This invention provides an exposed single-component waterproof coating with self-healing function, its preparation method, and its application. The exposed single-component waterproof coating, based on a total weight percentage of 100 wt%, comprises: 25-50 wt% fluorocarbon emulsion, 5-20 wt% microcapsule self-healing agent, 0.1-1 wt% water-resistant agent, 0.1-3 wt% film-forming aid, 0.1-1 wt% stabilizer, 0.1-1 wt% bactericide and preservative, with the balance being water. The fluorocarbon emulsion is a core-shell polymer emulsion. The outer shell is formed by emulsion polymerization of fluorinated acrylate monomers, furan-structured monomers, and maleimide-structured monomers, while the core is formed by emulsion polymerization of soft acrylate monomers and hard acrylate monomers. The emulsion polymerization is carried out in an aqueous solution containing emulsifiers and initiators. The microcapsule self-healing agent has a core-shell structure, including a urea-formaldehyde resin shell and a fluorooil core material encapsulated within the urea-formaldehyde resin shell.

This application relates to the field of building decoration materials, and in particular to a crack-resistant metallic paint and a high-strength steel plate crack-resistant component, as well as their construction method. A crack-resistant metallic paint comprises the following raw materials in parts by weight: 300-500 parts fluorocarbon emulsion, 80-120 parts elastic emulsion, 10-40 parts active toughening agent, 90-110 parts metallic effect pigment, 30-40 parts film-forming aid, 1.5-2.5 parts dispersant, 15-20 parts thickener, and 280-350 parts water. By compounding the fluorocarbon emulsion and elastic emulsion and adding the active toughening agent, the paint film achieves an elongation at break ≥82%, a flexibility of 1mm without cracking on a shaft, and resistance to artificial aging ≥3000h without cracking, thus achieving a synergistic unity of high elasticity and high weather resistance.
