Above formulation types is used widely in many oil companies.
In a word, in above-mentioned document and patent, do not have one piece openly to control SULFURIZED CALCIUM ALKYL PHENATE WITH HIGH BASE NUMBER and high-alkali salicylate compositely proportional, do not have public use boronation thiophosphatephosphorothioate amine salt to improve the patent of composition resistance to abrasion yet.
The object of the present invention is to provide a kind of lubricant compositions that can satisfy lubricating requirement between large-sized low-speed cross-head diesel engine piston and the cylinder sleeve.
The invention provides a kind of large-sized low-speed cross-head diesel engine that can suppress effectively owing to the effect corrosive wear that causes of high-sulfur fuel and frictional wear to a certain degree, and can improve the high temperature detergency of oil product.The following component that said composition is assisted composition as the lubricated graininess oil and the conduct of major ingredient:
A: base of a pillar thiophosphatephosphorothioate amine salt (NSPN)
B: SULFURIZED CALCIUM ALKYL PHENATE WITH HIGH BASE NUMBER
C: high-alkali calcium salicylate
D: binonylphenol polyoxydivinyl ether (DNP)
E: the poly-rare succimide of isobutyl

Basis of the present invention is that SULFURIZED CALCIUM ALKYL PHENATE WITH HIGH BASE NUMBER and high-alkali calcium salicylate have preferable compatibleness, composition has good detergency and resistance to abrasion, boronation thiophosphatephosphorothioate amine salt particularly, the resistance to abrasion of composition is improved, and other use propertieies are had no adverse effects.
The structure of employed NSPN is as follows among the present invention:
Wherein: the R representative has the alkyl of 1-12 carbon atom;
R ' representative has the alkyl of 6-20 carbon atom.
It is to be reacted under certain condition by phosphide, sulfide and boride to make, its sulphur, phosphorus, nitrogen, boron content are respectively: 5.0-6.5 (m) %, 5.0-6.5 (m) %, 2.5-3.5 (m) %, 1.5-1.9 (m) % has good extreme pressure anti-wear and thermal oxidation stability.DNP in the composition can make oil product diffusion rapidly on cylinder sleeve, cooperatively interacts with zinc dialkyl dithiophosphate, NSPN in the composition, makes oil product have excellent abrasion resistance.Thereby determine that it is the key component of said composition.
R=C in the formula
9-18Alkyl, n=12-20.
It is the product that is made by binonylphenol and polyether reactant, can reduce the surface tension of oil product, makes oil product be diffused into the cylinder sleeve surface rapidly, has guaranteed the oil film on cylinder sleeve surface.
Other additives belong to known content, need not give unnecessary details at this.
In the composition among the present invention, six kinds of components of various additives (referring to A, B, C, D, E, F)) ratio determines that by four ball friction-wear tests, detergency strenuous test, diffustivity test etc. the actual applying working condition of lubricating oil has been simulated in these tests effectively.
During composition among the present invention is applicable to, the mineral oil of low-viscosity index.In the sufficient oil product of preparation, the effective level of each component is as follows:
