Problems solved by technology

The fire extinguishing agent used for ordinary fires is useless to forest fires, just like the dry powder fire extinguishing agent, because of its light weight, it is easy to be blown away by the wind, so it has little effect in front of forest fires and is fundamental to fire extinguishing. not working

Abstract

The invention relates to the technical field of chemical engineering materials, in particular to a fire extinguishing agent for fighting forest fire. The fire extinguishing agent comprises the following materials in percentage by weight: 40-50% of partially cross-linked water swelling acrylate-acrylic copolymers and microorganisms, the balance being 5% of fluorocarbon surface active agents, 12% of dodecyl dimethyl betaine, 8% of ethylene glycol and 25-35% of water, wherein the microorganisms are mainly bacillus subtilis, or can be bacillus subtilis-kind bacteria; the effective viable count of the microorganisms is 109 CFU / g; and the mass percentage of the microorganisms is 1.5-6%.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a fire extinguishing agent for forest fires. Background technique [0002] Fire is a double-edged sword, which can bring warmth and disaster to human beings. As long as you are slightly careless when using fire, serious consequences will occur. Among them, forest fire is the most difficult to control, which will cause huge loss of life and property. But the fire extinguishing in the world today basically still adopts untreated tap water and chemical foam to extinguish the fire. Use tap water to extinguish the fire. For a large fire that has already started, the internal temperature of the combustibles is already quite high. Tap water can only temporarily extinguish the flames on the surface of the combustibles. Resurrected. The fire extinguishing agent used for ordinary fires is useless to forest fires, just like the dry powder fire extinguishing agent, because of ...
