The invention discloses an anti-corrosion bonding copper wire and a preparation method thereof and relates to the technical field of bonding copper wires. The anti-corrosion bonding copper wire comprises a copper wire body, grooves are formed in the surface of the copper wire body, the inner walls of the grooves are fixedly connected with graphite blocks, and alloy blocks are fixedly connected with the sides, away from the inner walls of the grooves, of the graphite blocks. Alloy rings are embedded in the surface of the copper wire body, and the vertical planes where the alloy rings are located are parallel to the vertical planes where the alloy blocks are located. Alloy sheets are embedded in the surface of the copper wire body, the alloy sheets are arranged on the surfaces of the graphite blocks in an overlap joint mode, the number of the alloy sheets is four, the number of the grooves is four sets, and each set of grooves is located between the two corresponding adjacent alloy sheets. According to the anti-corrosion bonding copper wire and the preparation method thereof, due to the arrangement of the alloy sheets and the alloy rings, the problems that an existing bonding copperwire is abraded after being used for a long term, consequently a protecting layer falls off, anti-oxidation and anti-acidification performance becomes poor, and the service life of the bonding copperwire is shortened are solved.
