In this paper, self-healing microcapsules with urea formaldehyde coated Nippon water-based acrylic acid were prepared, and the performance of water-based topcoat paint film added with self-healing microcapsules and the repair effect of microcapsules were investigated. The results show that when the content of microcapsules in water-based topcoat paint film on the surface of wood increased, the color difference and hardness rose gradually, the gloss and adhesion declined gradually, the impact resistance and tensile strength at break rose first and then declined. The 0.67:1 core-wall ratio microcapsules had a better micromorphology, and the water-based topcoat paint film with 0.67:1 microcapsules had a certain repair effect. The microcapsules were added to the water-based topcoat paint film to repair the coating to a certain extent, which provide technical reference for prolonging the service life of water-based topcoat paint film for the furniture surface.
