The invention belongs to the technical field of washing assistants, and particularly relates to a coated sodium percarbonate material as well as a preparation method and application thereof. According to the invention, a reversible coating material layer is formed outside sodium percarbonate to prepare the coated sodium percarbonate material with high moisture-proof stability and good release performance. Magnesium phytate or calcium phytate formed by sodium phytate and magnesium sulfate, magnesium chloride or calcium chloride is used as a coating layer, and the coating layer is wrapped by a bio-based material and is environmentally friendly and free of pollution. And the wrapped sodium percarbonate is difficult to dissolve in water, has high moisture-proof stability and can be stored for a long time. During use, the wrapping layer can be decomposed through phytase, and sodium percarbonate is released. The problems of sodium percarbonate coating and difficult coating decomposition are thoroughly solved. 本发明属于
