【摘要】：為提高溫度響應(yīng)型蠕蟲膠束的抗鹽性,采用陰離子表面活性劑十八烷基苯磺酸鈉(SOBS)和兩性離子表面活性劑十八烷基羥基磺基甜菜堿(ODAHPS)制得蠕蟲膠束體系,研究了溫度對膠束黏度的影響,考察了膠束的抗鹽和抗堿性能。研究結(jié)果表明,當ODAHPS和SOBS的摩爾比為7時,膠束的響應(yīng)溫度為50℃;膠束黏度隨著溫度升高呈現(xiàn)先增加后降低的趨勢;達到響應(yīng)溫度后,膠束黏度隨表面活性劑總濃度的增加而增大;隨角頻率的增加,膠束溶液逐漸由黏性流體向彈性流體轉(zhuǎn)變;膠束黏度隨無機鹽濃度的增加先增大后降低;膠束耐堿性能良好,當弱堿和強堿質(zhì)量濃度分別為2.5 g/L和12 g/L時,膠束黏度分別為133和196 mPa·s,可以作為驅(qū)油劑使用。
[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，
