Embodiment Construction

[0048] Novel multi-component water mist fire extinguishing additive of the present invention adopts Table 2 formula:

[0049] Table 2

[0050] components

[0051] The specific preparation steps of the formula are:

[0052] 1. Add 4% fluorosurfactant to the alcohols with 45% total mass of the solution, stir for 5-10 minutes and dissolve, the solution turns yellow.

[0053] 2. Slowly add octylphenol polyoxyethylene ether accounting for 12% of the total mass of the solution and N,N-dimethylformamide accounting for 0.5% of the total mass of the solution to the above solution in sequence, and stir for 2 to 5 minutes to dissolve into Uniform phase.

[0054] 3. Continue to add water accounting for 33% of the total mass of the solution. After stirring for 1 minute, the solution becomes a homogeneous phase, and the yellow color of the solution becomes lighter.

[0055] 4. In the above-mentioned light yellow solution, add successively account for 5% of the total mass of anh...

Abstract

The multicomponent fire-extinguishing water mist additive consists of fluoric surfactant 3-5 wt%, octyl phenol polyoxyethylene ether 2-20 wt%, alcohols 10-60 wt%, N, N-dimethyl formamide 0.5- 0.8 wt%, anhydrous sodium carbonate 1-10, sodium lactate 0.5-0.8 wt% and water 32-35 wt%. It is prepared through mixing the components and filtering.

Description

Technical field: [0001] The invention relates to a novel multi-component fine water mist additive and a preparation method thereof. The invention belongs to the technical field of fire-fighting fine water mist fire extinguishing. Background technique [0002] Additive-containing fine water mist refers to adding some high-efficiency fire extinguishing substances to the fine water mist, using water as the carrier to achieve the best combination of physical fire extinguishing and chemical fire extinguishing. Its physical fire extinguishing mechanism is mainly the oxygen isolation and cooling of the fuel surface by the fine water mist. Its chemical fire extinguishing mechanism is mainly to block the chemical reaction chain in fuel combustion (additives in fine water mist can be decomposed by fire heating to produce free radical inhibitors, which can capture free radicals generated during fuel combustion and make the combustion reaction The reaction chain in the fire is interru...
