摘要
以含氟含氢聚硅氧烷（FPHMS）、端环氧基烯丙基聚氧乙烯醚（APEE）、三乙醇胺等为原料,经硅氢加成、环氧基氨解开环反应,制得一种新型阳离子氟硅表面活性剂（QAFS）。用IR、^1H-NMR对QAFS的结构进行了表征,并对QAFS的界面性能进行了测定。结果表明：QAFS水溶液的临界胶束浓度（cmc）为0.298 g/L,cmc处表面张力（γcmc）为27.74 m N/m;质量分数为0.5%的QAFS水溶液发泡力为1.93,5 min稳泡性为0.821;QAFS对非极性环己烷、煤油、石油醚具有较强的乳化能力,对苯的增溶力为3.0;在硬水中的稳定性为5级。
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） allyl ether （APEE） and triethanolamine （TEA）. The chemical structure of QAFS was characterized by IR and ＇H-NMR. The surface properties of QAFS were also investigated. The ex- perimental results showed that the critical micelle 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.
