The invention relates to a quick-drying water-based modified polyester wood coating. The coating comprises the following components in parts by weight, 22 to 28 parts of allyl ether modified polyesterresin, 8-18 parts of epoxy resin, 5-10 parts of a pigment and a filler, 0.2-0.5 part of a water-based dispersing agent, 0.2-1.2 parts of a drier, 0.5-2 parts of an anti-settling agent, 0.2-0.8 part of an antifoaming agent, 0.1-0.6 part of a foam inhibitor, 0.3-0.6 part of a leveling agent, 0.1-0.5 part of an adhesion promoter, 8-15 parts of a cosolvent and 60-110 parts of water. The quick-dryingwater-based modified polyester wood coating prepared by the invention is low in curing temperature and high in drying speed, the construction efficiency is improved, resources are saved, and the costis reduced. Acrylic acid and acrylate functional monomers are introduced into the polyester resin, functions of polyester resin are enriched, acrylic acid and acrylate monomers are swelled and polymerized in a polyester resin n
