Zusammenfassung:The invention discloses a preparation method of a polymer amine flame-retardant modifier and application of the polymer amine flame-retardant modifier in a polyvinyl chloride wood-plastic composite material. The polymer amine modifier is characterized by being prepared from 1-20 parts of amine monomers with alkene double bonds and 80-99 parts of acrylate monomers in cooperation with an initiator and a dispersing agent under the suspension polymerization condition. The amine monomer is characterized in that molecules of the amine monomer contain polymerizable active amine of vinyl, allyl and acrylate groups. After the synthesized amine modifier is fully mixed with wood flour and polyvinyl chloride according to different proportions, the mixture is blended and extruded in a double-screw extruder, so that the compatibilized and modified PVC wood-plastic composite material is prepared. The wood flour and the PVC in the wood-plastic material have good flame retardance, and the problems thata traditional PVC wood-p
