PET composite material masterbatch reproduced from recycled PET plastic bottles, preparation method and application of foamed shoe material

The invention provides PET composite material masterbatch reproduced from recycled PET plastic bottles, a preparation method and application of a foamed shoe material. According to the masterbatch and the preparation method thereof, melt mixing modification is performed on recycled reproduced PET and EVA matched with a macromolecular coupling agent to form a new macromolecular compound adhesive, and the composite material masterbatch is prepared by using a high-torsion extruder; the composite material masterbatch can be mixed with an ethylene-vinyl acetate copolymer (EVA) and a thermoplastic elastic material, and a shoe material is manufactured by utilizing a foam molding technology, so that the aims of recycling waste polyethylene terephthalate (PET), reducing carbon and protecting the environment are fulfilled, meanwhile, the requirement of a fresh PET high polymer material is also reduced, and the demand on petrochemical raw materials is reduced. 本发明提供一种回收PET塑料瓶再制PET复合材料母粒及制法与发泡鞋材的应用，其中，所述复合材料母粒及其制法，通过将回收再
