Abstract

The invention discloses a ready-to-prepare sodium alginate hydrogel fire extinguishing agent which comprises modified sodium alginate hydrogel, filler and water-absorbent resin, the filler comprises a first additive, a second additive and a third additive, and the first additive is a conventional dry powder fire extinguishing agent and comprises ammonium dihydrogen phosphate, ammonium sulfate, auxiliaries and other materials. When the first additive is prepared, firstly, main materials such as ammonium dihydrogen phosphate and ammonium sulfate are crushed by a supersonic jet mill to obtain superfine mixed powder, and the mixed powder is fine in particle size, narrow in particle size distribution, high in overall surface activity and convenient for subsequent modification; according to the ready-to-prepare sodium alginate hydrogel fire extinguishing agent and the preparation method thereof, the component design is reasonable, the process operation is simple, preparation of the sodium alginate hydrogel fire extinguishing agent can be achieved, and the fire extinguishing agent is excellent in fire extinguishing performance and has high practicability.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a ready-to-mix sodium alginate hydrogel fire extinguishing agent. Background technique [0002] Among various disasters, fire is one of the main disasters that most often and commonly threatens public safety and social development, and when a fire occurs, fire extinguishers are our common fire fighting and rescue equipment. [0003] Among the existing fire extinguishing agents on the market, the most common fire extinguishing agents are water fire extinguishing agent, dry powder fire extinguishing agent, foam fire extinguishing agent, carbon dioxide fire extinguishing agent, haloalkane fire extinguishing agent, with the progress and development of science and technology, hydrogel fire extinguishing agent gradually entered Our sight, but the existing hydrogel fire extinguishing agent has poor mechanical strength, and it is easy to break through the covering layer...
