This invention pertains to the field of insulating and anticorrosive powder coating technology and discloses a preparation method for insulating and anticorrosive powder coating.
The invention involves mixing phenolic modified epoxy resin bisphenol A epoxy resin, polyurethane insulating and anticorrosive agent, dicyandiamide imidazole accelerator, epoxy acetyl propyl phenol, mica powder, methacrylate leveling agent, pure benzoin defoamer, and pigment uniformly, stirring, and then adding them to a twin-screw extruder for extrusion and tablet pressing.
The powder is then crushed by a high-speed crusher, sieved through a mesh, and finally, the insulating and anticorrosive powder coating is obtained.
This invention forms a dense coating film on the substrate through the anticorrosive coating, isolating the corrosive medium from the metal substrate.
The coating is insulating and free of electric leakage, ensuring better corrosion resistance for the substrate.
