Embodiment 1

[0056] Heat the mixing reactor to 55-60°C, add 20kg of water, 65kg of fluorocarbon surfactant FC1157, 28kg of sodium methylcocoyl taurate, stir for 30min, and then add 18kg of diisooctyl succinate in sequence Sodium sulfonate, 5kg of a mixture of ethylene glycol and propylene glycol (the volume ratio of ethylene glycol and propylene glycol is 4:6) and 18kg of dodecyl ether, continued to stir for 30min to obtain component A.

[0057] Add polyether modified silicone oil DY-ET101 into water and stir evenly to form a solution with a mass percentage of 60 wt%, to obtain component B.

[0058] The volume ratio of component A and component B is 7.5:2.5, and component A and component B will be stored separately.

Embodiment 2

[0060] 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 8:2.

Embodiment 3

[0062] 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 7:3.

Abstract

The present invention relates to a foam fire extinguishing agent with low temperature resistance, seawater resistance and high multiple miscibility with seawater, the foam fire extinguishing agent is composed of component A and component B, wherein component A is composed of perfluoroalkyl betaine Type surfactant, sodium methyl cocoyl taurate, anti-burning agent, antifreeze agent, lauryl ether and water, component B is an aqueous solution of silicon-containing surfactant. 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 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 which is low-temperature resistant, seawater-resistant and miscible with seawater at a high ratio, and its preparation and use methods. 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 agent a...
