Embodiment 1

[0049]8.828kg of base oil, 0.65kg of compounding agent, 0.1kg of dialkyldithiosulfide molybdenum thiophosphate, 0.33kg of 60%-100% acrylate polymer solution, 0.08kg of 30%-50% concentration The acrylate polymer solution and 4mL1# composite anti-foaming agent were sequentially added to the stirring container and stirred for 45 minutes. The sample was observed and it was completely transparent, which is a long-life manual transmission oil composition. The oil change mileage is 50Wkm.

Embodiment 2

[0051]8.46kg of base oil, 0.95kg of compounding agent, 0.1kg of dialkyldithiosulfide molybdenum thiophosphate, 0.4kg of 60%-100% acrylate polymer solution, 0.06kg of 30%-50% The acrylate polymer solution and 4mL1# composite anti-foaming agent were sequentially added to the stirring container and stirred for 45 minutes. The sample was observed and it was completely transparent, which is a long-life manual transmission oil composition. The oil change mileage is 50Wkm.

Embodiment 3

[0053]8.788kg of base oil, 0.5kg of compounding agent, 0.15kg of dialkyldithiosulfurized molybdenum thiophosphate, 0.45kg of 60%-100% acrylate polymer solution, 0.1kg of 30%-50% The acrylate polymer solution and 4mL1# composite anti-foaming agent were sequentially added to the stirring container and stirred for 45 minutes. The sample was observed and it was completely transparent, which is a long-life manual transmission oil composition. The oil change mileage is 30Wkm.

[0054]Among them, the compound agent contains 50%-60% mineral oil, 10%-20% alkarylamine, 10%-20% phosphate amine salt, and 5%-10% substituted thiadiazole.

Abstract

The invention discloses a long-life manual transmission oil composition, which comprises the following components by weight percentage: 80%-90% of base oil; 5.0%-8.0% of a complexing agent; 0.8%-1.2%of an extreme pressure anti-wear agent; 3.0%-5.0% of a viscosity index improver; 0.6%-1.0% of a pour point depressant; and 0.03%-0.05% of an anti-foaming agent. According to the long-life manual transmission oil composition, the oil change mileage is as long as 50Wkm and is prolonged by 10 times compared with the most common oil change period 5-6Wkm of existing transmission oil. The long-life manual transmission oil composition provided by the invention has good detergency and dispersibility, oxidation and corrosion resistance, thermal stability, bearing resistance, elastomer compatibility andhigh-level shear stability, overall performance is improved, the service life of a vehicle gear transmission system can be effectively prolonged, and the oil change period of the vehicle gear transmission system can be effectively prolonged.

Description

Technical field[0001]The invention belongs to the technical field of lubricating oil, and specifically relates to a long-life manual gearbox oil composition.Background technique[0002]The manual transmission (box) is a transmission device used to change the speed and torque transmitted from the engine to the driving wheels. Under various working conditions such as starting on the spot, climbing, turning, and accelerating, the car can obtain different traction and Speed, while enabling the engine to work in a more favorable range of operating conditions.[0003]Manual transmission oil is generally called gear oil. It is an oil product that keeps the transmission system clean. It has the function of lubricating and extending the life of the transmission. It has resistance to low temperatures. It can also carry out and effective lubrication at low temperatures. Guarantee gearbox performance under severe operating conditions.[0004]In order to meet the ever-increasing requirements for durab...
