Quaternary ammonium salt modified organic silicon as well as preparation method and application thereof

The invention discloses quaternary ammonium salt modified organic silicon as well as a preparation method and application thereof. The preparation method of the quaternary ammonium salt modified organic silicon comprises the following steps: mixing double-end hydrogen-containing silicone oil and allyl-end epoxy polyether, and reacting to obtain double-end epoxy silicone oil; reacting the double-end epoxy silicone oil with quaternary ammonium salt to obtain quaternary ammonium salt modified organic silicon; wherein the quaternary ammonium salt is obtained by reacting alkylol amine with acid. After the quaternary ammonium salt modified organic silicon is used for fabric treatment, the softness and hydrophilic property of the fabric can be well balanced, so that the fabric has excellent hydrophilic property and softness at the same time. 本发明公开了一种季铵盐改性有机硅及其制备方法和应用，所述季铵盐改性有机硅的制备方法为：将双端含氢硅油和烯丙基端环氧基聚醚混合，反应得到双端环氧硅油；使双端环氧硅油和季铵盐进行反应，得到季铵盐改性有机硅；所述季铵盐由醇胺与酸反应得到。本发明的季铵盐改性有机硅在用于织物处理后，可对织物的柔软性和亲水性进行很好的平衡，使织物同时具有优异的亲水性和柔软性。
