Abstract

The invention relates to the field of a textile finishing agent, and particularly relates to a method for preparing a super-smooth hydrophilic quaternary ammonium salt-modified organic silicon copolymer. The method comprises the following steps: synthesizing a cationic modified polyether amine intermediate by using aliphatic polyether diamine and an alkylating agent under the action of an acid catalyst; carrying out addition polymerization of amino and an epoxy group on the cationic modified polyether amine intermediate and terminated epoxy polyether silicone oil in the presence of an organic solvent, then adding a glacial acetic acid, and synthesizing ternary block silicon oil. The super-smooth hydrophilic quaternary ammonium salt modified organic silicon copolymer prepared by the method provides excellent hydrophilic performance to cotton fabric, and has an outstanding smooth effect, and the smoothness can achieve the level of common amino silicon oil, and is superior to that of most of ternary block silicon oil. The super-smooth hydrophilic quaternary ammonium salt modified organic silicon copolymer has certain antibacterial and antistatic functions by improvement of the cationization degree, meanwhile, the problem that amino is easy to yellow in a high-temperature condition can be effectively solved, and the processed fabric is small in yellowing, and applicable to finishing of white or light fabric.

Description

technical field [0001] The invention relates to a preparation method of a textile finishing agent, in particular to a preparation method of a super-smooth hydrophilic quaternary ammonium salt-modified organosilicon copolymer. Background technique [0002] Since Momentive launched the first ternary copolymerized block silicone oil SRS to enter the Chinese market, in recent years, the domestic market of ternary copolymerized silicone oil has developed very fast, especially in 2011-2012, ternary block silicone oil has been used in silicone softeners The market share has exceeded 20%. It can be said that among the hand finishing agents for textiles on the market, ternary block silicone oil or its further modified products are gradually replacing traditional amino silicone oil products. As we all know, compared with amino silicone oil, it can self-emulsify or disperse in water without emulsifier, has the characteristics of shear resistance, acid resistance, alkali resistance, hig...
