[0010] Preferably, the base oil is a mixture of transformer oil and HVI500 base oil.

[0011] Preferably, the mixing temperature of the transformer oil and the HVI500 base oil is 60°C-85°C.

[0012] Preferably, the calcium sulfonate salt rust inhibitor is neutral barium dinonylnaphthalenesulfonate.

[0013] Preferably, the phenolic antioxidant is 2,6-di-tert-butyl-p-cresol.

[0014] Preferably, the ashless rust inhibitor is neutral calcium dinonylnaphthalenesulfonate.

[0015] Preferably, the alcohol ether is selected from one of diethylene glycol monobutyl ether, silicone oil or butanol.

[0016] Preferably, the oxidized paraffin can be replaced by lanolin.

[0017] The preparation method of the water-displacement type rust-proof oil composition comprises the following steps:

[0018] Step 1: HVI500 base oil and transformer oil are mixed and heated to 60°C-85°C;

[0019] Step 2, add lanolin or oxidized paraffin and stir until completely dissolved;

[0020] Step 3, adding calcium sulfonate salt rust inhibitor, ashless rust inhibitor, phenolic antioxidant, oxidized paraffin, and alcohol ether in sequence and stirring until completely dissolved;

[0021] Step 4: Filter with a 500-mesh filter bag.

[0022] Beneficial Effects
