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 compsn and application thereof that is used for lubricating oil.
Background technology
Polyolefine synthetic oil (PAO) is the synthetic oil of being processed by alpha-olefin polymerization.The PAO of commercial use mostly is the oligopolymer of decylene-1, wherein possibly contain dipolymer, trimer, tetramer, pentamer and a spot of superpolymer, and they are isomeric hydrocarbon structures of homogeneous.Each oligopolymer all contains a two key, for improving its oxidative stability, and generally must be through hydrotreatment.The polyolefine synthetic oil is the maximum kind of consumption in the synthetic hydrocarbon lubricating oil, also is the relatively more comprehensive good oil product of performance in the synthetic oil.The polyolefine synthetic oil can be processed the kind of multiple viscosity grade, can select flexibly to use.Polyolefine synthetic oil viscosity temperature characteristic is good, pour point is low, viscosity index is high, vaporization losses is little.Thermo-oxidative stability is high after adding oxidation inhibitor.So aromatic free in the polyolefine synthetic oil is nontoxic, non-stimulated to skin.Can meet the specification requirement of food-level white oil with the white oil of polyolefine synthetic oil preparation.The polyolefine synthetic oil is good to the wellability of skin and hair, can be used for makeup, skin lotion and hair conditioner.The 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 anti-MO.
Along with lubricating oil product develops to high-performance more, the direction of more permanent usage period, the Application Areas of PAO enlarges day by day.The solvability of many oil dopes commonly used in the polyolefine synthetic oil is not good, has influenced the application of these additives in the polyolefine synthetic oil, so the solubility property of additive in PAO is outstanding, as to be badly in need of a solution difficult problem.
Some lubricating oil products; Like kelmet oil, turbine oil, turbine oil, hydraulicefficiency oil, gear oil, ship use intermediate speed tubular machine oil, ship lubricant oil; In use with water coolant, wash-down water, other forms of water and steam frequently contact in water of condensation and the environment.By emulsification, the oil product after the emulsification can reduce even lose lubrication if oil product does not have good demulsification performance, causes structure deteriorate, produces deleterious acidic substance etching apparatus simultaneously, causes equipment breakdown.The metallic particles that moisture and wearing and tearing produce has quickened the deterioration by oxidation of oil product again, makes oil product shortening in work-ing life.Therefore, in the specification of quality of many oil products the demulsification performance index is arranged all.。The viscosity of oil product is big more, and is also big more to the retardation of the motion of dispersed phase drop, just more difficult aggegation of drop.This also is the reason that the PAO lube product need provide demulsification performance.Emulsion splitter is owing to the hydrophilic amphoteric character of its oleophylic, and the solubility property in general lubricating oil has very big difference according to its molecular structure, needs careful selection emulsion splitter.For PAO, having the emulsion splitter that improves oil product demulsification performance and excellent dissolution performance simultaneously is the important additives of PAO lubricant formula.
