Embodiment 1
[0023] This embodiment provides a dual-purpose oil for hydraulic transmission, including the following raw materials in parts by weight: 97 parts of 250N type III base oil, 1.5 parts of zinc dialkyl dithiophosphate (ZDDP), 1.5 parts of N,N-dithiophosphate 0.5 parts of sec-butyl-p-phenylenediamine (44PD) and 1 part of polyalkyl benzyl sulfide (T324).
[0024] This embodiment also provides a preparation method of the above hydraulic transmission dual-purpose oil: first add 250N type III base oil to the reactor, heat it to 60°C, then add the rest of the raw materials, and pulse the gas until they are evenly mixed.
Embodiment 2
[0026] This embodiment provides a dual-purpose oil for hydraulic transmission, including the following raw materials in parts by weight: 96 parts of 250N type III base oil, 1.5 parts of zinc dialkyl dithiophosphate (ZDDP), 1.5 parts of N,N-dithiophosphate 0.5 parts of sec-butyl-p-phenylenediamine (44PD), 0.08 parts of dodecenylsuccinic acid (T746), 1.5 parts of polyalkyl benzyl sulfide (T324), 0.2 parts of benzotriazole fatty acid ammonium salt (T406), 0.1 part of polymethacrylate (T602HB), 0.0001 part of methyl silicone oil (T901) and 0.05 part of condensate of amine and epoxy compound (T1001). The preparation method is the same as in Example 1.
Embodiment 3
[0028] This embodiment provides a dual-purpose oil for hydraulic transmission, including the following raw materials in parts by weight: 99 parts of 250N type III base oil, 1.3 parts of zinc dialkyl dithiophosphate (ZDDP), 1.3 parts of N,N-dithiophosphate 0.4 part of sec-butyl-p-phenylenediamine (44PD), 0.07 part of dodecenyl succinic acid (T746), 1 part of polyalkyl benzyl sulfide (T324), 0.2 part of benzotriazole fatty acid ammonium salt (T406), 0.3 part of polymethacrylate (T602HB), 0.001 part of methyl silicone oil (T901) and 0.03 part of condensate of amine and epoxy compound (T1001), the preparation method is the same as in Example 1.
