Description
Technical field
The present invention relates to oils burning things which may cause a fire disaster fire extinguishing field more particularly to a kind of compound type aerosol extinguishing agent and its preparation sides
Method.
Background technology
Currently, it is common to use extinguishing chemical be broadly divided into following several classes：Water base class extinguishing chemical, gas class extinguishing chemical, powder
Body class extinguishing chemical, aerosol class extinguishing chemical and halon fire agent, all kinds of extinguishing chemical scope of applications are not quite similar, performance indicator
Respectively there is quality, wherein：Halon fire agent has the characteristics that good extinguishing effect, fire-fighting efficiency are high.
But there is the chemical composition of the destruction larger to ozone layer in halon fire agent, since 1987, respectively
State exists《Concerning the Montreal Protocol book for destroying ozone substance》Under limitation, it is phased out the production and use of halon fire agent,
The Chinese government also stops 1211,1301 extinguishing chemicals of production comprehensively from 2010.
Under the background that halon fire agent is eliminated, other class extinguishing chemicals have obtained wider development and application, water base class
The principle of extinguishing chemical mainly reaches fire extinguishing purpose by the cooling of water mists, asphyxia and isolation heat radiation effect；Gas class is gone out
Fiery agent is mainly to achieve the purpose that the fire that suffocates by spraying the oxygen content of inert gas reduction flame range；Powder class extinguishing chemical is main
Principle is to act on down ejecting powder by high pressure gas, consumes the free radical in flame, generation inert gas etc. and reaches fire extinguishing
Purpose.But the presence of hyperbaric environment is required for during these extinguishing chemical uses, cause equipment volume larger, storage uses
Have physical explosion dangerous in the process, in document " safety analysis of gas extinguishing system ", analyzes gas extinguishing system
Danger.
Existing aerosol class extinguishing chemical can be divided mainly into S types and K-type, and this kind of extinguishing chemical mainly utilizes redox reaction
The effects that inert gas of release, free radical, in flame range, is gone out by the chemical reaction of the asphyxia of inert gas, free radical to reach
The purpose of fire.Its deficiency is mainly shown：Redox reaction thermal discharge is big so that aerosol fire-extinguishing device structure spout temperature
Degree is higher；Some aerosol extinguishing agents generation aerosol is less efficient, and the time is long, is unfavorable for controlling initial fire disaster in time.
Therefore, the prior art needs further improvement and develops.
