Abstract

The invention relates to the technical field of lubricating oil, in particular to hydraulic oil containing a metal nano-additive. The hydraulic oil comprises the following components in percentage by weight: 0.001 to 0.2 percent of the metal nano-additive, 90 to 99 percent of base oil, 0 to 3 percent of a composite multifunctional additive and 0.05 to 0.1 percent of a dispersing agent, wherein the composite multifunctional additive comprises an antioxidant, an anti-wear reagent at extreme pressure, an anti-rust agent, a metal deactivator and synthetic ester compound base oil. According to the hydraulic oil, the conductivity of the hydraulic oil is improved by adding the metal nano-additive, and the risk that the hydraulic oil generates static electricity in the processes of storage, transportation and use can be reduced; and meanwhile, the hydraulic oil can pass through a filter, so abrasion of hydraulic elements cannot be aggravated.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to hydraulic oil containing metal nano-additives. Background technique [0002] When the size of matter reaches the nanometer level, it usually exhibits some special properties. Therefore, since the advent of nanomaterials, nanomaterials have been widely used in different fields. Nano-metal materials still have excellent electrical and thermal conductivity, and composites of nano-metal and rubber materials already have mature product and application experience. [0003] Hydraulic oil is an important medium for hydraulic transmission. In the process of power transmission, the hydraulic oil is constantly flowing, so if the hydraulic oil contains large-sized metal particles, these fine particles will continuously collide with the hydraulic components during use, which will damage the contact parts of the hydraulic oil, including pipelines, Valves and hydraulic pump component...
