Embodiment 1

[0031] A brake shoe body preparation material for a synthetic brake shoe of a high-power railway locomotive, which is composed of components in the following weight ratio: 10g per part

[0032] 9 parts of nitrile rubber, 5 parts of phenolic resin, 8.5 parts of sepiolite, 21 parts of iron powder, 3.5 parts of steel wool fiber, 0.4 part of bauxite, 12 parts of composite fiber, 16.5 parts of barium sulfate, 14 parts of graphite, potassium long 5.5 parts of stone, 0.5 parts of accelerator, 0.4 parts of zinc oxide, 0.4 parts of stearic acid, and 0.8 parts of sulfur.

[0033] The preparation method of the brake shoe body is as follows: Weigh the nitrile rubber of the specified weight, after the rubber is broken, add other ingredients of the specified weight in sequence: phenolic resin, sepiolite, iron powder, steel wool brazing fiber, bauxite, compound Fiber, barium sulfate, graphite, potassium feldspar, accelerator, zinc oxide, stearic acid, sulfur, then kneading, crushing, and fin...

Embodiment 2

[0037] A brake shoe body preparation material for a synthetic brake shoe of a high-power railway locomotive, which is composed of components with the following weight ratios:

[0038] 9.6 parts of nitrile rubber, 4.3 parts of phenolic resin, 9 parts of sepiolite, 22.3 parts of iron powder, 3.7 parts of steel wool fiber, 0.5 part of bauxite, 12.2 parts of composite fiber, 16 parts of barium sulfate, 14.9 parts of graphite, potassium long 5.8 parts of stone, 0.4 parts of accelerator, 0.3 parts of zinc oxide, 0.2 parts of stearic acid, and 0.8 parts of sulfur.

[0039] The preparation method of the brake shoe body is the same as that described in Example 1.

Embodiment 3

Abstract

The invention relates to a railway locomotive synthetic brake shoe preparation technique, particularly a brake shoe body preparation material which is prepared from the following components in parts by weight: 9-10 parts of nitrile-butadiene rubber, 4-5 parts of phenol aldehyde resin, 8-10 parts of meerschaum, 21-23 parts of iron powder, 3-4 parts of steel wool fiber, 0.3-0.8 part of bauxite, 11.5-12.5 parts of composition fiber, 15-17 parts of barium sulfate, 14-15.5 parts of graphite, 5-6 parts of potash feldspar, 0.2-0.7 part of accelerator, 0.1-0.5 part of zinc oxide, 0.1-0.5 part of stearic acid and 0.5-1 part of sulfur. The invention develops the friction material for Chinese railway HXD2 locomotives and forms the manufacturing technique of the friction material for Chinese CRH locomotives. The novel brake shoe can substitute imported products to satisfy the braking requirements of Chinese railway high-power locomotives.

Description

technical field [0001] The invention relates to a preparation technology for a synthetic brake shoe of a railway locomotive, in particular to a preparation material and a preparation method of a brake shoe body. Background technique [0002] my country's Harmony high-power locomotives are manufactured from GE of the United States, EMD of the United States, Toshiba of Japan, Alstom of France, and Siemens of Germany through introduction, digestion and re-innovation. The friction materials used in the braking system of the locomotive are mainly imported from abroad. There is no mass supply. Since the manufacturers are from North America, Europe, Japan and other countries and regions, the standards adopted are also different, and there is no evaluation system in China. Currently for HXD 2 Brake shoes for locomotives have not yet formed a complete manufacturing technology in China. A scientific and technological novelty search was conducted at the Shanxi Provincial Institute of ...
