Abstract

The invention discloses a lubricating agent applicable to a closed type cycle diesel engine. Polyinternalolefin and polyol ester are compounded as base oil, and a plurality of composite additives are coordinated. The lubricating agent comprises an antioxidant preservative, an antirusting agent, an antioxidant, a metal deactivator, an anti-foaming agent, a demulsifying agent, a clearing agent, a dispersing agent, a friction modifier, and the like. The lubricating agent disclosed by the invention is suitable for being used by the closed type cycle diesel engine used as a prime motor of an electric generator.

Description

A kind of lubricant being applicable to closed cycle diesel

Technical field

The invention belongs to a kind of field of lubricant being applicable to closed cycle diesel.

Background technology

Closed cycle diesel (i.e. AIP device) is generator prime machine.For making diesel engine not having to work under air air feed situation, the air inlet gas of simulated air composition must be provided, making diesel engine ignition burning work.For this reason, the waste gas of being discharged by diesel engine is through CO ₂resorber absorption portion CO ₂gas, is not added appropriate oxygen again by absorption portion gas in waste gas, namely forms artificial atmosphere.But due to CO in this artificial atmosphere ₂content is always many than fresh air, makes the specific heat of combustion of artificial air lower than normal air; For ensureing that general standard diesel engine normally works under closed cycle state, generally in the gas of recirculation, adding appropriate monoatomic gas argon, making the artificial atmosphere that is mixed into consistent with normal air ratio of specific heat.Such diesel engine normally can work under closed cycle state, also at open type air for seasonable normal work, can realize open and close and share.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of lubricant being suitable for closed cycle diesel when closed cycle diesel uses as generator prime machine.

The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on poly-internal olefin and polyol ester compound, coordinate multiple composite additive, its each component and mass percent thereof are:

Component	Content (mass percent)
		Base oil	Surplus
Antioxidant preservative	2.0%～3.0%
		Rust-preventive agent	0.5%～1.5%
Kilfoam	0.001%～0.003%
		Metal passivator	0.8%～1.2%
Non-emulsifying agent	0.5%～2.5%
		Oxidation inhibitor	1.0%～3.0%
Purification agent	8.0%～10.0%
		Dispersion agent	10.0%～13.0%
Friction improver	2.0%～3.0%

Base oil is the poly-internal olefin of mass ratio 60% ~ 70% and the polyol ester compound of 40% ~ 30%.

Antioxidant preservative is the sulphur phosphorus secondary alcohol groups zinc salt of mass ratio 40% ~ 50% and the dialkyl dithiophosphoric acid oxygen molybdenum oil-soluble organic molybdenum compound of 60% ~ 50%.

Rust-preventive agent is dodecenylsuccinic acid ester.

Kilfoam is dimethyl silicone oil.

Metal passivator is the 124 Triazole derivative of mass ratio 60% ~ 50% and the dinonyldiphenylamine compound of 40% ~ 50%.

Non-emulsifying agent is amine and epoxy compounds condenses.

Oxidation inhibitor is the N-phenyl-a-naphthylamines of mass ratio 40% ~ 50% and the thiadiazoles derivative compound of 60% ~ 50%.

Purification agent is the low alkali value calcium mahogany sulfonate of mass ratio 40% ~ 30%, the high base number calcium mahogany sulfonate of 30% ~ 35% and 30% ~ 35% high base number synthesize sulfonic acid magnesium compound.

Dispersion agent is the polyisobutene succinimide (high nitrogen) of mass ratio 60% ~ 50% and the diene base succimide compound of 40% ~ 50%.

Friction improver is phosphoric acid ester.

A kind of lubricant being applicable to closed cycle diesel of the present invention, adopt oil based on poly-internal olefin and polyol ester compound, coordinate multiple composite additive, comprising: antioxidant preservative, rust-preventive agent, oxidation inhibitor, metal passivator, kilfoam, non-emulsifying agent, purification agent, dispersion agent, friction improver etc.Lubricant of the present invention is suitable for using as closed cycle diesel during generator prime machine.
