Abstract

The invention relates to wheel track dry type lubricant that belongs to wheel track lubricant technology field and is mainly for reducing the abrasion of wheel track. It contains the following ingredient: 30-32% synthetic resin and polymerized oil, 38-40% soft metal, metal oxide, layer state material and high polymer, 6-8% extreme pressure anti-wear additive, 10-12% film forming assistant agent, 1-2% rare earth component, and 6-8% IPNs. The invention has high anti-extreme pressure property, strong adhesive capacity and good abrasion reducing effect. It is especially suited for lubricating bandy steel track.

Description

[0001] Field [0002] The invention relates to the technical field of wheel-rail lubrication, in particular to a wheel-rail dry lubricant. Background technique [0003] For a long time, train wheels and rails have been in a state of dry friction between steel and steel. As a result, not only the driving noise is loud, the wear of the rails and wheels is aggravated, not only the maintenance cost is increased, but also the dynamic performance of the vehicle is reduced. This situation is more prominent at the curved rail. Over the years, domestic and foreign railway science and technology workers have shown that among various technical measures to slow down the wear of curved rails, rail lubrication is a technical measure that is easy to operate and has obvious effects, and various methods are used to oil curved rails. Lubrication, such as: artificial oiling, ground oiler, oiling trolley, etc., all use grease as lubricating material, which plays a certain role in reducing fricti...
