Oleophylic self-repairing anti-fouling coating, preparation method thereof and self-repairing film

The invention relates to the technical field of self-repairing coatings, and particularly discloses an oleophylic self-repairing anti-fouling coating, a preparation method thereof and a self-repairing film. The oleophylic self-repairing anti-fouling coating is prepared from the following components in parts by weight: 20 to 26 parts of curing agent, 40 to 50 parts of organic solvent, 10 to 20 parts of oleophylic modified acrylic resin and 8 to 12 parts of modified polyurethane, the modified polyurethane is obtained by taking polyol and isocyanate as raw materials and 2, 2-dimethylolbutyric acid, 1, 4-butanediol, 1, 3-bis (hydroxymethyl) urea and N-(2-aminoethyl)-2-aminoethanesulfonic acid sodium salt as chain extenders through a four-step chain extension reaction. The oleophylic self-repairing anti-fouling coating disclosed by the invention can be used for preparing a self-repairing film, and has the advantages of high repairing efficiency, good lipophilicity and relatively strong anti-fouling performance. 本申
