieves 29.4 mN/m.Besides,it displays rather strong capacity for resistance to hard water.With the increase of concentration of NaCl and/or Na2SO4,their surface activity increases.In monohydric alcohol solution of relatively lower concentration,the surface activity of AEG050 also strengthens,but when the monohydric alcohol concentration is relatively higher,their surface activity declines.There is a certain synergetic effect when AEG050 blends with other surfactants,especially cetyltrimethylammonium bromide (CTAB).In this case,cmc of blend composed of AEG050 and CTAB synergizes as 34.2% lower,while the surface tension γcmc decreases 4.1%.

Key words: alkyl ethoxy polyglycosides, additive, critical micelle concentration, surface tension, blend
