腰果酚聚氧乙烯醚的表面性能研究
Study on the surface performance of cardanol polyoxyethylene ether
摘要
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 -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 hexadecyltrimethylammonium bromide (CTAB),and its cmc synergizes upto 2. 52%,while the γcmc synergizes upto 11. 49%. BGF -10 displays a good emulsifying power for paraffin oil,as well as both thickening and defoaming performance.关键词
