Problems solved by technology

Under the action of tertiary amine catalyst, Knott et al. used A,X-diamino-terminated silicone oil and polyoxyethylene polyoxypropylene glycol to react in the presence of toluene solvent to prepare block-type amino polyether silicone oil, but the reaction conditions of this method are harsh. And toluene solvent is highly toxic, and its popularization is limited

Abstract

The invention discloses block polyether amino silicone oil, particularly relates to a method for preparing modified block polyether amino silicone oil and aims at overcoming defects of existing technologies. The method for preparing the modified block polyether amino silicone oil is simple in preparation process and operation, short in reaction time, mild in reaction conditions, easy to implement and capable of improving hydrophily and inhibiting yellowing, and raw materials are easy to obtain; and the block polyether amino silicone oil is synthesized and modified by an epoxy compound to obtain the modified block polyether amino silicone oil.

Description

technical field [0001] The invention relates to a block polyether amino silicone oil, in particular to a preparation method of a modified block polyether amino silicone oil. Background technique [0002] Ordinary amino silicone oil is a kind of softener widely used in the textile industry. It can improve the fabric feel, make it soft, smooth, anti-wrinkle and other properties, and it is not harmful to the human body, so it is very popular. However, amino silicone oil makes the fabric fiber show a certain degree of combability, which reduces the comfort and hygroscopicity of the fabric. At the same time, it is easy to yellow, sensitive to high pH value, high temperature, etc., and easily produces oil spots and other phenomena. [0003] In view of the above defects, people use various methods to modify it, among which polyether modification is a better way to improve the hydrophilicity of amino silicone oil-finished fabrics. An Qiufeng and others prepared side-chain polyether...
