preparation example Construction

[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...

Abstract

The invention provides a spindle oil composition. The spindle oil composition comprises 43.45-56wt% of aromatic ester oil, 37.45-50wt% of poly(alpha-olefin), 0.1-3wt% of an anti-oxidant, 0.01-0.5wt% of a metal deactivator, 0.1-3wt% of a corrosion inhibitor and 0.0005-0.05wt% of an anti-foaming agent. Compared with the prior art, a preparation method of the spindle oil composition is free of naphthenic mineral oil or alkylbenzene base oil having an unstable source, utilizes poly(alpha-olefin) and aromatic ester oil as base oil of the spindle oil composition. The poly(alpha-olefin) and aromatic ester oil have wide sources, simple synthesis routes and high yields and thus the poly(alpha-olefin) and aromatic ester oil as spindle oil composition preparation raw materials can be supplied stably.

Description

technical field [0001] The invention relates to the technical field of spindle oil, in particular to a spindle oil composition. Background technique [0002] Spindle oil, also called spindle oil, is a low-viscosity spindle bearing oil, made of highly refined base mineral oil, and added to detergents, dispersants, anti-wear agents, antioxidants, anti-corrosion agents, anti-foaming agents and other additives One or more refined. Spindle oil has good viscosity-temperature properties; good lubricity and anti-wear properties; good anti-oxidation properties; it can prolong the life of the spindle and bearings. Spindle oil is mainly used for textile machines, worsted spindles, spindles of automatic machine tools, light-load hydraulic circulation systems, light-load high-speed industrial textile bearings, industrial circulation systems, etc. [0003] According to the different types of base oil, spindle oil is mainly divided into mineral type spindle oil and synthetic type spindle...
