Graphite lubricating material, lead-free copper-based pantograph slide and preparation method thereof

Abstract

The application discloses a kind of graphite lubricating material, lead-free copper-based pantograph slide and preparation method thereof, belong to rail transit vehicle accessory field.The graphite lubricating material includes base material and graphite strip;The base material includes copper base material, and a plurality of long slot is formed on the copper base material, and perpendicular to the movement direction;Graphite strip includes copper foil layer and graphite-based powder arranged in the copper foil layer, and the copper foil layer and graphite-based powder are formed by pressing, sintering integral part.The graphite strip of the application is formed by copper foil wrapping graphite-based powder, pressing, sintering integral part, so that the graphite strip has better structural strength, can be processed to form graphite strip with higher aspect ratio, and is arranged perpendicular to its movement direction, which not only can form continuous lubricating surface, thereby improving lubricating effect, but also reduces the number of graphite strip, thereby reducing the difficulty of assembly process.
