The invention relates to a microcapsule, a self-healing electrophoretic coating containing the microcapsule and a preparation method of the microcapsule. The microcapsule mainly takes urea formaldehyde resin or melamine resin as a capsule wall and silane coupling agent modified epoxy resin as a capsule core. The microcapsule has the beneficial effects that the microcapsule is prepared by in situ polymerization, takes the urea formaldehyde resin or melamine resin as the capsule wall and the silane coupling agent modified epoxy resin as the capsule core, and has the advantages of being good in microcapsule toughness, not easy to damage, small in particle size and good in stability. After an electrophoretic coating is introduced into the microcapsule, micro cracks or damage of a paint film can be self-healed, so as to improve the overall corrosion resistance of the paint film.
