Abstract

An antistatic paint is prepared through mixing ethyl n-silicate with absolute alcohol, stirring, alcoholysis reaction, dropping hydrochloric acid diluted by purified water to make pH=2-3, laying aside, adding organic silanamine, stirring, adding zinc powder and stirring. Its advantages are high electrostatic conductivity and corrosion resistance, low cost, fast dry, and high firmness of film.

Description

(1) Technical field [0001] The invention relates to a coating, in particular to an oil-resistant and static-conductive 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 properties, anti-corrosion properties and film-forming time, and complicated construction. (3) Contents of the invention [0003] The purpose of the present invention is to provide a zinc-rich silicic acid oil-resistant and static-conductive coating with low production cost, stable static-conductive performance, stable oil-resistant performance, fast drying, firm coating film, simple construction and stable film-forming time. [0004] Zinc-rich silicic acid oil-resistant and static-conductive paint of the present invention is produced by the following method: [0005] (1) Ethyl orthosilicate and dehydrated alcohol are mixed, stirred, and alcoholysi...
