Abstract

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.

Description

technical field [0001] The invention belongs to the field of a pantograph carbon slide plate and its preparation, and in particular relates to a high-speed iron pantograph carbon slide plate and a preparation method thereof. Background technique [0002] The electrification and high-speed of railways are the development trend of railway transportation in the world at present. With the rapid development of China's economy, China's railway electrification construction has also entered a new period of development, and at the same time put forward higher requirements for the pantograph-catenary system. The pantograph-catenary system is the main source of power for the operation of electrified trains. It is mainly composed of catenary and pantograph. Development has gone through a long and complex process. In the research and application of pantograph slides, its materials have mainly experienced the development process of pure metal slides, powder metallurgy slides, pure carbo...
