The invention provides a method for mild and massive preparation of mineralization silk fibroin films. The method comprises the steps of silk fibroin film preparation, silk fibroin film enzyme solution preprocessing, phosphate deposition and calcium deposition so that the silk fibroin films with the completely-mineralized surfaces can be obtained. The obtained mineralization silk fibroin films can be used for bone repair materials for cartilage repairing, periosteum repairing, ligament repairing and the like. According to the method, no repeated soaking is needed, the preparation process is simple, the preparation conditions are mild, and the most preparation processes are performed at the temperature of 37 DEG C; the obtained mineralization area is large, the quantity is large, and the shape is controllable.
