Evaluation of the Efficiency of Protection Against Static Electricity when Using Nanomodified Paint Coatings

This article deals with the protection of agro-industrial complex objects from static electricity by nanomodified coatings. It is indicated that one of the main causes of ignition of objects of the agro-industrial complex is static electricity discharges, leading to damage to equipment, possible fires, explosions and injuries to maintenance personnel. The conducted experimental studies of modified coatings with carbon nanotubes are reflected. With a concentration of compositions with carbon nanotubes in the paintwork material up to 0.1%, the resulting coating becomes up to two times more antistatic and has increased adhesive strength (adhesion strength increases two or more times). When analyzing the samples on a scanning electron microscope, it was determined that the introduction of carbon nanotubes into the composition of paint and varnish materials contributes to a faster (1.2–1.5 times) passage of electrons through the coating and, as a result, the formation of dark areas in electronic images, which characterizes conductive and antistatic coating quality. The use of acrylic paints and varnishes modified with carbon nanotubes will reduce the risk of ignition of fire hazardous objects of the agro-industrial complex, as well as extend the service life of protective coatings.
