Abstract

The invention belongs to the carbon brush technical field and relates to a tetrapod-like zinc oxide whisker doped carbon brush for a noise reduction wear-resisting motor and a preparation method of the carbon brush. According to the carbon brush, middle-temperate coal tar pitch, epoxy resin and polyvinyl butyral are mixed together so as to be adopted as an adhesive; and the composite adhesive has strong adhesion for raw materials, high tension and little possibility of cracking, and doped tetrapod-like zinc oxide whiskers has wear resistance, vibration reduction, noise reduction and toughening effects, and therefore, the use performance of the carbon brush can be effectively improved; nano-carbon sol is adopted, and therefore, the electric conductivity of the carbon brush can be improved, and the wear resistance of the carbon brush can be increased. The carbon brush prepared by adopting the method of the invention has the advantages of excellent abrasion resistance in operation, stable operation, low noise, excellent electric conduction performance and no damage to a rotor and a stator.

Description
