Polyamide-imide finish for corona-resistant enameled wire

The invention discloses polyamide-imide finish for a corona-resistant enameled wire. The polyamide-imide finish comprises, in terms of the total weight accounting for 100 parts, components as follows: 1-10 parts of a lubricating abrasion-resistant component, 1-10 parts of a solvent and the balance of base paint, wherein the lubricating abrasion-resistant component is a mixture of molybdenum disulfide, sepiolite powder, polytetrafluoroethylene, polyethylene wax and silicone oil in the ratio of (20-30):(20-30):(15-25):(15-25):(5-15) in terms of the total weight accounting for 100 parts; the solvent is a mixture of N-methylpyrrolidone and xylene in the weight ratio of (1-2):1; the base paint is polyamide-imide paint. The polyamide-imide finish can decrease the static friction coefficient of the corona-resistant enameled wire, is good in improvement effect on the corona resistance of the corona-resistant enameled wire and is applicable to driving motors of new-energy vehicles.
