Abstract

The invention relates to a fluorine-containing polyether acrylate polymer and a preparation method thereof. The structural formula of the polymer is shown in the specifications. The preparation method comprises the following steps of: (1) dissolving an emulsifier into a solvent, and stirring at the temperature of 20-200 DEG C for 2-24 hours to obtain an emulsion; (2) dropwise adding a functional monomer and fluorine-containing polyether acrylate into the emulsion respectively, stirring at the temperature of 20-200 DEG C for 2-24 hours, and performing ultrasonic treatment for 2-24 hours to obtain a pre-emulsion; and (3) under the protection of N2, heating to 20-200 DEG C, dropwise adding an initiator into the pre-emulsion, and reflowing for 2-24 hours. The fluorine-containing polyether acrylate polymer has the advantages of easiness for biodegrading, low environmental pollution and simple preparation method; and perfluoropolyether is adopted instead of long chain perfluoralkane, so that the defects of non-biodegradability of long chain perfluoralkane and harm of perfluoroctane sulphonated substance serving as a raw material of long chain perfluoralkane to human beings are overcome.

Description

technical field [0001] The invention belongs to the field of water and oil repellent finishing agent and its preparation, in particular to a fluorine-containing polyether acrylate polymer and its preparation method. Background technique [0002] At present, with the development of domestic and foreign textiles and the improvement of people's living standards, people's demand for high-quality, multi-functional coatings and textiles is increasing.
