Embodiment 1

[0031] The long-life hydraulic oil of this embodiment, wherein the raw material components are in parts by weight: 83 parts of hydrogenated base oil of type II, 0.1 part of defoamer, 0.1 part of pour point depressant, 0.1 part of demulsifier, and viscosity index improver 1 part, 0.1 part of liquid mixed shielding phenol, 0.1 part of dialkyl dithiophosphoric acid derivative, 0.1 part of copper corrosion inhibitor, 0.01 part of phosphate ester, 0.01 part of synthetic petroleum calcium sulfonate, and 1 part of detergent LZ6786. The preparation process is as follows: mix the above components according to the above ratio, then add them into the blending tank and stir the mixed solution evenly, then control the temperature of the blending tank at 55°C and stir the mixed solution for 2 hours at the same time to obtain the described long-life hydraulic oil.

Embodiment 2

[0033] The long-life hydraulic oil of this embodiment, wherein the raw material components are: 90 parts of hydrogenated base oil of type II, 0.8 part of defoamer, 0.8 part of pour point depressant, 0.8 part of demulsifier, and viscosity index improver in parts by weight. 3 parts, 0.5 parts of liquid mixed shielding phenol, 0.5 parts of dialkyl dithiophosphoric acid derivatives, 0.5 parts of copper corrosion inhibitor, 0.05 parts of phosphate ester, 0.05 parts of synthetic petroleum calcium sulfonate, and 2 parts of detergent LZ6786. The preparation process is as follows: mix the above components according to the above ratio, then add them into the blending tank and stir the mixed solution evenly, then control the temperature of the blending tank at 55°C and stir the mixed solution for 2 hours at the same time to obtain the described long-life hydraulic oil.

Abstract

The invention discloses clean type long-service-lifetime hydraulic oil. The hydraulic oil comprises the following raw materials in parts by weight: 83-97 parts of class II hydrogenated base oil, 0.1-1.5 parts of a defoaming agent, 0.1 to 1.5 parts of a pour point depressant, 0.1 to 1.5 parts of a demulsifier, 1 to 6 parts of a viscosity index improver, 0.1 to 1 part of liquid mixed type hindered phenol, 0.1 to 1 part of a dialkyl dithiophosphoric acid derivative, 0.1 to 1 part of a copper corrosion inhibitor, 0.01 to 0.1 part of phosphate, 0.01 to 0.1 part of synthetic calcium petroleum sulfonate and 1 to 3 parts of a clearing agent LZ6786. The invention aims to solve the problems of short service lifetime of hydraulic oil, increased cost caused by frequent replacement of the hydraulic oiland the like due to the fact that the existing hydraulic system works under higher pressure.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a clean long-life hydraulic oil. Background technique [0002] With the development of industrial technology, more and more automation equipment is used, and hydraulic systems are widely used, such as excavators and forklifts. At present, the hydraulic system starts to use high-performance pumps to provide higher pressure and system efficiency, which causes the pressure of the hydraulic system to increase sharply. Traditional hydraulic oil cannot provide sufficient lubrication protection for hydraulic system components in ultra-high pressure hydraulic systems. As a result, the plunger of the hydraulic pump and the inner cavity of the plunger cylinder will be worn, and the temperature of the hydraulic system will also rise sharply, which will accelerate the oxidation of the hydraulic oil and reduce the service life. The TOST oxidation life of the traditional hydraulic oil on the ma...
