High-hardness high-abrasion-resistance motor carbon brush material mixed with cubic boron nitride and preparation method of material
The invention relates to the field of carbon brush materials, in particular to a high-hardness high-abrasion-resistance motor carbon brush material mixed with cubic boron nitride and a preparation method of the material. According to the carbon brush material, high-purity conductive graphite and conductive carbon black serve as base materials, and conductivity is good. Liquid polysulfide rubber liquid rosin resin and an epoxy resin solution serve as a composite adhesive, the toughness of the adhesive is good, the adhesive and the conductive base materials have good compatibility and adhesive ability, and forming speed is high. Cubic boron nitride fine powder mixed into the material effectively improves hardness and abrasion resistance of the carbon brush material. Added nanometer aluminum oxide and lanthanum oxide have the effect of assisting in sintering. The sintered material is compact in structure and high in smoothness. A prepared carbon brush is good in steering performance, few in sparks, low in noise, more efficient and more durable.
