Abstract

The invention provides lubricating oil compound and a preparation method thereof. The lubricating oil compound comprises 50-80wt% of poly alpha olefin, 19-39 wt% of ester oil, 0.1-3.0wt% of antioxidant, 0.01-0.5wt% of metal passivator, 0.1-3.0wt% of corrosion inhibitor, 0.5-5.0wt% of extreme pressure antiwear agent and 0.0005-0.05wt% defoaming agent. Compared with existing lubricating oil, the lubricating oil compound has the advantages that the poly alpha olefin in the lubricating oil is good in viscosity-temperature performance, low-temperature flowability and good in thermal oxidation stability; by the ester oil with good oxidation stability and high-temperature performance, high temperature oxidation performance of the lubricating oil compound can be increased; additives with good oxidation stability and extreme pressure antiwear performance are added to form a composite system, and the lubricating oil compound is good in extreme pressure lubricity and high-temperature oxidation stability under interaction of the additives.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to a lubricating oil composition and a preparation method thereof. Background technique [0002] With the improvement of automobile technology, the restriction of energy saving and emission reduction, and people's continuous requirements for car driving performance, the technology level of automobile gearbox is also constantly improving. Dual-clutch automatic transmission (DCT) technology has greatly improved the fuel economy and shifting smoothness of automobiles, so its assembly rate in automobiles continues to rise. Relevant agencies predict that the DCT market demand will reach 10% in 2015. [0003] Foreign DCT technology developed earlier, such as Porsche PDK (Porsche Dual Klutch) technology, Volkswagen DSG (Direct Shift Gearbox) technology, Ford Europe GETRAG-Ford technology, Volvo Power-shift technology, Mitsubishi TC-SST technology are all dual-clutch automatic gear...
