The invention provides a paint immersing process for insulating paper, comprising the following steps: step 1, adding insulating paint in a container to blend paint; step 2, drying a base band of the insulating paper; step 3, entirely immersing the processed base band of the insulating paper into the insulating paint; or spraying the insulating paint onto the base band to cover the surface thereof; and step 4, taking out the base band to dry at controlled temperature till solidifying the insulating paint and the base band of the insulating paper. The paint immersing process is simple and practical to operate. The base band can directly cover a conductor as an insulator. As the insulating paint has a certain adhesive property, the structure of conductor with the insulating paper becomes more stable. After the conductor is wound into a coil, free of another immersing process, simplifying production.
