Abstract

The invention relates to the field of textile finishing agents, in particular to a method for preparing a super-slippery hydrophilic quaternary ammonium salt-modified organosilicon copolymer, which comprises the following steps: Synthesize cationic modified polyether amine intermediate under the following conditions; add glacial acetic acid to the cationic modified polyether amine intermediate and epoxy-terminated polyether silicone oil for addition polymerization of amino and epoxy groups in the presence of an organic solvent , Synthetic ternary block silicone oil. The super-slippery hydrophilic quaternary ammonium salt modified silicone copolymer prepared by the present invention endows cotton fabrics with excellent hydrophilic properties and outstanding silky effect, and its smoothness can reach the level of ordinary amino silicone oil, which is better than most ternary silicone oils. Block silicone oil; the improvement of the degree of cationization endows the super-smooth hydrophilic quaternary ammonium salt modified silicone copolymer with certain antibacterial and antistatic functions, and at the same time can effectively solve the problem of easy yellowing of amino under high temperature conditions. Smaller, suitable for finishing white or light colored fabrics.

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...
