Problems solved by technology

At present, there are many types of fire extinguishing agents in the domestic market, such as water-based fire extinguishing agents, protein, fluoroprotein foam fire extinguishing agents, aqueous film-forming foam fire extinguishing agents, dry powder fire extinguishing agents, aerosol fire extinguishing agents, gas fire extinguishing agents, etc. There are few high-efficiency fire extinguishing agents that can extinguish extremely large fires caused by flammable liquids (Class B fires) and are not easy to re-ignition
Especially in the face of environmental protection requirements, some types of fire extinguishing agents commonly used in the past, such as fire extinguishing agents containing haloalkanes, have been gradually eliminated. At present, fluoroprotein fire extinguishing agents used in large quantities have short storage periods and strong odors, which have a negative impact on production and fire extinguishing processes.

Abstract

The invention discloses a universal high-stability foam extinguishing agent. The universal high-stability foam extinguishing agent is composed of a component A and a component B. The component A and the component B are dissolved in water and then rapidly mixed for a reaction, so thick compact high-stability extinguishing foam can be obtained through foaming. The high-stability foam extinguishing agent disclosed by the invention is good in fire control and extinguishing effects on A-type and B-type fire disasters, long in liquid segregation time and not easy to re-burn.

Description

technical field [0001] The invention relates to any general-purpose high-stable foam fire extinguishing agent for fire fighting and a preparation method thereof. Background technique [0002] With the diversification of people's production, life and energy structure, natural gas and fuel oil have replaced coal and wood as our daily fuel, and petrochemical products have entered all aspects of our production and life. It brings great harm to life and property, and also puts forward higher requirements for fire fighting. At present, there are many types of fire extinguishing agents in the domestic market, such as water-based fire extinguishing agents, protein, fluoroprotein foam fire extinguishing agents, aqueous film-forming foam fire extinguishing agents, dry powder fire extinguishing agents, aerosol fire extinguishing agents, gas fire extinguishing agents, etc. There are few varieties of high-efficiency fire extinguishing agents that can extinguish extremely large fires (Cl...
