Embodiment 11

[0044] A cold-resistant water-based fire extinguishing agent suitable for -40°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 between 5.5-9.0 to make it completely dissolve. During this process, another part is slightly more than 30-50°C The hot water is continuously added, and the temperature of the solution added with antifreeze, flame retardant, and surfa...

Abstract

The invention provides a cold-resistant water based fire extinguishing agent suitable for the temperature from minus 40 DEG C to55 DEG C. The cold-resistant water based fire extinguishing agent comprises, by weight percentage, 15-25% of a flame retardant, 25-35% of antifreeze, 2-2.5% of a surfactant and the balance water. The invention further provides a preparation method of the fire extinguishing agent. The preparation method comprises the steps that water is heated to 30-50 DEG C, the antifreeze, the flame retardant and the surfactant are added in sequence, the solution temperature is kept in the range of 30-50 DEG C, all the raw materials are mixed until completely dissolved, the raw materials are cooled to the room temperature, and the cold-resistant water based fire extinguishing agent is obtained. The components of the fire extinguishing agent are uniformly mixed, and the fire extinguishing effect is not influenced after the long-time storage; and the fire extinguishing agent can be directly used without being mixed with water, the applicable temperature can reach minus 40 DEG C and can be as high as 55 DEG C, the applicable temperature range is wide, the fire extinguishing effect is good, and the range of the variety is wide; the fire extinguishing agent is free of toxin and stimulation and has the great flame resistance and reflashing resistance, and 6L of the fire extinguishing agent can reach the fire extinguishing levels of 2A and 89 B; the fire extinguishing speed is high, only 20-40 seconds are needed, the 100% biodegradation can be achieved after spraying, and the cold-resistant water based fire extinguishing agent is an environmental-friendly fire extinguishing agent and is easy to clean after fire extinguishing.

Description

technical field [0001] The invention belongs to the field of fire extinguishing agents, in particular, the invention relates to a cold-resistant water-based fire extinguishing agent suitable for -40°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 ma...
