Problems solved by technology

[0002] Hydraulic oil is a hydraulic medium used in a hydraulic system that uses liquid pressure energy. It plays the role of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust and cooling in the hydraulic system. Among them, the gas spring anti-friction hydraulic oil is the hydraulic oil. One of them, mainly to achieve the purpose of stable release, storage release, and lubrication of industrial gas springs, but the existing gas spring anti-friction hydraulic oil has poor viscosity-temperature performance and low-temperature flow performance, resulting in long-term working process In this process, the buffering and recovery performance of the entire hydraulic system will be affected, thereby affecting the work of the entire hydraulic system

Abstract

The invention relates to the technical field of lubricating oil, in particular to a gas spring anti-attrition hydraulic oil composition which is composed of mineral base oil, a lubricating additive, an anti-rust additive, a pour point depressing additive, an antioxidant additive, a defoaming additive, a tackifier and an auxiliary agent. According to the invention, based on the alkane solvent base oil, the lubricating additive, the antirust additive, the pour point depressing additive and the antioxidant additive are sequentially mixed, so that the excellent wear resistance, oxidation stability and corrosion and rust resistance of the hydraulic oil composition can be ensured; the viscosity index of the hydraulic oil composition can be greatly improved, so that the whole composition is more suitable for low-temperature starting, the hydraulic oil composition is further ensured to have excellent viscosity-temperature performance and low-temperature fluidity, and the hydraulic and supporting systems are sequentially ensured to have good cold starting, pumping, buffering and restoring performance in a low-temperature environment.
