Abstract

The invention belongs to the field of engine lubricating oil and discloses synthetic supercharged methanol engine oil as well as a preparation method and an application thereof. 95-97 parts of synthetic base oil is added to a three-mouth flask provided with a stirring device and a water bath device and subjected to a water bath at the constant temperature of 60 DEG C, then 0.5-1 part of an amine antioxidant, 1-1.5 parts of an extreme-pressure anti-wear agent, 0.2-0.5 parts of a metal passivator, 0.3-0.5 parts of a metal detergent, 0.1-0.5 parts of an ashless dispersant and 0.1-0.2 parts of an anti-foaming agent are added and stirred, and the synthetic supercharged methanol engine oil is obtained. The synthetic supercharged methanol engine oil has the advantages that the viscosity index is high, the shear performance is good, the low-temperature performance is good, the base number is large, the lubricity, the anti-oxidation and anti-corrosion performance and the cleaning and dispersing effect are good, a preparation process is simple, the cost is low, application range is wide, and the like.

Description

Technical field [0001] The invention belongs to the field of engine lubricating oil, and discloses a synthetic supercharged methanol engine oil and a preparation method and application thereof. Background technique [0002] At present, with economic development and technological progress, methanol as a new type of green fuel is increasingly being applied to engines. However, as an alternative energy source, methanol still has many problems in actual use: [0003] (1) Methanol will produce formaldehyde and formic acid during the combustion process, which will reduce the use effect of lubricating oil and corrode the synthetic supercharged engine; [0004] (2) It is inevitable that a small amount of methanol will enter the lubricating oil during the work of a synthetic supercharged engine, thereby diluting the lubricating oil; [0005] (3) Methanol has strong water absorption, which will cause the wear and tear of the synthetic supercharged engine and cause the engine to malfunction. S...
