Flame Retardant Epoxy Resins Containing Bisaryl Diphosphates Oligomer

Article Preview

Abstract:

Bisphenol A bis( diphenyl phosphate) oligomer (BDP) as flame retardants (FR) was synthesized, whose structure was characterized by IR. 30% weight BDP was doped into epoxy resins (EP) to get 26.2 % of LOI and UL 94 V-0. The degradation behavior of EP containing BDP was studied by TG, SEM and cone calorimeter. In the thermal degradation of EP containing BDP, the initial decomposition temperature, Tm and heat release and smoke production are decreased while Rmax, char yields, and inherent thermal stability are increased. Surface of the char is dense and compact, which can isolate the transfer of mass and heat between the materials and the flame to protect the unburned materials.
