Abstract

The invention relates to lubricating oil and a preparation method thereof. The lubricating oil comprises the following components in parts by weight: 65 to 95 parts of base oil; 1.5 to 3 parts of an antiwear functional agent; 2 to 8 parts of a reinforcing agent; 4 to 15 parts of a viscosity index agent; 0.2 to 1 part of a pour point depressant; 1.5 to 3 parts of an antioxidant and 0.1 to 0.5 partof an anti-foaming agent; the reinforcing agent is formed by mixing the following raw materials in parts by weight: 68 to 75 parts of polymethyl methacrylate; 28 to 35 parts of ester oil; 5 to 10 parts of a diphenylamine antioxidant containing butyl and octyl; 5 to 10 parts of beta-(3,5-di-tert-butyl-4-hydroxy phenyl)propionic acid isooctyl alcohol ester. The lubricating oil prepared through the method has the characteristics of good low-temperature property, appropriate viscosity and good antiwear effect.

Description

technical field [0001] The invention relates to the field of gear lubricating oil compositions, in particular to a lubricating oil and a preparation method thereof. Background technique [0002] Engine lubricating oil plays the role of lubricating, cooling, and reducing friction for the engine. The base oil is the main component of the lubricating oil and provides the main lubricating effect. [0003] In order to adjust the viscosity of engine lubricating oil, components such as viscosity index improver, pour point depressant and friction modifier are usually added to the engine lubricating oil. As shown in the Chinese patent with the application date of May 6, 2011 and the authorized announcement number of CN102766506B, the patent discloses a lubricating oil composition for a full transmission system, the lubricating oil composition includes an ashless dispersant, a friction modifier , phosphorus-containing anti-wear additives, viscosity index improvers, pour point depress...
