Abstract
The present invention relates to a composition for generating a gaseous fire-extinguishing agent, which is prepared from an oxidizing agent, fuel, a performance additive agent and adhesive, wherein the oxidizing agent is strontium nitrate, or the mixture of the strontium nitrate and one or several of potassium nitrate, ammonium nitrate and barium nitrate; the fuel is one or the mixture of several of substances, comprising guanidine nitrate, nitroguanidine, sucrose, pentaamino tetrazole, etc.; the performance additive agent is one or the mixture of several of aluminium powder, magnesium powder and carbon powder; and the adhesive agent is one or the mixture of phenolic resin and shellac. The composition generates a chemical reaction by the initiation of currents to generate a gaseous fire-extinguishing agent, and the gaseous fire-extinguishing agent has the advantages of high fire-extinguishing efficiency, no harm to people and livestock, no harm to atmospheric ozone layers, no generation of greenhouse effect and no secondary damage to precision instruments, comprising computers, communication equipment, etc.
Description
(1) technical field
The invention belongs to fire-fighting domain; relate to the Chemical composition that produces gaseous fire extinguishing agent, be meant especially the gaseous fire extinguishing agent that is produced can be applicable to confined space with the total flooding mode put out a fire to human and environment safety and to the harmless Chemical composition that of the equipment of being protected.
(2) technical background
Because " breathing out dragon " class gaseous fire extinguishing agent that tradition is used has serious destruction as 1301,1211 pairs of atmospheric ozone layers, from the eighties, the extinguishing chemical that dragon all " is breathed out " in new the substituting of research in countries in the world.Wherein carrying out the on-the-spot technology that produces gaseous fire extinguishing agent of redox reaction with the number of chemical composition has obtained developing rapidly.Such extinguishing chemical fire-fighting efficiency is than " breathing out dragon " height, to ecological safety, and it is low that the fire extinguishing system of utilizing this technology to produce has a cost, install, store characteristics such as convenient, see number of patent application CN97110882.X " the aerocolloidal composition and method of making the same of the formation that is used to put out a fire ", " 99107850.0 aerosol fire extinguishing agent ", 998III984.9 " fire smothering gas colloidal sol forms material ".
Adopted potassium nitrate or barium nitrate as oxidant in the composition described in the above-mentioned document in a large number, low owing to its catabolite potassium oxide fusing point with potassium nitrate as oxidant, and has a strong hygroscopicity, it diffuses to the fire extinguishing space easily in a large number when fire extinguishing, when it is attached to the electric elements surface, can form and have corrosive conduction liquid film, thereby cause that easily electric elements damage, so it uses dangerous to electric equipment.And with barium nitrate as oxidant, in the processing of composition and use, cause that easily personnel poison because the compound of barium and plumbous compound the same be a kind of heavy metal compound that can cause in human body that precipitation is poisoned.
(3) content of the present invention
The purpose of this invention is to provide the Chemical composition that a kind of component reasonably produces gaseous fire extinguishing agent, improve fire-fighting efficiency, can make said composition in process and by electric current, cause gaseous fire extinguishing agent that its chemical reaction produces to human and environment safety, and do not damage equipment such as electrical equipment, precision instrument, effectively in confined space, put out a fire in the total flooding mode.
Embodiment of the present invention be select for use strontium nitrate to substitute potassium nitrate, barium nitrate is main oxidant, the fusing point of strontium nitrate solid phase catabolite exceeds two times nearly than potassium nitrate.Its diffusing capacity in fire-suppressant gas is considerably less like this, and particle diameter is also little, thereby it attachment occurs hardly at fire-extinguishing location, also can not form corrosivity conduction liquid film on the electrical equipment surface, has also avoided causing the barium salt problem, the problem includes: the heavy metal poisoning problem simultaneously.Because the reactivity of strontium nitrate is weaker than potassium nitrate, barium nitrate etc., therefore in composition in the selection of fuel (reducing agent), the present invention has selected for use reactive than dicyandiamide, guanidine nitrate that melamine is strong, nitroguanidine, sucrose and pentaamino tetrazolium etc., and the nitrogen burst size is big behind such fuel reaction, and is more favourable to fire extinguishing.
In this mixture, the percentage by weight of strontium nitrate accounts for 30%～70%, and the content of strontium nitrate is as being lower than 30%, and mixture will be difficult to keep necessary chemical reaction, as be higher than 70%, and it produces thing and is difficult to guarantee extinguishing property.Strontium nitrate also can part be replaced by a kind of or number (2-3 kind) kind among potassium nitrate, ammonium nitrate, the barium nitrate, thereby the composition hybrid oxidant, the use of hybrid oxidant not only can further improve extinguishing property but also can overcome independent use potassium nitrate, ammonium nitrate, barium nitrate as problems such as the caused infringement equipment of oxidant, toxicity.In hybrid oxidant, the percentage by weight of strontium nitrate must remain between 50% and 86%, just strontium nitrate: substituent=1～6: 1.
Can also add the performance additive of percentage by weight between 0%～10% in the mixture of the present invention, as aluminium powder, magnesium powder and powdered carbon etc., adding aluminium powder, magnesium powder are in order to regulate the heat that mixture is produced in course of reaction, thereby reach the purpose of reaction speed, to satisfy in the actual application requirement to differential responses speed.Performance additive also comprises the adding powdered carbon, adds an amount of powdered carbon, and it is more complete that oxidant is decomposed, thereby improves reaction efficiency.
Contain the adhesive of percentage by weight between 1%～15% in the Chemical composition that of the present invention, adhesive is selected phenolic resins and/or shellac for use, and adding adhesive is in order to make composition be convenient to machine-shaping.Phenolic resins and/or shellac are to add in the composition with 5%～15% alcoholic solution form.
Advantage of the present invention and effect be except that top described, can make whole Chemical composition that fire-fighting efficiency height in producing preparation, in the use in addition, nontoxic to people and animals, avoided infringement, particularly avoided secondary damage precision instruments such as computer, communication apparatus to atmospheric ozone layer and greenhouse effects.
