Wear-resistant PET transfer film and preparation method thereof

The invention relates to the technical field of transfer films, and particularly discloses a wear-resistant PET (Polyethylene Terephthalate) transfer film and a preparation method thereof. The wear-resistant PET transfer film comprises a PET base film, a coating layer, an adhesive layer and an aluminum foil layer which are arranged in sequence, the PET base film comprises the following raw materials in parts by weight: 40-42 parts of ethylene glycol; 80 to 90 parts of terephthalic acid; 0.04 to 0.06 part of a catalyst; 0.02 to 0.03 part of an auxiliary agent; 1-2 parts of a filler; the filler comprises alumina particles, the alumina particles are modified by a modifier, and the modifier is selected from PEG or a silane coupling agent. The preparation method comprises the following steps: S1, preparing the PET base film; and S2, preparing the transfer membrane. The wear-resistant PET transfer film can be used in the fields of various packaging materials, leather and the like, and has the advantages of wear res
