The invention discloses a thermostable composition, a polymer material composition and a preparation method and application thereof. The thermostable composition provided by the invention comprises 0.5-2 parts by weight of a bimetallic complex, 0.05-1 part by weight of an antioxidant, 0.5-2 parts by weight of a lubricant and 0.1-0.9 part by weight of an auxiliary stabilizer, central atoms of the bimetallic complex are rare earth elements and transition metal elements, and a ligand of the bimetallic complex is alkyl dithiocarbamate; the transition metal element is selected from one or more of aluminum, zinc, magnesium, tin and nickel; the auxiliary stabilizer is selected from one or more of phosphite ester, dipentaerythritol ester, epoxidized soybean oil, dibutyl maleate, dibenzoylmethane and hydrotalcite. The heat stabilizer can effectively improve the heat stability of a polymer material, and has relatively small balance torque.

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.
