Abstract

The invention relates to a low-viscosity manual transmission oil composition with extreme pressure and anti-wear behaviors. The composition comprises, by weight, 100 parts of manual transmission oil with a viscosity grade of 75 W/80 or 75 W/85 and 2 to 5 parts of sulfurized olefin. The manual transmission oil composition provided by the invention has excellent performance and a wide application scope, can greatly improve the extreme pressure and anti-wear behaviors of low-viscosity manual transmission oil for passenger cars, meets the special requirement of clients for the extreme pressure and anti-wear behaviors of low-viscosity manual transmission oil, and is good in stability and low in metal corrosivity. Moreover, the manual transmission oil composition provided by the invention is simple in composition, uses easily available raw materials, is easy to prepare and has good large-scale application prospects.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a manual gearbox oil composition with low viscosity and strong extreme pressure and anti-wear performance. Background technique [0002] Passenger car manual transmission fluid (hereinafter referred to as MTF) is a kind of lubricating oil suitable for manual transmission system, which mainly plays the role of lubricating, cooling, protecting equipment and transmitting power. At present, domestic lubricating oil companies have developed mature products of manual transmission oil, and the performance of the oil products meets the performance requirements of manual transmissions. However, in practical applications, some OEM specifications stipulate that manual transmission fluids must meet the requirements of low viscosity and special extreme pressure performance tests at the same time. The specific requirements are shown in Table 1. [0003] Table 1 Partial index requirements of som...
