Problems solved by technology

[0002] At present, ordinary high-speed rail locomotive wheel rim lubrication adopts grease lubrication technology and liquid lubricant, which requires special supporting equipment, which has high cost and large consumption, does not meet the new requirements and new trends of environmental protection and energy saving, and the degree of technological innovation is not high.
And if the grease and oil Louis is damaged or blocked, it will cause insufficient lubrication of the locomotive wheel rim, resulting in different degrees of wear and tear, which is not conducive to the continuous and stable operation of the locomotive.

Embodiment 1

[0055] A locomotive rim solid lubricant, the raw material formula in parts by weight is as follows: 60 parts of molding resin, 24 parts of molybdenum disulfide, 1 part of halogen-free flame retardant, 7 parts of graphite, and 8 parts of aluminum oxide. According to the above formula, the raw materials are mixed into a mass by internal mixer, the mass is weighed and preformed, and the one-time filler is added to the mold to ensure that the cavity of the mold is filled, and then molded. Molding temperature: 160~180°C, pressure : 4~10MPa, time: 10~20min.

Embodiment 2

[0057] A locomotive rim solid lubricant, the raw material formula in parts by weight is as follows: 29 parts of molding resin, 41 parts of molybdenum disulfide, 5 parts of halogen-free flame retardant, 12 parts of graphite, and 13 parts of aluminum oxide. According to the above formula, the raw materials are mixed into a mass by internal mixer, the mass is weighed and preformed, and the one-time filler is added to the mold to ensure that the cavity of the mold is filled, and then molded. Molding temperature: 160~180°C, pressure : 4~10MPa, time: 10~20min.

[0058] Optionally, the molding resin is specifically at least one of epoxy resin, phenolic resin, polytetrafluoroethylene resin and unsaturated resin, and the effect is better when unsaturated polyester resin is selected.

[0059] As an optional mode, the particle size of the molybdenum disulfide is 2000 mesh (the smaller the particle size, the better), and the purity is above 95%. Molybdenum disulfide in the obtained mater...

Embodiment 3

[0064] A locomotive rim solid lubricant has the following raw material formula in parts by weight: 47 parts of molding resin, 30 parts of molybdenum disulfide, 3 parts of halogen-free flame retardant, 10 parts of graphite, and 10 parts of aluminum oxide. According to the above formula, the raw materials are mixed into a mass by internal mixer, the mass is weighed and preformed, and the one-time filler is added to the mold to ensure that the cavity of the mold is filled, and then molded. Molding temperature: 160~180°C, pressure : 4~10MPa, time: 10~20min. Exhaust air 2-3 times during molding.

Abstract

The invention discloses a locomotive rim solid lubricant and a preparation method thereof. The locomotive rim solid lubricant includes molded resin, molybdenum disulfide, halogen-free flame retardant, graphite and alumina. The lubricant is blocky, and can be directly attached to the rim of the locomotive when in use, and is convenient to use, reliable in performance, capable of fully lubricating the rime of the locomotive and durable; and dust generated by friction is environment-friendly and pollution-free.

Description

technical field [0001] The invention belongs to the field of lubricating materials for locomotive rims, in particular to a solid lubricant for locomotive rims and a preparation method thereof. technical background [0002] At present, ordinary high-speed rail locomotive wheel rim lubrication adopts grease lubrication technology and liquid lubricant, which requires special supporting equipment, which has high cost and large consumption, does not meet the new requirements and new trends of environmental protection and energy saving, and the degree of technological innovation is not high. And the oily oil Louis is damaged and blocked, then causes the locomotive wheel rim to lubricate insufficiently, causes the wearing and tearing of varying degrees, is unfavorable for the continuous and stable operation of the locomotive. Contents of the invention [0003] In view of the above problems, the present invention provides a solid lubricant for locomotive rims, which replaces greas...
