The self-thickening agent (TZXJ) consisting of acrylamide (AM), 1-carboxy-N, N′-dimethyl-N-(3-methyl-acrylamidopropyl) ethanaminium (CBMAA-1), [2-(Methacryloyloxy)ethyl]trimethylammonium chloride (DMC) and N, N′-dimethyl octadecyl allyl ammonium chloride (DOAC) was synthesized and characterized. Effects of two kinds of surfactants 2-(bis(2-hydroxyethyl)(octadecyl)ammonio)acetate (ODB) and N,N,N-trimethyloctadecan-1-aminium bromide (STAB) on thickening performance, temperature resistance and shear resistance of TZXJ acid solution were studied via six-speed rotational viscometer and HAAK MARSⅢ Rheometer. Results showed that the ODB and STAB as accelerators can greatly enhance the thickening ability and temperature resistance of TZXJ self-thickening acid. After TZXJ self-thickening spent acid with accelerators was sheared at 140 °C for 60 min, the apparent viscosity of spent acid can reach 204 mPa s. It was found that the research results provided a new research idea that a small amount of long-chain cationic or amphoteric surfactants may greatly improve the application performance of hydrophobic associative polymeric self-thickening acid.

自增稠剂（TZXJ），由丙烯酰胺（AM），1-羧基-N，N'-二甲基-N-（3-甲基-丙烯酰胺基丙基）乙铵（CBMAA-1），[2-（甲基丙烯酰氧基）乙基]组成合成并表征了三甲基氯化铵（DMC）和N，N'-二甲基十八烷基烯丙基氯化铵（DOAC）。两种表面活性剂2-（双（2-羟乙基）（十八烷基）铵）乙酸盐（ODB）和N，N，N-三甲基十八烷基-1-溴化铵（STAB）对增稠性能，耐热性和抗剪切性的影响用六速旋转粘度计和HAAKMARSⅢ流变仪研究了TZXJ酸溶液。结果表明，ODB和STAB作为促进剂可以大大增强TZXJ自增稠酸的增稠能力和耐热性。用促进剂将TZXJ自增稠的废酸在140°C剪切60分钟后，废酸的表观粘度可达到204 mPa s。发现该研究结果提供了新的研究思路，即少量的长链阳离子或两性表面活性剂可以大大改善疏水缔合聚合物自增稠酸的应用性能。
