The invention relates to a polyacrylic woodware emulsion with a core-shell bi-crosslinking structure and a preparation method thereof. The polyacrylic woodware emulsion is prepared from the following components: methyl methacrylate, butyl methacrylate, methacrylic acid, a crosslinking monomer, butyl acrylate, methacrylic acid-2-hydroxy ethyl, diacetone acrylamide, adipic dihydrazide, an initiator, an emulsifier, and deionized water. Through molecular design of the polyacrylic emulsion with hard core and soft shell, the hard core provides the hardness and mechanical strength of a coating film and improves the stain resistance of a paint film, and the soft shell can improve the film-forming property of coating film, has no need for film-forming assistant, reduces VOC emission, and improves the low temperature resistance of the coating film. By means of the core-shell bi-crosslinking system, the hardness and water resistance of the paint film are improved.
