Problems solved by technology

At present, the common types of fire extinguishing agents can meet the requirements of most fires. However, it is difficult to remove the residues of fire extinguishing agents in the subsequent on-site cleaning, which has brought great damage to the environment.
And because the decomposition products of most fire extinguishing agents at high temperature are difficult to metabolize through biodegradation, they also have a greater impact on the ecology

Abstract

The invention discloses a water-based fire extinguishing agent which comprises the following components in percentage by mass: 1%-3% of butyl ether, 1%-3% of polyethylene glycol, 2%-5% of cocamidopropyl betaine, 2%-4% of a foaming agent, 2%-5% of urea, 2%-5% of sodium chloride, 3%-6% of alkyl glycoside, 1%-2% of a cationic surfactant and the balance of water. Compared with a traditional water-based fire extinguishing agent, different formulas and processes are adopted, and the prepared water-based fire extinguishing agent is excellent in fire extinguishing performance and does not pollute theenvironment after fire extinguishing.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing agents, and in particular relates to a water-based fire extinguishing agent. Background technique [0002] Fire refers to the large-area combustion of combustibles caused by open flames caused by man-made or natural factors. With the advancement of science and technology and the promotion of modernization on a global scale, the causes of fires are also quietly changing. In order to adapt to different types of fires, the types of fire extinguishing agents are also continuously improved and updated, in order to achieve the best extinguishing effect within the scope of minimum consumption. At present, the common types of fire extinguishing agents can meet the requirements of most fires. However, the residues of fire extinguishing agents are difficult to remove in the subsequent on-site cleaning, which has brought great damage to the environment. And since the decomposition products of mo...
