Abstract

The invention relates to quaternary ammonium modified block polyether / amino silicone oil and a preparation method thereof. The preparation method comprises the following steps: bis(glycidoxy-terminal), DMC and an organic solvent, adding an alkaline catalyst, heating to 80-110 DEG C, and balancing for 6-8 h; heating to about 140 DEG C to decompose the catalyst for 1-2 h, and carrying out underpressure distillation to obtain colorless or flavescent epoxy-terminated silicone oil; uniformly mixing the epoxy-terminated silicone oil, polyetheramine and a solvent, reacting at 60-80 DEG C for 15-20 h to prepare a block polyether / amino silicone oil prepolymer; and respectively adding a tertiary amine compound and equimolar quantity of organic acid into the product obtained in the step b, continuously reacting at 70-80 DEG C for 4-8h so as to obtain the final product. The amino silicon oil prepared by the method has excellent hand feeling, has little influence on whiteness and hydrophilicity of fabrics, can completely replace common amino silicon oil, and has an excellent application prospect.

Description

technical field [0001] The invention belongs to the field of textile post-finishing auxiliaries, in particular to a quaternized modified block polyether amino silicone oil and a preparation method thereof. Background technique [0002] Ordinary amino silicone oil has been gradually replaced by various types of block polyether modified amino silicone oil due to the disadvantages of poor emulsion stability, easy yellowing of the treated fabric, and poor moisture absorption and perspiration. Due to the introduction of the hydrophilic polyether segment, the stability of the emulsion is good. Moreover, the structure in which polyether segments are embedded in the main chain has little effect on the film-forming properties of polysiloxane on fabric fibers, and it is easy to exert its soft, smooth and fluffy properties. This is the advantage of block polyether amino silicone oil over ordinary amino silicone oil. [0003] However, the amino functional groups in the block polyether...
