Antistatic highly-abrasion-resisting lubricating oil for environment-friendly and energy-saving engines and preparation method of antistatic highly-abrasion-resisting lubricating oil

Abstract

The invention discloses antistatic highly-abrasion-resisting lubricating oil for environment-friendly and energy-saving engines and a preparation method of the antistatic highly-abrasion-resisting lubricating oil. The antistatic highly-abrasion-resisting lubricating oil is characterized by comprising, by weight, 1-3 parts of quaternary salt cation antistatic agents, 50-70 parts of rap oil, 15-25 parts of poly-alpha-olefin PAO6, 5-15 parts of polyol ester PriEco3000, 1-2 parts of methyl glucoside stearate, 4-8 parts of powdered sulfur, 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 reducers LZL803B, 4-7 parts of ethylene-propylene copolymers T618, 15-20 parts of deionized water and appropriate parts of absolute ethyl alcohol. The antistatic highly-abrasion-resisting lubricating oil has the advantages that a hydrophobic oleophylic material, namely the zeolite ZIF-8, is introduced and can serve as a carrier for tungsten disulfide particles, and integration of the zeolite ZIF-8 and base oil is further improved; the quaternary salt cation antistatic agents are added coordinately, and accordingly, the obtained lubricating oil has excellent antistatic performance.

Description

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