The title aqueous alkyd resin emulsion was prepared by phase inversion process，and the influence of stirring speed，addition rate of water and the emulsification temperature on the preparation of emulsion were investigated. The results showed that thefavorite emulsification condition was as follows：the emulsifier level，200# solvent，and KOH were 5%，3%，and 0.5%，respectively，the stirring speed between 4000 and 6000r/min，the addition rate of water adding 90~120mL/h，and emulsification temperature 50~60 ℃. The particle size of the emulsion D90≤307 nm. The stability of the emulsion and other properties ofthe coatings film met the relevant national standards.
