Copper-impregnated carbon sliding plate and preparation method thereof |
| abstract |
The invention discloses a copper-impregnated carbon sliding plate which is prepared from a basic raw material and an infiltration auxiliary agent; the basic raw material comprises 20-30 parts of asphalt coke; 10-15 parts of petroleum coke; 15-20 parts of flake graphite; 2-5 parts of carbon fiber; 10-20 parts of a binder; 5-10 parts of pore-forming agent. According to the invention, the components of the carbon sliding plate composite material are optimized, the bamboo charcoal powder is used as a pore forming agent, the impurity retention in pores is reduced, and the copper-containing carbon sliding plate can be formed by infiltrating copper liquid into the pores through a high-pressure copper leaching process, so that the carbon sliding plate has good mechanical property and electrical property. |
