The invention belongs to the technical field of powder coating synthesis, and in particular relates to a high temperature-resistant and water-boiling-resistant leveling agent, and further discloses a preparation method thereof and an application for preparing powder coatings. The leveling agent for powder coatings of the present invention greatly improves the high temperature resistance and anti-yellowing effect of the leveling agent by introducing 2-(perfluorooctyl)ethyl methacrylate as a fluoromonomer raw material; The introduction of 10-hydroxy-2-decenoic acid and methacrylic alcohol makes the final leveling agent product contain both hydroxyl and carboxyl groups, which greatly improves the compatibility with polyester resins and epoxy resins, making The leveling agent can participate in the reaction when the powder coating is cured, so that it is not easy to be lost when boiled at high temperature, which can better improve the surface defects of the powder coating film and improve the leveling effect, so as to obtain high temperature and boiling resistance powder. Coating film. |
