摘要：研究了腰果酚聚氧乙烯醚BGF-10的表面活性及不同添加剂对其表面活性的影响。结果表明,在25℃时BGF-10的临界胶束浓度cmc=6.09×10^(-6)mol/L,最低表面张力γ_(cmc)=38.08 m N/m,具有较好的抗硬水能力。BGF-10对一价的无机盐具有较强的抗盐性,随着二价无机盐浓度的增加,BGF-10的表面活性增强。一元醇能够降低BGF-10的表面张力,随着一元醇浓度的增加,BGF-10形成胶束的能力先升高后降低。BGF-10与表面活性剂复配具有一定的增效作用,尤其是与十六烷基三甲基溴化铵(CTAB)形成的复配体系,其cmc增效2.52%,γ_(cmc)增效11.49%。BGF-10对液体石蜡的乳化能力好,且具有增稠和低泡的性能。
Surface activity of cardanol polyoxyethylene ether BGF - 10 and the effects of different additives on the surface activity were studied. Results show that the critical micelle concentration （cmc） of BGF - 10 is 6.09 ×10^-6 mol/L, and the lowest surface tension （ γcmc ） is 38.08 mN/m at 25 ℃. Moreover, BGF - 10 displays a better resistance to hard water and a strong salt tolerance to monovalent inorganic salts. With the increase of concentration of divalent inorganic salt, the surface activity of BGF - 10 is enhanced. Monohydric alcohol can reduce the surface tension of BGF - 10. The ability of BGF - 10 to form micelles increases in the beginning and then decreases with the increase of monohydric alcohol concentration. BGF - 10 displays a synergistic effect with other surfactants, especially with hexadecyhrimethylammonium bromide （ CTAB）, and its cmc synergizes upto 2. 52% ,while the Tome synergizes upto 11.49%. BGF - 10 displays a good emulsifying power for paraffin oil, as well as both thickening and defoaming performance.
