Pollution-free water-based fire extinguishing agent

Abstract

The invention discloses a pollution-free water-based fire extinguishing agent. The pollution-free water-based fire extinguishing agent is formed through mixing and stirring of the following components of, by weight, 34 parts of a hydrocarbon surfactant, 6 parts of ammonium polyphosphate, 20 parts of coconut oil alkyl betaine, 4 parts of cationic hydroxyethyl cellulose, 14 parts of dodecyl imidazoline, 2 parts of a fluorinated surfactant, 8 parts of urea, 7 parts of sodium chloride, 7 parts of polysorbate 20, 16 parts of an antifreeze agent, 15 parts of ethylene glycol and 53 parts of deionized water. The pollution-free water-based fire extinguishing agent can extinguish fires of the class A and the class B and can also be stored and attenuated with water for application in the environment with the temperature higher than -40 DEG C, and the defect that a traditional water-based fire extinguishing agent cannot be stored or attenuated with water for application in the environment with the temperature lower than -10 DEG C is overcome; in addition, the pollution-free water-based fire extinguishing agent is definitely safe in the processes of production, transportation, storage, application and the like and does no harm to human bodies; after the pollution-free water-based fire extinguishing agent is used, no residue exists; and after exceeding the time limit, the pollution-free water-based fire extinguishing agent can be used as an oil dirt cleaning agent and is environmentally friendly and harmless.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing agents, and in particular relates to a pollution-free water-based fire extinguishing agent. Background technique [0002] Water-based fire extinguishing agents can put out flammable solids (Class A), combustible fuels (Class B), combustibles (Class C) and other initial fires. Its fire extinguishing effect is obviously better than that of dry powder, 1211 and other fire extinguishing agents. Therefore, water-based fire extinguishing agents have been paid more and more attention by researchers and users. Most of the water-based fire extinguishing agents commonly used at present have a low freezing point of -10°C, which has poor low temperature resistance. However, the freezing point of -10°C greatly limits its application range. In a large number of countries and regions, the temperature in winter is lower than -10°C. ℃, and if the water-based fire extinguishing agent has solidified at ...

AI Technical Summary

Problems solved by technology

Most of the commonly used water-based fire extinguishing agents currently have a low freezing point of -10°C, which has poor low temperature resistance, and the freezing point at -10°C greatly limits their scope of application. In a large number of countries and regions, the temperature in winter is lower than -10°C. ℃, and if the water-based fire extinguishing agent has solidified at this temperature, it is already unusable and loses the function of fire extinguishing

In addition, inorganic salts, such as ammonium bicarbonate and carbonamide, are added to many water-based fire extinguishing agents. After chemical reactions between these inorganic salts and fire, a large amount of harmful gases will be produced, which not only pollutes the environment but also harms the human body.
