Zusammenfassung:The invention belongs to the technical field of polymer composite materials, and discloses a modified injection molding grade rPET material based on recycled PET as well as a preparation method and application of the modified injection molding grade rPET material. The modified injection molding grade rPET material is prepared from the following components in parts by mass: 90 to 95 parts of recycled PET, 5 to 10 parts of Surlyn resin, 0.5 to 1.0 part of an inorganic nucleating agent, 0.5 to 1.5 parts of a chain extender, 0.2 to 1.0 part of an anti-hydrolysis agent, 0.5 to 1.0 part of an antioxidant, 0.5 to 2.0 parts of a lubricating agent and 0.005 to 0.01 part of a whitening agent. The content of recycled PET in the material is 90% or above, and the material is excellent in mechanical property, good in processability, easy to color and high in toughness and can replace POM, PA, TPU and other primary engineering plastics to be applied to injection molding; the material does not contain glass fibers, can be su
