The lubricating oil emulsion splitter composition, provided by the invention, can be used for improving the emulsion breaking performance of polyolefin synthetic oil.
Description
Technical field
The present invention relates to a kind of emulsion splitter composition and application thereof for lubricating oil.
Background technology
Polyolefine synthetic oil (PAO) is the synthetic oil of being made by alpha-olefin polymerization.The PAO of commercial use is mostly the oligopolymer of decylene-1, wherein may contain dipolymer, trimer, tetramer, pentamer and a small amount of superpolymer, and they are isomeric hydrocarbon structures of homogeneous.Each oligopolymer contains a two key, for improving its oxidative stability, and generally must be through hydrotreatment.Polyolefine synthetic oil is the kind of consumption maximum in synthetic hydrocarbon lubricating oil, is also synthetic oil performance good oil product relatively comprehensively.Polyolefine synthetic oil can be made the kind of multiple viscosity grade, flexibly choice for use.Polyolefine synthetic oil viscosity temperature characteristic is good, pour point is low, viscosity index is high, vaporization losses is little.After adding oxidation inhibitor, thermo-oxidative stability is high.Aromatic free in polyolefine synthetic oil, so nontoxic, non-stimulated to skin.The white oil of preparing with polyolefine synthetic oil can meet the specification requirement of food-level white oil.Polyolefine synthetic oil is good to the wetting property of skin and hair, can be used for makeup, skin lotion and hair conditioner.Polyolefine synthetic oil also has good electric insulating quality.The main drawback of polyolefine synthetic oil is general to the consistency of many sealing materials, can be compatible with the sealing material of resistance to mineral oil.
Along with lubricating oil product is to the future development of high-performance, more permanent usage period more, the Application Areas expanding day of PAO.The solvability of many conventional lubricating oil additives in polyolefine synthetic oil is not good, has affected the application of these additives in polyolefine synthetic oil, so the solubility property of additive in PAO is outstanding a, urgent need to solve the problem.
Some lubricating oil products, as Oil Film of Bearing Oil, turbine oil, turbine oil, hydraulic efficiency oil, gear oil, ship use intermediate speed tubular machine oil, ship lubricant oil, in use with water coolant, wash-down water, in water of condensation and environment, other forms of water and steam frequently contact.Emulsified if oil product does not have good demulsification performance, the oil product after emulsification can reduce and even loses lubrication, causes structure deteriorate, produces harmful acidic substance etching apparatus simultaneously, causes equipment breakdown.The metallic particles that moisture and wearing and tearing produce has accelerated again the deterioration by oxidation of oil product, makes oil product shortening in work-ing life.Therefore, in the specification of quality of many oil products, there is demulsification performance index.。The viscosity of oil product is larger, also larger to the retardation of the motion of dispersed phase drop, just more difficult aggegation of drop.This is also the reason that PAO lube product need to provide demulsification performance.Emulsion splitter is due to the hydrophilic amphoteric character of its oleophylic, and the solubility property in general lubricating oil makes a big difference according to its molecular structure, needs careful selection emulsion splitter.For PAO, the emulsion splitter simultaneously with raising oil product demulsification performance and excellent dissolution performance is the important additives of PAO lubricant formula.
