Abstract

The invention provides environment-friendly wheel and track lubricating grease. The environment-friendly wheel and track lubricating grease comprises, by weight, 70-95 parts of base oil, 1-20 parts of thickening agents, 1-8 parts of anti-wear agents, 0.05-3 parts of antioxidants, 0.02-1.5 parts of anti-corrosion and anti-rust agents and 1-10 parts of solid anti-wear materials. The base oil comprises ester oil and / or synthetic hydrocarbon. The environment-friendly wheel and track lubricating grease has the advantages that the white environment-friendly wheel and track lubricating grease is excellent in low-temperature performance, biodegradability, anti-corrosion property and extreme pressure anti-wear property and free of harmful elements such as heavy metal, is non-toxic (or is low in toxicity) and is easy to pump, spray and uniformly atomize; wear of flanges of wheels can be effectively reduced, the service lives of the wheels and steel tracks can be prolonged, environmental requirements can be met, and the environment-friendly wheel and track lubricating grease is applicable to lubricating the wheels and the tracks for track traffic in wide temperature ranges of -50-150 DEG C.

Description

technical field [0001] The present invention relates to an environment-friendly wheel-rail lubricating grease and a preparation method thereof, in particular to an environment-friendly cold-resistant wheel-rail lubricating grease used for lubricating wheels and rails in rail transportation fields such as railway locomotives and urban railway (subway) locomotives and rolling stock. its preparation method. Background technique [0002] Wheels and rails are unique friction pairs of rail transit. Solving the problem of wear between wheels and rails has been a difficult problem that has been studied and paid attention to by countries all over the world. Using a suitable wheel-rail lubricant is an effective way to improve the wear and tear between the wheel and rail. It plays an important role in reducing wheel and rail wear, prolonging the service life of the wheel and rail, reducing noise pollution, and reducing traction energy consumption. Save a lot of production and maintena...
