Abstract

The invention belongs to the field of textile post-finishing auxiliaries and particularly relates to double amino type block polyether amino silicone oil and a preparation method thereof. The double amino type block polyether amino silicone oil is characterized in that the structural formula of a compound is shown as follows (structural formula 1), wherein EO is -CH2CH2O-, PO is -CH(CH3)CH2O-, n is 50-500, a is 10-40, b is 0-6, m is 2-40, and R is -CH2CH2- and -CH(CH3)CH2-, -CH2CH2CH2-or -CH2CH2CH2Ch2-. The double amino type block polyether amino silicone oil prepared by the invention can be compared with ordinary amino silicone oil in mouth feeling, has less influence on the whiteness of a fabric, simultaneously has excellent acid and alkali resistance, shear resistance and salt resistance, can completely replace the ordinary amino silicone oil and has an optimal application prospect.

Description

technical field [0001] The invention belongs to the field of textile post-finishing auxiliaries, in particular to a diamino type 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 amino s...
