Abstract
The invention discloses a foam extinguishing agent. The foam extinguishing agent is composed of the following components in percentage by mass: 0.5-2.5 percent of perfluoro betaine, 1.7-2.3 percent of fluoroalkyl betaine, 3.2-5.9 percent of urea, 5.1-15.5 percent of modified succinate, 10-15 percent of n-octyl alcohol ether sulfonate, 10-16 percent of alkyl glycoside (0810), 10-20 percent of ethylene glycol, 0.25-0.45 percent of xanthan gum and the balance of water. The invention further discloses application of the foam extinguishing agent. A film generated by the foam extinguishing agent is larger in thickness and higher in stability, the fire extinguishing speed is high, and the fire extinguishing effect is better.
Description
Technical field
The present invention relates to a kind of fire foam.
Background technology
Fire foam can be divided into eggwhite type foam extinguishing chemical and synthetic foam extinguishing chemical by the matrix of synthetic foam.Eggwhite type foam extinguishing chemical mainly contains general proteins fire foam, fluoroprotein foam extinguishing agent, film forming fluoroprotein foam extinguishing agent, anti-molten and membrane proteins alcohol foam extinguishing chemical; Synthetic foam extinguishing chemical mainly contains high-expansion foam extinguishing agent, high, medium and low times of universal foam extinguishing chemical, aqueous film-forming foam extinguishing agent, anti-molten MJPZ extinguishing chemical, category-A fire foam.
In prior art, the thickness of the film that fire foam produces and stability are not strong, will decompose, not reach covering power, and cooling rate is excessively slow 300 DEG C-400 DEG C time, and make blow-off velocity slow, extinguishing effect is poor, easy resume combustion.
Summary of the invention
The object of the present invention is to provide a kind of fire foam, the thickness of its film produced and stability are comparatively strong, and blow-off velocity is fast, and extinguishing effect is better.
For reaching above-mentioned purpose, solution of the present invention is:
A kind of fire foam, be made up of by mass percentage following component: perfluor betaine 0.5%-2.5%, fluorinated alkyl betaine 1.7%-2.3%, urea 3.2%-5.9%, modification succinate 5.1%-15.5%, n-octyl alcohol ether sulfonate 10%-15%, APG (0810) 10%-16%, ethylene glycol 10%-20%, xanthans 0.25%-0.45%, surplus is water.
A kind of application of fire foam, will by mass distribution ratio perfluor betaine 0.5%-2.5%, fluorinated alkyl betaine 1.7%-2.3%, urea 3.2%-5.9%, modification succinate 5.1%-15.5%, n-octyl alcohol ether sulfonate 10%-15%, APG (0810) 10%-16%, ethylene glycol 10%-20%, xanthans 0.25%-0.45%, surplus is that the extinguishing chemical of water composition is mixed with the aqueous solution that mass fraction is 3%.
After adopting such scheme, the thickness of the film that the present invention produces and stability are comparatively strong, and blow-off velocity is fast, and extinguishing effect is better.
Because perfluor betaine, fluorinated alkyl betaine have excellent water and oil repellence and very low surface tension, therefore, when the foam coverage produced is at the pasta burnt, these two materials can drive and spread over equably on pasta rapidly, and these two materials can form thin film, tightly cover on pasta, reach the effect of fire smothering.Its two, perfluor betaine is a kind of amphoteric surfactant, and heat endurance is fine, and have excellent compatibility, 600 DEG C also can not be decomposed, and therefore, the thin film stability that this material is formed is extremely strong.
