Problems solved by technology

Modified organic molybdenum is often added to engine oil as a friction reducing agent, such as commonly used molybdenum dialkyldithiophosphate, molybdenum dialkyldithiocarbamate, molybdenum diisopropyldithiophosphate sulfide, di( 2-ethylhexyl) molybdenum oxysulfide dithiophosphate; but these organic molybdenum modifiers used in the market all contain sulfur and phosphorus elements, which will produce harmful substances and corrode metals during use

Embodiment 1

[0039] 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

[0041]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

[0043] Dissolve 200g of coconut oil acid chloride and 100g of pyridine in petroleum ether, stir and dissolve at 25°C, then add 80g of diethanolamine dropwise under stirring conditions, react for 4.2h at 25°C after the dropwise addition, and filter the reaction solution to recover organic matter after the reaction Components, the recovered organic components are washed 2 to 3 times with sodium bicarbonate solution (mass fraction 5%), then back-extracted with ethyl acetate and separated to obtain the water phase, and anhydrous magnesium sulfate is used to absorb the water phase. Moisture content obtains the organic phase component, and then the solvent in the organic phase component is evaporated under reduced pressure to obtain the organic compound A;

[0044] Dissolve 100 parts by weight of organic compound A in N,N-dimethylformamide, then add 2 parts by weight of triethylamine, stir and heat to 100°C, then add 150 parts by weight of molybdic acid with a mass fraction of 15% dr...

Abstract

The invention relates to lubricating oil. The lubricating oil comprises, by weight, base oil and 7-8.5 parts of additives, wherein the total weight is 100 parts; the additives comprise a dispersing agent, a viscosity modifier, an anti-wear agent, an anti-friction agent and an antirust agent, the dispersing agent is polyisobutene succinimide or boronized polydiisobutyleneimine, the viscosity modifier is polymethacrylate PMA, the anti-wear agent is one or more of modified nano magnesium silicate and modified nano lanthanum borate, the antirust agent is optional one of pentaerythritol monooleate,T746 and T747, and the anti-friction agent is oil-soluble organic molybdenum. The lubricating oil has the advantages that lubricating oil performance improvement by the coordination of the various modification components is much better than the superposition of the influence of the independent use of each modification component on base oil performance, and the wear resistance, friction resistanceand dispersity of lubricating oil can be improved evidently.

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. Modified organic molybdenum is often added to engine oil as a friction reducing agent, such as commonly used molybdenum dialkyldithiophosphate, molybdenum dialkyldithiocarbamate, molybdenum diisopropyldithiophosphate sulfide, di( 2-Ethylhexyl) molybdenum dithiophosphate oxysulfide; but these organic molybdenum modifiers used on the market all contain sulfur and phosphorus elements, which will produce harmful substances and corrode metals during use. Therefore it is necessary to provide a better solution. Contents of the invention [0003] The object of the present invention is to provide a lubricating oil, which can effectively solve the above ...
