Description
Technical field
The present invention relates to a kind of lubricating oil composition, particularly a kind of antioxidant property good, can reduce greasy filth and generate trend, be fit to the lubricating oil composition that screw air compressor uses.
Background technology
Compressor is a kind of pressurized gas that is used for, and improves the machinery of gaseous tension or delivering gas.Along with the development of production technology, kind and the structure formation of compressor are increasing.Nowadays, the compressor of all kinds and specification is widely used in petrochemical complex, machinofacture, and civil construction, mining is metallurgical, communications and transportation and national defence, medical treatment, fields such as weaving food.Prevailing screw air compressor in compressor, used lubricating oil are under the high temperature and high pressure environment and contact for a long time with air, and lubricating oil is easily oxidized, cause that oil viscosity, acid number increase and greasy filth increases, and cause the operation troubles of compressor.Therefore, need to solve the high temperature antioxygen property that how to improve screw air compressor lubricating oil.
It is 200510048003.3 rotary jetting air-compressor lubricating oil and preparation method that Chinese invention patent discloses application number, used aromatic amine type high-temperature antioxidant in the prescription, compound use 2.6-ditertbutylparacresol of while, tritolyl phosphate and 124 Triazole fatty amine salt, wherein phosphate ester additive uses as oiliness improver.
It is 200510026494.1 a kind of synthetic air compressor oil that Chinese invention patent discloses application number, the component of invention comprises that low carbon residue, the higher synthesizing ester oil of biodegradable rate are main base oil, polyalphaolefin, antioxidant additive, extreme pressure anti-wear additives, defoamer, rust-preventive agent, non-emulsifying agent or metal passivator, and these invention characteristics are to be base oil and to use aromatic amine/phenol type antioxidant system with aromatic ester/poly-a-olefin oil.
It is 200910046629.9 a kind of composite synthetic air compressor oil that Chinese invention patent discloses application number, comprise two different (C8～13) alkyl straight-chain diester 15～20%, synthetic poly-a-olefin oil 5～10%, two iso-alkyls (C8～13) phthalic ester 72～74%.This invention is base oil with aromatic ester, poly-a-olefin oil still and uses aromatic amine, phenol type antioxidant system.
It is 200710175271.0 compressor oil composition that Chinese invention patent discloses application number, with hydrogenation Dormant oils base oil, ashless dispersant, the combination of half hindered phenol type antioxidant or amine type oxidation inhibitor and half hindered phenol type antioxidant, this invention antioxidant systems are principal character with aromatic amine/phenol type antioxidant still.
Summary of the invention
The object of the present invention is to provide a kind of screw air compressor oil compositions, improve oxidation stability, effectively suppress greasy filth and generate long service life.
Technical solution of the present invention is: a kind of Screw Air Compressor Oil composition, by base oil weight 100%, each component content is: high-temperature antioxidant 1～5%, extreme pressure anti-wear additives are 0.01～5%, corrosion inhibitor 0.01～0.5%, rust-preventive agent 0.01～0.5%.
Wherein high-temperature antioxidant is by amine type oxidation inhibitor, phenol type antioxidant with phosphite type oxidation inhibitor three is compound constitutes amine type oxidation inhibitor: phenol type antioxidant: phosphite type oxidation inhibitor part by weight is 20: 30: 50～50: 30: 20.
Described base oil is the composition of III class hydrogenated oil or Poly alpha Olefins (PAO) (PAO) synthetic oil or III class hydrogenated oil and Poly alpha Olefins (PAO) (PAO).
Described phosphorous acid ester is the Hinered phenols phosphorous acid ester.
Described extreme pressure anti-wear additives is phosphoric acid ester or phosphorous acid ester or phosphate amine salt or thiophosphatephosphorothioate.
Described rut preventives is 124 Triazole or thiophene two types or tetrahydroglyoxaline rut preventives.
Described rust-preventive agent is organic acid or the agent of acid amides Ashless stain-resistant.
The liquid-phase oxidation of lubricating oil is the autocatalytically oxidising process, is the chain reaction mechanism that is caused by free radical.In the build phase of chain, two related reactions are the autocatalytically oxidizing reactions that circulate, carry out repeatedly.At the hydroperoxide ROOH that build phase produces, be unsettled, can further decompose the generation free radical, then chain-react.Slow down or stop oxidation of lubricating oil reaction, necessary: (1) reacts away the peroxylradicals (ROO) that the chainpropagation stage produces, the terminating chain reaction; (2) hydroperoxide decomposition ROOH is the stable product of non-free radical, stops or slow down the generation of branch reaction.Phenols and amine antioxidants belong to free radical terminator together, have anti-oxidant synergy between the two, improve the whole antioxidant property of additive system.
Though and phosphite ester compound does not possess the ability that catches peroxylradicals, can hydroperoxide decomposition, studies show that each phosphite molecule can resolve into 6 hydroperoxide molecules under the room temperature.Phosphorous acid ester is as auxiliary antioxidant, and it can reduce hydroperoxide for pure, and self then is oxidized to phosphoric acid ester.
The reaction mechanism that phosphorous acid ester is caught peroxy radical is shown below:
ROOH+(R′O)
3P→(R′O)
3P＝O+RO.
Characteristics of the present invention are: phosphite type oxidation inhibitor is introduced in the screw compression machine oil, with phenol and the collaborative use of amine type oxidation inhibitor, compare with the phenol type antioxidant system with amine commonly used, can significantly improve the antioxidant property of oil product, greasy filth generates trend and also is well controlled, and is applicable to hydrogenated oil, PAO synthetic oil and semi-synthetic oil to be the screw compression machine oil of base oil.
Embodiment
The preparation method of present embodiment: base oil is squeezed into blending kettle, and the listed ratio of according to the form below adds additives such as oxidation inhibitor, extreme pressure anti-wear additives, antirust anti-corrosion additive successively, is heated to 60～80 ℃, and constant temperature stirs 1～2h, is cooled to 50 ℃ and filters and packages and namely get product.
Adopt the oxidation corrosion test method that the antioxidant property of oil product is measured, judge the quality of oil product antioxidant property according to situations such as oil viscosity, acid number variation and greasy filth after the oxidation.
Compare with comparative example, the compound oxidation susceptibility of use phosphorous acid ester and phenol/amine type oxidation inhibitor obviously improves, and oil viscosity increases obviously reduction after the oxidation, and acid number increases also less, and does not have the greasy filth generation, and comparative example has greasy filth.In embodiment 2, base oil is replaced with synthetic polyalphaolefin, performance is further promoted.
Above embodiment is just for this patent is further specified, and in patent statement scope, any composition and proportioning all are feasible.
