Embodiment 1

[0012] Wear-resistant protective ointment for railway wheels and rails, consisting of the following raw materials in parts by weight: mineral oil 50-68, stearic acid 4-16, molybdenum disulfide 2-16, graphite 5-15, dicyandiamide polymerization 2-11, polytetrafluoroethylene 1-5, boron nitride 1-5, rare earth fluoride 0.5-5, antimony trioxide 1-3, epoxy resin 2-8, magnesium oxide 1-4.

Embodiment 2

[0014] The wear-resistant ointment used for railway wheel rails is preferably composed of the following raw materials in parts by weight: mineral oil 56, stearic acid 10, molybdenum disulfide 10, graphite 11, dicyandiamide polymer 7, polytetrafluoroethylene 3, boron nitride 3, rare earth fluoride 3.5, antimony trioxide 2.5, epoxy resin 4, magnesium oxide 2.5.

[0015] The above mineral oil can be selected from gear oil, cylinder oil or machine oil, and the addition of magnesium oxide can increase the wear resistance of the ointment to more than 700 minutes, which has significant practical value.

Abstract

The invention provides wear-resisting protective factice for a rail wheeltrack, comprising the following raw materials in parts by weight: 50-68 parts of mineral oil, 4-16 parts of stearic acid, 2-16 parts of molybdenum disulfide, 5-15 parts of graphite, 2-11 parts of dicyandiamide polymer, 1-5 parts of polytetrafluoroethylene, 1-5 parts of boron nitride, 0.5-5 parts of rare earth fluoride, 1-3 parts of antimony trioxide, 2-8 parts of epoxy resin and 1-4 parts of magnesium oxide. In the invention, due to the addition of the magnesium oxide, the wear resistance of the factice is improved by 700min, and the wear-resisting protective factice has a remarkable practical value.

Description

technical field [0001] The invention belongs to the technical field of lubricants, and in particular relates to a wear-resistant protective ointment for railway wheel rails. Background technique [0002] At present, there are roughly two types of wheel-rail lubricants used at home and abroad, one is lubricating oil, and the other is grease. Due to the harsh working conditions of the wheel and rail, in addition to the interaction between the wheel and rail, it is also affected climate impact. Although the grease lubricant partially improves the wear of the wheel and rail, it is difficult for the grease lubricant to form a good lubricating oil film under the load of up to several tons per square centimeter and rigid impact, polarization, torsional vibration, sliding, etc., even if formed The oil film, too, is quickly destroyed by the interaction between the wheel and the rail. In summer, sunlight will cause the grease remaining on the rails to lose quickly. At the same time,...
