Quaternary ammonium type hydrophilic amino-modified silicone oil emulsion and preparation method thereof

The invention discloses a preparation method of a quaternary ammonium type hydrophilic amino-modified silicone oil emulsion. The preparation method includes the following preparation steps that firstly, amino-modified silicone oil is prepared from alpha,omega-hydroxy polydimethyl siloxane (linear organosilicon), an amino coupling agent, a sealing agent and a basic catalyst, then the amino-modified silicone oil and dimethylaminoethyl methacrylate react, acrylate-modified amino-modified silicone oil is obtained, and finally quaternization is carried out through methyl chloroacetate. The quaternary ammonium type hydrophilic amino-modified silicone oil emulsion is simple in preparation process, has self-emulsifying performance, and is used for after-finishing of fabrics, and the fabrics are made to have excellent soft and slip hand feeling, and are low in yellowing, small in color alteration and good in hydrophilicity. 本发明公开了种季铵型亲水氨基硅油乳液的制备方法。其制备步骤如下：首先，用α,ω-羟基聚二甲基硅氧烷（有机硅线性体）、氨基偶联剂、封头剂、碱性催化剂制备氨基硅油，然后将所述氨基硅油与甲基丙烯酸
