The invention relates to a preparation method of a waterborne acrylic modified saturated polyester resin. Polyacid, polybasic alcohol and tertiary carbonate glycidyl ester are used for the synthesis of unsaturated polyester resin; then under the effect of an initiator, acrylic monomers are used for the modification of saturated polyester resin; a neutralizing agent is added, and water is used for adjusting the solid content, so as to obtain the waterborne acrylic modified saturated polyester resin. The waterborne acrylic modified saturated polyester resin prepared by the invention has the advantages of excellent stability, high solid, low viscosity and low VOC content, and is mainly used in amino baking finish for waterborne coating. |
