AI Technical Summary
Traditional electromagnetic shielding coatings have problems with aging resistance and corrosion resistance. Metal fillers are prone to corrosion and organic polymers are prone to molecular chain degradation, which leads to the degradation of coating performance and shortened service life.
Based on graphene oxide, combined with corrosion resistant agents and hindered phenolic functional additives, an anti-electromagnetic shielding stealth coating is prepared through a specific chemical reaction. The coating uses graphene oxide, waterborne epoxy resin, conductive filler, infrared transparent filler, film-forming aid, leveling agent, defoamer, corrosion resistant agent, hindered phenolic functional additives, and curing agent to form a corrosion-resistant barrier and ultraviolet aging protection network with a four-armed star-shaped molecular structure.
It achieves low infrared emissivity, excellent shielding performance, anti-aging performance, corrosion resistance and impact resistance, thereby improving the stability and service life of the coating.
