The invention relates the medical biomaterial technology field. The existing clinical hemostasis dressing is only used for stopping blood, while the new biological dressing is only used for cleaning and healing superficial wounds and lacks a specific direction for treating posttraumatic wound, in particular, sea battle injury. The aim of the invention is to provide a method for preparing a hemostasis dressing with good volume expansibility, permeability, as well as obvious direction to deal with high-permeability seawater. The method for preparing the hemostasis dressing uses sodium alginate mixed by chitosan and various Na<+>/Ca<2+> as the basic material to form a hemostasis sponge with good mechanical strength after being cooled and dried, and prepares asymmetric seawater hemostasis dressing with porous layer and compact layer by using polyvinyl alcohol as the surface coating material. The dressing shows high expansibility and good permeability according to the results of volume expansibility, permeability and sem observation, has rich porous layer and compact water-resistant layer in microstructure, and is applied for stooping blood and healing wounds in high-permeability seawater environment.
