摘要
分别利用凝胶色谱仪、表面张力仪和激光粒度仪表征了聚醚-聚丙烯酸/酯高分子表面活性剂HS-PA的分子量、表面张力以及胶束聚集体的粒径分布。并考察了HS-PA在分别以LAS/AES/AEO_(9)为主表面活性剂的非结构型/结构型洗涤剂中的增稠性能、去污性能、液晶形态、悬浮性能以及流变行为。性能表征结果表明:HS-PA的重均分子量为4244,临界胶束浓度为3×10^(-7)mol/L,平衡表面张力为42.06 mN/m;当HS-PA分别与LAS、AES、AEO_(9)形成混合胶束时,聚集体的平均粒径增大;在非结构型洗涤剂中的应用测试结果表明:HS-PA对LAS/AES/AEO_(9)为主表面活性剂的配方均有提升黏度的作用,同时有利于改善洗涤剂在JB03皮脂污布上的去污力;在结构型洗涤剂中的应用测试结果说明:HS-PA将有助于LAS/AES/AEO_(9)体系形成球形层状液晶,且HS-PA用量越多,AES体系的液晶数量越多;离心结果表明,含HS-PA的结构型洗涤剂具有稳定悬浮微胶囊的能力;经旋转流变仪测定,HS-PA可提高LAS配方体系的屈服应力。
The molecular weight,surface tension,and the particle size distribution of micellar aggregates of a polyetherpolyacrylate polymeric surfactant,HS-PA,were characterized on gel permeation chromatograph,surface tension meter,and laser particle size analyzer,respectively.The thickening properties,detergency,liquid crystal morphology,suspension properties,and rheological behaviors of HS-PA in unstructured/structured detergents with LAS/AES/AEO_(9) as the main surfactants,respectively,were also investigated.The characterization results showed that,the weight-average molecular weight of HS-PA was 4244,the critical micelle concentration was 3×10^(-7)mol/L,and the equilibrium surface tension was 42.06 mN/m;the average particle size of aggregates was increased when LAS,AES and AEO_(9) formed mixed micelles with HS-PA,respectively.The application test in unstructured detergents showed that,HS-PA had viscosityenhancing effects on all the LAS/AES/AEO_(9)-based systems,and meanwhile it was beneficial to the improvement of the detergency to sebum.The application test in structured detergents showed that,HS-PA would help the formation of lamellar liquid crystals in the LAS/AES/AEO_(9) systems,and the more HS-PA used,the more the liquid crystals in the AES system;the centrifugal separation results showed that the structured detergents containing HS-PA had the ability to stabilize the suspension of microcapsules;HS-PA could increase the yield stress of the LAS formulation system as determined by rotational rheometer.
