Abstract
The invention discloses a compressor oil composition. The compressor oil composition provided in the invention, which is capable of reducing the oleic acid content of a compressor by employing epoxy plant oil capable of reacting with oxidation products such as organic acids and alcohols generated by oxidizing the compressor oil, has excellent oxidization stability in addition to good lubrication property; and compared with the oil product without an auxiliary antioxidant, the oxidative induction time is increased more than one time so that the service life of the compressor oil is effectively extended.
Description
Technical field
The present invention relates to technical field of lubricating oil, particularly relate to a kind of lubricating oil composition for compressor.
Background technology
Compressor oil is the important lubricating oil product of a class, be widely used in each industry and civil area, the industrial booms such as weaving in recent years, iron and steel, petroleum chemistry, automobile, shipbuilding, compressor apparatus is to high pressure, long lifetime future development, as supporting oil product, require compressor oil constantly to increase the service life, therefore, compressor oil must have good oxidation stability except having good wear resistance.The main path that improves oil oxidation stability is to add oxidation inhibitor and anti-oxidant assistant agent.Oxidation inhibitor is the requisite additive of lubricating oil, and its kind is a lot, mainly comprises phenol type, amine type, phenolic ester type, monothioester type, phosphite type etc.But for the rising of high-voltage rotary long lifetime compressor oil due to operating temperature, the air mixed degree is large, and the characteristics such as long service life adopt traditional oxidation inhibitor to be difficult to satisfy service requirements.
Summary of the invention
The purpose of this invention is to provide a kind of compressor oil composition with good oxidation stability.
To achieve these goals, the present invention finds a kind of epoxidized vegetable oil material, and it can wait oxidation products to react with organic acid and the alcohol that the compressor oil oxidation generates, and lowers the compressor oil acid content, extends compressor oil work-ing life.Described epoxidized vegetable oil material refers to the reaction product of the two key initial ring oxidizing reactions of lipid acid in vegetables oil, be generally in vegetables oil the two keys of lipid acid and hydrogen peroxide, peroxyformic acid, Peracetic Acid etc. or its mixture and carry out epoxidation reaction, catalysts is zeolite, ion exchange resin, anhydrous sodium carbonate, (NH

2SO
4Or SnCl
2Deng, epoxidation reaction temperature is generally at 40～80 ℃, and reaction is at the two keys of lipid acid place's generation ether ring product of vegetables oil.The preparation of this type of material is prior art with obtaining, product commonly used such as epoxy soybean oil, epoxy rapeseed oil etc.
The present invention further provides a kind of compressor oil composition, it comprises take base oil weight as benchmark:
1.N-phenyl-a-naphthylamine, 0.01～5%;
2. octyl group/amyl group pentanoic, 0.01～5%;
3. epoxidized vegetable oil, 0.01～10%, preferred 0.02～1%, more preferably 0.08～0.5%;
4.N, N-di-n-butyl aminomethylene 124 Triazole, 0.01～1%;
5. the nitrogenous derivative of sulphur phosphoric acid, 0.01～1%;
6. dodecenylsuccinic acid, 0.01～1%;
7. poly-alpha olefins, 0.1～1%;
8. base oil, surplus.
Described base oil is hydrofining mineral distillate or its mixture, and 40 ℃ of kinematic viscosity are 15～150mm
2The cut of/s.
The present invention is by adopting the epoxidized vegetable oil that can wait oxidation products to react with organic acid and the alcohol of compressor oil oxidation generation, lower the compressor oil acid content, so compressor oil composition that provides, also has good oxidation stability except having good lubricity, compare with the oil product that does not use auxiliary antioxidant, oxidation induction period doubles above, has effectively extended compressor oil work-ing life.
Embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, and the epoxy soybean oil that adopts, epoxy rapeseed oil are the common product of epoxidized vegetable oil, but are not used for limiting the scope of the invention.
Embodiment:
By following formula (unit: % by weight), mix each raw material to even, 60 ℃ of mixing temperatures.
Choose commercially available compressor oil commonly used: 150 ℃ of rotary oxygen bomb method oxidation induction periods of Japanese bright dipping Dai Fenni (Daphne) rotary compressor oil test, it is 1384 minutes again.Can find out that also compressor oil composition provided by the invention has good oxidation-resistance.
As can be seen from the above embodiments, the embodiment of the present invention is by adopting the epoxidized vegetable oil that can wait oxidation products to react with organic acid and the alcohol of compressor oil oxidation generation, lower the compressor oil acid content, so compressor oil composition that provides, also have good oxidation stability except having good lubricity, as can be seen from the above table, compare with the Comparative Examples of not using auxiliary antioxidant, oxidation induction period doubles above, has effectively extended compressor oil work-ing life.
The above is only the preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
