| 摘 要： | 以1，3-二（3-缩水甘油醚丙基）-1，1，3，3-四甲基二硅氧烷（EDH）和八甲基环四硅氧烷（D4）为原料合成了端环氧硅油（ETSO），以ETSO为原料与葡甲胺胺化得到中间体有机硅嵌段硅油（PTSO），然后用γ-氯丙基三甲氧基硅烷（CPTSO）季铵化改性制备了Bola有机硅季铵盐（BPTSO）。BPTSO的季铵化过程最优合成工艺条件为：反应温度为80℃，物料摩尔比为n（PTSO）∶n（CPTSO）=1∶1.2，反应时间为3 h，PTSO转化率达98.60%。通过FT-IR、1H NMR、TGA、TEM对BPTSO的结构及BPTSO乳液整理后织物的微观形貌进行了表征。测试结果表明：BPTSO乳液的表面张力γ 为29.4 mN/m，临界胶束浓度CMC为0.036 mmol/L，具有囊泡结构和优越的稳定性，经BPTSO乳液整理后的棉织物具有优异的柔软度、白度及亲水性，当BPTSO乳液的用量为60 g/L时，对棉织物的增深率可达到46.5%。

| Abstract: | Epoxysilicone oil (ETSO) was synthesized with (3-glycidoxypropyl)-1,1,3,3- tetramethyldisiloxane (EDH) and octamethylcyclotetrasiloxane (D4) as raw material first. Then intermediate organosilicone block silicone oil (PTSO) was obtained by amination with meglumine. Finally, Bola silicone quaternary ammonium salt (BPTSO) was synthesized by quaternization of PTSO and γ-chloropropyltrimethoxysilane (CPTSO). The process conditions of BPTSO were optimized as follows: the reaction temperature was 80℃, the molar ratio of material was n(PTSO)∶n(CPTSO)=1∶1.2, the reaction time was 3 h, and the conversion rate of PTSO was 98.60%. The structure and morphology of BPTSO were characterized by FT-IR, 1H NMR, TGA, SEM and TEM. The results of performance test show that BPTSO have core-shell structure and superior stability, the fabrics treated with BPTSO emulsion had excellent softness, whiteness and hydrophilicity. The depth enhancement rate of cotton fabric reached 46.5%. |
