Step 2: by 45 parts of mineral base oils, 28 parts of polyalphaolefins, 23 parts of phosphite esters and 7 parts of polyalkylene glycol inputs In stirred tank, stirred tank is heated to 70 DEG C, and it is 100-700rpm to control mixing speed, stirring 3h obtains uniformly mixed answer Close base oil；
Step 3: the extreme-pressure anti-wear micro mist obtained in step 1 will be sequentially added in the composite foundation oil obtained in step 2 5 parts and 0.8 part of anti-emulsifying compound drug, 3 parts of 2 parts of benzothiazole or derivatives thereof, 2 parts of thioether phenol and fluorinated silicone oil are to be fed complete Cheng Hou starts circulation shear pump and carries out comprehensive strong cyclic shearing to the material in reaction kettle, makes various objects while stirring Material fully effect coupling is complete, reacts 1-2h, system temperature is down to 40-60 DEG C, and composite air compressor oil combination is made Object III.
5 comparative example of embodiment
Equipment and operation are with embodiment 4, the difference is that thiocarbamate is replaced extreme-pressure anti-wear micro mist, other raw materials And its dosage is constant, obtains composite air compressor oil composition IV.
6 comparative example of embodiment
Equipment and operation with embodiment 4, unlike polyethers family macromolecule replaced into anti-emulsifying compound drug, other raw materials and Its dosage is constant, obtains composite air compressor oil composition V.
Two, the composite air compressor oil composition that the various embodiments described above are prepared is tested for the property ratio respectively Compared with：
The performance test results of 2 each composite air compressor oil composition of table compare
From the data of upper table as it can be seen that the present invention composite air compressor oil composition have excellent viscosity temperature characteristic, Oxidation Stability and high temperature performance.Composition IV is compared with composition III, and maximum stings load PBThere are apparent reduction, table The extreme pressure property of the composition III of bright addition extreme-pressure anti-wear micro mist is more excellent than composition IV, abrasion resistance more preferably, and group Composition IV will be far smaller than by closing the wear scar diameter of object III, illustrate that the lubricant effect of composition III is also more preferable；Composition III and Composition V is compared, and demulsibility has greatly improved, and is added to the composition III of anti-emulsifying compound drug, is reduced grease Contact area reduces oil water interfacial tension, and water is easy to separate from oil, shortens the demulsification time.
The composite air compressor oil composition of the present invention has excellent antiwear and antifriction and greasy property, makes engine Vibration reduces, and operates steadily, lower noise, saves power consumption 2-5%；High temperature with brilliance and thermal oxidation stability energy, Low carbon distribution tendency and low volatility, significantly extend the compressor drain period, the drain period is than common mineral oil type compressor oil Extend 3-6 times；With outstanding heat conductivility, high 5-7% of thermal conductivity ratio mineral compressor oil or so has good anti- Rotten rustless property prevents the abrasion and corrosion of each component of compressor, reduces the replacement of filter and gs-oil separator, reduces machinery The replacement number of part such as piston ring, bearing and sealing element extends pressure to reduce service material expense and labour cost spending 2-3 times of contracting machine service life.
Finally it is to be appreciated that foregoing description is merely a preferred embodiment of the present invention, those skilled in the art is in the present invention Enlightenment under, without prejudice to the purpose of the present invention and the claims, can make and indicate as multiple types, such change It changes and each falls within protection scope of the present invention.
