The present invention discloses a modified plastic particle and its preparation method, falling within the field of functional plastics technology. It comprises the following raw materials by weight: Modified polyethylene terephthalate 100 parts, nano-montmorillonite 4–6 parts, ethylene-methyl acrylate copolymer 8–11 parts, coupling agent 0.5–0.7 parts, dispersant 1.5–2 parts, antioxidant 0.6–0.8 parts; The raw materials are added in proportion to a twin-screw extruder for extrusion and pelletization, yielding modified plastic pellets. The modified polyethylene terephthalate in this invention forms a block copolymer through the introduction of functional diols during polymerization, effectively enhancing toughness. The active flame-retardant components incorporated into the side chains significantly improve flame-retardant properties. Using this modified polyethylene terephthalate as the plastic matrix, supplemented with nano-montmorillonite and ethylene-methyl acrylate copolymer, enables the production of functional plastic pellets with strong comprehensive properties and flame-retardant capabilities.
