Abstract

The invention discloses a damping material for making a rail backing plate of a high-speed railway and a preparation method thereof. The damping material for making the rail backing plate of the high-speed railway is prepared from the following ingredients in parts by weight: 30-50 parts of phenol-formaldehyde resin, 10-15 parts of phenolic resin, 30-50 parts of silicon rubber, 10-15 parts of styrene butadiene rubber, 10-15 parts of white carbon black, 2-3 parts of coupling agent KH550, 2-3 parts of crosslinker UN557, 5-10 parts of stearic acid, 1-2 parts of benzoyl peroxide, 0.2-1.0 part of cerous sulfate and 10-15 parts of argil. The material disclosed by the invention can be used for making the rail packing plate of the high-speed railway and has good damping and buffering performance, so that trains are lower in vibration and are more comfortable during running; furthermore, the material further has the advantages of deformation recovery capability, high deformation recovery speed and excellent fatigue resistance.

Description

technical field [0001] The invention relates to high-speed rail-related materials and equipment, in particular to a shock-absorbing material for making high-speed rail track pads and a preparation method thereof. Background technique [0002] With the rapid development of my country's high-speed railway, the operating mileage of high-speed railway continues to increase. High-speed rail has the advantages of fast speed, large transportation capacity, energy saving and comfort, and is the best choice to solve urban traffic problems. [0003] However, high-speed rail has brought many environmental problems along the line, especially problems such as vibration and noise, which have seriously affected the normal life of passengers and people along the track. On the other hand, noise and vibration may also cause fatigue of the train's own equipment and surrounding buildings, shortening the service life. In response to the above problems, technicians have carried out in-depth res...
