Description
Technical Field
The invention relates to the technical field of shock absorber oil, and particularly relates to a shock absorber oil composition and a preparation method thereof.
Background
The shock absorber is hydraulic oil. The shock absorber oil had the following properties: 1. has the main performance of antiwear hydraulic oil. The working principle of the shock absorber oil in the shock absorber is similar to that of anti-wear hydraulic oil, so that the shock absorber oil also has the requirements of rust prevention, wear resistance, oxidation resistance, foam resistance, compatibility to sealing elements and the like. 2. High antioxidizing performance. When the road condition is poor, the action of the shock absorber oil is strong, at the moment, the running speed is slow, the windward flow speed is low, the temperature of the shock absorber oil can rise to more than 150 ℃, the temperature of the shock absorber oil rises and falls, and the oxidation is severe. In actual operation, the oil is usually replaced when the shock absorber is damaged and needs to be disassembled, and the shock absorber is rarely disassembled specially for oil replacement, so that the oil is required to have a longer service life. 3. The low-temperature fluidity is good. Due to the large geographical mobility of vehicles, the vehicles are frequently placed outdoors, and the pour point of the shock absorber oil is required to be lower than-40 ℃ in consideration of the cold weather in the winter in the north. 4. Excellent viscosity-temperature performance, which is an important working performance of the shock absorber oil, because the shock absorber oil is continuously heated and cooled, the viscosity is also increased and reduced, if the viscosity change is too large, the resistance of the oil passing through the small holes is also suddenly high and suddenly low, so that the shock absorption is very unstable, namely the shock absorption attenuation is large. Thus, the damper oil is required to have good viscosity-temperature properties.
However, the wear resistance, oxidation resistance, low-temperature fluidity and viscosity-temperature performance of the existing shock absorber oil are only suitable for automobiles with common performance, the existing shock absorber oil cannot meet the conditions required by high-performance automobiles, the existing shock absorber oil has common use effect, and the service life of a shock absorber is seriously shortened.
