【摘要】：为提高温度响应型蠕虫胶束的抗盐性,采用阴离子表面活性剂十八烷基苯磺酸钠(SOBS)和两性离子表面活性剂十八烷基羟基磺基甜菜碱(ODAHPS)制得蠕虫胶束体系,研究了温度对胶束黏度的影响,考察了胶束的抗盐和抗碱性能。研究结果表明,当ODAHPS和SOBS的摩尔比为7时,胶束的响应温度为50℃;胶束黏度随着温度升高呈现先增加后降低的趋势;达到响应温度后,胶束黏度随表面活性剂总浓度的增加而增大;随角频率的增加,胶束溶液逐渐由黏性流体向弹性流体转变;胶束黏度随无机盐浓度的增加先增大后降低;胶束耐碱性能良好,当弱碱和强碱质量浓度分别为2.5 g/L和12 g/L时,胶束黏度分别为133和196 mPa·s,可以作为驱油剂使用。
[Abstract]:In order to improve the salt resistance of temperature-responsive worm micelles, the anionic surfactant sodium octadecylbenzene sulfonate (SOBS) and the amphoteric surfactant octadecyl hydroxy sulfonylbetaine (ODAHPS) were used to prepare the worm micelle system. The effect of temperature on micelle viscosity was studied, and the salt resistance and alkali resistance of micelles were investigated. The results show that when the molar ratio of ODAHPS to SOBS is 7, the micelle response temperature is 50 鈩，
