Problems solved by technology

Although these antifriction agents can improve the wear of the wheel and rail, under the action of high load and rigid impact force, shear force, torsional vibration and sliding friction, the formed oil film will be quickly destroyed and carbonized by the mutual force. Serious oil wedge effect on rails is even more detrimental to driving safety, so it is necessary to improve

Abstract

The invention discloses an environment-friendly wheel-rail antifriction agent which is composed of the following raw material in parts by mass: 30-40 parts of poly-alpha-olefin, 20-30 parts of Doverphos 253 (dioleyl phosphonate), 4-8 parts of molybdenum disulfide, 6-12 parts of molybdenum N,N-bis(2-ethylhexyl)dithiocarbamate, 20-30 parts of 2,2,4-trimethyl-1,3-pentanediolmono(2-methylpropanoate),3-6 parts of monoalkenyl succinimide, 10-15 parts of lauryl acrylate, 5-10 parts of zinc dialkyl dithiophosphate and 10-20 parts of neopentyl polyol higher fatty acid ester. The wheel-rail antiattrition agent disclosed by the invention has the advantages of very good biodegradability, very good wear resistance, corrosion resistance, salt spray resistance and longer service life. A protective filmwith high-temperature-resistant and low-temperature-resistant effects can be formed on a wheel rail by the wheel-rail lubricating antifriction agent. When in use, the agent is convenient for sprayingconstruction, has stable performance, can be dried automatically, is non-toxic, harmless and biodegradable, and conforms to the requirements of environmental protection characteristics.

Description

Technical field [0001] The invention relates to a wear-reducing agent, in particular to an environment-friendly wheel-rail wear-reducing agent. Background technique [0002] Due to the harsh working conditions of the wheel and rail, the friction between the rail and the wheel is very complicated. There is side sliding friction between the wheel flange and the track, and there is also rolling friction on the tread. What is more serious is the contact fatigue caused by the contact between the wheel and the rail. , Microcracks are generated on the active surface of the rail. When the train is rolled, because there are liquid substances such as water, oil or grease on the surface of the rail, the instantaneous ultra-high pressure is formed under the high pressure shock load and friction state, causing the microcracks to develop further. If the microcracks are It can peel off in pieces after penetration. And due to high temperature and high pressure, rapid speed changes and vibration...
