Flame-retardant performance of phosphorylated furan-containing alkyd resins

Résumé

Over the past decade, with the emergence of environmental and human health concerns, research has focused on developing new solutions to replace fossil resources with more sustainable biobased resources. Furan derivatives can be obtained from plants and their structures provide high resistance to high temperatures. Therefore, these furan derivatives have been functionalized with phosphorus to increase their fire resistance properties. Thus, a new biobased bisfuran containing nitrogen and phosphorus (HMF-MXDA-DEP) was synthesized and used for the first time in polymerization to develop alkyd resins. The flame retardant properties of these resins have been studied. These alkyd resins are generally used as a binder in paint or varnish formulations. The use of a reactive flame retardant during the polycondensation reaction of alkyd resins makes it possible to form covalent bonds and offer better durability over time. The impact of HMF-MXDA-DEP on film properties such as drying time, flexibility, adhesion and color was studied and the thermal and flame retardant properties by differential scanning calorimeter, thermogravimetric analysis and calorimeter pyrolysis-combustion fluxes were evaluated. Increased thermal stability and good flame retardant (FR) properties of alkyd resins have been demonstrated. In the cone calorimeter test, the lowest peak in heat release rate (pHRR) was obtained with a 2 wt % coating of P HMF-MXDA-DEP on wood and a 49 % decrease in pHRR compared to FR-free alkyd resins has been demonstrated.
