Problems solved by technology

[0006] The above prior art only discloses a single hydraulic oil or transmission oil, which does not have the dual functions of hydraulic oil and transmission oil, and focuses on improving the low-temperature performance or anti-wear performance of the oil, ignoring the high-temperature oxidation resistance of the oil performance, but in practical applications, the internal temperature of mechanical equipment will rise rapidly after high-speed operation, and the oil will easily become darker and thicker, which will affect the fluidity and then affect the mechanical work

Abstract

The invention provides hydraulic transmission dual-purpose oil and a preparing method thereof, and belongs to the technical field of lubricating oil processing. The hydraulic transmission dual-purposeoil is prepared from, by mass, 96-99 parts of base oil, 0.6-4 parts of antioxidant and 0.5-1.5 parts of extreme-pressure anti-wear additive, wherein the antioxidant is a mixture of an oxidation and corrosion inhibitor and an antioxygen and anti-gum agent. The hydraulic transmission dual-purpose oil has excellent high-temperature oxidation-resistant performance, a high viscosity index, a wide using temperature range and good demulsibility, rust resistance, hydrolytic stability and thermostability, and through the hydraulic transmission dual-purpose oil, mechanical equipment can work normally on the serious work condition.

Description

technical field [0001] The invention relates to the technical field of lubricating oil processing, in particular to a dual-purpose oil for hydraulic transmission and a preparation method thereof. Background technique [0002] Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays the roles of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc. in the hydraulic system. For hydraulic oil, it should first meet the requirements of the hydraulic device on the liquid viscosity at the working temperature and the starting temperature. Since the viscosity change of the lubricating oil is directly related to the hydraulic action, transmission efficiency and transmission accuracy, the viscosity-temperature performance of the oil is also required. And shear stability should meet the various demands put forward by different uses. Transmission oil is the medium used in the transmission system ...
