Description

technical field

[0001] The patent of the present invention relates to a water and oil repellent finishing agent and its preparation method and application, in particular to a preparation method and application of a fluorine-containing carbon chain acrylate and its copolymer. Background technique

[0002] At present, with the development of textiles at home and abroad and the improvement of people's living standards, people pay more and more attention to multifunctional textiles with high technical content. Finishing agents that can not only endow fabrics with excellent water-repellent, oil-repellent, and anti-fouling functions, but also are environmentally friendly and harmless to the human body, have increasingly attracted widespread attention.

[0003] Perfluoroacrylate polymers are obtained by introducing perfluoro groups into acrylic polymers and changing the side chain structure of the original polymers. Due to the high electronegativity of fluorine, the C-F bond is ve...
