Abstract

The invention discloses an environment-friendly type self-crosslinking water and oil repellent fluorinated acrylate textile finishing agent and a preparation method thereof. The preparation method comprises the following steps: mainly introducing a reaction type cation fluorinated emulsifier and a polymerizable cross-linking agent, applying the emulsifier and the cross-linking agent to seeded emulsion polymerization of short fluorocarbon chain perfluoroalkyl acrylate, in situ forming an macromolecular cation organic fluorine copolymer emulsifier during the seeded polymerization process, and in the follow-up emulsion polymerization, enabling the fluorine-containing group to be stably arranged in an emulsion particle shell layer under the action of the polymerizable cross-linking agent; with the results of comprehensive functions of the emulsifier and the polymerizable cross-linking agent, the resin can be used as the textile finishing agent to show up good water repellency, oil repellency and processing continuity.

Description

technical field [0001] The invention relates to the field of fabric finishing auxiliaries, in particular to an environment-friendly self-crosslinking water- and oil-repellent fabric finishing agent and a preparation method thereof. Background technique [0002] The electronegativity of the fluorine atom is large, the radius is small, the bond energy of the carbon-fluorine bond is large, the bond distance is short, and the polarization is small, which makes the fluoropolymer have high heat resistance stability, high chemical stability, high surface activity and Hydrophobic and oil repellent. Fluoroacrylates are easy to copolymerize with acrylate monomers to prepare copolymer emulsions, so they become the most important application of fluoropolymers. [0003] Fluorine-containing acrylates are widely used in many fields such as textile finishing, construction and antifouling coatings, paper processing, electronic appliances, and optical components. However, at present, long f...
