Problems solved by technology

[0005] At present, the practical light-colored conductive powder coatings on the market are all made of conductive fibers. The problem with conductive powder coatings is that the resistivity is extremely unstable, some of which are around 100 ohms, and some of which can reach more than 1000 ohms. , this feature makes it difficult for the existing light-colored conductive powder coatings to further develop the market

Abstract

The invention relates to a conductive powder coating and belongs to the technical field of powder coatings. The conductive powder coating is prepared from, by weight percentage, resin, a curing agent, titanium dioxide, zinc oxide powder, conductive carbon black, a defoaming agent and a crosslinking agent. The powder coating is good in conductive performance.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a conductive powder coating. Background technique [0002] Powder coatings started in the late 1930s. The earliest prototype was to spray polyethylene powder onto metal surfaces in a molten state by flame spraying. [0003] Conductive powder coating is a composite polymer conductive material. After electrostatic spraying and high-temperature curing, downstream customers can obtain polymer protective conductive coatings, which are used in fields such as eliminating static electricity, electromagnetic shielding, electric heating, and anti-corrosion; the earliest conductive Powder coating can be traced back to 1948, when the United States published a patent for making conductive adhesive from silver and epoxy resin. [0004] The existing conductive powder coatings are mostly made of dark conductors such as carbon black, which has the advantages of obvious conductive effect,...
