Abstract

The invention discloses a pantograph carbon slide plate. The pantograph carbon slide plate comprises the following raw materials in percentage by mass: 50 to 70 percent of graphite powder, 50 to 70 parts of corundum, 10 to 15 parts of carbon fiber, 20 to 30 parts of petroleum coke coarse powder, 20 to 30 parts of petroleum coke fine powder, 10 to 15 parts of high bauxite, 10 to 15 parts of asphaltadhesive, 5 to 10 parts of coal tar asphalt, 5 to 10 parts of copper powder and 5 to 10 parts of aedelforsite powder. The aedelforsite powder is added to the raw materials of the carbon slide plate,and the own characteristics of the aedelforsite powder are utilized, so that the surface expansion performance of the carbon slide plate is enhanced, cracks are reduced, the corrosion resistance, thedurability and the weather resistance are enhanced, and the structural shrinkage rate of the carbon slide plate during work is effectively reduced; the corundum material is adopted, so that the wear resistance of the carbon slide plate surface is guaranteed and the own thermal expansion rate of the carbon slide plate is reduced; the process is simple, low in requirement on equipment and high in operability, and has good social popularization application.

Description

technical field [0001] The invention relates to the technical field of carbon slides, in particular to a pantograph carbon slide and a preparation process thereof. Background technique [0002] Safety is the eternal theme of railway transportation production. Locomotives are the most important power equipment in railway transportation production. To provide locomotives with good quality and sufficient quantity for use, and to ensure the smooth completion of transportation tasks and the safety of transportation production with good equipment quality is the main task of locomotive maintenance work. [0003] The electric locomotive pantograph carbon skateboard is a "throat" component that provides power for high-speed rail, bullet trains, and passenger and freight electric locomotives. Work in a natural environment. Due to the constant friction and impact with the catenary wire during operation, this part is a consumable part that is frequently replaced. And because the tra...
