Abstract
The present invention is preparation process of machine lubricating oil with graphite/organic molybdenum compound as additive. The machine lubricating oil is prepared with graphite 0.3-10 wt%, liposoluble organic molybdenum compound 0.5-15 wt%, dispersant 4-6 wt% and base lubricating oil 70-95 wt%. The graphite is slightly expanded graphite prepared through an abrupt pressure reducing process, and the liposoluble organic molybdenum compound is molybdenum oxide dialkyl dithio phosphate. The graphite/organic molybdenum lubricating oil has the characteristic of the base lubricating oil maintained as well as functions of resisting wear, reducing friction, resisting extreme pressure friction, resisting oxidation, etc.
Description
Technical field
The present invention relates to a kind of preparation method of lubricating oil, particularly relate to a kind of by the power lubrication finish preparation method of graphite/organic molybdenum as additive.
Background technology
Frictional wear is the destruction of material and the major cause that mechanical means is scrapped in the world today.Lubrication technology is an effective means of reducing friction, reduce wearing and tearing, and the important means of lubrication technology is to use lubricant.Lubricant can be divided into liquid lubricant and solid lubricant etc. again.It is by adhering to or be coated on the lubricator of surface of friction pair, borrow process of friction and wear to form lubricated transfer film on to friction surface, improving the contact condition between friction pair, thereby played the wear-resistant effect of effective anti-attrition.
Graphite is a kind of good solid lubricant.Current existing use solid graphite is done the product of lubricating oil additive, and graphite has only been done simple vibration mill pulverizing to this series products or airflow milling is pulverized, and graphite particulate precipitates in base oil easily, and result of use is undesirable.
Organic-molybdenum can be used for lubricating oil additive, have wear-resistant, anti-attrition, anti-extreme pressure friction, etc. multiple function.Organic-molybdenum commonly used has dialkyl dithiophosphoric acid oxygen molybdenum, polyisobutenyl Succinic Acid molybdenum, hexyl phosphorodithioic acid oxygen molybdenum, carboxylamine molybdenum, molybdenum naphthenate etc.Friction oxidation takes place in organic-molybdenum preparation commonly used easily, and mechanical means is had certain corrodibility, so addition is subjected to certain restriction, and these defectives make it to give full play to the effect of organic molybdenum additive.
Summary of the invention
Discover that graphite and organic-molybdenum mixing energy are alleviated the friction oxidation of organic molybdenum lubricating film, improve its work-ing life.Reason is steam and the oxygen in the graphite energy preferentially adsorbed atmosphere, thereby can suppress organic-molybdenum generation oxidation deactivation.The preparation method of graphite/organic molybdenum lubricating finish of the present invention provides a kind of and has made the lubricating finish preparation method of additive with graphite, organic-molybdenum, and it has overcome the defective of prior art.
Through the research experiment of several years, final preferred with expanded graphite and oil-soluble organic molybdenum dialkyl dithiophosphoric acid oxygen molybdenum as lubricating oil additive.That its finished product have is energy-efficient, antifriction, the wearing and tearing of anti-extreme pressure, effect such as anti-oxidant, is the optimal lubricating oil additive that people use.With the motor car engine is example: vehicle motor is when starting, and all in the oil pan of engine, the short period of time runs out of oil to lubricating oil in the engine, produces the oil starvation friction.But the trace graphite and the organic-molybdenum short period of time that remain in the engine surface of the work guarantee lubricated; When the engine running overload, graphite and organic-molybdenum can be brought into play the advantage of anti-extreme pressure wearing and tearing, thereby have guaranteed that engine normally moves.
The technical solution adopted for the present invention to solve the technical problems is: a kind of preparation method of graphite/organic molybdenum lubricating finish is characterized in that: the weight percent component is as follows: graphite 0.3～10%, oil-soluble organic molybdenum 0.5～15%, dispersion agent 4～6%, lubricating base oils 70～95%; Graphite adopts microdilatancy graphite; Oil-soluble organic molybdenum adopts dialkyl dithiophosphoric acid oxygen molybdenum.The expansion process of microdilatancy graphite adopts the prominent graphite expansion technology of losing of pressure.
The expansion process of microdilatancy graphite is in the prominent mistake of pressure graphite expansion equipment, at 110 °～160 ℃ temperature, 0.3～0.8MPa/CM
2Under the condition of pressure, the rapid decompression expansion produces.
The graphite/organic molybdenum lubricating finish also possesses wear-resistant, anti-attrition, anti-extreme pressure friction, multiple function such as anti-oxidant except that the primary characteristic that keeps lubricating base oils.Its beneficial effect is: we use the cargo truck of different model to do control experiment, the automobile that uses the graphite/organic molybdenum lubricating finish is than the automobile that uses traditional lubricating oil, fuel economy oil 5～15% reduces 2～3 times of component wears, reduces by 1～8 decibel of mechanicalness noise.Have high temperature resistant (oil temperature), anti-extreme pressure wearing and tearing, the active power of increase engine, the pollution emission of reduction engine, the advantages such as stopping property of enhancing engine have prolonged the work-ing life and the engine oil replacement cycle of motor car engine.
Embodiment
For make graphite additive in lubricating oil, do not precipitate, scattered, need to carry out microbulking and handle graphite, be processed into microdilatancy graphite.The expansion process of microdilatancy graphite is the graphite with purity 99.9%, be milled to granularity 1～3 μ M with micronizer mill after, the graphite microparticles that contains certain natural moisture content, join in the prominent mistake of the pressure graphite expansion equipment.Sealing equipment, and in equipment, fill the compression air, begin heating.When the temperature of graphite reaches 110 °～160 ℃, fill the compression air in the equipment and reach 0.3～0.8MPa/CM
2, kept 10 minutes.Throw open valve then, the equipment internal pressure of making discharges suddenly, at this moment because the unexpected release of temperature and pressure just makes the crystal lattices of graphite loose, forms microdilatancy graphite, and the moisture content in the graphite is also most of to be discharged.And then enter the loft drier drying, just reached service requirements.
In reactor, add the lubricating base oils temperature and keep 50～60 ℃, add dispersion agent T161, stirred 10 minutes, oil-soluble organic molybdenum dialkyl dithiophosphoric acid oxygen molybdenum and microdilatancy graphite are added in the reactor successively, stir homogeneous, filtration, just become the graphite/organic molybdenum lubricating finish through blending.
In concrete the application, engine oil refuels for the first time, and the addition of graphite and organic-molybdenum can be controlled in 5～15 the scope; The additional oiling of engine oil, the addition of graphite and organic-molybdenum can be controlled in 0.3～2.0% the scope.
