The invention belongs to the technical field of air compressor oil, and particularly discloses an air compressor oil composition and a preparation method thereof. The air compressor oil composition isprepared from the following raw materials in parts by weight: 25-35 parts of base oil, 1-3 parts of graphene, 3-5 parts zinc oxide nanoparticles, 10-15 parts of alkyl naphthalene, 0.1-1 part of a detergent, 0.1-1 part of a pour point depressant, 0.1-1 part of a demulsifier, 0.1-2.2 parts of a sulfo-phenolic ester antioxidant, 0.1-1.1 parts of an anti-rust agent, 0.1-5 parts of an anti-wear reagent at extreme pressure and 0.1-1 part of an anti-foaming agent; alkyl naphthalene is placed into the base oil and mixed and stirred for 30-40 minutes, then a mixture is placed in a vacuum reactor, vacuuming is performed, the temperature is controlled at 60-70 DEG C for 3-4 h to obtain mixed oil A. The design is ingenious, the composition is reasonable and the method is simple, and the obtained aircompressor oil is high in
