preparation example Construction
[0051] The application also provides a kind of preparation method of described screw air compressor oil, comprising:
[0052] The raw materials are mixed, stirred uniformly, and then subjected to variable temperature treatment to obtain the screw air compressor oil.
[0053] Preferably, the stirring adopts a double planetary mixer to carry out according to the following procedures:
[0054] In the first stage, the revolution speed is 5-10r / min, the rotation speed is 100-500r / min, and the time is 10-30min;
[0055] In the second stage, the revolution speed is 50-100r / min, the rotation speed is 2000-3000r / min, and the time is 30-60min;
[0056] In the third stage, the revolution speed is 10-20r / min, and the rotation is stopped, and the time is 40-70min.
[0057] By controlling the stirring speed, the stability and service life of screw air compressor oil can be improved.
[0058] Optionally, the revolution speed of the first stage can be any value between 5r / min, 6r / min, 7r / m...
Embodiment 1
[0071] A screw air compressor oil, the raw materials of which are calculated in parts by weight, including: 40 parts of base oil, 5 parts of octylbutyldiphenylamine, 1 part of 2,6-di-tert-butylphenol, dipropylene glycol diphenylbenzene 14 parts of acid ester, 20 parts of oil-soluble polyether and 20 parts of xylitol and sorbitol; The base oil per 100 parts by weight includes 30 parts of 220N base oil, 10 parts of 300N base oil and 60 parts of 250N base oil.
[0072] Under the condition of 20KHz, the raw materials were ultrasonically treated for 10min, and after mixing, they were stirred evenly with a double planetary mixer, and left to stand for 12h, then the system was heated to 60°C at a uniform speed of 1°C / min, and then cooled to 20°C within 1min, and then Heating to 50°C at a constant speed of 2°C / min, and naturally cooling to room temperature to obtain screw air compressor oil. Stirring is carried out according to the following procedures: the first stage revolution spee...
