摘　　要：以烯丙基环氧基聚醚、α,ω-含氢硅油和N,N-二甲基十二烷基胺等为原料,经硅氢加成、季铵化两步反应制得了一种新型阳离子型有机硅双子表面活性剂(CSGS).CSGS的结构采用红外光谱(IR)进行了确认,并对CSGS的临界表面张力(γcmc)、临界胶束浓度(cmc)、耐酸碱盐稳定性以及其对整理织物的应用性能等进行了测试.结果表明:CSGS水溶液的γcmc为25.5mN·m-1,cmc为1.6g·L-1,CSGS溶液具有很好的耐酸、耐碱、耐盐等化学稳定性.和空白布样相比,经CSGS水乳液整理后的织物的弯曲刚度由453mN降为219mN,织物的柔软性显著提高,但白度值由78.62变为73.88,白度有所下降,而吸水性几乎不变.A kind of novel cation silicone gemini surfactant（CSGS）was synthesized through hydrosilylation and quaternization two-step reaction using the allyl epoxy groups polyether（APEE）,alpha omega hydrogen silicone（α,ω-PHMS）and N,N-dimethyl dodecyl amine（DMA12）as the raw material.The chemical structure of CSGS was confirmed by infrared spectroscopy（IR）.The properties of CSGS,such as critical surface tension（γcmc）,critical micelle concentration（cmc）,stability in acid,alkali and salt solution,as well as application performance of the treated fabric were investigated by experiment.Experimental results were showed as follows.Theγcmcof CSGS solution is 25.5mN/m,cmc of CSGS solution is 1.6g/L.The CSGS solution has good chemical stability in acid,alkali and salt solution.Compared with the blank sample,the softness of the cotton fiber treated by CSGS water emulsion has improved significantly with bending rigidity reduced from 453 mN to 219 mN.And the whiteness has decreased with whiteness value changed from 78.62 to 73.88.But the wettability has almost not changed.
