Self-adhesive enameled flat copper wire and preparation method thereof

The invention relates to a self-bonding enameled flat copper wire which comprises a copper conductor, a basic insulating layer and a self-bonding insulating layer, wherein the basic insulating layer and the self-bonding insulating layer sequentially coat the copper conductor from inside to outside; when the self-bonding insulating layers are used for winding, the adjacent bonding insulating layers can be automatically bonded with each other after being heated; after a product is heated in an electrified heating or hot air heating mode, the self-bonding insulating paint film on the outermost layer of the flat copper wire completes a self-bonding function after being heated, so that the shape of a flat wire winding is automatically fixed and formed, and after natural cooling, the flat wire winding is formed in a self-bonding mode. And the complete mechanical performance, moisture resistance and chemical stability resistance of the motor flat wire winding are maintained. In the self-bonding process, extra plant
