Hydraulic oil and production method thereof

Abstract

The invention discloses a hydraulic oil, which is composed of the following raw materials in percentage by weight: 85 to 95% of 22# steam turbine oil, 0.05 to 1.0% of T-501, 0.015 to 1.0% of T746, 0.5 to 8.0% of T202, 0.5 to 10% of lanolin magnesium soap, 0.5 to 4.0% of antifoaming agent, 0.5 to 4.0% of viscosity adjuster, and 0.01 to 2.0% of high-molecular polyester. The production method comprises the following steps: adding 22# steam turbine oil into a container, heating to a temperature of 120 DEG C, dehydrating in vacuum for 15 minutes under stirring, adding lanolin magnesium soap, high-molecular polyester, T-501, T-746, T-202, and an antifoaming agent into the container, after the components are completely dissolved, adding a viscosity adjuster, stirring to completely dissolve the viscosity adjuster, stopping vacuumizing and heating, cooling to a temperature of 50 DEG C or less, sampling, detecting, cooling to a room temperature, and packaging.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a low-cost hydraulic oil with lubricating, extreme pressure, anti-rust, anti-corrosion, heat conduction and other functions and its production method. Background technique [0002] In the manufacturing equipment industry, oil used for hydraulic lifting, hydraulic pressure transmission, hydraulic support, etc. is a commonly used petrochemical product. Some existing hydraulic oils often suffer from swelling and leakage of sealing rings in hydraulic systems and poor rust resistance. The problem needs to be solved urgently. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and provide a low-cost hydraulic oil with functions such as lubrication, extreme pressure, rust prevention, corrosion resistance and heat conduction, and a production method. [0004] The technical solution o...
