Abstract

The invention relates to the technical field of carbon brushes, and specifically relates to a high-wear-resistance motor carbon brush doped with chromium carbide, and a preparation method for the high-wear-resistance motor carbon brush. A carbon brush product employs medium-temperature coal-tar pitch and polyamide resin as an adhesive, wherein the composite adhesive is good in adhesive strength, is light in weight, is high in strength, is resistant to corrosion, and is durable and efficient in binding. The doped chromium carbide is good in stability, is high in strength, is good in conductivity, is resistant to wear, and effectively prolongs the service life of carbon brush materials. The addition of nano carbon sol improves the conductivity of the carbon brush, and improves the wear resistance. The carbon brush is excellent in conductivity, is stable in operation, is good in wear resistance, and is longer in service life.
