Summary: | 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.
