The invention discloses a high-speed rail pantograph carbon contact strip and a preparation method thereof, belongs to the field of pantograph carbon contact strips and preparation thereof, and aims to solve the technical problem that an existing high-speed rail pantograph carbon contact strip is short in service life. The high-speed rail pantograph carbon contact strip is prepared from the following components in parts by mass: graphite powder, pitch coke powder, pitch, silicon carbide and modified molybdenum disulfide. The modified molybdenum disulfide is molybdenum disulfide obtained through granulation treatment. The preparation method comprises the following steps: step 1, mixing materials; step 2, extrusion molding; step 3, roasting treatment. The contact strip is reasonable in raw material composition and scientific in formula, and the prepared high-speed rail pantograph contact strip is excellent in wear resistance, good in electrical conductivity, long in service life, capableof well meeting various requirements of the high-speed rail pantograph carbon contact strip and wide in application range.
