[0004] Ester oil has high service temperature, low pour point, good low-temperature fluidity, good viscosity-temperature performance, miscible with mineral oil, low volatility, non-toxic and degradable, and medium price; the disadvantage is poor water stability and medium anti-corrosion performance
When polyalphaolefin is added with oxidation inhibitor, it has high stability, good viscosity-temperature performance, good hydrolytic stability and corrosion resistance, but it is difficult to biodegrade
Polyether also has excellent performance, especially for high temperature, but the compatibility with other oils or additives is general

Abstract
The invention relates to an anti-wear hydraulic oil and a preparation method thereof. The anti-wear hydraulic oil comprises, by mass, 80-85% of base oil, 15-20% of pentaerythritol tetraisocaprylate, and 0.5-1.0% of a composite additive. The preparation method comprises the following steps: respectively adding three base oils and pentaerythritol tetraisocaprylate into a blending kettle, adding the composite additive, carrying out stirring at a controlled temperature in the blending kettle of 50-60 DEG C for 1-2 h, and controlling the viscosity in the blending process to be 65-72 mm<2> / s in order to obtain the anti-wear hydraulic oil. The semi-synthetic anti-wear hydraulic oil integrates the advantages of mineral oil and ester synthetic oil, can meet use requirements of mechanical hydraulic devices under general conditions, also can meet normal working requirements of large mechanical devices under extreme conditions (for example, -30 to 80 DEG C), can be widely used in various large-scale mechanical hydraulic systems, ensures the normal running of devices, effectively prolongs the service life of machines, devices or components, and solves the problems of friction induced wearing, lubricating maintenance or maintenance oil change.
Description
technical field [0001] The invention relates to the field of lubricating oil processing, in particular to an anti-wear hydraulic oil and a preparation method thereof. Background technique [0002] Anti-wear hydraulic oil is developed on the basis of anti-oxidation and anti-rust hydraulic oil. Compared with ordinary anti-oxidation and anti-rust hydraulic oil, its preparation technology is more complicated. When used in medium and high pressure systems, anti-wear hydraulic oil not only has good anti-oxidation and anti-rust properties, but also has outstanding anti-wear properties. When carrying out construction operations in plateau areas, severe cold areas, bridge and tunnel construction, and hot environments, the hydraulic oil used in the hydraulic system of these industrial equipment must fully meet the relevant requirements, which can not only meet the normal operation of the equipment, reduce wear, but also reduce environmental impact. The pollution is the development tr...
