The aim of the project is to develop a new eco-friendly polymeric material with fire-retardancy properties using bio-based materials and phosphorous-based flame-retardant systems that will not drastically affect the matrix properties.
The ubiquity and widespread use of polymeric materials in all aspects of modern life carries an inherent fire risk due to large fire load and high flammability of hydrocarbon-based materials. Furthermore, the materials tend to become lighter and ¿bio-based¿ in order to achieve the perfect renewability of resources. Nowadays, due to specific mechanical properties (stiffness and strength), low weight and corrosion resistance, the consumption of fibre reinforced plastics is experiencing a continuous increase in a wide range of applications and sectors. Within this class of materials, the natural fibres, such as flax, jute, kenaf etc. are often used with a view to decrease their environmental impact. These materials, known as biocomposites. will involve more and more the organic matter. In order to modify, reduce, delay or even stop the combustion process of polymeric materials, the research of suitable flame retardant is crucial in safeguarding against accidental fires, costly damage to material goods, and in ensuring the health and safety of the people. Halogenated flame retardants additives were widely applied in the past because of their low impact in other material properties and the low loading levels for firefighting; however, potentially dangerous effects on human health and environment raise concerns about their risk-benefit balance. In this contest, new safer phosphorus-based flame retardants will be synthetized and developed starting by different bio-derived platforms (such as organic acid and polymers). Chemical (FTIR), thermal (TGA; DSC), morphological (SEM), mechanical (tensile, flexural and impact) and fire properties (LOI and Cone Calorimeter test) of flame retarded polymers/biocomposites will be assessed and optimized.
