Problems solved by technology

[0004] 1. The maintenance cycle of engine oil is short: it is usually applied once every 5 days (the application cycle of some electric service sections is even shorter as 2-3 days, and it needs to be applied every day in rainy days), which leads to a very heavy labor intensity for daily maintenance
[0005] 2. The engine oil is not resistant to rainwater erosion: the engine oil will be washed away by the rainwater immediately after lubrication, losing its lubricating and protective effect on the switch
[0006] 3. Poor anti-rust ability of engine oil: long-term use will cause serious rust on the turnout slide, and the severely rusted slide will not work normally
[0007] 4. Poor extreme pressure resistance and lubricating ability of engine oil: on some heavy-duty slides, the coefficient of friction will increase sharply, increasing the working resistance and wear of the turnout slides
[0008] 5. Engine oil is not biodegradable: long-term use will cause pollution and damage to the environment and human body

Embodiment 1

[0030] Add 50 g of 2-hexyldecyl oleate, 40 g of 2-hexyldecyl linoleate, 9 g of regenerated waste mineral oil and 1 g of surface-modified polytetrafluoroethylene into a stirring tank, and stir at room temperature for 15 minutes to obtain lubricating oil composition I . Properties are listed in Table 1.

Embodiment 2

[0032] Add 80 g of 2-octyl dodecyl oleate, 10 g of 2-octyl dodecyl linoleate, 5 g of regenerated waste mineral oil and 5 g of surface-modified polytetrafluoroethylene into the stirring tank, and stir at room temperature for 20 min. Lubricating oil composition II was obtained. Properties are listed in Table 1.

Embodiment 3

[0034] 60g of 2-decyltetradecyl oleic acid ester, 30g of 2-decyltetradecyl linoleic acid, 8g of regenerated waste mineral oil and 2g of surface-modified polytetrafluoroethylene were added to the stirring tank, and stirred at room temperature for 40min to obtain Lubricating Oil Composition III. Properties are listed in Table 1.

Abstract

The invention discloses a turnout junction lubricating oil composition. The turnout junction lubricating oil composition is prepared from the following components in parts by weight: 50 to 80 parts ofGolbert alcohol oleate, 10 to 40 parts of Golbert alcohol linoleate, 5 to 9 parts of regenerated waste mineral oil, and 1 to 5 parts of solid lubricating agent. Compared with the existing machine oilfor lubricating a railway turnout junction, the lubricating oil composition disclosed by the invention is excellent in degradability, good in viscosity-temperature performance and high / low temperature performance, good in abrasion reduction, wear resistance and rust resistance, and also capable of effectively recycling the waste and reducing the oil cost.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to a turnout lubricating oil composition and a preparation method thereof. Background technique [0002] The turnout is an important part on the railway line, and its normal operation is the basic guarantee of driving safety. Reducing the switching resistance of the switch point rail can improve the switching reliability of the switch point, and oil lubrication is one of the effective methods to reduce the friction between the point rail and the sliding bed plate. [0003] At present, machine lubricating oil is widely used in China, and there are the following defects (the application of lubricants in the lubrication of turnouts, http: / / www.jiancai365.cn / ypnews_83768.htm): [0004] 1. The maintenance cycle of engine oil is short: it is usually applied every 5 days (the application cycle of some electric service sections is even shorter as 2-3 days, and it needs to be appl...
