NOVELTY - Synthetic refrigerating machine oil comprises 10-50 wt.% naphthenic base oil, 48-88 wt.% alkylbenzene oil, 1.5-2.5 wt.% additive, and antifoaming agent. USE - Used as synthetic refrigerating machine oil. ADVANTAGE - The refrigerating machine oil has suitable viscosity, excellent low temperature performance, hydrolytic stability and solubility, good compatibility with mineral oil and ester oil. The method is simple, energy saving, and easy for industrialized production; has high efficiency; adopts pulse modulation processing technology, and adopts naphthenic base oil with excellent low temperature performance and good solubility; and can be widely used. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for method for preparing synthetic refrigerating machine oil comprising (S1) adding 99% alkylbenzene base oil synthesized by alkylation of high-purity alpha olefins and aromatic hydrocarbons and 1 wt.% additives into the pulse pneumatic blending system, initially mixing at room temperature, and performing pulse blending treatment for 10-20 minutes to obtain alkylbenzene oil, (S2) providing 10-50% of naphthenic base oil, 48-88% of alkylbenzene oil, 1.5-2.5% of additives, and defoamer (balance), (S3) adding the naphthenic base oil, alkylbenzene oil, additives and antifoaming agent to the blending kettle in sequence, and initially mixing at room temperature, and performing pulse blending treatment for 20-40ing minutes, (S4) taking a sample and test, qualifying the test, passing high-purity nitrogen from the bottom of the reconciliation kettle for aeration treatment for 1-1.5 hours, and (S5) taking samples for trace moisture detection, and qualifying the detection, and filling into a high-clean packaging barrel.
