[0060] The present invention has no special limitation on the preparation method of the hydraulic oil, which can be prepared by mixing the components of the hydraulic oil described in the above technical solution. In an embodiment of the present invention, the preparation method of the hydraulic oil may be:
[0061] mixing polyalphaolefin, diester compound, viscosity modifier, antioxidant, antirust agent, extreme pressure antiwear agent and coloring agent to obtain a mixture;
[0062] The mixture is mixed with an antifoaming agent to obtain a hydraulic oil.
[0063] In the present invention, the types, sources and parts by weight of the polyalphaolefins, diester compounds, viscosity modifiers, antioxidants, rust inhibitors, extreme pressure antiwear agents, dyeing agents and antifoaming agents are the same as The types, sources and parts by weight of the polyalphaolefins, diester compounds, viscosity modifiers, antioxidants, rust inhibitors, extreme pressure and antiwear agen...
Embodiment 1
[0077] 89g of PAO2, 11g of dioctyl sebacate, 15g of VX7510, 0.4g of 2,6-di-tert-butyl-p-cresol, 0.4g of N-phenyl-1-naphthylamine, 2.0g of TCP Stir and mix with 0.005g of oily red at 80°C for 0.5 hours to obtain a mixture; filter the mixture with diatomaceous earth, mix and stir the filtered mixture and methyl silicone oil evenly to obtain hydraulic oil, and the methyl silicone oil The mass content in the hydraulic oil is 25 μg / g.
[0078]According to the method described in the above technical solution, the kinematic viscosity, low temperature stability, pour point, flash point, ignition point, evaporation loss, wear performance, and oxidation corrosion of the hydraulic oil prepared in Example 1 of the present invention were tested.
