Benefits of technology

This patented product with excellent performance for use on vehicles can protect from wear caused by high pressures or temperature changes without losing its effectiveness over time due to degrading components like oxygenated compounds that are commonly found at temperatures below 0°C (even lower). Its main technical effects include improved durability against wearing compared to existing fluids used during operation, reduced friction when transmitting torque through an automobile' s drive system, increased efficiency under varying conditions such as weather, rainwater, snow, etc., prevention of rust formation even after prolonged exposure to harsh environments while maintaining their ability to transmit signals effectively across different types of media.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the durableness and heat resistant qualities of vehicular transmission systems through various improvements made during production or usage over time. Specifically, there may be issues related to maintaining proper lubrications while reducing wear and tearing caused by abrasive materials present at certain parts inside these transmission fluids. Additionally, the current methods mentioned above can cause damage when changing gears under severe weather situations. Therefore, researches aimed towards developing better lubricants without compromising their effectiveness against wears and environmental concerns.

Embodiment 1

[0024] Raw materials (mass percentage) of long-life anti-wear transmission oil: Lubrizol LUBRIZOL CVT10 additive 21.4%, Vanderbilt VANLUBE 996E antioxidant 0.7%, Ssangyong III type 3cst / 70N base oil 45.2%, Ssangyong III type 4cst / 100N base oil 20%, the balance is INEOS PAO4 polyalphaolefin base oil.

[0025] The preparation method of the long-life anti-wear transmission oil: put each raw material into a blending kettle, raise the temperature to 85°C, stir at a speed of 300r / min for 40-80min, and cool to a room temperature of 20°C to obtain the finished product. The present invention adds INEOS PAO 4 and Vanderbilt VANLUBE 996E, so that the service life is increased by 50% compared with the original one, and the anti-wear performance is enhanced at the same time.

Embodiment 2

[0027] Raw materials (mass percentage) of long-life anti-wear transmission oil: 21.4% of viscosity index improver, 0.7% of antioxidant, 1.5% of coupling agent, 45.2% of 70N base oil, 20% of 100N base oil, and the balance is polyα Olefinic base oils.

[0028] The 70N base oil is Korean Ssangyong Group III 3cst / 70N base oil. Its physical and chemical indicators are as follows: kinematic viscosity (40°C) 9.2mm 2 / s, viscosity (100°C) 2.6mm 2 / s, flash point (opening) 190°C, pour point -39°C.

[0029] The 100N base oil is Korean SsangYong III type 4cst / 100N base oil. Its physical and chemical indicators are as follows: kinematic viscosity (40°C) 18.0mm 2 / s, viscosity (100°C) 4.1mm 2 / s, flash point (opening) 221°C, pour point -36°C.

[0030] The viscosity index improver is a hydrogenated polyisoprene-b-polybutadiene-b-polystyrene triblock copolymer (prepared by the method shown in Example 1 of the Chinese patent whose application number is 201310343710.X ).
