Insulating wear-resistant anti-corrosion multifunctional coating for track and preparation method thereof

Abstract

The invention relates to an insulating wear-resistant anticorrosive paint for tracks, which is prepared by adding silicon carbide, ultrafine aluminum oxide, iron oxide red, precipitated barium sulfateand the like as fillers into a flexible epoxy resin system and carrying out high-speed dispersion, grinding and ultrasonic treatment, and has the characteristics of high insulativity, excellent wearresistance, excellent salt spray resistance and easiness in construction. The stray current suppression effect and the corrosion resistance of the steel rail are greatly improved, and the steel rail can be applied to tramcar rails, subway rails, railway rails and the like, can also be popularized and applied to ship and ocean engineering steel structures, and has high economic value and wide prospects.

Description

technical field

[0001] The invention relates to the technical field of functional coatings, in particular to an insulating, wear-resistant and anti-corrosion multifunctional coating for rails and a preparation method thereof. Background technique

[0002] Tram tracks and subway tracks are prone to stray currents during operation, which not only consumes electrical energy, but also easily leads to electrochemical corrosion of metal structures near the tracks (such as gas pipes, water supply pipes, etc.). When the electrochemical corrosion is serious, it can cause damage to the pipe wall near the track, resulting in air leakage, water leakage and other consequences. At the same time, the locomotive rail itself is also prone to rust, which affects its service life. In order to suppress the stray current of the locomotive track, the existing technology mainly adopts the scheme of wrapping the rail with flexible material, but a large number of cracks will appear in the joints of ...
