The invention discloses wire enamel with a high thermal level and high abrasion resistance. The wire enamel is characterized by being prepared from raw materials in parts by weight (kilogram) as follows: 11-13 parts of phenolic resin, 11-15 parts of nylon 12, 3-6 parts of precipitated barium sulfate, 12-16 parts of polyurethane resin, 11-17 parts of E-12 epoxy resin, 1-2 parts of butyltin oxide, 2-3 parts of polyvinylpyrrolidone, 5-7 parts of phenyl glycidyl ether, 8-10 parts of neopentyl glycol, 2-4 parts of diphenylmethane diisocyanate, 1-3 parts of a silane coupling agent KH550, 7-9 parts of trimethylolpropane triacrylate, 1-2 parts of potassium acetate, 7-9 parts of an assistant, 95-115 parts of m, p-cresol and 100-120 parts of xylene. According to the wire enamel with the high thermal level and high abrasion resistance and a preparation method of the wire enamel, the preparation method is simple, the cost is low, a wire enamel film prepared with the preparation method has good adhesiveness and excellent scratch resistance, the temperature classification of the prepared wire enamel can be up to 200 DEG C, the oil resistance is good, the process redundancy is high, and steady technological production can be realized conveniently.
