摘要
Abstract
The novel cationic fluorosilicone surfactants (QAFS) was prepared by hydrosilylation and epoxy ammonia ring- opening reaction from fluorine- containing and hydrogen- containing polysiloxane (FPHMS), ep⁃oxy- terminated poly(ethylene oxide) al yl ether (APEE) and triethanolamine (TEA). The chemical structure of QAFS was characterized by IR and 1H- NMR. The surface properties of QAFS were also investigated. The ex⁃perimental results showed that the critical micel e concentration (cmc) of 0.5% QAFS aqueous solution was 0.298 g/L. The surface tension (γcmc) at cmc was 27.74 mN/m. The foaming power of 0.5% QAFS (mass frac⁃tion) aqueous solution was 1.93 and foam stability after 5 min was 0.821. The emulsifying capacity of 0.5%QAFS solution was strong for non- polar solvent cyclohexane, kerosene and petroleum ether. The solubilizing capacity of 0.5%QAFS solution for benzene was 3.0. The stability of QAFS in hard water was grade 5.关键词
