摘　　要：分别对烷基糖苷磺基琥珀酸酯盐(APG-SS)和烷基糖苷(APG)不同摩尔比复配体系的表面张力和泡沫性能进行研究,同时研究烷基糖苷/烷基糖苷磺基琥珀酸酯盐/水三元体系的相行为。结果表明:APG-SS与APG摩尔比为2∶8时,表面张力达到27.90mN/m,cmc=0.044mmol/L,Γmax=10.86μmol/m2,Amin=0.15nm^2,与其他摩尔比复配体系相比,表面性能较好,具有较好的协同效应。在蒸馏水和硬水中,APG-SS与APG摩尔比为2∶8和4∶6的复配体系的起泡性能均优于单一表面活性剂,具有较好的协同效应。同时,复配体系的泡沫稳定性优于APG,可改善APG的抗硬水能力。APGSS/APG/H2O体系的三元相图出现胶束相、胶束-液晶共存区和双水相区。The mixtures of alkyl polyglycoside(APG)and alkyl polyglycoside sulfosuccinate(APG-SS)with different mixing ratios were studied by measuring their surface activity and foaming properties.The phase behavior of the ternary system of APG/APG-SS/H2 O was also studied.The results show that the best synergism is found in surface activity(γcmc=27.90 mN/m,cmc=0.044 mmol/L,Γmax=10.86μmol/m2,Amin=0.15 nm^2)when nAPG-SS∶nAPG=2∶8.The mixed system has higher foaming ability in distilled water and hard water than single surfactant when nAPG-SS∶nAPG=2∶8 and 4∶6,so it has synergism.At the same time,the foam stability of the mixed system is better than APG,which can improve the hard water resistance of APG.The phase diagrams of the APG-SS/APG/H2 O ternary systems were characterized by micellar phase,a region where lamellar liquid crystal and micellar phases coexisted and a region of"aqueous two-phase".
