Description
Technical field
The present invention relates to a kind of environment-friendly smoke-suppressing extinguishant and preparation thereof and using method.
Background technology
Fire has constituted great threat to the mankind's the security of the lives and property, the poisonous dense smoke that produces during fire particularly, the arch-criminal who causes scene of a fire casualties especially.Therefore, adopting extinguishment product fast and effectively, in time stamp out a fire, is the necessary means of redemption personnel life and property loss.In addition, along with the pay attention to day by day of the mankind to environmental protection, development environment close friend's green extinguishment product is also paid attention to by people day by day.
Widely used all kinds of extinguishing chemical products are all more or less existing weak point aspect extinguishing property or the environmental protection at present, and very limited for the inhibitory action of fire smoke.Breathe out imperial serial extinguishing chemical owing to contain the material that freon etc. damages the ozone layer,, will all eliminate by 2005 according to international Montreal protocol and " China breathes out imperial industry and eliminates plan ".The use meeting of fire foam pollutes scene of fire and water quality, and particularly Environmental Protection Agency and 3M company have announced to eliminate widely used perfluoro octane sulfonate (PFOS) in aqueous film-forming foam extinguishing agent.Powder extinguishing agent has toxic and side effect, can not use under military supplies or some specific environment, and anti-resume combustion is very poor, and the fire extinguishing effect is undesirable.Fine mist fire-fighting is the environment-friendly type fire-fighting technique that grows up over past ten years, have non-environmental-pollution, fire extinguishing rapidly, water consumption is low, to the destructive advantage such as little of protection object, therefore be counted as the main substitute of alkyl halide series extinguishing chemical, but simple fine mist fire-fighting still belongs to the physical action fire extinguishing, still exists deficiency on fire extinguishing effect and range of application.
For overcoming the defective that above-mentioned all kinds of extinguishing chemical product exists, to develop a kind of energy quick extinguishing, and can eliminate the poisonous dense smoke in the scene of a fire, environmentally safe, and extinguishing chemical with low cost will have crucial meaning for the development that promotes domestic and international fire-fighting cause.
Summary of the invention
The object of the present invention is to provide a kind of novel environment friendly smoke-suppressing extinguishant, it can fast and effeciently put out A, category-B fire, suppresses scene of a fire dense smoke, and easily biological-degradable, environmentally safe, and production cost is lower, does not still have bibliographical information at present.
Know-why of the present invention
The present invention is composite by surfactant, and the surface tension of water is reduced greatly, and because selected surfactant has unique amphiphilic structure, thereby can absorb heat fast, reach the purpose of rapid cooling.Simultaneously, surfactant molecule can be dispersed in the water fuel molecule at the outside package action that produces of fuel molecule, can not support burning because concentration crosses low.In addition, the extinguishing chemical molecule can also absorb the energy of free radical in collision process, suppresses chain reaction, thereby has prevented cigarette ash and smog that combined with radical forms, thereby has improved fireman's visibility and security.As seen, novel environment friendly smoke-suppressing extinguishant of the present invention can act on simultaneously three key elements in burning four key elements effectively, i.e. fuel, thermal source and free chain reaction, thus reach quick extinguishing and suppressed the purpose of fire smoke.
