The invention discloses a formula of an alkyd for monoacid-modified paint, and a formula design and preparation method thereof in keeping with the invention, a whole set of formula design computation modes is established by using the mole computation standard. The synthetic resin for illegal vegetable oil or acidified edible fat alkyd paint is ready from the subsequent components in parts by mass: 30-50 parts of illegal oil or acidified edible fat, 10-18 parts of rosin or the other monoacid, 2-10 parts of pentaerythritol, 2-10 parts of glycerol, 10-30 parts of waste or defective terephthalic acid, 2-6 parts of reflux dimethyl benzene and 20-40 parts of 200 solvent oil. The preparation method comprises the subsequent steps: pre-esterifying, alcoholysis, and re-esterifying, wherein the high-acid value animal and oil, illegal vegetable oil, or acidified oil don't need alkali bleaching. The prepared product has the benefits of low cost and favorable properties for preparing alkyd-ready mixed paint.
