▎ 摘　　要

NOVELTY - Preparing graphene modified benzoxazine resin comprises (a) preparing benzoxazine intermediate and (b) modifying the benzoxazine intermediate, controlling the temperature of the benzoxazine intermediate to 80-85degrees Celsius, stirring, adding graphene nano sheet, continuously reacting until the reaction liquid is transparent, completing the reaction and obtaining graphene modified benzoxazine resin. USE - The method is useful for preparing graphene modified benzoxazine resin. ADVANTAGE - The method has simple and controllable production process, low production cost and ensures that the graphene modified benzoxazine resin has high cross-linking density, brittleness, rich toughness and rich flame retardant. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene-modified benzoxazine resin prepared by the above method.
