Problems solved by technology

But the graphene mentioned is single-layer graphene powder, the fewer graphene layers in production, the more expensive the price, the price of single-layer graphene is extremely expensive, and the output is extremely low, which cannot meet the requirements of mass production of coatings; at the same time, the Conductive powder coatings also add surface-treated functional conductive barium sulfate, conductive carbon black or conductive titanium dioxide, which greatly increases the cost compared to ordinary fillers

Description

technical field [0001] The invention relates to a conductive powder paint and a preparation method thereof, in particular to a conductive powder paint filled with graphene powder. Background technique [0002] As an environmentally friendly and efficient coating, powder coatings are widely used in automobiles, home appliances, construction, petrochemical and other fields. In some applications, powder coatings are required to provide static or conductive capabilities, which are usually achieved by incorporating conductive fillers to prepare conductive powder coatings. Traditional conductive fillers include metal powders (gold, silver, nickel, zinc, aluminum, etc.), metal oxides (zinc oxide, antimony oxide, tin oxide, etc.) and non-metallic powders (graphite, carbon black, etc.). Metal powders and their oxides have good electrical conductivity but are expensive; graphite and carbon black are cheap, but their dosage is large, which will lead to a decrease in the mechanical pro...
