A method for preparing a two-component waterborne polyurethane modified alkyd wood varnish. The varnish consists of a component A and a component B. The ratio of the component A to the component B is 1:1.2 to 1:1.4 according to OH:NCO. The component A consists of water-soluble alkyd resin, a base material wetting agent, a leveling agent, extinction powder, a dispersant, a defoamer, a bactericide, a film coalescing aid, and deionized water. The component B is a waterborne polyurethane curing agent. The two-component waterborne polyurethane modified alkyd wood varnish has excellent water resistance, chemical resistance, heat resistance and aging resistance. |
