Abstract

The invention relates to the field of extinguishing materials, in particular to a dissolving-resisting-type foam extinguishing agent. The dissolving-resisting-type foam extinguishing agent is high inenvironment-friendly degree. The components of the dissolving-resisting-type foam extinguishing agent comprise, by mass, 40-60 parts of alkyl glycoside foaming agents, 10-20 parts of carbon hydrogen surfactants, 15-20 parts of biological polysaccharide, 6-15 parts of antifreeze agents, 4-6 parts of foam stabilizers, 4-6 parts of wetting agents and 20-40 parts of pure water. The dissolving-resisting-type foam extinguishing agent has the good foaming characteristic which is mainly shown in dense and lasting foams, the stacking speed is high, and contact of comburent and air can be quickly isolated. In addition, the dissolving-resisting-type foam extinguishing agent adopts the nonhazardous chemical raw materials and accordingly is small in pollution to the environment.

Description

technical field [0001] The invention relates to the field of fire-fighting materials, in particular to a solvent-resistant foam fire extinguishing agent, in particular to a solvent-resistant foam fire extinguishing agent with high environmental friendliness. Background technique [0002] Fire refers to the large-area combustion of combustibles caused by open flames caused by man-made or natural factors. Fires can be divided into six categories: A, B, C, D, E, and F according to the cause of the fire. Among them, class A fire refers to solid material fire, class B fire refers to liquid or meltable solid material fire, class C fire refers to gas fire, class D fire refers to metal fire, class E fire refers to live fire, and class F refers to fire inside cooking utensils. cooking materials (such as animal and vegetable oils) on fire. As society progresses, some emerging fires also appear in public view. Traditional fire extinguishing agents usually have a single function, and...
