Embodiment 11

[0044] A water-based fire extinguishing agent suitable for -10°C to 55°C, the composition of which is as follows in terms of weight percentage:

[0045]

[0046] The preparation method of the fire extinguishing agent of the present embodiment, as figure 1 As shown, according to the order of implementation, the steps are as follows:

[0047] A. Heat the water to 30-50°C;

[0048]B. Divide the water into two parts, one part is slightly more and the other part is slightly less, add antifreeze (ethanol) to the slightly less part of hot water, stir, after stirring evenly, add flame retardant (ammonium chloride) and stir Make it completely dissolve and mix evenly, and finally add a surfactant (hydrocarbon surfactant) with a pH value of 5.5-9.0 to make it completely dissolve. During this process, there is another part of slightly more hot water at 30-50°C Continue to add, and keep the temperature of the solution added with antifreeze, flame retardant, and surfactant at 30-50°C d...

Abstract

The invention provides a water extinguishing agent suitable for being used at -10-55 DEG C. The water extinguishing agent comprises, by weight, 5-10% of a fire retardant, 10-15% of an antifreeze agent, 0.9-1.5% of a surfactant and the balance water. The invention further provides a preparation method of the water extinguishing agent. According to the method, water is heated to 30-50 DEG C, the antifreeze agent, the fire retardant and the surfactant are added in sequence, the solution temperature is maintained at 30-50 DEG C, all raw materials are stirred to be completely dissolved, the solution is cooled to the room temperature, and the water extinguishing agent is obtained. Components of the extinguishing agent are evenly mixed, the extinguishing effect of the extinguishing agent is not influenced by long-time storage, extinguishing agent is wide in application range, good in extinguishing effect, free of toxicity and irritation and quite high in fire resistance and reburning resistance, 6L of water extinguishing agent can extinguish fire of 2A or 89 B level, the extinguishing speed is high, fire can be extinguished just in 20-40 seconds, the water extinguishing agent can be biodegraded completely after being sprayed, and the biodegradation is environmentally friendly and easy to clean after extinguishing.

Description

technical field [0001] The invention belongs to the field of fire extinguishing agents, in particular, the invention relates to a water-based fire extinguishing agent suitable for -10°C to 55°C and a preparation method thereof. Background technique [0002] Due to its cleanliness and environmental protection, water-based fire extinguishing agents are attracting more and more attention and are also widely used. Generally, a water-based fire extinguishing agent is a fire extinguishing agent that adds additives such as flame retardants, thickeners, and stabilizers to water. A layer of water film and micro-foam layer are formed on the surface of the burning object to seal the surface of the burning object, insulate the air, and form a heat insulation barrier. The liquid after absorbing heat vaporizes and dilutes the oxygen content of the air on the surface of the burning object, suffocating the burning object The effect prevents the continuation of burning and makes it achieve ...
