[0035] The present invention has no special limitation on the source of the poly-alpha-olefin, just use the poly-alpha-olefin well-known to those skilled in the art, such as the commercially available poly-alpha-olefin that can be used, also can adopt the well-known polyalpha-olefin of those skilled in the art The technical scheme for preparing poly-alpha-olefins is self-prepared. In the present invention, the synthesis route of the poly-α-olefin is simple, and the synthesis conditions are mild; the preparation method of the poly-α-olefin may include the following steps: polymerizing and hydrogenating the α-olefin to obtain poly-α-olefin; α-olefins can be obtained by ethylene oligomerization or paraffin cracking.
[0036] The spindle oil composition provided by the present invention includes 0.1wt%-3wt% of antioxidant, preferably 0.2wt%-2.5wt%, more preferably 0.3wt%-2wt%. In the present invention, the antioxidant preferably includes one or more of organic phenols, amine comp...
