Abstract

The invention discloses an instant sodium alginate hydrogel fire extinguishing agent and a preparation method thereof. The instant sodium alginate hydrogel fire extinguishing agent comprises modifiedsodium alginate hydrogel, a filler and water-absorbent resin; the filler comprises a first additive, a second additive and a third additive; the first additive is a conventional dry powder extinguishing agent and comprises ammonium dihydrogen phosphate, ammonium sulfate, auxiliary agents and other materials. The preparation method comprises the steps: preparing a first additive, firstly crushing ammonium dihydrogen phosphate, ammonium sulfate and other main materials by using a supersonic jet mill to obtain ultrafine mixed powder which has the advantages of fine particle size, narrow particlesize distribution, high overall surface activity and convenience for subsequent modification. The invention discloses the instant sodium alginate hydrogel fire extinguishing agent and the preparationmethod thereof, wherein the instant sodium alginate hydrogel fire extinguishing agent is reasonable in component design and simple in process operation, preparation of the sodium alginate hydrogel fire extinguishing agent can be realized, and the fire extinguishing agent is excellent in fire extinguishing performance and relatively high in 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 and a preparation method thereof. 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...
