The invention relates to composite boron powder and a preparation method thereof, the composite boron powder takes vinylidene fluoride/allyl alcohol copolymer as a complexing agent, takes acrylic acid polyethylene glycol monobutyl ether ester/acrylonitrile/allylamine/hydroxyethyl acrylate copolymer as an auxiliary complexing agent, takes epoxy resin as a high-strength composite adhesive, takes diethylenetriamine as a curing agent, and is prepared by compounding the composite boron powder and the auxiliary complexing agent. The compound is prepared by adopting a secondary condensation method. Based on the mass of the boron powder, the mass of the vinylidene fluoride/allyl alcohol copolymer accounts for 1-2% of the mass of the boron powder, the mass of the acrylic acid polyethylene glycol monobutyl ether ester/acrylonitrile/allylamine/hydroxyethyl acrylate copolymer accounts for 0.3-1% of the mass of the boron powder, the mass of the epoxy resin accounts for 2-3% of the mass of the boron powder, and the mass of
