Abstract

The invention relates to an acrylamide copolymer containing halothane and phosphoric acid ester as well as a preparation method and the application thereof. The preparation method comprises the steps of: (1) dissolving monomer, crosslinking monomer and non-fluoro long-chain monomer of the acrylamide copolymer containing halothane and phosphoric acid ester and emulsifier in deionized water and solvent for ultrasonically pre-emulsifying for 1-5h to obtain milk-white pre-emulsion; (2) under the protection of N2, heating 1 / 3 of the pre-emulsion to 60-90 DEG C, slowly dropping an initiator aqueous solution for initiating reaction, stopping dropping after the emulsion has blue fluorescence, combining the residual initiator aqueous solution with the pre-emulsion, slowing dropping the combined residual initiator aqueous solution and pre-emulsion into reaction liquid, stopping reaction after continuously reacting for 1-5h at 60-90 DEG C, and cooling down to the room temperature to obtain the required emulsion PFPA (Per Fluoro Propionic Anhydride). In the invention, cotton fabric processed by the copolymer emulsion has excellent performances of resisting water, oil and flame, the processing process is simple, and greater development potency is provided.

Description

technical field

[0001] The invention belongs to the field of preparation and application of multifunctional finishing aids for fabrics, and in particular relates to a preparation method and application of an acrylamide copolymer containing fluoroalkyl phosphonate groups. Background technique

[0002] At present, a lot of attempts have been made in the water and oil repellent finishing of fabrics. Fluorine-containing acrylate polymers contain perfluoroalkyl groups on the side chains, and the perfluoroalkyl side chains are oriented outwards, so their surface free energy is low, and they have good water and oil repellency, while acrylates have high The molecule itself has the characteristics of good film-forming property and relatively loose network structure, so the fabric treated with fluorine-containing acrylate fabric finishing agent can obtain excellent waterproof, oil-proof, anti-fouling, breathable, moisture-permeable characteristics and good chemical stability , therma...
