▎ 摘  要

NOVELTY - The method involves (i) adding terephthalic acid, glycol and sodium acetate into the reaction vessel for esterification reaction to obtain the esterified product, drying the single-layer graphene dispersion liquid dispersion to obtain dry oxidation graphene, adding dry oxidation graphene and ethylene glycol antimony into the esterified product, stirring and reacting to obtain polyethylene terephthalate modified slice; (ii) adding 9-boronbicyclo3.3.1nonane into 1/2 of the polyethylene terephthalate modified slice and reacting, (iii) mixing the product, 2-amino-pyrimidine and anhydrous ethanol, reacting, adding phytic acid, reacting and cooling to obtain the product A, (iv) adding polyacrylonitrile, silane coupling agent KH550 and glycol into remaining 1/2 modified slice, reacting, adding sodium hydroxide solution, centrifugal separation, adding magnesium and zinc chloride solution and reacting to obtain the product B; and (v) spinning the product A and B and knitting. USE - The method is useful for preparing flame-retardant anti-static polyester. ADVANTAGE - The method provides flame-retardant anti-static polyester with good durability and good flame retardance. The polyester has excellent flame retardant property and antistatic property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a flame-retardant anti-static polyester, is prepared as mentioned above.
