Problems solved by technology

Due to the low bonding strength between graphite and pitch carbon, there are many micro-cracks inside the product, the flexural strength and impact strength are low and easy to break, the resistivity is too high and easy to generate heat, which leads to performance degradation and other problems, resulting in poor product performance. Stable, high defective rate, difficult to achieve mass production

Embodiment 1

[0029] The intercalated graphite added to the carbon fiber reinforced pantograph carbon slide plate in this example is a copper-graphite intercalation compound.

[0030] The preparation of the copper-graphite intercalation compound includes the following steps:

[0031] 1. Mix the natural flake graphite and anhydrous copper chloride at a molar ratio of 2:3 and add them into a stainless steel pressure tank.

[0032] 2. Seal the stainless steel pressure tank and place it in a pit furnace, and heat it to 450-550°C at a heating rate of 2°C / min. After the heat preservation reaction for 72 hours, the temperature will be naturally cooled to room temperature to obtain copper chloride-graphite interlayer Compound.

[0033] 3. Spread the copper chloride-graphite interlayer compound in a stainless steel tray and place it in a hydrogen reduction furnace. After evacuating to 0.1MPa, add hydrogen at a flow rate of 1 to 2L / min, and at the same time press 1℃ / min The heating rate is heated to 450~500...

Embodiment 2

[0043] Others are the same as Example 1, except that intercalated graphite is 30% (weight ratio), petroleum coke is 40% (weight ratio), carbon fiber is 5% (weight ratio), and medium temperature pitch is 25% (weight ratio).

Embodiment 3

[0045] Others are the same as in Example 1, except that intercalated graphite is 50% (weight ratio), petroleum coke is 20% (weight ratio), carbon fiber is 2% (weight ratio), and medium temperature pitch is 28% (weight ratio).

Abstract

The invention discloses a carbon fiber reinforced pantograph carbon sliding plate and a manufacturing method thereof. The carbon fiber reinforced pantograph carbon sliding plate contains intercalation graphite. The carbon fiber reinforced pantograph carbon sliding plate comprises the following materials in percentage by weight: 30-60% of intercalation graphite, 8-32% of petroleum coke, 2-16% of carbon fiber, and 15-35% of medium temperature asphalt. Compared with the prior art, the carbon fiber reinforced pantograph carbon sliding plate disclosed by the invention has the advantages of low electrical resistivity, high mechanical strength, good comprehensive properties such as electrical conductivity, abrasion resistance and self-lubricating property and the like; through test, the carbon fiber reinforced pantograph carbon sliding plate comes up to the foreign advanced technical level; according to the invention, the manufacturing method is simple, and the properties of the product are stable, therefore, the large-scale production can be realized.

Description

Technical field [0001] The invention belongs to the technical field of electric locomotives, and particularly relates to a carbon fiber reinforced pantograph carbon skateboard and a manufacturing method thereof. Background technique [0002] Electric traction high-speed trains are in continuous frictional contact with the catenary wire through the pantograph carbon slide system to guide the current on the grid and transmit it to the locomotive power system to maintain the normal operation of the electric locomotive. The pantograph carbon slide plate is an electrical contact material that integrates high electrical conductivity, abrasion resistance and anti-friction performance. It must have good electrical conductivity and current collection capability, but also match the pantograph-net coupling system. Therefore, The relationship between the pantograph slide plate made of this material and the contact net wire forms a pair of special friction pairs coupled mechanically and elect...
