Abstract
The invention discloses a synthesizing method of a closed negative-pressure drainage material. The synthesizing method comprises the following steps: (1) adding purified water into a 2000ml of three-mouth flask, then adding 150g of polyvinyl alcohol and dispersing uniformly; (2) increasing the temperature slowly until the temperature reaches the specific temperature, keeping the temperature and stirring continuously until the polyvinyl alcohol is dissolved sufficiently, and reducing the temperature until the temperature reaches the room temperature; (3) adding the mixture of an aldehydes condensing agent, an ester emulsifying agent, an aldehydes cross-linking agent and an alcohol dispersing agent into the three-mouth flask completely together, and continuously stirring until the mixture is uniform; and (4) adding foaming agents and catalysts, after the foaming, injecting foam mixing liquor into a mold for curing. According to the synthesizing method, the pore sizes of the closed negative-pressure drainage material can be controlled well and are uniform, so that the evenness of negative pressure and the absorbing stability of body fluid and necrotic tissues in the later-stage use process are facilitated, and the easily use property and the durability of the closed negative-pressure drainage material can be improved greatly.
