Abstract
The invention discloses a solid lubricating, friction-reducing and repairing agent with efficacies of lubricating, reducing friction and in-situ repairing. The solid lubricating, friction-reducing and repairing agent comprises 100 parts of rubber, 3-4 parts of vulcanized rubber composition, 5-10 parts of sub-nanometer silicate powder, 2.5-10 parts of solid lubricating agent and 0.05-0.2 part of coupling agent. A preparation method comprises the steps of: (1) preparing materials according to the ratio in claim 1; (2) wrapping the sub-nanometer silicate powder which is dried in vacuum by the coupling agent, wherein the temperature is 70-80 DEG C; (3) milling the rubber in an open mill; (4) mixing the vulcanized rubber composition in the open mill; (5) putting the powder obtained from the step (2) into the open mill to mix; (6) adding the solid lubricating agent in the rubber open mill and mixing, and (7) controlling the temperature of cooling water in an open mill jacket below 60 DEG C until the materials are uniformly mixed, and cutting into strips of 5-8 mm. The solid friction-reducing agent can be coated on a wheel rail through a dispenser.
Description
technical field [0001] The invention relates to a wheel-rail solid lubricating anti-friction repairing agent, and also relates to a preparation method and application of the wheel-rail solid lubricating anti-friction repairing agent. Background technique [0002] When railway trains, subways, and urban rail vehicles are running, the rims and rails are always in contact, resulting in serious wear and tear on the rims, wheel rails, and labor-intensive wheel-rail maintenance has become an important problem that needs to be solved urgently. However, the use of diesel locomotives, electric locomotives, speed-up, and small-radius tracks have caused wheel-rail wear to become more and more serious. Chinese patent application CN201023482Y proposes a friction-reducing lubricating rod with graphite as the base material and a hole in the middle filled with grease. Some people also propose a lubricating rod with thermoplastics as the base material and graphite powder mixed in. But the a...
