The invention discloses a method for preparing a modified regenerated cellulose/alginate hemostatic composite material, and relates to a method for preparing a hemostatic material, belonging to the technical field of biomedical composite materials. The invention aims to solve the technical problem that an existing alginate material has an unsatisfactory hemostatic effect, poor structure integrity, and relatively low mechanical strength and stability. The method comprises a first step of modification of regenerated cellulose; a second step of preparation of an oxidized regenerated cellulose/sodium alginate water solution; a third step of molding of the hemostatic composite material; and a fourth step of cross-linking and solidification of the hemostatic composite material. According to the modified regenerated cellulose/alginate hemostatic composite material, due to the introduction of a sodium carboxylic acid structure at the C6 site of the regenerated cellulose molecule through the selective oxidization of a TEMPO-NaClO-NaBr oxidation system, the hemostatic property, structure integrity, mechanical strength and stability of the modified regenerated cellulose/alginate hemostatic composite material are improved, and the defects of poor wet strength, low mechanical integrity and easy deformation of ordinary alginate non-woven fabrics are overcome.

Water extinguishing agent and extinguishing method combing water extinguishing agent and fire-fighting unmanned aerial vehicle

The invention discloses a water extinguishing agent and an extinguishing method combing the water extinguishing agent and a fire-fighting unmanned aerial vehicle. The water extinguishing agent comprises the components: 30-50wt% of water retention agent, 20-35wt% of fire retardant, 10-30wt% of thickening agent and 0-10wt% of surfactant. The water extinguishing agent is mixed with water according to a ratio of (1-3):(99-97) to form a colloid-state fire extinguishing agent, the colloid-state fire extinguishing agent can be conveyed to fire scenes of a high-rise building and a super high-rise building above 100m through a fire-fighting water tanker, through vehicle-mounted high pressure pumping (power source), the fire-fighting unmanned aerial vehicle is remotely controlled on the ground to carry a water cannon sprayer and a pressure self-hold high-altitude fire-fighting liquid conveying pipeline to fly to a fire position and to horizontally spray the colloid-sate fire extinguishing agent for extinguishment, and the fire of the buildings are extinguished quickly through collaborated heating absorption cooling, dilution choking, and isolation covering action of various components. The water extinguishing agent is easy to store; a use method of the water extinguishing agent is simple; and the water extinguishing agent has the advantages of high fire-extinguishing efficiency, no environmental pollution, and the like. The fire-fighting unmanned aerial vehicle has more obvious application advantages in the high-rise building and the super high-rise building above 100m.
