Abstract

The invention discloses a cationic waterborne organic fluorine acrylate polymer as well as a preparation method and application of the cationic waterborne organic fluorine acrylate polymer. The cationic waterborne organic fluorine acrylate polymer is prepared by using a semicontinuous dripping method and taking perfluoroalkyl acrylates and acrylate as main monomers, a reactive unsaturated monomer as a modified monomer, a cationic Gemini surfactant and a nonionic emulsifying agent as an emulsion system and water-soluble azobis(isobutylamidine hydrochloride) as an initiator. The polymer system disclosed by the invention is high in stability, and the emulsion storage stability is not shorter than 12 months. A textile treated by using the emulsion prepared by the invention has better water and oil repellent effects.

Description

technical field [0001] The invention belongs to the field of preparation of water and oil repellent finishing agents for fabrics, and relates to a cationic water-based organic fluorine acrylate polymer used as a water and oil repellent finishing agent for fabrics, a preparation method and application thereof. Background technique [0002] Fluorine is the most electronegative element in the periodic table of elements. When the hydrogen of the carbon-hydrogen bond is replaced by fluorine, since the covalent radius of the fluorine atom is only half of the length of the C-C bond, the fluorine atom can make the carbon-hydrogen bond very It is well shielded and maintains a high degree of stability; at the same time, due to the small polarizability of the C-F bond and the short bond distance, the intermolecular cohesion of the compound containing a large number of C-F bonds is small, so that the surface energy is greatly reduced. Generally, when surfactants are dissolved in water, ...
