Abstract

The invention relates to a lubricating oil for vehicles, which is prepared from the following components in parts by weight: 92-100 parts of base oil, 6-8 parts of ricinoleic acid, 3-4 parts of ethylenediamine oleate, 2-3 parts of vinyl ethyl ether, 3-4 parts of sodium lauroyl sarcosine, 1.5-2 parts of perfluorooctyl ethylene, 12-15 parts of 2-ethyl decanol, 2-3 parts of ethylene bis oleamide, 4-5 parts of sodium ethylenediamine diorthophenylacetate and 1.2-1.8 parts of nano bismuth oxide. The lubricating oil for vehicles is prepared from the nano active components and multiple additives by a special technique; the components have outstanding synergistic effects; and the lubricating oil for vehicles has favorable antiwear anti-friction synergistic performance, effectively prolongs the oxidation induction time of the oil product, effectively inhibits the increase of the viscosity of the oil product, and has favorable antioxidation synergistic performance. Besides, the added additives enhance the corrosion inhibition property.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a vehicle lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is generally the product of fractionated petroleum, and it is also extracted from animal and vegetable oils, including "lubricating grease". Generally, it is a non-volatile oily lubricant. It is a liquid lubricant used in various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. [0003] Lubricating oil is divided into three categories according to its source: moving oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. The amount of petroleum lubricating oil accounts for more than 97% of the total amount, so lubricating oil often refers to petroleum lubricating oil. It is mainly used to reduce the friction betwe...
