Abstract

The present invention discloses a carbon fiber reinforced pantograph carbon slide plate material and a manufacturing method thereof. The material comprises, by mass, 30-60% of a graphite intercalation compound, 8-32% of petroleum coke, 2-16% of carbon fibers, and 15-35% of medium temperature asphalt. Compared to the carbon fiber reinforced pantograph carbon slide plate in the prior art, the carbon fiber reinforced pantograph carbon slide plate of the present invention has advantages of low resistivity, high mechanical strength and the like, and has excellent comprehensive performances such as electrical conductivity, abrasion resistance, self-lubricating and the like, wherein international advanced technology levels are met with tests. In addition, the manufacturing method is simple; the stable product performance can be achieved; and large-scale production can be achieved.

Description

technical field [0001] The invention belongs to the technical field of electric locomotives, and in particular relates to a carbon fiber reinforced pantograph carbon slide material and a manufacturing method thereof. Background technique [0002] Electric traction high-speed trains use the pantograph carbon slide plate system to continuously rub against the catenary wires to guide the current on the grid and transmit it to the locomotive power system to maintain the normal operation of the electric locomotive. The pantograph carbon slide is an electrical contact material that integrates high conductivity, wear resistance and anti-friction performance. The relationship between the pantograph slide made of this material and the catenary wire constitutes a pair of special friction pairs that are mechanically and electrically coupled. [0003] Due to the long-term exposure of the pantograph carbon skateboard to the natural environment, it often works in dry, humid, even sandy, ...
