Problems solved by technology

For example, Chinese patent CN101993766A discloses a fully synthetic high-viscosity synthetic vehicle shock absorber lubricating oil. The index needs to be further improved (the product viscosity index in the open patent is not more than 300); the synthetic vehicle shock absorber lubricating oil disclosed in Chinese patent CN1343578A and CN101486944A has good low-temperature performance and anti-friction and anti-wear performance, but in viscosity-temperature performance still needs to be improved

Abstract

The invention provides a lubricating oil composition as well as a preparation method and application thereof, and relates to the technical field of lubricating oil. The lubricating oil composition provided by the invention is prepared from the following components in percentage by weight: 65 to 85 percent of poly-alpha-olefin synthetic oil, 3 to 20 percent of synthetic ester, 10 to 15 percent of a polymethacrylate viscosity index improver, 0.05 to 0.2 percent of an antioxidant, 0.05 to 0.15 percent of an anti-wear reagent at extreme pressure, 0.05 to 0.1 percent of a friction reducing agent, 0.01 to 0.05 percent of an anti-rust agent and 0.001 to 0.02 percent of an anti-foaming agent. The lubricating oil composition provided by the invention has outstanding viscosity-temperature performance, excellent oxidation resistance and low-temperature performance, good anti-rust performance, extreme pressure anti-wear performance and anti-foaming performance, has good adaptability to rubber, and can meet all-weather and long-life use requirements in different regions.

Description

technical field [0001] The present invention relates to the technical field of lubricating oil, in particular to a lubricating oil composition and a preparation method and application thereof. Background technique [0002] The shock absorber is a key component of the vehicle, shouldering many important functions of the vehicle, such as elastic support for the body and the load mass, thus determining the bearing capacity of the vehicle; it can attenuate the vibration caused by the uneven road surface to the body and passengers. (attenuate the amplitude, etc.), reduce the inertial force on the body; ensure that the wheels are on the ground at any time, improve the steering and braking function of the vehicle, and ensure the smoothness and comfort of the vehicle; improve the grounding of the vehicle and avoid the body and axles. wheel collision, thereby improving safety; reducing sudden strong impact during vehicle driving, protecting vehicle components, instruments and passeng...
