Abstract
The invention discloses a liquid composition of accessory ship diesel lubricate, which is characterized by the following: adopting middle basic oil as main component; mating fitful high-alkaline value calcium naphthenate, disuccinimide, dioctyl dithio-zinc phosphate, middle-alkaline alkyl calcium salicylate, high-grade lipoamide, polyoxypropylene polyoxyethylene block-typed polyether and silicon oil; allocating the system oil through scientific method.
Description
Technical field:
The present invention relates to a kind of the lubricated of low speed two-stroke cross-head high-power diesel engine crank axle case that be adapted to, also be applicable to lubricated fluid compositions such as the secondary machine diesel engine of boats and ships.
Background technology:
The main effect of engine with outside guide crankcase oils (system oil) be lubricate, sealing, peace and quiet, neutralizing acid and cooling.Conventional formulation generally adopts the manufacturing of high viscosity index (HVI) paraffin base oil.In order to prevent in the system oil that additive meets water hydrolysis, emulsification, often few with or without the two octyl group zinc dithiophosphates (ZDDP) of oxidation and corrosion inhibitor, thereby cause influencing the oil product antioxidative stabilizer.Antirust function weakens, and carbon deposit is hard, difficulty is removed, and needs to strengthen metal detergent content.As a result, cause the system oil wear resistance not ideal enough again.
Summary of the invention:
The objective of the invention is to drawback, a kind of the lubricated of low speed two-stroke cross-head high-power diesel engine crank axle case that be adapted to is provided, also be applicable to lubricated ship lubricant oils such as the secondary machine diesel engine of boats and ships at said system oil.
The present invention, base oil by 93～96% and 4～7% additive are formed, and additive is made up of following component:
High base number calcium naphthenate 1.2～2.0%;
Two succimides 0.75～1.0%;
Two octyl group zinc dithiophosphates 0.5～1.0%;
Middle basicity-value calcium alkyl salicylate 1.5～2.9%;
Fatty amide 0.03～0.05%;
Polyoxyethylene polyoxypropylene block type polyethers 0.02～0.05%;
Silicone oil 10～20ppm,
Wherein, the molecular formula of fatty amide is R-CONH
2, wherein, R is C
16～22Alkyl.
The present invention, described base oil is made up of intermediate base base oil and paraffin base oil, and its proportioning is: the intermediate base base oil: paraffin base oil=50～75: 25～50, and by 100 ℃ of 10mm
2/ s～30mm
2Composite the forming of/s different viscosity oil.
The present invention is a main component owing to adopt the intermediate base base oil, has carbon deposit simultaneously and loosens, and metal detergent content is few, the characteristics that abrasion resistance improves.
The present invention is R-CONH owing to introduce structure
2The multi-functional Ashless stain-resistant agent of the novel import fatty amide of (R is an alkyl), this rust-preventive agent not only has good rust-preventing characteristic (consumption few 0.03～0.05%, medium about 30000 yuan/ton of price), resistance to emulsion and thermostability, have synergistic effect when cooperating with an amount of ZDDP simultaneously, further improve the antioxidative stabilizer of system oil.In addition, because R-CONH
2Be a kind of organic weak base, in system oil with its oil in additive mutually exclusive hidden danger does not take place, do not have an effect, when system is in weak acid, do not have an effect yet, but high acid value occurs inorganic acid (HNO is particularly arranged when system

4Deng) adsorbable salify when occurring, this has just improved the acid neutralization capacity of system oil indirectly, avoids ZDDP (because of acid number increases) hydrolysis to cause the phenomenon of system oil emulsion deterioration (abrasion resistance decline).Good rust-preventing characteristic, oilness and emulsion resistance branch water-based, filterability are principal character of the present invention.
Embodiment:
The preparation of this ship lubricant oil can be formulated by the additive of 95% base oil and 5%.Wherein: base oil is by 65: 35 intermediate base base oil and paraffin base oil and by 100 ℃ of 10mm
2/ s～30mm
2Composite the forming of/s different viscosity oil; Additive then comprises following component:
High base number calcium naphthenate 1.5%;
Two succimides 0.8%;
Two octyl group zinc dithiophosphates 0.8%;
Middle basicity-value calcium alkyl salicylate 1.8%;
Fatty amide 0.05%;
Polyoxyethylene polyoxypropylene block type polyethers 0.05%;
Silicone oil 10～20ppm.
This composition is modulated in the stainless steel blending kettle.Blending kettle should have chuck heating and temperature controllable.Modulation order is: at first add base oil, heat up, stir.In stirring, drop into fatty amide (R-CONH successively
2), high base number calcium naphthenate, two succimide, middle basicity-value calcium alkyl salicylate, two octyl group zinc dithiophosphate (ZDDP), insulated and stirred is 0.5～1 hour after temperature rises to regulation technological temperature (60～70 ℃), add polyoxyethylene polyoxypropylene block type polyethers and silicone oil at last, leave standstill filtration, the packing of can lowering the temperature through after the assay was approved.
The physical and chemical index of ship lubricant oil is as shown in the table:
