Preparation and Properties and Application of Renewable Source (Palm Oil Polyol) Based Polyurethanes Coatings and its Thermal Stability Improvement by Clay Nanocomposites

Abstract:

A thermal study (using TGA) was carried out on polyurethane (PU) paint modified with layered silicate (organoclay) nanocomposites. The result showed that by adding clay, the PU paint/organoclaynanocomposites demonstrated better thermal stability than the virgin polyurethanepaint. The PU paint was synthesized with polyol prepared from palm oil i.e. a renewable resource.Whilst polyurethane modified with layered silicate (organoclay) nanocomposite is considered a new class of material. A tremendous improvement of the nanocompositecompared to pure polymers, although the filler content is just 2-5 wt%.The unmodified layered silicate (kunipia-F) was treated with cetyltrimethyl ammonium bromide (CTAB-mont) and octadodecylamine (ODA-mont) were used as swelling agents to treat Na⁺-montmorillonite and forming organoclay through ion exchange.The morphology of the nanocomposites was characterized by X-ray diffraction (X-RD) and transmission electron microscopic (TEM) and the pattern showed that all of the nanocomposites produced from this work are intercalated type.
