Epoxy resins have been widely used as coatings, adhesives, and structural composites as well as electronic materials due to their superior mechanical properties, excellent thermal resistance and good process ability; diglycidyl ather of bisphenol A (BGEBA), comes from a fossil based materials, which presents the most common of the epoxy precursors in the world. Due to the limitation on environmental issue, fossil based materials should be replaced by bio-based one. Additionally, the low flame-retardancy of epoxy resin limits its use in may fields; there are many research groups effort to introduce flame resistance epoxy based polymer. In this work, levulinic acid was used as renewable resource to prepare and epoxy monomer and flame retardant reactivity. The new flame retarding epoxy resin was synthesized via 5-steps reaction. The resulted epoxy was cured with commercial curing agent isophorondiamine (IPDA) and some basic properties of final polymer were characterized. |
