This invention discloses a furfuryl alcohol copolymer-coated ammonium polyphosphate and its application in the preparation of flame-retardant composite materials, belonging to the field of flame-retardant materials technology. The invention involves mixing furfuryl alcohol, electron-accepting monomers, crosslinking agents, and initiators with ammonium polyphosphate in a solution, causing furfuryl alcohol, electron-accepting monomers, and crosslinking monomers to precipitate and polymerize on the surface of the ammonium polyphosphate, forming a furfuryl alcohol copolymer-coated ammonium polyphosphate. This furfuryl alcohol copolymer-coated ammonium polyphosphate, as a flame retardant, can be compounded with polyurethane foam, thermoplastic polymers, and thermosetting polymers to prepare polyurethane foam flame-retardant composite materials, thermoplastic flame-retardant polymer composite materials, and thermosetting flame-retardant polymer composite materials, respectively. The furfuryl alcohol copolymer-coated ammonium polyphosphate exhibits good dispersibility in the polymer matrix, good interfacial compatibility, and is easily modified, significantly improving the flame-retardant properties of the composite material while maintaining its excellent mechanical properties.
