The invention discloses an
electric locomotive pantograph carbon
slide plate, which is made of the following raw materials in parts by weight: 4.3-6.3 parts of semi-reinforcing
hydrocarbon black, 1.5-3.5 parts of 398 crystalline
flake graphite, 0.8-2.8 parts of 599 crystalline
flake graphite, 0.5-1.5 parts of
charcoal powder, and 4.6-6.6 parts of melting
coal pitch. The preparation method comprises technical steps of: hot mixing, rolling,
grinding, pressing,
roasting, impregnating, graphitizing, rough
machining, impregnating, solidifying, finish
machining, impregnating, bonding by
adhesive, solidifying and product inspecting. The
electric locomotive pantograph carbon
slide plate has the advantages of unique wear resisting and self-lubricating performance; low resistivity, small bonding resistance, strong ability for inhibiting spark, and good current
carrying capacity, thus being suitable for working condition of high power and
high current; uniform and compact structure, relatively high
mechanical strength and
impact resistance; and good
corrosion resistance, thus being suitable for working in various environmental and climate conditions.
