The invention discloses a method for preparing a hemostatic material based on an air jet pulverization technology. The method comprises the following steps of (1) preparing a fibrinogen solution, wherein the fibrinogen solution comprises the following components of 2.5-3.5 wt% of fibrinogen, 10-25 wt% of trehalose, 2-10 wt% of glycine, 1.0-1.5 wt% of sodium chloride, 0.1-0.6 wt% of sodium citrate, 2.0-2.5 wt% of arginine hydrochloride and the balance of water for injection; (2) performing freeze drying on the fibrinogen solution, and performing air jet pulverization to obtain fibrinogen powder; (3) preparing a thrombin solution, wherein the thrombin solution is prepared from the following components of 0.1 to 0.5 weight percent of thrombin, 1.5 to 5.0 weight percent of trehalose, 0.3 to 1.0 weight percent of calcium chloride, 0.5 to 2.0 weight percent of glycine, 1.0 to 3.0 weight percent of cane sugar, 0.5 to 2.0 weight percent of dextran 20 and the balance of water for injection; (4) performing freeze drying on the thrombin solution, and performing air jet pulverization to obtain thrombin powder; and (5) mixing the fibrinogen powder with the thrombin powder, filling and drying to obtain the hemostatic material. The preparation process is simple, the period is short, and the prepared material is convenient to clinically use and excellent in hemostatic effect and has a wider application prospect.
