Problems solved by technology

However, although perfluorohexanone fire extinguishing agent has excellent fire extinguishing performance, it will produce HF acidic substances during storage, which will cause certain corrosion to the storage container, and in severe cases, the storage container will rupture and cause fire extinguishing agent leakage, etc. adverse effects

preparation example Construction

[0068] Another embodiment of the present invention also provides a method for preparing a fluorine-containing fire extinguishing agent, which includes the following steps: first, prepare materials according to the above-mentioned components of the fluorine-containing fire extinguishing agent; then, mix each raw material component according to the corresponding weight ratio uniform.

[0069] Since the above-mentioned isocyanate has good compatibility with perfluorohexanone, a homogeneous fluorine-containing fire extinguishing agent can be obtained by simple mixing, which is beneficial to the practical use of the fluorine-containing fire extinguishing agent.

[0070] Another embodiment of the present invention also provides the application of the above-mentioned fluorine-containing fire extinguishing agent in the preparation of fire extinguishing equipment.

[0071] The fire extinguishing equipment prepared by the fluorine-containing fire extinguishing agent is less corrosive an...

Embodiment 1

[0089] The fluorine-containing fire extinguishing agent of embodiment 1 is made up of following components:

[0090] Isophorone diisocyanate (IPDI) 0.1 g; and

[0091] Perfluorohexanone 360g.

[0092] The fluorine-containing fire extinguishing agent of Example 1 can be obtained by simply mixing the above components uniformly.

Embodiment 2

[0094] The fluorine-containing fire extinguishing agent of embodiment 2 is made up of following components:

[0095] Isophorone diisocyanate (IPDI) 1.8g; and

[0096] Perfluorohexanone 360g.

[0097] The fluorine-containing fire extinguishing agent of Example 2 was obtained by simply mixing the above components uniformly.

Abstract

The invention relates to a fluorine-containing fire extinguishing agent and a preparation method and application thereof. The fluorine-containing fire extinguishing agent comprises the following components in percentage by weight: 0.01%-0.5% of isocyanate and the balance of perfluorohexanone, and the isocyanate is selected from one or more of hexamethylene diisocyanate (HDI), dicyclohexylmethane-4,4'-diisocyanate (HMDI), isophorone diisocyanate (IPDI) and toluene diisocynate (TDI). The fluorine-containing fire extinguishing agent contains isocyanate and perfluoro(2-methyl-3-pentanone) with specific contents, and an isocyanate group in the isocyanate has good reaction activity and can remove moisture in the fluorine-containing fire extinguishing agent through chemical reaction, so that the perfluoro(2-methyl-3-pentanone) in the fluorine-containing fire extinguishing agent is prevented from generating HF acidic substances in the storage period to corrode a storage container. The compatibility of the added isocyanate and the perfluorohexanone is good, so that the use effect of the fluorine-containing fire extinguishing agent cannot be influenced under the condition of effectively removing water and preventing corrosion.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a fluorine-containing fire extinguishing agent and its preparation method and application. Background technique [0002] Fire extinguishing agent is a commonly used equipment material in the field of fire protection. There are many types of fire extinguishing agents, which can be divided into water-based fire extinguishing agents, dry powder fire extinguishing agents, foam fire extinguishing agents and so on. Among them, the water-based fire extinguishing agent mainly plays the role of extinguishing fire through the cooling effect of water. However, since the fire-fighting water for warehouses is generally taken from nature and contains certain impurities, it has a certain conductivity. The more electrolytes in the water, the greater the conductivity. Therefore, water-based fire extinguishing agents generally cannot put out electrical fires with water. [00...
