Problems solved by technology

[0004] However, the technologies disclosed in the above-mentioned prior art often have the following defects: 1) need to add such as inorganic salts as foam stabilizers, the addition of inorganic salts will cause precipitation during storage, and the storage period is shorter. The points are very complicated and the cost is high, 3) the anti-solvent effect is not good

Embodiment 1

[0046] Heat the mixing reactor to 75 to 90°C, add 18kg of water, 65kg of cocamidopropyl betaine surfactant, 18kg of sodium methyl lauroyl taurate, stir for 30min, and then add 18kg of succinate in sequence Sodium diisooctyl sulfonate; 8kg of a mixture of ethylene glycol and ethylene glycol butyl ether (the volume ratio of ethylene glycol and ethylene glycol butyl ether is 3:7); 4kg of alkyl glycosides, 15kg of dodecane base ether, and continued to stir for 30 min to obtain Component A.

[0047] Mix 0.6-0.7% non-ionic polyacrylamide solution with 0.4-0.5% carboxymethyl cellulose solution to obtain component B.

[0048] The volume ratio of component A and component B is 7:3, and component A and component B will be stored separately.

Embodiment 2

[0050] Component A and component B were prepared in the same manner as in Example 1, except that the volume ratio of component A and component B was 9:2.

Embodiment 3

[0052] Component A and component B were prepared according to the same method as in Example 1, except that the volume ratio of component A and component B was 6:3.

Abstract

The invention relates to a foam fire extinguishing agent which is solvent-resistant, seawater-resistant and can be miscible with seawater at a high ratio. Alkali surfactant, sodium methyl lauroyl taurate, anti-scald agent, antifreeze agent, alkyl glycoside, lauryl ether, and water, component B is non-ionic polyacrylamide solution and carboxymethyl Base cellulose solution mixture. And the method for preparing and using the foam fire extinguishing agent. Compared with the existing foam fire extinguishing agents, the foam fire extinguishing agent according to the present invention has longer storage stability, fewer types of ingredients, better foaming effect, better solvent resistance and is more environmentally friendly. In addition, the production cost of the foam fire extinguishing agent according to the present invention is lower, the preparation process is simpler, and it is more convenient for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting materials, and in particular relates to a foam fire-extinguishing agent that is solvent-resistant, seawater-resistant, and can be miscible with seawater at a high ratio, and a preparation and use method thereof. Background technique [0002] The aqueous film-forming foam fire extinguishing agent is an environmentally friendly fire extinguishing agent developed internationally, especially for fires on offshore ships and offshore drilling platforms. The development of an aqueous film-forming foam fire extinguishing agent that can be mixed with seawater at a high multiple is a current research hotspot. . Aqueous film-forming foam fire extinguishing agent is a fire extinguishing agent based on high-efficiency foaming agent. At present, the fire extinguishing agents used to extinguish oil fires in the world mainly include haloalkane (such as 1211, etc.), fluoroprotein foam fire extinguishing age...
