Hydrogel fire extinguishing agent and use method thereof

Abstract

The invention discloses a hydrogel fire extinguishing agent. The hydrogel fire extinguishing agent is white powder and obtained in the manner that 5-10 parts of acrylic polymers, 10-15 parts of carboxy methyl cellulose, 10-15 parts of corn starch, 5-10 parts of dispersing agent, 10-20 parts of fire retardant, 1-3 parts of hydrocarbon surfactant and the like undergo modified treatment. The obtained fire extinguishing agent has the conventional water cooling fire extinguishment function, and the fire extinguishing agent and water can form a hydrogel film resistant to high temperature, good in fire resistance and high in coverage performance and adhesion performance, and the hydrogel film can isolate air, extinguish fire by smothering and effectively prevent the fire from burning again; if the fire extinguishing agent is sprayed to an unburned area close to the fire, an isolation strip can form, so that the spreading tendency of the fire can be effectively controlled, and the fire extinguishing efficiency can be significantly improved. Besides, fire extinguishment residues are free of pollution, easy to degrade, safe, environmentally friendly and free of doing harm to human beings, plants and the like. In this way, the hydrogel fire extinguishing agent is wide in application range, can be applied to civil facilities, public facilities, plant-station disaster relief, forest fire and the like, the dosage of the fire extinguishing agent is small, and therefore the hydrogel fire extinguishing agent has significant advantages.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agent materials, in particular to a hydrogel fire extinguishing agent and a method for using the fire extinguishing agent. Background technique [0002] Fire is the great enemy of human beings, not only causing a large number of casualties, but also causing heavy losses of property and natural resources. At present, the fire extinguishing agents mainly include water, foam, dry powder, halogenated alkanes, carbon dioxide, nitrogen and some special-purpose fire extinguishing agents, among which water is the most commonly used fire extinguishing agent, which is widely used to put out fires in buildings, forests, grasslands and underground mines. The fluidity of water is very strong, and most of the water is often lost without functioning, resulting in a very low utilization rate, and the lost water not only loses the fire extinguishing effect during the flow process, but also causes second...

At present, the fire extinguishing agents mainly include water, foam, dry powder, halogenated alkanes, carbon dioxide, nitrogen and some special-purpose fire extinguishing agents, among which water is the most commonly used fire extinguishing agent, which is widely used to put out fires in buildings, forests, grasslands and underground mines. The fluidity of water is very strong, and most of the water is often lost without functioning, resulting in a very low utilization rate, and the lost water not only loses the fire extinguishing effect during the flow process, but also causes secondary losses, and even the possibility of penetration caused by water erosion Can cause spontaneous combustion again after extinguishing the fire

In order to improve the fire extinguishing performance of water and reduce the loss, people try to change the adhesion and flow properties of water by chemical methods to improve the fire extinguishing effect. For example, hydrogel fire extinguishing agent is a kind of polymer water system with fire resistance and strong adhesion performance. Fire extinguishing agent can effectively control the spread of fire and has excellent fire extinguishing effect. However, due to the introduction of polymers, the hydrogel fire extinguishing agent has the best time to delay fire control due to the long dissolution time when it is used. Large impact on the spraying range and other issues, limiting the use
