以α,ω-含氢硅油(α,ω-PHMS)和烯丙基环氧基聚醚(APEE)为原料,无水乙醇为溶剂,在铂催化下,通过硅氢加成合成环氧基聚醚聚硅氧烷(EPEPS),再与N,N-二甲基十二烷基叔胺(DMA12)进行开环反应,制得一种新型季铵盐型有机硅双子表面活性剂(QSGS).用红外光谱(IR)对QSGS和EPEPS的结构进行了表征,并对QSGS的临界胶束浓度(cmc)、表面张力、发泡力、耐酸碱盐稳定性和在硬水中的稳定性等进行了测定.结果表明:QSGS水溶液的cmc为1.6 g/L,cmc处表面张力(γcmc)为25.5 mN/m.质量分数为0.5%的QSGS水溶液发泡力为1.63,5 min稳泡性为0.158,在硬水中的稳定性为5级.QSGS溶液具有很好的耐酸、耐碱、耐盐等化学稳定性.

The epoxy group polyether polysiloxane (EPEPS) was prepared by hydrosilylation of α,ω-hydro?gen silicone (α,ω-PHMS) and al yl epoxy groups polyether (APEE) in the presence of a platinum catalyst using anhydrous ethanol as the solvent. A kind of novel quaternary ammonium organic silicon Gemini surfactant (QSGS) was synthesized by the ring-opening reaction of EPEPS with N,N-dimethyl dodecyl tertiary amine (DMA12). The chemical structures of QSGS and EPEPS were characterized by IR. The properties of QSGS, such as critical micel e concentration, surface tension, foaming power, acid, alkali and salt resistance and stabil?ity in hard water were investigated. The experimental results showed that the critical micel e concentration (cmc) of QSGS solution was 1.6 g/L, the surface tension at cmc (γcmc) of QSGS solution was 25.5 mN/m. The foaming power of 0.5% QSGS (mass fraction) solution was 1.63 and foam stability after 5 min was 0.158. The stability of QSGS in hard water was grade 5. The QSGS solution had excel ent chemical stability of acid, alkali and salt resistance.
