The existing water-based extinguishing agent has the following disadvantages:
1. a large amount of fluorine surfactant is used, and the fire-extinguishing agent is not easy to degrade after extinguishment and is toxic to the environment.
2. A large amount of flame retardant is added in the formula, so that the dissolution is time-consuming, the production efficiency is low, and the flame retardant has certain toxicity.
3. It cannot be used to extinguish fire in the kitchen due to its non-toxic nature.

In order to solve the technical problem, the invention discloses a water-based fire extinguishing agent which comprises the following components in percentage by weight: 1-10% of water-soluble sodium salt, 10-20% of antifreeze agent, 0.3-0.5% of thickening agent, 0.5-1% of foaming agent and the balance of water;
Further, the water-soluble sodium salt is one or more of sodium carbonate, sodium bicarbonate and sodium ammonium sulfate.
Further, the antifreeze is one or two of ethylene glycol and glycerol.
Further, the thickening agent is one or more of methyl cellulose, sodium alginate, agar, polyacrylate, vegetable gum and gelatinized starch.
Further, the foaming agent is one or more of betaine, sodium dodecyl sulfate and sodium dodecyl sulfate.
Further, it also includes: 0.5-1% of a surfactant.
Further, the surfactant is one or more of lecithin, stearic acid and polyoxyethylene sorbitan fatty acid ester.
Mixing water-soluble sodium salt, an antifreeze agent, a surfactant and 1/2-2/3 parts by weight of water, and stirring for 3 hours at a stirring speed of 1000-2000 r/min to obtain a mixed solution; adding the thickening agent and the foaming agent into the rest part by weight of water, and stirring for 2 hours under the condition of stirring speed of 1000-1500 r/min to obtain the water-based fire extinguishing agent
The fire extinguishing agent disclosed by the invention has the advantages that the water-soluble sodium salt is added, the esterification reaction is carried out on the fire extinguishing agent and edible oil in a kitchen under the high-temperature condition, the foaming agent is added to cover the surface of a combustion object to play a role in isolating air and inhibiting the re-combustion of the combustion object, the fire extinguishing agent is formed by matching the components of the fire extinguishing agent with other components such as the thickening agent, the anti-freezing agent and the like in the formula, three fire extinguishing methods of physical heat absorption cooling, oxygen inhibition and chemical permeation fire retardation are effectively combined together, the fire extinguishing agent has the characteristics of high cooling speed, high fire retarding efficiency, high re-combustion resisting rate and the like, the pH value of the prepared fire extinguishing agent is close to neutral, the environment after fire extinguishing is extinguished, the fire extinguishing agent is easy to clean and has no stimulation to human skin.
Detailed Description
The invention discloses a water-based fire extinguishing agent, which comprises the following components in percentage by weight: 1-10% of water-soluble sodium salt, 3-15% of flame retardant, 10-20% of antifreeze agent, 0.3-0.5% of thickening agent, 0.5-1% of foaming agent and the balance of water; wherein: the water-soluble sodium salt in the invention is one or more of sodium carbonate, sodium bicarbonate and sodium ammonium sulfate.
The thickening agent in the invention is one or more of methylcellulose, sodium alginate, agar, polyacrylate, vegetable gum and gelatinized starch.
The foaming agent in the invention is any one or more of betaine, sodium dodecyl sulfate and sodium dodecyl sulfate;
the antifreeze agent in the invention is one or two of glycol and glycerol.
The water-based fire extinguishing agent, water-soluble sodium salt and edible oil in a kitchen generate esterification reaction under a high-temperature condition, play a role in physically isolating and extinguishing fire, and can absorb oxygen and a large amount of heat, so that the fire is quickly weakened and extinguished, the addition of the foaming agent can form foam on the surface of the combustible, the foam covers the surface of the combustible, the contact between the combustible and the oxygen can be effectively blocked, and the burning resistance of the fire extinguishing agent is improved.
The addition of the thickening agent improves the viscosity of the fire extinguishing agent, so that the storage time of the fire extinguishing agent is prolonged, meanwhile, the fire extinguishing agent still has good viscosity at the temperature of a fire scene, the addition amount of the antifreeze agent is selected according to the requirement, the fire extinguishing agent with the freezing point of-15 ℃ is obtained after 10% of the antifreeze agent is added, and the fire extinguishing agent with the freezing point of-29 ℃ is obtained after 20% of the antifreeze agent is added.
