Abstract
A fire-extinguishing aerosol not generating harmful substance for electric equipment (computer, communication equipment, electric generator, etc) is prepared from oxidant (strontium nitrate or strontium nitrate/potassium nitrate), reducer (guanidine nitrate or dicyandiamide) and modifier (potassium ferrocyanide, aluminium powder, carbon powder and phenolic resin). After it is ignited by sensor, a lot of fire-extinguishing particles are generated to cover on the object to be protected while the inert gas is generated for extinguishing fire.
Description
(1) technical field
The present invention relates to fire-extinguishing composite, the use of inhibition material refers in particular to the fire-extinguishing composite that uses and do not produce harmful substance at confined space.
(2) background technology
The nineties begins countries in the world all have ecological security in research the composition that is used for the enclosure space fire extinguishing.See CN97110882.X patent " the aerocolloidal composition and method of making the same of the formation that is used to put out a fire ".
This aerosol composition be with potassium nitrate as oxidant, be equipped with corresponding reducing agent dicyandiamide and auxiliary material phenolic resins and form fire-extinguishing composite.Cover the surface of protected object by its a large amount of solia particle of generation that deflagrates, and reach the fire extinguishing effect.This class is a large amount of potassium nitrites and the potassium oxide particulate that in use produces with potassium nitrate as the disadvantage of going out of the aerosol agent of main oxidant, has great corrosivity and destruction.This potassium nitrite and potassium oxide particulate have very strong hygroscopicity; when falling the equipment surface that needs protection, they can form drop by the airborne moisture of very fast absorption; these drops not only have extremely strong corrosiveness to equipment, and the film with electric conductivity that forms owing to these drops also can cause the short circuit of electronic equipment and other faults to be damaged simultaneously.
(3) summary of the invention
The purpose of this invention is to provide the component rational aerosol extinguishing agent of arranging in pairs or groups, they can not produce toxic gas in use and yet can not cause corrosion and damage protected equipment.
Embodiment of the present invention are to select the nitrate of the nitrate replacement alkali metal potassium of alkaline-earth metal strontium for use, to overcome the corrosivity of product, and add performance improver, reaction soon but do not produce the corrosivity phenomenon when their both satisfy to have been used, and adopt strontium nitrate and the two oxidants of forming of potassium nitrate to make its weight ratio 1.4～5, thereby then can satisfy sufficient reacting completely the oxygen balance needs neither can produce toxic gas and overcome corrosion phenomenon again.Oxidant potassium nitrate has swift advantage, and the oxidant strontium nitrate has the advantage that does not produce corrosion phenomenon.The present invention uses these two kinds of oxidant reasonable combination, and aerosol extinguishing agent then of the present invention in use neither produces poison gas, and corrosion phenomenon does not take place again.The present invention selects for use high guanidine nitrate of factor of created gase and dicyandiamide as reducing agent.The performance improver potassium ferricyanide is a kind of catalyst, can improve the integral combustion and the conversion ratio of aerosol composition.The adding of performance improver aluminium powder and carbon dust can improve aerosol extinguishing agent, and in use the combustibility of catabolite is complete to guarantee sufficient reacting.The adding of performance improver phenolic resins is respectively to form the adhesion-molded closely knit gas production charge column that becomes in order to make, and is convenient to make the integral combustion speed in installation and the assurance use.
Now the different proportionings of the aerosol extinguishing agent each component that the present invention is selected and its serviceability and effect are listed in table one: table one

Annotate 1: the corrosion and damage test is the red copper of 10 * 10 * 1mmpvc plastic sample plate and 20 * 50mm and aluminium sample board to be placed on aerosol be released in the space, after aerosol is released into, current mark does not appear in plastic sample plate surface, model weightening finish＜0.5%, insulaion resistance is not less than 10M Ω, then thinks no damageability.Green or blue corrosion mottle does not appear in red copper sample board surface, and corrosion pits such as whiting do not appear in aluminium sample board surface, then thinks non-corrosiveness.
Annotate 2: toxicity test is the result who the fire extinguishing smog that 20 small white mouses (10 public 10 mothers) place aerosol extinguishing agent to produce is placed 20 minutes.
Have the fast fire-fighting efficiency advantages of higher of reaction when from above-listed contrast table, selecting potassium nitrate as can be seen for use, but have obvious corrosive shortcoming as single-oxidizer.When selecting for use strontium nitrate and potassium nitrate to use as the binary oxidant, their both weight ratios maintain 1.4～5, not only non-corrosiveness but also avirulence of product when then using, reaction speed is fast when being equipped with appropriate reductant and performance improver again and this aerosol extinguishing agent being had use, and fire extinguishing is fast, the efficient advantages of higher.
Through further test confirmation, the potassium nitrate in the oxidant can partly or entirely be replaced by potassium chlorate or potassium hyperchlorate.Now comparative test result is listed in table two: table two
