| titleOfInvention | High-solid self-repairing type waterborne polyurethane acrylate and preparation method thereof |
| abstract | The invention relates to the technical field of coating materials, and provides a preparation method of a high-solid-content aqueous polyurethane acrylate dispersion, which comprises the following steps: reacting diisocyanate with polyester polyol or polyether polyol to obtain a polyurethane prepolymer; mixing and reacting the polyurethane prepolymer with a viscosity-reducing solvent, a hydrophilic chain extender and a dihydric alcohol chain extender containing a disulfide bond to obtain a first mixed solution; mixing the first mixed solution and hydroxyl-containing acrylate monomers for reaction to obtain a double-bond-terminated polyurethane prepolymer; adding water into the double-bond-terminated polyurethane prepolymer for emulsification, removing the solvent to obtain a second mixed solution, mixing and emulsifying the second mixed solution and the acrylate monomer, and mixing and reacting the second mixed solution and the initiator solution. A high-solid aqueous polyurethane acrylate dispersion is prepared by the method, and when the high-solid aqueous polyurethane acrylate dispersion is used as a coating film, a coating material with self-repairing performance is prepared by the method. The coating material has good self-repairing performance under irradiation of visible light and ultraviolet light and at a proper temperature. |
