Abstract
The invention relates to a preparation method of an negative ion hydrophilic organic silicon emulsion. The emulsion is mainly used for enhancing the flexibility and shrinkage-proof function of a fabric and also has a hydrophilicity function. The method comprises the following steps of: compounding a negative ion emulsifier, polyethylene glycol PEG400 and nonionic emulsifier fatty alcohol polyoxyethylene ether; and performing emulsion polymerization on an epoxy polyether-modified aminosilane coupling agent with a structure shown in the specifications and an organic silicon monomer by taking sulfoacid as a catalyst to obtain the hydrophilic modification emulsion. The organic silicon emulsion prepared by using the method has the solid content between 20 percent and 24 percent, and is a blue-light semitransparent emulsion. The emulsion has an excellent flexibility and shrinkproofing function on a pure cotton fabric, and has a hydrophilicity function.
Description
Technical field
The present invention relates to a kind of organic silicon emulsion, especially relate to a kind of anionic hydrophilic organic silicon preparation of microemulsion method.Be mainly used in the softness, the shrinkproof and possess hydrophilic property effect that improve pure cotton fabric.
Background technology
Organic silicon emulsion plays an important role to feel, the shrinkproof performance of improving fabric in textile industry.At present, the modified organic silicon emulsion as softening agent is made by two-step approach mostly: synthesize amino-modified silicone oil by mass polymerization earlier, carry out microemulsified with suitable emulsifying agent again.After the emulsion of preparation was handled fabric in this way, feel existed not enough, in use made light fabric xanthochromia occur, the appearance of many-sided unstable situation such as floating oil easily simultaneously.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of processing fabric to have softness, shrinkproof performance, simultaneously the preparation method of the anionic hydrophilic organic silicon emulsion of possess hydrophilic property energy.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of preparation method of anionic hydrophilic organic silicon emulsion, this method adopts anionic emulsifier, polyoxyethylene glycol PEG400 and nonionic emulsifying agent fatty alcohol-polyoxyethylene ether composite, sulfonic acid is catalyzer, will be through the amino silicane coupling agent of epoxidized polyether modification, structure is as follows:
Carry out emulsion copolymerization with organosilane monomer, made hydrophilically modified emulsion, its preparation method comprises the steps:
