The preparation method comprises the following steps: preparing a pre-coating coating; preparing a release layer coating; preparing a base material through corona treatment; coating the base material with a pre-coating layer paint, and curing to form a pre-coating layer to obtain a pre-coated base material; and embossing and curing the release layer coating on the pre-coated base material by adopting a slit coating mode assisted by electron beams to form a release layer, and obtaining the release film for leather. The invention further discloses the release film for leather. The release film for the leather comprises a three-layer structure, namely the release layer synthesized by aliphatic polyurethane propionic acid resin, the pre-coating layer of water-based acrylic emulsion and the base material subjected to corona treatment; embossing and curing are cured by adopting an electron beam assisted direct rolling mode, so that embossing and curing are carried out at the same time, and the problem that a traditional release film is poor in flatness and texture fidelity due to limitation of the physical strength of a base material is solved; and the obtained product has the advantages of being vivid in texture, high in repeated utilization rate and good in solvent resistance, surface scratch resistance and flatness.
