Riassunto (Inglese)
This thesis investigates the curing behaviour of carbon black model paints prepared with four linseed oil binders: an untreated cold-pressed oil, a pre-oxidised sun-thickened oil, a thermally polymerised heat-bodied oil and a lead-treated dark-drying oil. The aim is to understand how different oil pre-treatments affect the time-resolved evolution of the paint matrix. Pure oils were analysed by TGA, HPLC-qTOF-MS and EGA-MS to define their lipid composition, oxidative reactivity and thermal stability. The corresponding model paints were then studied during ageing using gravimetric oxygen uptake measurements, SPME-GC-MS, EGA-MS and SS-NMR. The results show that the pre-treatments strongly modify the initial state of the binder, influencing oxidative reactivity, volatile product formation and the structural development of the paint film.
