Abstract

An antistatic oil-resistant epoxy resin is prepared through mixing epoxy resin E42, meta-xylene phenolic rsin, organosilicon resin, dibutyl o-benzoate and ethyl n-silicate, adding Si-alloy powder, stirring, adding absolute alcohol or ethanediamine, and stirring. Its advantages are high electrostatic conductivity and oil resistance, low cost and firm film.

Description

(1) Technical field [0001] The invention relates to a coating, in particular to a static-conducting and oil-resistant coating. (2) Background technology [0002] The existing anti-static and anti-corrosion paint not only has high production cost, but also has unstable anti-static performance and anti-corrosion performance, and complicated construction. (3) Contents of the invention [0003] The purpose of the present invention is to provide an epoxy conductive and oil-resistant epoxy paint with low production cost, stable static conductive performance, stable oil resistance, fast drying, firm coating film and simple construction. [0004] The epoxy electrostatic conductive oil-resistant coating of the present invention is produced by the following method: E42 epoxy resin, m-xylenol aldehyde resin, organic silicon resin, dibutyl phthalate, orthosilicate are mixed and stirred evenly, and silicon alloy is added powder, stir eve...
