The invention relates to an aqueous alkyd acrylic resin paint and a preparation method thereof. According to the invention, high-molecular alkyd resin with main chain containing unsaturated double bond is synthesized through molecular design. Alkyd resin is subjected to free radical graft copolymerization with acrylic monomer. A reaction system is neutralized by using an amine compound, such that water-reducible alkyd acrylic resin is synthesized. Molecular chains of alkyd and acrylic resins are connected through chemical bond, such that the compatibility of the two resins is improved. In a material curing and shaping process, phase separation of the resin is avoided. Deionized water, a pigment, a filling material, an antifoaming agent, a dispersing agent, a siccative, and alkyd acrylic hybrid emulsion are uniformly dispersed, such that the aqueous alkyd acrylic resin paint is obtained. The aqueous alkyd acrylic resin paint comprises the components of: aqueous alkyd acrylic resin 65%-80%, the pigment 3%-4%, the filling material 6-10%, deionized water 10%-20%, the dispersing agent 0.05%-0.5%, the antifoaming agent 0.10%-0.30%, and the siccative 0.9%-3.5%. |
