Abstract
The invention belongs to the technical field of lubricating oil and particularly relates to lubricating oil for a marine internal combustion engine. The lubricating oil consists of base oil and lubricating oil additives and is particularly prepared from the following raw materials in parts by weight: 80-90 parts of base oil, 1-3 parts of a cleaning dispersing agent, 0.5-1.5 parts of a friction moderator, 0.5-0.7 part of an anti-rusting agent, 0.5-1.5 parts of a pour point depressant, 0.1-0.3 part of a viscosity index improver, 1-3 parts of an anti-foaming agent and 0.3-0.5 part of an preservative. By virtue of the raw materials, the wear resistance, oxidation stability resistance and cleaning and dispersing performance of the lubricating oil can be improved, so that the energy is saved, and the friction is reduced; furthermore, the service life of the marine internal combustion engine can be prolonged, the energy consumption can be reduced, and the environmental pollution can be obviously reduced; the lubricating oil has remarkable economic and social benefits.
Description
Technical field
The invention belongs to technical field of lubricating oil, be specifically related to a kind of marine diesel lube.
Background technology
Lubricating oil is generally made up of base oil and additive two portions.Base oil is lubrication main body of oil, and decide the essential property of lubricating oil, additive then can make up and improve the deficiency of base oil aspect of performance, gives the performance that some is new, is the important component part of lubricating oil.Lubricating oil is used in all kinds mechanically to reduce friction, protection machinery and the liquid lubricant of workpiece, mainly play lubrication, cooling, antirust, clean, seal and the effect such as buffering.But mechanical transmission kind is a lot, also not identical to the requirement of lubricating oil, as oil engine needs high temperature resistant, dispersion greasy filth to the requirement of lubricating oil, reduce oil film action.
Summary of the invention
The present invention in order to object be to provide a kind of marine diesel lube.
Technical scheme of the present invention is: a kind of marine diesel lube, it is made up of base oil and lubricating oil additive, is specifically made up of the proportioning raw materials of following parts by weight: base oil 80-90 part, detergent-dispersant additive 1-3 part, friction negative catalyst 0.5-1.5 part, rust-preventive agent 0.5-0.7 part, pour point depressant 0.5-1.5 part, viscosity index improver 0.1-0.3 part, kilfoam 1-3 part, antioxidant preservative 0.3-0.5 part.
Detergent-dispersant additive of the present invention can be overbased calcium alkyl-salicylate;
Rust-preventive agent of the present invention can be dodecenylsuccinic acid;
Pour point depressant of the present invention can be vinyl acetate;
Viscosity index improver of the present invention can be polyvinyl n-butyl ether;
Kilfoam of the present invention can be methyl-silicone oil;
Antioxidant preservative of the present invention can be dipentylamino zinc formate.
A kind of preparation method of marine diesel lube, in a heat-resisting container, add base oil, detergent-dispersant additive, friction negative catalyst, rust-preventive agent, pour point depressant, viscosity index improver, kilfoam, antioxidant preservative successively, be heated to 60-70 DEG C while stirring, maintain about 20min, make material even, obtain the liquid of a thickness.
The effect of additive of the present invention is as follows:
Detergent-dispersant additive: during internal combustion engine, engine oil will bear the severe condition of high temperature, high pressure, and with the oxygen in air and metallic contact, be thus oxidized, condensation, the reaction such as decomposition, form greasy filth, carbon deposit, bituminous matter, colloid and organic acid etc. thus.Fuel combustion is incomplete, and the carbon deposit of generation is deposited on engine part, also makes engine operation worsen.Add the object of detergent-dispersant additive, will by the solubilising of peace and quiet point quiet dose, dispersion, acid neutralization and cleaning function, make to be deposited on greasy filth on mechanical surface and carbon deposit washs, and make their dispersions and be suspended in oil to be removed by strainer, thus make piston and other component keep clean, normally work.
Friction negative catalyst: reduce frictional coefficient, make the round and smooth mitigation of lubrication friction, very thin lubrication film strength when increase mixed lubrication or boundary lubrication and oilness, thus under the condition that friction is very little, reduce friction and lose to save power.
Rust-preventive agent: there is infiltration rust cleaning, loosen lubrication, resist the performances such as burn into protection metal.
Viscosity index improver: effect is along with the rising of temperature makes oil body increase.
Foam preventer: be prevent from producing bubble in lubricating oil.Its action principle is, changes the surface tension of foam and makes small bubbles set become air pocket, make bubbles burst and reach froth breaking effect.
Antioxidant preservative: anti-oxidant, protection against corrosion, extends the work-ing life of lubricating oil.
Beneficial effect: resistance to abrasion and anti-oxidative stability, quietness and the dispersing property that can improve lubricating oil, thus realize energy-conservation antifriction.And the work-ing life of marine engine can be improved, reduce energy consumption, reducing environmental pollution has obvious effect, has aobvious person's economical, societal benefits.
