초록
Epoxy resin is widely used as aerospace, automobile, construction and electronics dueto their good mechanical and electrical properties and environmental advantages. However, theinherent flammability of epoxy resin has limited its application in some field where good flameretardancy is required. Nano clay can enhance the properties of polymers such as flames retardancyand thermal stability. In this study, we have investigated the nanoclay filled epoxy composite,which has good flame retardancy while maintaining high mechanical properties. The curedepoxy resins were obtained using an electron beam curing process. The nano clays were dispersedin epoxy acrylate solution and mechanically stirred. The prepared mixtures were irradiated usingan electron beam accelerator. The composites were characterized by gel content and thermal/mechanical properties. Moreover, the flammability of the composite was evaluated by limitedoxygen index (LOI). The flame retardancy of nano clay filled epoxy composite was evidentlyimproved.
