Research Progress on Bio-based Halogen-free Flame Retardant Epoxy Resin
With the increasing global energy crisis and environmental pollution,the design and synthesis of bio-based flame retardants and epoxy monomers using biomass raw materials for flame retardant modification of epoxy resin have attracted widespread attention.This paper provides an overview of the research progress including additive,reactive and intrinsic flame retardant epoxy resins based on biomass.The synthesis of bio-based flame retardants and flame retardant epoxy monomers are described,and the performance and flame retardant mechanism of bio-based flame retardant epoxy resin using three flame retardant modes are analyzed.Furthermore,the development trend of bio-based flame retardant epoxy resin is prospected.
