Abstract

A liquid lubricating antifriction repairing agent for a wheel / rail having the effects of lubrication, friction prevention and in-situ repair comprises 50-60 parts of resin, 40-50 parts of curing agent, 5-10 parts of grease, 6-15 parts of sub-nanometer scale silicate powder, 4-10 parts of lubricant and 0.05-0.2 part of coupling agent. A method for preparing the liquid lubricating antifriction repairing agent for the wheel / rail is further provided, and the method comprises the following steps of: (1) preparing the resin, the curing agent, the grease, the sub-nanometer scale silicate powder, the lubricant and the coupling agent in accordance with proportions according to claim 1; (2) covering the sub-nanometer scale silicate powder with the coupling agent at a covering temperature ranging from 80 to 90 DEG C; (3) mixing the curing agent with the grease; (4) mixing the substance obtained in the step (2) with the mixture obtained in the step (3); (5) mixing the lubricant with the mixture; (6) mixing the resin with the mixture, wherein the time of mixing the resin is controlled within 15-20 minutes; and (7) pouring the mixture in a die for curing and formation. The repairing agent can be coated on the rim of the wheel through a filler.

Description

technical field [0001] The invention relates to a wheel-rail liquid lubrication anti-friction repairing agent, and also relates to a preparation method and application of the wheel-rail liquid lubrication 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...
