Abstract

The invention belongs to the technical field of PAO synthetic oils, and especially discloses a PAO synthetic oil and a preparation method thereof. The PAO synthetic oil comprises, by weight, 25-35 parts of polyalphaolefin PAO5, 5-8 parts of polyalphaolefin PAO30, 1-3 parts of graphene, 3-5 parts of zinc oxide nanoparticles, 10-15 parts of alkylnaphthalene, 0.1-1 part of a detergent, 0.1-2 parts ofa sulfur- or phosphorus-containing extreme pressure anti-wear agent, 0.1-1 part of a pour point depressant, 0.1-1 part of a demulsifier, 0.1-2.2 parts of a thiophenolate type antioxidant, 0.1-1.1 parts of a rust inhibitor, 0.1-5 parts of an extreme pressure anti-wear agent and 0.1-1 part of an antifoaming agent. The method has the advantages of ingenious design, reasonable composition and simplicity, and the obtained PAO synthetic oil has a high lubrication degree and a long service life, and is suitable for being promoted and used.

Description

technical field [0001] The invention relates to the technical field of PAO synthetic oil, in particular to a PAO synthetic oil and a preparation method thereof. Background technique [0002] At present, the air compressor oil in our country is still dominated by mineral oil, accounting for more than 80%. Mineral compressor oil is a blend of oil after a series of fractionation, purification, refining, and additives; due to its extremely low biodegradability , so it is difficult to decompose in nature, causing increasingly serious pollution to the natural environment. With the development of industrial technology, the use of mineral oil in air compressors has increasingly exposed serious shortcomings, mainly manifested in: short service life, serious environmental pollution (noise, exhaust, waste oil discharge), high energy consumption, frequent oil changes And failures seriously affect the efficiency of some production, especially those highly automated production.
