Embodiment 1
[0007] A formulation of biodegradable hydraulic oil. The raw materials in the formulation are composed by weight percentage: 5% phenolic antioxidant, 1% amine antioxidant, 1% P-type non-metallic extreme pressure anti-wear agent, S-P type non-metallic 5% metal extreme pressure antiwear agent, 3% ashless detergent and dispersant, 2% ester rust inhibitor, 1% calcium sulfonate rust inhibitor, 11% organic metal deactivator, 5% ester base oil, Diethanolamide laurate 3%, butyl methacrylate 3%, calcium petroleum sulfonate 1%, succinate sulfonate 5%, diisooctyl dianiline 1%, demulsifier 4%, ethylenediaminetetra At 2% acetic acid, the biodegradable hydraulic oil has outstanding biodegradability, but its oxidation stability is insufficient.
Embodiment 2
[0009] A formulation of biodegradable hydraulic oil. The raw materials in the formulation are composed by weight percentage: 15% phenolic antioxidant, 5% amine antioxidant, 10% P-type non-metallic extreme pressure anti-wear agent, S-P type non-metallic 15% metal extreme pressure antiwear agent, 9% ashless detergent and dispersant, 3% ester rust inhibitor, 5% calcium sulfonate rust inhibitor, 19% organic metal deactivator, 7% ester base oil, Diethanolamide laurate 5%, butyl methacrylate 5%, calcium petroleum sulfonate 5%, succinate sulfonate 10%, diisooctyl dianiline 1.5%, demulsifier 5%, ethylenediaminetetra At 4% acetic acid, the biodegradable hydraulic oil has good oxidation stability, but its biodegradability is insufficient.
Embodiment 3
[0011] A formulation of biodegradable hydraulic oil. The raw materials in the formulation are composed by weight percentage: 10% phenolic antioxidant, 3% amine antioxidant, 6% P-type non-metallic extreme pressure anti-wear agent, S-P type non-metallic 10% metal extreme pressure antiwear agent, 6% ashless detergent and dispersant, 2.3% ester rust inhibitor, 1.5% calcium sulfonate rust inhibitor, 11.9% organic metal deactivator, 5.7% ester base oil, Diethanolamide laurate 3.5%, butyl methacrylate 3.5%, calcium petroleum sulfonate 1.5%, succinate sulfonate 8%, diisooctyl diphenylamine 1.28%, demulsifier 4.5%, ethylenediaminetetra Acetic acid 2.4%, at this time the biodegradable hydraulic oil has outstanding biodegradability and excellent oxidation stability.
