Summary: | The invention discloses a modified plastic particle and a preparation method thereof, and belongs to the technical field of functional plastics, the modified plastic particle comprises the following raw materials by weight: 100 parts of modified polyethylene glycol terephthalate, 4-6 parts of nano montmorillonite, 8-11 parts of an ethylene-methyl acrylate copolymer, 0.5-0.7 part of a coupling agent, 1.5-2 parts of a dispersant, and 0.6-0.8 part of an antioxidant; the raw materials are added into a double-screw extruder in proportion for extrusion and granulation, and the modified plastic particles are obtained. According to the modified polyethylene glycol terephthalate, functional diol is introduced in the polymerization process to form a block copolymer, the toughness can be effectively improved, and active flame-retardant components contained in a side chain can effectively improve the flame-retardant property; the modified polyethylene glycol terephthalate is used as a plastic matrix, and nano montmorillo |
