Abstract
The invention discloses a kind of degradable wheel-rail friction regulators and preparation method thereof, it is made of the raw material below according to parts by weight: 20-40 parts of polylactic acid, starch plastic 30-50 points, crotonaldehyde 15-30 points, water 20-50 points, 15-45 parts of the hydrosol, the present invention is improved for the drawbacks of existing regulator, devise a kind of traction and braking that can both guarantee train well, reduce the superfluous situation of friction as much as possible again, reduce abrasion and the wave mill of rail and wheel, and over time, this regulator oneself can degrade, so as to avoid the pollution to environment, meet the requirement of environmental protection.
Description
Technical field
The present invention relates to coefficient of friction regulation technology field, specifically a kind of degradable wheel-rail friction regulator and its system
Preparation Method.
Background technique
Compared with atmospheric environment, be air-dried in railway tunnel, humidity it is low.Railway wheel is run under dry condition
When, adhesion coefficient (tangential force of wheel track interface transmitting and the ratio of vertical load weight the are defined as adhesion coefficient) phase at wheel track interface
It is larger to higher namely between driving wheel tyre tread and rail contact surface frictional resistance (adhesion), the abrasion of rail and wheel and wave
For mill (waveform of rail is worn away) than more serious, this will also result in the formation and fast development of railway wheel polygon.Use wheel
Rail solid lubricant or lubricating grease can be such that adhesion coefficient is reduced to 0.1 hereinafter, wheel rim and rail side can be effectively reduced
Abrasion.Due to the needs of train braking and traction, the adhesion coefficient between wheel tread and rail rail level cannot be below 0.2；It is glutinous
