Abstract
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.

The color difference of the water-based topcoat paint film increased with the content of microcapsules increased, from 0.6 to around 5.0
Summary
Microencapsulation is a kind of packaging technology that can store and protect the core material for a long time, and release the core material when needed. The effect of microcapsules on the self-healing properties of epoxy resin coating was studied. The results show that the microcapsules added to the water-based primer film had better liquid resistance, good stability and aging resistance. The water-based acrylic acidwith coated urea crack self-healing effect [13,14,15,16,17]. The water-based acrylic acid coated ureawith formaldeformaldehyde is aofkind of self-healing microcapsule. The wood surface coated by hyde is a kind self-healing microcapsule. Was was coated by wawater-based topcoat paint with microcapsules that can repair the cracks [18,19,20]. Ter-based topcoat paint with microcapsules that can repair the cracks [18,19,20].
