The invention provides a mineralized collagen artificial periosteum. The artificial periosteum is prepared from mineralized collagen in which nano calcium phosphonium salt and collagen fibers are arranged in order, has substances and micro and macro structures, which are the same as a natural periosteum, also has a favorable mechanical property and biodegradation properties, and can be used for replacing and restoring the periosteum. The artificial periosteum can limit other bone grafting materials in the bone fracture parts in the restoring process to prevent the bone grafting materials from coming out and muscles, fat and other tissues from being extruded into the bone fracture parts, so that the restoring effect cannot be influenced. The pore structure of the artificial periosteum facilitates revascularization and conveying of nutrient substances, thereby benefiting restoring of bone fractures. Since the mineralized collagen artificial periosteum consists of nano calcium phosphonium salt and the collagen fibers, the artificial periosteum can be gradually degraded along with regeneration of bone tissues and the periosteums in the body. The invention also provides a preparation method of the artificial periosteum.
