Example Embodiment

[0018] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0019] The preparation method of the seawater-resistant type solvent-resistant aqueous film-forming foam fire extinguishing agent provided in this embodiment, its preparation steps include:

[0020] First, start the mixer, add 350 parts of deionized water, add 8 parts of sodium benzoate, and 30 parts of urea to dissolve them all; then, add 6 parts of xanthan gum to dissolve them all, stop stirring, after swelling for 2 hours, continue stirring and add coconut oil Add 200 parts of amidopropyl betaine, 30 parts of APG, 120 parts of ethylene glycol, and 30 parts of ethylene glycol butyl ether, and then evenly add 25 parts of F1203, 25 parts of FC1157, and 30 parts of F1460, and stir for 40 minutes to adjust the pH value of the material 7.6. Add 30 parts of buffer, continue to stir for 20 minutes, and stop stir...

Abstract

The invention discloses a seawater-resistant insoluble aqueous film-forming foam extinguishing agent and a preparation method thereof. The extinguishing agent comprises the following components in parts by weight: 300-400 parts of deionized water, 6-10 parts of sodium benzoate, 20-80 parts of urea, 5-9 parts of xanthan gum, 100-400 parts of Cocamidopropyl betaine, 20-60 parts of APG, 80-200 parts of ethylene glycol, 20-60 parts of ethylene glycol monobutyl ether, 10-50 parts of F1157, 10-50 parts of F1203, 10-60 parts of F1460 and 20-60 parts of a buffer agent. The seawater-resistant insoluble aqueous film-forming foam extinguishing agent is used for being mixed with seawater for fire extinguishing and has the advantages of low viscosity, high fire-extinguishing speed, high expansion rate, stable property, long storage time and the like.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, and more specifically relates to a seawater-resistant and solvent-resistant aqueous film-forming foam fire extinguishing agent and a preparation method thereof. Background technique [0002] In recent years, the requirements for fire extinguishing agents at home and abroad have gradually become environmentally friendly, multi-functional, and high-efficiency. The fire extinguishing agents produced in my country include foam fire extinguishing agents and dry powder fire extinguishing agents. Most of the foam fire extinguishing agents are suitable for mixing with fresh water. Suitable for seawater mixed foam fire extinguishing. Dry powder fire extinguishing agent has obvious limitations, it cannot put out large-area oil and alcohol fires, and its anti-resurgence performance is poor. [0003] However, the current anti-solvent aqueous film-forming foam fire extinguishing agent is onl...
