Abstract
The invention discloses anti-oxidation automobile lubricating oil. The anti-oxidation automobile lubricating oil is composed of, by weight, 30-50 parts of modified nano-diamonds, 50-70 parts of base oil, 20-30 parts of an organic molybdenum mixture, 10-20 parts of an antioxidant and 15-30 parts of a friction improver. The invention further discloses a preparation method for the anti-oxidation automobile lubricating oil. The antioxidant is applied to the automobile lubricating oil so that oxygenolysis of effective constituents in the lubricating oil can be restrained and oil viscosity indexes can also be improved. Meanwhile, the friction improver is also added, so that friction performance is improved, and the service life of an automobile is prolonged.
Description
Technical field
The present invention relates to automobile oil technical field, particularly a kind of anti-oxidant automobile oil and preparation method thereof.
Background technology
The current performance that has many solid lubricants is fine, but because density can not be suspended in oil greatly, coarse size enters not go friction pair, and agglomerate deposition is serious, has used obstruction oil circuit of a specified duration, cannot in lubricating oil, apply.Extreme pressure anti-wear additives in conventional lubrication oil is a little sulphur, phosphorus, muriate often, by boundary lubrication TRANSIENT HIGH TEMPERATURE high pressure and friction pair, generates metallic compound, improves hardness and resistance to abrasion.Though but this compound is hard very crisp, at friction process, constantly come off and constantly form, both corroded parts, consumed again additive, machinery or the work-ing life of lubricating oil are all very short.Wear-resistant composition in conventional lubrication oil is as zinc dialkyl dithiophosphate (T202 oxidation and corrosion inhibitor) etc., and sulfur-bearing, phosphorus, zinc, not only corrode silver-colored bearing, poisons waste gas transfer equipment catalyzer, goes back pollutant atmosphere.Lube product will be used conventionally under very low envrionment temperature, particularly in the winter time and under cold car state, therefore require the lubricating oil using to there is good low temperature flowability, be so not only conducive to the normal startup operation of machine, can also reduce the wearing and tearing of machine in start-up course.
