▎ 摘　　要

NOVELTY - Preparing graphene super-strong flame-retardant fibre involves preparing graphene mixed functional master batch, drying the master batch obtained and the common polyethylene terephthalate material, mixing, melting and spinning, cooling and moulding, drafting, obtaining functional fibre, preparing graphene suspension, coating the graphene suspension obtained on the functional fibre surface obtained, drying to obtain the graphene super-strong flame retardant fibre. USE - Method for preparing graphene super-strong flame-retardant fibre. ADVANTAGE - The method enables to prepare graphene super-strong flame-retardant fibre with high strength, good flame retardant property, high temperature without melting.
