Abstract

The invention is suitable for the technical field of lubricating oil, and provides lubricating oil and a preparation method thereof. The lubricating oil is prepared from the following raw materials in percentage by weight: 18-25% of polyol ester, 8-10% of alkyl naphthalene, 26.3-40.75% of an additive, and the balance of poly alpha olefin. The lubricating oil disclosed by the invention is more stable in wear resistance, and the wear resistance of the lubricating oil disclosed by the invention exceeds 15% of the ACEA E6 standard requirement; the lubricating oil provided by the invention can better reduce the formation of sediments, and can provide excellent engine cleaning performance which exceeds 36% of the API CI-4 standard requirement; the viscosity stability is high, and the viscosity stability performance exceeds 8 times of the APICI-4 standard requirement; the raw materials of the lubricating oil do not contain corrosive substances, the lubricating oil does not harm the environment or damage mechanical equipment, and the lubricating oil is non-flammable and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to a lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is a technology-intensive product, which is a mixture of complex hydrocarbons, and its real performance is the combined effect of complex physical or chemical changes. Lubricating oil has the functions of reducing friction, avoiding heat, preventing machine wear and medical purposes. [0003] At present, ordinary lubricating oils on the market are not outstanding in terms of anti-wear ability, viscosity stability and cleaning performance, but those with better effects are generally added with fluoride, which has certain pollution to the environment. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a lubricating oil and a preparation method thereof, aiming at solving the problems existing in the prior art pointed out i...
