Nano-diamond-ene containing high-wear-resistant engine lubricating oil and preparation method therefor

Abstract

The invention discloses nano-diamond-ene containing high-wear-resistant engine lubricating oil and a preparation method therefor. The engine lubricating oil is characterized by being prepared from the following raw materials in parts by weight: 1-2 parts of nano diamond ene, 50-70 parts of rapeseed oil, 1-2 parts of titanate coupling agent, 15-25 parts of poly alpha olefin PAO6, 5-15 parts of polyol ester PriEco3000, 1-3 parts of polyacrylate, 4-8 parts of sulfur powder, 0.5-1 part of tungsten powder, 5-10 parts of zeolite ZIF-8, 2-3 parts of linoleic acid, 15-20 parts of dimethyl sulfoxide, 5-10 parts of pour point depressant LZL803B, 4-7 parts of ethylene-propylene copolymer T618, 15-20 parts of deionized water and a proper volume of anhydrous ethanol. According to the engine lubricating oil and the preparation method therefor, the hydrophobic and lipophilic material, i.e., the zeolite ZIF-8 is introduced and is matched with the added nano diamond ene, so that the coefficient of friction of the lubricating oil is lowered, the degree of wear is reduced, and the service lives of machinery are prolonged.

Description

technical field [0001] The invention relates to an engine lubricating oil and its preparation, in particular to a highly wear-resistant engine lubricating oil containing nano-diamondene and a preparation method thereof. Background technique [0002] Lubricants are also widely used in aviation, automobile, machining, transportation, metallurgy, coal, construction, light industry and other industries. With the rapid development of industry, the demand for lubricating oil is increasing year by year. The traditional mineral oil-based lubricants not only pollute the environment, but also aggravate energy depletion. While it is used in large quantities, it will inevitably flow into the environment through various channels such as transportation, leakage, splashing, overflow or improper discharge, seriously polluting soil and water resources, and destroying the ecological environment and ecological balance. Green lubricating oil is also called environmentally friendly or environm...
