Technical Field

The invention belongs to the technical field of lubricating oil of a steam turbine, and particularly relates to a turbine oil composition, a preparation method and application thereof.

Background

Turbine oil may have air ingress during operation, which may generate foam that may affect the formation of a lubricating film, worsen the lubrication conditions, and accelerate wear of parts. Therefore, turbine oils are required to have good anti-foaming properties.

When the steam turbine unit is in operation, steam does not leak into an oil system from a shaft seal tightly, oil and water are mixed to form emulsion, and the lubricating performance is affected, so that turbine oil is required to have good emulsification resistance.

In addition, turbine oils are also required to have good antioxidant properties and rust preventive properties.

One prior art turbine oil composition includes: 0.2-0.5 part of antioxidant, 0.05-0.1 part of metal deactivator, 0.04-0.1 part of antirust agent, 0.01-0.05 part of demulsifier, 0.003-0.005 part of antifoaming agent and the balance of base oil, wherein the demulsification performance of the base oil is 5-12 mins, and only slight rust can be generated at most in 24 hours under synthetic seawater, but the turbine oil composition has more components, so that the cost is higher and the economic benefit is not good.

The preferred mixture is the mixture of the two, the heat resistance of the alkyl phenyl-alpha-naphthylamine is good, and the compounded alkylated diphenylamine mutually plays a synergistic effect, so that the oxidation performance of the oil product is greatly improved.

In the above technical solution, preferably, the metal deactivator is at least one of an indole derivative, a benzotriazole derivative, or a thiadiazole derivative. Such as T551, Cuvan484, T561. The metal passivator is selected, so that the metal activity can be effectively inhibited, and the high-temperature corrosion tendency of oil products to metals is reduced.

In the above technical solution, preferably, the rust inhibitor is at least one of alkenyl succinic acid, alkenyl succinic acid ester, amino acid derivative, and amine, and alkenyl succinic acid amide derivative. Such as T746, T747, K1031, C4802. The antirust molecules form an adsorptive protective film on the metal surface, have certain solubilization function on water and polar substances, can replace the water on the metal surface and play a role in dehydration.

In the above technical solution, preferably, the rust inhibitor is at least one of alkenyl succinate, an amino acid derivative, and an amine.
