Problems solved by technology

However, the traditional hydrolyzed protein foaming agents are mostly made of hoof horn grains and pig hair as raw materials. The foaming performance mainly depends on the surfactant composed of a large number of polypeptides and amino acids in the hydrolyzed protein solution, and the composition is relatively complex.
Although it is a relatively biodegradable component, the foaming effect is poor and the production cost is high

Abstract

The invention relates to the field of fire extinguishing materials, in particular to a foam extinguishing agent. The invention particularly relates to a sweater-resistant foam extinguishing agent which is prepared from the components in parts by mass: 10 to 15 parts of betaine surfactant, 8 to 10 parts of protein hydrolysate, 5 to 7 parts of chloride, 6 to 8 parts of urea, 7 to 9 parts of higher alcohols, 3 to 4 parts of sodium polyphosphate, 4 to 7 parts of stabilizer, and 30 to 60 parts of water. The sweater-resistant foam extinguishing agent provided by the invention has the advantages of fast foaming, good adhesivity, and nontoxicity of high-temperature reactants, can be widely applied to various class A fires and class B fires, and particularly has a favorable extinguishing effect onfires occurred on the sea surface.

Description

technical field [0001] The invention relates to the field of fire-fighting and fire-extinguishing materials, in particular to a foam fire-extinguishing agent, in particular to a seawater-resistant foam fire-extinguishing agent. Background technique [0002] Foam fire extinguishing agent, as the most widely used type of fire extinguishing agent, is widely used in municipal firefighting, petrochemical firefighting and other fields to fight solid fires and liquid fires, and plays an important role in ensuring the safety of people's lives and property. As a class of chemicals composed of surfactants with foaming properties and other functional additives, foam fire extinguishing agents have the risk of being released into the natural environment during the entire life cycle of production, storage, use, and disposal. The environment poses a potential threat. [0003] In recent years, sea fires have shown the characteristics of complexity, danger and harm, mainly in the concurrent...
