PDMAS/Titanium dioxide epoxy hybrid nanocomposite coating for steel petroleum tanker trucks
Nanocomposite coatings play a strategic role in the treatment of metal surfaces in the petroleum sector, especially steel oil transportation trucks, by providing novel materials exhibiting superior stability to various severe conditions.
To confirm this concept, TiO2 nanoparticles (TNPs) were fabricated by a simple sol-gel method and blended with poly-dimethylamino siloxane (PDMAS) to fabricate PDMAS/TiO2 nanocomposite acting as a multifunctional modifier for polyamine-cured epoxy coating. The anti-corrosion performance of surface-modified PDMAS/TiO2 epoxy coated films versus unmodified conventional epoxy was investigated by salt spray accelerated corrosion test.
The mechanical resistance characteristics of the coatings were studied by adhesion, abrasion and bend coating strategies. The chemical durability was checked by water and solvent immersion tests. Finally, UV resistance test was performed to show the effect of fluorescent UV radiation on the checked epoxy coated films.
The obtained results illustrated the superior anti-corrosion, mechanical, chemical, electrical, thermal and UV resistance characteristics of the PDMAS/TiO2 epoxy hybrid nanocomposite coating.
