[0043] Add GTL-4 base oil and PAO-4 into the kettle, raise the temperature to 50°C, and stir for 0.5h; add high-viscosity polyester and polymethacrylate into the kettle, and stir for 0.5h; add the additive package into the kettle, and heat up To 65 ° C, fully mixed by stirring and static mixer, time 1.5h; the above process is carried out under the protection of 0.1MPa nitrogen, l...

Embodiment 5

[0045] Preparation of compound additives for transmission oil: Add 3 parts by weight of calcium alkylbenzenesulfonate and 1 part by weight of sulfurized calcium alkylphenate to 60 parts by weight of alkyldibenzyltoluene and stir at 400 rpm for 10 minutes, then add 6 parts by weight Borated polyisobutylene succinimide was stirred at a speed of 400 rpm for 20 minutes to obtain a composite additive for transmission oil.

[0046] Long-life, low-temperature and energy-saving manual transmission oil raw materials (mass percentage): 6% of transmission oil compound additives, 35% of 13-docosanoic acid-13-docosyl ester, and 0.6% of polymethacrylate , polyalphaolefin 15%, di-n-octyl adipate 10%, organic molybdenum 0.08%, and the balance is GTL-4 base oil.

[0047] The organic molybdenum is obtained by uniformly stirring and mixing 50 wt % diethylhexyl molybdenum dithiophosphate and 50 wt % diisooctyl molybdenum dithiophosphate.

Abstract

The invention discloses long-life, low-temperature and energy-saving manual transmission oil, which is prepared from the following raw materials in percentage by weight: 4 to 8 percent of transmission oil composite additive, 30 to 60 percent of polyester, 0.5 to 1.0 percent of polymethacrylate, 10 to 40 percent of poly-alpha-olefine, 5 to 20 percent of diester, 0.02 to 0.15 percent of organic molybdenum, and the rest of natural gas synthetic oil. The manual transmission oil has excellent low-temperature fluidity and relatively high transmission efficiency, can effectively reduce power consumed inovercoming resistance, and is energy-saving; the manual transmission oil can improve oil film thickness, absorb impact load, reduce gear noise, prevent oil shortage during start-up, eliminate the phenomenon of stick-slip and the phenomenon of temperature rising caused by friction heat, inhibit viscosity change generated by oxidation, and is good in damping effect; the polyester has very high oil film strength, can effectively enhance anti-micro-pitting-corrosion property of the transmission oil, prolong an oil change period, and improve the service life.

Description

technical field [0001] The invention relates to a vehicle transmission system and belongs to the technical field of vehicle gear oil, in particular to a long-life, low-temperature and energy-saving manual transmission oil. Background technique [0002] Vehicle gear oil can be divided into manual transmission oil and vehicle drive axle oil according to its different application occasions. The oil for manual transmission should have excellent anti-corrosion performance, thermal oxidation stability, extreme pressure anti-wear performance and sealing adaptability. Due to China's vast territory, there is a huge temperature difference from south to north. With the rapid development of the transportation industry, the flow of logistics across regions, especially how to adapt to the temperature difference in winter is particularly prominent. On the one hand, at low temperature, the gear shifting of the vehicle will become sticky or even fail to shift into gear, which changes the lu...
