The invention relates to the field of IPC C09D133/00, in particular to a water-based single-component high-fullness roller coating white primer and a preparation method and application thereof. The raw materials include, in percentage by weight: 10-45% of aqueous emulsion, 5-70% of pigments and fillers, 0.5-12% of auxiliary, 2-8% of film-forming agent, and solvent supplementary balance. The invention provides a white primer for roller coating, which adopts a water-based one-component formulation system, uses an acrylic emulsion and a water-based polyurethane dispersion to act together, and cooperates with the action of specific additives to increase the oiling amount during the roller coating operation, and the obtained The paint film has excellent leveling and fineness, enhanced mechanical properties of application, significantly improved fullness, and smooth hand feeling, and the present invention is suitable for wide promotion in the field of water-based paints. |
