Problems solved by technology

At present, there are many kinds of modified components added to base oil, but it is difficult for various modified components to coexist so that their own performance can be fully exerted
At the same time, although the inorganic additives currently added to lubricating oils have significant modification effects, they have problems of uneven size and uneven dispersion.
In addition, the performance of the modified lubricating oil is difficult to maintain stably, and after a period of use, the performance of the lubricating oil will drop sharply

Embodiment 1

[0027] Dissolve sodium borate in distilled water to prepare solution A, dissolve lanthanum nitrate in absolute ethanol to prepare solution B, dissolve octadecyl pyridinium dithiophosphate (PyDDP) in alcohol aqueous solution, and heat to 80°C Stir until octadecyl dithiophosphate pyridinium salt is completely dissolved to obtain solution C, add solution A to solution C and mix well and keep warm at 80°C for 10 minutes, then add solution B dropwise, continue to react for 3 hours after the dropwise addition, and the reaction ends After standing still for 30 minutes, the temperature of the reaction solution was maintained at 80°C during the whole process, filtered while it was hot and washed with an alcohol solution of 80°C, and the washed product was dried in a vacuum drying oven to obtain modified nano-lanthanum borate. The alcohol aqueous solution is 80% ethanol solution, the mass ratio of lanthanum nitrate and octadecyl pyridinium dithiophosphate is 1:1, and the molar ratio of l...

Embodiment 2

[0029] Weigh sodium nitrate, sodium silicate and sodium hydroxide respectively according to the mass ratio of 2:1:30, import the weighed sodium nitrate, sodium silicate and sodium hydroxide into a beaker, add water and stir to dissolve, and dissolve the solution completely Heat to 200°C and keep it warm for 20 hours, then cool naturally to room temperature, centrifuge and filter to recover the reaction product, and alternately wash with deionized water and ethanol for 2 to 3 times (2 to 3 times refer to the total number of water washing and alcohol washing) to obtain product A , ultrasonically disperse product A into ethanol solution, then add silane coupling agent KH-560, heat to 60°C and stir for 90 minutes, the weight of silane coupling agent KH-560 added is half of the weight of product A, then naturally cool to At room temperature, centrifuge and filter to recover the reaction product, and wash with ethanol for 2 to 3 times to obtain modified nano-magnesium silicate.

Embodiment 3

[0031] The total weight of lubricating oil is 100 parts by weight, including 4 parts by weight of dispersants, 3 parts by weight of viscosity modifiers, 0.75 parts by weight of antiwear agents, 0.3 parts by weight of wear reducers, 0.05 parts by weight of detergents, and the balance as base oil.

[0032] The anti-wear agent is prepared from zinc dialkyldithiophosphate, modified nano-magnesium silicate, and modified nano-lanthanum borate according to the weight ratio of 4:10:1; the mass of oil-soluble organic molybdenum and modified nano-lanthanum borate The ratio is 6:1; the dispersant is polyisobutenyl succinimide; the viscosity modifier is polymethacrylate PMA; the detergent is TBN400; the oil-soluble organic molybdenum is molybdenum dialkyldithiophosphate; The oil is polyalphaolefin synthetic base oil.

[0033] Above-mentioned lubricating oil adopts following method to obtain:

[0034] Accurately weigh each component according to the ratio of lubricating oil, first add th...

Abstract

The invention relates to a lubricating oil. The lubricating oil comprises, by weight, 4-4.5 parts of a dispersant, 2-3 parts of a viscosity modifier, 0.5-0.8 part of an anti-wear agent, 0.2-0.3 part of a wear reducer, 0.05-0.1 part of a detergent, and base oil, and the total weight part is 100. The effect of the compatibility of all modification components is far better than the superposed effect of individual modification components in affection of the performances of the base oil, so the wear resistance and the dispersion performance of the lubricating oil are remarkably improved.

Description

technical field [0001] The present invention relates to a lubricating oil. Background technique [0002] Lubricating oil is composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil. Additives include various modifying components, which modify different properties of the base oil. At present, there are many kinds of modified components added to the base oil, but it is difficult for various modified components to coexist so that their own performance can be fully exerted. At the same time, although the inorganic additives currently added to lubricating oils have significant modification effects, they have problems of uneven size and uneven dispersion. In addition, the performance of the modified lubricating oil is difficult to maintain stably, and after a period of use, the performance of the lubricating oil will drop signific...
