Embodiment 1
[0035] Energy-saving construction machinery hydraulic oil raw materials (parts by weight): 0.6 parts of tricresyl phosphate, 1.0 parts of antiwear agent, 5 parts of benzotriazole octadecylamine salt, 3 parts of ethylene glycol oleate, hydrogenated styrene isoprene 80 parts of copolymer, 2 parts of monoalkenyl succinimide, 2 parts of 2,5-di-tert-butyl hydroquinone, 3 parts of 4,4'-dioctyl diphenylamine, 6 parts of polymethacrylate parts, 0.03 parts of simethicone oil, and 900 parts of base oil.
[0036] The base oil is obtained by uniformly stirring and mixing dinonyl sebacate, diisopropyl sebacate, and pentaerythritol tetramyristate in a mass ratio of 1:1:1.
[0037] The anti-wear agent is composed of 50wt% N, N-di(2-ethylhexyl) molybdenum dithiocarbamate and 50wt% N, N-bis(tridecyl) molybdenum dithiocarbamate, and stir and mix uniformly get.
[0038] Preparation of energy-saving engineering machinery hydraulic oil: add base oil to the blending kettle, heat up to 75°C, add p...
Embodiment 2
[0040] It is basically the same as Example 1, except that the base oil is uniformly obtained by stirring and mixing diisopropyl sebacate and pentaerythritol tetramyristate at a mass ratio of 1:1. Obtain the energy-saving engineering machinery hydraulic oil of embodiment 2.
Embodiment 3
[0042] It is basically the same as Example 1, except that the base oil is obtained by stirring and mixing dinonyl sebacate and pentaerythritol tetramyristate at a mass ratio of 1:1. Obtain the energy-saving engineering machinery hydraulic oil of embodiment 3.
