Problems solved by technology

[0004] Therefore, in order to solve the lubrication problem of the track under high temperature conditions and solve the problem that the existing track grease is prone to failure under high temperature conditions, it is necessary to prepare a high temperature grease for the track, so that the grease has very good high temperature resistance and does not Coking and carbon deposition, no loss, can be used for track lubrication under ultra-high temperature conditions

preparation example Construction

[0026] The preparation method of the track high-temperature lubricating grease provided in this embodiment includes the following steps: after uniformly mixing the components according to the set weight percentage, heating to a temperature of 60-80°C, and then grinding to obtain the track high-temperature lubricating grease; It is preferable to uniformly mix the components according to the set weight percentage, heat to a temperature of 70°C, and then grind; this preparation method is simple to operate, requires few procedures, and the quality of the prepared lubricating grease is stable, with excellent oxidation resistance and high temperature resistance. Anti-wear performance, proper heating and grinding is beneficial to reduce the viscosity of grease, so that solid additives can be fully ground and dispersed.

[0027] In this embodiment, when preparing high-temperature lubricating grease for rails according to the preparation method, the colorant oil-soluble red is added in ...

Embodiment 1

[0031] Take 40% of polyisobutylene (average molecular weight is 2400), 18% of fumed silicon dioxide, 40% of boron nitride (1000 mesh), 2% of zinc oxide (800 mesh) and 100ppm of oil-soluble red in small test kettle by weight percentage After uniform mixing, heat to 80°C, and then put the heated mixture into a three-roll mill to grind until the solid additives are fully dispersed, and then the orbital high-temperature grease is obtained.

Embodiment 2

[0033] Take 15% of polyisobutylene (average molecular weight is 2400), 20% of fumed silicon dioxide, 60% of boron nitride (500 mesh), 5% of zinc oxide (500 mesh) and 10ppm of oil-soluble red in small test kettle by weight percentage After uniform mixing, heat to 70°C, and then put the heated mixture into a three-roll mill to grind until the solid additives are fully dispersed, and then the orbital high-temperature grease is obtained.

Abstract

The invention provides a rail high-temperature lubricant and a preparation method thereof; the rail high-temperature lubricant is prepared by mixing and grinding silicon dioxide, polyisobutene, boron nitride and zinc oxide. Polyisobutene is thickened by using a silica inorganic thickener to obtain a basic inorganic lubricant, boron nitride and zinc oxide are added, and the prepared lubricant may ensure rail lubrication under superhigh temperature, and the lubricant has good wear resistance at high temperature. All the materials used for the rail high-temperature lubricant have good properties; after adding, the materials can exert their excellent properties and are also synergic, and the finally produced lubricant has very excellent tolerance to high temperature, oxidation resistance and wear resistance. The rail high-temperature lubricant has simple composition, and has no need for adding other basic oil and additives; the preparation method of the rail high-temperature lubricant is simple and has few steps, product quality is stable, and monitoring is easy.

Description

technical field [0001] The invention relates to the field of lubricating grease, in particular to a track high-temperature lubricating grease and a preparation method thereof. Background technique [0002] With the continuous improvement of the level of industrialization, the operating temperature requirements of many lubricating parts are getting higher and higher, and higher requirements are also put forward for the high temperature resistance of lubricating grease. Most commonly used lubricating grease will soften, melt or volatilize at high temperature, and it is easy to drip and lose oil, thus losing its lubricating effect. [0003] Grease is usually divided into soap-based grease and non-soap-based grease, of which soap-based grease is the most commonly used grease, whether it is soap-based grease or non-soap-based grease, the grease itself is characterized by changes with temperature, The consistency of lubricating grease changes greatly, especially high-temperature ...
