AI Technical Summary
Existing anti-corrosion coating materials have shortcomings in terms of high strength, flame retardancy and corrosion resistance. Traditional flame retardants affect mechanical properties, lead- and chromate corrosion inhibitors are toxic and not environmentally friendly, and tannic acid is unevenly dispersed and easily lost.
A functional composite preparation method was used to fix tannic acid and borax on halloysite nanotubes to form TA-B@HNTs functional composites, which were then mixed with polyetheramine and isocyanate and mixed by high-pressure impact to form a protective coating.
It achieves a synergistic improvement in the coating's high strength, flame retardancy, and corrosion resistance, solving the bottleneck of traditional materials in performance balance and providing efficient flame retardant and corrosion-resistant functions.
