Abstract

The invention provides an alkynol modified fluorine-containing polyester compound, a preparation method thereof, an anti-oil stain auxiliary agent and application of the anti-oil stain auxiliary agent. The structural formula of the alkynol modified fluorine-containing polyester compound is shown in the specifications. The preparation method of the alkynol modified fluorine-containing polyester compound comprises the following steps of: mixing raw materials including binary acid, fluorine-containing unit alcohol and a first solvent, and carrying out a first reaction to obtain a fluorine-containing polyester prepolymer; and mixing materials including the fluorine-containing prepolymer and alkynol, and carrying out a second reaction to obtain the alkynol modified fluorine-containing polyestercompound. The anti-oil stain auxiliary agent comprises the alkynol modified fluorine-containing polyester compound. The application of the anti-oil stain auxiliary agent is used for anti-oil stain treatment of textiles. The alkynol modified fluorine-containing polyester compound provided by the invention has excellent oil stain resistance.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to an acetylenic alcohol-modified fluorine-containing polyester compound, a preparation method thereof, an anti-oil pollution auxiliaries and applications thereof. Background technique [0002] From the perspective of the development trend of textiles at home and abroad and the needs of people's lives, people pay more and more attention to multifunctional products with high technical content. A large number of textiles such as clothing fabrics, non-woven fabrics, curtains and other home decorations, industrial textiles, etc. urgently require multi-functional finishing such as waterproof, oil-proof, and stain-proof without changing the fabric's air permeability and moisture permeability. performance. [0003] The existing additives still need to be improved in terms of anti-oil stain effect and oil stain resistance stability. [0004] In view of this, this application is proposed...
