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 paint, in particular to an oil-resistant electrostatic conductive paint. (2) Background technology [0002] Existing static conductive and corrosion resistant coatings not only have high production costs, but are not stable in terms of static conductive performance, corrosion resistance, and film forming time, and are complicated in construction. (3) Contents of the invention [0003] The purpose of the present invention is to provide a zinc-rich silicate, oil-resistant and static conductive paint with low production cost, stable static conductive performance, stable oil resistance, fast drying, firm coating film, simple construction, and stable film forming time. [0004] The zinc-rich silicate, oil-resistant and electrostatic conductive paint of the present invention is produced by the following methods: (1) mixing ethyl orthosilicate and absolute ethanol, stirring, and carrying...
