[0026] Experimental Example 1 Performance Test

[0027] For the quality technical index of the shock absorber oil product, now take the enterprise standard of shock absorber oil developed by the company as the benchmark, and compare with the reference oil according to the conventional known test method with the examples 1-5, wherein, the reference oil is Refers to: The reference oil is a SAF type product, which is widely used in modern automobile shock absorbers. The performance comparison results of the products are shown in Table 3:

[0028] Table 2 Embodiment 1~5 performance data

[0029]

[0030] From the data of Examples 1 to 5, it can be seen that the performance of Example 2 is the best in the No. 22 kinematic viscosity grade. The degradation rate is more than 70%, but the existing shock absorber oil does not have biodegradability, which is obviously inferior to the present invention.

Abstract

The invention provides a biodegradable environment-friendly combination of shock absorber oil. The biodegradable environment-friendly combination of the shock absorber oil comprises, by weight, 0.1%-22% of a viscosity index improving agent, 0.01-4.5% of an extreme-pressure anti-wear agent, 0.01-4.0% of an antirust agent, 0.05-1.5% of a pour point depressant, 0.01-4.0% of an antioxidant, 0.0001-0.015% of a composite anti-foaming agent and the balance biodegradable base oil. The biodegradable environment-friendly combination of the shock absorber oil has the most outstanding advantages of being biodegradable and environmentally friendly and excellent characteristics of excellent abrasion resistance and shock absorption, high viscosity index, lower pour point and the like. The biodegradable environment-friendly combination of the shock absorber oil is suitable for the fields of automobiles, motorcycles, rail transit and the like.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a composition of biodegradable environment-friendly shock absorber oil, especially a composition with biodegradable synthetic oil as base oil and biodegradable additives as important components . Background technique [0002] There are many shock absorber manufacturers in my country, and the production process and structure of the products are also quite different. Therefore, the requirements for the shock absorber oil, which is an important component of the shock absorber, are also different. At present, there is no unified quality standard requirement. However, according to the performance characteristics of the shock absorber and its role in the driving process of the vehicle, it mainly involves suitable viscosity, shear resistance and foam resistance to provide effective and stable damping force, and good viscosity-temperature performance. In order to adapt to the temperature diffe...
