Oil-soluble conductive additive and preparation method therefor

Abstract

An oil-soluble conductive agent and a preparation method therefor. Raw materials for preparing the oil-soluble conductive agent comprise the following components: 20 parts by weight of ethyl caprate or bis(2-ethylhexyl) sebacate, 1.8-2.2 parts by weight of ethyl methyl carbonate, and 2-8 parts by weight of fluorine-containing ion salt; and the fluorine-containing ion salt is selected from one or more of lithium bis(trifluoromethanesulfonyl)imide, lithium trifluoromethanesulfonate, and lithium tetrafluoroborate. The oil-soluble conductive agent is apparently a colorless transparent liquid at 25° C. or higher, and the conductivity at 25° C. reaches 1×10−4 S/cm. The oil-soluble conductive agent can be completely dissolved in a base oil and improve the conductivity thereof, so as to have the effects of arc suppression, being anti-static, cooling, heat transfer, and conduction.
