【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^-6mol/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。更多还原

【Abstract】 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^-6mol/L,and the lowest surface tension( γ_cmc) is 38. 08 m N/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 hexadecyltrimethylammonium bromide（ CTAB）,and its cmc synergizes upto 2. 52%,while the γ_cmcsynergizes upto 11. 49%. BGF-10 displays a good emulsifying power for paraffin oil,as well as both thickening and defoaming performance.更多还原
