Abstract

The invention discloses a novel method for preparing a cold-resistant and seawater-resistant aqueous filmforming foam extinguishing agent. According to the formula, the cold-resistant and seawater-resistant aqueous filmforming foam extinguishing agent consists of the following raw materials in part by weight: 300 to 400 parts of composite burn resistance agent, 6 to 10 parts of sodium benzoate, 50 to 100 parts of urea, 5 to 9 parts of xanthan gum, 200 to 400 parts of amphoteric hydrocarbon surfactant, 20 to 40 parts of alkyl polyglucoside (APG), 80 to 200 parts of glycol, 30 to 60 parts of butyl cellosolve, 10 to 30 parts of FC115710, 20 to 60 parts of FC120320, 20 to 40 parts of low-molecular-weight fluorinated surfactant, and 20 to 60 parts of buffering agent. The product prepared by the method is low in cost, and suitable for fresh water and seawater; and after the agent and the seawater or the fresh water are mixed in a use mixing ratio, the foam property and the extinguishment performance of the agent change slightly, the expansion rate of foam is high, 25 percent liquid drainage time is long, the foams are stable, the extinguishment speed is high and the burn resistance performance is good.

Description

technical field [0001] The invention relates to a fire extinguishing agent and a preparation method thereof, in particular to a preparation method of a cold-resistant and seawater-resistant aqueous film-forming foam fire extinguishing agent. 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] The current anti-solvent aqueous film-forming foam fire extinguishing agent is only suitable for mixing with...
