NOVELTY - A metal oxide precursor of antistatic flame-retardant polyester resin is prepared by chelating graphene oxide with 10-30% carboxylation proportion and metal oxide precursor with synergistic catalysis and inflaming retarding effect to obtain material A; heating material A to obtain material B; and carrying out in-situ polymerization on material B and alkyl phosphonic acid metal salt to obtain antistatic flame-retardant polyester resin. USE - Preparation of metal oxide precursor of antistatic flame-retardant polyester resin for preparing antistatic flame-retardant polyester fiber (claimed). ADVANTAGE - Static resistance is achieved by reducing graphene oxide in situ by utilizing heat and reducing atmosphere in the polymerization process.
