Abstract
The present invention relates to a composition capable of generating a high-efficiency fire-extinguishing aerosol, which comprises the components of the following proportion by weight: 65 to 74% of potassium nitrate, 6 to 11% of melamine, 5 to 9% of potassium ferricyanide, 4 to 8% of phenolic resin and 8 to 12% of potassium bicarbonate. The fire-extinguishing aerosol produced by the present invention has the advantages of no harm for people and livestock and no harm for an atmospheric ozone layer, and fire-extinguishing efficiency is from 30 to40 g/m<3>.
Description
The present invention relates to the aerosol fire-extinguishing technology, be particularly suitable for fire prevention and fire extinguishing confined space.
The known extinguishing chemical that is used for relative confined space mainly is be the fluorinated hydrocarbon of representative and nitrogen, carbon dioxide with " breathe out dragon ", and argon gas etc. are the inert gas class of representative.The common drawback of this two classes extinguishing device is that device volume is big, and heaviness involves great expense, the maintenance rate height.Particularly present widely used fluorinated hydrocarbon extinguishing device, because fluorohydrocarbon is to the destruction of atmospheric ozone layer, according to Montreal Agreement The International Protection ozone layer scheme, China limits the use of fluorohydrocarbon, total ban in 2005 since nineteen ninety-five.
The fire smothering gas colloidal sol that composition of the present invention produced, to the person poultry harmless, particularly do not damage atmospheric ozone layer, fire-fighting efficiency is 4～8 times of " breathing out dragon " class, and cheap, can be used as the update product of " breathing out dragon " and other inert gas agent.
Composition components proportioning of the present invention is as follows:
Potassium nitrate 65～74% (weight %, down together)
Melamine 6～11%
The potassium ferricyanide 5～9%
Phenolic resins 4～8%
Saleratus 8～12%
Preparation of compositions method of the present invention is, earlier phenolic resins is dissolved in the ethanol, make 10～30% solution, again other component is crushed to the fineness of 50～100 μ, and mixes, in the powdery components that mixes, add phenol resin solution then while stirring by ratio requirement, after mixing, cross 40 mesh standard sieves and carry out granulation, dry under 30～60 ℃ of temperature at last, make wherein volatile component be not more than 1% and get final product.
Embodiment:
Get 6% phenolic resins, be dissolved in 95% ethanol, make 20% solution.Get 69% potassium nitrate, in pulverizer, be ground into the powder of 50 μ～100 μ.
Get 9% melamine, 7% potassium ferricyanide, 10% saleratus is evenly fused, is ground into the powder of 50～100 μ then by pulverizer.
Above-mentioned two kinds of powders are put into mixer mix, add phenol resin solution then, and meanwhile continue to mix, until evenly.
By force by 40 mesh standard sieves, make it form single-size said mixture, put into the water-bath baking oven then, 55 ℃ of oven dry down.
