| titleOfInvention | Modified flake graphite powder, resin-based carbon brush and preparation method |
| abstract | The invention discloses modified crystalline flake graphite powder, a resin-based carbon brush and a preparation method thereof, wherein the modified crystalline flake graphite powder comprises crystalline flake graphite and tungsten alloy powder coated on the surface of the crystalline flake graphite, and the mass of the tungsten alloy powder is 5-15% of that of the crystalline flake graphite; the resin-based carbon brush comprises the following components in parts by mass: 70-80 parts of modified crystalline flake graphite powder, 20-30 parts of epoxy resin and 4-5 parts of curing agent. The modified flake graphite powder has the advantages of good dispersibility, and can be used as an additive to improve the abrasion resistance, mechanical strength, conductivity and arc ablation resistance of the material; the resin-based carbon brush has the advantages of proper electrical resistivity and thermal conductivity, good arc ablation resistance on a wear surface, high breaking strength and long service life. |
