Problems solved by technology

[0003] However, most of the water-based fire extinguishing agents commonly used at present have fire extinguishing grades of 1A and 55B, and the fire extinguishing grade is relatively low; the lowest freezing point is -10°C, and the low temperature resistance is poor.
Due to the low level of fire extinguishing, it seems powerless for more serious fires, and the

Abstract

The invention discloses a preparation method of a water-based extinguishing agent. The preparation method comprises the following steps: heating water to 60-70 DEG C; adding diethylene glycol monobutyl ether the addition of which is 1%-10% of water, and stirring for the first time; sequentially adding urea, ammonium chloride, ammonium sulfate and diamine and stirring for the second time; cooling the solution to 30-40 DEG C; and adding sodium bicarbonate, and stirring for the third time. Correspondingly, the invention also provides a water-based extinguishing agent prepared by the preparation method. According to the water-based extinguishing agent disclosed by the invention, the rapid cooling effect can be achieved; the oxygen can be rapidly isolated; and effects of effectively extinguishing the fire and preventing after-combustion are achieved.

Description

technical field [0001] The invention belongs to the field of fire extinguisher manufacture, and in particular relates to a preparation method of a water-based fire extinguishing agent and the water-based fire extinguishing agent. Background technique [0002] The water-based fire extinguishing agent can extinguish the initial fire of combustible solid (Class A), combustible oil (Class B), combustible gas (Class C), and live equipment below 1000V. Its fire extinguishing effect is obviously better than dry powder, 1211 and other fire extinguishing agents. The water-based fire extinguishing agent has the characteristics of high fire extinguishing efficiency, strong anti-resurgence performance, no secondary pollution, non-toxic, non-irritating, etc.; it can basically be 100% biodegradable, and will not cause environmental pollution. Therefore, more and more researchers and users pay more and more attention to water-based fire extinguishing agents. [0003] However, most of the...
