Thermal Behavior of Epoxy Resins Containing Manganese Compounds

Abstract:

A novel cheap macromolecular intumescent flame retardants (Mn-MIFR), was synthesized. Epoxy resins (EP) were modified with Mn-MIFR to get the flame retardant EP, whose flammability and burning behavior were characterized by UL 94, limiting oxygen index (LOI), dilatation, char yield, smoke density rating (SDR) and maximum smoke density (MSD). The epoxy resins were obtained for the UL 94 V-0 rating at low Mn contents of 4.0 % get a LOI of 26.5% and char yield of 18.2%. Dilatation, SDR and MSD of EP/Mn-MIFR decreased. The degradation behavior of the EP/Mn-MIFR was studied by TG and EDX analysis. The experimental results exhibited that the initial decomposition temperature (IDT) was decreased, integral procedure decomposition temperature (IPDT) and amounts of Mn and P at the residue were increased.
