Description
Technical Field
The invention relates to an environment-friendly anti-solubility aqueous film-forming foam extinguishing agent and a preparation method thereof, belonging to the technical field of fire fighting.
Background
At present, the requirements on the fire extinguishing agent at home and abroad gradually tend to the characteristics of environmental protection, multifunction, environmental protection rate and the like in recent years, most of the fire extinguishing agents produced in China are dry powder, and the dry powder fire extinguishing agent has obvious limitations, cannot cope with large-area fire, does not have the capability of resisting re-ignition and has harm to human bodies. The existing environment-friendly anti-solubility water film-forming foam extinguishing agent is only suitable for being mixed with fresh water to extinguish fire, but not suitable for being mixed with seawater to extinguish fire. The properties of the selected fluorocarbon surfactant and anti-burning agent are not suitable for being mixed with seawater, and once the fluorocarbon surfactant and anti-burning agent are mixed with seawater, the performance of the fluorocarbon surfactant and anti-burning agent is extremely unstable, and the foam performance and the fire extinguishing performance are greatly influenced.
The chitosan is prepared by extracting chitin as a raw material, is insoluble in water, can be dissolved in dilute acid, and can be absorbed by a human body. Chitosan is a primary derivative of chitin. The chemical structure of the polysaccharide is a high molecular basic polysaccharide polymer with cations, and the polysaccharide has unique physical and chemical properties and biological activation function.
