Method and process of steel structure arc spraying composite corrosion proof coating system

Abstract

The invention provides a method and a process for spraying a composite anticorrosive coating system by electric arc for a steel structure, which belong to the method and the process for anticorrosion of the steel structure. In the anticorrosive coating system, first, rust removal and coarsing are carried out on the surface of the steel structure; then, an anode metal coating is sprayed by electric arc; then, a nanometer modified epoxy seal paint as a primer coating, an MIO epoxy paint or nanometer modified MIO epoxy paint as an intermediate paint coating, and a nanometer modified fluorine-containing polyurethane paint or fluorine-containing polysiloxane paint or siloxane modified acrylic polyurethane as a finishing coating are coated on the metal coating in sequence. The composite anticorrosive coating system has excellent performances of corrosion resistance, weather resistance, stain resistance, chemical product resistance, decoration and the like, and can obviously reduce or remit anticorrosive maintenance work and cost of the steel structure in late stage.

AI Technical Summary

Benefits of technology

In this patented technology, there were developed two types of antirust paints that could be applied on steel surfaces without causing any harm during construction processes. One was made up of aluminum flakes mixed with epoxy resin binder while another one consisted mainly of nanoparticles modified into hydrophobicity. Both these materials improved their durability against sea water and atmospheric pollution compared to traditional methods like electroplated nickel plates. They have been shown effective at preventing rust formation even after being exposed over many months' service life. Additionally, they provide enhanced physical separation between different layers when painted onto steel, resulting in longer lifespan under harsh environments such as marine coastline areas. Overall, both technical effectives include providing long lasting and efficient solutions towards creation of strong yet resistant environmentalally friendly products suitable for architectural purposes.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the durability and lifespan of protective layers applied over steels due to environmental factors like saltwater environments caused by sea water intrusion during transportations from coastline areas through long distances without having any cracks formed under these conditions.
