Description

Marine lubricant compositions and application thereof
Technical field
The present invention relates to a kind of marine lubricant compositions and application thereof.
Background technology
Marine lubricant mainly includes marine cylinder oil, ship lubricant oil and MARINE MEDIUM SPEED ENGINE OIL three major types, this three major types Oil product, for the lubrication of marine engine system, also has other little kind lubricating oil such as steam turbine oils, hydraulic oil, gear oil, cold Freeze machine oil, compressor oil, rail oil, stern tube shaft oil etc. and be mainly used in the above-decks equipment of boats and ships.MARINE MEDIUM SPEED ENGINE OIL is owing to using ring The particularity in border, contacts with water and becomes inevitable problem, therefore it is required that bunker oil to have good water separable performance and antirust Property.For meeting the use requirement of engine of boat and ship, oil product must have sufficiently high base number, good antioxygen anti-corrosive properties, peace and quiet point Dissipate property etc..MARINE MEDIUM SPEED ENGINE OIL product is classified by different viscosities grade, different base number, and the essential condition of selection is and fuel Oil sulfur content matches.If oil product base number is too small, lubricating oil acid neutralization capacity deficiency can cause engine corrosion, abrasion；Alkali Being worth excessive, metal ash is high, will also result in abrasive wear, and too high base number also can affect oil product cleansing performance.Scientific and normal Select bunker oil product can effectively protect electromotor, increase the service life.Such as document CN1524936A discloses a kind of by height The double octyl group Alkaline Zinc of middle calcium alkylbenzensulfonates, alkyl sodium sulfate phenol calcium, polyisobutene succinimide, sulfur phosphorus, phosphoric acid value amine with The ship use intermediate speed tubular diesel engine oil composition of the composition such as epoxide condensation substance, can calculate oil product base number from disclosure 30～50mgKOH/g.Document CN102086420A discloses a kind of ship use intermediate speed tubular diesel engine oil composition, said composition master To be made up of the additive such as alkyl sodium salicylate, calcium sulfenyl phenolate, from the base number of this inventive composition seen from embodiment 30～ 50mgKOH/g.Document CN103184091A discloses a kind of lubricating oil composition used for a ship universal type diesel engine, and in compositions, high temperature is clear Net agent by alkyl monosulfide phenates 15～25%, low alkali value sulfoacid calcium 14～25%, alkylsalicylate surplus is compound constitutes, it is possible to Meeting naval vessels two-stroke and four strokes, Medium and high speed engine uses requirement simultaneously.Document CN1524936A and CN102086420A Related products are applicable to S content 2.0～the fuel oil of 3.5%, do not mate with the S content fuel oil less than 0.5%.
Additionally, storage stability and the compatibility are another important performances embodying oil quality, storage stability is good Oil product long-term storage will not produce precipitation, go bad, under special circumstances can also be mixed with other brand oil products.Presently commercially available peculiar to vessel The brand of oil is more, and due to the difference of formulation composition between the different trades mark, oil product storage stability is very different, and storage stability is relatively Its compatibility of oil product of difference is not the best enough, has bigger infringement to electromotor.The optimum method solving this problem is exactly to tie from formula It is adjusted on structure, selects to meet bunker oil and use the technical scheme requiring to improve again oil product stability.The most not See there is the document report introduced specially in terms of bunker oil storage stability and the compatibility.
Summary of the invention
One of the technical problem to be solved is to provide a kind of marine lubricant compositions being not added with antirust agent, keeps away That has exempted from antirust agent adds the negative interaction to oil product point aqueous energy.Said composition has good rust-preventing characteristic, meets marine engine Oil uses requirement, and solves bunker oil and be frequently run onto storage stability, consistency problem.Technology to be solved by this invention is asked The two of topic are to provide the purposes of a kind of marine lubricant compositions corresponding with solving one of technical problem.
For solving one of above-mentioned technical problem, the technical solution used in the present invention is as follows: a kind of marine lubricant compositions, It is made up of following component in terms of parts by weight:

B) 2.0～5.0 parts selected from single polyisobutene succinimide, double polyisobutene succinimide or poly isobutyl At least one in alkene succimide；
C) the sulfur phosphorous zinc salt of 1.0～3.0 parts and the mixture of ashless oxidation inhibitor；
D) at least one in polyalphaolefin or polymethacrylates of 0.3～1.0 part；
E) at least one in dimethicone or non-silicon type antifoamer of 0.004～0.2 part；
F) base oil of surplus；
Described marine lubricant compositions does not contains antirust agent.
In technique scheme, in described component a), alkyl monosulfide phenates is (4.0 with the weight ratio of over base sulfosalt ～3.0): (3.0～1.5), alkyl monosulfide phenates is (2.5～1.5) with the weight ratio of low alkali value sulfonate: (3.0～1.5).
In technique scheme, it is preferable that described component b) is selected from single polyisobutene succinimide, double focusing isobutene. fourth At least two in imidodicarbonic diamide or many polyisobutene succinimides.
In technique scheme, the weight ratio of component b) and component a) is (3.5～2.0): (2.0～1.0).
In technique scheme, in described component c), the weight ratio of sulfur phosphorous zinc salt and ashless oxidation inhibitor be (4.0～ 3.0): (2.0～1.0).
In technique scheme, described ashless oxidation inhibitor selected from amine type antioxidant, phenol type antioxidant, phenol amine type antioxidant, At least one in thiophene type antioxidant or carbaminate kind antioxidant.
In technique scheme, it is preferable that described component d) is selected from polymethacrylates；Described component d) is in compositions In be calculated as 0.5～0.8 part with parts by weight.
In technique scheme, it is preferable that described component e) is selected from non-silicon type antifoamer；Described component e) is in the composition It is calculated as 0.005～0.1 part with parts by weight.
