Problems solved by technology

Its materials have mainly experienced the development process of pure metal slides, powder metallurgy slides, graphite slides, metal-impregnated carbon slides, metal matrix composite slides and inorganic non-metal matrix composite slides, etc., but there are deficiencies in some performances. Metal or immersion metal and powder metallurgy and other skateboard materials have relatively high hardness, which generally has a high affinity for metal contact wires, which is easy to cause adhesive wear and serious wear of contact wires; graphite slide boards have large resistivity, small collection capacity, and poor impact resistance; Carbon fiber reinforced carbon skateboard has both high strength and wear resistance, but there are disadvantages such as high cost and long cycle of manufacturing carbon fiber

Embodiment Construction

[0016] This material preparation method comprises the following steps:

[0017] 1. Selection and preparation of raw materials: select 0.2-0mm particle size pitch coke 30%, 200 mesh pitch coke 45%, 325 mesh graphite powder 20%, ultra-fine reinforcing body carbon black 5%, high temperature hard pitch bonding Agent 35%.

[0018] 2. Green body molding: Pitch coke, carbon black and graphite powder of different particle size and purity after crushing, screening and grinding, totaling 300Kg, poured into a 1000L kneading pot, heated with heat transfer oil and stirred for 60min to 110-120 ℃, mix the materials evenly, add 108kg of asphalt binder that has been melted and dehydrated at 155-160 ℃, and stir for 60 minutes until the temperature reaches 150-155 ℃. , to prevent cooling and agglomeration, and then add a 315T vertical extrusion molding machine to control the mouth temperature, extrusion pressure and pressure speed, extrude at a uniform speed, and place in cooling water to cool....

Abstract

The invention relates to a pantograph slide plate material for a locomotive and a preparation method thereof and belongs to the technical field of materials. The preparation method of the pantograph slide plate material comprises the following steps: selecting pitch coke with high crushing resistance as aggregate, selecting graphite powder with good lubricating property, good electricity-conducting property and good heat-conducting property, then adding hard additive carbon black in a certain ratio, stirring, mixing, moulding, roasting, dipping and processing under the action of a high-strength and high-residue binder, so that the pantograph slide plate material with excellent performances is obtained, and an economic and practicable novel material with low specific resistance, good anti-attrition self-lubricating property and high strength is realized.

Description

technical field [0001] The invention relates to a pantograph sliding plate material for a railway locomotive and a preparation method thereof, belonging to the technical field of material preparation. Background technique [0002] With the rapid development of railway electric locomotives, especially the rapid development of electric locomotives in high speed or heavy load in recent years, with the continuous increase of train speed, higher requirements are put forward for the comprehensive performance of pantograph slides. Its materials have mainly experienced the development process of pure metal slides, powder metallurgy slides, graphite slides, metal-impregnated carbon slides, metal matrix composite slides and inorganic non-metal matrix composite slides, etc., but there are deficiencies in some performances. Metal or immersion metal and powder metallurgy and other skateboard materials have relatively high hardness, which generally has a high affinity for metal contact wi...
