The present invention relates to a flame-retardant expanded rubber and a method of manufacturing the same. The flame retardant expansion rubber comprises 15 to 34% by weight of the base resin, 53 to 70% by weight of the inorganic flame retardant, 5 to 10% by weight of the expansion agent, 2.5 to 4.5% by weight of the blending oil, and 0.1 to 2% by weight of the crosslinking agent. Ethylene Vinyl Acetate (EVA), Ethylene Methyl Acrylate (EMA), Ethylene Propylene Terpolymer (EPT), Ethylene-Propylene-Diene- Methylene, EPDM), propylene oxide (PO), polyethylene (polyethylene, PE) and one or more selected from the group consisting of ethylene-based copolymers, the expanding agent is graphite, borax, vermiculite, perlite, azodicarbonamide , Azodiaminobenzene, dinitroso, dimethyl terephthalamide, benzenesulfonylhydrazide, oxybisbenzenesulfonylhydrazide and the like selected from the group consisting of It is the phase. |
