The invention relates to a room-temperature self-crosslinkable polyacrylic wood varnish. The wood varnish is prepared from the following components by weight: 75-85 parts of a polyacrylic emulsion, 0.1-0.3 part of a water-based multifunctional regulator, 0.3-0.5 part of a defoaming agent, 0.1-0.3 part of a wetting agent, 0.2-0.4 part of a sterilizing mildew inhibitor, 1-2.5 parts of an antifreezing agent, 3-6 parts of a thickening agent, and 10-15 parts of deionized water. Compared with conventional acrylic wood varnishes, the room-temperature self-crosslinkable polyacrylic wood varnish provided by the invention has no need of a film-forming assistant, reduces the VOC emission, and also has the advantages of high solid content, high hardness, excellent water resistance, strong adhesion and high impact strength.
