Self-crosslinking acrylic latexes containing nanoparticles ZnO with increased corrosion and chemical resistance of coatings

Popis výsledku v původním jazyce

The requirements put on coating materials are more and more stringent mainly in the environmental domain, especially as regards VOC emissions. This is why water-based binders as alternatives to solvent-based binders, to provide paints possessing equally good use properties, are intensively sought. The objective of this work was to assess the anticorrosion and chemical properties of paint films based on new self-crosslinking acrylate aqueous dispersions. The dispersions were synthesized via two-step emulsion polymerisation to obtain a core-shell system. Nanostructural ZnO in an amount of 1.5% (w/w) was added to the system during the latex binder synthesis. Paints with an enhanced corrosion resistance and chemical resistance of the films were prepared. The dispersions prepared were pigmented with anticorrosion pigments and their properties were compared to those of commercial water-based dispersions with either identical or different paint film formation mechanisms. The results gave evidence that if a well-selected pigment is used, the binders can be used to obtain anticorrosion coating materials for metallic substrates.
