Abstract: The present application discloses a nanocomposite flame retardant. The nanocomposite flame retardant includes 9.7-9.8 wt % of MXene nanosheets, 72.7-76.5 wt % of bimetallic hydroxide and 13.8-17.5 wt % of cuprous oxide particles. The present disclosure further discloses flame-retardant bismaleimide resin added with the nanocomposite flame retardant and a preparation method of the flame-retardant bismaleimide resin. According to the present disclosure, the flame retardant is prepared from magnesium and aluminum elements, so the production cost of the flame retardant is reduced; and meanwhile, the particle size of the cuprous oxide particles is reduced, the specific surface area of cuprous oxide is increased, the catalytic efficiency of the cuprous oxide per unit mass can be improved, and then the flame-retardant and toxicity-reducing effects of products are improved.
