Problems solved by technology

[0003] Although the use of friction control agents can effectively reduce the loss of rail transit and reduce economic losses, due to the late development of domestic rail lubrication research, in the early research, in order to ensure the adhesion factor between the wheel tread and the top surface of the rail, the lubricant The use is limited to the locomotive wheel rim and the side of the rail, and is generally only used in the curved section of the rail. The lubrication of the rolling surface was once considered a forbidden area in the field of rail lubrication

Description

technical field [0001] The invention belongs to the field of wheel-rail friction control, and in particular relates to a formula of a train wheel tread friction control agent based on an inorganic composite adhesive and a preparation method thereof. Background technique [0002] Wheel-rail friction is the most important energy consumption factor in railway transportation. Reducing the frictional resistance of wheel-rail can not only reduce the wear of wheel-rail, but also save energy and reduce emissions, which is in line with the national green development concept. Since the end of the 20th century, the problem of wheel-rail damage on heavy-haul railways has become increasingly prominent, seriously affecting the economic benefits and safety of railway transportation. In order to solve these problems, people began to try to control the friction of the wheel tread. [0003] Although the use of friction control agents can effectively reduce the loss of rail transit and reduce ...
