Embodiment Construction

[0024] The following will be attached Figure 1~2 Examples further describe the present invention.

[0025] according to figure 1 The preparation process of carbon fiber materials is carried out, and pitch-based carbon fiber precursors are used as raw materials. The price of pitch-based carbon fiber precursors is low, the carbon content is high, and the preparation process is simple, easy to purchase and store, and the pitch-based carbon fiber precursors The silk contains oil, the friction coefficient is small, the electrical conductivity is good, and it also has the advantages of oxidation resistance, high temperature resistance, acid and alkali resistance, etc., so that the prepared carbon fiber material has good performance in electrical conductivity and wear resistance, and is very suitable for the role of affected people. Prepare raw materials for electrolytic slides.

[0026] Oxidize and carbonize the purchased pitch-based carbon fiber precursors to obtain carbon fiber...

Abstract

The invention discloses a carbon fiber material and a preparation method and an application thereof. By taking asphalt-based carbon fiber precursors as a raw material, the material is oxidized and carbonized to obtain the carbon fiber material. The preparation process is simple, and the prepared carbon fiber material has the characteristics of being low in friction coefficient, high in wear resistance and high in conductivity. A pantograph slide block is prepared from the carbon fiber material prepared from the asphalt-based carbon fiber precursors. The pantograph slide block is prepared directly from the asphalt-based carbon fiber precursors without a carbon dust pressing process. Although the cost of the raw materials is relatively increased by the novel method, the prepared pantograph slide block is long in service life, high in safety performance, high in reliability and higher in cost performance, and can fully meet the using demand that the pantograph of a locomotive is in contact with an electrified wire net to slide. The invention also provides a method of preparing the pantograph slide block.

Description

technical field [0001] The invention relates to a carbon fiber material, a preparation method and an application thereof, which are used for preparing a locomotive pantograph slider, and belong to the field of material science. The invention also relates to a method for preparing a pantograph slider. Background technique [0002] At present, the main locomotives in my country are still electric locomotives, that is, the power grid supplies power to the locomotives. The power supply voltage of the power grid is as high as 27.5 KV, and the operating current of the locomotive is as high as 200-300 A. Such a super-powerful power supply is obtained from the power grid through the high-speed gliding pantograph when the train is running at high speed. In order to reduce the damage to the grid due to friction, and for the sake of less wear and long life of the pantograph, when the pantograph is raised, it must ensure a certain contact pressure on the grid, so the pantograph slider ...
