Rotary jetting air-compressor lubricating oil and preparation method
Technical field:
The present invention relates to the air-compressor lubricating oil technical field, exactly it is that a kind of rotary jetting is slide plate and screw air compressor lubricating oil and preparation method
Background technology:
The air compressor oil of Shi Yonging was kept use by some anti-oxidative stabilities, rust-preventing characteristic and oilness that mineral oil itself is had fully in the past.
Owing to the development of compression mechanism technology for making, in compressor oil of new generation, introduce shield phenol type antioxidant and zinc dialkyldithiophosphatype type high temperature antioxygen, anti-rotten, anti-wear agent compound prescription in recent years, thereby improved the quality of air compressor oil.But because the zinc dialkyl dithiophosphate additive in this prescription can decompose under long-term oxygen enrichment and high-temperature condition, in case and the decomposing phenomenon generation, just can form chain reaction, cause oil product to degenerate, the settling surge, thus make the air compressor machine cisco unity malfunction.All there is this problem such as domestic and international some famous brand like product.Particularly the lubricating oil that uses of rotary jetting (slide plate and screw rod) air compressor mostly is imported product greatly, cost an arm and a leg, and domestic reference abroad fill a prescription the product made and external product mutually specific mass also have certain distance.Chinese patent once disclosed the prescription and the preparation method of several air-compressor lubricating oils, disclose the patent of invention that a kind of name is called " air compressor oil composition " as China Patent No. 92102699, but its prescription and technology and technique effect and the present invention are inequality.
Summary of the invention:
The purpose of this invention is to provide a kind of rotary jetting air-compressor lubricating oil and preparation method.The specialist additive and its preparation method of this lubricating oil are provided simultaneously.
The present invention uses several additives to add by a certain percentage in the base oil and makes rotary jetting (slide plate and screw rod) air compressor oil, and this compressor lubricant oil has good thermal oxidation stability, rust-preventing characteristic, resistance to emulsion.Join in different types of base oil after only adjusting simultaneously the ratio of three main additive wherein not changing the additive therefor kind, just can make rotary jetting (slide plate and the screw rod) air compressor oil of light load (DAG), middle load (DAH), three kinds of different use propertieies of heavy loading (DAJ) respectively, thereby just can be respectively applied for the lubricated and cooling of rotary jetting (slide plate and the screw rod) air compressor that requires the use different performance.
Gentle/oil temperature that light load rotary jetting (slide plate and screw rod) air compressor oil (DAG) is mainly used in exhaust is less than 90 ℃, the lubricated and cooling of the rotary jetting of working under exhaust pressure<800Kpa condition (slide plate and screw rod) air compressor.
In load rotary jetting (slide plate and screw rod) air compressor oil (DAH) be mainly used in exhaust gentle/oil temperature is less than 100 ℃, exhaust pressure 800~1500Kpa; Or exhaust gentle/100~110 ℃ of oil temperatures, the lubricated and cooling of the rotary jetting of working under exhaust pressure<800Kpa condition (slide plate and screw rod) air compressor.
Heavy loading rotary jetting (slide plate and screw rod) air compressor oil (DAJ) is mainly used in exhaust gentle/oil temperature>110 ℃, exhaust pressure<800Kpa or exhaust be gentle/oil temperature 〉=100 ℃, and the lubricated and cooling of the rotary jetting of working under exhaust pressure 800~1500Kpa condition (slide plate and screw rod) air compressor.
Because this compressor oil is in oxygen enrichment and comparatively high temps simultaneously and the working conditions of depositing for a long time, requiring this oil to possess has good thermal oxidation stability, otherwise can produce a large amount of settlings (carbon deposit) and make air compressor carbon deposit and obstruction, thereby set off an explosion and machine " locking ".Oil product in use can be subjected to the pollution of water in air, so require to have good resistance to emulsion and rust-preventing characteristic, requiring in addition has provide protection to copper and its alloy.Therefore only above-mentioned requirements can not be satisfied, multiple additive must be used with respective performances by base oil.
Do not contain the zinc dialkyldithiophosphatype type additive in rotary jetting of the present invention (slide plate and screw rod) the air compressor oil additive compound prescription, and be to use aromatic amine type high-temperature antioxidant, described different with the former.Simultaneously compound use 2.6 1 ditertbutylparacresols, tritolyl phosphate and 124 Triazole fatty amine salt have improved the thermal oxidation stability of oil product greatly, and these are different fully with rotary jetting (slide plate and screw rod) air compressor oil before this.
