▎ 摘　　要

NOVELTY - A biomass graphene modified flame retardant comprises biomass graphene, flame retardant, and coupling agent. The amount of biomass graphene is 5-30% of the mass of the flame retardant, preferably 15%. USE - Biomass graphene modified flame retardant used for preparing biomass graphene modified flame-retardant polymer macromolecule masterbatch (claimed). ADVANTAGE - The biomass graphene modified flame retardant has anti-droplet function, strengthening function, anti-UV property, and coloring function. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) biomass graphene modified flame-retardant polymer macromolecule masterbatch which is prepared from biomass graphene modified flame retardant and macromolecule polymer material; and (2) production of biomass graphene modified flame-retardant polymer macromolecule masterbatch, which involves introducing biomass graphene modified flame-retardant into a target macromolecule polymer material through melting or mixing process.
