Problems solved by technology

[0010] Some existing water-based fire extinguishing agents have many auxiliary agents and complex components, some of which are not helpful for fire extinguishing effect
Some formulas have a lot of surfactants added, which will generate more foam during use, which will affect the fire extinguishing efficiency
Additionally, the lack of coverage of the fire surface reduces chemical containment and suffocation

Abstract

The invention discloses a water-based extinguishing agent. The agent is composed of the following components of, by weight, 7-15 parts of flame retardants, 5-10 parts of thickening agents, 3-7 parts of preservatives, 1.0-1.5 parts of surfactants and 66-86 parts of deionized water, wherein the flame retardants are activated calcium carbonate, the thickening agents are polyvinyl alcohol, the preservatives are potassium sorbate or calcium propionate or mixtures of the potassium sorbate and the calcium propionate, and the surfactants are fatty alcohol-polyoxyethylene ether. The extinguishing agentis good in fire extinguishing performance, convenient to take and use, large in fire extinguishing area and good in covering effect.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to a water-based fire extinguishing agent. Background technique [0002] A substance that can effectively destroy the conditions of combustion and terminate combustion is called a fire extinguishing agent. The main modes of action of fire extinguishing agents are isolation, suffocation, isolation and chemical suppression. The fire extinguishing agents currently used in the Chinese market mainly include foams, dry powders, carbon dioxide, and halogenated alkanes. [0003] The fire extinguishing mechanism of foam fire extinguishing agent is cooling and suffocation. A continuous foam layer is formed on the surface of the burning object, and the foam and precipitated liquid are used for cooling, and at the same time, the covering effect of the foam layer is used for insulation to extinguish the fire. [0004] The fire extinguishing principle of dry powder fire extinguishing agent is main...
