Embodiment 1
[0026] Example 1: Electric locomotive pantograph carbon slide plate, made of the following raw materials in parts by weight: 5.3 parts of semi-reinforcing carbon black, 2.5 parts of -398 flake graphite, 1.8 parts of 599 flake graphite, 1 part of charcoal powder and melted coal 5.6 parts of asphalt.
[0027] The process steps of the preparation method are: (1) Thermal mixing: Add the semi-reinforcing carbon black, -398 flake graphite, 599 flake graphite and charcoal powder in the above raw materials into a 500-liter kneader according to the weight ratio for thermal mixing, and heat Mix for 50-60 minutes, when the temperature is higher than 130°C, add melted coal tar pitch, then close the lid and heat mix for 2-3 hours, when the temperature reaches 170-180°C, unload;
[0028] (2) Rolled sheet: control the thickness of the rolled sheet within 2mm;
[0029] (3) Grinding: use 3R pendulum mill for grinding, control particle size: 240 mesh pass rate 55-75%;
[0030] (4) Pressing: u...

Abstract
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.
Description
technical field [0001] The invention relates to a pantograph carbon slide plate of an electric locomotive, which is suitable for the technical fields of urban rail transit, subway, and mining locomotives. Background technique [0002] Electric locomotive pantograph carbon skateboard is an important current-collecting part for locomotives to import electric energy. With the development of electrified railways and high-speed railways, the subject of reducing wear of railway catenary wires and improving the wear-resistant and self-lubricating properties of skateboards has always been an extremely important issue in the development of the world's railways. important research project. [0003] There are three main types of pantograph slides: powder metallurgy slides, carbon slides, and metal-impregnated carbon slides. Industrially developed countries have successively developed carbon slides to replace powder metallurgy slides, effectively reducing the wear on catenary wires and...
