▎ 摘　　要

NOVELTY - The preparation method of composite material involves dissolving graphene oxide powder in mixed solution and then mixing, adding modified sepiolite to the mixture and then reacting at 70-120 degrees C for 2-6 hours, adding caprolactam to the mixture and then polymerizing, extracting the mixture and drying. The modified sepiolite and graphene oxide powder are used in a mass ratio of (1-20):1. The graphene oxide powder and caprolactam are used in a mass ratio of 1:(10-200). USE - The method is useful for preparation of composite material, which is useful for spinning polyamide 6. ADVANTAGE - The method enables preparation of composite material with excellent flame retardant properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for composite material prepared by the method.
