The invention discloses a preparation method for high-
lubricity super
essential oil. The method comprises the following steps: A, adding
isopropyl isostearate A, polyether ester B and hydrotreated
base oil to a reaction kettle; B, heating to 60 DEG C and stirring in a
machine and
pulse mode; C, adding an
antioxidant and a
corrosion inhibitor to a stirring device; and D, filtering. The preparationmethod is capable of using narrow
distillation range, high
flash point, and repeatedly hydrotreated
base oil in the different viscosities as the
base oil, abandoning traditional environment-unfriendlyextreme pressure additives, such as sulphur,
phosphorus and
chlorine, performing the synthetic
polymerization through autonomously developed different vegetable fat, and enabling different syntheticpolymerization esters to be compounded so as to achieve the performance of the sulphur, the
phosphorus and the
chlorine. In addition, the high-
lubricity super
essential oil is non-toxic, odorless, andno
simulation to a
human body, and a product after a
polymerization reaction is capable of solving defects that traditional used
stanol ester is easily oxidized and tacky, the cost is lower in the follow-up
environmental protection treatment, an
environmental protection pressure is reduced, and the product reaches or exceeds the performance of imported similar products.
