Development of Anti-Aging and Anticorrosive Nanoceria Dispersed Alkyd Coating for Decorative and Industrial Purposes

Abstract

This study focuses on nano cerium oxide particles as alternative additives in solvent-based alkyd coatings in order to improve anticorrosive and anti-aging properties. The paint samples were formulated with cerium oxide micro and nanoparticles, and the coating quality characteristics were compared with coating formulated with commercial anticorrosive and UV-aging agents. Formulations were prepared with 3 wt % commercial anticorrosive agent as reference material (RP), 3 wt % cerium oxide microparticles (CER1), 3 wt % and 1% cerium oxide nanoparticles (CER2 and CER3), respectively. The basket milling technique with zirconium balls was used for the preparations of coatings and characterizations were performed by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and contact angle measurements. Improvement in the anticorrosive properties was proven with electrochemical impedance spectroscopy (EIS) and accelerated salt spray tests based on ISO 4628 Evaluation of Degradation of Coatings. Furthermore, physical and mechanical tests were run according to standard test methods for coatings and reported. Results showed that cerium oxide particles provide anticorrosive, UV defender, and self-cleaning effects, besides excellent physical resistance to alkyd coatings. The impact of cerium oxide nanoparticles was found to be stronger than those of the microparticles.

Coating Properties of Alkyd Resin, Epoxy Resins and Polyurethane Based Nanocomposites: A Review

“…Another research concentrated on particles of nano cerium oxide as substitute additives in solvent-based alkyd coatings to enhance anti-anti-ageing and corrosive characteristics (Kızılkonca and Erim, 2019). The authors developed the paint samples with micro and nanoparticles of cerium oxide and thereafter, compared the coating quality properties with coating formulated with commercial UV-aging and anticorrosive agents.…”

Efficient Photocatalytic Degradation of Methylene Blue Dye from Aqueous Solution with Cerium Oxide Nanoparticles and Graphene Oxide-Doped Polyacrylamide

“…The oxidation state transition between Ce 3+ and Ce 4+ found on the surface of CeO 2 -NPs is responsible for the catalytic activity of this nanoparticle. Although the toxicity of nanoparticles is still a questionable issue, it has been shown by experiments that CeO 2 -NPs are not toxic, and these nanoparticles are compatible with hydrogels and impart durability and antibacterial properties to wound-healing hydrogels and anticorrosive properties to paints. − In addition, it has been shown that CeO 2 nanoparticles synthesized by the green method gain additional and different surface properties. , The effective use of CeO 2 -NPs obtained by the green method in dye photodegradation has been lately demonstrated …”

Effect of Graphene Oxide on UV-Thermo-Humidity Degradation of Environmentally Friendly Alkyd Composite Coating

“…Degradation of polymers in general or paint coating in particular under high temperature, oxygen, sunlight, UV radiations, and humidity leads to losing adhesion, blistering or peeling [1][2][3][4][5]. Jianwen Hu et al [6] showed the degradation of acrylic polyurethane varnish coating under fluorescent UV/condensation and xenon lamp exposure.…”
