Description

One kind can oil-soluble complex screw formula air compressor oil
Technical field
The invention belongs to technical field of lubricating oil is and in particular to one kind can oil-soluble complex screw formula air compressor oil.
Background technology
Air compressor oil is mainly used in the lubrication of compressor cylinder moving component and air bleeding valve, and rises antirust, anti-corrosion, close Envelope and cooling effect.Because compressor is constantly in high pressure, high temperature and the environment with the presence of condensed water (to air compressor machine), therefore Compressor oil should have excellent high-temperature oxidation stability, low tendency to soot, suitable viscosity and viscosity temperature characteristic and good Oil-water separativeness, resistance to rust and corrosion etc..The too low lubricating oil of viscosity is difficult to be formed sufficiently strong oil film, meeting accelerated wear test, contracting The service life of short parts.Conversely, lubricating oil viscosity is too high, internal friction can be increased, so that the specific power of compressor is increased, so that Increase power consumption and oil consumption, also easily in piston ring groove, form deposit on air valve, in exhaust passage etc..Compressor oil is in fortune It is also easy to produce emulsion in row, causes Oil-gas Separation unclear, oil consumption increases, simultaneously oily emulsified and make oil film breakdown, can cause Abrasion increases.
Base oil is undoubtedly the deciding factor of compressor oil lubricant effect, the especially base oil of Biodegradation Lubricating Oil Need to meet following standard:There is good dispersing and dissolving performance to additive, good cryogenic property, sufficient biodegradation Property, good greasy property, high-flash.Base oil for environmental friendly lubricant mainly has vegetable oil, synthetic ester, epoxidation Thing polymer, polyethers or isohydrocarbon etc..
Polyethers is that the monomers such as oxirane, expoxy propane, epoxy butane and oxolane occur open loop homopolymerization or copolymerization life The linear compound becoming.The performance of polyethers is closely related with its molecular structure, molecular backbone alkylene oxide type, ratio, end The type of base is all affected with distribution to some extent with the size of concentration, the hydrocarbon chain structure of initiator and length and pfpe molecule The performances such as their viscosity, viscosity index (VI), pour point, dissolubility and heat stability.In general, polyethers and mineral oil, synthesis hydrocarbon Immiscible.
Content of the invention
The technical problem to be solved is：Offer is a kind of to be had excellent anti-oxidative stability, resistance to emulsion, resists Rotten rust-preventing characteristic, fabulous defoaming and excellent viscosity temperature characteristic, can with mineral oil and mix can oil-soluble complex screw formula empty Air compressor oil.
For solving above-mentioned technical problem, the technical scheme that the present invention provides is：A kind of oil-soluble complex screw formula air pressure Contracting machine oil, according to the mass fraction, including raw material：
Described synthetic base oil A：According to the mass fraction, plant Oleum Brassicae campestriss 80-90 part and isopropanol 16-18 part, NaOH1.2-1.9 part, at 60-68 DEG C, is reacted 3-4 hour, is obtained vegetable oil acid isopropyl alcohol ester；Vegetable oil acid isopropyl alcohol ester again with 2-3 Part Et2Al2Cl3, 35～40 parts of isopropanol chloro-formates 55-60 DEG C, friedel-craft reaction 5-5.5 hour obtain base oil A；
(Polyalkyleneglycols (PAG), its essential building blocks is by oxirane for described poly alkylene glycol (EO), expoxy propane (PO), epoxy butane (BO) or oxolane (THF) composition.
The dynamic viscosity when 40 DEG C for the described oil-soluble poly alkylene glycol is 100000～150000mm2/s.
A kind of described oil-soluble complex screw formula air compressor oil is it is characterised in that it is preferred according to the mass fraction Consist of：
A kind of described oil-soluble complex screw formula air compressor oil is according to general preparation method system in industry Standby obtain.
Beneficial effect：Using amine and phenolic compound as antioxidant, high temperature ash-free antiwear agent is as antiwear additive, Pyrusussuriensiss , as antirust agent, the copolymer of acrylate and ether is as anti-foaming agent for sugar alcohol fatty acid fat.The oil-soluble complex screw being obtained Formula air compressor oil environmental friendliness, in this compressor oil, between each component, the compatibility is good, has excellent antioxidation peace The advantages of qualitative, resistance to emulsion, anti-corruption rust-preventing characteristic, fabulous defoaming and excellent viscosity temperature characteristic, is so as to performance indications reach No. 46 compressor oil standards, for air compression system plant equipment etc..
Specific embodiment
