Carbon contact strip of pantograph and manufacturing method thereof
The invention discloses a carbon contact strip of a pantograph and a manufacturing method thereof. The carbon contact strip is prepared from following raw materials, by weight, 28-43 parts of petroleum coke powder, 25-28 parts of asphalt coke powder, 10-12 parts of sprayed carbon black, 2-5 parts of sulfur, 3-5 parts of boron nitride, 5-8 parts of carbon fiber, 4-6 parts of natural graphite, 5-7 parts of artificial graphite, 1-3 parts of calcium chloride powder and 30-35 parts of modified asphalt. The carbon contact strip is high in mechanical strength, is good in self-lubricating performance and electric arc resistance and is wear-resistant. The carbon contact strip can be not only used in various locomotives in railway main lines with speed per hour being 120-250 km/h, but also used in motor train units and high-speed trains with speed per hour being higher than 250 km/h. The carbon contact strip is free of limit of environment and climate conditions.
